`src/service.rs` should reject mismatches with `bridge_version_mismatch` before opening a connection so bridge-contract drift fails fast instead of crashing later on the first divergent RPC. - `plugins/host_dir.rs` metadata writes must keep the old symlink-leaf safety contract for plain ops (`chmod`/`chown`/`utimes` still reject symlink leaves), while the richer timestamp path should only mutate symlink metadata when the caller explicitly requests nofollow semantics (`lutimes` / `utimes_spec(..., false)`). - Mounted filesystem shutdown now happens explicitly during `src/vm.rs` disposal/reconfigure, not just in `MountTable::drop`. Bridge-backed mounts can therefore emit `SidecarRequestPayload::JsBridgeCall` during teardown, and host-visible flush failures should surface as the structured event `filesystem.mount.shutdown_failed` with the mount metadata plus the original error code/message. -- Guest runtime env setup in `src/execution.rs` must add writable `host_dir` / `module_access` mount roots to `AGENTOS_EXTRA_FS_WRITE_PATHS`, not just the VM shadow cwd.

Without those extra write roots, guest `fs.*` bridge calls misclassify writable mounts as read-only (`EROFS`) and cross-mount rename tests never reach the intended `EXDEV` path. - The native sidecar must run UNPRIVILEGED (non-root uid) AND under gVisor/runsc (Rivet Compute), so host-mount confinement cannot assume either root DAC bypass or Linux-only syscalls. Two consequences bind the `confine` boundary: (1) `openat2(RESOLVE_BENEATH)` is unsupported under gVisor, so the resolve-beneath walk must use plain `openat(2)` (see the `confine` module); (2) because the sidecar uid is not root, DAC permission checks are real and are NOT masked away — so confinement must not require MORE access than POSIX does. Concretely, metadata ops must not require READ permission on the target file (POSIX only requires search on the parent). Rules: - `stat`/`exists` use `confine::resolve_parent_beneath` + `fstatat`/`fstat` against `(parent_fd, leaf_name)` — never `open_beneath(O_RDONLY)` on the leaf, which would falsely report a statable-but-unreadable file (mode `0600` owned by another uid, or `0000`) as missing/`EACCES` under a non-root sidecar. - `chown`/`utimes` use `split_parent` + `fchownat`/`utimensat(.., AT_SYMLINK_NOFOLLOW/NoFollowSymlink)` after `reject_symlink_leaf`. `AT_SYMLINK_NOFOLLOW` on the mutation both keeps the leaf read-free AND closes the check→mutate symlink-swap TOCTOU (a leaf swapped to a symlink after the reject-check is operated on in place, staying confined, never followed to an escaped host path). diff --git a/crates/native-sidecar/Cargo.toml b/crates/native-sidecar/Cargo.toml index 6178fdce70..d2c9ad0c29 100644 --- a/crates/native-sidecar/Cargo.toml +++ b/crates/native-sidecar/Cargo.toml @@ -19,6 +19,7 @@ agentos-kernel = { workspace = true } agentos-sidecar-protocol = { workspace = true } agentos-native-sidecar-core = { workspace = true } agentos-execution = { workspace = true } +agentos-protocol = { workspace = true } agentos-vm-config = { workspace = true } agentos-vfs = { workspace = true } async-trait = "0.1" @@ -57,6 +58,7 @@ rusqlite = { version = "0.32", features = ["bundled"] } rustix = { version = "1", features = ["fs"] } scrypt = "0.11" serde = { version = "1.0", features = ["derive"] } +serde_bare = "0.5" serde_json = "1.0" sha1 = "0.10" sha2 = "0.10" @@ -69,7 +71,6 @@ url = "2" vfs = { workspace = true } [dev-dependencies] -serde_bare = "0.5" tar = "0.4" wat = "1.0" v8 = "130" diff --git a/crates/native-sidecar/src/execution.rs b/crates/native-sidecar/src/execution.rs index ef336720d7..0aa5f28d6c 100644 --- a/crates/native-sidecar/src/execution.rs +++ b/crates/native-sidecar/src/execution.rs @@ -123,11 +123,11 @@ use agentos_native_sidecar_core::{ listener_snapshot_response, local_endpoint_value, parse_kernel_http_fetch_response, parse_process_signal_state_request, process_killed_response, process_snapshot_entry_from_kernel, process_snapshot_response, process_started_response, - remote_endpoint_value, shared_guest_runtime_identity, signal_state_response, - socket_addr_family, socket_address_value, stdin_closed_response, stdin_written_response, - tcp_socket_info_value, unix_socket_info_value, zombie_timer_count_response, - SharedProcessSnapshotEntry, SharedProcessSnapshotStatus, SidecarCoreError, - VM_FETCH_BUFFER_LIMIT_BYTES, + remote_endpoint_value, resolve_command_line, shared_guest_runtime_identity, + signal_state_response, socket_addr_family, socket_address_value, stdin_closed_response, + stdin_written_response, tcp_socket_info_value, unix_socket_info_value, + zombie_timer_count_response, SharedProcessSnapshotEntry, SharedProcessSnapshotStatus, + SidecarCoreError, VM_FETCH_BUFFER_LIMIT_BYTES, };

Normal TS/Rust clients omit `env` entirely; explicit compatibility/runtime overrides still win. Covered beside the shared default and by thin-payload serialization tests. | +| 2 | done | P1 / high confidence | Sidecar owns root/bootstrap policy, and restrictive guest fs policy does not block startup. Normal clients omit the default root descriptor; TS/Rust bootstrap directory and command defaults, temporary client permissions, and post-create filesystem materialization are removed. Sidecar coverage proves guest deny-all is restored after readiness. | +| 3 | done | P1 / high confidence | Omitted AgentOS policy defaults to allow-all through one native/browser sidecar normalization. Clients omit policy and no longer expand partial policies or re-enforce tool binding permissions. Explicit deny and omitted-policy tests live in the sidecar. | +| 4 | done | P1 / high confidence | PTY creation, dimensions, live stdin intent, resize, native ACP terminal lifecycle, default shell selection, and raw command-line classification use explicit sidecar protocol fields/methods. Clients no longer encode terminal control in environment variables, parse command lines, choose/default a shell, queue operations before terminal startup, or emulate an interactive shell/prompt. Kernel/sidecar suites cover line discipline/raw mode, resize/SIGWINCH, signals, EOF, shell behavior, command-line grammar, and exit status. | +| 5 | done | P1 / high confidence | `spawn` and `openShell` are asynchronous in both SDKs and return only after the sidecar supplies the real kernel PID. Removed synthetic PID allocators/remapping, Rust's background launch and readiness watch, and TypeScript's pre-start stdin/close/kill/resize queues. The sidecar/kernel owns lifecycle, trees, groups, signals, and wait state; clients retain only bounded host callback/event correlation keyed by the real PID and wire process ID. Real TS/Rust lifecycle suites prove the returned PID is the process-table PID. | +| 6 | done | P1 / high confidence | VM environment/root/loopback/permission/bootstrap/package-mount defaults, execute cwd/env overrides, and ACP session cwd, runtime, args, env, MCP, protocol version, client capabilities, and flags are sidecar-owned. VM creation returns the resolved guest cwd/environment for read-only client views, while TS/Rust omit default execute overrides. The VM/configure and lockstep ACP protocols carry optional fields, both clients and the actor bridge omit defaults, and native/browser sidecars use shared normalization. | +| 7 | done | P1 / high confidence | Removed client pending-request registries, synthetic prompt cancellation, hydration/config caches, synthetic config mutations, duplicate-id checks, live-session lists, closed-id tombstones, and detached close tasks. Session state/list/close now use authoritative sidecar requests; close is awaited and idempotent, create/resume collisions are sidecar-owned, and clients retain only host callback/event/permission routing. Native/core sidecar plus TS/Rust SDK integration tests cover the boundary. | +| 8 | done | P1 / high confidence | The native ACP extension owns filesystem and terminal host methods against VM state: create/write/output/wait/kill/release/resize use sidecar process, PTY, bounded-buffer, signal, and lifecycle primitives. TS/Rust filesystem and terminal dispatchers, terminal registries, counters, output buffers, and Rust ACP shell helpers are removed. Native integration coverage proves these methods never call the client; unknown adapter-specific methods retain JSON-RPC `-32601`. | +| 9 | done | P1 / high confidence | TypeScript keeps Zod authoring, JSON Schema conversion, and callback Zod validation. The sidecar now exclusively owns CLI parsing, registry/help metadata, indirect and direct command dispatch, permission enforcement, callback timeout, and ACP tool-reference prompt assembly. Rust and TypeScript command emulators, timeout races, prompt formatters, and cached prompt state are removed; native sidecar/ACP tests own the behavior. | +| 10 | done | P1 / high confidence | Package projection persistence and public mount routing are sidecar-owned. TS no longer caches/replays packages, merges mounted directories, routes public fs calls directly to host backends, or enforces local EXDEV/read-only policy; it retains only exact caller-owned `js_bridge` handles that the sidecar cannot access. Rust's inert in-process mount map/trait and unsupported plain/overlay variants are removed. The runtime-core compatibility merged view is deleted. | +| 11 | done | P2 / high confidence | Cron grammar, defaults, job/run state, overlap policy, missed-fire reconciliation, alarm generations, lifecycle events, opaque cold-wake state, and serializable action execution are shared sidecar behavior. Native/browser sidecars execute `exec`; the native ACP adapter executes `session`, while the browser adapter reports its lack of background ACP support as a typed cron error. TS/Rust clients only arm one absolute alarm, retain host callback closures, and forward state/events. The actor persists a sidecar-owned opaque snapshot plus one generation-tagged durable wake action, with a real teardown/reboot test proving restoration. | +| 12 | done | P2 / high confidence | TS/Rust filesystem calls use sidecar/kernel primitives, including direct positional `pwrite`, native recursive mkdir, and typed directory entries; removed client read/modify/write, recursive copy/remove, ancestor probing, per-entry `lstat`, batch/recursive-exclude convenience loops, mounted-directory merge, path normalization, and local read-only/cross-device policy. Relative paths and `.`/`..` resolve in the shared sidecar against the VM cwd. Non-recursive flags are omitted and default in the sidecar. Kernel `move_path` preserves Linux `EXDEV`, and unmount rebuilds the execution shadow from the revealed VFS. The compatibility filesystem implementation is deleted. | +| 13 | done | P2 / high confidence | Replaced production TS/Rust create/wait/configure/register orchestration with one session-scoped `initialize_vm` request. The sidecar owns readiness, ordering, resolved env/cwd, explicit mount/package projection, callback-metadata registration, and rollback of partial VM state. Clients omit empty mounts/packages and no longer subscribe to readiness or carry a readiness timeout. Native/browser atomic rollback tests plus real TS, Rust, and actor cold-boot tests cover the transaction. | +| 14 | done | P2 / high confidence | Removed runtime TypeScript reads/validation of `agentos-package.json` and the unused host snapshot-bundle resolver. Package metadata and snapshots remain sidecar-owned. | +| 15 | done | P2 / high confidence | The legacy runtime was not browser support. Runtime benchmarks now use the public AgentOS API; the public runtime-core `NodeRuntime`, schema, kernel proxy, legacy runtime, tests, and exports are deleted. The redundant in-repo `secure-exec` façade and orphaned private registry compatibility harness are also deleted. Browser execution remains in `packages/runtime-browser` and its internal worker drivers are not client compatibility APIs. | +| 16 | done | P3 / high confidence | Removed Cargo probing, source-tree mtime scans, automatic Cargo builds, the published runtime Cargo helper, dev target probing/cwd injection, and the unused create/configure `bootstrapCommands` hooks from both production and legacy test-runtime paths. Tests invoke Cargo explicitly; runtime binary resolution uses an explicit override or published platform package and fails actionably when absent. | +| 17 | done | P3 / high confidence | Removed Rust `software`/`SoftwareKind`/`SoftwareInput`, TS `_softwareRoots`, unused snapshot resolution, and the dead `SoftwareDescriptor` request/`appliedSoftware` response wire path. TS `software` remains only as the allowed package-manager input and is forwarded as package paths. | +| 18 | done | P2 / high confidence | The follow-up legacy/default audit is complete through finding 18.72 below. Future regressions should be added as new numbered findings before implementation. | +| 19 | pending | P0 / high confidence | TypeScript shared-sidecar callback and event routing is not VM-isolated. Replace the single mutable request handler and global unfiltered event delivery with ownership-keyed registration, dispatch, and disposal. Completion requires two simultaneous VMs on one shared sidecar proving isolation for `js_bridge`, host tools, ACP callbacks/events, cron callbacks, warnings, and disposal. | +| 20 | pending | P1 / high confidence | Process completion is not sidecar-authoritative: exit may precede trailing output, TypeScript guesses completion with quiet timers, and Rust stops consuming output at exit. Make the sidecar emit all ordered output before one terminal event, remove client quiet-time/polling behavior, and cover the ordering in native sidecar plus TypeScript/Rust parity tests. | +| 21 | pending | P1 / high confidence | Captured process output is unbounded in both clients while the configured sidecar capture limit is not enforced by production execution. Implement sidecar-owned bounded run-and-capture behavior with a typed overflow error naming the limit and how to raise it; retain streaming process APIs and test both clients against a deliberately small configured limit. | +| 22 | pending | P1 / high confidence | Rust silently ignores bounded event-channel lag, which can lose output or terminal events and hang waiters; some routes also match only process ID. Convert lag into a typed terminal error and scope subscriptions by full ownership. | +| 23 | pending | P1 / high confidence | TypeScript drops explicit `streamStdin: false` through truthy checks, causing the sidecar's default `true` to apply. Preserve explicit false through every serialization layer. | +| 24 | pending | P1 / high confidence | TypeScript `execArgv` fires stdin write and EOF requests without awaiting them, allowing EOF to race the write and dropping rejections. Await write, close, and wait in order. | +| 25 | pending | P1 / high confidence | TypeScript parses Zod host-tool input twice, so transforms and refinements can execute twice or fail on already-transformed data. Retain Zod in TypeScript but parse exactly once. | +| 26 | pending | P1 / high confidence | TypeScript flattens typed sidecar rejection codes into message-only `Error` objects, preventing Linux-style `error.code` handling. Preserve code, message, and protocol details in an exported structured error. | +| 27 | pending | P1 / high confidence | TypeScript silently discards startup software entries it cannot serialize, so a VM may boot without caller-requested packages. Clients must reject structurally unserializable explicit input; the sidecar remains authoritative for package existence, format, manifest, and projection validation. | +| 28 | pending | P1 / high confidence | TypeScript races a client-owned ACP permission timeout against the sidecar-owned timeout/default. Remove the client policy timer and retain only callback routing. | +| 29 | pending | P1 / medium confidence | TypeScript retains every exited `ManagedProcess` for the VM lifetime, creating an unbounded duplicate of sidecar-owned history. Delete completed routing state or apply an explicit bounded route policy if late host correlation requires retention. | +| 30 | pending | P1 / high confidence | Rust opens a wire session per VM without a close-session operation and suppresses `DisposeVm` failures. Reuse a connection session or add explicit close semantics, propagate failure, and keep shutdown retryable. | +| 31 | pending | P1 / high confidence | Clients cache projected package, agent, and command state captured during configuration, contrary to live `/opt/agentos` authority. Remove caches and query live sidecar state. | +| 32 | pending | P1 / high confidence | TypeScript and Rust remove ACP callback/event routes before the sidecar confirms session closure. Retain routes through successful close or typed already-gone and preserve retryability after transport failure. | +| 33 | pending | P1 / high confidence | TypeScript creates/resumes an ACP session, performs a second state request, and only then registers routing, creating an event-loss and orphan window. Return sufficient state atomically or register and reconcile immediately. | +| 34 | pending | P1 / medium confidence | Native and browser ACP use separate behavioral state machines and already differ for adapter prompt/config behavior. Converge them on one shared ACP core with explicit adapter hooks. | +| 35 | pending | P1 / high confidence | Rust drops protocol fields such as `adapter_entrypoint` and silently filters malformed session values. Preserve the complete wire result and return typed decoding errors. | +| 36 | pending | P1 / high confidence | ACP discovery converts projected-state failures into empty/unknown-agent results and ACP cleanup suppresses resource failures. Propagate discovery errors and aggregate cleanup failures. | +| 37 | pending | P1 / high confidence | Rust cron host callbacks return unit and therefore cannot mark durable runs failed, unlike TypeScript. Return a typed callback result while retaining the legitimate host alarm/wake hook. | +| 38 | pending | P1 / high confidence | Public security documentation claims omitted permissions deny access while the sidecar defaults omission to allow-all. Correct every affected security, networking, and runtime page and guard the claim against regression. | +| 39 | pending | P1 / high confidence | The TypeScript README quickstart installs Pi but does not pass Pi in `software` before creating a Pi session. Use the checked explicit-package example and execute it as documentation coverage. | +| 40 | pending | P1 / high confidence | The claimed actor cron cold-boot test returns successfully when `AGENTOS_SIDECAR_BIN` is absent, and CI does not provide it. Make the real teardown/reboot path mandatory in CI. | +| 41 | pending | P2 / medium confidence | TypeScript and Rust independently build process trees from flat process lists. Move tree construction to the sidecar or remove the convenience API, then leave forwarding-only client coverage. | +| 42 | pending | P2 / medium confidence | The TypeScript compiler package creates `/tmp`, applies inconsistent `/root` cwd defaults, and retains a secure-exec-era request filename. Rely on the Linux base and one real process cwd without bootstrap writes. | +| 43 | pending | P2 / high confidence | Both clients expose process options that are never honored or behave differently across SDKs. Remove unsupported fields unless implemented once in the sidecar protocol with parity coverage. | +| 44 | pending | P2 / high confidence | Unknown ACP methods make a host round-trip even though TypeScript has no extension handler and always returns null. Return method-not-found directly in the sidecar unless a real host-extension API exists. | +| 45 | pending | P2 / high confidence | Production protocol packages retain a JSON payload codec and a large legacy test configuration parser despite lockstep releases. Migrate fixtures to BARE/typed configuration and delete compatibility paths. | +| 46 | pending | P2 / high confidence | Rust cannot distinguish omitted presence-sensitive configuration from explicitly supplied default-valued input. Represent presence with `Option` and preserve it on the wire. | +| 47 | pending | P2 / medium confidence | TypeScript retains a synthetic `AgentOsSidecarClient` lifecycle with IDs and maps unrelated to the authoritative wire lifecycle. Lease the real VM directly and retain only host lease/refcount state. | +| 48 | pending | P2 / medium confidence | TypeScript chooses the omitted overlay mode as `ephemeral`, duplicating the sidecar default. Keep the JS bridge host-owned but obtain the resolved mode from the sidecar. | +| 49 | pending | P2 / high confidence | Core declares unused heavy production dependencies and an orphaned `long-timeout` declaration. Remove them and regenerate locks. | +| 50 | pending | P2 / high confidence | The deprecated string package descriptor remains exported and a transpile-only test calls `defineSoftware(string)` despite the supported `{ packagePath }` type. Remove the legacy surface and typecheck the public API test. | +| 51 | pending | P2 / high confidence | Active CLAUDE/docs files describe obsolete JSON package manifests, an in-process runtime, contradictory permission defaults, and a deleted registry command. Align all guidance with the current architecture. | +| 52 | pending | P2 / medium confidence | Legacy ACP permission-method shims remain in both clients even though support varies by native adapter. Move compatibility into the adapter/sidecar and leave typed routing in clients. | +| 53 | pending | P3 / high confidence | TypeScript handles a structured `acp.session_event` compatibility shape with no current producer. Remove the dead branch. | +| 54 | pending | P3 / high confidence | TypeScript swallows event-listener exceptions and Rust silently drops some session/MCP conversion errors. Propagate failures or emit structured host-visible warnings. | +| 55 | pending | P3 / high confidence | The core README hand-maintains an API inventory containing removed options, nonexistent types, and obsolete fields.

That is not a reason for client-side +filesystem authority. The VFS already supplies its minimal root, and the +sidecar creates its shadow-root directories through trusted internal operations +before restoring the guest policy. A VM with explicit deny-all fs rights now +boots successfully while guest writes after readiness still fail with `EACCES`. + +### 4–5 — Terminal and process protocol + +The kernel PTY is the terminal; no layer should emulate one. The protocol should +start a process with argv/env/cwd and optional PTY dimensions/modes, return a +stable process ID and PTY handle, stream ordered events, accept stdin/EOF/resize +and POSIX signals, and expose the authoritative kernel exit status. `openShell` +is only `sh` attached to a PTY. The kernel already owns PID parentage, process +groups, sessions, signals, and reaping, so clients should only correlate IDs and +events returned by the protocol. + +The clients previously manufactured a numeric PID because `Kernel.spawn()` and +`openShell()` returned synchronously while process creation over the sidecar was +asynchronous. Both APIs now await creation and return the sidecar's kernel PID; +writes, resize, signals, EOF, and wait address the returned process over the +protocol. Launch failure rejects creation instead of creating a fake process that +later exits with code 1. + +`ExecuteRequest.pty` is now that standard terminal interface: presence requests +a kernel PTY, optional `cols`/`rows` set its initial window, and the existing +process handle receives stdin, EOF, resize, signal, output, and exit operations. +`keepStdinOpen` separately expresses streaming input without leaking the +executor's private control environment onto the client API. Browser execution +returns a typed unsupported response for PTY requests until its adapter provides +a real terminal implementation. + +### 8 — ACP ownership + +Filesystem and terminal ACP methods operate on VM state, so the active native +ACP extension implements them directly. `clientCapabilities` describes the +sidecar host surface; an upstream adapter may use any subset it understands. +Non-native/browser adapters that do not install that host surface must omit the +capability and return the ACP-standard unsupported/method-not-found response; +client callback code is never used to manufacture support. + +### 9 — Zod tools + +TypeScript remains the tool authoring surface: callers define tools with Zod, +the client converts the supported subset to JSON Schema, and the host callback +uses Zod to validate structured input. The sidecar uses the forwarded schema to +build guest CLI/help metadata, parse CLI or JSON input, enforce binding policy, +bound the callback, and send one structured callback payload to the client. + +Toolkit command names are sidecar policy. The registration protocol therefore +contains no command-alias fields: both clients send only the toolkit name, +description, and tool definitions, and the sidecar derives `agentos` plus +`agentos-`. Empty toolkit collections are omitted. + +### 10 — Caller-owned filesystem state + +TypeScript still has in-memory layer and exact `js_bridge` mount helpers because +those objects contain caller-owned JavaScript callbacks and memory that cannot +cross the process protocol. They are host resources, not a second guest VFS: +the sidecar chooses every mount/filesystem operation and invokes the exact +registered callback when needed. They do not create startup directories, +materialize a root, grant permissions, or perform VM bootstrap. Root defaults, +bootstrap, Linux path behavior, mount policy, and guest-visible errors remain +sidecar/kernel-owned. + +### ACP permission callbacks + +Permission handlers are host callbacks and must remain routable through the +clients. The clients now return an optional answer only when a host handler +actually responds. Missing sessions, missing handlers, dropped responders, and +timeouts produce no client-authored reply; the native ACP sidecar converts that +absence to its standard reject outcome. This keeps host-only callback state in +the host while putting the permission default in one adapter-owned place. + +### 11 — Rivet actor wake integration + +The sidecar owns schedule truth, but a host actor may suspend the VM. Emit an +idempotent `next_alarm_changed` integration event with the earliest durable wake +timestamp or `null`. Rivet's plugin ABI does expose `set_alarm`, but that method +only arms the actor's existing durable schedule queue; it does not deliver a +custom alarm event to this plugin. The AgentOS actor adapter must therefore +enqueue one generation-tagged internal `schedule_at` wake action. Rivet derives +and reports its alarm from that durable action. On wake, the adapter forwards the +generation to the sidecar, which makes obsolete/duplicate wakes no-ops, +reconciles missed fires, and publishes the next alarm. This hook wakes the +scheduler; it is not a second client/actor scheduler. + +Actor sleep disposes the VM and its in-memory sidecar scheduler. Before teardown +the actor now requests a bounded, versioned, sidecar-owned snapshot, stores the +opaque JSON value in actor SQLite, and returns it to a fresh sidecar scheduler on +cold boot. The sidecar validates and reconstructs grammar, job/run state, +counters, overlap state, and alarms; interrupted serializable runs are returned +for at-least-once delivery. The actor never parses jobs, applies defaults, or +becomes another scheduler. A real-sidecar regression test schedules a job, +tears the VM down, boots a new VM, and observes the restored registry. + +### 13 — Atomic VM initialization + +`initialize_vm` is one sidecar-owned transaction: create the VM, reach ready, +apply explicit mounts/packages, register host callback metadata, and either +return the resolved VM view or dispose every partially created resource. The +clients do not wait for lifecycle events or decide initialization order. + +One host-only route must exist before the request in the Rust actor path: a +`js_bridge` mount can receive filesystem calls while the sidecar is applying +explicit mounts. The Rust client therefore installs the opaque callback route +before forwarding `initialize_vm` and removes it if initialization fails. This +does not bootstrap the filesystem or grant guest filesystem rights; the sidecar +still chooses and performs every filesystem operation. The callback is the only +component capable of reaching the caller-owned filesystem object. TypeScript +keeps the equivalent exact mount-id-to-object callback for the same reason. + +## Additional legacy findings + +- **18.1 — done / high confidence:** Deleted the former compatibility runtime, + which contained a second bootstrap, process/terminal implementation, native + sidecar lifecycle, kernel proxy, and options schema. Benchmarks and active + tests now use the public protocol-owned runtime path; generated Secure Exec + compatibility consumes the AgentOS public packages instead of this duplicate. +- **18.2 — done / high confidence:** Audited the broad TS/Rust filesystem, cron, + session, process, and mount surfaces under items 4–13. Their authoritative + state/defaults now live in the sidecar; remaining client maps contain only + host callbacks, event subscriptions, and caller-owned resources that cannot + cross the protocol. +- **18.3 — done / high confidence:** Removed the dead configure-time + `bootstrapCommands`/`toolShimCommands` wire fields and TS alias replay. + Sidecar toolkit registration already installs the authoritative command + driver and aliases. Updated the stale `secure-exec-sidecar` protocol golden to + the canonical AgentOS schema name. +- **18.4 — done / high confidence:** Removed TS package/policy replay and + `registerLinkedPackage` state from mount reconfiguration. An omitted package + list now preserves the sidecar's live package mounts, commands, agent launch + records, and snapshot bundle; create-time permissions and loopback policy also + stay sidecar-owned. Sidecar and thin-payload coverage own this behavior. +- **18.5 — done / high confidence:** Removed the dead configure-time + `instructions` and `projectedModules` protocol/state fields. Removed + `moduleAccessCwd` and the implicit `module_access` plugin in favor of the + existing explicit `host_dir` mount. Cross-language protocol fixtures and + sidecar host-mount/module-resolution coverage now prove the smaller surface. +- **18.6 — done / high confidence:** Made `packagesMountAt` optional on the + lockstep wire protocol. Rust, TypeScript, and the actor bridge now omit it by + default instead of sending `""` or `/opt/agentos`; the package projection + selects `/opt/agentos` inside the sidecar and preserves explicit overrides. +- **18.7 — done / high confidence:** Configure-time packages, command + permissions, and loopback ports are optional patches rather than required + empty containers. Mount-only client requests now omit all three; the sidecar + preserves their authoritative state, while an explicit empty value remains a + real override. Native package/loopback and browser command-permission tests + cover preservation across a later omitted patch. +- **18.8 — done / high confidence:** Configure-time mounts are also an optional + patch. The sidecar separately tracks explicit operator mounts and its derived + package mounts, so package-only initialization omits `mounts`, omission + preserves operator mounts, and an explicit empty mount list clears only the + operator layer. Sidecar and TS reconfiguration tests cover all three cases. +- **18.9 — done / high confidence:** Removed both clients' `agentos`/toolkit CLI + parsers, help/list metadata builders, indirect dispatch paths, callback timeout + races, tool-reference markdown builders, and cached prompt reference. The + sidecar now derives all of this from its registered toolkit state. TypeScript + retains Zod conversion and callback `safeParse`; authoritative toolkit and ACP + prompt tests moved to the native sidecar. +- **18.10 — done / high confidence:** Moved ACP terminal creation, stdin, + bounded output capture, wait/exit, signals, resize, release, and session cleanup + into the native ACP extension. Removed the TS/Rust terminal host dispatchers + and the Rust-only duplicate shell fan-out implementation. The same sidecar + integration suite now owns filesystem and terminal host-method behavior and + asserts no client callback occurs. +- **18.11 — done / high confidence:** Removed the final inert `moduleAccess` and + `moduleAccessPaths` options from the runtime-core test compatibility types. + Explicit `host_dir` mounts remain the only host-path module access mechanism. +- **18.12 — done / high confidence:** Removed both clients' generic ACP host + request parsers and method emulators. The client callback now returns no + implementation for unknown adapter methods; the native ACP extension owns + supported host methods and emits JSON-RPC method-not-found itself. Dedicated + permission and Zod tool callbacks remain the only client-routed ACP hooks. +- **18.13 — done / high confidence:** Removed the Rust `ExecOptions` cwd default + and the TypeScript proxy's implicit execute cwd/environment payloads. VM create + responses now return the sidecar-resolved guest cwd and environment so clients + can expose accurate read-only views without duplicating or retransmitting + runtime defaults. Native/browser and TS/Rust serialization tests cover omitted + overrides and the `/workspace` sidecar default. +- **18.14 — done / high confidence:** Replaced client-authored + `AGENTOS_EXEC_TTY`, `COLUMNS`, `LINES`, and `AGENTOS_KEEP_STDIN_OPEN` execution + flags with explicit optional `pty { cols, rows }` and `keepStdinOpen` wire + fields. The native sidecar now creates/resizes the kernel PTY and translates + streaming-stdin intent into executor-private state. TS payload coverage, the + ACP terminal integration, and the Rust package-backed PTY E2E own the behavior. +- **18.15 — done / high confidence:** Removed the TypeScript and Rust raw-command + parsers, guest-command-map checks, direct-vs-shell selection, shell wrapping, + and the TypeScript synthetic interactive shell/prompt implementation. Clients + forward the untouched command line through `ExecuteRequest.shellCommand`; one + shared native/browser sidecar classifier preserves direct argv for plain + commands, verbatim `sh -c` input for shell behavior, and typed rejection of + blank input. Shared classifier tests, TypeScript wire tests, and the real Rust + client/sidecar command-line E2E own the prior behavior. +- **18.16 — done / high confidence:** Removed the production TypeScript client's + merged local/sidecar filesystem view and local mount policy. Public filesystem + methods always traverse the sidecar; only an exact host filesystem callback + registry remains for sidecar-originated `js_bridge` calls. Surfacing that + boundary exposed and fixed two sidecar bugs: cross-mount `move` now returns + Linux `EXDEV`, and unmount no longer leaks mirrored mounted files through the + execution shadow root. Sidecar-owned mount tests cover both, while the TS + integration retains transport and semantic round-trip coverage. +- **18.17 — done / high confidence:** Removed explicit `allowAll` policy + construction from both direct and actor-backed `agentos-shell` startup. The + shell now omits permissions like every normal client and receives the shared + allow-all default from the sidecar; explicit caller overrides forwarded by + actor options remain intact. +- **18.18 — done / high confidence:** Removed Rust's `mount_fs`/`unmount_fs` + methods, 25-method host filesystem trait, mount options, and local mount map. + That API never crossed the protocol and no filesystem request consulted the + map, so it falsely reported successful mounts that were invisible to the VM. + `MountConfig` now represents only sidecar-native plugin mounts; the formerly + rejected plain and overlay variants are gone. +- **18.19 — done / high confidence:** Removed TS/Rust absolute/normalized path + guards and protected-directory string policy. The shared native/browser + sidecar now resolves relative and non-normalized request paths against the VM + cwd before kernel dispatch; empty paths return `ENOENT`, and kernel/VFS policy + supplies Linux errno behavior. Rust directory typing now consumes the one + typed `readDir` response instead of issuing a client-side `lstat` per child, + and recursive mkdir is one native operation in both clients. +- **18.20 — done / high confidence:** Removed client-only `writeFiles` and + `readFiles` partial-result loops plus basename-exclusion filtering from both + SDKs and the actor contract. These were convenience semantics, not Linux or + protocol operations, and moving them into the sidecar would have added an + unnecessary second batch API. Examples now compose ordinary `mkdir`, + `writeFile`, and `readFile` calls explicitly. +- **18.21 — done / high confidence:** Removed the still-published + `runtime-core/cargo` helper and the test runtime's duplicate source-tree mtime + scan, automatic `cargo build`, Rust toolchain discovery, environment mutation, + and repository-cwd launch. Even compatibility/test runtime startup now uses + only the explicit sidecar override or published platform binary. +- **18.22 — done / high confidence:** Removed the TypeScript and Rust terminal + defaults for `sh` and streaming stdin (including TypeScript's extra `-i`). A + PTY execute request with no explicit executable now selects the standard + `sh` terminal and live stdin in one shared sidecar normalization; explicit + executable and stdin choices remain untouched. Shared default tests and the + TypeScript omitted-payload test own this boundary. +- **18.23 — done / high confidence:** Removed TypeScript/Rust synthetic PID + allocators, PID remapping, background spawn launch, shell readiness watches, + and pre-start operation queues. Process and shell creation now await the + sidecar, expose the returned kernel PID, and reject launch failures directly. + Clients retain only the host callback/event correlation that the sidecar + cannot perform. Real SDK lifecycle tests verify PID identity and behavior. +- **18.24 — done / high confidence:** Process snapshots previously discarded the + kernel's argv/cwd/exit timestamp and both clients manufacture start/exit + timestamps from when they happened to observe an event or snapshot. The + kernel/sidecar snapshot now carries guest argv/cwd and start/exit timestamps + end to end; TS/Rust observation caches, local fallback rows, and presentation + overrides are deleted. TS process listing/tree now await a fresh sidecar + snapshot and both clients preserve the kernel's stopped state. +- **18.25 — done / high confidence:** Removed the TS/Rust pending-session-request + registries, method markers, local prompt cancellation, and background + fire-and-forget cancel. A normal `session/cancel` request now uses the + sidecar transport's existing blocking-request interrupt; sidecar tests own the + synthetic cancelled-prompt and `via: "prompt-interrupt"` cancel responses. +- **18.26 — done / high confidence:** Moved duplicate session-id + rejection for create and resume into both sidecar implementations and removed + the TypeScript client collision checks. Removed TS/Rust modes, config, + capabilities, agent-info, and synthetic-config caches; state getters now read + the authoritative sidecar snapshot and surface transport failures. The + live-session listing and idempotent awaited close are now sidecar protocol + operations, so both clients also dropped closed-id tombstones and detached + close registries. The remaining client session map contains only host + callback/event/permission routes the sidecar cannot access. Native/core + sidecar tests prove collision, ownership-filtered listing, and idempotent close; + TS/Rust SDK integration tests prove the forwarding surface. +- **18.27 — done / high confidence:** Replaced both complete client cron + schedulers with one shared sidecar implementation. The sidecar now owns cron + and one-shot parsing, UUID/default-overlap selection, bounded job/run + registries, allow/skip/queue policy, missed-fire coalescing, generation-tagged + alarms, and lifecycle events. TS/Rust retain one absolute timer and host + callback correlations only; client schedule/list/cancel are asynchronous + protocol forwards. The actor plugin installs a narrow alarm hook that persists + a generation-tagged internal `schedule_at` action without interpreting cron + state. Shared sidecar tests cover grammar/defaults/overlap/errors, and native + browser plus TS/Rust tests cover wire and public behavior. The actor now stores + and restores a bounded opaque sidecar snapshot across full VM teardown, with a + real cold-boot regression and at-least-once replay for interrupted runs. + Serializable command actions execute inside both sidecars, native session + actions execute through the native ACP adapter, and unsupported browser + session actions complete with a typed cron error. Callback closures remain + host-only by design. +- **18.28 — done / high confidence:** TypeScript and Rust still answered + spawned-process list/get calls from client-cached command, argv, timestamps, and + exit state, while process signals returned before the sidecar transport completed + (Rust also discarded every signal error). Both list/get surfaces now await the + sidecar's process snapshot and the local registries retain only PID-to-host-route + state. Stop/kill now await and propagate the sidecar response; exited-process + idempotence and the bounded 1,024-entry exited snapshot history are sidecar-owned. + Native signal tests prove exited-vs-unknown behavior, and real TS/Rust SDK + process suites prove fresh list/get state and awaited control. +- **18.29 — done / high confidence:** Both process event paths still + invent successful exit codes when authoritative events disappear: TypeScript + polls until a process vanishes and returns `0`, while Rust maps a closed event + channel to `0`. TypeScript also turns an event-pump transport failure into exit + code `1`. Those compatibility fallbacks are removed: waits resolve only from + a sidecar `process_exited` event and reject on event-pump/channel failure. + Focused TS/Rust regression tests prove transport loss cannot become exit `0` + or `1`. +- **18.30 — done / high confidence:** Rust process stdin/EOF and shell + write/resize/close operations now await and validate exact sidecar responses; + TypeScript shell resize/close and both clients' process signals do the same. + `ExecuteRequest.timeoutMs` is an explicit optional wire field enforced by the + native sidecar process pump, which emits the real SIGKILL exit status; browser + execution returns typed unsupported instead of providing partial client-timer + behavior. TypeScript/Rust timeout races and detached control tasks are removed. + VM disposal now completes every cleanup step and propagates aggregate failures, + while startup cleanup logs secondary failures before preserving the primary + error. Sidecar timeout/signal tests, TS/Rust process E2Es, payload tests, and + focused teardown regressions own the behavior. +- **18.31 — done / high confidence:** `ExecuteRequest.processId` is optional and + production TypeScript/Rust process and shell requests omit it. Native and + browser sidecars allocate one bounded-monotonic correlation ID and return it + with the authoritative kernel PID; clients retain only that returned ID for + host output/control routes. Explicit IDs remain available to lower-level + sidecar adapters and tests, with empty/current/retained collisions rejected by + the native owner. Native/browser allocation tests, thin-payload coverage, and + real TS/Rust process and PTY suites prove response-before-event correlation. +- **18.32 — done / high confidence:** Public shell handles now use the + sidecar-returned process correlation ID; both clients removed synthetic + `shell-N` allocators and bounded closed-shell tombstone/exit-code stores. Live + maps contain only host output subscribers, explicit handle-closed state, and + in-flight exit tasks/promises. Once an exit route drains, late wait and + idempotent close read the sidecar's retained process snapshot instead of a + client lifecycle cache. Real TS/Rust PTY suites prove sidecar identity, + immediate closed-handle rejection, and repeated late waits. +- **18.33 — done / high confidence:** Removed production TypeScript's + synchronous socket lookup, signal-handler, and zombie-timer caches/background + refreshes, including the per-output signal query. Callers that need these + diagnostics already use the awaited `SidecarProcess` queries and propagate + transport errors. Deleted the duplicate cache-only tests; the lower-level + sidecar query tests remain authoritative. The former static compatibility + stubs were deleted with item 15. +- **18.34 — done / high confidence:** Replaced both production clients' + create/readiness/configure/tool-registration state machine with the atomic + `initialize_vm` transaction. Omitted mounts/packages remain omitted, the + sidecar returns resolved cwd/env and projected software, and native/browser + implementations dispose partial VMs on configuration or callback-registration + failure. Rust's public client readiness timeout and event subscription were + removed. A pre-initialization `js_bridge` callback route remains only where a + caller-owned filesystem may be invoked during mount application; actor + cold-boot coverage proves why that host-only route is required. +- **18.35 — done / high confidence:** Deleted core's 2,280-line duplicate test + runtime and made its explicit `test/runtime` compatibility surface re-export + runtime-core's existing test-only implementation. A regression exposed one + behavioral divergence—unmounting before lazy kernel initialization did not + remove the queued mount—so the surviving implementation now covers and + preserves that behavior. Core, TypeScript-tools, and secure-exec type/public + surfaces compile against the single copy. Item 15 remains open until those + consumers migrate and the surviving compatibility runtime can be deleted. +- **18.36 — done / high confidence:** Removed the duplicated 120-second ACP + permission timeout and Rust public timeout constant from both clients. The + native ACP adapter now owns the bound and includes `timeoutMs` in its callback; + TypeScript/Rust use only that forwarded value to bound host reply correlation + and clean pending routes. Missing replies are now also sidecar-defaulted as + recorded in 18.63. Sidecar callback coverage asserts the authoritative value, + and client permission regressions retain host routing/warning behavior. +- **18.37 — done / high confidence:** Removed client-authored JavaScript + `platform: "node"` and `moduleResolution: "node"` values. The VM config wire + model now preserves omission separately from an explicit default override, + TypeScript and Rust send only caller-supplied builtin/timer overrides, and the + native sidecar resolves omitted platform and module resolution. Rust now also + exposes the explicit high-resolution timer override for SDK parity. VM-config, + Rust serialization, and TypeScript wire tests prove defaults remain omitted. +- **18.38 — done / high confidence:** Removed Rust's malformed ACP permission + callback fallback from invalid JSON to `{}`; malformed trusted-sidecar input + now fails the callback like TypeScript instead of changing its meaning. + TypeScript's best-effort ACP/event subscriber boundary still isolates host + callback exceptions from the transport loop, but now reports every such + failure and malformed sidecar event through a host-visible warning instead of + swallowing it. Focused Rust and TypeScript regressions cover both paths. +- **18.39 — done / high confidence:** Removed production TypeScript's dead + native-mount credential/path parsers, duplicate host-path maps, and VM-to-host + path resolver left behind after ACP filesystem handling moved into the + sidecar. Also removed the unreachable local-VFS root snapshot fallback; + `snapshotRootFilesystem` now always forwards to the authoritative sidecar. + Mount, base-image, snapshot, and full native migration-parity suites pass. +- **18.40 — done / high confidence:** Removed production TypeScript's hidden + `spawn(..., { shell: true|string })` compatibility branch. It was not in the + public `KernelSpawnOptions`, had no Rust equivalent, and manufactured a lossy + command line with `argv.join(" ")`. Public `exec` still forwards its caller's + raw command line unchanged through `shellCommand`; focused coverage now tests + that supported path. The duplicate branch in runtime-core is deleted with + the compatibility runtime under item 15. +- **18.41 — done / high confidence:** Removed TypeScript/Rust root-snapshot + fallbacks that invented mode, uid, gid, empty file content, and UTF-8 encoding + when a sidecar response omitted them. The shared sidecar snapshot producer + already serializes complete Linux metadata; clients now preserve it verbatim + and reject malformed responses. Focused malformed/complete response tests and + real TypeScript snapshot coverage pass. +- **18.42 — done / high confidence:** Removed ordinary filesystem response + fallbacks that turned missing sidecar fields into `exists = false`, empty + directory listings, or implicit UTF-8 file reads. The sidecar already emits + explicit values for these operations; both clients now reject malformed + responses rather than fabricate valid Linux results. TypeScript and Rust + malformed-response regressions cover the boundary. +- **18.43 — done / high confidence:** Removed TypeScript/Rust `vm.fetch` + response defaults for status text, headers, and body. Native and browser + sidecars already normalize every HTTP response with those explicit fields; + clients now only validate/decode them and reject malformed responses. Focused + validation plus real guest-listener fetch coverage passes in TypeScript, with + matching Rust deserialization coverage. +- **18.44 — done / high confidence:** Removed client-authored root-filesystem + mode, base-layer flag, empty lower/bootstrap lists, and native-root read-only + defaults. The canonical VM config preserves omitted and explicitly supplied + default-valued fields separately; native/browser sidecar root conversion owns + the effective ephemeral, base-layer-enabled, empty-layer, and writable-native + behavior. TypeScript/Rust wire regressions, VM-config round trips, shared + sidecar conversion tests, and real overlay/native-root E2Es cover the boundary. +- **18.45 — done / high confidence:** Removed client-authored mount + `readOnly: false`, empty plugin config, and the host-dir/node-modules helper's + implicit read-only policy. Optional mount fields now cross the lockstep + protocol; the sidecar alone resolves an omitted mount to writable with `{}` + plugin config, matching a normal Linux bind mount. Package projection remains + explicitly read-only because it is built inside the sidecar. TypeScript/Rust + omission tests, protocol default tests, host-dir integration, mount/native-root + E2Es, and the anchored symlink-escape regression cover the behavior. +- **18.46 — done / high confidence:** Corrected the remaining item-3 leak: + TypeScript and Rust no longer expand omitted permission-rule operations, + paths, or patterns to `"*"`/`"**"`. VM config and the lockstep configure + protocol preserve omission separately from explicitly empty lists; the shared + sidecar permission evaluator applies wildcard semantics to omission and still + rejects explicit empty fields. Client serialization, generated-protocol, + shared evaluator, and native permission-flag tests cover the boundary. +- **18.47 — done / high confidence:** Removed TypeScript/Rust cron-event + fallbacks that converted malformed sidecar completion/error records into a + zero duration or generic `"cron action failed"` error. Both clients now + require the sidecar-owned result fields and reject malformed records; focused + cron manager regressions cover both missing-field cases. +- **18.48 — done / high confidence:** Removed TypeScript's limit-warning + fallbacks that converted missing names and malformed measurements from the + trusted sidecar into empty strings and numeric zeroes. Complete warnings are + forwarded unchanged apart from number decoding; malformed warnings are + rejected with a host-visible diagnostic, with focused dispatch coverage. +- **18.49 — done / high confidence:** Removed TypeScript ACP stderr/exit + identity supplementation. The protocol already requires `sessionId`, + `agentType`, and `processId`, and the native adapter always emits them; the + client now forwards those values verbatim and uses its session map only for + the host-only numeric pid. Rust already forwarded the sidecar identity. + Focused stderr and exit regressions prove stale client session metadata can no + longer replace adapter-owned event fields. +- **18.50 — done / high confidence:** Moved adapter-specific session config + category resolution out of TypeScript and Rust. `setSessionModel` and + `setSessionThoughtLevel` now forward only `sessionId`, category, and value in + one ACP request; the shared sidecar resolver chooses the adapter-reported + config id, applies read-only support, and produces the OpenCode-specific + unsupported response for native and browser adapters. Shared resolver/core + sidecar tests cover writable, missing, and read-only categories, while the + TypeScript client test proves no metadata lookup or interpretation remains. +- **18.51 — done / high confidence:** Removed client session-lifecycle gates + from ordinary ACP sends, cancellation, state/config reads, and legacy + permission replies. The sidecar now decides whether the supplied session id is + live and returns the authoritative error. `destroySession`/`destroy_session` + issue only the sidecar close request instead of running a duplicate + cancel-then-close sequence, and TypeScript no longer synthesizes an unsupported + cancel result because the native ACP adapter already owns and tests its + notification fallback. Local session entries now gate only genuine host event, + permission, exit, and prompt-text routes. +- **18.52 — done / high confidence:** Moved `PromptResult.text` assembly and + Rust's former byte/chunk bounds into one shared native/browser ACP sidecar + accumulator. The sidecar still streams every live `session/update`, returns + the bounded accumulated text on prompt responses, warns once at 80%, and + fails with an actionable limit error. TypeScript/Rust prompts now send one + request and consume the returned text without installing a client event + subscription or requiring local session state. Shared limit, synchronous and + resumable browser, real native ACP, and thin TypeScript tests cover the path. +- **18.53 — done / high confidence:** Removed the final client cron action + executor. The sidecar protocol now emits a typed asynchronous cron dispatch; + native/browser sidecars launch serializable commands themselves, suppress the + command output the clients previously discarded, complete runs from the real + exit status, and recursively launch queued follow-ups. Native session actions + perform create/prompt/close through the native ACP extension. TS/Rust execute + only opaque callback ids whose closures cannot cross the protocol. Shared + decoding, native ACP, browser command, runtime event, and client leak-boundary + tests cover the split. +- **18.54 — done / high confidence:** Removed VM-wide ACP instruction assembly + from TypeScript. TS and Rust now forward an explicitly supplied VM instruction + string once in `CreateVmConfig` and forward only per-session instructions on + `createSession`; native/browser ACP extensions read the VM value from sidecar + state and combine it with the session override. Shared combination tests, + native ACP integration, browser wire-state coverage, and the TypeScript + OS-instruction integration suite prove the sidecar-owned behavior. +- **18.55 — done / high confidence:** Removed the TypeScript companion package's + hidden runtime-driver/kernel fallback, filesystem/mount discovery, permission + synthesis, environment construction, and memory/CPU option translation. + Callers now provide one already-configured `AgentOs` VM; the package writes a + bounded request/runner, executes `node` once through the public protocol, + parses the compiler response, and cleans up without disposing caller state. + Its formerly skipped real-VM suite is enabled by default and all six tests + pass, including project emit and caller-owned-state preservation. +- **18.56 — done / high confidence:** Deleted the redundant private in-repo + `secure-exec` façade and its tests. Secure Exec compatibility packages are + generated in the compatibility mirror directly from AgentOS public packages, + so retaining a second hand-authored legacy export list only kept the removed + runtime API alive and could drift from the generated shim. +- **18.57 — done / high confidence:** Migrated runtime benchmark setup to the + public `AgentOs` API and deleted runtime-core's public `NodeRuntime`, legacy + runtime, options schema, kernel proxy, compatibility tests, and exports. + Browser worker drivers remain internal to `packages/runtime-browser`; they are + not an SDK-side runtime implementation. +- **18.58 — done / high confidence:** Deleted the orphaned `registry/tests` + compatibility harness, including its roughly 4,000-line private kernel proxy + and test runtime. The root registry package was excluded from the workspace, + its `check-types` script was a no-op, and its documented test recipe did not + exist, so it provided no active coverage. Authoritative client, sidecar, + kernel, and protocol suites remain in their owning packages. +- **18.59 — done / high confidence:** Removed TypeScript's remaining toolkit + name/description policy validation and moved it to the sidecar. Then removed + client-authored toolkit/registry command aliases from both SDKs and the wire + protocol; the sidecar derives `agentos` and `agentos-`. TypeScript + still owns Zod authoring, schema conversion, and callback `safeParse` as the + explicit item-9 exception. +- **18.60 — done / high confidence:** Removed `connectTerminal` from both SDKs, + including TypeScript host raw-mode/stdin/stdout/resize wiring and Rust's + synthetic ACP-terminal reservation logic. `openShell` over the process/PTY + protocol is the single terminal interface; applications explicitly connect + its data, input, resize, signal, EOF, and wait operations to their terminal UI. +- **18.61 — done / high confidence:** Removed Rust-only fixed exec-output and + VM-fetch response caps. Output and HTTP response bounds are already enforced + by the sidecar; the Rust client now behaves like TypeScript and only consumes + the bounded protocol result instead of killing or rejecting at a second + client-authored threshold. +- **18.62 — done / high confidence:** Removed the final synthetic TypeScript + shell-id fallback and unused process driver/cwd guesses. Shell handles require + the sidecar process ID. Empty host-callback registrations and non-recursive + filesystem flags are optional on the wire and omitted by both SDKs; native + root plugin config is also omitted instead of being expanded to `{}`. Focused + protocol and sidecar tests cover the sidecar defaults. +- **18.63 — done / high confidence:** Moved the ACP missing-permission-answer + policy out of both clients. The callback protocol now carries an optional + reply; clients forward an actual host answer or `None`, while the native ACP + adapter maps absence to its standard reject result. Sidecar unit coverage + proves both the missing and explicit-reply paths. +- **18.64 — done / high confidence:** Deleted the unexported duplicate sandbox + provider/mount/toolkit implementation from core. It had its own mount-path, + lifecycle, filesystem, and process-tool defaults but no production consumer; + the supported `@rivet-dev/agentos-sandbox` package remains the single explicit + integration surface, so no duplicate behavior was moved into the sidecar. +- **18.65 — done / high confidence:** Removed the unused session metadata map + from both clients, the protocol, and native sidecar state; the browser sidecar + had already ignored it and native never read it after insertion. Made overlay + mode optional on the wire and defaulted omitted mode to ephemeral in shared + sidecar code, removed the dead runtime-core root-descriptor converter that + manufactured nested filesystem defaults, and stopped storing empty env/false + stdin values in TypeScript process tracking. Required BARE collections such as + execute `args` remain explicit serialization: an empty list means no additional + argv entries and does not select runtime policy or a guest default. +- **18.66 — done / high confidence:** Deleted runtime-browser's test-only legacy + VFS migration shim, which recursively walked a caller-owned TypeScript + filesystem and manufactured root bootstrap entries. Browser converged tests + now boot with the browser sidecar's root defaults, and the unused client-side + snapshot-to-OPFS persistence adapter and its wrapper methods are removed. + Explicit public AgentOS snapshot requests remain protocol operations; no SDK + scans or reconstructs a filesystem during VM startup. +- **18.67 — done / high confidence:** Removed the second orphaned runtime-core + root-descriptor serializer and its unused descriptor/lower aliases, plus stale + core process, mount, snapshot, and error-classification imports/helpers left by + the deleted compatibility runtime. Scoped lint and package typechecks now + enforce that these legacy branches have no remaining consumers. +- **18.68 — done / high confidence:** Restored the Rust SDK's typed + `SessionNotFound` result without reintroducing a client session registry gate. + The ACP sidecar now emits the authoritative `session_not_found` error code for + missing or cross-connection sessions; Rust maps that typed protocol result to + its public error and TypeScript preserves the same code on the thrown error. + The real Rust create/prompt/close lifecycle test covers the behavior. +- **18.69 — done / high confidence:** Removed unused agent packages from the + TypeScript client's production dependency closure. Agent packages are package + manager inputs, not hidden client runtime behavior: callers explicitly pass a + package path, then `createSession(name)` forwards only the name and the sidecar + resolves its manifest and ACP entrypoint. Updated stale integration fixtures + that claimed agents were auto-projected to pass each tested agent package + explicitly; the real Claude filesystem/session path now guards this boundary. +- **18.70 — done / high confidence:** Removed the last stale core re-export of + runtime-core's deleted sidecar root-lower compatibility alias, plus unused + process, JSON-RPC, cron, schema, and cached environment members exposed by a + clean declaration rebuild and scoped lint. Explicit caller-supplied root + lowers still serialize through the VM-config schema; the client does not + manufacture or expose a second sidecar descriptor API. +- **18.71 — done / high confidence:** Removed the remaining TypeScript + sidecar-handle session/VM metadata options, lifecycle fields, bootstrap + cloning, and tests. This host-only metadata never reached a transport or + runtime consumer. The handle retains only real host concerns—placement, + cancellation, pooled-child ownership, disposal, and lifecycle visibility. +- **18.72 — done / high confidence:** Removed the final Secure Exec-branded + handshake identities from the native and browser TypeScript transports and + matched Rust's `agentos-client` identity. The non-empty fields are structural + authentication data for the local stdio connection, not guest/runtime + defaults; normal spawned sidecars do not configure a competing auth policy. diff --git a/examples/core/README.md b/examples/core/README.md index d49faec680..55d08afd1b 100644 --- a/examples/core/README.md +++ b/examples/core/README.md @@ -15,7 +15,7 @@ how it is configured. `AgentOs.create({ ... })` boots a VM in-process with its mounts, software, and network settings, and returns an `AgentOs` instance.

Workers can hang on exit if the shared sidecar's piped stdio handles stay open, so any new test entrypoints that bypass this setup file must dispose their sidecars themselves. - `NativeSidecarProcessClient.dispose()` enforces a graceful exit window then `SIGKILL`s the child if it ignores stdin EOF; `tests/native-sidecar-process.test.ts` covers the regression so future changes cannot reintroduce an unbounded teardown wait. - In `packages/core` tests that capture `spawn()` stdout/stderr via callbacks and then call `waitProcess(pid)`, drain one macrotask (`await new Promise((resolve) => setTimeout(resolve, 0))`) before asserting on the buffered strings. Native-sidecar `process_output` events can arrive one turn after the exit notification, and tiny outputs like `curl -s` bodies are the first thing to get lost if you snapshot immediately. - `NativeSidecarProcessClient.waitForEvent(...)` supports indexed `SidecarEventSelector` objects; prefer selectors over ad hoc lambdas on shared sidecar clients so buffered events stay O(1) to retrieve and `ownership` can pin a wait to one VM/session. - The native sidecar client's unmatched event buffer is intentionally bounded and fail-closed. If a test or runtime path can leave `runEventPump` idle while output events stream, expect `SidecarEventBufferOverflow` rather than unbounded buffering, and set a larger `eventBufferCapacity` explicitly only for cases that truly need it. -- When Node/Vitest code needs to shell out to Cargo, resolve it through `src/sidecar/cargo.ts` instead of assuming a login shell already put `~/.cargo/bin` on `PATH`. +- Runtime client code must never probe for or invoke Cargo. Repository tests that build the sidecar may invoke `process.env.CARGO ?? "cargo"` explicitly as test setup. - For `tests/wasm-commands.test.ts`, broad `-t "grep"` or `-t "sed"` filters can pull in unrelated `rg`, `gzip`, or cross-package pipeline coverage via substring matches. When a story only gates the `grep`/`sed` blocks, use the explicit case names or a narrower `--testNamePattern` that only matches those block entries. - For `tests/wasm-commands.test.ts` and similar long-running VM truth suites, prefer one shared VM per `describe(...)` block over one VM per individual test unless the case truly needs pristine bootstrap state. Per-test VM boots push the file into multi-minute runtimes and make the RC sweep look hung even when it is still progressing. -- Cross-workspace suites in `../secure-exec/registry/tests/*` import `@rivet-dev/agentos-core` from `packages/core/dist`, not directly from `src/`. After changing exported test-runtime code such as `src/runtime-compat.ts`, rebuild `packages/core` before trusting registry/package Vitest results. - The `examples/quickstart` package also resolves `@rivet-dev/agentos-core` from `packages/core/dist`; after TypeScript changes in `packages/core/src`, rebuild `packages/core` before rerunning quickstart acceptance commands. -- The synthetic `openShell()` fallback in `src/sidecar/rpc-client.ts` needs PTY-style output semantics for xterm-based harnesses: normalize terminal-visible line endings to `\r\n`, and route command stderr through the main `onData` stream instead of treating it like a separate non-PTY stderr channel. +- `spawn()` and `openShell()` are asynchronous because the client must return the + authoritative kernel PID from the sidecar. Do not restore synthetic PID + allocation, pre-start operation queues, or a client terminal fallback. - **Always verify related tests pass before considering work done.** - **All tests run inside the VM** -- network servers, file I/O, agent processes. - For `vm.exec()` cwd/path tests, prefer setting up files from inside the guest shell when the assertion is about command resolution or relative paths. VM filesystem API writes becoming visible to host-backed runtimes is a separate shadow-sync surface and should be tested independently. - For active agent-session/bash-tool filesystem regressions, cover the host read path in `tests/filesystem.test.ts` with a Claude llmock prompt. Long-lived session processes keep writing into the sidecar shadow root after a tool call returns, so `vm.readFile()`/`vm.stat()` need shadow reconciliation before the session itself exits. - Session tests that need launch argv or OS-instruction assertions should inspect `getSessionAgentInfo(sessionId)` from sidecar state instead of spying on `kernel.spawn`; `createSession()` now launches through sidecar RPCs. -- `closeSession()` is intentionally fire-and-forget. Cleanup tests can await the internal `_sessionClosePromises` map when they need deterministic post-close assertions, but active-prompt cancellation cases should trigger the public close and then assert on resource release plus prompt error outcome separately, because the in-flight ACP request and the close request share the same sidecar connection. -- If you add or change a fire-and-forget session close path in `src/agent-os.ts`, attach a local `.catch(() => {})` to the dropped promise. The real close result is still exposed through `_sessionClosePromises`, and dropping the promise entirely turns shared-runtime close races into unhandled rejection noise in Vitest. +- `listSessions()` and `closeSession()` are awaited protocol operations. The sidecar owns the live-session list and idempotent close semantics; do not add client session tombstones, close-promise registries, or detached close tasks. - Pi CLI session state currently reports the shared V8 host PID when multiple ACP sessions share one JavaScript runtime child. In cleanup tests, treat only host PIDs that are unique to a session as dedicated session roots; a shared PID is runtime-wide context, not three distinct leaked processes. - For projected npm CLIs in package tests, prefer `node /root/node_modules//dist/.js` over `/root/node_modules/.bin/*`. pnpm's generated `.bin` wrappers embed host filesystem paths, which are not stable or guest-visible inside the VM. - Browserbase VM tests should read credentials from host env as `BROWSER_BASE_API_KEY` / `BROWSER_BASE_PROJECT_ID`, alias them to `BROWSERBASE_API_KEY` / `BROWSERBASE_PROJECT_ID` in the guest env, and keep VM `network` permissions narrowed to `dns://*.browserbase.com` plus `tcp://*.browserbase.com:*` so remote Browserbase sessions work while direct guest egress stays denied. @@ -100,33 +108,51 @@ An agent's launch config lives entirely in its `/opt/agentos` package `agentos-p 3.

If a host-backed runtime needs the command visible on disk, materialize the stub unconditionally instead of skipping on `exists()`. -- In `src/runtime-compat.ts`, custom `createKernel({ filesystem })` snapshots need to be replayed through guest filesystem calls after `createVm()` when permissions allow it. Loading the root snapshot into the kernel alone is not enough for shell-launched WASM commands, because they read the sidecar shadow root and will miss pre-seeded files like `/hello.txt` unless those entries are mirrored there too. -- In `src/runtime-compat.ts`, `createWasmVmRuntime({ commandDirs })` is a stateful command-dir descriptor, not just a static command list: keep symlink-to-WASM alias discovery, basename-based `tryResolve()` for late-added binaries, and the descriptor’s internal command-path/module-cache bookkeeping aligned with the kernel mount path or the registry dynamic-module truth tests will drift out of sync. -- In `src/runtime-compat.ts`, `NativeKernel.processes` is not automatically shared with the native-sidecar proxy map. When `spawn()` wraps `proxy.spawn(...)`, mirror the proxy snapshot into `kernel.processes` immediately and after `wait()` so registry integration tests that read `kernel.processes.get(pid)` see the same root-process status transitions as the public compat kernel. - Declarative sidecar permission rules must use explicit `["*"]` wildcards for rule `operations` and `paths`/`patterns`; empty arrays are rejected by the native sidecar instead of being treated as implicit wildcards. - **Pi SDK llmock setup**: Pi reads Anthropic endpoints from `~/.pi/agent/models.json`, not `ANTHROPIC_BASE_URL`. For `createSession("pi")` tests, write a provider override such as `{ "providers": { "anthropic": { "baseUrl": "", "apiKey": "mock-key" } } }` inside the VM before creating the session. - Pi headless llmock tests should still pass `ANTHROPIC_BASE_URL` through the session env even with the `~/.pi/agent/models.json` override, because some Pi SDK request paths still consult the env-configured base URL during ACP-driven tool turns. -- `packages/core` agent-session tests execute secure-exec registry agent workspaces through their built `dist`/bin artifacts.

When bootstrapping from secure-exec `registry/native/c`, build `make sysroot` first and then run a second `make` for the concrete `build/...` targets so `SYSROOT` resolves to the patched tree instead of the vanilla SDK sysroot chosen at parse time; in that second pass, treat `sysroot/lib/wasm32-wasi/libc.a` as already built so `make` does not loop back through the patch pipeline because of preserved sysroot timestamps. +- Agent E2E fixtures must pass the tested agent package explicitly; never rely + on `createSession(name)` to discover an npm dependency.

Replace global terminal retention with ownership/process-scoped direct routing or an explicit byte bound, convert lag into a typed terminal error with the skipped count, and match full ownership. | | 23 | pending | P1 / high confidence | TypeScript drops explicit `streamStdin: false` through truthy checks, causing the sidecar's default `true` to apply.

The loss occurs later: + +- `get_session_modes()` (`session.rs:1547-1552`) filters non-objects and uses + `.ok()`, converting a malformed present value to `None`. +- `get_session_config_options()` (`session.rs:1579-1589`) uses `filter_map`, so + one malformed entry is removed while the method returns apparent success with + a shorter list. +- `get_session_capabilities()` (`session.rs:1593-1604`) filters non-objects and + uses `.ok()`, converting malformed present capabilities to `None`. +- `get_session_agent_info()` (`session.rs:1608-1614`) does the same for agent + info. + +There is a second silent-normalization source in the public Rust structs: + +- `SessionModeState` (`session.rs:641-651`) derives `Default` and has + `#[serde(default)]` on required `currentModeId` and `availableModes`. +- `SessionConfigOption` (`session.rs:662-690`) has `#[serde(default)]` on the + required `id`. + +Those defaults turn malformed adapter output into invented valid-looking +values. `SessionMode.id`, `ConfigAllowedValue.id`, and `AgentInfo.name` are +already strict; optional fields are already strict when present. + +A reliable real-sidecar repro is a `session/new` result containing: + +```json +{ + "configOptions": [ + { "id": "valid", "category": "custom" }, + { "id": "bad", "category": "custom", "readOnly": "not-a-boolean" } + ] +} +``` + +The shared sidecar accepts both objects because its model-category inspection +only needs the string `id`/`category` fields. Before Item 35, Rust returns a +one-element vector: the second entry fails `SessionConfigOption` deserialization +and `filter_map` silently removes it. After Item 35, the call must fail with a +typed error naming `configOptions[1]`. + +## Recommended implementation + +### `crates/client/src/error.rs` + +Add a public typed variant; keep the actual `serde_json::Error` as the source so +callers can distinguish decode failures without parsing message text: + +```rust +/// Trusted sidecar ACP JSON did not match the public Rust response type. +#[error("failed to decode ACP {context}: {source}")] +AcpDecode { + context: String, + #[source] + source: serde_json::Error, +}, +``` + +`context` must identify an exact field (`"modes"`, `"agentCapabilities"`, +`"agentInfo"`) or indexed entry (`"configOptions[1]"`). Do not reuse +`ClientError::Sidecar(String)`: that is the untyped behavior Item 35 is meant to +remove. + +### `crates/client/src/session.rs` + +1. Extend `AgentRegistryEntry`: + + ```rust + #[serde(rename = "adapterEntrypoint")] + pub adapter_entrypoint: String, + ``` + + Then copy `agent.adapter_entrypoint` in the `list_agents()` mapping and fix + the stale comment claiming the result is only an id. + +2. Import `serde::de::DeserializeOwned` and centralize conversion in small pure + helpers rather than repeating `.ok()`: + + ```rust + fn decode_acp_value( + value: Value, + context: impl Into, + ) -> Result { + serde_json::from_value(value).map_err(|source| ClientError::AcpDecode { + context: context.into(), + source, + }) + } + + fn decode_optional_acp_value( + value: Option, + context: &'static str, + ) -> Result, ClientError> { + value + .map(|value| decode_acp_value(value, context)) + .transpose() + } + + fn decode_acp_values( + values: Vec, + context: &'static str, + ) -> Result, ClientError> { + values + .into_iter() + .enumerate() + .map(|(index, value)| { + decode_acp_value(value, format!("{context}[{index}]")) + }) + .collect() + } + ``` + +3. Make getters all-or-error: + + - modes: `decode_optional_acp_value(state.modes, "modes")`; + - config options: `decode_acp_values(state.config_options, + "configOptions")`; + - capabilities: decode the optional value first, then retain the existing + documented normalization that an actually valid empty object means `None`; + - agent info: `decode_optional_acp_value(state.agent_info, "agentInfo")`. + + There must be no `Value::is_object`, `.ok()`, or `filter_map` left in these + four paths. Omitted optional wire fields remain `None`; a present malformed + value is an error. The config list must never return fewer entries than the + sidecar supplied. + +4. Route syntax failures in `parse_optional_json()` and `parse_json_vec()` + through the same `AcpDecode` variant. Make `parse_json_vec()` enumerate its + inputs so invalid JSON is also labeled `configOptions[N]`. This gives one + stable error contract for both invalid JSON text and JSON that does not match + the typed public shape. + +5. Remove silent required-field defaults: + + - remove `Default` from `SessionModeState` and remove `#[serde(default)]` + from `current_mode_id`/`available_modes`; + - remove `#[serde(default)]` from `SessionConfigOption.id`; + - update the comments that currently document the lossy behavior. + + Repository search currently finds no construction through + `SessionModeState::default()`, so this is not needed internally. Lockstep + releases have no backward-compatibility constraint. + +Keep the public return types. Changing these APIs to `Value` would preserve bad +data but would weaken the SDK and contradict the requested typed decode failure. + +## Focused tests + +### Required real-boundary coverage: `crates/client/tests/session_e2e.rs` + +Split the mock package helper so a test can choose the adapter's +`configOptions`, or add a second dedicated malformed mock package. Preserve the +existing healthy create/prompt/close test. + +Add these assertions/tests: + +1. In the existing projected-agent assertion, find the exact mock entry and + assert: + + ```rust + assert_eq!( + mock_agent.adapter_entrypoint, + "/opt/agentos/bin/mock-agent-acp" + ); + ``` + + Against the Item 34 parent this test does not compile because the public Rust + field is absent. After the fix it proves the value survived sidecar discovery, + BARE transport, and the public client mapping. + +2. Add + `session_config_decode_rejects_malformed_entry_without_shortening`. Have its + adapter return the two-entry example above, create the session, then assert + `get_session_config_options()` returns an error downcastable to: + + ```rust + ClientError::AcpDecode { context, .. } + if context == "configOptions[1]" + ``` + + Against the Item 34 parent, the same call succeeds with only the first entry. + Record that as the before-fix evidence in the tracking checklist. Close the + session and shut down the VM even after capturing the expected error. + +### Cheap deterministic unit coverage: `crates/client/src/session.rs` + +Add pure helper tests for all four response categories: + +- valid vectors preserve order and exact length; +- a malformed config entry fails at the exact index rather than shortening; +- malformed present modes/capabilities/agentInfo each return `AcpDecode`; +- omitted optional values remain `Ok(None)`; +- missing required `currentModeId`, `availableModes`, and config-option `id` + fail rather than receiving empty defaults; +- valid capability `{}` remains the documented public `None` after successful + decoding. + +The real-boundary test is still required; unit tests alone would not catch the +missing public `adapter_entrypoint` mapping. + +## Validation commands + +Run from the repository root after Item 34 is sealed and Item 35 has its own +child `jj` revision: + +```sh +cargo fmt --all -- --check +cargo check -p agentos-client +cargo test -p agentos-client --lib +cargo build -p agentos-sidecar +AGENTOS_SIDECAR_BIN="$PWD/target/debug/agentos-sidecar" \ + cargo test -p agentos-client --test session_e2e -- --nocapture +git diff --check +``` + +The e2e suite is not allowed to pass via a local skip when recording completion; +the test helper already fails if the sidecar binary is absent unless +`AGENT_OS_CLIENT_ALLOW_E2E_SKIPS` is explicitly set. + +## Dedicated Item 35 revision scope + +Expected paths in Item 35's stacked `jj` revision: + +- `crates/client/src/error.rs` +- `crates/client/src/session.rs` +- `crates/client/tests/session_e2e.rs` +- `docs/thin-client-migration.md` (before/after/completion checklist and status) +- `docs/thin-client-research/item-35.md` if research notes are retained in the + implementation stack + +Do not include protocol schemas, generated TypeScript/Rust protocol files, +sidecar implementation files, `Cargo.lock`, or TypeScript production files for +this item.

The sidecar owns discovery; Rust only copies the returned string. +- Do not convert a malformed config entry into a warning plus partial success. + The project rule is that failures propagate or are host-visible; partial + success is precisely the bug. +- Ensure the indexed context comes from the original wire order. Filtering or + sorting before decoding would make the error misleading. +- Preserve unknown extension fields where the Rust public type already has a + flattened `extra` map (`SessionMode`, `PromptCapabilities`, + `AgentCapabilities`, `AgentInfo`). Item 35 should not delete those maps. +- Keep valid `{}` capabilities -> `None`; that is a documented API normalization, + not a decode failure. Only malformed present values must fail.

Retaining a cleanup handle is not retaining +a route. + +## Exact current defects + +### `crates/agentos-sidecar-browser/src/acp_host.rs` + +- `BrowserAcpHost::execution_id` treats every entry in `executions` as active. + `abort_agent` keeps that same entry when `abort_execution` or + `release_context` fails. The retained retry handle therefore still has the + representation of a routable process. +- The real `BrowserSidecar::abort_execution` removes `ExecutionState` inside + `release_execution` before returning a worker/kernel cleanup error. On the + second `BrowserAcpHost::abort_agent` call, the sidecar reports the missing + execution as already cleaned; the ACP route is removed without reattempting + the failed worker termination. +- `finalize_session_cleanup` has the same false-success retry: its first + `release_execution` call can destroy the executor handle and fail; its second + call sees no execution and proceeds to remove the ACP route. +- `abort_agent` attempts context cleanup after execution cleanup, but has no + per-phase state. A successful context release is repeated after an execution + failure, and a successful execution cleanup is repeated after a context + failure. +- The in-progress shared-core patch now maps `BrowserSidecarError::Cleanup` to + `AcpCoreError::Cleanup` and calls `finalize_session_cleanup` before removing + the core session. The browser host still needs the non-routable phase record + described below; the new hook alone cannot recover the executor handle that + `BrowserSidecar::release_execution` destroys. + +### `crates/agentos-sidecar-browser/src/lib.rs` + +- `BrowserAcpExtension::executions` is one untyped route map. Diagnostics cannot + distinguish active routes from retained cleanup handles. +- `dispose_owners` calls `AcpCore::dispose_owner`, stringifies every error, and + returns `BrowserSidecarError::InvalidState`. Cleanup identity and the stable + `cleanup_failed` code are lost. +- `on_session_disposed` derives owners only from the route map. Once active and + cleanup routes are split, it must include both or use an explicit owner + registry. `on_vm_disposed` already receives the exact owner and should remain + the primary close path. +- The current test + `browser_acp_host_retains_route_until_abort_cleanup_can_be_retried` uses a mock + whose failed abort leaves its execution available. It does not model the real + sidecar's early `ExecutionState` removal and therefore misses the false-success + retry. + +### `crates/native-sidecar-browser/src/service.rs` + +- `release_execution` removes `ExecutionState`, `active_executions`, and signal + state before kernel reap and `terminate_worker`. Any returned cleanup error is + unretryable. +- Kernel reap and worker termination are aggregated only when both fail. A + single failure returns its raw child type, so the error shape changes with + cardinality. +- Structured release and lifecycle-event failures are logged after cleanup and + cannot be retried. If these remain best-effort diagnostics, the code must say + so explicitly and keep the existing host-visible log. If they are part of the + cleanup contract, they need progress bits like the resource phases. For Item + 36 parity, make them tracked phases. +- `abort_execution` combines kill and release failures into + `InvalidState(String)` rather than `BrowserSidecarError::Cleanup`. +- `dispose_vm` removes `VmState` before execution cleanup. Consequently + `reap_execution_kernel_process` treats the missing VM as success, worker + failures lose their handles, and a retry gets `unknown browser sidecar VM`. +- `dispose_extension_session_state` and `dispose_extension_vm_state` run every + extension but retain only `first_error`. They also have no namespace progress, + so a retry would repeat callbacks that already succeeded. +- Existing tests named `dispose_vm_drains_maps_even_when_worker_termination_fails` + and `release_execution_preserves_both_cleanup_errors_after_draining_maps` + encode handle destruction as success criteria. They must be replaced, not + preserved alongside retry state. + +### `crates/native-sidecar-browser/src/wire_dispatch.rs` + +- `close_session` retains only `first_error`, purges every VM route, removes the + session, releases its admission slot, and stores the failed attempt in terminal + history. A retry only replays the old string; no cleanup runs. +- The existing test + `browser_failed_close_replays_the_terminal_failure_and_releases_admission` + explicitly locks in that incorrect behavior. +- `dispose_vm` also purges ownership after failure and formats the extension/VM + pair ad hoc. It needs the same per-VM cleanup driver as session close. +- `purge_vm_state` currently mutates every session's `vm_ids`. Cleanup ownership + must be recorded before this route purge, and route purge must not delete the + cleanup record. +- `session_close_outcomes` must contain only final successful outcomes (or a + truly terminal result with no remaining handle). A transient cleanup failure + is not terminal history. + +## Patch checklist + +Implement in this order so each outer retry has a real inner retry to invoke. + +### 1. Make browser errors typed and deterministic + +- [x] In `agentos-sidecar-core`, add/use `AcpCoreError::Cleanup { context, + errors }` with code `cleanup_failed`. Always use it for one or more cleanup + children; do not return the raw child for a one-error aggregate. The + in-progress shared-core patch supplies the variant and code. +- [x] In `acp_host.rs::map_err`, map `BrowserSidecarError::Cleanup` recursively + to `AcpCoreError::Cleanup`. Keep `InvalidState`, `Conflict`, and + `LimitExceeded` mappings unchanged. This browser mapping is already present + in the in-progress revision. +- [ ] In `lib.rs::to_browser_error`, preserve `AcpCoreError::Cleanup` as + `BrowserSidecarError::Cleanup`; do not turn it into `InvalidState`. +- [ ] Add one helper in `native-sidecar-browser/src/service.rs`, for example + `cleanup_result(context, errors)`, that returns `Ok(())` for an empty vector + and `BrowserSidecarError::Cleanup` for every non-empty vector. +- [ ] Attach operation identity before pushing each child: execution id, VM id, + extension namespace, and phase. Preserve operation order; never sort rendered + error strings. + +Stable browser phase order: + +1. abort signal, when applicable; +2. kernel reap; +3. worker termination; +4. execution structured event; +5. execution lifecycle event; +6. context release; +7. extension namespaces in `BTreeMap` order; +8. VM ids in `BTreeSet` order; +9. session-level extension namespaces. + +### 2. Replace active executor entries with lifecycle records + +- [ ] In `service.rs`, replace + `BTreeMap` with a lifecycle value: + +```rust +enum ExecutionLifecycle { + Active(ExecutionState), + Cleaning(ExecutionCleanupState), +} + +struct ExecutionCleanupState { + execution: ExecutionState, + event_name: &'static str, + abort_signal_complete: bool, + kernel_reaped: bool, + worker_terminated: bool, + structured_event_emitted: bool, + lifecycle_event_emitted: bool, +} +``` + +- [ ] Add `begin_execution_cleanup`. It must transition `Active -> Cleaning`, + remove the id from `VmState::active_executions` and `signal_states`, and only + then perform a fallible operation. Calling it on `Cleaning` returns the + existing progress record; calling it after full removal is idempotent success. +- [ ] Make `ensure_execution`, `ensure_execution_state`, stdin, signal, kill, + poll, and event routing match only `Active`. A cleaning id must return a typed + non-active/invalid-state error and must not reach the bridge or kernel. +- [ ] Add `drive_execution_cleanup(execution_id)`. Attempt every incomplete + independent phase, set a bit only after success, and remove the lifecycle + entry only after all required bits are set. +- [ ] `abort_execution` must transition first, then drive abort signal and + release phases. If reap/termination proves the execution gone, mark a failed + abort signal superseded rather than signalling a dead worker forever. +- [ ] `release_execution` must call the same driver without an abort-signal + requirement. A retry must never repeat a successful kernel reap, worker + termination, or event phase. +- [ ] Late bridge events for a cleaning id must not reactivate it. Drop/log + terminal output for that id or route only the cleanup-relevant terminal fact. + +#### Bound and warning + +- [ ] Add + `BrowserSidecarConfig::max_pending_execution_cleanups_per_vm` with a finite + default and a public default constant. Every active execution reserves one + possible cleanup slot, so admission in `start_execution_with_options` checks + `active + cleaning` before creating a kernel process or worker. +- [ ] On exhaustion return `BrowserSidecarError::LimitExceeded` with limit + `max_pending_execution_cleanups_per_vm` and `how_to_raise` naming the exact + config field. +- [ ] Warn once at the existing 80% threshold and clear the warned bit after + usage drops below it. Store the warned bit per VM. +- [ ] Expose test-only counts for active executions and cleaning executions. + Do not count cleaning entries in `active_worker_count`. + +This reservation rule prevents permanent termination failures plus replacement +workers from growing the lifecycle map without bound. + +### 3. Make VM disposal a non-routable lifecycle + +- [ ] Add `VmLifecycle::{Active, Cleaning}` to `VmState` rather than moving a + failed VM into an unbounded second map. `ensure_vm` and every ordinary VM API + must accept only `Active`; cleanup helpers may access `Cleaning` directly. +- [ ] On the first `dispose_vm`, mark the VM cleaning before fallible work, + remove its contexts from ordinary routing, and transition every active + execution to `ExecutionLifecycle::Cleaning`. +- [ ] Drive every execution cleanup in execution-id order even after an earlier + failure. Retain the `VmState` because it owns the kernel needed for retry. +- [ ] Track the terminal VM lifecycle event as a VM cleanup phase. Remove + `VmState` only when all execution records and the VM event phase are complete. +- [ ] A second `dispose_vm` on a cleaning VM resumes incomplete phases. Ordinary + VM/execution requests during that interval must fail as non-active. +- [ ] Split diagnostics into active VM count and pending VM cleanup count. + +Do not retain a VM in an active map merely to keep its kernel. The lifecycle bit +is the enforcement check that makes the retained kernel a cleanup handle only. + +### 4. Split active ACP routes from cleanup routes + +- [ ] In `agentos-sidecar-browser/src/lib.rs`, replace the raw executions map + with a store whose values are explicit lifecycles: + +```rust +enum BrowserAcpRoute { + Active(BrowserAcpExecution), + Cleaning(BrowserAcpRouteCleanup), +} + +enum BrowserAcpCleanupKind { + Abort, + FinalizeSession, +} + +struct BrowserAcpRouteCleanup { + route: BrowserAcpExecution, + kind: BrowserAcpCleanupKind, + execution_complete: bool, + context_complete: bool, +} +``` + +- [ ] `BrowserAcpHost::execution_id` must match only `Active` and exact owner. + This immediately blocks stdin, kill, poll, and protocol routing for cleanup + entries. +- [ ] `abort_agent` and `finalize_session_cleanup` must atomically transition + the route before invoking `BrowserExtensionContext`. On retry they resume the + stored kind and incomplete bits. The shared core already marks the session + closed before retrying finalization, so it will not repeat signal/wait phases. +- [ ] Attempt execution and context phases in deterministic order and retain all + errors. Mark each successful phase independently. Remove the route only after + both are complete. +- [ ] Keep owner identity in cleaning routes so another connection/session/VM + cannot retry or observe them. +- [ ] Apply the same finite reservation used by the executor: active plus + cleaning ACP routes for one VM may not exceed + `max_pending_execution_cleanups_per_vm`. Pass the configured value into + `BrowserAcpExtension` from `browser_sidecar` and the WASM constructor. +- [ ] Extend `BrowserAcpResourceCounts` with `cleanup_process_routes` (and the + shared-core cleanup-tombstone count once added). `process_routes` must mean + active routes only. +- [ ] Update `on_session_disposed` owner discovery to include cleaning routes; + keep `on_vm_disposed`'s explicit owner as the authoritative path. +- [ ] Change `dispose_owners` to `BrowserSidecarError::Cleanup`, retaining owner + and process identity. It must cooperate with the shared core's owner cleanup + tombstones rather than calling `take_owner_state` a second time and declaring + success. + +### 5. Track extension namespace progress + +- [ ] Add `BrowserSidecar::extension_namespaces()` returning the deterministic + registered namespace set. +- [ ] Change `dispose_extension_vm_state` and + `dispose_extension_session_state` to accept a mutable set of pending + namespaces, or add a small exported `BrowserExtensionCleanupProgress` value. +- [ ] Snapshot namespaces when cleanup ownership transitions. Invoke every + pending namespace in `BTreeMap` order; remove a namespace from progress only + after its callback succeeds. +- [ ] Aggregate every failed namespace with `BrowserSidecarError::Cleanup`. + Successful sibling callbacks must not run again on retry. +- [ ] Reinsert each temporarily removed extension in the registry before + handling its result, exactly as the current code does. + +This progress belongs to the cleanup transaction, not to the extension object: +the wire owner decides when a VM/session is no longer routable, while each +extension owns only its callback implementation. + +### 6. Keep wire close ownership until cleanup finishes + +- [ ] Replace `BrowserSessionState { connection_id, vm_ids }` with an explicit + lifecycle: + +```rust +struct BrowserSessionState { + connection_id: String, + lifecycle: BrowserSessionLifecycle, +} + +enum BrowserSessionLifecycle { + Active { + vm_ids: BTreeSet, + vm_cleanups: BTreeMap, + }, + Closing { + vm_cleanups: BTreeMap, + pending_session_extensions: BTreeSet, + }, +} + +struct BrowserVmCleanupProgress { + pending_extensions: BTreeSet, + vm_complete: bool, +} +``` + +- [ ] On the first `close_session`, validate exact connection ownership, move + every active VM into cleanup progress, set `Closing`, and purge ordinary VM, + process, cron, capture, and pending-event routes before fallible cleanup. +- [ ] Keep the session id in `BrowserConnectionState::sessions` while closing. + Therefore `max_sessions_per_connection` bounds active plus closing sessions + and a permanent cleanup failure cannot release admission for unlimited new + sessions. +- [ ] Make `owned_vm_id`, `create_vm`, extension routing, cron routing, and every + ordinary operation require `BrowserSessionLifecycle::Active` plus an active + VM id. A closing session is cleanup-only. +- [ ] Add one `drive_vm_cleanup` used by explicit `dispose_vm` and session close. + It resumes pending extension namespaces and `BrowserSidecar::dispose_vm`, marks + successful phases, and retains all failed phases. +- [ ] Session close must drive all VM records even after failures, then drive all + pending session-extension namespaces. Return one deterministic aggregate for + the current attempt. +- [ ] On failure, leave the session `Closing`, retain its connection ownership, + and do not write `session_close_outcomes`. +- [ ] On full success, remove the session and connection admission entry, then + record only the successful terminal outcome in bounded close history. +- [ ] A close retry by the same connection resumes incomplete phases. A retry by + another connection remains `ownership_mismatch`.

The current tree has already fixed the +largest ordering problem described in `item-36.md`: native terminal and +extension-resource cleanup now runs from +`AcpHost::release_agent_route`/`NativeCoreCommand::ReleaseAgentRoute`, and +`AcpCore::close_session` removes its authoritative session only after that hook +succeeds. Do **not** add a second finalization hook or restore a post-dispatch +cleanup block. + +Three native problems remain: + +1. Cleanup loops use `first_error`, `?`, or an `Execution(String)` join, so a + caller sees only a prefix of the failures. Native cleanup needs one stable, + typed, operation-ordered aggregate. +2. ACP route finalization does not retain per-phase progress, and + `ExtensionHost::dispose_session_resources` removes its only retry record + before fallible cleanup. A failed close can therefore repeat completed work, + skip later work, or turn the retry into an apparent no-op. +3. stdio runs disconnect cleanup only after a clean event-loop break and then + discards `remove_connection` errors.

If a later resource cleanup removes the VM but reports a +post-detach error, the next call repeats `stop_buffering_process_output`; that +method calls `require_owned_vm`, so the retry can now fail forever even though +the output phase already completed. Persisted phase bits are required, not just +moving the `core_processes.remove` line. + +## Exact patch checklist + +### A. Add the native and shared-core aggregate variants + +- [ ] In `crates/native-sidecar/src/state.rs`, add: + + ```rust + Cleanup { + context: &'static str, + errors: Vec, + }, + ``` + + Match the existing `BrowserSidecarError::Cleanup` display contract: render + `context`, followed by `; cleanup error N: ...` in vector order. The vector + must be non-empty. +- [ ] Add a private native helper such as + `cleanup_result(context, errors) -> Result<(), SidecarError>`. It returns + `Ok(())` only for an empty vector and returns `Cleanup` for **one or more** + children. Never change error shape based on cardinality. +- [ ] When a child error does not already name its resource, wrap it before + adding it so the rendered child names the phase and identity: terminal id, + process id, VM id, extension namespace, or session id. +- [ ] Map `SidecarError::Cleanup` to `cleanup_failed` in + `crates/native-sidecar/src/execution.rs::error_code` and + `crates/agentos-sidecar/src/acp_extension.rs::error_code`. +- [ ] Add `AcpCoreError::Cleanup { context: &'static str, errors: + Vec }` in `crates/agentos-sidecar-core/src/lib.rs`, with the same + ordered display and code `cleanup_failed`. +- [ ] Update `acp_extension.rs::sidecar_to_core_error` to recursively preserve a + native `Cleanup` aggregate as `AcpCoreError::Cleanup`; do not flatten it to + `Execution(String)`. +- [ ] Let compiler exhaustiveness identify remaining native maps, then verify + every map preserves `cleanup_failed`; do not bulk-convert cleanup to + `execution_error`. + +### B. Make native ACP route finalization phase-aware + +- [ ] Extend `NativeCoreProcess` in `acp_extension.rs` with private cleanup + progress, initialized false when the process route is inserted: + + ```rust + struct NativeRouteCleanupProgress { + output_buffer_stopped: bool, + terminals_cleaned: bool, + session_resources_disposed: bool, + } + ``` + + A process without a bound ACP `session_id` treats the last two phases as + already complete. +- [ ] Keep the existing `ReleaseAgentRoute` broker command and + `AcpHost::release_agent_route` hook. Update their comments to call it orderly + host finalization, because native cleanup now legitimately lives there. +- [ ] Refactor `release_native_agent_route` to clone the route/progress before + awaits and commit each successful phase back to the exact `(owner_id, + process_id)` entry. Never hold the `tokio::Mutex` guard across an await. +- [ ] Attempt output-buffer cleanup and every terminal cleanup that is safe in + the current attempt; collect both errors in phase order. Mark each phase only + after it returns `Ok`. +- [ ] Treat extension resource disposal as dependent on output/terminal cleanup + when it may dispose their VM. Do not destroy the VM while a still-retryable + output/terminal phase needs it. Once prerequisites are complete, drive + resource disposal and record its error after the earlier phase errors. +- [ ] On a resource-disposal error, retain the process route and its completed + phase bits. A retry skips completed output/terminal work and re-enters only + resource disposal. +- [ ] Remove `core_processes[route_key]` only when all applicable bits are true. + The existing shared core will then remove its ACP session. An aggregate error + leaves both records present but the close remains fail-closed because the core + already removes pending prompts at close start. +- [ ] Convert `cleanup_session_terminals` from `Execution(errors.join("; "))` + to `SidecarError::Cleanup`. Keep terminal-id order and kill-before-output order. +- [ ] In `NativeCoreCommand::AbortAgent`, aggregate kill and route-finalization + errors rather than formatting them into `AcpCoreError::Execution`. Retain the + route whenever finalization is incomplete. + +### C. Preserve `ExtensionSessionResources` until cleanup completes + +- [ ] In `service.rs::dispose_session_resources`, read and clone the sorted + `process_ids`/`vm_ids`; do not call `extension_sessions.remove(&key)` before + I/O. +- [ ] Attempt every process id in `BTreeSet` order. Process absence is success. + Remove an id from the live record after absence or a successful termination + request; retain it after an error. Record errors with the process id. +- [ ] Do not begin destructive VM cleanup while failed process ids remain for + that resource record. On a later retry, process cleanup runs first again. +- [ ] Attempt every eligible VM id in `BTreeSet` order. VM absence is success. + After `dispose_vm_internal` returns, remove the id when the VM is now absent, + even if teardown returned an error: post-detach teardown cannot be retried and + retaining that id manufactures an endless ownership error. Retain the id only + if the VM is still present. +- [ ] Be robust to `dispose_vm_internal` calling `prune_extension_vm_resource` + and deleting/mutating the same record. Re-fetch `extension_sessions.get_mut` + after each await; absence means the sidecar already reclaimed the handle. +- [ ] Remove the whole record only when both sets are empty. Return the current + attempt's ordered aggregate even if every handle became irreversibly absent; + the next call then sees no record, succeeds, and lets ACP finalization finish. +- [ ] Keep event ordering deterministic. Do not lose events from successful VM + cleanups merely because a sibling failed; if the current `Result, _>` + signature cannot carry both, introduce an internal outcome containing + `events` plus `errors` and convert only at the wire boundary. + +### D. Aggregate native service and VM disposal + +- [ ] Replace `first_error` in `remove_connection`, `dispose_session`, and + `dispose_extension_session_state` with ordered vectors and the common helper. + Preserve ordering: connection session ids; session VM ids; then extension + namespaces. +- [ ] Collect `(namespace, Arc)` rather than values alone in + `dispose_extension_session_state`, so each child names the failing namespace. +- [ ] For requested wire close, add a non-routable cleanup lifecycle/progress to + `SessionState` (in `state.rs`). `require_owned_session` and VM creation/runtime + requests must reject a disposing session; `close_session_request` alone may + re-enter its cleanup driver. +- [ ] Retain which extension namespaces completed successfully, so a retry does + not call successful hooks twice. Existing `session.vm_ids` is the pending VM + set because `reclaim_vm_tracking` removes a detached VM id. +- [ ] Remove the session, connection membership, and push `disposed_sessions` + only after a requested cleanup attempt completes without errors. If an + irreversible post-detach error emptied all pending phases, return the failure + once; the next close finalizes the empty cleanup state. +- [ ] In `close_session_request`, record `SessionCloseOutcome` only after final + success. Never store `error_message: Some(...)`; a failure is retryable, not a + terminal outcome. Second close retries; third close replays the successful + bounded history entry. +- [ ] For `DisposeReason::ConnectionClosed`, attempt every incomplete phase once, + aggregate failures, then remove routable connection/session state. There is no + caller retry. If a concrete resource handle must survive for retry, move it to + a bounded non-routable cleanup registry; do not leave an active session owned + by a removed connection. +- [ ] In `vm.rs::terminate_vm_processes`, collect failures for every SIGTERM + target, the first wait, every remaining SIGKILL target, the second wait, and + the final active-process check. Continue whenever the next operation is + independent and keep process-id/phase order. +- [ ] In `finish_vm_teardown`, run independent phases even after an earlier + failure: snapshot/encode, lifecycle emission, kernel dispose, snapshot flush + when a snapshot exists, and permission clearing. Aggregate in that order. +- [ ] In `dispose_vm_internal`, aggregate mount shutdown, process termination, + teardown, cwd removal, and staging-root removal after unconditional + `reclaim_vm_tracking`. Treat `NotFound` directory removal as success; include + other I/O errors with the exact path. +- [ ] Change `shutdown_configured_mounts` so continue-on-error mode collects + unmount failures instead of returning `Ok(())`. Always emit a `tracing::error!` + containing VM id, guest path, plugin id, phase, errno, and error. If the + structured failure event also cannot be emitted, log that second failure; + remove the current discarded `let _ = emit_structured_event(...)`. + +### E. Make stdio cleanup unconditional and visible + +- [ ] In `stdio.rs::run_async`, execute the event loop inside an async block that + produces `run_result`. After the block finishes for EOF **or any error**, call + `cleanup_connections`, then return the original `run_result`. Cleanup must not + replace a more useful transport/dispatch error. +- [ ] In `cleanup_connections`, retain `BTreeSet` connection order and match each + `remove_connection` result. For every failure, emit: + + ```rust + tracing::error!( + target: "agentos_native_sidecar::stdio", + connection_id, + error_code = crate::execution::error_code(&error), + error = %error, + "failed to clean up disconnected native-sidecar connection", + ); + ``` + +- [ ] Continue to every connection after a failure, then untrack every disposed + session. Remove `let _ = sidecar.remove_connection(...)`. +- [ ] Do not attempt to send cleanup failure frames to stdout after disconnect; + stderr/tracing is the authoritative host-visible path. + +## Focused before/after tests + +Add the named tests before changing behavior and record the old outcomes in the +tracker. All assertions must inspect the typed variants and vector order, not +only substring presence. + +### `crates/native-sidecar/src/state.rs` / `execution.rs` + +- [ ] `cleanup_error_code_and_display_are_stable_and_ordered`: construct one and + two-child native aggregates; both have `cleanup_failed`, both retain the + `Cleanup` shape, and display preserves insertion order. + +### `crates/agentos-sidecar/src/acp_extension.rs` + +- [ ] Extract a small fakeable cleanup driver around native route phases and add + `native_route_finalization_retries_only_incomplete_phases`. First attempt: + output succeeds, terminal succeeds, resources fail once. Assert the route and + core session remain. Second attempt calls only resources and succeeds; route + and core session disappear. Third close is idempotent and calls no phase. +- [ ] `native_route_finalization_preserves_phase_error_order`: fail output and + two terminal actions in one safe attempt. Assert one `AcpCoreError::Cleanup` + with output first, terminal ids in `BTreeMap` order, and kill before output for + one terminal. Assert destructive VM/resource cleanup was deferred while its + prerequisites remained incomplete. +- [ ] `native_abort_preserves_kill_and_finalization_failures`: fail both branches + and assert one ordered aggregate, with the route retained for retry. + +### `crates/native-sidecar/src/service.rs` + +- [ ] Extend the existing `dispose_lifecycle_tests::RecordingExtension` into a + programmable extension with namespace, call count, and failures remaining. +- [ ] `dispose_extension_session_state_aggregates_namespace_order_and_retries_only_failures`: + register two failing extensions in reverse insertion order, verify namespace + order in the aggregate, clear failures, and verify only unfinished namespaces + are called again. +- [ ] `extension_resource_cleanup_retains_failed_ids_and_retries_only_incomplete_ids`: + use a local fake cleanup seam for two process ids and two VM ids. Fail the + second of each once. Verify every eligible sibling is attempted, successes + are removed, failures remain, and retry calls only retained ids. +- [ ] `extension_resource_cleanup_drops_post_detach_vm_handle_but_reports_current_error`: + make VM disposal detach then fail. The first result contains the VM error and + the id is absent; retry succeeds without an ownership error. +- [ ] Replace the current + `dispose_session_reclaims_session_even_when_a_vm_dispose_fails` expectation. + Requested cleanup failure must retain a **non-routable** cleanup session; + successful retry removes it. ConnectionClosed still detaches it after the + exhaustive attempt. +- [ ] `close_session_request_retries_cleanup_failure_before_recording_terminal_success`: + a one-shot extension failure rejects the first close with `cleanup_failed`, + leaves no terminal history entry, succeeds on the second close, and replays + success without new cleanup on the third. +- [ ] `remove_connection_aggregates_every_session_failure_before_detach`: seed + two sessions with ordered failing extensions/VM identities. Assert all + sentinels occur once in session/resource order and connection/session routing + state is gone afterward. + +### `crates/native-sidecar/src/vm.rs` + +- [ ] Add a small teardown-operations fake rather than environment variables. + `dispose_vm_aggregates_process_teardown_mount_and_filesystem_failures` injects + at least one failure in each independent phase and asserts exact vector order, + one occurrence each, VM detachment, and zero per-VM tracking entries. +- [ ] `mount_shutdown_logs_primary_and_event_delivery_failure` captures tracing + and verifies VM/plugin/guest-path/errno identity even when structured-event + delivery also fails. + +### `crates/native-sidecar/src/stdio.rs` + +- [ ] Add a tiny `tracing_subscriber::fmt` test writer backed by + `Arc>>` (the dependency already exists). +- [ ] `cleanup_connections_logs_connection_id_code_and_every_child`: seed an + authenticated connection whose two session cleanup hooks fail. Invoke + `cleanup_connections`; assert the captured stderr contains the connection id, + `cleanup_failed`, both sentinels in deterministic order, and no live + connection/session route. +- [ ] `event_loop_error_still_runs_disconnect_cleanup`: factor the event-loop + body so a synthetic writer/read error can terminate it, then assert the same + cleanup hook ran before `run_async` returned the original error. + +## Validation and revision boundary + +Expected native implementation paths: + +- `crates/agentos-sidecar-core/src/lib.rs` +- `crates/agentos-sidecar-core/src/host.rs` (comment only unless the existing + hook contract genuinely cannot carry finalization) +- `crates/agentos-sidecar/src/acp_extension.rs` +- `crates/native-sidecar/src/state.rs` +- `crates/native-sidecar/src/execution.rs` +- `crates/native-sidecar/src/service.rs` +- `crates/native-sidecar/src/vm.rs` +- `crates/native-sidecar/src/stdio.rs` +- their focused native tests + +Do not touch client packages.

If host cleanup fails, a retry sees + `no pending ACP interaction` and the cleanup handle is lost. The existing + regression `resumable_abort_removes_pending_state_before_cleanup_error_propagates` + at `engine.rs:5805-5847` proves this behavior. +2. `abort_agent_for_cleanup` at `engine.rs:3670-3678` only warns. Its create, + resume, prompt, and restart callers return the primary error while silently + abandoning a failed host cleanup. +3. Orderly close calls the narrow `AcpHost::release_agent_route` hook. Native's + implementation in `crates/agentos-sidecar/src/acp_extension.rs:1223-1239` + runs output, terminal, and extension-session cleanup sequentially with `?`. + A first failure skips later phases. +4. Native `dispose_session_resources` at + `crates/native-sidecar/src/service.rs:3879-3930` removes the complete + `ExtensionSessionResources` record before killing its process/VM resources. + Any failure leaves nothing for a close retry. +5. Shared `AcpCoreError` has no aggregate cleanup variant, so wrappers flatten + multiple failures into `Execution(String)` or `InvalidState(String)`. + +## Required shared-core data model + +Add a bounded, non-routable cleanup registry to `AcpCore`: + +```rust +type CleanupKey = (String, String); // exact (owner_id, process_id) + +struct PendingCleanup { + session_id: Option, + action: CleanupAction, + completion: CleanupCompletion, +} + +enum CleanupAction { + AbortAgent, + FinalizeSession { session_id: String }, +} + +enum CleanupCompletion { + Response(AcpResponse), + Error(AcpCoreError), + RestartPrompt { + pending: PendingPrompt, + exit_code: Option, + }, +} +``` + +Use `BTreeMap` plus a bounded secondary +`BTreeMap<(owner_id, session_id), process_id>` only for close retry lookup. +Both maps contain the same bounded records; the second map is an index, not +another lifecycle state machine. + +The tombstone must not appear in `pending_response`, accept agent output, accept +session requests, or be returned by `list_sessions`. A wrong owner receives the +same `no pending ACP interaction` response as an absent process. Store the +original completion; a retry may not change it by supplying a different abort +reason. + +### Bound and admission invariant + +Add a sidecar-owned per-owner route/cleanup limit, defaulted in the shared core +and overridable by the embedding sidecar, with APIs analogous to the event +limit: + +```rust +AcpCore::with_process_cleanup_limit(limit) +set_process_cleanup_limit(owner_id, limit) +``` + +Count unique process IDs across live sessions, all five pending maps, and cleanup +tombstones. Enforce the limit before every operation that can add a new process +ID (`begin_create_session`, `begin_resume_session`, and adapter restart spawn). +A prompt or close reuses its session process ID and consumes no extra slot. + +This reservation is critical: a failed process route replaces one already +counted active/pending route with one tombstone, so recording retry state can +never itself fail at cleanup time. Do not check capacity only after +`abort_agent` fails. + +Use `AcpCoreError::LimitExceeded` with the exact observed count, limit, and +instruction to raise the sidecar ACP process-cleanup limit. Warn once per owner +near the threshold. Refuse zero or lowering below current usage. Remove owner +limit/warning state only when owner state is fully dropped. + +## Exact transition helpers + +Implement three helpers in `engine.rs`: + +```rust +fn stage_cleanup(&mut self, key: CleanupKey, cleanup: PendingCleanup); + +fn drive_process_cleanup( + &mut self, + host: &mut H, + owner_id: &str, + process_id: &str, +) -> Result; + +fn drive_session_cleanup( + &mut self, + host: &mut H, + owner_id: &str, + session_id: &str, +) -> Result; +``` + +`drive_*` must: + +1. verify exact ownership before invoking the host; +2. call only the tombstone's stored action; +3. retain the tombstone unchanged on error; +4. remove both indices only after host success; and +5. then deliver the stored response/error or run the stored restart continuation. + +Remove the tombstone before running a restart continuation so a new failure is +recorded by the normal restart path, not by mutating the old tombstone. If the +continuation returns an error, preserve both the completed cleanup result and +that new error normally. + +## `abort_pending` patch checklist + +- At the very start of `abort_pending`, check `(owner_id, process_id)` in the + cleanup registry and call `drive_process_cleanup`. This is the retry path. +- Replace `remove_pending_state` with `take_pending_state`, returning an enum + containing the moved pending value. Apply session mutations (closed flag, + preamble restore, or session removal) explicitly for that variant. +- Construct the final `AcpResponse` before host cleanup and store it in + `CleanupCompletion::Response`. +- Insert the tombstone **before** calling `host.abort_agent`; then call + `drive_process_cleanup` immediately for the first attempt. +- For `AgentExited` during a prompt, store the moved `PendingPrompt` and exit + code in `RestartPrompt`. Only begin adapter restart after abort succeeds. +- For a failed replacement restart, retain the moved `PendingRestart` until + abort succeeds; do not render cleanup failure into the restart message and + discard the handle. +- For pending-close `DriverFailed`/`CallerCancelled`, mark the session closed, + stage `AbortAgent`, and remove the session only after abort succeeds. +- A tombstoned process is absent from every pending map immediately, so + `feed_agent_output` and `pending_response` reject it. + +Replace `abort_agent_for_cleanup` with a result-bearing staging helper. Every +current call site must return `AcpCoreError::Cleanup` containing the primary +error first and the abort failure second, while leaving a retry tombstone. No +empty `catch`, warning-only result, or string concatenation remains. + +## Orderly session finalization checklist + +Replace the host seam in `crates/agentos-sidecar-core/src/host.rs:105-110`: + +```rust +fn finalize_session_cleanup( + &mut self, + session_id: &str, + process_id: &str, +) -> Result<(), AcpCoreError>; +``` + +The hook is idempotent and means "finish every host-owned resource for this +closed ACP session," not merely "remove one process route." + +In both blocking `close_session` and `finish_resumable_close`: + +- check the session cleanup index first and retry it; +- after signal/wait reaches terminal, mark the session record `closed = true`; +- stage `FinalizeSession` with the exact successful close response before the + host call; +- call `drive_session_cleanup`; +- keep the closed session record plus tombstone on failure; and +- remove the session only after finalization succeeds. + +Filter cleanup-pending/closed records from `list_sessions`, and reject prompt or +config mutation on them. `get_session_state` may report the retained closed +state for diagnostics. A repeated `close_session` must find and drive the +tombstone rather than returning the normal absent-session idempotent success. + +This also prevents retry from repeating SIGTERM/SIGKILL: only the finalization +action is replayed. + +## Aggregate error shape + +Add to `AcpCoreError`: + +```rust +Cleanup { + context: &'static str, + errors: Vec, +} +``` + +Its code is `cleanup_failed`. Require a non-empty vector, preserve operation +order, and format numbered children without flattening their codes internally. +Update native/browser host-to-core maps to preserve `Cleanup`; do not convert it +to `Execution` or `InvalidState`. + +Stable child order for native finalization is: + +1. adapter output-route cleanup; +2. terminal IDs in `BTreeMap` order, kill before output cleanup; +3. extension process IDs in `BTreeSet` order; +4. extension VM IDs in `BTreeSet` order; and +5. core-process metadata removal last, only if all prior phases succeeded. + +## Native finalization implementation + +Rename `NativeCoreCommand::ReleaseAgentRoute` to `FinalizeSessionCleanup` and +carry both IDs. `NativeCoreHost` forwards the new host method. + +Refactor `release_native_agent_route` into a finalizer that attempts all three +independent phases even when one fails: + +- `stop_buffering_process_output(process_id)`; +- `cleanup_session_terminals(session_id)`; and +- `dispose_session_resources_wire(session_id)`. + +Aggregate every failure. Retain `core_processes[(owner, process)]` until all +phases succeed. Each underlying phase must be idempotent. + +In `NativeSidecar::dispose_session_resources`, do not remove +`ExtensionSessionResources` up front. Snapshot sorted IDs, attempt all of them, +and remove each ID from the retained record only when that resource succeeded or +is authoritatively already absent. Remove the record when both sets are empty. +An error from one process/VM must not skip later resources. + +Browser `finalize_session_cleanup` should drive its existing execution/context +cleanup and retain failed non-routable worker cleanup state as described by the +main Item 36 note; it must be idempotent for a missing completed route. + +## Focused test checklist + +Replace the vulnerable abort regression at `engine.rs:5805-5847` with assertions +that: + +- first abort failure returns `cleanup_failed` and retains one tombstone; +- active pending count is zero and output is rejected; +- wrong-owner retry neither invokes the host nor reveals the tombstone; +- exact-owner retry calls abort again, returns the originally stored terminal + response, and removes the tombstone; and +- a third retry is the normal unknown-pending error. + +Add these shared-core tests: + +- cleanup limit `1`: one failed cleanup blocks a new process admission with a + typed/how-to-raise error; successful retry frees the slot; +- a prompt-abort cleanup retry restores its preamble once and starts at most one + replacement adapter; +- cleanup retry cannot change terminal response by changing abort reason; +- close finalizer fails once: session is closed/non-routable, absent from list, + no signal phase repeats, retry calls only finalization, then removes state; +- finalize failure plus a second child failure returns ordered + `Cleanup { errors: [...] }`; and +- owner disposal includes cleanup tombstones, tries all in sorted process order, + and never exposes them to another owner. + +Update native tests to inject independent failures in output cleanup, terminal +cleanup, extension process cleanup, and extension VM cleanup.

This note does not change `docs/thin-client-migration.md` +or any production/test implementation. + +## Outcome + +Item 36 should be implemented as a sidecar-only error-propagation and cleanup +transaction change. No TypeScript or Rust client behavior is needed. + +The discovery half is nearly implemented already by the in-progress Item 34 +ACP convergence: the shared core now preserves errors returned by the host's +projected-agent source. Item 36 still needs focused regressions that distinguish +an authoritative projected-state failure from a valid empty catalog or a real +unknown-agent result. + +The cleanup half is not complete. There are four related defects: + +1. Native and browser session/extension cleanup loops attempt multiple actions + but retain only `first_error`, hiding every later failure. +2. Native ACP close removes the shared-core session before native terminal and + extension-resource cleanup runs. If that cleanup fails, retry is reported as + an idempotent success and the cleanup is not retried. +3. Browser execution cleanup removes the only worker handle before fallible + kernel/worker cleanup. A failed termination is reported once but cannot be + retried; the ACP route has also already been removed. +4. Native stdio connection teardown discards the result of + `remove_connection`, so all aggregated disconnect-cleanup failures can still + disappear without a caller response or a log. + +The implementation should make cleanup state non-routable immediately, retain +only the opaque cleanup handle/phases needed for retry, try every independent +cleanup action in deterministic order, and return one typed aggregate. When no +request remains to receive the aggregate (stdio disconnect/process shutdown), +log it at the failure site. + +## Current code map + +Line numbers below are from the current Item 34 working copy and may move.

It aggregates the two immediate failures, but retry sees no execution and returns success without reattempting termination. | +| `BrowserSidecar::dispose_vm` (around lines 1829-1880) | Correctly attempts all active executions, but it depends on early removal in `release_execution`; a failure drains the active map and loses the handle. It also returns a raw error for one failure and `Cleanup` for two, so cleanup error shape changes with cardinality. | +| `crates/native-sidecar-browser/src/wire_dispatch.rs::close_session` (around lines 1382-1446) | Keeps only the first extension/VM/session error, purges ownership state, removes the session, and records the failure as terminal. Retry only replays that first string. | +| `BrowserWireDispatcher::dispose_vm` (around lines 1720-1769) | Correctly observes both extension and VM failures, but formats them ad hoc; it should use the same typed aggregate helper. | + +`BrowserSidecarError::Cleanup { context, errors }` already exists and its +`Display` implementation preserves vector order. Reuse it rather than creating +another browser cleanup string format. + +## Recommended implementation + +### 1. Add one typed aggregate shape per error layer + +Add `Cleanup { context: &'static str, errors: Vec<...> }` to native +`SidecarError` and shared `AcpCoreError`, matching the existing browser error. +The vector must be non-empty and kept in operation order. Add a small helper at +each layer that returns `Ok(())` for an empty vector and always returns the +`Cleanup` variant for one or more errors; do not return a raw child for the +single-error case. + +Recommended stable codes: + +- `AcpCoreError::Cleanup` -> ACP code `cleanup_failed`. +- native `SidecarError::Cleanup` -> native error code `cleanup_failed`. +- `BrowserSidecarError::Cleanup` already maps to browser wire code + `cleanup_failed`. +- wire-session close may retain its operation code `close_session_failed`, with + the nested aggregate in the message/details. + +Update these exhaustive maps: + +- `crates/agentos-sidecar-core/src/lib.rs::{AcpCoreError::code, Display}`. +- `crates/agentos-sidecar/src/acp_extension.rs::{sidecar_to_core_error,error_code}`. +- `crates/native-sidecar/src/execution.rs::error_code` and any exhaustive native + error matches found by `rg 'match .*error|SidecarError::'`. +- `crates/agentos-sidecar-browser/src/acp_host.rs::map_err` should map browser + `Cleanup` to shared-core `Cleanup`, not generic `Execution`. +- `BrowserAcpExtension::dispose_owners` should return + `BrowserSidecarError::Cleanup`, retaining the child errors rather than their + strings. + +Keep operation identity in each child message, for example: + +```text +failed to clean up native ACP session "s1"; +cleanup error 1: terminal "term-a" kill: ...; +cleanup error 2: terminal "term-b" output cleanup: ...; +cleanup error 3: extension session resources: ... +``` + +Use stable ordering: + +1. adapter close/signal/wait; +2. terminal ids in `BTreeMap` order, kill before output cleanup; +3. extension process ids in `BTreeSet` order; +4. extension VM ids in `BTreeSet` order; +5. extension namespaces in `BTreeMap` order; +6. session VM ids and session ids in their existing `BTreeSet` order. + +Never sort rendered error strings; sort/iterate resource identities and preserve +the semantic phase ordering above. + +### 2. Move native post-close cleanup into the shared core host transaction + +Replace the narrow host hook +`AcpHost::release_agent_route(process_id)` with an idempotent finalization hook +that receives both identities, for example: + +```rust +fn finalize_session_cleanup( + &mut self, + session_id: &str, + process_id: &str, +) -> Result<(), AcpCoreError>; +``` + +`AcpCore::close_session` should call this hook on every owned close, including an +adapter already marked closed, and only then remove the session. A hook failure +therefore leaves the authoritative core record in place for retry. The browser +implementation removes the now-inactive ACP route idempotently. The native +implementation sends a new broker command carrying `session_id` and +`process_id`; its async handler: + +1. runs `cleanup_session_terminals`; +2. always runs `dispose_session_resources_wire`, even if step 1 failed; +3. aggregates both results; +4. removes matching `core_processes` metadata only after all cleanup succeeds. + +Delete the post-core close block in `dispatch_shared_core` once this is in the +host hook. Leaving both creates a double-cleanup path and preserves the retry +bug. + +### 3. Preserve native resource retry state + +Refactor `ExtensionHost::dispose_session_resources` so it does not remove the +entire `ExtensionSessionResources` record before work: + +1. Clone the sorted process/VM ids to drive cleanup without holding a mutable + map borrow across async calls. +2. Attempt every process and VM. +3. Remove an individual id from the retained record when that resource is + confirmed absent or cleanup succeeds. +4. If a VM teardown returned an error but the VM was nevertheless detached, + remove that VM id (there is nothing left to retry) and retain the error in + the aggregate. +5. Remove the record only when both retained sets are empty. + +This makes a native ACP close retry meaningful. It also prevents one failed +terminal/process cleanup from hiding later failures. + +For wire-session close, do not put a failed attempt in terminal close history +or remove the session until retryable cleanup is complete. If a particular +resource is irreversibly gone despite reporting an error, mark that phase done, +retain/log the error for the current attempt, and let the next close finish the +remaining phases. Only a successful terminal result belongs in the bounded +close history. + +Connection loss has no caller retry. Attempt all retained cleanup once more, +log the typed aggregate with exact connection/session ownership, then detach +routable state. If handles must outlive the connection for background retry, +store them in a bounded, non-routable sidecar cleanup registry and drain that +registry during sidecar shutdown. + +### 4. Preserve browser cleanup handles without preserving routes + +Do not keep a failed execution in the active/routable ACP map. Add a separate +sidecar-owned cleanup record (or an explicit non-routable lifecycle state) that +retains: + +- VM id, execution id, worker id, runtime, and kernel pid; +- whether kernel reap completed; +- whether worker termination completed; +- whether structured and lifecycle cleanup events completed; +- the stable cleanup event name. + +`release_execution` should atomically move an active execution into this cleanup +state before fallible work, attempt every incomplete phase, mark successful +phases, and remove the cleanup record only when all phases finish. A retry calls +the same phase driver. `ensure_execution`, stdin, signal, and polling APIs must +reject a cleanup-state id as non-active so retaining the handle cannot make the +execution routable again. + +The cleanup registry must be bounded and must warn near capacity. The cleanest +bound is a `BrowserSidecarConfig` per-VM pending-cleanup limit enforced at +execution admission; the `LimitExceeded` error should name +`max_pending_execution_cleanups_per_vm` and how to raise it. Count active plus +cleanup-state executions for admission so repeated permanent termination +failures cannot grow the registry by starting replacements. + +`abort_execution`, `dispose_vm`, and session close should drive pending cleanup +records too. If VM state has already been detached, kernel cleanup is complete +by destruction but the worker handle still must be retried. A VM cleanup +tombstone is also needed when the only failed phase is terminal event emission; +otherwise an empty VM has no execution record on which to retain that failure. + +Browser wire session close must keep the live session/VM cleanup ownership until +all extension and VM cleanup phases finish. Do not record a failed attempt as a +terminal close outcome. Record and replay only the final successful close (or a +true terminal outcome that has no remaining cleanup handle). + +### 5. Replace warning-only shared-core abort cleanup + +Change `abort_agent_for_cleanup` to return an error aggregate instead of `()`. +At every call site, combine the primary failure and abort failure in fixed order. +For resumable paths, retain a bounded owner/process cleanup tombstone when host +abort fails. A subsequent `AcpAbortPendingRequest` for that exact owner/process +must retry host cleanup and never expose the tombstone to another owner. + +The tombstone is not an active interaction: it must not accept output or session +requests. It exists only to retain the host cleanup correlation and the terminal +response that should be returned when retry succeeds. Include it in diagnostics +as `pending_cleanup_count` so wrapper tests can prove zero residual resources. + +Use a sidecar-resolved bound with a near-capacity warning and typed +`limit_exceeded` admission failure. Do not introduce an unbounded cleanup map. + +## Focused tests + +### Before-behavior evidence + +Add named regression tests before changing the implementation, and run them +against Item 33 (`066f6b51`) or encode the old helper behavior in a focused +fixture. The tracking row should name the tests and record the observed old +outcome. + +1. In `crates/agentos-sidecar/tests/acp_extension.rs`, add + `acp_list_agents_preserves_projected_state_failure`. Dispatch a valid + `AcpListAgentsRequest` with session ownership but no VM scope. The projected + source returns the exact ownership error. At Item 33 the request succeeds + with `agents: []`; after the fix it must be `AcpErrorResponse` with + `invalid_state` and the original "requires VM ownership" message. +2. In `crates/agentos-sidecar-core/src/engine.rs`, use a host whose + `resolve_projected_agent` and `list_projected_agents` return distinct sentinel + errors. Assert create/resume and list return those exact code/message pairs, + never unknown-agent/empty. +3. Extend the existing native service disposal test fixtures with two failing + extensions and two failing VM/resource identities. The pre-fix result contains + only the first sentinel; after the fix it contains every sentinel once in the + documented order. +4. Replace/rename the current core test + `resumable_abort_removes_pending_state_before_cleanup_error_propagates`. + Before: cleanup failure removes pending state and retry is `invalid_state`. + After: pending interaction is non-routable, a cleanup tombstone remains, + exact-owner retry reattempts abort, and diagnostics return to zero. +5. Add a native ACP close test where final session cleanup fails once and then + succeeds. The first close must return `cleanup_failed`; state/cleanup + correlation remains. The second close must reattempt the failing phase and + return closed; a third close is idempotent and performs no cleanup. +6. In `crates/native-sidecar-browser/src/service.rs`, update the existing tests + `release_execution_terminates_worker_after_kernel_cleanup_failure` and + `release_execution_preserves_both_cleanup_errors_after_draining_maps`. + Assert the active route count is zero but a non-routable cleanup record exists, + both sentinels are present in order, retry calls only incomplete phases, and + cleanup count reaches zero. +7. In `crates/native-sidecar-browser/src/wire_dispatch.rs`, register two failing + extensions and a bridge/kernel cleanup failure. Assert close returns one + deterministic aggregate containing all failures, retains retry ownership, + and a subsequent close completes after failures are cleared. +8. In `crates/agentos-sidecar/tests/acp_wrapper_conformance.rs`, add native and + browser wrapper parity for one-shot cleanup failure -> retry success -> zero + sessions/pending interactions/process routes/cleanup tombstones. +9. Add a native stdio unit test around `cleanup_connections` with a failing + sidecar cleanup seam or extracted reporter. Assert a host-visible tracing/log + record contains connection id plus every cleanup child. Do not test only that + the function returns; stdio intentionally has no receiver for that result. + +Avoid a test-only production default or environment variable.

The complete production change is confined to + `crates/client/src/cron.rs` plus the public re-export in + `crates/client/src/lib.rs`; the remaining edits are tests and call-site updates. + +## Original issue and exact current path + +The callback closure is one of the few resources that legitimately remains in a +thin client: an in-process Rust closure cannot cross the protocol. The defect is +not that Rust runs the callback; it is that Rust discards its outcome. + +1. `crates/client/src/cron.rs:34-50`, `CronAction::Callback`, requires + `BoxFuture<'static, ()>`. +2. That unit-returning type is copied into `CallbackRoute.callback` at lines + 201-205 and `CronManager::allocate_callback` at lines 309-327. +3. `CronManager::callback_for_run` at lines 354-365 returns the same unit future + and increments the route's in-flight count. +4. `CronManager::execute_run` at lines 557-600 already sends + `action_result.err()` as `CompleteCronRunRequest.error`. +5. `run_host_action` at lines 614-631 awaits the callback at line 627, discards + the output, and manufactures `Ok(())` at line 628. A caller therefore cannot + provide the error that `execute_run` already knows how to forward. +6. The placeholder returned when a sidecar-owned job names a callback route that + is unavailable on this host, `CronManager::callback_action` at lines 375-395, + only logs at lines 387-390 and also returns unit.

The Rust client should supply the already-supported optional +error string; the sidecar continues to own classification, limits, run state, +and lifecycle events. + +## Exact replacement + +### 1. Define one public Rust callback boundary + +In `crates/client/src/cron.rs`, immediately before `CronAction`, add: + +```rust +/// Result returned by a host cron callback and forwarded to the sidecar. +pub type CronCallbackResult = Result<(), String>; + +/// Host callback retained by the client because closures cannot cross the wire. +pub type CronCallback = Arc< + dyn Fn() -> futures::future::BoxFuture<'static, CronCallbackResult> + + Send + + Sync, +>; +``` + +Then replace the four repeated callback signatures with `CronCallback`: + +- `CronAction::Callback { callback: CronCallback }` +- `CallbackRoute { callback: CronCallback, ... }` +- `CronManager::allocate_callback(&self, callback: CronCallback)` +- `CronManager::callback_for_run(...) -> Result` + +`Result<(), String>` is deliberately wire-shaped. It lets the host choose the +message, matches the existing `CronAlarmHandler` error boundary at +`crates/client/src/cron.rs:126-130`, and avoids introducing `anyhow`, a boxed +error policy, or a `ClientError::Sidecar` display prefix into user callback text. + +Re-export both aliases from `crates/client/src/lib.rs:85-88` with the existing +cron types: + +```rust +pub use cron::{ + CronAction, CronAlarmHandler, CronAlarmUpdate, CronCallback, + CronCallbackResult, CronEvent, CronJobHandle, CronJobInfo, CronJobOptions, + CronManager, CronOverlap, +}; +``` + +### 2. Preserve the exact error string through the existing request + +Change `callback_for_run` to return `Result` and preserve +its current route lookup plus `active_runs += 1` behavior: + +```rust +fn callback_for_run(&self, callback_id: &str) -> Result { + let mut registry = self.callbacks.lock(); + let route = registry + .routes + .get_mut(callback_id) + .ok_or_else(|| format!("cron callback route not found: {callback_id}"))?; + route.active_runs += 1; + Ok(route.callback.clone()) +} +``` + +Change `run_host_action` to return `CronCallbackResult` and return the callback +future's result directly: + +```rust +async fn run_host_action( + manager: &Arc, + action: WireCronAction, +) -> CronCallbackResult { + match action { + WireCronAction::Session { .. } => Err(String::from( + "sidecar returned non-host cron action to client: session", + )), + WireCronAction::Exec { .. } => Err(String::from( + "sidecar returned non-host cron action to client: exec", + )), + WireCronAction::Callback { callback_id } => { + let callback = manager.callback_for_run(&callback_id)?; + callback().await + } + } +} +``` + +At `execute_run` lines 562-570, map JSON decode failure directly to `String` +instead of `ClientError`, then leave line 589 semantically as a direct +`action_result.err()` assignment: + +```rust +let action = serde_json::from_str::(&run.action) + .map_err(|error| format!("invalid cron action: {error}")); +// ... +error: action_result.err(), +``` + +Do not use `.map(ClientError::Sidecar)` or `.map(|error| error.to_string())` for +the callback result. `ClientError::Sidecar` displays as `sidecar error: ...`, +which would decorate Rust's callback message while TypeScript forwards the +message exactly. + +Retain the existing `complete_callback_run` call before the transport request. +It is host-route lifecycle cleanup, not run classification, and must happen for +both `Ok` and `Err` callback results. + +### 3. Make a missing local callback route fail when invoked + +In `CronManager::callback_action` at lines 375-395, replace the logging-only +placeholder future with a typed failure: + +```rust +Arc::new(|| { + Box::pin(async { + Err(String::from( + "cron callback route is unavailable on this host", + )) + }) +}) +``` + +The placeholder is used only to represent sidecar job information through the +public `CronAction` type. Listing a job must remain side-effect-free. If a caller +explicitly invokes that returned closure, the result should describe failure; +it should not log and pretend success. No callback ID needs to be exposed in the +public message. + +### 4. Update all current Rust callback call sites + +A repository-wide search currently finds exactly three constructing call sites: + +- `crates/client/tests/cron_e2e.rs:35-41`: notify, then return `Ok(())`. +- `crates/client/tests/cron_e2e.rs:85-87`: use + `Box::pin(async { Ok(()) })`. +- `crates/client/tests/cron_grammar_e2e.rs:14-18`: use + `Box::pin(async { Ok(()) })`. + +The actor plugin schedules serializable exec/session actions and does not +construct `CronAction::Callback`; no actor production call site changes. + +Do not catch panics in Item 37. `Err(String)` is the supported failure result. A +panic is a host task failure and needs a separate, explicit unwind/lifecycle +design if it is to become recoverable. + +## Validation checklist + +### Before behavior + +Use the Item 36 parent for both pieces of evidence: + +1. Add the after-regression callback returning + `Err("rust callback failed".to_string())`. `cargo test -p agentos-client + --test cron_e2e --no-run` fails with the callback future output mismatch + (`expected (), found Result`). This proves the public API cannot express a + callback failure. +2. For a runnable baseline demonstration, temporarily make the old unit-returning + callback await a `Result::Err`, assert/record that host failure locally, then + return `()`. The existing real-sidecar event loop observes + `CronEvent::Complete` and no `CronEvent::Error`. This proves the forced discard + is acknowledged as success. Remove this temporary old-shape case after + recording the tracker evidence. + +### After: fast Rust forwarding regression + +Add a private unit test next to the existing tests in +`crates/client/src/cron.rs:959-1045`: + +- create `Arc`; +- allocate a callback returning `Err("rust callback failed".to_string())`; +- run the corresponding `WireCronAction::Callback` through `run_host_action`; +- assert the result is exactly `Err("rust callback failed")`; +- call `complete_callback_run` and assert the unscheduled route is released. + +This directly guards the code that formerly manufactured `Ok(())` without a +real-time cron delay. + +### After: real Rust sidecar classification + +Add `failed_cron_callback_is_recorded_as_error` to +`crates/client/tests/cron_e2e.rs`: + +1. Subscribe with `os.cron_events()` before scheduling. +2. Schedule a uniquely named one-shot callback about one second in the future; + its future returns `Err("rust callback failed".to_string())`. +3. Within one bounded eight-second wait, consume events until the exact job has + emitted `CronEvent::Fire` and then `CronEvent::Error` with the exact message. +4.

An explicit partial top-level policy also inherits `allow` for every omitted + scope. For example, `{ fs: "deny" }` still has `network`, `childProcess`, + `process`, `env`, and `binding` set to `allow`. +3. Inside a scope that is explicitly represented as a rule set, an omitted + rule-set `default` is **deny** (`unwrap_or(PermissionMode::Deny)` at + `crates/native-sidecar-core/src/permissions.rs:125` and line 145). Last + matching rule wins. +4. The generic kernel remains fail-closed when handed an unnormalized policy + with missing domains. AgentOS callers do not receive that generic default: + native create normalizes in + `crates/native-sidecar/src/vm.rs::NativeSidecar::create_vm` immediately after + decoding `CreateVmConfig` (currently line 197), native configure normalizes + explicit replacements in `NativeSidecar::configure_vm` (currently lines + 450-456), and browser create normalizes in + `crates/native-sidecar-browser/src/wire_dispatch.rs::BrowserWireDispatcher::create_vm` + (currently line 1572). Browser configure uses the same helper for explicit + replacement policies at lines 724-735 and preserves omission as "leave the + installed policy unchanged." +5. Allowing a permission scope does not manufacture a host capability. The guest + still sees only its virtual process/filesystem/network paths and only mounts + or bindings that the trusted host explicitly configured. Network permission + is also separate from listener loopback confinement and destination/egress + controls. + +Authoritative existing behavior tests include: + +- `crates/native-sidecar/src/vm.rs` — omitted domains in a partial policy inherit + the sidecar allow-all default. The exact anchor is + `vm::tests::omitted_permission_domains_use_the_sidecar_allow_all_default` + (currently line 2330). +- `crates/native-sidecar/tests/service.rs:8102` — a VM with no policy can read and + write as a guest in + `create_vm_without_permissions_defaults_to_static_allow_all`. +- `crates/native-sidecar-browser/tests/wire_dispatch.rs::browser_wire_create_vm_without_permissions_defaults_to_allow_all` + (currently line 2279) — browser wire create with no policy defaults to + allow-all. +- `packages/runtime-browser/tests/runtime/converged-permissions.test.ts:5` — the + converged browser harness uses allow-all. + +Do not change or delete generic-kernel deny tests such as +`crates/kernel/tests/default_deny_guards.rs` or +`crates/native-sidecar-core/src/permissions.rs:407`.

Add a warning +that allow-all authorizes only capabilities present inside/configured for the VM; +it does not expose the real host filesystem or host process table. + +The `grant-network` snippet at +`website/src/content/docs/docs/permissions.mdx:34` is now a no-op because network +is already allowed on omission. Remove it rather than teaching a redundant +override. Correspondingly simplify: + +- `examples/permissions/server.ts:4-7,37-44`: remove `grantNetwork` and its + spread; retain the explicit host allowlist, filesystem deny rule, and binding + allowlist. +- `examples/permissions/README.md:12-18`: describe three composed restrictive + policies rather than “network granted outright” plus a later override. + +The `bind-policy.ts` example may keep an explicit `network: "allow"`; explicit +allow is valid even though it matches the product default. + +### Security model + +- `website/src/content/docs/docs/security-model.mdx:13-22,140-145` and + `website/public/docs/docs/security-model.md:9-18,127-132` say everything or + network is denied until opt-in and describe a secure mixed baseline. + +Rename/reframe “Deny by default” as “Sidecar-enforced permissions” or +“Allow-all product default, explicit restrictions.” State that the sidecar +resolves omission to allow-all before installing policy in the kernel, and that +callers running untrusted workloads should pass explicit denies/allowlists. Keep +the accurate isolation facts: no implicit host mounts, guest processes are +virtual, all operations cross the enforcement point, and applied policies cannot +be bypassed. + +The page should explicitly distinguish permission posture from capability +existence. An allowed `fs` scope still addresses the VM VFS, and an allowed +`process` scope still addresses kernel-managed guest processes. + +### Networking page + +- `website/src/content/docs/docs/networking.mdx:52` and + `website/public/docs/docs/networking.md:29` say the guest cannot reach the + network by default. + +Replace that paragraph with an explicit statement such as: + +```text +When `permissions` or its `network` scope is omitted, network operations are +allowed. Pass an explicit `network: "deny"` or rule set to restrict destinations. +Permission is separate from loopback-only listener exposure and the egress/DNS +controls described below. +``` + +Keep the existing explicit `default: "deny"` allowlist example; it is correct. + +### Python runtime page + +- `website/src/content/docs/docs/python-runtime.mdx:43` and + `website/public/docs/docs/python-runtime.md:41` call package downloads + “default-deny + allowlist.” + +State instead that `pip` follows the VM network policy, network is allowed when +the policy/scope is omitted, and callers can pass an explicit deny or allowlist. + +### Architecture filesystem and process pages + +- `website/src/content/docs/docs/architecture/filesystem.mdx:57` and public + counterpart line 55 say nothing is bound and filesystem access is denied by + default. +- `website/src/content/docs/docs/architecture/processes.mdx:36` and public + counterpart line 34 say process execution is denied by default. + +Retain the kernel permission-check step but make the product resolution clear: +the AgentOS sidecar installs `allow` for an omitted scope, while an explicit +policy can deny and returns `EACCES`. Do not weaken the statement that the kernel +always checks the applied policy. + +### Main architecture page + +- `website/src/content/docs/docs/architecture.mdx`, under + `### Permissions & approvals` (currently line 303), and + `website/public/docs/docs/architecture.md`, under the same heading (currently + line 170), say that the kernel policy means "nothing is allowed until you opt + in." + +Replace that parenthetical with the actual two-layer contract. Recommended +copy: + +```text +The lower-level permission policy is enforced by the kernel on every guest +syscall. The sidecar resolves omitted top-level scopes to `allow`; pass explicit +denies or rule sets when the workload needs restriction. Approvals are a +separate layer for an agent asking before it uses a tool. +``` + +This page was absent from the first Item 38 inventory. It is an Item 38 change, +not Item 51's general architecture cleanup, because it makes the exact same +incorrect permission-default claim as the dedicated permissions page. + +### Comparison page + +- `website/src/content/docs/docs/versus-sandbox.mdx:19` and + `website/public/docs/docs/versus-sandbox.md:17` advertise “Granular, + deny-by-default.” + +Use “Granular and sidecar-enforced; allow-all when omitted” or equivalent. + +### Already correct; preserve + +- `website/src/content/docs/docs/filesystem.mdx:89` and its public counterpart + correctly say filesystem is granted by default. +- `website/src/content/docs/docs/architecture/networking.mdx:85-111` correctly + separates permission policy, loopback confinement, and destination/egress + controls. Its “loopback-only by default” wording is not a permission-default + claim and must not be banned. +- Explicit rule examples and prose saying `default: "deny"` creates an allowlist + are correct and must continue to pass the verifier. + +## Implementation-ready edit map + +Use these replacements in both the source MDX and checked public Markdown copy +where a pair exists.

Pi is an explicit caller +package choice. Making every VM contain Pi would violate the thin-client rule in +the other direction by turning an application package choice into a runtime +default. The fix is to make the example forward its explicit package input. + +`@mariozechner/pi-coding-agent` should also disappear from the install command. +It is already a direct dependency of `@agentos-software/pi` at +`registry/agent/pi/package.json:31-34`; users should not have to install the +adapter implementation twice or coordinate its version manually. + +## Recommended source of truth + +Reuse `examples/quickstart/agent-session/index.ts`; do not introduce another +near-identical Pi example. It is already a workspace package, has a real +`check-types` command, and currently projects Pi explicitly. Narrow it from the +current three-agent selector to the Pi-only flow advertised by the core README. + +Wrap the runnable portion in the repository's existing snippet markers: + +```ts +// docs:start core-readme-quickstart +import pi from "@agentos-software/pi"; +import { AgentOs } from "@rivet-dev/agentos-core"; + +const apiKey = process.env.ANTHROPIC_API_KEY; +if (!apiKey) { + throw new Error("ANTHROPIC_API_KEY is required"); +} + +const vm = await AgentOs.create({ software: [pi] }); + +try { + const { sessionId } = await vm.createSession("pi", { + env: { ANTHROPIC_API_KEY: apiKey }, + }); + + try { + const { text } = await vm.prompt( + sessionId, + "Write a hello world in TypeScript", + ); + console.log(text); + } finally { + await vm.closeSession(sessionId); + } +} finally { + await vm.dispose(); +} +// docs:end core-readme-quickstart +``` + +The explicit API-key check avoids forwarding an `undefined` value disguised by +a TypeScript non-null assertion. The nested cleanup is deliberate: a failed +prompt still closes its live ACP session, and a failed +create-session/prompt/close still releases the VM. The README code fence should +contain the exact region content without the two marker lines. This keeps the +copy-paste path simple while allowing an automated equality check. + +Do not add `common` to this snippet. `AgentOs.create()` currently supplies the +TypeScript package manager's allowed default package bundle, while Pi is the +explicit non-default package that this regression is about. Passing only +`software: [pi]` demonstrates the required contract without duplicating the +package manager's default list at the call site. + +## Exact edits + +### `packages/core/README.md` + +Replace lines 21-42 as one unit: + +1. Install `@rivet-dev/agentos-core` and `@agentos-software/pi`; remove the + separate `@mariozechner/pi-coding-agent` install and its misleading comment. +2. Import the default `pi` package reference. +3. call `AgentOs.create({ software: [pi] })`. +4. Fail clearly when `ANTHROPIC_API_KEY` is absent; otherwise pass the concrete + string in session `env`, destructure the documented `{ text }` prompt result, + print it, and use awaited `try/finally` cleanup. +5. Keep the TypeScript fence byte-for-byte equal to the marked checked-example + region after normalizing final newlines. + +Do not edit the hand-maintained API inventory below the quickstart; Item 55 owns +that separate defect. + +### `examples/quickstart/agent-session/index.ts` + +Replace the current multi-agent setup at lines 1-43 with the marked Pi-only code +above. Delete the `SoftwareInput`, Claude, and OpenCode imports, the three-package +`software` array, the agent selector, event-log boilerplate, and the conditional +empty env assembly. Those abstractions make the example broader without helping +the one package it actually selects. + +### `examples/quickstart/agent-session/README.md` + +Update lines 2-21 to say the example runs Pi, projects the Pi package explicitly, +requires `ANTHROPIC_API_KEY`, and prints the prompt result.

Run a +lockfile-only install/update so the workspace importer in `pnpm-lock.yaml` +matches. Do not remove shared packages globally merely because this one example +no longer imports them. + +### `packages/core/tests/readme-quickstart.test.ts` + +Add the acceptance file named by the tracker. It should have three fast tests +(or two tests with the two execution cases parameterized): + +1. Extract the first `typescript` fence under `## Quick Start` in + `packages/core/README.md`, extract `docs:start/end core-readme-quickstart` + from `examples/quickstart/agent-session/index.ts`, and require equality after + trimming only the final newline. Missing/duplicate fences or markers must be + explicit failures, not an empty match. +2. Execute the extracted README program on its success path against deterministic + injected test doubles for `AgentOs`, `pi`, `process`, and `console`. Remove + the two known one-line imports, transpile the remaining TypeScript with the + already-present `typescript` development dependency + (`packages/core/package.json:103`), and run it in an `AsyncFunction`. Reject + any other import instead of silently stripping arbitrary code. The + fake VM must model the relevant runtime invariant: `createSession("pi")` + throws `unknown agent type: pi` unless the exact injected Pi descriptor was + present in `AgentOs.create({ software })`. After execution, assert this order + and data: + + - `create` received `software: [pi]`; + - `createSession` received `"pi"` and the injected API key; + - `prompt` received the returned session ID and expected prompt; + - `closeSession` was awaited before `dispose`; + - the returned `text` was logged. +3. Execute the same extracted program with `prompt` rejecting. Assert that the + original prompt error propagates, `closeSession` completes, and only then + `dispose` completes. This validates the cleanup behavior shown to users rather + than merely asserting that the method names occur in the snippet. + +Keep this default test transport-free. It executes the actual published snippet +and proves the regression's data flow without booting the built Pi package or +calling an external model API on every PR. Do not mock or change production +`AgentOs` modules globally; inject the two imports only into the extracted +snippet's evaluation scope. + +The real integration proof already exists in +`packages/core/tests/pi-headless.test.ts`: `createPiVm` at lines 49-55 passes +`[common, pi]`, the first case at lines 85-119 initializes the real Pi SDK ACP +adapter, and the following cases exercise prompts through LLMock and clean up. +Run that focused file in the expensive validation phase instead of copying its +model/bootstrap scaffolding into the documentation test. + +## Before and after validation + +### Before evidence + +Add the final extraction/execution harness first on the Item 38 parent, before +editing either snippet. Its success-path test must fail because the current +README calls `AgentOs.create()` without Pi; the fake reaches +`createSession("pi")` and throws `unknown agent type: pi`. Record this exact test +name, command, and observed failure in the Item 39 tracker checklist. Do not +weaken or invert the final assertion just to capture the before evidence. + +```sh +pnpm --dir packages/core exec vitest run tests/readme-quickstart.test.ts +``` + +Also record the existing multi-agent example's typecheck before replacement; +that is a compatibility baseline, not proof that the README works: + +```sh +pnpm --dir examples/quickstart/agent-session check-types +``` + +Current-checkout audit on 2026-07-14: this command exits 2 before checking the +example because `examples/quickstart/agent-session/node_modules` is absent and +TypeScript cannot resolve `@agentos-software/opencode`. That is an installation +precondition, not Item 39's before failure. Run the baseline after the normal +workspace dependency install has created this nested workspace package's links; +do not record the missing-link error as behavioral evidence. + +### After evidence + +Run the same fast test after synchronizing the README and example. It must execute +through prompt and both cleanup calls, its failure case must still clean up, and +its source-equality assertion prevents the README from drifting back to an +unprojected package. + +```sh +pnpm --dir packages/core exec vitest run tests/readme-quickstart.test.ts +pnpm --dir examples/quickstart/agent-session check-types +pnpm --dir packages/core check-types +``` + +Then run the existing real adapter proof as expensive validation. It requires +built registry artifacts and the native sidecar, but no real API key because it +uses LLMock: + +```sh +AGENTOS_E2E_FULL=1 pnpm --dir packages/core exec vitest run tests/pi-headless.test.ts +``` + +Finally run `git diff --check` and update all three Item 39 checkboxes plus its +status row in `docs/thin-client-migration.md` only after the fast and real tests +pass. + +## Dependencies and risks + +- **Item 55 path overlap:** it also owns `packages/core/README.md`. Land Item 39 + first or rebase Item 55 and preserve the checked quickstart block. +- **Item 51 documentation verifier:** if its scan later includes package READMEs, + retain the explicit-package positive claim and point it at this source-equality + test rather than creating a second snippet verifier. +- **Built artifacts:** the real Pi test imports + `registry/agent/pi/dist/package.aospkg`; it must be built before the expensive + run. The fast documentation test must not depend on that artifact. +- **Workspace install:** the nested example currently has no local + `node_modules`, so its standalone `check-types` command cannot resolve its + workspace dependencies. Run the normal workspace install before claiming the + before/after typecheck result; this is independent of the quickstart defect. +- **No network in default CI:** executing the checked file directly would call a + model and require loopback exception/model setup for LLMock. The injected + execution harness is intentional; actual sidecar behavior stays covered by + `pi-headless.test.ts`. +- **Cleanup assertions:** recording only invocation order is not enough if + promises are not awaited. Make fake close/dispose promises complete on + separate microtasks and assert their completion flags, so removing `await` + fails. +- **Manifest cleanup scope:** the same copied dependency inventory appears in + sibling `examples/quickstart/*/package.json` files.

It emitted noisy +near-capacity warnings for the +`sidecar_stdout_frames` queue, but did not lose functionality. Treat that as a +separate observability concern, not a reason to weaken this test. + +## What the current test really exercises + +This is more than an in-memory persistence unit test: + +1. `ensure_vm` in `crates/agentos-actor-plugin/src/vm.rs:63-133` starts an + `AgentOs` VM through the configured `agentos-sidecar` wrapper and installs the + actor SQLite-backed JS bridge. +2. The test schedules `survives-sleep` one hour in the future in the sidecar-owned + cron registry, exports the opaque registry, and stores it in the mock actor's + real in-memory SQLite database. +3. `shutdown_vm` takes the first `AgentOs` handle and calls + `AgentOs::shutdown`. Because this test uses a UUID-unique shared pool with one + VM, the client closes the VM's wire session, releases the last lease, kills + the sidecar connection, disposes the pooled sidecar handle, and removes it + from the pool (`crates/client/src/agent_os.rs:457-539` and + `crates/client/src/sidecar.rs:199-206,239-278`). +4. The second `ensure_vm` therefore creates a new pooled sidecar handle/process, + creates a new VM, loads the opaque SQLite value, and imports it into the new + sidecar scheduler. Finding `survives-sleep` proves restoration across a real + cold boot; the scheduled command never executes and needs no network. + +There is one important test hole: `shutdown_vm` logs and swallows a failed +`AgentOs::shutdown` at `crates/agentos-actor-plugin/src/vm.rs:161-175`. If that +shutdown failed, the test could create another VM against the still-live pooled +sidecar and find the original in-memory cron job instead of proving restoration. +The implementation should close that hole in test assertions without changing +the actor's best-effort production shutdown contract. + +The module header at `persistence_e2e.rs:1-8` also says “No VM, no sidecar.” That +is true for the storage-bridge tests but false for this cold-boot test and should +be narrowed as part of the test edit. + +## Exact test edits + +Edit `crates/agentos-actor-plugin/src/persistence_e2e.rs` only; no actor runtime +production edit is necessary. + +### 1. Make the prerequisite fail closed + +Replace the two skip-and-return branches at lines 531-539 with mandatory setup: + +```rust +let sidecar_path = std::env::var("AGENTOS_SIDECAR_BIN") + .expect("actor cold-boot cron E2E requires AGENTOS_SIDECAR_BIN"); +let sidecar_file = std::path::Path::new(&sidecar_path); +assert!( + sidecar_file.is_file(), + "AGENTOS_SIDECAR_BIN does not point to a file: {}", + sidecar_file.display() +); +``` + +Do not add a Unix executable-bit assertion to the Rust test. `is_file` gives a +clear configuration diagnostic on every supported host, the CI shell can check +`-x` on Linux, and `ensure_vm` already propagates an actual spawn failure. + +### 2. Prove teardown and a distinct cold boot + +Immediately before the first `shutdown_vm`, retain the public sidecar handle. +`AgentOs::sidecar` is public at `crates/client/src/agent_os.rs:575-579`, and +`describe` exposes lifecycle state and lease count at +`crates/client/src/sidecar.rs:215-228`: + +```rust +let first_sidecar = first.sidecar(); +crate::vm::shutdown_vm(&host, &mut vm, "sleep").await; +assert!(vm.is_none(), "sleep must drop the first VM handle"); +let first_description = first_sidecar.describe(); +assert_eq!(first_description.active_vm_count, 0); +assert_eq!( + first_description.state, + agentos_client::SidecarState::Disposed, + "sleep must dispose the one-VM sidecar before cold boot" +); +``` + +After the second `ensure_vm`, retain its sidecar and prove that the pool did not +reuse the disposed handle: + +```rust +let restored = vm.as_ref().expect("restored VM"); +let restored_sidecar = restored.sidecar(); +assert!( + !std::sync::Arc::ptr_eq(&first_sidecar, &restored_sidecar), + "cold boot must allocate a new sidecar handle" +); +assert_eq!(restored_sidecar.describe().active_vm_count, 1); +``` + +Keep the existing restored-job assertion: that is the actual import proof. After +the final `shutdown_vm`, assert that `vm.is_none()` and that +`restored_sidecar.describe()` is `SidecarState::Disposed` with zero active VMs +as a cleanup assertion. + +```rust +crate::vm::shutdown_vm(&host, &mut vm, "destroy").await; +assert!(vm.is_none(), "destroy must drop the restored VM handle"); +let restored_description = restored_sidecar.describe(); +assert_eq!(restored_description.active_vm_count, 0); +assert_eq!( + restored_description.state, + agentos_client::SidecarState::Disposed, + "destroy must dispose the restored one-VM sidecar" +); +``` + +This is stronger than checking only `vm.is_none()`: `shutdown_vm` calls +`vm.take()` before attempting the fallible shutdown, so `None` by itself cannot +prove the sidecar/session was closed. + +### 3. Correct the module description + +Revise `persistence_e2e.rs:1-8` to say that most tests isolate the real SQLite +storage bridge without a VM, while `actor_cold_boot_restores_sidecar_owned_cron_state` +intentionally launches a real sidecar and VM to prove opaque cron restoration. + +Do not change `crates/agentos-actor-plugin/src/vm.rs`, client lifecycle code, +protocol schemas, Cargo manifests, or lockfiles for Item 40. + +## Exact CI edits + +The required executable is the wrapper package/bin `agentos-sidecar`, declared +in `crates/agentos-sidecar/Cargo.toml`; it is **not** +`agentos-native-sidecar`. The wrapper is the same binary resolved by normal +Rust-client startup and includes the native runtime implementation. + +### `.github/workflows/ci.yml` + +The `rust` job currently downloads/copies the WASM command artifact and runs +clippy plus selected crate tests, but it never runs actor-plugin tests or sets +`AGENTOS_SIDECAR_BIN`. Add these steps after the current clippy step and before +the existing `Reclaim Cargo target space before package tests` step: + +```yaml + - name: Build sidecar for actor persistence E2E + run: cargo build -p agentos-sidecar + env: + CARGO_TARGET_DIR: ${{ github.workspace }}/target + - name: Test actor cron cold boot + run: | + test -x "$AGENTOS_SIDECAR_BIN" + cargo test -p agentos-actor-plugin persistence_e2e -- --test-threads=1 --nocapture + env: + CARGO_TARGET_DIR: ${{ github.workspace }}/target + AGENTOS_SIDECAR_BIN: ${{ github.workspace }}/target/debug/agentos-sidecar +``` + +Use the module filter `persistence_e2e`, matching the tracker checklist, rather +than running only the named test. It keeps the cheap SQLite behavior tests next +to the real cold-boot assertion. Explicit `cargo build` is required: `cargo +test` may compile a hashed test executable but does not promise the stable +`target/debug/agentos-sidecar` binary path. + +The actor package is already a root workspace member (`Cargo.toml:3-24`), but +the regular `rust` job currently runs only protocol, sidecar, and client tests +at `.github/workflows/ci.yml:115-120`. + +The build/test must remain after the WASM commands are copied and before `cargo +clean`. Do not inherit `AGENT_OS_CLIENT_ALLOW_E2E_SKIPS=1` from the client-test +step; this actor step must have no skip permission. + +### `.github/workflows/ci-nightly.yml` + +Nightly currently executes `cargo test --workspace` at +`.github/workflows/ci-nightly.yml:34` before its release native-sidecar build. +Add a debug wrapper build immediately before the workspace tests and pass the +stable path to that test step: + +```yaml + - run: cargo build -p agentos-sidecar + env: + CARGO_TARGET_DIR: ${{ github.workspace }}/target + - run: cargo test --workspace -- --test-threads=1 + env: + CARGO_TARGET_DIR: ${{ github.workspace }}/target + AGENTOS_SIDECAR_BIN: ${{ github.workspace }}/target/debug/agentos-sidecar +``` + +Keep the later release build of `agentos-native-sidecar`; it serves the benchmark +matrix and cannot satisfy this earlier actor test or its wrapper-binary contract. + +### `scripts/ci.sh` + +The repository's local CI entry point likewise omits the actor plugin: its Rust +list ends with `agentos-client` at `scripts/ci.sh:40-45`.

Actor callers use the corresponding `allProcesses` action. A caller +that needs presentation-specific indentation can format that flat snapshot at +its UI boundary, just as Linux tools format `/proc`/`ps` data. AgentOS should not +own a second recursive process model. + +The tracker currently says medium confidence because move-versus-remove had not +been resolved. Current repository usage, the already-complete flat response, and +the cost of adding an otherwise-unused recursive protocol resolve that ambiguity +in favor of removal. + +## Current duplicated behavior + +### TypeScript + +`packages/core/src/agent-os.ts:2065-2087` calls `allProcesses()`, creates one +mutable node per PID, then attaches each node to the node whose PID matches its +`ppid`. A node becomes a root only when its parent PID is absent. + +`allProcesses()` is already sidecar-authoritative on the production path: +`packages/core/src/agent-os.ts:2057-2063` calls the native proxy's +`snapshotProcesses()` method; `packages/core/src/sidecar/rpc-client.ts:747-775` +requests the process snapshot; and `buildProcessSnapshot` at lines 1006-1034 +maps and PID-sorts the response. The tree method adds no runtime data. + +### Rust + +`crates/client/src/process.rs:641-644` calls `all_processes()` and then the private +`build_process_forest` at lines 1080-1125. That helper independently implements +the same roots/children policy and carries a Rust-only `seen` guard. The public +recursive type is declared at lines 170-175 and re-exported from +`crates/client/src/lib.rs:60-63`. + +Both clients therefore own these semantics: + +- an entry whose `ppid` is absent is a root; +- parent and child order follows the PID-sorted flat snapshot; +- a self-parented entry finds itself as its parent and disappears from the root + forest; +- a closed parent cycle likewise has no root and disappears; +- the snapshot's parent linkage, not a sidecar tree result, determines shape. + +The algorithms agree for valid kernel snapshots but are still two state-shaping +implementations. They are also unnecessary because the flat snapshot is public. + +## Existing sidecar and protocol capability + +Keep the existing wire surface unchanged: + +- `GetProcessSnapshotRequest` is declared at + `crates/sidecar-protocol/protocol/agentos_sidecar_v1.bare:409`. +- `ProcessSnapshotEntry` at lines 704-718 carries the authoritative process ID, + kernel `pid`/`ppid`/`pgid`/`sid`, command, argv, cwd, status, exit code, and + timestamps. +- `ProcessSnapshotResponse` at lines 720-722 returns a flat bounded list. +- Native dispatch in `crates/native-sidecar/src/execution.rs:4321-4349` checks + exact VM ownership and `process.inspect`, prunes bounded exited snapshots, and + returns the VM snapshot. +- Browser dispatch in + `crates/native-sidecar-browser/src/wire_dispatch.rs:1088-1119` returns the + browser sidecar's process snapshot through the same response. +- Shared field conversion already lives in + `crates/native-sidecar-core/src/diagnostics.rs`; both implementations use + `SharedProcessSnapshotEntry`. + +The default kernel process limit is finite (`DEFAULT_MAX_PROCESSES == 256`), and +exited route retention is derived from the resolved process limit. Removing the +tree view neither weakens bounds nor changes inspection permission enforcement. + +Do **not** add `GetProcessTreeRequest`, a recursive BARE type, JSON tree payload, +root/child PID graph, or sidecar tree helper for Item 41. Those are all more code +than deleting the unused view. Do not modify snapshot enumeration, PID sorting, +permission checks, or native/browser process coverage in this revision. + +## Exact production edits + +### TypeScript core + +In `packages/core/src/agent-os.ts`: + +1.

Generic internal phrases +such as native process termination helpers named “process tree” are unrelated +and should not be renamed. + +Update Item 41's acceptance row in `docs/thin-client-migration.md` to reflect the +chosen removal path: the before checkbox cites the two characterization tests; +replace the current “Sidecar tree tests” wording with removal guards plus +authoritative flat-snapshot tests; the work-item confidence becomes high; and +the completion checkbox is marked only after the dedicated revision and all +focused gates pass. + +## Public API and migration implications + +- **TypeScript core:** removes `AgentOs.processTree()` and the exported + `ProcessTreeNode` type. +- **Rust client:** removes `AgentOs::process_tree()` and the exported + `ProcessTreeNode` struct. +- **Actor API:** removes the `processTree` action and generated client method. +- **Wire protocol:** unchanged; `GetProcessSnapshotRequest` remains available to + both clients through `allProcesses` / `all_processes`. +- **Permissions:** unchanged; `allProcesses` continues to require the sidecar's + `process.inspect` permission decision. +- **Migration:** callers consume the flat list and read each entry's `ppid`. + Do not publish a replacement tree helper from another AgentOS package. + +An older generated actor client calling `processTree` against a new actor plugin +will receive the ordinary unknown-action error. That is acceptable only because +the actor/plugin/client artifacts are released together; call out the removal in +release notes even though no compatibility shim should be added. + +## Risks and dependencies + +- **Stack predecessor:** implement only after Item 40 is sealed, as required by + the one-item-per-revision stack. Item 40 owns actor persistence CI; do not mix + its workflow changes into Item 41. +- **Item 55 path overlap:** it also changes the hand-maintained API inventory in + `packages/core/README.md`. Land/rebase carefully so `processTree` is not + regenerated into the inventory. +- **Items 70 and 71 assume this API remains:** their current research mentions + `processTree` in later process snapshot/cache work. Update those planning notes + in this revision so their implementations do not restore or special-case the + deleted surface. +- **Generated actor file:** changing only the generated TypeScript file will be + overwritten by `build.rs`; `contract_surface.rs` is authoritative. +- **Contract match tables:** `processTree` appears in decoding, valid fixtures, + invalid fixtures, sample replies, and dispatch. Missing one will fail the + action contract suite, which is desirable. +- **Tests are not production users:** do not interpret the two current process + tree integration tests as evidence that the API is required. Their meaningful + parent/child assertion already exists on `allProcesses`. +- **Unrelated process-tree terminology:** native sidecar functions such as + `terminate_child_process_tree` implement required kill semantics and must + remain. Item 41 concerns only the public derived snapshot view. +- **No protocol regeneration:** removal does not edit the BARE schema. If an + implementation starts changing generated protocol files, it has drifted onto + the rejected move path. + +## Rejected move alternative + +If a future concrete consumer requires a sidecar tree, implement it as a new +sidecar-owned graph, not by restoring the client algorithms. A viable typed BARE +shape would return ordered root PIDs plus ordered child PID lists referencing the +existing process entries; a shared helper in `native-sidecar-core::diagnostics` +would classify roots/cycles once, and native/browser dispatchers would call it. +Clients would only hydrate that trusted graph into their language shape. + +That fallback would require protocol schema/generated-code updates, native and +browser dispatcher cases, shared root/orphan/cycle/order tests, TypeScript/Rust +deserializers, actor parity, and explicit response-size bounds.

Send the compiler request through the existing bounded process +stdin protocol and run the fixed compiler runner with `node -e`. Inside that +guest process, use `process.cwd()` as the only base for project, config, and +synthetic-source paths. + +Also correct explicit relative execution cwd once in shared sidecar behavior. +Native currently turns `cwd: "project"` into `/project`; browser forwards the +unresolved string `project`. Both must resolve it against the VM cwd, exactly as +Linux resolves a relative `chdir` target. TypeScript and Rust clients should +continue to forward an explicit cwd unchanged and preserve omission. + +The resulting flow is: + +```text +TypeScript request + -> Execute { argv: ["node", "-e", fixedRunner], stdin: request JSON, + cwd: explicit caller value or omitted } + -> shared sidecar cwd resolution + -> Node process.cwd() + -> TypeScript compiler +``` + +Rename the remaining secure-exec-era synthetic source name to +`__agentos_typescript_input__.ts`. + +This is smaller and more Linux-native than the old recommendation to retain two +files under `/tmp`: source requests no longer need guest filesystem writes, +there is nothing to bootstrap or clean up, and project emit retains only the +filesystem writes that compilation functionally requested. + +## Current issues and exact anchors + +### The compiler client bootstraps and transports through the filesystem + +`packages/typescript/src/index.ts:137-206` currently: + +1. calls `agentOs.mkdir("/tmp", { recursive: true })` and wraps failure in a + package-specific bootstrap error; +2. allocates an ID from client-global `nextRuntimeRequestId` at line 85; +3. writes a request JSON file and a generated CommonJS runner under `/tmp`; +4. executes the runner file; and +5. performs two existence probes and deletes the files in `finally` through + `removeGuestFileIfExists` at lines 300-307. + +None of that file lifecycle is compiler behavior. `execArgv` already accepts +`stdin`; the sidecar owns its bounded input route and closes it before wait. A +fixed `node -e` runner can collect request JSON from `process.stdin`. User source +remains on stdin, not argv, so request size does not inflate the process command +line. Use the stream interface rather than `fs.readFileSync(0)`: AgentOS's guest +`node:fs` shim special-cases numeric stdio for `readSync`, not `readFileSync`. + +The current `execArgv` options at lines 165-169 correctly preserve cwd omission: + +```ts +{ + ...(request.options.cwd === undefined + ? {} + : { cwd: request.options.cwd }), +} +``` + +Keep that presence behavior and add `stdin`; do not fill `/workspace`, `/root`, +or any other cwd default in the package. + +### The compiler applies cwd twice + +The embedded `compilerRuntimeMain` independently runs this in both +`resolveProjectConfig` and `createSourceProgram` at current lines 387 and 422: + +```ts +const cwd = path.resolve(options.cwd ?? "/root"); +``` + +The caller's `cwd` has already been supplied to process creation. Resolving the +same relative string again inside that process duplicates policy and can append +the directory twice. Both helpers should instead use: + +```ts +const cwd = process.cwd(); +``` + +`options.cwd` remains public because it selects the execution cwd; it should not +also be a compiler path base after the process starts. + +### Relative execution cwd is divergent in the sidecars + +The existing note incorrectly assumed the sidecar already resolved a relative +execution cwd against the VM cwd. Current code proves otherwise: + +- Native `resolve_guest_execution_cwd` at + `crates/native-sidecar/src/execution.rs:9889-9893` passes every present string + directly to `normalize_path`; `normalize_path("project")` produces `/project`. +- Browser execute dispatch at + `crates/native-sidecar-browser/src/wire_dispatch.rs:2019-2034` uses a present + payload cwd verbatim, so the same request remains `project`. +- Shared filesystem path resolution already has the correct rule in + `crates/native-sidecar-core/src/guest_fs.rs:23-34`: absolute paths normalize + from root; relative paths join the VM cwd; empty paths return `ENOENT`. + +Reuse that shared rule rather than adding a TypeScript-specific workaround or +copying another native/browser path function. + +### Legacy synthetic filename and example bootstrap + +`createSourceProgram` at `packages/typescript/src/index.ts:423-426` defaults an +in-memory source to `__secure_exec_typescript_input__.ts`. The migration map at +`scripts/secure-exec-agentos-map.json:305` already names the intended +`__agentos_typescript_input__` replacement; this literal was missed. + +The runnable example also calls `vm.mkdir("/root", { recursive: true })` at +`packages/secure-exec-example-ai-agent-type-check/src/index.ts:64` immediately +before writing its output. `/root` is already part of the Linux base.

It creates caller-requested output directories and is functional + compiler behavior. + +### Shared and native sidecar cwd resolution + +In `crates/native-sidecar-core/src/guest_fs.rs`, make the existing +`resolve_guest_path` function public. Keep its absolute/relative/empty semantics; +generalize the empty-path text from `guest filesystem path is empty` to `guest +path is empty`, and update the local assertion at current line 609. Do not create +another resolver. Re-export it from +`crates/native-sidecar-core/src/lib.rs:63-67`. + +In `crates/native-sidecar/src/execution.rs`: + +1. import `resolve_guest_path` from `agentos_native_sidecar_core`; +2. make `resolve_guest_execution_cwd` return + `Result`; +3. for an explicit cwd, call `resolve_guest_path(&vm.guest_cwd, value)` and map + its POSIX error through the existing `guest_kernel_core_error`; for omission, + clone `vm.guest_cwd`; +4. in `resolve_execution_cwds`, attempt the existing in-sandbox host-path + compatibility branch **only when `Path::new(raw_cwd).is_absolute()`**; + relative values such as `project`, `./project`, and `../project` must always + take the guest resolver, regardless of the sidecar process's host cwd; +5. make `resolve_execution_cwds` return a `Result`, wrapping the guarded + in-sandbox host-path compatibility return in `Ok(...)` and using `?` for the + shared guest-path fallback; and +6. add `?` at its two callers at current lines 9377-9378 and 9430. + +Do not otherwise disturb the host-path compatibility branch, host shadow +mapping, entrypoint resolution, `PWD`, or omitted-cwd behavior. The absolute +guard is important even though today's lexical `normalize_host_path("project")` +normally does not fall under an absolute `vm.host_cwd`: guest semantics must not +depend on the sidecar's launch directory or a future normalization change. This +edit only changes explicit relative guest paths and makes empty cwd fail instead +of becoming `/`. + +### Browser sidecar cwd resolution + +In `crates/native-sidecar-browser/src/wire_dispatch.rs`, import +`resolve_guest_path`. In `execute`, after the existing shell/PTY/timeout request +validation at current lines 1916-1950 but before process-ID allocation: + +1. read the VM's sidecar-owned base cwd once with `self.sidecar.guest_cwd`; +2. preserve it when `payload.cwd` is omitted; +3. resolve a present cwd with `resolve_guest_path(&vm_cwd, cwd)`; and +4. reject a lookup/resolution failure before allocating a process ID or browser + execution context. + +Delete the late verbatim/omission match at current lines 2019-2034 and pass the +already-resolved `guest_cwd` into `StartExecutionRequest`. This avoids creating a +context that must then be released merely to discover an invalid cwd. + +No sidecar protocol or generated binding changes are needed. `ExecuteRequest.cwd` +already carries an optional caller override. + +### Example and documentation + +In `packages/secure-exec-example-ai-agent-type-check/src/index.ts`, delete only +the `/root` mkdir at current line 64. Keep the explicit generated source/output +paths; an absolute `/root` path is valid Linux behavior and the base owns it. + +Delete the matching line from the checked runnable block at +`docs/features/typescript.mdx:78`. + +Add the user-facing contract to `packages/typescript/README.md` and, after the +setup section, `docs/features/typescript.mdx`: + +- requests run inside the caller-owned VM; +- omitted cwd uses that VM's resolved process cwd, normally `/workspace`; +- explicit absolute or relative cwd is resolved once by process creation, and + compiler-relative paths use that resulting `process.cwd()`; +- source requests are transported over process stdin and do not create temp + files; and +- project compilation may still read project files and write requested outputs. + +In +`packages/secure-exec-example-ai-agent-type-check/package.json`, change the +scoped script to: + +```json +"check-types": "tsc --noEmit -p tsconfig.json && pnpm verify-docs" +``` + +This makes the already-present checked-example contract part of root `pnpm +check-types` without adding a root orchestration script or workflow step. + +Do not rename the example directory in Item 42. Do not edit +`scripts/secure-exec-agentos-map.json`; it already records the intended literal +rename. + +## Before tests + +Add the desired regression tests first and run them against the completed Item +41 parent. Record the failing test names, output, parent jj revision, and command +in Item 42's tracker checklist before changing production code. + +Use these exact proposed test names and parent-failure commands after adding the +tests but before the production edit: + +```sh +pnpm --dir packages/typescript exec vitest run \ + tests/typescript-tools.integration.test.ts \ + -t "uses stdin without compiler transport files and inherits the VM cwd" + +pnpm --dir packages/typescript exec vitest run \ + tests/typescript-tools.integration.test.ts \ + -t "resolves a relative project cwd once against the VM cwd" + +cargo test -p agentos-native-sidecar-browser --test wire_dispatch \ + browser_wire_dispatcher_handles_lifecycle_and_execution_frames -- --exact +``` + +The first must fail on Item 41 with the `/tmp` preparation diagnostic, the +second must fail because native resolves/duplicates the relative cwd, and the +third must fail because browser records `project` verbatim. If a test does not +fail for that reason, correct the characterization before implementation rather +than accepting a false-green parent. + +### No compiler transport writes and omitted cwd + +In `packages/typescript/tests/typescript-tools.integration.test.ts`, create a +dedicated VM with the normal `nodeModulesMount` and a filesystem rule that denies +all compiler transport mutations under `/tmp`: + +```ts +const restrictedVm = await AgentOs.create({ + defaultSoftware: false, + mounts: [nodeModulesMount(join(workspaceRoot, "node_modules"))], + limits: { jsRuntime: { v8HeapLimitMb: 256, cpuTimeLimitMs: 5_000 } }, + permissions: { + fs: { + default: "allow", + rules: [ + { + mode: "deny", + operations: ["write", "create_dir", "rm"], + paths: ["/tmp", "/tmp/**"], + }, + ], + }, + }, +}); +``` + +Call `typecheckSource` without cwd or filePath: + +```ts +const tools = createTypeScriptTools({ agentOs: restrictedVm }); +const result = await tools.typecheckSource({ + sourceText: "const value: string = 1;\n", +}); +const diagnostic = result.diagnostics.find(({ code }) => code === 2322); +expect(result.success).toBe(false); +expect(diagnostic?.filePath).toBe( + "/workspace/__agentos_typescript_input__.ts", +); +expect( + (await restrictedVm.readdir("/tmp")).filter((name) => + name.startsWith("agentos-typescript-"), + ), +).toEqual([]); +``` + +Construct `tools` with `restrictedVm` directly and dispose that VM in `finally`; +do not replace the shared fixture and accidentally deny legitimate project emit. + +On the parent this fails before compilation with code 0 and +`failed to prepare TypeScript runner directory`. Afterward it proves stdin +transport, no `/tmp` mutation, the sidecar's omitted `/workspace` cwd, the new +synthetic filename, and the retained TypeScript diagnostic in one test. Sidecar +root bootstrap still succeeds because guest permissions are applied to guest +operations, not trusted base construction. + +### Relative cwd resolves once + +In the same integration file, create +`/workspace/project/{tsconfig.json,src/index.ts}` and assert: + +```ts +await vm.mkdir("/workspace/project/src", { recursive: true }); +await vm.writeFile( + "/workspace/project/tsconfig.json", + JSON.stringify({ + compilerOptions: { module: "commonjs", target: "es2022" }, + include: ["src/**/*.ts"], + }), +); +await vm.writeFile( + "/workspace/project/src/index.ts", + "export const value: number = 7;\n", +); +await expect(tools.typecheckProject({ cwd: "project" })).resolves.toEqual({ + success: true, + diagnostics: [], +}); +``` + +The parent fails: native resolves the process cwd from root rather than the VM +cwd, and the compiler then reapplies `project`. The fixed test proves the client +forwards the string, native sidecar resolves `/workspace/project`, and the guest +compiler trusts `process.cwd()` without a second resolution. + +### Browser parity + +In +`crates/native-sidecar-browser/tests/wire_dispatch.rs::browser_wire_dispatcher_handles_lifecycle_and_execution_frames`: + +- include `/workspace/project` as a directory in the bootstrap entries; +- change the execution request's current absolute cwd at line 1242 to + `Some(String::from("project"))`; and +- change the later process-snapshot cwd assertion at current line 1331 to + `/workspace/project`. + +That desired assertion fails on the parent because browser records `project` +verbatim. Afterward it proves browser uses the same shared Linux rule. + +The existing shared guest filesystem test at +`crates/native-sidecar-core/src/guest_fs.rs:587-610` already characterizes +relative join, `.`/`..` normalization, and empty-path `ENOENT`. Extend it or add +a focused direct `resolve_guest_path` test when making the function public; do +not copy fixtures into native and browser helpers. + +## After tests and validation + +Keep the existing absolute `/root` project cases in +`typescript-tools.integration.test.ts`; they prove explicit absolute overrides +still work. Rename `uses the caller-owned VM and removes its temporary runner +files` to `uses the caller-owned VM without temporary runner files`; retain its +caller-owned `/tmp/caller-owned.txt` and empty `agentos-typescript-*` assertions. + +Run: + +```sh +pnpm --dir packages/typescript exec vitest run \ + tests/typescript-tools.integration.test.ts +pnpm --dir packages/typescript check-types +pnpm --dir packages/typescript build +pnpm --dir packages/typescript test:smoke + +cargo test -p agentos-native-sidecar-core resolves_guest +cargo test -p agentos-native-sidecar-browser --test wire_dispatch \ + browser_wire_dispatcher_handles_lifecycle_and_execution_frames -- --exact +cargo test -p agentos-native-sidecar --lib +cargo check -p agentos-native-sidecar -p agentos-native-sidecar-browser + +pnpm --dir packages/secure-exec-example-ai-agent-type-check check-types +pnpm --dir packages/core exec vitest run tests/kernel-bootstrap-base.test.ts +cargo fmt --check +git diff --check +``` + +Final absence checks: + +```sh +! rg -n '__secure_exec_typescript_input__|options\.cwd \?\?

Mark completion only +after the dedicated jj revision and focused gates pass. + +## CI impact + +No workflow YAML or `scripts/ci.sh` edit is needed: + +- regular CI runs workspace TypeScript build/check-types and `pnpm test`, which + cover the compiler package and the example's newly chained docs verifier; +- regular Rust CI runs workspace clippy with all targets, compiling every + changed shared/native/browser Rust test target; +- `scripts/ci.sh` runs the same workspace clippy plus TypeScript workspace + checks; and +- nightly `cargo test --workspace` runs the shared/native/browser Rust tests. + +The focused shared, native, and browser commands remain mandatory before sealing +because regular GitHub/local CI compile these crates but do not explicitly run +their test packages. Adding workflow steps solely for this bounded cwd change is +unnecessary while focused validation and nightly own the behavioral tests. + +## Dependencies, risks, and non-goals + +- **Stack order:** Item 42 must be one revision on top of completed Item 41. +- **Item 43:** the next item retains implemented process `cwd` options, and its + research explicitly excludes the TypeScript `filePath` examples. Preserve + this item's cwd contract when rebasing; no direct path overlap is expected. +- **Item 49:** later example dependency cleanup touches the same example package + but not this source behavior. Preserve the scoped docs-verifier wiring. +- **Fixed argv size:** only the fixed generated runner is passed to `node -e`; + user source/request JSON is stdin. Do not interpolate user source into argv. +- **Bounded stdin:** rely on the existing sidecar process-input bounds and typed + failures. Do not add an unbounded client buffer or fallback temp file. +- **Functional filesystem access remains:** project typecheck reads files and + project emit may create output directories/write outputs. Item 42 removes + transport/bootstrap writes, not caller-requested compiler I/O. +- **Missing cwd:** an explicit nonexistent or empty cwd should fail through + normal process/POSIX behavior. Do not create it in the client or compiler. +- **Host-path compatibility:** native has an existing in-sandbox absolute host + cwd branch for runtime staging. Preserve it, but gate it to absolute input; + relative cwd is always guest-relative and must use the shared resolver. +- **No protocol feature:** stdin and optional execute cwd already exist. No BARE, + generated binding, Rust client, lockfile, or secure-exec mirror change is + required. +- **No TypeScript sidecar special case:** `/tmp`, cwd, and synthetic compiler + names must not be hard-coded into sidecar behavior. + +## Dedicated stacked jj revision + +Create exactly one revision on top of completed Item 41, keeping the existing +stack bookmark and shared working copy.

A real configurable limit would need one cross-adapter semantic +definition, including queued-byte accounting and both sides of the V8 codec. +That design does not exist today. Removing the false overrides is the smaller, +truthful thin-client behavior. Keep the implemented +`capturedOutputLimitBytes` override. + +Keep: + +- `env`, `cwd`, `timeout`, `onStdout` / `onStderr` on both exec and spawn; +- `stdin` and `captureStdio` on exec only; +- `streamStdin` on spawn, preserving `false`, `true`, and omission; +- every current `OpenShellOptions` field. `openShell` / `open_shell` is the + complete cross-client terminal API and already sends the sidecar's real + `ExecuteRequest.pty` descriptor. + +Do not add sidecar fields for the removed options. CPU policy already belongs to +VM-level `limits.jsRuntime.cpuTimeLimitMs`; `filePath` and timing mitigation +belong to the separate inline-code browser runtime; host fd inheritance has no +defined meaning across a sidecar boundary; and raw spawn already exposes stdin +and output as explicit process-handle routes. + +Do not remove `ExecuteRequest.pty` from the wire. TypeScript and Rust both use it +through `openShell`, which supplies stdin, EOF, output, resize, signals, and wait. +The TypeScript-only raw-spawn option exposes only initial dimensions and no +process-PTY resize operation, so removing that public duplicate is preferable to +adding the incomplete surface to Rust. + +Every removed common field is accepted by a public type but is not read by +either production serializer. The only one-client field (`pty`) has a complete +parity replacement already in both clients. + +## Scope of the inventory + +The direct public process option bags are: + +- TypeScript `ExecOptions`, `KernelSpawnOptions`, and `OpenShellOptions` in + `packages/core/src/runtime.ts`; +- Rust `ExecOptions` and `SpawnOptions` in `crates/client/src/process.rs`, plus + `OpenShellOptions` in `crates/client/src/shell.rs`. + +The follow-up compiler review also exposed the three inert VM-scoped JavaScript +limit overrides above. They appear in TypeScript `AgentOsLimits`, Rust +`JsRuntimeLimits`, the typed VM config, and the shared resolved-limit struct, +but have no consumer outside config parsing/validation. They are included here +because they are process-runtime options exposed by both clients and match the +same rule: remove unsupported input instead of making clients or adapters +pretend to honor it. + +The actor process actions expose only `env`, `cwd`, and `streamStdin`; all three +are honored. The actor has one Rust construction-site update after +`SpawnOptions` stops nesting `ExecOptions`, but its generated TypeScript action +contract does not change. + +The similarly named `ExecOptions` and `TimingMitigation` in +`packages/runtime-browser` are a different, inline-code execution API.

This is executable proof that the resolved values cannot reach the +runtime, not merely a repository-search inference. + +The limits audit currently compounds the false claim.

Do not delete the +real bounds. + +This is stronger than an omission bug in one client: both SDKs faithfully +forward values that the trusted runtime ignores. Implementing only the native +stdin field would create a new native/browser divergence, and implementing only +one IPC codec side would break framing. Remove all three unsupported overrides +from the public/config/resolved surfaces in this item.

Do not restore only the public fields. +- Host callbacks and process-route maps cannot move into the sidecar because + they refer to caller closures/subscriptions.

This note does not modify production +code, tests, or the Item 44 tracker status. + +Refreshed against the shared working tree on 2026-07-14. Priority: **P2**. +Confidence: **high**. + +## Recommendation + +Return the shared JSON-RPC method-not-found response from the native sidecar as +soon as an adapter sends an inbound method that is not one of the native ACP +filesystem, terminal, or permission methods. Delete the generic +`AcpHostRequestCallback` request/response variants and both client fallback +branches. + +There is no usable host-extension API to preserve. TypeScript always returns a +null response, Rust always returns `None`, and the browser sidecar already +returns `-32601` without involving a client. The current native round-trip can +therefore change only latency and failure mode, never the successful result. + +Keep the typed `AcpPermissionCallback`. Permission decisions are the one real +host-side operation in this path, and both clients have an explicit permission +handler for it. Also keep the native sidecar's internal +`NativeCoreCommand::InboundRequest` exchange: it is how the synchronous shared +ACP core reaches the sidecar's async filesystem, terminal, and permission +implementations. Item 44 removes the sidecar-to-client fallback, not that +sidecar-internal bridge. + +All producers and consumers of the dead callback are in this repository, both +clients decline it, the protocol ships in lockstep, and the canonical +sidecar-owned response already exists and is tested. + +## Original issue and exact current flow + +Line numbers below are from the shared working tree named above and may move as +earlier stack items land. + +An adapter-to-host JSON-RPC request is classified and answered by the shared ACP +core. `answer_inbound_request` in +`crates/agentos-sidecar-core/src/engine.rs:4525-4532` calls the host hook and +writes its returned JSON back to the adapter; its resumable exchange states call +that helper at lines 1672, 1818, 2187, and 2327. The blocking exchange path does +the same at `crates/agentos-sidecar-core/src/json_rpc.rs:93-98`. + +The default host implementation is already correct. At +`crates/agentos-sidecar-core/src/host.rs:81-90`, it calls +`unsupported_inbound_request_response`, which produces this canonical response +at `crates/agentos-sidecar-core/src/behavior.rs:49-65`: + +```json +{ + "jsonrpc": "2.0", + "id": "the original request id", + "error": { + "code": -32601, + "message": "method not found: host/not-found", + "data": { "method": "host/not-found" } + } +} +``` + +`BrowserAcpHost` implements `AcpHost` at +`crates/agentos-sidecar-browser/src/acp_host.rs:177-357` without overriding +`handle_inbound_request`, so it already uses that response. The production +browser-wrapper test is declared at +`crates/agentos-sidecar/tests/acp_wrapper_conformance.rs:84-93`; its +`run_browser_create` fixture at lines 2134-2215 proves that an inbound +`host/read` request receives `-32601`, preserves its ID and method, does not +complete the pending handshake, and never becomes a session event. + +Native ACP must override the hook because supported agent-to-host methods need +native facilities. `NativeCoreHost::handle_inbound_request` at +`crates/agentos-sidecar/src/acp_extension.rs:194-204` sends an internal +`NativeCoreCommand::InboundRequest`; the async broker handles it at lines +1151-1172. `build_inbound_response` at lines 1970-2075 then correctly routes: + +- `session/request_permission` to the typed client permission callback; +- `fs/read`, `fs/write`, and their aliases to the native filesystem handler; +- `terminal/*` to the native terminal handler; and +- every other method to `forward_inbound_host_request`. + +That last arm is the defect: + +```rust +_ => forward_inbound_host_request(ctx, session_id, message, &id)?, +``` + +`forward_inbound_host_request` at +`crates/agentos-sidecar/src/acp_extension.rs:2828-2859` serializes the complete +request into `AcpHostRequestCallback`, calls the client through +`ctx.invoke_callback(..., Duration::from_secs(120))`, decodes a generic JSON +response, and validates its ID. Only a decoded null/incorrect callback variant +is converted to the shared `-32601` response. + +More precisely, only a successfully decoded callback response whose generic +`response` field is absent (or whose union variant is not the generic host +variant) falls back to `-32601`. A missing transport, disconnected client, +write timeout, response timeout, malformed BARE/JSON response, or mismatched +JSON-RPC ID propagates as a sidecar error instead of method-not-found. + +### Authoritative wait chain + +The complete native wait is: + +1. `answer_inbound_request` in + `crates/agentos-sidecar-core/src/engine.rs:4525-4532` calls + `NativeCoreHost::handle_inbound_request` while the core is already waiting + for the adapter's enclosing create/resume/prompt response. +2. `NativeCoreHost::exchange` in + `crates/agentos-sidecar/src/acp_extension.rs:137-151` sends + `NativeCoreCommand::InboundRequest` and blocks on its one-shot sync channel. +3. The async native broker arm at + `crates/agentos-sidecar/src/acp_extension.rs:1151-1172` calls + `build_inbound_response`; its unknown arm calls + `forward_inbound_host_request`. +4. `ExtensionContext::invoke_callback` delegates through + `ExtensionSnapshot::invoke_callback` at + `crates/native-sidecar/src/extension.rs:289-299,370-376`. +5. `SharedSidecarRequestClient::invoke` at + `crates/native-sidecar/src/state.rs:260-283` allocates a request ID, sends a + `SidecarRequestFrame`, and requires matching ownership and request ID. +6. The stdio transport registers the waiter before emitting the frame, then + waits for the matching response until the supplied deadline at + `crates/native-sidecar/src/stdio.rs:1781-1933`. + +Unlike the retained permission path, this generic callback uses +`invoke_callback`, not `invoke_callback_cancellable`, and has no entry in +`permission_waits`. An interrupt therefore has no callback-specific +cancellation handle. Item 34's per-owner cores prevent this wait from taking a +different owner down with it, but the exact owner's ACP transition and adapter +response remain blocked until the callback answers or the 120-second deadline +fails. + +Both clients guarantee that the callback has no useful result: + +- TypeScript `_handleAcpExtSidecarRequest` at + `packages/core/src/agent-os.ts:2834-2876` decodes the callback and its + `AcpHostRequestCallback` arm always sends + `AcpHostRequestCallbackResponse { response: null }`. +- Rust `handle_acp_ext_callback` at + `crates/client/src/agent_os.rs:1316-1320` always sends the equivalent + `response: None`. + +No public registration method, handler map, or method-keyed extension API feeds +either branch. Registered host tools are a separate explicit tool surface and +must not make arbitrary ACP JSON-RPC methods callable. + +The result is a client round-trip with a 120-second failure window solely to +obtain the answer the sidecar already knows. A disconnected, blocked, malformed, +or mismatched client response can turn an ordinary unsupported method into a +timeout or sidecar error. Native and browser also behave differently even +though both ultimately reject the same request. + +## Exact production edits + +### `crates/agentos-sidecar/src/acp_extension.rs` + +1. Replace the unknown-method arm in `build_inbound_response` with the shared + response: + + ```rust + _ => unsupported_inbound_request_response(message), + ``` + + Do not add a second method-not-found constructor. The shared helper preserves + the request ID and returns the same error shape as the browser host. + +2. Delete `forward_inbound_host_request` completely. + +3. Remove the now-unused `AcpHostRequestCallback` import. + +4. Delete `json_rpc_id_label` and `parse_json_text`. Repository search shows + both helpers exist only for the deleted generic response and ID validation. + +5. Remove the `AcpHostRequestCallbackResponse` arm from + `permission_callback_reply`. After the protocol cleanup, the callback + response union contains only `AcpPermissionCallbackResponse`; simplify the + function to unwrap that one variant and preserve the existing missing-reply + default of `reject`. + +Do not delete `NativeCoreHost::handle_inbound_request`, +`NativeCoreCommand::InboundRequest`, the async broker arm, or any supported +filesystem/terminal/permission case. Moving the supported-method list into the +synchronous host just to avoid the internal exchange would duplicate routing +policy and is outside this item. + +### `crates/agentos-sidecar-core/src/codec.rs` + +Delete the unused public `encode_callback` helper at current lines 25-28 and +remove `AcpCallback` from the line-6 import. No production caller uses this +shared encoder: browser has no client callback transport, while native owns its +permission callback encoding inside `acp_extension.rs`. Leaving it would retain +a generic callback API after the generic callback itself is gone. + +### `crates/agentos-protocol/protocol/agent_os_acp_v1.bare` + +At current lines 270-304, delete these dead wire structs: + +```text +AcpHostRequestCallback +AcpHostRequestCallbackResponse +``` + +Remove their arms from `AcpCallback` and `AcpCallbackResponse`, leaving the +typed permission variants as single-arm unions: + +```bare +type AcpCallback union { + AcpPermissionCallback +} + +type AcpCallbackResponse union { + AcpPermissionCallbackResponse +} +``` + +The TypeScript BARE generator accepts these single-arm unions. Keeping the +permission arm at tag zero also leaves the permission callback's encoded bytes +unchanged. Do not retain a dead reserved arm: the project has no protocol +backward-compatibility guarantee and clients/sidecar ship in lockstep. + +### Generated TypeScript protocol + +Run: + +```sh +pnpm --dir packages/core build:agentos-protocol +``` + +This regenerates `packages/core/src/sidecar/agentos-protocol.ts`. Do not hand +edit it. The affected current generated block is lines 1223-1407. It should no +longer export readers, writers, types, or union cases named +`AcpHostRequestCallback` or +`AcpHostRequestCallbackResponse`. + +Rust protocol code is generated into Cargo `OUT_DIR` by +`crates/agentos-protocol/build.rs`; there is no checked generated Rust source to +edit. + +### `packages/core/src/agent-os.ts` + +Delete the `case "AcpHostRequestCallback"` branch from +`_handleAcpExtSidecarRequest`. With the regenerated one-variant type, keep only +the typed permission decoding, handler call, and response encoding. + +It is safe, and simpler, to remove the switch and read the sole generated +variant's `val` directly. Do not add a generic JSON request handler or a client +method-not-found fallback. An unknown adapter method must never reach this +function after the sidecar change. + +### `crates/client/src/agent_os.rs` + +Remove the `AcpHostRequestCallbackResponse` import and the +`AcpCallback::AcpHostRequestCallback` match arm. Destructure the sole +`AcpPermissionCallback` variant and retain the current typed permission routing +and response. + +Do not remove the ACP extension callback handler itself. Rust still needs it to +answer explicit permission requests. + +### Existing guidance + +No guidance edit is required for Item 44. `packages/core/CLAUDE.md:57` already +states that native filesystem and terminal methods execute in the sidecar, +unknown methods return `-32601`, and clients must not recreate a generic ACP +request dispatcher. The implementation should make that existing rule true. + +## Before validation + +Use the existing native integration path in +`crates/agentos-sidecar/tests/acp_extension.rs:186-281`, not a mock of +`unsupported_inbound_request_response`. The JavaScript adapter is +`terminal_adapter_script` at lines 1403-1507. + +`acp_terminal_requests_stay_inside_sidecar` already has an adapter fixture that +runs supported terminal methods and then sends: + +```json +{"jsonrpc":"2.0","id":105,"method":"host/not-found","params":{}} +``` + +Its current host callback handler explicitly decodes +`AcpHostRequestCallback`, asserts the method is `host/not-found`, returns +`response: None`, and thereby allows the prompt to receive `-32601`. Despite +the test's message saying the request must not reach the client, the test +currently requires that client callback to complete. + +Before changing production code, make the characterization explicit: + +1. capture an `Arc` in the callback handler; +2. increment it after decoding the `host/not-found` callback; +3. keep returning `response: None`; and +4. assert the count is exactly one after the prompt completes. + +Run that test against Item 44's parent revision and record its name and parent +revision in the tracking checklist. It deterministically proves the generic +host callback was emitted. The production call to `invoke_callback` proves the +request is synchronously waiting for that response; do not add a flaky elapsed +time assertion merely to restate the 120-second code path. + +The suite currently passes on the parent (`acp_extension_suite`, plus its bridge +support test). The browser method-not-found test and both shared-core canonical +response/exchange tests also pass. Record the dedicated callback count after +adding it; the existing pass alone does not quantify the callback. + +## After validation + +In the same integration test, replace the characterization handler with one +that increments the counter and immediately returns +`agentos_native_sidecar::SidecarError::InvalidState("unexpected ACP client callback".into())`. +The adapter's `host/not-found` request must still complete and the counter must +remain zero. This makes a regression fail immediately instead of waiting 120 +seconds; a bare no-handler setup would prove completion but not explicitly +prove callback absence. + +Extend `terminal_adapter_script` to return the complete unknown-method response +inside its prompt result, then assert: + +- response ID is `105`; +- `error.code` is `-32601`; +- `error.message` is `method not found: host/not-found`; +- `error.data.method` is `host/not-found`; and +- the client callback count is zero. + +Retain the existing terminal output/exit/truncation assertions in the same test. +They prove that supported native host methods still use the sidecar handlers +while only the unknown fallthrough changed. Rename the test to something +explicit such as +`acp_terminal_and_unknown_host_requests_stay_inside_sidecar` if useful. + +The existing `acp_extension_creates_reports_and_closes_session_over_ext` test +must continue to exercise a real typed permission callback. Remove only its now +impossible generic-host match arm. Do the same in +`install_default_acp_callback_handler`. + +Add small protocol round-trip coverage so deleting the dead arm cannot +accidentally damage the retained callback: + +- in `crates/agentos-protocol/tests/roundtrip.rs`, round-trip an + `AcpPermissionCallback` and `AcpPermissionCallbackResponse` through BARE; +- in `packages/core/tests/agentos-protocol.test.ts`, round-trip the same + permission request/response with the generated TypeScript ACP codec.

The complete inventory is: + +1. `crates/sidecar-protocol/src/protocol.rs:1883-2054` defines + `NativePayloadCodec::{Json,Bare}` and `NativeFrameCodec`. Its decoder sniffs + the first byte and tries an alternate decoder. The only consumers are + `crates/native-sidecar/tests/protocol.rs` and + `crates/native-sidecar/tests/generated_protocol.rs`. +2. `crates/sidecar-protocol/src/wire.rs:134-157` defines + `CreateVmRequest::legacy_test_config`. It has **23 direct call sites across + 13 native-sidecar test files** and no production caller. Shared and local + metadata helpers expand that to dozens of fixture invocations. It delegates + to a roughly 500-line parser of string keys such as + `resource.max_processes` and `env.NAME`. +3. `packages/runtime-core/src/frame-payload-codec.ts:1-25` is a second JSON + codec. `packages/runtime-core/src/protocol-frames.ts:91,200-217` makes JSON + versus BARE a production/public choice. +4. That TypeScript choice propagates through native stdio and synchronous browser + APIs as `payloadCodec?` or `codec?`. It is also published as the + `@rivet-dev/agentos-runtime-core/frame-payload-codec` subpath. +5. The real sidecars do not negotiate or decode JSON.

The actual WASM sidecar accepts BARE only. | + +The only string metadata keys still used by those Rust fixtures are: + +```text +cwd +env.AGENTOS_ALLOWED_NODE_BUILTINS +env.AGENTOS_KEEP_STDIN_OPEN +env.AGENTOS_LOOPBACK_EXEMPT_PORTS +env.VISIBLE_MARKER +env.WORKTREE +limits.http.max_fetch_response_bytes +network.dns.override.example.test +network.dns.override.metadata.test +network.dns.servers +resource.cpu_count +resource.max_pread_bytes +resource.max_processes +resource.max_sockets +resource.max_wasm_fuel +resource.max_wasm_memory_bytes +``` + +Everything else recognized by `legacy_dns_config`, +`legacy_native_root_config`, `legacy_listen_config`, and +`legacy_limits_config` is already dead fixture grammar.

The repository contract +says the protocol, clients, and sidecars release in lockstep with no wire +backward-compatibility guarantee. + +## Root cause + +This is unfinished migration scaffolding, not a sidecar capability. The real +native and browser entrypoints moved to generated `WireFrameCodec`/BARE, but the +older handwritten Rust codec was left publicly exported for compatibility +tests. TypeScript then retained a matching public codec selector so JSON fake +sidecars could keep working. Separately, native tests kept constructing VM +configuration through the pre-typed string metadata map, which caused its +roughly 500-line parser to remain compiled into the production protocol crate. + +Nothing on a real same-version connection negotiates these choices. Moving the +old codecs or metadata parser into the sidecar would therefore add behavior; +the correct fix is to migrate the fixtures and delete the compatibility paths. + +## What must remain client-side + +This item removes alternate behavior, not transport itself. Keep these client +responsibilities: + +- four-byte big-endian length framing and generated BARE encode/decode; +- conversion between ergonomic TypeScript request/response objects and the + generated positional BARE types; +- validation and serialization of explicit caller input; +- routing host callbacks/events and retaining host-only correlation state; +- TypeScript Zod tool-schema construction and the package-manager default + package exception, neither of which is related to this item. + +Keep `encodeBareProtocolFrame`, `decodeBareProtocolFrame`, and +`toGeneratedProtocolFrame` in +`packages/runtime-core/src/protocol-frames.ts:155-198`. Keep Rust +`wire::WireFrameCodec` at `crates/sidecar-protocol/src/wire.rs:815-925`. + +Also keep JSON text that is an explicitly typed value *inside* a BARE frame. +`crates/sidecar-protocol/protocol/agentos_sidecar_v1.bare:5,167-170` defines +`JsonUtf8` and `CreateVmRequest.config: JsonUtf8`. +`CreateVmRequest::json_config` at `wire.rs:124-132` serializes typed +`CreateVmConfig` into that field. ACP JSON-RPC, tool schemas/results, extension +payloads, and other `JsonUtf8` values remain. Consequently `serde_json` remains +a real dependency.

This note does not modify +production code, tests, or the Item 46 tracker status. + +## Recommendation + +Make each Rust request option that maps to an optional TypeScript/protocol field +presence-aware, then forward the `Option` without inspecting its effective +value. The concrete collapses are: + +1. VM `root_filesystem`, nested `disable_default_base_layer` / `lowers`, and + `loopback_exempt_ports`; +2. process and shell `env`; +3. create/resume-session `env`, create-session `mcp_servers` and + `skip_os_instructions`, plus optional fields inside MCP descriptors; +4. filesystem `recursive` for mkdir/delete; +5. actor-plugin DTOs that currently deserialize those fields into empty maps, + empty lists, or `false` before calling the Rust client. + +Use `Option` at the Rust boundary. `None` means omitted; `Some(empty)` and +`Some(false)` mean exactly what the caller supplied. Do not add sidecar defaults +or change BARE/protocol types: all relevant wire fields are already optional. + +Two TypeScript wire-boundary corrections are also required. ACP create must use +`skipOsInstructions: options?.skipOsInstructions ?? null`, and +`SidecarProcess.execute` must test `env`/`cwd` with `!== undefined` +instead of value truthiness. The high-level TS process client retains `{}` and +`""`, but the final runtime-core serializer currently drops them immediately +before encoding the request. TypeScript already preserves explicit +empty/default values for the other surfaces in scope. + +Priority: **P1 overall** (**P1** actor-root behavior, **P2** remaining parity +collapses). Recommended-fix confidence: **high**. The conversion is a +mechanical `Option` migration and every destination wire field is already +optional. The actor root bug is already observable: explicit +`rootFilesystem: {}` selects the actor's native durable root instead of the +requested overlay. Process/session env and filesystem recursion have the same +effective behavior for omitted and explicit empty/false values today, but +leaving them would retain the same proven representation bug and cross-client +mismatch. + +## Original issue and observable impact + +Rust uses value-bearing defaults where TypeScript uses optional fields, then +tries to infer presence by inspecting values: + +```rust +root_filesystem != RootFilesystemConfig::default() +!loopback_exempt_ports.is_empty() +disable_default_base_layer.then_some(true) +!lowers.is_empty() +!env.is_empty() +skip_os_instructions.then_some(true) +recursive.then_some(true) +``` + +That inference is impossible. For example, these caller intents become the same +Rust value and absent wire payload: + +```rust +AgentOsConfig::default() + +AgentOsConfigBuilder::new() + .root_filesystem(RootFilesystemConfig::default()) + .loopback_exempt_ports(vec![]) + .build() +``` + +TypeScript instead distinguishes `AgentOs.create({})` from +`AgentOs.create({ rootFilesystem: {}, loopbackExemptPorts: [] })`. Its root, +loopback, ACP env/MCP, and filesystem serializers already preserve that +distinction. The two TS exceptions found in this audit are ACP +`skipOsInstructions: false` and final process `env: {}` / `cwd: ""` encoding; +they are included below so Item 46 ends with actual wire parity. + +The actor root is already an observable semantic failure. The actor installs its +durable `js_bridge` native root only when the caller omitted `rootFilesystem`, +but currently compares the resolved value to `RootFilesystemConfig::default()`. +Explicit `rootFilesystem: {}` is therefore mistaken for omission and replaced +with the actor database root. + +Other sidecar defaults currently make omission and explicit empty/false behave +the same. They still must cross separately: the clients ship in lockstep, and a +future sidecar default must not silently affect only TypeScript. + +## Current-stack code proof + +The current stack still contains every collapse.

Update direct literals in +`session_e2e.rs`, `os_instructions_e2e.rs`, and `pi_session_e2e.rs`. +Extract the create/resume field projection into small pure helpers if needed so +the presence matrix can be tested without booting a sidecar; those helpers must +only serialize, never resolve defaults. + +In `crates/client/src/cron.rs`, give `WireCreateSessionOptions` the same optional +fields and `skip_serializing_if = "Option::is_none"` on every optional field. +Then `options: Some(Default::default())` serializes as `"options": {}` like TS, +instead of materializing null/empty/false fields. Keep both conversions lossless. + +### 5. Filesystem recursion + +In `crates/client/src/fs.rs`: + +```rust +pub struct MkdirOptions { pub recursive: Option } +pub struct DeleteOptions { pub recursive: Option } +``` + +Have `kernel_mkdir` / `kernel_remove_path` accept `Option` and assign it +directly to `GuestFilesystemCallRequest.recursive`. Update `fs_e2e.rs` to wrap +explicit true/false values. + +### 6. Actor action DTOs + +Generated TypeScript actor interfaces already mark these fields optional, but +serde erases presence. Update: + +- `actions/process.rs`: optional env on exec/spawn DTOs, forwarded directly; +- `actions/shell.rs`: optional env, forwarded directly; +- `actions/session.rs`: optional env and skip flag, forwarded directly; +- `actions/filesystem.rs`: wrap actor-supplied recursion in `Some(...)`. + +Regenerate/check `packages/agentos/src/generated/actor-actions.generated.ts`. +It should remain byte-for-byte unchanged. Do not hand-edit generator output. + +### 7. TypeScript parity corrections + +In `packages/core/src/agent-os.ts`, replace: + +```ts +skipOsInstructions: + options?.skipOsInstructions === true ? true : null, +``` + +with: + +```ts +skipOsInstructions: options?.skipOsInstructions ?? null, +``` + +No further TS production edit is needed. Existing code already preserves the +other explicit empty/default inputs. The process `env`/`cwd` correction belongs +in `packages/runtime-core/src/sidecar-process.ts` as described in section 3; +fixing only `rpc-client.ts` would be ineffective because that layer already +retains the values. + +## Before and after tests + +### Before behavior to record + +Add focused regressions against the parent before production edits. The +minimum tracker proof should be a failing expectation, not only a +characterization that confirms two payloads are equal: + +1. `agent_os.rs`: + `create_vm_config_preserves_explicit_default_presence` constructs the config + through `AgentOsConfigBuilder::root_filesystem(RootFilesystemConfig::default())` + and `.loopback_exempt_ports(vec![])`, then expects + `rootFilesystem: {}` and `loopbackExemptPorts: []`. It fails on the current + parent because both keys are absent. A companion characterization may assert + that this payload is currently identical to `AgentOsConfig::default()`. +2. `process.rs`: the current request builder maps an explicit empty env to + `None`; omission cannot be represented. +3. `session.rs`: a pure ACP request builder shows empty env/MCP and false skip + becoming `None`. +4. `fs.rs`: a pure guest-fs builder shows false recursive becoming `None`. +5. actor `config.rs`/`vm.rs`: omitted and explicit `{ rootFilesystem: {}, + loopbackExemptPorts: [] }` converge, and explicit `{}` is eligible for actor + native-root replacement. +6. `packages/runtime-core/tests/sidecar-process.test.ts`, beside + `preserves false, true, and omission for keepStdinOpen`: the final Execute + payload currently omits explicit `env: {}` and `cwd: ""`. The same in-memory + transport can capture mkdir/remove omission versus explicit false without a + sidecar binary. +7. `packages/core/tests/session-route-registration.test.ts`: extend + `createInjectedAgent` to retain the ACP request envelope and decode it with + `decodeAcpRequest`; `skipOsInstructions: false` currently becomes null while + explicit empty env/MCP remain present. + +Use the parent result as before evidence, then replace collapse assertions with +the after matrix in the same item revision. + +### After matrix + +- `crates/client/src/agent_os.rs`: + `create_vm_config_preserves_omitted_and_explicit_default_presence` checks + default absent, explicit overlay `{}`, explicit false, empty lowers, and empty + loopback. +- `crates/client/src/process.rs`: check env `None` versus `Some(empty)`. +- `crates/client/src/shell.rs`: extract a tiny pure request builder and check the + same env matrix without filling PTY dimensions. +- `crates/client/src/session.rs`: create/resume request tests check absent, + empty, and false; MCP exact JSON includes local `{ args: [], env: {} }` and + remote `{ headers: {} }`. +- `crates/client/src/cron.rs`: extend + `session_action_wire_shape_matches_typescript` with `options: {}` and explicit + empty/false cases. +- `crates/client/src/fs.rs`: check recursive `None`, `Some(false)`, `Some(true)`. +- actor `config.rs`/`vm.rs`: omitted root gets actor `js_bridge`; explicit `{}` + stays overlay; omitted/empty loopback remain distinct. +- retain `packages/core/tests/root-filesystem-descriptors.test.ts`'s + `does not materialize omitted sidecar defaults` test as the TypeScript root + reference: it already distinguishes `{}` from explicit false/empty fields. +- extend `packages/core/tests/session-route-registration.test.ts` at the + injected ACP boundary: absent fields decode as null, explicit `{}` / `[]` / + `false` decode as an empty map / `"[]"` / false. This is closer to the actual + caller than the codec-only `agentos-protocol.test.ts` fixture. +- extend `packages/runtime-core/tests/sidecar-process.test.ts` at the final + `SidecarProcess.execute` seam: absent env/cwd omit keys, `{}`/`""` retain + keys, and a nonempty value remains unchanged. Use its existing + `MemorySidecarTransport.requests` fixture. In the same file, call + `mkdir`/`removePath` with omitted, false, and true recursion and inspect the + captured `guest_filesystem_call` payloads. +- extend `packages/agentos/tests/actor.test.ts` so `buildConfigJson` omits absent + root/loopback and retains explicit `{}` / `[]`. + +Existing lower-layer tests cover adjacent behavior but not the collapse: + +```text +cargo test -p agentos-vm-config \ + root_filesystem_preserves_omission_and_explicit_default_overrides +pnpm --dir packages/core exec vitest run \ + tests/root-filesystem-descriptors.test.ts --reporter=verbose +cargo test -p agentos-client --lib root_filesystem_serializer +``` + +The root tests cover sidecar defaults and nonempty/true descriptors; they do not +compare omission with explicit empty/false input.

Replace inference in the pure Rust wire projections. Extract only the small + session/shell/fs request builders needed for unit tests; do not move policy or + add effective defaults. +4. Mirror the new options through actor config/action DTOs. Fix the root choice + using the outer `Option` preserved by `to_agent_os_config`; keep actor mkdir + explicitly recursive with `Some(true)`. +5. Apply the two TS serializer corrections and extend the existing in-memory + fixtures. No new transport abstraction or sidecar behavior is required. +6. Update cron's JSON mirror, run actor contract generation/checks, and confirm + generated protocol and actor TypeScript surfaces are unchanged. +7.

A lease should contain only: + +- the public `AgentOsSidecar` handle; +- the real VM admin, which already contains the authoritative wire session and + sidecar VM identities; and +- an idempotent, retryable `dispose()` that releases that admin and then updates + the host-owned lease set/refcount. + +Retain `AgentOsSidecarState.activeLeases`, `activeVmCount`, the shared process +handle, and the Node event-loop hold count. Those are legitimate host ownership +and pooling state that the sidecar cannot manage for the Node process. Remove the +second session/VM state machine, UUIDs, timestamps, cloned lifecycle records, +and VM-admin map. + +Do not add a sidecar RPC for this.

Confidence: **medium**, matching the tracker (approximately +0.75 for the complete implementation, although the architectural diagnosis is +high confidence). The deletion and direct replacement are mechanically clear +and the real VM admin already owns the correct disposal operation. The +implementation rating stays medium because shared-process ref/unref, retryable +disposal, creation failure, and sibling-VM isolation are subtle and must retain +their current integration coverage. + +## Original issue and current behavior + +Line numbers below are from the inspected shared working copy and may move before +Item 47 is implemented. + +### The authoritative VM already exists + +`AgentOs.create()` builds `createVmAdmin` at +`packages/core/src/agent-os.ts:1406-1559`. That function: + +1. obtains the real shared `SidecarProcess` and authenticated wire session; +2. sends `initializeVm` at lines 1477-1485; +3. receives the sidecar-generated `nativeVm.vmId` and authoritative guest + initialization result, including cwd/env; +4. constructs `NativeSidecarKernelProxy` with the real connection/session/VM + ownership; and +5. returns `AgentOsVmAdmin`, which contains `sidecarClient`, `sidecarSession`, + `sidecarVm`, and an admin `dispose()` that ultimately invokes the real + sidecar VM disposal. + +`NativeSidecarKernelProxy.dispose()` at +`packages/core/src/sidecar/rpc-client.ts:278-369` is authoritative and retryable: +it calls `client.disposeVm(session, vm)` first and only tears down local routes +after the sidecar accepts the remote disposal. With `ownsClient: false`, it +correctly leaves the shared sidecar process alive for sibling VMs. + +Nothing else is required to identify or own the VM. + +### A synthetic lifecycle is then wrapped around it + +Despite already having the real admin, `leaseAgentOsSidecarVm` at +`packages/core/src/agent-os.ts:3544-3640` creates an +`AgentOsSidecarClient` from `packages/core/src/sidecar/rpc-client.ts`. + +That class, at `rpc-client.ts:1106-1448`, manufactures a second lifecycle: + +- `AgentOsSidecarSessionState` and `AgentOsSidecarVmState` state machines; +- `AgentOsSidecarSessionLifecycle` and `AgentOsSidecarVmLifecycle` timestamped + records; +- random session and VM IDs from `randomUUID`; +- a `sessions` map containing per-session VM maps; +- session and VM handle classes with `describe`, `listVms`, and `dispose`; +- transport bootstrap types carrying the invented IDs; and +- cloning/error bookkeeping used only by that synthetic state. + +Production then adapts the real admin into that abstraction through +`createInProcessSidecarTransport` at `agent-os.ts:3642-3716`: + +```text +synthetic session id + -> synthetic VM id + -> vmAdmins Map lookup by synthetic VM id + -> real AgentOsVmAdmin + -> real sidecar session id + real sidecar VM id +``` + +The synthetic IDs are not sent to the sidecar and are unrelated to +`nativeVm.vmId` or the real authenticated session. The production lease keeps +both synthetic handles only so `client.dispose()` can traverse its maps and +eventually call `admin.dispose()`. + +The complete production sequence is currently: + +```ts +const client = createAgentOsSidecarClient(...); +const session = await client.createSession(...); // invent UUID +const vm = await session.createVm(); // invent another UUID +const admin = transport.getVmAdmin(vm.vmId); // recover real admin +``` + +This is client-owned runtime emulation, not transport forwarding or necessary +host callback state. + +### The standalone tests prove only the manufactured model + +`packages/core/tests/sidecar-client.test.ts` directly constructs the synthetic +class with fake transports. Its first test injects `id-1`/`id-2` and fake clock +ticks, then asserts the invented lifecycle records and maps. Its second test +creates multiple fake sessions/VMs and checks traversal order. Its third test +checks retry on the fake session transport. + +Those tests do not cross the sidecar protocol and do not validate a real VM. +They preserve the abstraction Item 47 is meant to remove. + +The unchanged before-characterization was executed on the inspected working +copy: + +```text +pnpm --dir packages/core exec vitest run tests/sidecar-client.test.ts +Test Files 1 passed (1) +Tests 3 passed (3) +``` + +## Why direct leasing is the right boundary + +The host still needs to know how many `AgentOs` instances lease one shared +child process, whether the handle is disposing, and when Node child/stdio +handles can be `ref()`/`unref()`ed. That is why these fields in +`AgentOsSidecarState` remain valid: + +- `activeLeases` and the derived public `activeVmCount`; +- `nativeProcess` and `sharedChild`; +- `eventLoopHolds`; +- shared-pool identity; and +- the handle's ready/disposing/disposed state. + +The sidecar owns actual session/VM IDs and runtime cleanup. The real admin owns +the minimum host adapters tied to that VM. No second lifecycle registry is +needed between them. + +The Rust SDK already follows this conceptual boundary. Its +`AgentOsSidecarVmLease` in `crates/client/src/sidecar.rs:281-310` retains the +actual sidecar handle and decrements host lease accounting only after +authoritative shutdown. It has no synthetic session ID, VM ID, timestamped +lifecycle map, or transport adapter map. + +## Exact production edits + +### `packages/core/src/sidecar/rpc-client.ts` + +Current exact anchors are `AgentOsSidecarPlacement` at lines 1102-1104; the +synthetic lifecycle block from `AgentOsSidecarSessionState` through +`createAgentOsSidecarClient` at lines 1106-1448; and its clone helpers at lines +1517-1549. `toErrorMessage` is at lines 1589-1591. + +Delete the complete synthetic lifecycle surface: + +- `AgentOsSidecarSessionState`; +- `AgentOsSidecarVmState`; +- `AgentOsSidecarSessionLifecycle`; +- `AgentOsSidecarVmLifecycle`; +- `AgentOsSidecarSessionOptions`; +- `AgentOsSidecarSessionBootstrap`; +- `AgentOsSidecarVmBootstrap`; +- `AgentOsSidecarTransport`; +- `AgentOsSidecarClientOptions`; +- `AgentOsSidecarVmEntry`; +- `AgentOsSidecarSessionEntry`; +- `AgentOsSidecarVmHandle`; +- `AgentOsSidecarSessionHandle`; +- `AgentOsSidecarClient`; +- `createAgentOsSidecarClient`; +- `clonePlacement`, `cloneSessionLifecycle`, and `cloneVmLifecycle`; and +- `toErrorMessage`, which is used only to populate the deleted fake lifecycle. + +Remove the now-unused `randomUUID` import from this file. Keep `toError`: the +real `NativeSidecarKernelProxy` disposal path uses it. + +Keep `AgentOsSidecarPlacement` for now because `agent-os.ts` uses it for the +public sidecar description/config shape. Moving that type is not required to +remove lifecycle behavior and would broaden the public declaration diff. + +Do not touch the framed `SidecarProcess`, `NativeSidecarKernelProxy`, wire +serializers, or descriptor helpers in this file. + +### `packages/core/src/agent-os.ts` + +Current exact anchors are the synthetic imports at lines 140-150, the lease +shape at lines 181-202, the real `createVmAdmin` at lines 1411-1564, its lease +call at lines 1566-1572, legitimate host lease/process state at lines +3234-3269, the synthetic production lease at lines 3573-3669, and the admin-map +transport at lines 3671-3745. + +1. Remove imports for `AgentOsSidecarClient`, both synthetic bootstrap types, + both synthetic handle types, `AgentOsSidecarTransport`, and + `createAgentOsSidecarClient`. + +2. Rename the minimal local bound from `InProcessSidecarVmAdmin` to something + that describes the retained real host resource, such as + `DisposableSidecarVmAdmin`: + + ```ts + interface DisposableSidecarVmAdmin { + dispose(): Promise; + } + ``` + +3. Simplify `AgentOsSidecarVmLease` by deleting `session` and `vm`: + + ```ts + interface AgentOsSidecarVmLease< + TVmAdmin extends DisposableSidecarVmAdmin, + > { + sidecar: AgentOsSidecar; + admin: TVmAdmin; + dispose(): Promise; + } + ``` + +4. Delete `CreateInProcessSidecarTransportOptions`, + `InProcessSidecarTransport`, and `createInProcessSidecarTransport` in full. + Their only purpose is mapping synthetic IDs back to the real admin. + +5. Change `leaseAgentOsSidecarVm` to accept the real admin factory directly: + + ```ts + async function leaseAgentOsSidecarVm< + TVmAdmin extends DisposableSidecarVmAdmin, + >( + sidecar: AgentOsSidecar, + createVmAdmin: () => Promise, + ): Promise> + ``` + +6. Preserve the current ready-state check and acquire the shared-sidecar event + loop hold before awaiting VM creation. Then call only: + + ```ts + const admin = await createVmAdmin(); + ``` + + There must be no client/session/VM UUID generation and no admin lookup. + +7. Construct the lease around that `admin`. Its disposal sequence must remain: + + ```text + await admin.dispose() + mark lease disposed + delete the lease record + derive activeVmCount from activeLeases.size + release the event-loop hold exactly once + ``` + + Keep the current shared `disposePromise`/retry structure. If + `admin.dispose()` rejects, do not mark the lease disposed, remove it from + `activeLeases`, decrement `activeVmCount`, or release the hold. Clear only + the failed attempt promise so a later `AgentOs.dispose()` can retry. + +8. On creation failure, release the event-loop hold exactly once and rethrow. + `createVmAdmin` already owns rollback of a partially initialized real VM; do + not manufacture another transport cleanup pass. + +9. Change the call site at `AgentOs.create()` from: + + ```ts + leaseAgentOsSidecarVm(sidecar, { + createVm: async () => createVmAdmin(), + }) + ``` + + to: + + ```ts + leaseAgentOsSidecarVm(sidecar, createVmAdmin) + ``` + +Do not call `SidecarProcess.dispose()` from a VM lease. Each VM proxy has +`ownsClient: false`; the `AgentOsSidecar` handle owns the one shared process and +disposes it only after all real VM leases are gone. + +## Proposed small diff sequence + +Keep the implementation mechanically reviewable in this order: + +1. Add the red lease-shape characterization to + `packages/core/tests/sidecar-placement.test.ts` and record the parent failure: + the lease has the authoritative `admin`, but also exposes synthetic `session` + and `vm` fields. Run the unchanged synthetic unit suite and record its three + passing tests as removal evidence. +2. In `agent-os.ts`, change the lease factory parameter from the adapter-options + object to `createVmAdmin: () => Promise`, call it directly, retain + only `{ sidecar, admin, dispose }`, and make `dispose()` await + `admin.dispose()` before changing the host lease set/count/hold. +3. Still in `agent-os.ts`, delete `CreateInProcessSidecarTransportOptions`, + `InProcessSidecarTransport`, and `createInProcessSidecarTransport`, then + remove their imports and the synthetic lease fields. Do not refactor the + surrounding shared-sidecar pool or process lifecycle in this change. +4. In `rpc-client.ts`, delete the now-unreferenced manufactured lifecycle block, + clone helpers, `toErrorMessage`, and its `randomUUID` import. Keep + `AgentOsSidecarPlacement`, the real framed client/proxy, serializers, and + `toError`. +5. Delete `sidecar-client.test.ts`, make the red real-lease test green, add the + two-real-VM acceptance case, then run retry, sibling ownership, leak, and + clean-exit coverage unchanged. Finish with typecheck and the zero-reference + source inventory. + +That sequence is one bounded Item 47 revision; the intermediate red test is +evidence to record, not a separate committed revision. + +### No Rust, sidecar, protocol, or documentation edit + +This is a TypeScript host-lifecycle deletion. No wire field or sidecar behavior +changes, and Rust already uses direct lease accounting. The public +`AgentOsSidecar` API (`describe`, `activeVmCount`, shared/explicit placement, +and `dispose`) remains unchanged. + +`packages/core/CLAUDE.md:35` already states the correct boundary: framed I/O and +serializers live in `rpc-client.ts`, while shared/explicit pool and VM lease +bookkeeping live in `agent-os.ts`; neither layer owns runtime emulation or +policy. No guidance change is needed. + +## Before validation + +Before editing production code, add a focused regression to +`packages/core/tests/sidecar-placement.test.ts`, for example +`"retains only the authoritative VM admin in a host lease"`. Create a real VM +with an explicit sidecar ID, then use a typed test backdoor to inspect +`_sidecarLease`, `_sidecarVm`, and the lease admin: + +```ts +const internals = vm as unknown as { + _sidecarVm: CreatedVm; + _sidecarLease: { + admin: { sidecarVm: CreatedVm }; + session?: unknown; + vm?: unknown; + }; +}; + +expect(internals._sidecarLease.admin.sidecarVm).toBe(internals._sidecarVm); +expect(internals._sidecarLease).not.toHaveProperty("session"); +expect(internals._sidecarLease).not.toHaveProperty("vm"); +``` + +The first assertion proves the lease already retains the authoritative VM. The +last two assertions fail on Item 47's parent because the production lease also +contains the manufactured `AgentOsSidecarSessionHandle` and +`AgentOsSidecarVmHandle`. Record that exact failure before changing the +implementation. This is intentionally an internal-boundary regression: the +synthetic lifecycle has no legitimate public behavior to exercise. + +Also run `packages/core/tests/sidecar-client.test.ts` unchanged against Item +47's parent and record the revision and three passing test names in the +tracker. Those tests characterize exactly what is being removed: + +- injected UUIDs become session/VM identities; +- fake timestamps and lifecycle states are retained in nested maps; +- client disposal walks those maps to reach a fake transport; and +- retry is implemented at the fake session layer. + +Record the production source trace from `leaseAgentOsSidecarVm`: it creates +the class, calls synthetic `createSession`/`createVm`, and looks the real admin +back up by the invented VM ID. The standalone test alone does not prove +production usage; the red real-lease test plus this call-site trace does. + +Do not retain the old fake-lifecycle assertions after the implementation. They +would test deleted behavior rather than compatibility. + +## After validation + +Delete `packages/core/tests/sidecar-client.test.ts` after its before evidence is +recorded. Keep the new red lease-shape regression and make it pass by retaining +only `sidecar`, the authoritative `admin`, and `dispose` on the lease. Expand +the lifecycle acceptance around real public behavior in +`packages/core/tests/sidecar-placement.test.ts`: + +1. Create one explicit `AgentOsSidecar` and two real `AgentOs` VMs against it. +2. Assert `activeVmCount` changes `0 -> 1 -> 2` only as real VM creation + succeeds. +3. Read each test VM's existing private `_sidecarVm.vmId` through a typed test + backdoor and assert the authoritative IDs are non-empty and distinct. Do not + add a production getter merely for this assertion. +4. Perform guest I/O in both VMs to prove both real admins remain live. +5.

Preserve the per-lease `disposePromise`, + disposed flag, and one-shot hold release. +- **Creation failure:** the event-loop hold is acquired before asynchronous VM + creation, so every failure path must release it exactly once. Do not add a + synthetic failed-lifecycle tombstone. +- **Real identity:** host callback/event routing must continue using + `sidecarSession.connectionId`, `sidecarSession.sessionId`, and + `sidecarVm.vmId` from the real admin. No new local ID should replace them. +- **Session granularity:** TypeScript currently shares one real wire session + across VMs on a sidecar handle while VM ownership is separated by real + `vm_id`. Item 47 removes fake sessions but does not redesign that valid wire + ownership model. Opening one real session per VM would require a separate + transport/API decision and is not necessary for this deletion. +- **Create/dispose concurrency:** the current code registers a lease only after + VM creation succeeds. The event-loop hold keeps Node handles referenced but + is not itself a general lifecycle mutex. Do not claim Item 47 fixes a + concurrent `sidecar.dispose()` versus in-flight `AgentOs.create()` race unless + a dedicated test and a small explicit pending-lease mechanism are added. Do + not recreate the deleted session/VM state machine to solve that separate + concern. +- **Public API:** `AgentOsSidecarClient` is exported only from the repository- + internal source module and is not in the package export map + (`packages/core/package.json:11-41`) or root entrypoint. Remove it; do not + deprecate or preserve it as public compatibility surface. + +## Dependencies and nearby items + +- Stack Item 47 after Item 46 as requested by the one-item revision workflow; + there is no semantic dependency on Item 46's Rust presence work. +- Item 48 changes how a real VM admin materializes TypeScript host-backed overlay + state after initialization. Land Item 47 first or rebase its `createVmAdmin` + anchors carefully; do not pull Item 48's protocol/overlay changes into this + revision. +- Item 52 removes a separate legacy ACP notification path.

Refreshed on **2026-07-14** against +the active Item 80 working-copy code shape (`pzzlonpr`, parent `suwmustu`). This note does not modify +production code, tests, or the Item 48 tracker status.

The response tells TypeScript how to +construct caller-owned host state; it does **not** authorize TypeScript to turn +an omitted `readOnly` into an explicit override on a later request. + +The sidecar cannot own the `LayerStore`, `SnapshotLayerHandle`, or arbitrary +`VirtualFileSystem` object: those are live JavaScript objects reached through the +`js_bridge` callback. That backing state must remain in the TypeScript host. The +policy decision does not need to remain there. The correct split is: + +```text +TypeScript caller input (mode may be omitted) + -> MountDescriptor.readOnly remains omitted + -> sidecar resolves omitted readOnly to its default + -> response carries required resolved readOnly + -> TypeScript builds only the corresponding host callback backing store +``` + +Add a distinct wire type rather than returning an input `MountDescriptor` whose +`readOnly` field is still optional: + +```bare +type ResolvedMountDescriptor struct { + guestPath: str + readOnly: bool + plugin: MountPluginDescriptor +} +``` + +Both response fields should be named `resolvedOperatorMounts`. They contain the +stored operator mount list only: the explicit request list when supplied, or the +retained operator list when a configure request omits the whole field. Order and +cardinality are unchanged and `readOnly` defaults are materialized. Guest path +and plugin data remain the submitted operator descriptor data; this item does +not add path canonicalization. The list deliberately excludes package/provides +mounts owned and added by the sidecar. + +Priority: **P2**. Confidence: **medium**, matching the tracker. The diagnosis +and ownership boundary are high confidence, and native mount application already +uses the correct sidecar default. Implementation confidence is medium because +this is a lockstep protocol addition across native, browser, runtime-core, and +generated bindings, and TypeScript must preserve exact +descriptor-to-host-object correlation while Item 47 reshapes VM leasing. + +## Original issue + +The tracker entry is at `docs/thin-client-migration.md:94,181,273` in the +inspected working copy. + +`resolveCompatLocalMounts` in `packages/core/src/agent-os.ts` currently resolves +JavaScript-backed mounts before a sidecar VM exists. For an overlay it selects a +runtime policy default itself: + +```ts +const mode = mount.filesystem.mode ?? "ephemeral"; +const fs = + mode === "read-only" + ? mount.filesystem.store.createOverlayFilesystem({ + mode: "read-only", + lowers: mount.filesystem.lowers, + }) + : mount.filesystem.store.createOverlayFilesystem({ + upper: await mount.filesystem.store.createWritableLayer(), + lowers: mount.filesystem.lowers, + }); +``` + +That helper is invoked near the start of `AgentOs.create`, before +`createVmAdmin`, `ensureSharedSidecarNativeProcess`, and `initializeVm`. It +therefore allocates a writable layer and commits to ephemeral behavior before a +sidecar process has even been acquired, much less accepted the VM or resolved +the mount. + +At the same time, `collectSidecarMountPlan` correctly preserves the omission on +the wire: + +```ts +const readOnly = isOverlayMountConfig(mount) + ? mount.filesystem.mode === undefined + ? undefined + : mount.filesystem.mode === "read-only" + : mount.readOnly; +``` + +The result is two policy paths for the same mount: + +- the sidecar applies `MountDescriptor::effective_read_only()` from + `crates/sidecar-protocol/src/wire.rs:65-69`, where omission currently resolves + to writable (`false`); +- TypeScript independently interprets omission as ephemeral, allocates the + writable upper, and stores an omitted `LocalCompatMount.readOnly` value. + +Those happen to agree today. They can diverge as soon as the sidecar changes or +contextualizes its default. Dynamic mount reconfiguration in +`NativeSidecarKernelProxy.desiredSidecarMounts` correctly needs to resend the +caller's omission unchanged; the bug is that the already-created host overlay +was chosen without consuming the sidecar's applied result. The fix therefore +needs two values: the original descriptor for future requests and the resolved +descriptor for constructing host-only backing state. + +The local default appears a second time in +`packages/core/src/overlay-filesystem.ts`, and the `LayerStore` API permits an +omitted ephemeral mode on its writable branch. The existing test named +`defaults upper to in-memory filesystem` in +`packages/core/tests/overlay-backend.test.ts` explicitly preserves that default +by constructing `createOverlayBackend({ lower })` and expecting an implicit +writable in-memory upper. This is part of the tracker's “before” behavior. + +## Exact protocol edit + +### `crates/sidecar-protocol/protocol/agentos_sidecar_v1.bare` + +Add `ResolvedMountDescriptor` immediately after `MountDescriptor`. Add this +required field to both response types: + +```bare +type VmConfiguredResponse struct { + appliedMounts: u32 + resolvedOperatorMounts: list + projectedCommands: list + agents: list +} + +type VmInitializedResponse struct { + vmId: str + guestCwd: str + guestEnv: map + processRouteRetention: u64 + appliedMounts: u32 + resolvedOperatorMounts: list + projectedCommands: list + agents: list + hostCallbacks: list +} +``` + +Document on the field that it is a resolved applied view of the operator mount +list, not the full internal applied mount list. When +`ConfigureVmRequest.mounts` is omitted, it describes the VM's retained operator +mounts. Every returned `readOnly` is concrete; guest path and plugin are copied +without claiming that this response canonicalizes them. + +Run `pnpm --dir packages/build-tools build:protocol` and commit the regenerated +`packages/runtime-core/src/generated-protocol.ts`. Rust generated types are +built from the schema by `crates/sidecar-protocol/build.rs`; there is no +committed generated Rust file to hand-edit. Inspect the generated diff directly: +the declared `packages/build-tools` `check:generated` script currently targets +the missing root file `scripts/check-generated-artifacts.mjs`, so it is a known +repository gate defect rather than usable Item 48 validation. + +In `crates/sidecar-protocol/src/protocol.rs`, add the compatibility alias +`pub type ResolvedMountDescriptor = crate::wire::ResolvedMountDescriptor;` +beside the existing `MountDescriptor` alias. This lets shared response helpers +use the generated type through the same `protocol` surface as every other wire +descriptor; do not create a second handwritten struct. + +No backwards-compatibility shim or optional response field is needed. Protocol, +sidecars, and clients ship in lockstep. + +## What remains client-side + +Only state that the sidecar cannot serialize or access stays in TypeScript: + +- the caller's live `VirtualFileSystem`, `LayerStore`, snapshot handles, and + writable-layer handles; +- the `js_bridge` callback routing that lets a sidecar mount call those live + JavaScript objects; +- correlation between one forwarded `js_bridge` descriptor and its caller-owned + object, plus cleanup of host objects when startup or reconfiguration fails; and +- TypeScript package-manager default packages, which are the documented thin- + client exception and are unrelated to overlay policy. + +This does not leave a policy decision in the client. TypeScript validates the +sidecar's returned descriptor and constructs exactly the host backing it names. +The current `js_bridge` mount plugin does not invoke the host while the mount is +opened, so `initialize_vm` can safely commit the mount before TypeScript creates +the callback backing. Calls begin only after the returned VM is exposed through +`NativeSidecarKernelProxy`. + +Rust needs no equivalent host object. It should decode the lockstep response but +must not cache, reinterpret, or add a public overlay result solely for parity. + +## Exact sidecar edits + +### `crates/native-sidecar-core/src/frames.rs` + +Import `MountDescriptor` and `ResolvedMountDescriptor`. Add one shared resolver +so native and browser cannot materialize the default independently: + +```rust +fn resolved_operator_mounts(mounts: &[MountDescriptor]) -> Vec { + mounts + .iter() + .map(|mount| ResolvedMountDescriptor { + guest_path: mount.guest_path.clone(), + read_only: mount.effective_read_only(), + plugin: mount.plugin.clone(), + }) + .collect() +} +``` + +Change `vm_configured_response` at `frames.rs:178-191` to accept +`operator_mounts: &[MountDescriptor]` and fill `resolved_operator_mounts` with +that helper. Do not make callers calculate booleans themselves. + +Update `shared_response_helpers_preserve_payloads` at `frames.rs:648-662` to +pass `&[]`. Add a focused unit assertion with one `MountDescriptor` whose +`read_only` is `None` and one whose value is `Some(true)`; the response must +contain required `false` and `true` respectively while preserving order, +guest path, plugin ID, and plugin config. + +### `crates/native-sidecar/src/vm.rs` + +At the successful configure response at `vm.rs:655-659`, pass +`&operator_mounts` into `vm_configured_response`. This variable is the correct +source: + +- it is the explicit request list when supplied; +- it is the stored operator list when the request omits mounts; +- it excludes sidecar-owned package and `provides` mounts that are appended only + to `effective_mounts`; and +- it is the same list whose `effective_read_only()` values were used by mount + reconciliation through the mount helpers, which call + `MountDescriptor::effective_read_only()`. + +Do not resolve and store the descriptors back into +`VmConfiguration.operator_mounts`. Preserving caller omission in stored config +allows a future sidecar-default change to apply consistently on a later +reconfiguration. Resolve only the applied/result view. + +### `crates/native-sidecar-browser/src/wire_dispatch.rs` + +The browser dispatcher currently rejects any non-empty host mount list at +`wire_dispatch.rs:738-744`. Retain that capability boundary. After the rejection +check, bind `let operator_mounts = mounts.unwrap_or_default()` and pass +`&operator_mounts` to the shared `vm_configured_response` call at +`wire_dispatch.rs:808-812`. It is empty today, but returning the field keeps the +browser and native protocol behavior identical and avoids a second response +shape. + +### Atomic initialization responses + +Copy the already-resolved configure result into initialization: + +- add `resolved_operator_mounts: configured.resolved_operator_mounts` to + `crates/native-sidecar/src/service.rs:1601-1613`; +- make the same addition at + `crates/native-sidecar-browser/src/wire_dispatch.rs:1763-1776`. + +This is preferable to recomputing during initialization: `initialize_vm` is an +atomic composition of the create/configure/register operations, and its final +response should expose the exact configure result it committed. + +## Exact runtime-core edits + +### Generated/live descriptor mapping + +In `packages/runtime-core/src/descriptors.ts`, add: + +```ts +export interface LiveResolvedMountDescriptor { + guest_path: string; + read_only: boolean; + plugin: NativeMountPluginDescriptor; +} +``` + +Add `fromGeneratedResolvedMountDescriptor`, parsing optional plugin `JsonUtf8` +config with the existing JSON utility and preserving absence. Keep input +`LiveMountDescriptor.read_only` optional; only the response type is concrete. + +In `packages/runtime-core/src/response-payloads.ts`: + +- add `resolved_operator_mounts: LiveResolvedMountDescriptor[]` to the + `vm_initialized` and `vm_configured` variants at lines 147-165; +- map `payload.val.resolvedOperatorMounts` in both generated-response cases at + lines 367-405. + +### High-level sidecar process result + +In `packages/runtime-core/src/sidecar-process.ts`, add a concrete result type: + +```ts +export interface SidecarResolvedMountDescriptor + extends SidecarMountDescriptor { + readOnly: boolean; +} +``` + +Add `resolvedOperatorMounts: SidecarResolvedMountDescriptor[]` to +`InitializedVm` at lines 243-251 and `SidecarVmConfiguredResponse` at lines +360-364. Map the live snake-case descriptors in both `initializeVm` at lines +578-601 and `configureVm` at lines 675-685. A small +`fromWireResolvedMountDescriptor` helper should clone the plugin config just as +the existing request mapper does; do not reuse or mutate the caller's original +descriptor objects. + +The Rust SDK at `crates/client/src/agent_os.rs:309-354` may ignore the additional +initialization field. Rust has no JavaScript callback-backed `LayerStore` to +materialize, so inventing a Rust client cache or public result merely for parity +would add non-essential state. It still decodes the same lockstep response. + +## Exact TypeScript core edit + +### Preserve correlation in `collectSidecarMountPlan` + +Do not correlate the result back to live JavaScript objects by guest path alone: +paths may be normalized, and native descriptor deduplication already exists. +Extend the plan with an explicit response index recorded when each `js_bridge` +descriptor is pushed: + +```ts +interface CompatLocalMountPlan { + mount: PlainMountConfig | OverlayMountConfig; + sidecarMountIndex: number; + forwardedDescriptor: SidecarMountDescriptor; +} +``` + +Change `collectSidecarMountPlan` to return both `sidecarMounts` and +`compatLocalMounts`. For each non-native input, construct one `js_bridge` +descriptor, record `sidecarMounts.length`, and retain that exact descriptor in +the local plan before pushing it. Native mounts continue through their existing +dedupe path and do not get a local plan. + +Keep `OverlayMountConfig.filesystem.mode` and both corresponding Zod schema +fields optional. That omission is the public input that must reach the sidecar. + +### Resolve host backing state only after the response + +Change `resolveCompatLocalMounts` to accept the deferred plans and +`nativeVm.resolvedOperatorMounts`. For every plan: + +1. fetch the descriptor at `sidecarMountIndex`; +2. fail with a typed/descriptive startup error if it is absent, its normalized + guest path differs, or its plugin ID is not `js_bridge`; +3. use the required `descriptor.readOnly`, never `?? "ephemeral"` or the + original omitted value; +4. for a plain VFS, retain the caller's driver; no local policy wrapper is + needed because the sidecar/kernel enforces the resolved mount mode; +5. for an overlay, call `createOverlayFilesystem({ mode: "read-only", ... })` + when true; otherwise create the writable layer and call + `createOverlayFilesystem({ mode: "ephemeral", upper, ... })`; +6. store `forwardedDescriptor` as `LocalCompatMount.sidecarMount`. Later + `desiredSidecarMounts()` must resend the exact caller-authored descriptor, + including an omitted `readOnly`; it must not manufacture an explicit boolean + from the response. + +Delete the eager call near the start of `AgentOs.create` and materialize the +deferred plans immediately after the `initializeVm` result. Keep +`createdNativeVm = nativeVm` before validation or host materialization. If the +response is malformed or layer creation fails, the existing catch path can then +dispose the committed sidecar VM. This ordering also proves that a rejected +initialization cannot allocate a local writable layer. + +Construct `NativeSidecarKernelProxy` only after local resolution succeeds, with +the resolved local mounts and the original forwarded `sidecarMounts`. + +### Remove the remaining local overlay-mode defaults + +The host overlay engine should receive an explicit mode from its caller after +this change: + +- in `packages/core/src/overlay-filesystem.ts:17-49`, make + `OverlayBackendOptions.mode` required and replace + `const mode = options.mode ?? "ephemeral"` with `const mode = options.mode`; +- in `packages/core/src/layers.ts:53-63`, require `mode: "ephemeral"` on the + writable union branch; +- at `layers.ts:315-324`, pass `mode: "ephemeral"` explicitly into + `createOverlayBackend`; +- update direct core test construction to state `mode: "ephemeral"` explicitly. + +Do not remove the ability for explicit ephemeral mode to create a fresh +in-memory upper when the low-level caller omitted `upper`. The problem is the +mode default, not the copy-on-write implementation. + +## Before and after tests + +### Before evidence recorded by this research + +- [x] `packages/core/tests/overlay-backend.test.ts:173-180`, currently named + `defaults upper to in-memory filesystem`, proves the local backend selects + ephemeral behavior when mode is omitted. +- [x] `packages/core/tests/mount.test.ts:229-307` proves the current public omitted + overlay is writable and an explicit read-only overlay rejects writes. This is + the user-visible behavior that should remain under today's sidecar default. +- [x] Source assertion: `AgentOs.create` awaits `resolveCompatLocalMounts` before + it defines/runs `createVmAdmin`, which later calls + `ensureSharedSidecarNativeProcess` and `initializeVm`. The “before” checklist + should record this exact sequencing; a passing behavior test alone cannot + distinguish two identical defaults. + +The exact **parent-failing before test** should be added as +`packages/core/tests/overlay-sidecar-resolution.test.ts` before changing the +implementation: + +1. use `defaultSoftware: false` and a unique explicit `AgentOsSidecar`; +2. spy on `SidecarProcess.spawn` and return a minimal cast fake whose + authentication succeeds but whose `initializeVm` rejects with a sentinel + sidecar error; +3. pass an overlay mount with omitted `mode` and a `LayerStore` whose + `createWritableLayer` is spied; +4. assert `AgentOs.create(...)` rejects with the sentinel error; and +5. assert `createWritableLayer` was **not** called. + +That last assertion fails against the parent because +`resolveCompatLocalMounts(options.mounts)` allocates the upper before +`SidecarProcess.spawn`/`initializeVm`. It passes after materialization moves +behind the successful resolved response. The fake must implement +`closeSession`/`dispose`, the test must restore the static spawn spy, and the +unique sidecar must be disposed in `afterEach` so shared global state does not +leak. + +### After coverage to add or update + +- [ ] **Shared sidecar normalization —** extend + `crates/native-sidecar-core/src/frames.rs` unit coverage with omitted, + explicit false, and explicit true descriptors. Assert required concrete + results and descriptor ordering. +- [ ] **Native initialization —** add a case in + `crates/native-sidecar/tests/initialize_vm.rs` whose initialization request + contains a supported mount with `read_only: None`; assert + `resolved_operator_mounts[0].read_only == false`. Add one explicit true mount + assertion or cover that branch in the shared-core test. +- [ ] **Native configure retention —** extend a focused configure test in + `crates/native-sidecar/tests/service.rs` to assert both an explicit request + and a subsequent request with `mounts: None` return the same resolved + operator descriptors. This proves omission of the whole list retains state + while omission of an individual boolean is resolved by the sidecar. +- [ ] **Browser parity —** update + `browser_wire_dispatcher_configures_vm_permissions` and + `browser_wire_dispatcher_initializes_vm_atomically` in + `crates/native-sidecar-browser/tests/wire_dispatch.rs` to assert an empty + `resolved_operator_mounts` list. Keep the existing non-empty host-mount + rejection coverage. +- [ ] **Generated protocol parity —** add the new field to + `crates/native-sidecar/tests/generated_protocol.rs` and + `packages/core/tests/generated-protocol.test.ts` fixtures. Use at least one + descriptor in one fixture so required `readOnly` mapping is exercised, not + only an empty list. +- [ ] **runtime-core mapping —** update + `packages/runtime-core/tests/response-payloads.test.ts` and the in-memory + initialization response in + `packages/runtime-core/tests/sidecar-process.test.ts`. Assert the generated + camel-case value becomes live snake case and then high-level camel case with + a required boolean. Keep the existing request test proving omission is sent + as `null`/absent. +- [ ] **Typed fixture completeness —** add `resolved_operator_mounts: []` to the + live `vm_initialized` fixtures in + `packages/runtime-browser/tests/runtime/converged-executor-session.test.ts` + and any surviving BARE capture fixture in + `packages/core/tests/native-sidecar-process-permissions.test.ts` after Item + 45. A repository-wide `rg` for `vm_initialized`, `vm_configured`, + `VmInitializedResponse {`, and `VmConfiguredResponse {` must leave no + required-field construction stale. +- [ ] **TypeScript mount behavior —** in `packages/core/tests/mount.test.ts`, cover + three cases: omitted mode follows today's sidecar writable result, explicit + `ephemeral` remains writable/isolated, and explicit `read-only` returns + `EROFS`. Retain the existing lower-layer isolation assertion. +- [ ] **Resolved response controls host materialization —** in + `overlay-sidecar-resolution.test.ts`, have the fake sidecar return + `readOnly: true` for an input descriptor whose mode/read-only field was + omitted. Assert `createWritableLayer` is not called and + `createOverlayFilesystem` receives `{ mode: "read-only", ... }`. In a second + case return `readOnly: false`; assert one writable layer is allocated and + `createOverlayFilesystem` receives explicit `mode: "ephemeral"`. Also inspect + the captured initialization request and a later reconfiguration request to + prove both retain the omitted field. This is the decisive regression test: + the true-response case fails on the parent because the host overlay has + already been fixed to ephemeral before any response exists. +- [ ] **No low-level default —** replace the test at + `overlay-backend.test.ts:173-180` with an explicit-ephemeral test. Add + `mode: "ephemeral"` to the remaining direct constructors in that file and to + writable `createOverlayFilesystem` calls in `layers.test.ts` and + `leak-layer-store.test.ts`. +- [ ] **Rejected-sidecar allocation guard —** keep the parent-failing + `overlay-sidecar-resolution.test.ts` case above and make it pass. This + validates sequencing at runtime instead of relying only on a source + assertion. +- [ ] **Malformed-response rollback —** return a missing or mismatched + `resolvedOperatorMounts` entry from the same fake-sidecar test file. Assert a + descriptive startup failure, zero writable-layer allocations before response + validation, and one `disposeVm` call for the already-created VM. Add a + materialization-failure variant in the same harness to prove rollback after + allocation begins.

Missing/mismatched response data is a protocol/startup error, not a + reason to fall back to ephemeral. +- **Leaking a committed VM:** assign `createdNativeVm` before host overlay + materialization so the existing startup rollback reaches `disposeVm`. +- **Leaking a host layer on partial local resolution:** if multiple local mounts + are materialized and a later one fails, dispose/release any already-created + host overlay resources if the layer abstraction gains such an API. Today the + `LayerStore` has no per-overlay release operation, so do not invent a silent + cleanup; preserve the original error and log any available cleanup failure. +- **Dynamic reconfiguration regression:** store the original forwarded + descriptor on `LocalCompatMount` and resend it unchanged. Do not store the + resolved boolean in the request descriptor: doing so would turn the + sidecar's observation into a client-authored override and violate the thin- + client omission invariant. +- **Browser overreach:** do not add browser host-mount support in this item. It + returns an empty resolved list because it accepts only absent/empty mounts. +- **Accidental public narrowing:** only low-level host-overlay construction gets + a required mode.

This note does not modify production +code, tests, or the Item 49 tracker status. + +## Recommendation + +Remove six unused production dependencies from `@rivet-dev/agentos-core`: + +- `@aws-sdk/client-s3`; +- `better-sqlite3`; +- `googleapis`; +- `isolated-vm`; +- `long-timeout`; and +- `minimatch`. + +Delete the orphaned `long-timeout` ambient declaration and remove the one example +TypeScript configuration that explicitly includes it. Remove `better-sqlite3` +from the workspace build-script allowlist, then regenerate the root workspace +lockfile. + +Delete `packages/core/pnpm-lock.yaml` rather than regenerating it. Core is a +member of the root pnpm workspace, every documented Core command resolves +through that workspace, and the package publishes only `dist`. The nested lock +is therefore neither authoritative nor shipped. It is already stale: its +importer omits current workspace dependencies while retaining links into the old +`secure-exec` tree. Keeping a second hand-maintained lock would preserve exactly +the sort of legacy package state this item is removing. + +Do not move any of these packages to the sidecar. There is no client behavior to +preserve: none is imported by Core. Runtime functionality already uses sidecar +RPCs or native Node facilities. This item is deletion, not migration. + +Priority: **P2**. Confidence: **high**. The source/import result is unambiguous. +The only potentially noisy part is the generated root lock diff because the +direct `better-sqlite3` dependency currently satisfies RivetKit's optional +Drizzle peer across the workspace. + +## Original issue + +The Item 49 tracker says Core declares unused heavy production dependencies and +an orphaned `long-timeout` declaration. This violates the thin-client boundary +in two ways: + +1. the published client advertises and installs implementation stacks that it + never calls; and +2. stale dependency metadata suggests that S3, Google APIs, SQLite, isolate + hosting, glob policy, and long-duration scheduling are client concerns. + +The actual client does none of those things through these packages. Removing +them reduces install/build surface without changing the wire protocol or moving +unneeded behavior into the sidecar. + +The file/symbol/lock anchors below were re-verified in the shared working copy +at revision `930e5829fb25` (`fix(sidecar): remove implicit host path +execution`). Re-run the supplied `rg` and `pnpm why` inventory immediately +before implementation because the root lock and line numbers can move as +earlier stacked items land. + +## Dependency audit and exact verdicts + +`packages/core/package.json:50-64` declares fourteen production dependencies. +An exact-name scan of `packages/core/src`, `packages/core/tests`, and +`packages/core/scripts` finds no import or dynamic load of five removal +candidates.

It does not depend on the +`long-timeout` package. Do not remove or sidecar-ize this host alarm as part of +Item 49; only delete the unused declaration and package. + +Core's `tsconfig.json:11` includes all of `src/**/*`, so the ambient declaration +is currently compiled even though it is unused. In addition, +`packages/secure-exec-example-ai-agent-type-check/tsconfig.json:16` explicitly +reaches into Core to include the declaration. That cross-package include is the +only external source reference and must be removed with the file. + +## Exact edits + +### `packages/core/package.json` + +Delete only the six dependency entries listed above.

Evidence that it is a stale parallel source of truth: + +- `packages/core` is explicitly listed in the root `pnpm-workspace.yaml`; +- the root pins `pnpm@10.13.1` and owns `pnpm-lock.yaml`; +- every repository command found for Core uses `pnpm --dir packages/core ...` + from within that workspace, with no `--ignore-workspace` path; +- the package publishes only `dist`, so consumers never receive the lock; +- its importer omits current production workspace dependencies; and +- it still contains `link:../../../secure-exec/...` entries. + +Do not spend review effort mechanically pruning a 200 KB lockfile that pnpm does +not use in this repository. + +### Root `pnpm-lock.yaml` + +After the manifest and workspace-policy edits, run the pinned workspace pnpm to +regenerate the root lock: + +```sh +pnpm install --lockfile-only +``` + +Review the generated diff rather than hand-editing it. It must remove the six +entries from the `packages/core` importer at current lines 2426-2455 and prune +dependency subtrees that no other importer reaches. The following direct +changes are guaranteed by the manifest edit: + +- delete Core's importer entries for all six packages; +- delete the root package and snapshot entries for `@aws-sdk/client-s3`, + `googleapis`, `isolated-vm`, and `long-timeout` when the regenerated graph + confirms no other importer/edge; +- delete `better-sqlite3@12.8.0`, prune any of its native dependency subtree + that is now unreachable, and rewrite the Drizzle/RivetKit snapshots so they + no longer resolve that optional peer; +- retain `minimatch@10.2.5`, because the `packages/posix` importer at current + lines 2651-2665 still selects it, while removing only Core's edge; +- prune shared transitive packages only when no remaining importer or snapshot + reaches them. Do not remove AWS/Google/native-build utilities by name without + letting pnpm prove they are unreachable. + +A large peer-suffix diff is expected. The current direct `better-sqlite3` +dependency causes workspace RivetKit snapshots to resolve as +`rivetkit@...(...)(better-sqlite3@12.8.0)(...)`, and Drizzle's snapshot currently +has `better-sqlite3` as an optional dependency. Once no workspace manifest +provides that optional peer, pnpm will rewrite those contexts without the +SQLite suffix. That churn is caused by Item 49 and should not be reverted merely +to keep the lock diff small. + +Conversely, do not assert that every `minimatch` string vanishes from the root +lock. `packages/posix/package.json:31` legitimately declares its own +`minimatch` dev dependency. Validate Core's importer and manifest, not global +string absence. + +## Before and after validation + +This item has no runtime behavior to preserve, but the thin-client package +boundary is testable. Add a focused manifest/source regression test before the +deletion so there is executable evidence that fails on the Item 49 parent and +passes after it. Compilation, consumer typechecking, a packed-package smoke +test, and frozen-lock verification then prove that deleting the declarations +does not remove real behavior. + +### Before test that fails on the current parent + +Add `packages/core/tests/thin-client-dependencies.test.ts` before changing the +manifest.

Repository-wide usage shows that the +legacy aliases and discriminator are used only by their own tests, while all +registry packages and checked examples already use `{ packagePath }`. The +remaining raw-string uses are local test fixtures and three actor fixtures that +can be converted mechanically. + +## Original issue and before evidence + +The tracker entry is at `docs/thin-client-migration.md:96,183,275`. + +### The deprecated public type is literally a string + +`packages/core/src/agentos-package.ts:15-35` imports the migration-era manifest +`PackageRef = string`, re-exports it, aliases it as a deprecated +`PackageDescriptor`, and provides a public discriminator: + +```ts +export type PackageRef = ManifestPackageRef; +export type SoftwarePackageRef = { packagePath: string }; +/** @deprecated Package software is now represented by its package directory. */ +export type PackageDescriptor = PackageRef; + +export function isPackageDescriptor( + value: unknown, +): value is PackageDescriptor { + return typeof value === "string"; +} +``` + +The aliases are re-exported from `packages/core/src/types.ts:90-95`, and the +guard is re-exported from `packages/core/src/index.ts:33-37`. No production code +calls the guard. Its only consumers are: + +- `packages/core/tests/agentos-package.test.ts`, which asserts strings are the + legacy descriptor; and +- `packages/core/tests/public-api-exports.test.ts:17,76`, which asserts the + guard remains public. + +The manifest package's own unrelated `PackageDescriptor` interface describes +package authoring metadata, and the sidecar protocol's `PackageDescriptor` +union describes path/inline transport. Do not delete either merely because the +names overlap. + +### Runtime paths still accept the removed shape + +The core source type `SoftwareInput` at `packages/core/src/packages.ts:10-11` +already contains only `SoftwarePackageRef` objects and their one-level arrays. +Despite that, three runtime surfaces retain string compatibility: + +- `packages/core/src/options-schema.ts:268-275` unions `z.string()` with the + object schema; +- `packages/core/src/agent-os.ts:671-685` calls a raw string “shorthand” and + normalizes it to a path; +- `AgentOs.linkSoftware` at `agent-os.ts:2135-2138` explicitly accepts + `PackageRef | SoftwarePackageRef`. + +The actor copies the same branch at +`packages/agentos/src/actor.ts:103-116`, and its native options schema consumes +the shared core software schema. This is duplicated client compatibility, not a +sidecar requirement. + +### The public API test is transpiled but not typechecked + +`packages/core/tests/public-api-exports.test.ts:75-77` currently says: + +```ts +expect(defineSoftware("/opt/pkg")).toBe("/opt/pkg"); +expect(isPackageDescriptor).toBeTypeOf("function"); +``` + +`defineSoftware` is correctly declared as +`T extends SoftwarePackageRef` at `packages/core/src/packages.ts:20-22`, so the +string call is already unsupported by the source type. Vitest transpiles the +test without checking it, and `packages/core/tsconfig.json` includes only +`src/**/*`. Consequently the runtime identity function returns the invalid +string and the test passes. + +The current baseline demonstrates the gap exactly. The combined runtime +characterization passes all 19 tests across the public export, legacy guard, and +software-schema files: + +```console +$ pnpm --dir packages/core exec vitest run \ + tests/public-api-exports.test.ts \ + tests/agentos-package.test.ts \ + tests/options-schema.test.ts +Test Files 3 passed (3) +Tests 19 passed (19) + +$ pnpm exec tsc --noEmit --target esnext --module NodeNext \ + --moduleResolution NodeNext --strict --skipLibCheck --types node \ + packages/core/tests/public-api-exports.test.ts +public-api-exports.test.ts(76,25): error TS2345: Argument of type 'string' is +not assignable to parameter of type 'SoftwarePackageRef'. +``` + +That focused compiler invocation also reports three existing `TS18048` +diagnostics where the test dereferences optional mount plugin config at lines +110, 111, and 117. Reshape those assertions as part of enabling the gate; do not +weaken compiler settings. + +The actor's configuration-only characterization is also independently runnable +without booting RivetKit or resolving a native sidecar binary: + +```console +$ pnpm --dir packages/agentos exec vitest run tests/actor.test.ts \ + -t 'buildConfigJson|auto-injects|does not duplicate|explicit /root|rejects removed|rejects an unrecognized' +Test Files 1 passed (1) +Tests 7 passed | 8 skipped (15) +``` + +Running the whole actor file in this checkout reaches four unrelated integration +tests and fails because the optional published platform sidecar package is not +installed. Use the filtered command for this item's fast before/after gate; use +the full file only with `AGENTOS_PLUGIN_BIN` and `AGENTOS_SIDECAR_BIN` pointing +at built checkout binaries. + +### Documentation and checked examples + +All checked `defineSoftware` consumers already use the supported object form: + +- `examples/custom/pi-cli.ts`; +- `examples/software/quickstart-{node,wasm,agent}/*.ts`; and +- `website/src/content/docs/docs/{agents/custom,custom-software/definition}.mdx`. + +They need no Item 50 behavior edit and serve as positive compile examples. Two +known documentation surfaces are stale for broader reasons: + +- `packages/agentos-toolchain/README.md` still shows `{ name, dir }`; and +- generated `website/public/docs/**` still contains old `{ packageDir }` output. + +Item 51 already owns those source/generated documentation corrections. Do not +hand-edit generated website output or expand Item 50 into package-format prose. +Within Item 50, update the legacy `software: []` comments in touched fixture +files, plus `packages/core/tests/pty-line-discipline.test.ts:121-124`, to show +`{ packagePath }` even though that PTY test already uses the correct object. + +`packages/core/tests/options-schema.test.ts:66-85` is the separate runtime +“before” test: it currently lists a raw string among accepted serializable +software refs. `packages/core/tests/agentos-package.test.ts:9-15` is the legacy +export “before” test. + +## Exact core production edits + +### `packages/core/src/agentos-package.ts` + +Remove `PackageRef as ManifestPackageRef` from the manifest import. Delete: + +- `PackageRef`; +- deprecated `PackageDescriptor`; and +- `isPackageDescriptor`. + +Keep `AgentBlock`, `SoftwarePackageRef`, `OPT_AGENTOS_ROOT`, and +`OPT_AGENTOS_BIN`. The resulting client descriptor surface is only: + +```ts +export type SoftwarePackageRef = { packagePath: string }; +``` + +Do not rename this to the protocol's `PackageDescriptor`; keeping the client +input and wire transport concepts distinct avoids restoring the old ambiguity. + +### `packages/core/src/index.ts` and `packages/core/src/types.ts` + +In `index.ts:33-37`, remove `isPackageDescriptor` and keep only the two path +constants in that value export block. + +In `types.ts:90-95`, remove `PackageDescriptor` and `PackageRef`; keep +`AgentBlock` and `SoftwarePackageRef`. + +### `packages/core/src/options-schema.ts` + +Replace the union at lines 268-271: + +```ts +const softwarePackageRefSchema = z.object({ packagePath: z.string() }); +``` + +Keep `softwareInputSchema` as the union of one object and an array of those +objects. Meta-packages remain supported. Zod may accept/strip future object +fields as it does today; the client needs only `packagePath` and must not inspect +package semantics. + +### `packages/core/src/agent-os.ts` + +Remove `PackageRef` from the import at lines 107-108. + +Delete the string branch from `normalizePackageRef` at lines 671-685. Keep the +structural runtime check because untyped JavaScript can still call the SDK: + +```ts +function normalizePackageRef(value: unknown): NormalizedPackageRef { + const record = toRecord(value); + if (typeof record.packagePath === "string") { + return { path: record.packagePath }; + } + throw new TypeError( + "Invalid software package reference: expected { packagePath: string }", + ); +} +``` + +Do not read the path or inspect an `.aospkg`; `normalizePackageRef` remains only +structural serialization. + +Narrow `linkSoftware` at lines 2135-2138 to: + +```ts +async linkSoftware(descriptor: SoftwarePackageRef): Promise +``` + +It should still call the same normalizer and forward `{ path: ref.path }` to +`linkPackage`. This ensures an untyped string also receives the same explicit +runtime error rather than becoming `{ path: undefined }`. + +No change is needed in `packages/core/src/packages.ts`: `SoftwareEntry`, +`SoftwareInput`, and `defineSoftware` already describe the correct object shape. +Update its package-dir wording only if Item 51 has not already corrected it; do +not broaden Item 50 into package-format documentation cleanup. + +## Exact actor edit + +In `packages/agentos/src/actor.ts:103-116`, delete the raw-string branch and +change the error to: + +```text +Invalid software package reference: expected { packagePath: string } +``` + +Retain the object check, exact-path deduplication, meta-package flattening, and +conversion to `{ packagePath: ref.path }` for the Rust actor plugin. No Rust +change is needed: `crates/agentos-actor-plugin/src/config.rs` already receives +the canonical `packagePath` object form. + +This actor edit is required even though the shared Zod schema rejects strings. +It removes the copied compatibility behavior and keeps the serializer total if +it is ever called with unchecked input. + +## Make the public API test a real type gate + +### Add `packages/core/tests/tsconfig.public-api.json` + +Use a focused test config rather than adding the entire runtime/e2e suite to the +library declaration build: + +```json +{ + "extends": "../tsconfig.json", + "compilerOptions": { + "noEmit": true, + "rootDir": ".." + }, + "include": ["./public-api-exports.test.ts"] +} +``` + +Overriding `rootDir` is necessary because the inherited core config points at +`src/`. Do not disable `strict`, add `any`, or use a transpile-only checker. + +### `packages/core/package.json` + +Append the focused gate to the existing scoped script: + +```json +"check-types": "pnpm run build:protocols && tsc --noEmit && tsc -p tests/tsconfig.public-api.json" +``` + +The root remains Turbo orchestration only, as required by the repository +working agreement. + +### `packages/core/tests/public-api-exports.test.ts` + +Make these changes: + +1. Import the root module as a namespace for a runtime absence assertion. +2. Delete the named `isPackageDescriptor` import and expectation. +3. Replace the string identity assertion with an object assertion: + + ```ts + const software = defineSoftware({ packagePath: "/opt/pkg" }); + expect(software).toEqual({ packagePath: "/opt/pkg" }); + ``` + +4. Add a compile-only negative case in an unreachable branch: + + ```ts + if (false) { + // @ts-expect-error raw string package descriptors are not supported + defineSoftware("/opt/pkg"); + } + ``` + + The new test tsconfig makes the directive fail as unused if string support is + accidentally restored. +5. Assert `"isPackageDescriptor" in rootApi` is false. Add compile-time absence + assertions for `PackageDescriptor` and `PackageRef`, for example with + `@ts-expect-error` type queries against `import("../src/index.js")`. This + proves both value and type legacy exports are gone. +6. Replace direct optional `mount.plugin.config.hostPath/readOnly` property + access at lines 109-116 with `toMatchObject`/whole-object assertions so the + focused strict compile passes without non-null assertions. + +Keep `SoftwarePackageRef` exported and add it to the public type smoke section +if it is not already covered. The desired contract is removal of the string +aliases, not removal of the canonical descriptor type. + +## Runtime fixture migration + +Delete `packages/core/tests/agentos-package.test.ts`; after the guard is removed +it has no remaining behavior to test. The root API test owns the absence check. + +Update every local string package fixture to wrap the path without changing the +package contents or sidecar assertions: + +```ts +software: [{ packagePath: pkgDir }] +await vm.linkSoftware({ packagePath: pkgDir }) +``` + +The current raw-string call sites are: + +- `packages/core/tests/agentos-projection-isolation.test.ts:45`; +- `packages/core/tests/agentos-package-agent-vm.test.ts:104`; +- `packages/core/tests/agentos-package-vm.test.ts:47`; +- `packages/core/tests/agentos-package-real-agent.e2e.test.ts:75`; +- `packages/core/tests/list-agents.test.ts:45` (wrap both joined paths); +- `packages/core/tests/fs-native-parity.test.ts:188`; +- `packages/core/tests/pty-protocol.test.ts:183`; and +- all three calls in + `packages/core/tests/agentos-package-link-vm.test.ts:65,94,119`. + +The unchecked package-local snapshot driver +`packages/core/vim-snap.mjs:19-25,69-72` also returns a raw package-directory +string and passes it as a software leaf. Wrap its result at the call site (or +change `materializeVimPackage` to return `{ packagePath }`) so removing the +runtime compatibility branch does not leave a broken repository script. This +file is not part of the TypeScript compiler gate, which is why a source-only +audit is required in addition to `check-types`. + +`packages/core/tests/pty-line-discipline.test.ts:706` already wraps its returned +string and needs no edit. Registry package imports such as `common`, `pi`, and +`coreutils` already default-export `{ packagePath }` and also need no edit. + +In `packages/agentos/tests/actor.test.ts`, replace all three raw-string fixtures +at lines 456, 477, and 491 with `{ packagePath: "..." }`, preserving the expected +serialized objects. Add a rejected raw-string case beside the existing malformed +and removed-field cases at lines 529-550. + +In `packages/core/tests/options-schema.test.ts`: + +- move a valid-looking raw string into the rejected table at lines 57-64; +- remove the string from the accepted list at lines 74-83; +- retain one direct object, one extensible object, and one object meta-package + array. + +Add a `linkSoftware` runtime rejection test using a deliberately untyped value +(`as never` is acceptable only at this negative boundary).

Active agent instructions describe a broken, deleted architecture + +`crates/CLAUDE.md:8` first describes V8 correctly, then says the execution +engine is “CURRENTLY BROKEN,” spawns host Node, and must be recovered from an +external secure-exec checkout. That is false: the live path uses the shared V8 +runtime. The same file contains many references to deleted +`crates/sidecar/...` and `crates/sidecar-browser/...` paths, and line 138 says +`permissions: None` means default-deny in sidecar tests. + +`crates/execution/CLAUDE.md:17-74` combines a correct current-state sentence +with a historical recovery checklist and a “current reality” table that still +says builtins fall through to real host Node. The table contradicts both the +preceding current-state paragraph and the current V8 bridge/conformance suites. +The remainder of the file repeatedly points at deleted `crates/sidecar` and +`packages/secure-exec-core` paths. + +`packages/core/CLAUDE.md` has the same contradictions: + +- line 5 says Node execution is currently broken; +- line 9 says the SDK wraps the kernel and proxies it directly; +- line 39 points at the deleted + `crates/sidecar/protocol/agentos_native_sidecar_v1.bare`; +- line 103 points tests at `crates/sidecar/tests`; and +- line 201 attributes AgentOS queue tracking and logging to secure-exec and + documents an unimplemented `SECURE_EXEC_LOG` knob. + +The root `CLAUDE.md:47-69` is already correct and should not be rewritten. It +clearly says clients are thin transports, omissions stay omitted, the sole +TypeScript exception is package-manager default selection, package resolution +is sidecar-owned, and `agentos-package.json` is pack-time input. Item 51 should +make the verifier require those claims so deletion cannot make stale guidance +look acceptable. + +### 2. Published docs say the sidecar is in-process + +The following active text contradicts the actual child/shared-sidecar process: + +- `README.md:16,24,135` — “runs inside your process,” “in-process operating + system kernel,” and “nothing executes on the host”; +- `examples/core/README.md:10,16` — “no client/server split” and “boots a VM + in-process”; +- `website/src/content/docs/docs/core.mdx:34` — the same claim immediately + before lines 38-46 correctly describe the shared sidecar process; and +- `website/src/content/docs/docs/versus-sandbox.mdx:7,15` plus + `website/public/docs/docs/versus-sandbox.md:5,13` — “runs inside your + process.” + +The correct distinction is not “process versus VM.” The trusted client spawns +or reuses a local sidecar process; each VM is lightweight sidecar-owned kernel +state plus its executors, rather than a full container or one host process per +VM. Guest code remains isolated and resource access is mediated even though the +trusted sidecar itself necessarily runs on the host. + +### 3. Package docs teach the transition directory as the runtime format + +The largest stale surface is +`website/src/content/docs/docs/architecture/packages-and-command-resolution.mdx` +and its checked public Markdown copy. Current lines 3, 63-113 say: + +- a package is a directory/plain npm dependency; +- `package.json` and `agentos-package.json` are projected into the guest; +- the sidecar reads the JSON on mount; +- commands are discovered from runtime `package.json`; +- clients forward a package directory; and +- package roots omit the required `pkgs` component. + +The page's linking section at lines 115-168 also describes package links as +writable-layer filesystem entries with snapshot persistence. In the live +implementation they are sidecar-managed package leaf mounts. A live +`LinkPackage` updates `VmConfiguration.mounts`, command maps, driver +registration, and projected agent launch state; `ExportSnapshot` exports a +filesystem layer, not external package descriptors. Therefore the docs must +promise live-VM duration only, not persistence of a dynamic package reference +through a layer snapshot/recreated VM. + +Other active package guidance repeats the old model: + +- `packages/agentos-toolchain/README.md:10-25,30-55,74-76` says secure-exec owns + packaging, the output is a directory with no JSON, and consumers use a + directory descriptor.

This +note does not change production code, tests, or Item 52's tracker status. + +Priority: **P2**. Implementation confidence: **high** (raise the tracker's +current medium rating when Item 52 is implemented).

Keep only the generated `AcpPermissionCallback` route that +forwards raw adapter params to the host handler and returns the handler's reply +to the sidecar. + +Do **not** add another sidecar state machine. The native sidecar already: + +1. recognizes the adapter's `session/request_permission` JSON-RPC request; +2. sends a typed `AcpPermissionCallback` to the client; +3. owns the decision timeout and missing-answer default; and +4. maps the abstract host reply to an option ID the active adapter offered. + +The implementation is therefore a client deletion plus conformance coverage, +not a production sidecar migration. + +## Original legacy issue + +TypeScript hard-codes both a pre-ACP method alias and the current ACP method at +`packages/core/src/agent-os.ts:628-629`: + +```ts +const LEGACY_PERMISSION_METHOD = "request/permission"; +const ACP_PERMISSION_METHOD = "session/request_permission"; +``` + +`AgentOs._recordSessionNotification` at current lines 2183-2214 treats either +method as a host permission request: + +```ts +if ( + notification.method === LEGACY_PERMISSION_METHOD || + notification.method === ACP_PERMISSION_METHOD +) { + const params = toRecord(notification.params); + const permissionId = params.permissionId; + if ( + typeof permissionId === "string" || + typeof permissionId === "number" + ) { + const request: PermissionRequest = { + permissionId: String(permissionId), + description: + typeof params.description === "string" + ? params.description + : undefined, + params, + }; + for (const handler of session.permissionHandlers) { + handler(request); + } + } +} +``` + +That branch invokes the host handler without inserting the permission ID into +`session.pendingPermissionReplies`. `AgentOs.respondPermission` at current +lines 2968-2991 accepts only a pending typed callback and otherwise rejects: + +```text +Permission request is not pending: +``` + +The result is a false API promise: the client tells the host that a permission +request exists, but the host cannot answer it. A normal handler that calls +`void vm.respondPermission(...)` can produce an unhandled rejected promise.

These events contain adapter **notifications**, principally `session/update`. | Keep the caller and session-update delivery. It must not reinterpret a notification as a request. | +| `crates/agentos-sidecar-core/src/engine.rs:806`, `AcpCore::encode_session_notification` | The sole current `AcpSessionEvent` producer serializes values previously classified as `Notification`, plus sidecar-generated `session/update` state notifications. | Keep unchanged. It cannot produce a valid permission request because requests are consumed before event encoding. | +| `crates/agentos-sidecar-core/src/engine.rs:4525`, `answer_inbound_request` | Every resumable engine path sends `id + method` frames directly to `AcpHost::handle_inbound_request`; blocking JSON-RPC does the same in `crates/agentos-sidecar-core/src/json_rpc.rs:93-110`. | Keep unchanged. This is the authoritative request/response boundary. | +| `crates/agentos-sidecar/src/acp_extension.rs:1970`, `build_inbound_response` | Native `session/request_permission` requests become a typed host callback, then an adapter JSON-RPC response with the original ID. | Keep unchanged except for the conformance assertions described below.

Therefore the +TypeScript permission-notification branch has no current production producer. + +### Native sidecar already owns modern permission behavior + +The native host adapter's exact path is: + +1. `NativeCoreHost::handle_inbound_request` in + `crates/agentos-sidecar/src/acp_extension.rs:194-203` sends the complete + request to the native async broker. +2. `build_inbound_response` at lines 1970-2072 matches + `session/request_permission` at lines 1983-2055 before filesystem, terminal, + and generic host-extension methods. +3. It serializes the adapter's raw `params` into `AcpPermissionCallback`, sets a + 125-second client cleanup deadline, invokes the callback under the + sidecar-owned 120-second decision deadline, and writes the response using the + original adapter request ID. +4. `permission_callback_reply_from_result` at lines 2883-2897 applies the + sidecar default on timeout; other callback failures propagate. +5. `permission_result` and `resolve_permission_option_id` at lines 2861-2925 map + `once`, `always`, or `reject` to an option ID actually offered in this + request. That preserves adapters such as OpenCode whose option ID is `once` + rather than `allow_once`. + +This is adapter-specific ownership in practice: the native adapter supports the +callback because it has a client callback bridge. The browser adapter has no +such bridge and uses the default `AcpHost::handle_inbound_request` response from +`crates/agentos-sidecar-core/src/host.rs:81-90`; its own comment at +`crates/agentos-sidecar-browser/src/acp_host.rs:195-198` explicitly says it does +not advertise agent-to-client callback tooling. + +If a named agent adapter later needs a nonstandard permission method, add a +tested compatibility branch in the native sidecar's inbound-request handling. +If the alias is adapter-specific, first retain enough sidecar session metadata +to gate it to that adapter; the current `NativeCoreProcess` records ownership +and session ID but not adapter identity, so adding an unconditional alias to +`build_inbound_response` would incorrectly advertise it to every adapter. Do +not copy method strings into TypeScript or Rust. + +### Rust already has the desired thin-client boundary + +Rust's `handle_acp_ext_callback` at +`crates/client/src/agent_os.rs:1279-1330` decodes only the generated +`AcpPermissionCallback`, deserializes its raw params, routes the host closure by +VM/session ownership, and returns `AcpPermissionCallbackResponse`.

Do not partially rewrite it in Item + 52; replace and delete that harness as one separately tracked cleanup. + +### Item 81 owns the adjacent legacy test harness + +`crates/native-sidecar/tests/acp_legacy/{compat.rs,client.rs}` still contains a +complete duplicate of the old client permission normalization: both method +constants, `PendingPermissionRequests`, `_acpMethod` injection, synthetic +`request/permission` notifications, response option normalization, and its own +bounded pending-reply state. It is pulled into `acp_integration.rs`, +`acp_session.rs`, and `service.rs` only as test scaffolding; it is not linked +into a published client or sidecar. + +That code is the separately tracked **Item 81**, now the active stacked change +at the time of this revalidation. Item 81 maps any narrow useful assertions to +the production shared/native ACP suites and deletes the whole harness. Item 52 +must neither edit those files nor resurrect them if they are gone by the time +implementation starts. Deleting only the harness's permission branch would +leave a half-migrated fake client; moving any of its state into production would +recreate the architecture this work is removing. + +## Exact test edits + +### 1. Before characterization and lasting TypeScript regression + +Add a table-driven test in +`packages/core/tests/session-config-routing.test.ts` covering both +`request/permission` and `session/request_permission`. + +Before deleting production code, its assertions must be: + +```ts +expect(permissionHandler).toHaveBeenCalledOnce(); +expect(session.pendingPermissionReplies.size).toBe(0); +await expect( + agent.respondPermission("session-1", "legacy-permission", "once"), +).rejects.toThrow("Permission request is not pending: legacy-permission"); +``` + +This is the exact before proof: the legacy branch raises a permission callback +that cannot be answered. Run both table cases and record the passing command in +the tracker before changing `agent-os.ts`. + +After deleting the branch, retain the test and change only the first assertion: + +```ts +expect(permissionHandler).not.toHaveBeenCalled(); +``` + +The final test can use this exact private-backdoor shape (before the production +deletion, change only `not.toHaveBeenCalled()` to `toHaveBeenCalledOnce()`): + +```ts +it.each(["request/permission", "session/request_permission"])( + "does not interpret the %s session notification as a permission callback", + async (method) => { + const agent = Object.create(AgentOs.prototype) as AgentOs; + const permissionHandler = vi.fn(); + const session = { + eventHandlers: new Set(), + permissionHandlers: new Set([permissionHandler]), + pendingPermissionReplies: new Map(), + }; + const backdoor = agent as unknown as { + _sessions: Map; + _recordSessionNotification: ( + session: typeof session, + notification: { + jsonrpc: "2.0"; + method: string; + params: Record; + }, + ) => void; + }; + backdoor._sessions = new Map([["session-1", session]]); + + backdoor._recordSessionNotification(session, { + jsonrpc: "2.0", + method, + params: { + permissionId: "legacy-permission", + description: "dead notification route", + }, + }); + + expect(permissionHandler).not.toHaveBeenCalled(); + expect(session.pendingPermissionReplies.size).toBe(0); + await expect( + agent.respondPermission("session-1", "legacy-permission", "once"), + ).rejects.toThrow( + "Permission request is not pending: legacy-permission", + ); + }, +); +``` + +Use the existing private-test backdoor style in that file; do not expose a new +public production method for the test. + +### 2.

Item 54 must therefore +target Item 46's final representation, preserve its omission semantics, and +replace the lossy conversion in its own dedicated revision. + +Neither live defect should be moved into the sidecar: + +- a TypeScript listener is executable host state that the sidecar cannot invoke + or inspect; and +- the Rust client must serialize its typed caller input before any protocol + request can exist. + +The sidecar already owns MCP defaults, JSON validation, adapter startup, and ACP +forwarding.

At lines 378-387 it currently +does this: + +```ts +for (const listener of this.eventListeners) { + if (!ownershipMatchesSelector(listener.ownership, event.ownership)) { + continue; + } + try { + listener.handler(event); + } catch { + // Event listeners are best-effort observers and must not break framing. + } +} +``` + +The isolation is correct; the empty catch is not. Production listeners enter +through: + +- `packages/runtime-core/src/native-client.ts:137-142`; +- `packages/runtime-core/src/sidecar-process.ts:423-428`; and +- AgentOS's top-level router at `packages/core/src/agent-os.ts:1337-1344` + (`this._sidecarClient.onEvent(...)`). + +An exception from any direct runtime-core consumer or the AgentOS router is +therefore invisible today. + +Do **not** rethrow. `dispatchEvent` runs in inbound frame dispatch, so rethrowing +an arbitrary host callback error could break framing, skip sibling listeners, +strand a waiter, or prevent bounded-buffer delivery. The repository rule allows +the failure to be clearly logged at its failure site, and Item 54 explicitly +allows a structured warning. + +### Audited paths that do not belong to Item 54 + +| Path | Current behavior | Disposition | +|---|---|---| +| `packages/core/src/agent-os.ts:2252-2260` session subscribers | isolates and warns | already compliant | +| `packages/core/src/agent-os.ts:2331-2344` warning callback | isolates and warns | already compliant | +| `packages/core/src/agent-os.ts:2358-2368` ACP stderr callback | isolates and warns | already compliant | +| `packages/core/src/agent-os.ts:2385-2398` ACP exit callback | isolates and warns | already compliant | +| `packages/core/src/cron/cron-manager.ts:300-305` cron listeners | isolates and warns | already compliant | +| `packages/core/src/sidecar/rpc-client.ts:825-830,873-874` stdout/stderr fan-out | listener throws can abort sibling delivery | Item 69, not a swallowed exception | +| `packages/core/src/agent-os.ts:2238-2239` legacy permission handlers | uncaught legacy route | Item 52 removes the legacy interpretation | +| `packages/core/src/agent-os.ts:1689-1705` process-exit handlers | rejection reaches the surrounding promise catch and is logged | not silent; Item 57 owns result-bearing callback parity | +| `packages/runtime-core/src/native-client.ts:81,170-200` cleanup catches | child kill/stdin-destroy race cleanup, not listener dispatch | no Item 54 edit | +| `packages/runtime-core/src/frame-stream.ts:125-127` frame listener | exception propagates | not swallowed | + +This audit found no second swallowed TypeScript listener exception in the +client scope.

Current `McpServerConfig` variants at `session.rs:560-576` +contain only `String`, `Vec`, and `BTreeMap`, so their derived +serializer is effectively infallible today. The defect is therefore a latent, +source-proven loss rather than a runtime failure constructible through the +current public enum. It still must be removed: a future field serializer must +not silently change the caller's server list. + +The sidecar's responsibility begins after serialization: + +- create paths parse `clientCapabilities` and `mcpServers` at + `crates/agentos-sidecar-core/src/engine.rs:1419-1420,3419-3420`; +- `parse_json_text` at `engine.rs:4551-4554` returns a typed invalid-state error + for malformed wire JSON; and +- `crates/agentos-sidecar/tests/acp_wrapper_conformance.rs:1132-1155` proves + malformed MCP JSON is rejected before browser adapter resources are spawned. + +That sidecar test stays where it is. It proves a distinct semantic boundary and +cannot test a Rust value being dropped before the request is sent. + +## Exact production edits + +### TypeScript: structured warning without routing failure + +In `SidecarProtocolClient.dispatchEvent`, replace the empty catch with: + +```ts +try { + listener.handler(event); +} catch (error) { + console.warn("[agent-os] sidecar event listener failed", { + error, + ownership: event.ownership, + payloadType: event.payload.type, + }); +} +``` + +Required behavior: + +- preserve per-listener synchronous isolation; +- warn once for each thrown listener invocation; +- retain the thrown value as-is, including non-`Error` throws; +- include ownership and payload type, but **not** the complete payload; +- continue to every sibling listener; +- continue waiter matching and event buffering; and +- do not close/fail the transport or reject unrelated requests. + +Do not add a public `onEventListenerError` option, tracing configuration, rate +limiter, async listener contract, or client-side error queue. A small structured +`console.warn` is the existing repository pattern and keeps the client simple. + +### Rust: preserve Item 46 presence and serialize all-or-error + +Item 46 changes `CreateSessionOptions.mcp_servers` to +`Option>`. Item 54 lands later, so its correct target is: + +```rust +let mcp_servers = options + .mcp_servers + .as_ref() + .map(|servers| { + serde_json::to_string(servers).map_err(|error| { + ClientError::InvalidArgument(format!( + "failed to encode MCP servers: {error}" + )) + }) + }) + .transpose()?; +``` + +This preserves the Item 46 contract: + +- `None` -> omitted wire field, so the sidecar applies its default; +- `Some(vec![])` -> present JSON `[]`; +- `Some(nonempty)` -> the complete array in caller order or a typed error. + +`InvalidArgument` already exists at `crates/client/src/error.rs:47-49` and is +the correct category: explicit caller input could not be represented before a +sidecar request existed. Do not report a local serializer failure as +`ClientError::Sidecar`. + +Item 46's research deliberately leaves the current `filter_map` behavior for +Item 54. Inspect its landed projection helper and put the expression above at +that final serialization boundary. The required Item 54 result is one +whole-list serialization, no per-entry `.ok()`/`filter_map`, and +`ClientError::InvalidArgument` on failure. Do not cite Item 46 as inherited +completion of the Rust half: Item 46 owns presence, while Item 54 owns +all-or-error conversion. + +Do not restore today's `is_empty() -> None` behavior after Item 46. That would +erase explicit presence and regress the earlier item. + +## Before evidence and after tests + +### TypeScript focused test + +Add coverage beside “runs the response hook before a following event is +dispatched” in `packages/runtime-core/tests/protocol-client.test.ts`. Import +`vi`, use `MemoryFrameTransport`, and register two matching listeners in order: +the first throws `new Error("listener exploded")`; the second records delivery. + +One focused test should cover both immediate and buffered routing: + +1. spy on `console.warn` with a no-op implementation; +2. register the throwing listener and a sibling listener; +3. start `waitForEvent` before emitting the first structured event; +4. emit it and assert the transport callback does not throw, the sibling runs + exactly once, the waiter resolves to the same event, and the warning is + called once with the exact message plus `{ error, ownership, payloadType: + "structured" }`; +5. emit a second matching event with no waiter, then start `waitForEvent` and + assert it resolves from the bounded buffer despite the listener exception; +6. assert the sibling and warning each ran exactly twice; and +7. restore the spy and dispose the client in `finally` so a failed assertion + cannot leak the silence timer. + +**Before validation:** the sibling/waiter/buffer assertions already pass, while +the warning assertion fails because the catch is empty. This directly captures +the original behavior without deliberately breaking the transport. + +**After validation:** all assertions pass, proving visibility and continuity. +A sidecar test cannot throw a host JavaScript function, so this test correctly +stays in runtime-core. + +### Rust focused tests and inherited evidence + +Run Item 35's `acp_decode_tests` unchanged. They are the before/after proof for +the original session losses: + +- `config_values_preserve_order_and_fail_at_the_original_index`; +- `malformed_present_optional_state_is_typed_while_omission_stays_none`; +- `required_mode_and_config_fields_cannot_default_to_empty_values`; and +- `malformed_json_text_uses_the_same_field_and_index_context`. + +For MCP, extend Item 46's presence/request-projection test (rather than adding a +second request builder) so it proves `None`, `Some([])`, and a non-empty +two-entry list reach the wire distinctly under Item 54's final serializer. Its +non-empty fixture should contain both variants, non-empty args/env/headers, and +assert array length, caller order, and complete nested fields after JSON decode. + +The current enum cannot trigger `Serialize::serialize` failure, so do not claim +a fabricated public runtime reproducer. The exact before evidence is the live +`filter_map(|server| serde_json::to_value(server).ok())`, which definitionally +discards `Err`. The exact after evidence is one complete-Vec +`serde_json::to_string` operation returning `Result`, plus a source audit that +the create-session MCP path contains no `filter_map`/`.ok()`. + +Do not add a production generic serializer, a fake public MCP variant, or a +brittle repository-wide source-text test solely to manufacture an otherwise +unconstructible serde error. If Item 46 already extracted a small private +serialization seam for its presence matrix, Item 54 may add a test-only custom +`Serialize` failure there and assert `ClientError::InvalidArgument`; otherwise +the static before evidence and complete-list wire test are the honest coverage. + +Before marking Item 54 complete, update its tracking checklist with exact test +names/revisions: + +- **before:** the TypeScript test failed only on missing warning; Item 35 tests + identify the prior session conversion failures; the MCP `filter_map(...ok())` + source audit demonstrates latent element loss; +- **after:** the TypeScript listener-continuity/warning test passes; Item 35 ACP + decode tests pass; the Item 46 request projection passes with Item 54's + whole-list serializer and contains no `.ok()`/`filter_map`; and +- **complete:** one dedicated Item 54 JJ revision is validated and the row is + marked `done`. + +## Dependencies, risks, and non-goals + +- **Numbered sequencing:** create Item 54 as one revision directly after Item + 53. Items 35 and 46 are already ancestors by then. +- **Item 35:** its `AcpDecode` changes and tests are required inherited behavior; + do not duplicate them. +- **Item 46:** preserve its `Option>` and optional nested MCP fields. Its + research explicitly leaves lossy conversion removal to Item 54. +- **Log volume:** a listener that throws on every event will warn on every + invocation. Rate limiting would add client policy/state and is out of scope. +- **Sensitive data:** never include the full event payload. The error object may + itself contain caller-chosen content, which is standard for host-visible + programming-error logging. +- **Transport health:** a listener error must not close the transport, reject a + request, skip siblings, consume/strand a waiter, or bypass the event buffer. +- **MCP/default policy:** the sidecar continues to own all MCP defaults and ACP + semantics. The Rust edit is serialization of explicit typed input only. +- **No protocol churn:** no schema, generated binding, sidecar, actor, or + TypeScript public API edit is required. +- **Separate listener items:** stdout/stderr fan-out is Item 69; legacy + permission interpretation is Item 52; result-bearing exit callbacks are Item + 57. + +## Dedicated one-item JJ scope + +Create exactly one Item 54 revision, directly after Item 53, with a description +such as: + +```text +fix(client): surface listener and conversion failures +``` + +Expected paths: + +```text +packages/runtime-core/src/protocol-client.ts +packages/runtime-core/tests/protocol-client.test.ts +crates/client/src/session.rs +docs/thin-client-migration.md # Item 54 evidence/status only +``` + +`crates/client/src/session.rs` is required Item 54 scope after Item 46 lands; the +comment above is not conditional.

Pointing the Core +README at that output would falsely imply it documents the low-level Core +surface. Expanding TypeDoc to multiple packages requires a navigation and +public-surface decision and is outside this cleanup. + +## Exact implementation + +### 1. Add failing verifier coverage first + +Edit `scripts/verify-thin-client-docs.mjs`. + +Add the Core README as a fixed guidance input beside the root README: + +```js +const fixedGuidancePaths = ["README.md", "packages/core/README.md"]; + +for (const relativePath of fixedGuidancePaths) { + const path = join(root, relativePath); + if (existsSync(path)) files.push({ path, relativePath }); +} +``` + +Add path-scoped rules.

Preserve all +existing permission diagnostics and counts. + +Edit `scripts/verify-thin-client-docs.test.mjs` in the same step: + +1. Add a valid `packages/core/README.md` fixture containing the documentation + link and declaration-source paragraph. +2. Teach `writeValidFixture` to write `README.md` and paths beginning with + `packages/` directly; website fixture paths keep their current mapping. +3. Add a stale Core README fixture with the two inventory headings, + `commandDirs`, backticked `AgentConfig`, and the obsolete registry fields on + distinct lines. Assert the four rule IDs, Core path, and representative line + numbers. +4. Add a missing-source-statement case that asserts + `core-readme-declaration-source`. +5. Retain `passes on the current tree`; after adding the rules but before + changing the README, this test must fail. + +Do not snapshot every current method or export in the verifier. That would +recreate the inventory in test code. + +### 2. Replace the copied inventory + +In `packages/core/README.md`, delete everything from `## API Reference` at line +55 through `HostDirBackendOptions` at line 204. Replace it with: + +```md +## Documentation + +See the [agentOS documentation](https://agentos-sdk.dev/docs) for guides. +The emitted TypeScript declarations (`dist/index.d.ts`) shipped with this package +are the authoritative public API.

This note does not change production +code, tests, or the Item 56 tracker status. + +## Recommendation + +Replace `CronDispatchEvent` with a typed sidecar-initiated +`CronDispatchRequest`/`CronDispatchResultResponse` exchange. Give each pending +dispatch a sidecar-owned monotonic cursor, retain the pending FIFO and last +acknowledged cursor in the opaque cron snapshot, and allow only the FIFO head to +have one in-flight reverse request. Make clients cache the result for the last +cursor so retransmission returns the same answer without applying the alarm or +invoking a callback twice. For an actor, persist the opaque pending snapshot as +a write-ahead record before applying host effects and returning the ack. + +Priority: **P0**. Confidence: **high** that the current event is lossy and that a +correlated reverse request is the right boundary. Confidence is **medium-high** +on the exact implementation size because the native sidecar already has a +non-blocking sidecar-request queue, while the browser wire dispatcher currently +accepts only host `RequestFrame`s and returns only `EventFrame`s from +`pollEvent`. Worse, the production `ConvergedSidecarHandle` exposes only +`pushFrame`; its factory drops the WASM `pollEvent` method entirely. Browser +reverse-frame delivery and its production pump must therefore land in this +revision or Item 56 must be stacked after Item 73's asynchronous browser frame +boundary. A browser unit test that calls `BrowserWireDispatcher::poll_event_bytes` +directly is not sufficient parity evidence. + +Do not solve this by enlarging the Rust control-event log, the TypeScript event +buffer, or the cron lifecycle broadcast. Those remain bounded observer streams +and cannot turn an unacknowledged state transition into reliable delivery. + +## Original issue and exact failure path + +The tracker entries are at `docs/thin-client-migration.md:102,189,281`. + +The scheduler commits the state transition before the host sees it: + +1. `CronScheduler::complete` removes the active run, decrements its job's + running count, may create the queued follow-on run, and returns the new alarm + and lifecycle records (`crates/native-sidecar-core/src/cron.rs:369-396`). +2. Native exec exit handling performs that completion and then wraps the result + in a fire-and-forget `CronDispatchEvent` + (`crates/native-sidecar/src/service.rs::handle_cron_execution_event`, around + lines 2241-2311). Browser does the same in + `BrowserWireDispatcher::execution_event_to_frame`, around lines 2350-2412. +3. The Rust transport categorizes the event as ordinary control traffic at + `crates/sidecar-client/src/transport.rs:920-939`. Its log is deliberately + bounded to 4,096 entries and roughly one negotiated maximum frame + (`transport.rs:24-40`), so an older cron dispatch can be evicted. +4. The Rust client consumes the event from the same ACP control pump at + `crates/client/src/agent_os.rs:639-710`. On lag, Item 22 now fails the route, + clears the alarm, and stops cron operations (`agent_os.rs:693-733`), but the + already-committed sidecar completion is not replayed. +5. TypeScript receives the same observer event in + `packages/core/src/agent-os.ts:2401-2436`. The generic runtime event buffer is + also bounded (`packages/runtime-core/src/event-buffer.ts:126-169`), and event + listeners have no acknowledgement (`packages/runtime-core/src/protocol-client.ts:367-390`). + +The concrete observable loss today is an updated absolute alarm and completion +record after a sidecar-owned exec exits. The current native and browser exec +paths call `start_cron_runs` before emitting the event, so the `runs` list is +normally empty for an exec job: a queued run has the same serializable exec +action and is launched in the sidecar. The schema nevertheless permits host +callback runs in this event, and both clients execute any such run without an +ack. The tracker wording is therefore correct as a protocol invariant, but the +strongest current regression is the stale-alarm/stranded-completion case, not a +normal exec-to-callback transition. + +Synchronous `WakeCron`, `CompleteCronRun`, and `ImportCronState` responses are a +separate cancellation window: the response is correlated, but a caller can +drop its future after the sidecar commits and before `consume_dispatch` runs. +Item 56 should reuse the same cursor consumer for those responses where +practical, but the minimum P0 fix is to remove asynchronous committed state from +the unacknowledged `EventPayload` route. + +## Protocol shape + +Edit `crates/sidecar-protocol/protocol/agentos_sidecar_v1.bare:977-1048` and +regenerate both Rust and TypeScript bindings. Replace the event with these +generated wire concepts (field spelling follows the BARE schema): + +```text +type CronRunResult struct { + runId: str + error: optional +} + +type CronDispatchRequest struct { + cursor: u64 + alarm: CronAlarm + runs: list + state: JsonUtf8 +} + +type CronDispatchResultResponse struct { + cursor: u64 + runResults: list + error: optional +} + +type CronLifecycleEvent struct { + event: CronEventRecord +} +``` + +Add `CronDispatchRequest` to `SidecarRequestPayload` and +`CronDispatchResultResponse` to `SidecarResponsePayload`. Remove +`CronDispatchEvent` from `EventPayload`; replace it with the observer-only +`CronLifecycleEvent`. Retaining alarm/runs in an event path would preserve the +ambiguous, lossy route. Lifecycle records are notifications, not scheduler +authority: they may use the existing bounded control-event delivery and surface +a typed lag error without disabling cron. This separation also prevents up to +4,096 bounded 64-KiB error records from making the 8-MiB durable scheduler +snapshot impossible to encode. + +`state` is an opaque snapshot produced by the sidecar after the dispatch is +queued. Ordinary clients ignore it. A durable host may store it verbatim before +answering, which lets the actor recover the pending cursor and deferred work +without inspecting scheduling state. This is the only extra host hook needed; +do not teach the actor or either SDK to parse the snapshot. + +The request payload for one cursor is immutable. Retransmitting a cursor must +carry byte-equivalent alarm/run/state fields. To preserve that invariant +without adding a second scheduler transaction log, reject schedule, cancel, +wake, and import mutations for that VM with a typed `cron_dispatch_pending` +response until the head is acknowledged. Concurrent run completions must still +commit into later immutable FIFO entries, because up to the active-run bound may +exit while the head is in flight. `list` and `export_state` remain read-only and +may proceed. This is deliberate fail-closed backpressure: silently mutating a +dispatch that a client may already have applied would make cursor deduplication +false. A future optimization can queue mutations inside the scheduler, but must +not weaken the immutable-cursor rule. + +The response's top-level `error` means “the host could not apply this dispatch” +(for example its durable state or alarm hook failed). Per-run callback failures +belong in `runResults`. The sidecar must validate the cursor, require exactly +one result for every host callback run and no unknown run IDs, and leave the +dispatch pending on a top-level error or malformed response. The clients must +always return this typed result payload; they must not fail the generic callback +future, because Rust's current `dispatch_sidecar_request` only logs callback +errors and sends no frame. + +Generated/compatibility conversion edits are required in +`crates/sidecar-protocol/src/protocol.rs:1030-1138,1445-1464,1847-1878` and +`crates/sidecar-protocol/src/wire.rs:1040-1125`. Item 45 may later delete the +compatibility layer, but Item 56 cannot leave the two protocol representations +divergent. Regenerate `packages/runtime-core/src/generated-protocol.ts` with the +existing `pnpm --dir packages/build-tools build:protocol` path; do not edit that +generated file by hand. + +## Sidecar state-machine edits + +### Shared scheduler: `crates/native-sidecar-core/src/cron.rs` + +Add a bounded pending-delivery state beside `active_runs` around lines 172-223: + +- `next_dispatch_cursor: u64`; +- `last_acked_dispatch_cursor: Option`; +- a FIFO of immutable `PendingCronDispatch` records containing the cursor, + alarm and host runs; the adapter's one in-flight delivery + caches the fully built wire request (including its exported opaque snapshot) + for byte-equivalent retransmission, avoiding a recursive snapshot-inside- + snapshot representation; and +- explicit deferred-delivery state (or, preferably, leave an overlap-queued job + queued until ack) so import cannot return pending work as a fresh active run. + +The queue must be bounded by `MAX_ACTIVE_CRON_RUNS` (currently 4,096), warn at +80%, and use a typed scheduler error naming the limit. Once any dispatch is +pending, do not start new due/overlap work: concurrent executions already in +flight can contribute at most the active-run bound, while pausing `wake` and +deferring overlap follow-ons prevents an unacknowledged host from creating an +unbounded completion backlog. A later applied alarm may already be due; the +normal host timer will immediately wake it after the queue drains. + +Split the current completion operation (`cron.rs:369-396`) into the existing +request/response completion and an asynchronous completion operation that: + +1. commits the completed run; +2. records its alarm/host runs under the next cursor and returns lifecycle + records separately as best-effort observer events; +3. retains an overlap-queued follow-on as queued rather than allocating or + launching its next run before the cursor is acknowledged; and +4. exposes only the head pending dispatch. + +Add scheduler methods with semantics equivalent to: + +```rust +complete_async(request, now_ms) -> Result +pending_dispatch() -> Option +ack_dispatch(cursor, run_results, now_ms) -> Result +``` + +`CronDispatchAck` should distinguish `Applied { runs, events }` from +`Duplicate`; returning the deferred runs again on a duplicate ack would execute +them twice. `ack_dispatch` must be idempotent for exactly the last acknowledged +cursor, reject a future/stale cursor with a typed error, remove the head only +after validating the whole response, apply callback results through the same +completion logic, and return newly released work once for the sidecar adapter +to execute. Never let a client mutate the alarm, job state, overlap policy, or +cursor. + +Bump `CRON_STATE_VERSION` at `cron.rs:26` and extend +`CronStateSnapshot`/`export_state`/`import_state` at lines 178-210 and 416-600 +with both cursor counters, pending records, and deferred-delivery state. On +import, pending records must be replayed first; deferred sidecar-owned runs must +not also appear in `CronStateImportedResponse.runs`. This closes an existing +sharp edge in which all imported active actions are currently returned +generically at lines 553-599, even when the action is exec and belongs in the +sidecar. Reject snapshots with duplicate/non-monotonic cursors, a last-acked +cursor not below the pending head, unknown run/job references, or a combined +active-plus-pending count above `MAX_ACTIVE_CRON_RUNS`. + +Keep the whole serialized snapshot under `MAX_CRON_STATE_BYTES` (8 MiB). Store +run/job IDs in pending records and reconstruct the action from the authoritative +job when possible; cloning a maximum-size action once per active run could +otherwise defeat the snapshot bound. + +Add unit coverage in the existing `#[cfg(test)]` module in this file for cursor +allocation, duplicate acknowledgement, future-cursor rejection, paused wakes, +queue bounds, snapshot round-trip, and “pending deferred run is not returned as +a second fresh run on import.” + +### Native adapter: `crates/native-sidecar/src/service.rs` + +Replace the `CronDispatchEvent` construction in +`handle_cron_execution_event` (currently lines 2241-2311) with a +non-blocking reverse-request state machine: + +- correlate `(request_id -> vm_id, cursor)` and one cached in-flight request per + VM beside `cron_schedulers`/`cron_process_runs` in `NativeSidecar`; +- queue the head through `queue_wire_sidecar_request` (currently line 3742); +- consume matching responses through `accept_wire_sidecar_response` and + `take_wire_sidecar_response` (currently lines 3824 and 3844); +- on a valid ack, call `ack_dispatch`, pass its deferred work to + `start_cron_runs` (`service.rs:1598-1710`), and queue the next cursor if one + exists; and +- on a top-level host error, retain the cursor and retry it with a sidecar-owned + bounded backoff only after that response proves the prior handler finished. + Never allocate a second in-flight request for one cursor. + +Use this existing queued request machinery rather than the blocking +`SharedSidecarRequestClient::invoke` at `crates/native-sidecar/src/state.rs:221-245`. +The cron handler may await a user callback and a durable actor write; blocking +the sidecar event loop would strand unrelated requests. The stdout writer +already prioritizes sidecar response/control frames, and the reader already +accepts `SidecarResponseFrame`s independently. + +`crates/native-sidecar/src/stdio.rs::handle_protocol_frame` is the production +ack continuation point. Immediately after accepting a `SidecarResponseFrame`, +take any matching cron response, apply it, launch the once-released sidecar +work, and flush the next head. The periodic process-event pump must also call a +small `queue_pending_cron_dispatches` helper so restored pending cursors are +emitted even when no new host request arrives. Keep this work non-blocking with +respect to host callbacks; only `start_cron_runs` may await sidecar-owned session +work after the host has already answered the reverse request. + +Remove the obsolete `CronDispatchEvent` import and make VM/session disposal +purge the cursor correlation and in-flight delivery exactly where +`cron_schedulers`/`cron_process_runs` are purged in `reclaim_vm_tracking` and the +session/connection cleanup paths. This requires a bounded +`SidecarResponseTracker::abandon_request(request_id)` API in +`crates/sidecar-protocol/src/protocol.rs`, plus removal from +`outbound_sidecar_requests`, `completed_sidecar_responses`, and their order/gauge +state. Without that, disposal leaks a pending tracker slot for every unanswered +cursor. Late responses should then follow the existing benign stale-response +policy. + +The native stdout path already gives queued sidecar requests their own bounded +frame route; do not put cron back in `EventFrame`. Queue overflow must preserve +the scheduler's pending cursor and return/log a typed limit error naming +`MAX_OUTBOUND_SIDECAR_REQUESTS`; the next event-pump tick may retry queueing the +same cursor after capacity is available. + +Do not invent a dispatch timeout in this item. If a host handler never returns, +the pending FIFO stays bounded and cron pauses, but retrying it concurrently +could invoke a callback twice because the current callback protocol has no +expiry/cancellation acknowledgement. Item 68 is the dependency for adding a +bounded authoritative timeout later. Item 56 may safely retry a returned +top-level error (initial 100 ms, capped at 30 s is sufficient); the client must +not cache error responses, and its effect order must guarantee no callback ran +before that error. + +### Browser adapter: `crates/native-sidecar-browser/src/wire_dispatch.rs` + +The browser currently hard-rejects any input frame other than `RequestFrame` +at lines 159-167, stores only `pending_events` at lines 87-136, and returns only +`EventFrame` from `poll_event_bytes` at lines 200-210. That is the main +implementation risk. + +Extend the dispatcher to: + +- accept both `RequestFrame` and `SidecarResponseFrame`; +- keep `pending_events` as the lossy observer queue, but add a separate bounded + one-head-per-VM reverse-request queue/tracker (bounded by the configured + `max_vms`, itself defaulted to `DEFAULT_MAX_VMS`); prioritize that queue over + observer events; +- change `handle_request_bytes` to return an optional immediate frame: a host + `RequestFrame` returns its `ResponseFrame`, while a host + `SidecarResponseFrame` is consumed and returns no response; +- rename/broaden `poll_event_bytes` and the WASM `pollEvent` export to + `poll_frame_bytes`/`pollFrame`, returning either `SidecarRequestFrame` or + `EventFrame` (the shared JS frame classifier already understands both); and +- apply the matching cursor response before releasing deferred runs. + +Then replace the `CronDispatchEvent` built by +`BrowserWireDispatcher::execution_event_to_frame` at lines 2350-2412 with the +shared pending-dispatch request. Keep `MAX_PENDING_REQUEST_EVENTS` for observer +events, but give cron dispatch its own one-per-cursor correlation and the shared +scheduler bound; it must not compete with the lossy observer queue. + +Do not leave browser cron on the old event as a temporary exception. Project +guidance requires native/browser and Rust/TypeScript wire behavior to remain in +lockstep. + +This Rust/WASM work is not sufficient by itself. Today +`packages/runtime-browser/src/default-sidecar.ts` and +`packages/browser/src/converged-sidecar.ts` return only `pushFrame`; they discard +the WASM poll method, and `PushFrameSidecarTransport` assumes every write is a +host request with an immediate response. Stack Item 56 after Item 73 and use its +asynchronous production frame pump. If Item 56 lands first, include the minimum +equivalent boundary in the same revision: expose `pollFrame`, continuously drain +it on the main thread, dispatch `SidecarRequestFrame` through the shared +`SidecarProtocolClient` handler, and write the resulting +`SidecarResponseFrame` back without expecting an immediate frame. Guest +SharedArrayBuffer syscalls must keep their existing synchronous request/response +`pushFrame` path. + +## Client edits + +### Rust + +In `crates/sidecar-client/src/transport.rs`, add `CronDispatchRequest` to +`sidecar_request_key` at lines 1078-1084. It will then use the already +correlated, prioritized `SidecarRequestFrame` path at lines 941-985 rather than +the bounded control log. + +In `crates/client/src/agent_os.rs`: + +- add a weak cron router scoped to `AgentOsSidecar` in + `crates/client/src/sidecar.rs`, keyed by the full + `(connection_id, session_id, vm_id)` ownership tuple; +- register a `"cron_dispatch"` wire callback unconditionally after the VM's + `AgentOsInner` exists (the current creation point is lines 385-398); +- route by exact VM ownership to `CronManager`; and +- replace the `CronDispatchEvent` arm in the control pump with an observer-only + `CronLifecycleEvent` arm that publishes one record to `cron_events()` without + touching alarms, callbacks, or scheduler operations. + +Do not copy `VM_PERMISSION_ROUTERS`' process-global `vm_id`-only key. Separate +sidecar processes reuse `conn-1/session-1/vm-1`, and a new global map would make +reliable cron delivery cross-route between pools. The sidecar-handle-scoped map +is legitimate host transport state, is shared by sibling VMs on exactly one +transport, and can be removed only after confirmed session shutdown. + +After the event arm is gone, `fail_control_routes` at lines 716-733 should fail +ACP/session observer streams only. Remove the cron call there and the sticky +`event_route_failure`/`ensure_event_route` gates from +`crates/client/src/cron.rs:212-300,460-560,780-898`. A lagging public +`cron_events()` receiver should still receive its own typed stream error, but it +must not disable schedule/list/cancel or clear a correct alarm: authoritative +cron delivery no longer uses that observer stream. + +Refactor `CronManager::consume_dispatch` and `execute_run` at +`cron.rs:496-604` into a handler that returns `Vec` instead of +issuing `CompleteCronRunRequest` for reverse-delivered runs. Issuing a nested +host request while the sidecar is waiting for `CronDispatchResultResponse` can +deadlock; callback results must travel in that response. Keep the existing +request/response callback completion path for runs returned directly by +`WakeCronResponse` until all synchronous dispatch responses are cursorized. + +Store only `(last_cursor, last_success_response)` in `CronManager`. On the same +cursor, return the cached success without reapplying the alarm, persisting +state, or reinvoking callbacks. A higher cursor proves the +previous response was accepted and replaces the cache. Do not cache a top-level +error: the sidecar is allowed to retry it after the prior handler returns. This +is bounded deduplication, not a client-owned scheduler. + +Add a host-only optional opaque-state hook next to `CronAlarmHandler` at +`cron.rs:116-130`, for example `CronStateCommitHandler`. For a new cursor, call +the hooks in this order: (1) persist `request.state`; (2) apply the absolute +alarm; (3) invoke callbacks and collect their per-run results; (4) cache and +return the successful ack. If steps 1 or 2 fail, return a top-level error before +any callback runs. Observer lifecycle records arrive separately through +`CronLifecycleEvent`. Regular clients leave the state hook unset; the actor +supplies durable storage. Re-export the named type from +`crates/client/src/lib.rs:85-88`. + +Item 37 has landed. Preserve its result-bearing Rust callback because that is +what populates `CronRunResult.error`; do not reintroduce a unit-returning +callback or stringify a `ClientError` prefix here. + +### TypeScript + +Update `packages/runtime-core/src/callbacks.ts:14-125` and its generated mapping +tests to represent `cron_dispatch` and `cron_dispatch_result`. The existing +protocol client already dispatches a sidecar request outside the event buffer +and awaits the handler (`packages/runtime-core/src/protocol-client.ts:121-126, +342-365`), so no new TypeScript transport queue is needed on the native stdio +path. Extend `isMatchingSidecarResponsePayload` and +`errorSidecarResponsePayload` too, so a thrown handler becomes a typed +top-level cron result rather than an unhandled switch gap. + +In `packages/core/src/agent-os.ts:2804-2847`, add a `cron_dispatch` arm to the +existing VM-scoped sidecar-request handler and replace the old `cron_dispatch` +event arm in `_handleSidecarEvent` with `cron_lifecycle`, which only calls the +public listener conversion/emitter. + +In `packages/core/src/cron/cron-manager.ts:193-243`: + +- make reverse dispatch consumption async and result-bearing; +- await every callback and return its exact error string in `runResults`; +- do not call `completeCronRun` for reverse-delivered runs; +- persist nothing client-side, apply the alarm before callbacks, and turn an + alarm-driver exception into a retryable top-level error before callbacks run; +- cache only the last successful cursor/result exactly as in Rust; and +- return a top-level dispatch error when applying the alarm fails. + +The TypeScript timer alarm driver is currently synchronous, while Rust's actor +alarm hook is fallible/async. Keep ordinary TS application simple; the reverse +handler can await a `Promise.resolve` wrapper without adding schedule policy. +The TypeScript package-manager default exception is unrelated. + +## Actor hook and delivery semantics + +`crates/agentos-actor-plugin/src/vm.rs:77-97` is the required host-only bridge: +it turns the sidecar's timestamp/generation into Rivet's `schedule_at`. Preserve +it. Add the opaque state commit handler immediately beside it so +`request.state` is stored with `persistence::save_cron_state` before the actor +calls `schedule_at` or answers the dispatch request. Do not call +`export_cron_state` from inside the callback and do not parse the value. If the +write succeeds but `schedule_at` fails, the sidecar retries the same cursor and +the stored pending snapshot remains recoverable. If `schedule_at` succeeds more +than once around a retry/crash, duplicate actor wake actions are harmless only +because `CronScheduler::wake` validates the opaque alarm generation; document +and test that invariant. + +On cold boot, `ensure_vm` already imports the stored opaque state at +`vm.rs:98-119`. The extended snapshot replays its pending cursor. Actor cron +actions currently expose only exec/session, not host callback closures, so a +replayed pending dispatch can re-arm the same opaque generation and then start +deferred work once; it cannot duplicate an in-process callback that vanished +with the old process. + +Be precise about the guarantee: + +- **Within a live VM/connection:** at-most-once host application under request + retransmission, using the cursor/result cache; no alarm or run is silently + dropped. +- **Across a controlled actor cold boot from a stored pending snapshot:** the + restored sidecar exposes the same cursor, the live client applies it once, + and stale/duplicate wake actions remain harmless because the scheduler + validates alarm generation. +- **Across an arbitrary crash before the actor stores the post-transition + snapshot, or after ack but before the existing lifecycle-event pump persists + the post-ack snapshot:** strict exactly-once execution is impossible without a + transactional durable sidecar/actor log. Do not claim otherwise. The design + narrows the commit point to “persist opaque pending state, then apply host + effects, then ack” and provides at-least-once recovery for those crash + windows.

That must also become an `EventStreamClosed` callback result. + +The existing `wait_process` implementation at lines 501-519 is the semantic +reference for retained states: success returns the code and retained route +failure returns its typed `ClientError`. Its defensive raw-watch-close branch is +still a generic `ClientError::Sidecar`; Item 57 should make that branch the same +typed `EventStreamClosed { context: "process exit" }` delivered to a callback. + +### Rust additionally drops the protocol's terminal error + +The authoritative BARE shape at +`crates/sidecar-protocol/protocol/agentos_sidecar_v1.bare:969-975` is: + +```text +type ProcessExitedEvent struct { + processId: str + exitCode: i32 + stdout: optional + stderr: optional + error: optional +} +``` + +`RejectedResponse` is exactly `{ code: str, message: str }` at lines 809-812. +The error is not an alternate event and it does not remove `exitCode`; consumers +must check the optional error before treating the integer as success. + +Finite Rust `exec` already does this correctly in `apply_exec_event` at +`crates/client/src/process.rs:930-965`: `Some(error)` becomes +`ClientError::Kernel { code, message }`. The spawned-process pump does not. Its +`ProcessExitedEvent` match at lines 831-833 ignores `exited.error` and stores +only `ProcessExit::Exited(exited.exit_code)`. Consequently both +`wait_process` and a future result-bearing `on_process_exit` can report `Ok(code)` +for a terminal frame that the sidecar marked failed. + +Represent this internally as a cloneable `ProcessExit::Failed { code, message }` +and map it to the existing public `ClientError::Kernel`. Do not store a generic +string and do not invent a new protocol error taxonomy. + +### TypeScript has the callback defect but already handles terminal wire errors + +TypeScript already retains a compact union in +`packages/core/src/agent-os.ts:1268-1289`: + +```ts +type ProcessRoute = + | { state: "running"; /* host routes */ } + | { state: "exited"; exitCode: number } + | { state: "failed"; error: Error }; +``` + +But `RunningProcessRoute.exitHandlers` is a +`Set<(exitCode: number) => void>`. `_trackProcess` at +`agent-os.ts:1642-1704` behaves as follows: + +- successful `proc.wait()` snapshots and invokes handlers with the exit code; +- rejected `proc.wait()` clears every exit handler, stores `{ state: "failed", + error }`, and only calls `console.error`. + +`onProcessExit` at `agent-os.ts:1785-1799` invokes late success subscribers +synchronously, but throws a retained failed-route error from the registration +call instead of delivering it to the callback. A subscriber registered while +the process is running receives no call if the route later fails. + +`waitProcess` at lines 1801-1808 already resolves/rejects from the same retained +route and is the TypeScript semantic reference. + +The source of a failed route is intentionally broader than event-route loss. +`NativeSidecarKernelProxy.runEventPump` at +`packages/core/src/sidecar/rpc-client.ts:835-846` checks the converted +`process_exited.error_code`, constructs an `Error` with the authoritative code +and message, and calls `failProcess`; `ManagedProcess.wait()` then rejects with +that exact object. Runtime-core's live shape is at +`packages/runtime-core/src/event-buffer.ts:32-40`, and its conversion from the +generated optional `RejectedResponse` is at lines 380-397. + +Therefore `_trackProcess`'s rejected `proc.wait()` path covers transport/event +pump failures and sidecar terminal failures alike. Item 57 must forward the exact +retained `Error` to early and late callbacks. It must not parse `error.code` or +try to infer whether the cause was transport, capture policy, or guest execution. + +## Public outcome contract + +### Rust + +In `crates/client/src/process.rs`, add a public alias near the other supporting +types: + +```rust +/// Once-only terminal outcome delivered by `on_process_exit`. +pub type ProcessExitResult = std::result::Result; +``` + +Change the handler parameter to: + +```rust +handler: impl FnOnce(ProcessExitResult) + Send + 'static +``` + +Re-export `ProcessExitResult` from `crates/client/src/lib.rs` beside +`SpawnHandle` and `SpawnOptions`. + +Using the SDK's existing `ClientError` is important. `EventStreamLagged` retains +its `skipped` count and `EventStreamClosed` retains context; a string or optional +integer would lose that information. `ClientError` need not become `Clone`: +internal `ProcessExit` remains cloneable for each watch subscriber, and every +callback independently maps its cloned state to one owned error. + +### TypeScript + +In `packages/core/src/runtime.ts`, add an exported discriminated result near +`ManagedProcess`: + +```ts +export type ProcessExitResult = + | { ok: true; exitCode: number } + | { ok: false; error: Error }; +``` + +Import it into `packages/core/src/agent-os.ts`, use it for +`RunningProcessRoute.exitHandlers`, `_trackProcess`, `spawn`, and +`onProcessExit`, and export it from `packages/core/src/index.ts`. + +The discriminated union prevents impossible states: failure has no fabricated +code and success has no optional error. Do not use `number | null`, `-1`, `0`, +or `1` as a failure marker. Do not use an error-first pair with two nullable +arguments. + +The error should be the exact retained `Error` object. Do not replace it with a +new anonymous wrapper. Item 63 later upgrades terminal code-bearing failures to +an exported structured error; forwarding the exact object here makes that +upgrade automatically visible to callback consumers. + +## Exact production edits + +### `crates/client/src/agent_os.rs` + +Extend the private, cloneable terminal union: + +```rust +pub(crate) enum ProcessExit { + Exited(i32), + Failed { code: String, message: String }, + EventStreamLagged { skipped: u64 }, + EventStreamClosed, +} +``` + +Update the `ProcessEntry.exit_tx` comment from “`Some(code)`” to “a terminal +outcome.” This is client correlation state, not client-owned policy. + +### `crates/client/src/process.rs` + +Add a small pure mapper used by `run_spawn_events` and its unit tests: + +```rust +fn process_exit_from_event(exited: &wire::ProcessExitedEvent) -> ProcessExit { + match &exited.error { + Some(error) => ProcessExit::Failed { + code: error.code.clone(), + message: error.message.clone(), + }, + None => ProcessExit::Exited(exited.exit_code), + } +} +``` + +The matching event branch sends this mapped value instead of unconditionally +sending `Exited(exited.exit_code)`. Extend `process_exit_result` with: + +```rust +ProcessExit::Failed { code, message } => Err(ClientError::Kernel { code, message }), +``` + +This matches finite `exec` and TypeScript `ManagedProcess.wait()` without +changing the sidecar or wire schema. + +Refactor the duplicate immediate/asynchronous match into one private helper that +takes the subscribed `watch::Receiver` and the result-bearing `FnOnce`. The +helper is also the deterministic unit-test seam: + +```rust +fn subscribe_process_exit( + mut rx: watch::Receiver>, + handler: impl FnOnce(ProcessExitResult) + Send + 'static, +) -> Subscription { + if let Some(exit) = rx.borrow().clone() { + handler(process_exit_result(exit)); + return Subscription::noop(); + } + + let task = tokio::spawn(async move { + loop { + match rx.changed().await { + Ok(()) => { + let Some(exit) = rx.borrow().clone() else { + continue; + }; + handler(process_exit_result(exit)); + return; + } + Err(_) => { + handler(Err(ClientError::EventStreamClosed { + context: "process exit", + })); + return; + } + } + } + }); + Subscription::new(move || task.abort()) +} +``` + +`pid` is not needed once tracing-only failure branches are removed. The callback +itself is now the primary failure delivery path. If callback panics, normal Rust +task panic reporting applies; do not catch panics or invent callback policy. + +Then make `AgentOs::on_process_exit` perform only the PID lookup/subscription and +delegate to the helper. Preserve these semantics: + +- unknown PID returns `ClientError::ProcessNotFound` without invoking the + callback; +- a retained outcome invokes synchronously and returns `Subscription::noop()`; +- a live outcome invokes exactly once; +- dropping the returned subscription before terminal observation aborts the + task and does not invoke the callback; and +- success, lag, close, and unexpected watch-channel closure are mutually + exclusive outcomes. + +Use `ClientError::EventStreamClosed { context: "process exit" }` for an +unexpected closed watch in both `subscribe_process_exit` and `wait_process`, so +the callback and future APIs agree on the same typed terminal outcome. + +Update stale comments at `process.rs:305-307`, `agent_os.rs:68-69`, and the +method docs at `process.rs:445-448` so they say “terminal outcome,” not +`Some(code)`/exit code only. + +Do not change the sidecar protocol. Do not alter event ownership/process-ID +filtering, capture semantics, or route-failure cleanup. The necessary Rust +changes are limited to preserving data already present in the received terminal +event and delivering existing client route failures to the host callback. + +### `packages/core/src/agent-os.ts` + +Change every exit-handler set/signature from `(exitCode: number) => void` to +`(result: ProcessExitResult) => void`. + +In `_trackProcess`'s success branch, keep compact route replacement and pruning +before callback delivery, then invoke the captured handlers with: + +```ts +{ ok: true, exitCode: code } +``` + +In the rejection branch, normalize the rejection exactly once, snapshot the +handlers before clearing them, store the same error in the compact failed route, +prune, and invoke each captured handler with: + +```ts +{ ok: false, error: routeError } +``` + +Retain the current `console.error` for a process wait failure even when no exit +handler is installed. The host-visible log is still required for an +unobserved/background failure. + +`onProcessExit` should become: + +```ts +onProcessExit( + pid: number, + handler: (result: ProcessExitResult) => void, +): () => void { + const entry = this._processes.get(pid); + if (!entry) throw new Error(`Process not found: ${pid}`); + if (entry.state === "exited") { + handler({ ok: true, exitCode: entry.exitCode }); + return () => {}; + } + if (entry.state === "failed") { + handler({ ok: false, error: entry.error }); + return () => {}; + } + entry.exitHandlers.add(handler); + return () => entry.exitHandlers.delete(handler); +} +``` + +Thus registration itself throws only for an unknown/expired PID. A known failed +process is a terminal callback result, matching Rust and late success behavior. + +Do not change `waitProcess`, stdout/stderr subscriptions, or the sidecar event +pump in this item. Item 69 owns per-listener isolation for shared-sidecar +stdout/stderr callbacks. Exit-handler exception isolation is not the route-loss +contract in Item 57; avoid expanding this revision unless a focused callback +test exposes a required safety regression. + +### Public call sites + +Update the only current repository example and test call sites found by exact +search: + +- `examples/core/vm.ts:53` should branch on `result.ok` and log either the exit + code or error; +- `packages/core/tests/spawn-flat-api.test.ts:30-35` should resolve a + `ProcessExitResult`, assert `ok`, then inspect `exitCode`; and +- `packages/core/tests/leak-agent-os-processes.test.ts:98-100,139-175` should + expect the success object rather than a bare number. + +There are no repository callers of the public Rust `AgentOs::on_process_exit`; +the similarly named kernel process-table hook is an unrelated internal PID +cleanup callback and must not change. `website/src/content/docs/docs/core.mdx` +embeds `examples/core/vm.ts` through `CodeSnippet`, so the example edit updates +the rendered process documentation without duplicating inline code. + +Do not retain an overload accepting `(exitCode: number) => void`. The protocol +and SDKs ship in lockstep with no compatibility guarantee, and an overload +would preserve the exact success-only ambiguity being removed. + +## Focused before/after tests + +### Rust unit tests: `crates/client/src/process.rs` + +Test the extracted `subscribe_process_exit` helper with real watch channels and +oneshot observation: + +1. **Protocol terminal failure mapper:** build a `wire::ProcessExitedEvent` + whose `exit_code` is `0` but whose `error` is + `RejectedResponse { code: "capture_failed", message: "capture failed" }`. + Assert `process_exit_from_event` followed by `process_exit_result` returns + `Err(ClientError::Kernel { .. })` with both exact strings. Against the parent, + `run_spawn_events` ignores this field and publishes `Exited(0)`. +2. **Protocol terminal success mapper:** the same event with `error: None` + remains `Ok(0)`. This guards against treating nonzero Linux exit status as a + transport error; ordinary exit status is still a successful terminal result. +3. **Live lag failure:** subscribe while the watch contains `None`, send + `ProcessExit::EventStreamLagged { skipped: 3 }`, and assert the callback + receives exactly one `Err(ClientError::EventStreamLagged { skipped: 3 })`. + Before the fix, equivalent `on_process_exit` logic logs the error and drops + the callback. +4. **Live route closure:** send `ProcessExit::EventStreamClosed` and assert + exactly one `Err(ClientError::EventStreamClosed { context: "process exit" })`. +5. **Unexpected watch close:** drop the sender without writing a terminal value + and assert the same typed closed result rather than no callback. +6. **Retained failure:** seed the watch with a lag/closed/protocol-failure state + before subscription, assert the callback runs synchronously, and assert the + returned subscription is a no-op. +7. **Success and unsubscribe:** preserve one success case (`Ok(7)`) and one + drop-before-terminal case proving no callback after unsubscribe. + +Use bounded `tokio::time::timeout` around asynchronous observations so a +regression fails rather than hangs. Keep the existing +`process_exit_preserves_typed_event_lag` and +`closed_process_event_stream_is_an_error_not_exit_zero` tests; they cover the +shared mapper used by both wait and callback paths. + +No real sidecar is required to prove callback delivery or the pure protocol +mapper. Existing Rust process E2E coverage proves genuine terminal codes reach +`wait_process`, while +`sidecar_bounds_captured_output_without_limiting_raw_streams` proves the same +wire rejection code/message already reaches finite `exec`. The new mapper unit +test closes the spawned-process-specific gap without adding a slow failure +fixture. + +### TypeScript unit tests: `packages/core/tests/leak-agent-os-processes.test.ts` + +Extend the existing mock `ManagedProcess.wait()` harness: + +1. In the successful early/late cases, assert handlers receive + `{ ok: true, exitCode: 0/7 }`. +2. In “failed process retains a lightweight typed failure for late waiters,” + register an exit handler before `rejectWait(routeError)`. Assert it receives + exactly `{ ok: false, error: routeError }` once. Before the fix it is cleared + and never called. +3. After the failure is compacted, register a second handler and assert it is + invoked synchronously with the exact same error object. Before the fix, + `onProcessExit` throws `routeError` from the registration call. +4. Preserve assertions that `waitProcess` rejects with the same object and the + map retains only `{ state: "failed", error }`. +5. Add/retain an unsubscribe case: remove a running handler, reject the wait, + and prove the removed handler is not invoked. + +These tests validate parity with Rust without manufacturing an exit code. + +The rejected mock wait is also the client-level terminal-error test: it forwards +the exact error object produced by the native proxy for a wire +`ProcessExitedEvent.error`. Do not duplicate runtime-core's generated-frame +conversion test in AgentOs. + +### TypeScript real success coverage + +Update `packages/core/tests/spawn-flat-api.test.ts` rather than adding another +E2E. It already proves a real sidecar process exits with code 42 and that stderr +arrives before the terminal callback. Adapt it to the result union and retain +both assertions. + +### Test ownership and client-to-sidecar moves + +No Item 57 test should move to the sidecar: + +- invoking a Rust closure or JavaScript handler is necessarily client-owned; +- bounded route lag/closure and retained subscriber behavior are transport/SDK + concerns; and +- the optional terminal `RejectedResponse` is already produced and converted by + sidecar/runtime-core tests; Item 57 tests only the Rust mapper and host + callback delivery; and +- real process exit generation, output-before-terminal ordering, kill/timeout + status, and lifecycle remain covered in existing sidecar tests. + +Do not add sidecar behavior or a wire callback merely to notify host-local +listeners. + +## Dependencies, risks, and non-goals + +- **Item 22 is foundational:** it supplies typed lag/close outcomes and + fail-closed process cleanup.

The current tracker anchors +are `docs/thin-client-migration.md:104` (issue inventory), line 191 (pending +status), and line 283 (before/after/complete checklist). + +## Recommendation + +Replace the public +`SidecarTransport::request_wire_with_process_events(OwnershipScope, +RequestPayload)` method with a typed +`SidecarTransport::execute_wire(OwnershipScope, ExecuteRequest)` operation. +Keep the generated `RequestPayload::ExecuteRequest` wire variant, but make every +generic `request_wire*` entry point reject it before allocating an ID, encoding a +frame, registering a pending request, or enqueueing bytes. + +The low-level transport must remain the sole owner of Execute's atomic process +route and cancellation tombstone. A caller should not be able to opt out of that +safety behavior by choosing a more generic method that happens to accept the same +wire union. + +Use a typed `TransportError::InvalidRequest` for the rejected generic call and +map it to Rust AgentOS's existing `ClientError::InvalidArgument`. Do not change +the sidecar protocol or move cleanup into a product client. The sidecar already +owns process creation and signal handling; this item closes an unsafe transport +API path around the existing behavior. + +Priority: **P2**. Confidence: **high**. All production Rust Execute callers and +all cancellation state are in-repository, the safe path already exists, and the +wire protocol ships in lockstep. The change is an API hardening/rename plus a +pre-enqueue guard, not a new process lifecycle. + +## Cross-layer disposition + +| Layer | Exact current code | Item 58 disposition | +|---|---|---| +| Rust low-level transport | `crates/sidecar-client/src/transport.rs:629-752`, response correlation at `:839-898`, cancellation cleanup at `:394-470` | **Change.** Add the typed Execute entry point, reject Execute in all generic entry points before side effects, and make Execute mode select the existing route/tombstone behavior. | +| Rust product client | `crates/client/src/process.rs:665-710` and `crates/client/src/shell.rs:127-181` | **Change.** Pass the already-built `wire::ExecuteRequest` directly to `execute_wire`; retain all response and event handling. | +| Rust error mapping | `crates/sidecar-client/src/error.rs:3-13` and `crates/client/src/error.rs:76-82` | **Change.** Add local `InvalidRequest` and map it to existing `InvalidArgument`. | +| BARE/generated protocol | `crates/sidecar-protocol/protocol/agentos_sidecar_v1.bare:373-387,502-545,674-677,907`; compatibility tags and expected-response mapping in `crates/sidecar-protocol/src/protocol.rs:1600,1744-1791,1813,2562-2580` | **No change.** Execute must remain union tag 14 and must still expect `ProcessStarted`; only the Rust transport entry point changes. | +| Native sidecar/runtime | process start in `crates/native-sidecar/src/execution.rs:3753`, browser dispatch in `crates/native-sidecar-browser/src/wire_dispatch.rs:1907`, and their existing kill paths | **No change.** These already own process creation, the authoritative process ID, events, and signals. Moving the host-future cancellation race into them would require a new protocol lifecycle and duplicate transport correlation. | +| TypeScript runtime/client | typed process wrapper in `packages/runtime-core/src/sidecar-process.ts:1453-1517`, live request variant in `packages/runtime-core/src/request-payloads.ts:175-190` and conversion at `:471-490`, product call in `packages/core/src/sidecar/rpc-client.ts:777-804` | **No change.** TypeScript uses a different typed process wrapper; the bypass under review is the Rust transport's public union-accepting API. Keep the wire Execute variant intact. | +| Public docs/compatibility mirror | Item 58 tracker rows above; no public API docs mention the private Rust transport helper and the generated secure-exec mirror has no matching call | **Tracker evidence only.** Regenerate the mirror as a required check, but no content diff is expected. | + +The important boundary is that this item does **not** move extra behavior into +the sidecar. The sidecar already implements the Linux process behavior. It makes +the Rust transport unable to send a process-start request without also enabling +the correlation needed to observe or kill that process if the host future is +cancelled. + +## Exact transport surface and visibility + +The following inventory was rechecked repository-wide at `810ce567c333`. These +are the only public/private signatures that select Execute's transport +lifecycle: + +| Visibility | Current symbol and type | Current callers | Required result | +|---|---|---|---| +| `pub` | `SidecarTransport::request_wire(OwnershipScope, RequestPayload) -> Result` | Generic Rust product operations plus `CancelledProcessCleanup::drop` for `KillProcessRequest` | Retain, but reject `RequestPayload::ExecuteRequest` before any request ID or frame side effect. | +| `pub` | `SidecarTransport::request_wire_bounded(OwnershipScope, RequestPayload, usize) -> Result` | `crates/client/src/net.rs` for bounded fetch | Retain, with the same centralized Execute rejection. | +| `pub` | `SidecarTransport::request_wire_with_response_hook(OwnershipScope, RequestPayload, F) -> Result` where `F: FnOnce(&ResponsePayload) -> Result<(), TransportError> + Send + Sync + 'static` | `crates/client/src/session.rs` for atomic ACP correlation | Retain, with the same Execute rejection; a response hook must not opt into process routing. | +| `pub` | `SidecarTransport::request_wire_with_process_events(OwnershipScope, RequestPayload) -> Result<(ResponsePayload, Option), TransportError>` | Exactly `AgentOs::send_execute` and `AgentOs::open_shell` | Replace with `execute_wire(OwnershipScope, ExecuteRequest)` returning the same tuple. | +| `pub` | `SidecarTransport::next_request_id(&self) -> RequestId` | No call outside `transport.rs`; repository search finds no consumer | Make private. ID allocation is transport state, not a client operation, and the after test can still inspect `request_counter` from the inline test module. | +| private | `request_wire_with_frame_limit(OwnershipScope, RequestPayload, Option, bool, Option) -> Result` | The four public operations above | Replace the boolean with private `WireRequestMode::{Generic, Execute}` and validate the mode/payload pair before calling the now-private `next_request_id`. | +| private | `PendingWireRequest { tx, process_events, response_hook }`, `PendingWireResponse { payload, process_events, cancel_cleanup, response_hook_error }`, and `PendingRequestGuard` | Registration, reader correlation, and cancellation cleanup inside `transport.rs` only | Preserve. Derive provisional subscription/tombstone retention from `WireRequestMode::Execute`; only arm started-process cleanup when the pending record has that subscription. | +| `pub` type | `WireEventSubscription` | Rust process and shell consumers | Preserve. This is host-only routed event state the sidecar cannot consume on behalf of the Rust caller. | + +`wire::RequestPayload` must remain public and must retain its generated +`ExecuteRequest(ExecuteRequest)` variant because it is the BARE protocol union. +The smallest safe change is therefore a typed public Execute operation plus a +single private pre-encoding guard; duplicating the entire non-Execute protocol +union into another Rust enum would be larger, drift-prone, and unnecessary. + +## Original issue and exact failure + +The generated protocol must contain `ExecuteRequest`: + +- `crates/sidecar-protocol/protocol/agentos_sidecar_v1.bare:502-545` includes it + in `RequestPayload`; +- `crates/sidecar-protocol/src/protocol.rs:1744-1791` gives it union tag 14; and +- `crates/sidecar-protocol/src/protocol.rs:2562-2580` declares + `ProcessStarted` as its expected response. + +That wire representation is correct. The defect is that the public Rust +transport currently exposes two ways to send the same variant with different +cancellation semantics. + +### Unsafe generic path + +`SidecarTransport::request_wire` at +`crates/sidecar-client/src/transport.rs:628-638` accepts any +`wire::RequestPayload`, including `ExecuteRequest`, and calls +`request_wire_with_frame_limit(..., subscribe_process_events = false, ...)`. +The bounded and response-hook variants at current lines 650-682 have the same +generic payload input and also pass `false`. + +The shared helper at current lines 704-752 then: + +1. allocates a request ID and encodes the frame; +2. registers a pending oneshot with no provisional process subscription; +3. creates `PendingRequestGuard { remove_on_drop: true }`; +4. enqueues the encoded request; and +5. disarms the guard only when `subscribe_process_events` is true or a response + hook was supplied. + +If a caller sends Execute through plain `request_wire` and its future is +cancelled after step 4, `PendingRequestGuard::drop` at current lines 1038-1067 +removes the pending entry. The sidecar may already have committed process +creation. When `ProcessStartedResponse` arrives, the reader finds no entry at +current lines 839-898, logs “response for unknown request id,” and cannot learn +the process ID needed for cleanup. The process has neither an event route nor a +kill tombstone and can continue as an orphan from the caller's perspective. + +### Existing safe path + +`request_wire_with_process_events` at current lines 684-702 performs a runtime +variant check, then calls the same helper with `subscribe_process_events = true`. +That changes the lifecycle in three load-bearing ways: + +- `WireEventLog::subscribe_provisional()` is stored in the pending request; +- after successful enqueue, the pending guard is disarmed so cancellation + retains a bounded tombstone; and +- the reader binds the provisional subscription to exact + `(full ownership, process_id)` before waking the waiter. + +When a `ProcessStartedResponse` is decoded, the reader also arms +`CancelledProcessCleanup` at current lines 855-880. If the request waiter has +already been cancelled, sending the response through the oneshot fails, the +delivered value drops, and `CancelledProcessCleanup::drop` at current lines +424-470 asynchronously sends sidecar-owned `KillProcess(SIGKILL)` for the exact +process. If the waiter receives the response normally, the helper disarms that +cleanup at lines 742-751 and returns the bound event subscription. + +The safe behavior is already covered in pieces, but the public safe method still +takes the entire request union and generic methods do not prohibit Execute. API +shape, rather than convention, should select this lifecycle. + +## Current production call inventory + +Repository-wide search finds exactly two product uses of the specialized path: + +| Caller | Current location | Use | +|---|---|---| +| `AgentOs::send_execute` | `crates/client/src/process.rs:665-710` | All Rust `exec`, `exec_argv`, and `spawn` starts. | +| `AgentOs::open_shell` | `crates/client/src/shell.rs:127-181` | PTY-backed shell start. | + +Both already use the safe method. No production Rust source sends +`RequestPayload::ExecuteRequest` through plain `request_wire`, +`request_wire_bounded`, or `request_wire_with_response_hook` today. That is why +the current product paths are correct and the issue remains an exposed low-level +API footgun. + +Native sidecar code that constructs an `ExecuteRequest` internally for cron or +dispatch is not a client transport caller and is outside this item. + +## Exact production edits + +### `crates/sidecar-client/src/error.rs` + +Add a typed transport misuse variant: + +```rust +/// A request selected a transport operation that cannot provide its required routing semantics. +#[error("invalid transport request: {0}")] +InvalidRequest(String), +``` + +This error is produced before anything reaches the sidecar. Do not report it as +`TransportError::Sidecar`; that would falsely attribute a local API misuse to the +sidecar. + +### `crates/client/src/error.rs` + +Extend `impl From for ClientError` at current lines 68-75: + +```rust +TransportError::InvalidRequest(message) => ClientError::InvalidArgument(message), +``` + +No normal AgentOS product call should hit this branch after its two Execute +callers move to the typed operation. The mapping keeps the conversion exhaustive +and preserves the correct local-invalid-input classification for any future +internal misuse. + +### `crates/sidecar-client/src/transport.rs` + +#### Hide request-ID allocation + +Change `pub fn next_request_id` to private `fn next_request_id`. Repository-wide +search finds no external caller, and callers must never allocate transport IDs +independently of pending registration. The inline transport tests retain access +to both the method and `request_counter` through Rust module privacy. + +#### Add a private request mode + +Replace the ambiguous `subscribe_process_events: bool` parameter with a private, +two-case mode, for example: + +```rust +#[derive(Clone, Copy, Debug, PartialEq, Eq)] +enum WireRequestMode { + Generic, + Execute, +} +``` + +The three generic public operations pass `WireRequestMode::Generic`. +`execute_wire` passes `WireRequestMode::Execute`. Keep response-hook retention as +the separate existing concern; a generic response hook must not make Execute +legal. + +#### Reject Execute centrally before encoding + +At the very start of `request_wire_with_frame_limit`, before +`next_request_id()`, validate the payload/mode pair: + +```rust +let is_execute = matches!(&payload, wire::RequestPayload::ExecuteRequest(_)); +match (mode, is_execute) { + (WireRequestMode::Generic, true) => { + return Err(TransportError::InvalidRequest(String::from( + "ExecuteRequest must use SidecarTransport::execute_wire", + ))); + } + (WireRequestMode::Execute, false) => { + return Err(TransportError::InvalidRequest(String::from( + "SidecarTransport::execute_wire requires ExecuteRequest", + ))); + } + _ => {} +} +``` + +The second arm is an internal invariant guard; the typed public method makes it +unreachable to normal callers. Keeping the check centralized means +`request_wire`, `request_wire_bounded`, and +`request_wire_with_response_hook` cannot diverge. + +Derive provisional process-event subscription and post-enqueue tombstone +retention from `mode == WireRequestMode::Execute`, replacing the current boolean +checks. Preserve response-hook tombstones for non-Execute resource-establishing +extension requests. + +Do not place the rejection after encoding or enqueue. The after test must prove +that invalid generic Execute neither consumes a request ID nor writes a frame. + +#### Replace the public specialized method + +Delete `request_wire_with_process_events`. Add: + +```rust +/// Issue Execute while atomically binding its process event route and retaining +/// post-enqueue cancellation cleanup until ProcessStarted is decoded. +pub async fn execute_wire( + &self, + ownership: wire::OwnershipScope, + request: wire::ExecuteRequest, +) -> Result< + (wire::ResponsePayload, Option), + TransportError, +> { + let response = self + .request_wire_with_frame_limit( + ownership, + wire::RequestPayload::ExecuteRequest(request), + None, + WireRequestMode::Execute, + None, + ) + .await?; + Ok((response.payload, response.process_events)) +} +``` + +Keeping `Option` preserves the current rejected-response +shape: a `RejectedResponse` has no bound process route, while a valid +`ProcessStartedResponse` must return one and the product client already checks +that invariant. Do not collapse sidecar `RejectedResponse { code, message }` +into a generic transport error; `crates/client` maps it to +`ClientError::Kernel` with the original code. + +Add rustdoc stating that all generic request methods reject Execute. A small +`compile_fail` example should show that `execute_wire` accepts `ExecuteRequest`, +not `RequestPayload::ExecuteRequest(request)`. Do not claim that the protocol's +generic request union cannot represent Execute: it must. Its remaining generic +transport entry points exclude Execute with the tested pre-enqueue runtime +guard. + +#### Tie cleanup to the Execute pending record + +In the response arm at current lines 839-890, arm +`CancelledProcessCleanup` only when the pending request has a provisional +process subscription and the response is `ProcessStartedResponse`. After the +generic guard, a valid started response should already have that subscription; +making the relationship explicit prevents a mismatched generic response from +manufacturing Execute cleanup semantics. + +Keep all existing bounded-log, exact-ownership route binding, +`CancelledProcessCleanup`, silence-watchdog, response-hook, writer-priority, and +pending-limit code. + +### `crates/client/src/process.rs` + +At `AgentOs::send_execute` (current lines 665-710), replace: + +```rust +.request_wire_with_process_events( + ownership, + wire::RequestPayload::ExecuteRequest(build_process_execute_request(...)), +) +``` + +with: + +```rust +.execute_wire(ownership, build_process_execute_request(...)) +``` + +Keep `build_process_execute_request`, response/rejection mapping, and the +requirement that a successful start contains a bound event subscription. Do not +fold Item 59's post-start stdin/EOF failure handling into this revision. + +### `crates/client/src/shell.rs` + +At `AgentOs::open_shell` (current lines 127-181), keep building the same typed +`wire::ExecuteRequest`, then replace the union-wrapped specialized call with: + +```rust +let (response, events) = self + .transport() + .execute_wire(ownership.clone(), execute) + .await?; +``` + +Keep PTY options, response validation, event pumping, route-failure cleanup, and +shell registry behavior unchanged. + +## Exact test work + +All transport regression tests belong in the existing inline test module in +`crates/sidecar-client/src/transport.rs`. No new fake transport layer is needed. + +### Before test: reproduce the bypass + +Before adding the generic guard, add a temporary test named approximately +`generic_execute_cancelled_after_enqueue_loses_cleanup_route`: + +1. construct an `Arc` with a visible `request_writer_rx`, as + the existing cancellation tests do; +2. spawn `request_wire(vm_ownership, + RequestPayload::ExecuteRequest(test_execute_request()))`; +3. receive and decode the outbound Execute frame, proving enqueue completed; +4. abort the request task and assert the pending count becomes zero; +5. deliver a matching `ProcessStartedResponse` through `handle_wire_frame`; and +6. assert no `KillProcessRequest` appears on `request_writer_rx` within a short + bounded timeout. + +That test passes on the vulnerable parent and is the tracker checkbox's concrete +before evidence: cancellation removed the only correlation record after the +sidecar could have committed process creation. Record its command/result in the +tracker, then replace it with the after regression; do not commit a test that +endorses the orphaning behavior. + +### After test: generic paths reject before enqueue + +Add a committed test named approximately +`generic_request_paths_reject_execute_before_enqueue`. Exercise all three public +generic operations with fresh Execute payloads: + +- `request_wire`; +- `request_wire_bounded`; and +- `request_wire_with_response_hook`. + +For each, assert: + +- the result is `TransportError::InvalidRequest` naming `execute_wire`; +- no outbound frame is available; +- `pending_request_count` remains zero; +- the response hook is not called; and +- the request counter is unchanged, proving rejection occurred before ID + allocation/encoding. + +The generated `RequestPayload` still being able to represent Execute is not a +failure—the protocol requires it. The contract is that no generic transport +operation can successfully encode or enqueue it. + +### Exercise the real specialized API in cancellation tests + +The current +`cancelled_execute_retains_tombstone_and_kills_started_process` test at lines +2056-2141 manually calls `register_pending` and constructs a disarmed guard. It +proves the pieces but not that the public method selects them. Rewrite its +post-enqueue case to: + +1. spawn `execute_wire(ownership, test_execute_request())`; +2. receive/decode its Execute frame and capture the allocated request ID; +3. abort the task after enqueue and assert one pending tombstone remains; +4. deliver `ProcessStartedResponse` for that request ID; +5. assert an exact-owner `KillProcessRequest { signal: "SIGKILL" }` is emitted; +6. deliver `ProcessKilledResponse`; and +7. assert the pending map is empty. + +Retain deterministic coverage for cancellation after a start response is +buffered but before the waiter consumes it. The current manual oneshot test is a +valid way to force that timing without a scheduler race; rename/split it if +needed rather than losing the case. + +Update `execute_cancelled_before_enqueue_removes_pending_slot` at current lines +2143-2199 to call `execute_wire` with a typed request. Keep its full writer queue +and zero-pending assertion. Also retain +`process_route_is_bound_before_started_response_is_observed` and the response +hook cancellation test unchanged except for any helper renames. + +### Compile/API coverage + +The two production call sites compiling with `ExecuteRequest` provide positive +typed API coverage. Add a rustdoc `compile_fail` example beside `execute_wire` +that attempts to pass `RequestPayload::ExecuteRequest(request)` to the typed +method (or calls the removed `request_wire_with_process_events` API). Run doctests +explicitly. Combined with the pre-enqueue generic rejection test, this proves: + +- the only process-routing operation accepts a typed `ExecuteRequest`; +- the old union-accepting specialized API is gone; and +- the remaining generic union-accepting APIs cannot transmit Execute, although + the wire union correctly remains able to represent it at compile time. + +Do not add `trybuild` solely for this item; rustdoc plus the runtime transport +test covers the public shape without a new dependency or lockfile churn. + +## Before and after checklist + +### Before behavior + +- [ ] The temporary generic-path cancellation test enqueues Execute, aborts its + waiter, observes the pending entry disappear, and receives no cleanup kill + after `ProcessStartedResponse`. +- [ ] Repository search confirms production `crates/client` callers happen to + use `request_wire_with_process_events`, showing safety currently depends on + convention rather than the generic API. +- [ ] Baseline `cargo test -p agentos-sidecar-client --lib` passes the existing + 28 transport tests, including specialized before-enqueue, route-binding, and + cancellation cleanup cases. + +Baseline evidence recorded during this research at `ea02cbc40b22`: + +| Command | Result | +|---|---| +| `cargo test -p agentos-sidecar-client --lib` | **pass: 28 passed, 0 failed** | +| `cargo test -p agentos-sidecar-client --test wire_protocol` | **pass: 3 passed, 0 failed** | +| `cargo test -p agentos-client --lib` | **pass: 69 passed, 0 failed** | + +### After behavior + +- [ ] All generic `request_wire*` variants return + `TransportError::InvalidRequest` for Execute before ID allocation, pending + registration, encoding, enqueue, or hook invocation. +- [ ] `execute_wire` accepts `wire::ExecuteRequest` directly; the old + union-accepting specialized method is absent and its compile-fail doctest + passes. +- [ ] Post-enqueue cancellation through the real `execute_wire` method retains + one bounded tombstone, binds the authoritative process ID, and sends + `SIGKILL` if the waiter is gone. +- [ ] Before-enqueue cancellation removes its pending slot, and buffered-start + cancellation still triggers cleanup. +- [ ] `AgentOs::send_execute` and `AgentOs::open_shell` compile and retain their + current response/event behavior. +- [ ] Rust process and shell E2Es remain green in the explicit expensive phase. +- [ ] The generated secure-exec compatibility mirror is regenerated; because it + is a pure Rust re-export shim, no content change is expected. +- [ ] Item 58 is marked `done` only after evidence is recorded in the tracker. + +Focused validation commands: + +```sh +cargo fmt --all -- --check +cargo test -p agentos-sidecar-client --lib +cargo test -p agentos-sidecar-client --doc +cargo test -p agentos-sidecar-client --test wire_protocol +cargo test -p agentos-client --lib +cargo check -p agentos-client +cargo check --workspace +node scripts/generate-secure-exec-mirror.mjs +git diff --check +``` + +Run these real-sidecar suites in the explicit expensive phase with the required +sidecar/software assets built: + +```sh +cargo test -p agentos-client --test process_e2e +cargo test -p agentos-client --test shell_e2e +``` + +## Client-to-sidecar test migration + +None is appropriate for Item 58.

This note does not modify production +code, tests, or the Item 59 tracker status. + +## Recommendation + +Add `initialStdin: optional` and +`closeStdinAfterInitial: optional` to the existing wire +`ExecuteRequest`. Define the sidecar contract as: + +- if `initialStdin` is present, write those bytes after process creation; +- if `closeStdinAfterInitial` is explicitly `true`, deliver EOF after the + optional initial write; +- do not return `ProcessStarted` until both requested operations succeed; and +- if either operation fails after launch, force-abort the process in the sidecar + and return the original stdin-stage rejection. + +TypeScript and Rust finite `exec` then send one `Execute` request containing the +caller's optional stdin and `closeStdinAfterInitial: true`. They delete their +subsequent `WriteStdin` and `CloseStdin` requests. Raw `spawn` and shell retain +the separate streaming write/close protocol because they return a live handle +and necessarily accept input after start. + +This is preferable to adding client-side cleanup. The sidecar is the only layer +that can make process creation, initial input, EOF, and rollback one lifecycle. +It also avoids exposing a process ID before finite-input initialization is known +to be valid. + +`closeStdinAfterInitial: true` is not a client-authored default. It is the +explicit wire representation of the finite `exec` API's existing promise to +deliver EOF. It must be separate from `keepStdinOpen`: that existing field +controls guest-runtime stdin liveness (`AGENTOS_KEEP_STDIN_OPEN`) and does not +currently close the kernel stdin endpoint. Normal spawn continues to preserve +`keepStdinOpen` omission, `true`, and `false` exactly as the caller supplied +them. Neither new field is defaulted by either client or the sidecar. + +Priority: **P1**. Confidence: **high**. The unsafe sequences and all native and +browser process-control implementations are in this repository. The main risk +is protocol-wide mechanical fallout from adding one generated struct field, not +uncertainty about ownership or behavior. + +Tracker anchors in the current tree: + +- issue: `docs/thin-client-migration.md:105`; +- status: `docs/thin-client-migration.md:192`; and +- before/after/completion checklist: `docs/thin-client-migration.md:284`. + +## Original issue and exact failure + +### TypeScript + +`NativeSidecarKernelProxy.exec` and `execArgv` at +`packages/core/src/sidecar/rpc-client.ts:394-449` currently do this: + +```ts +const proc = await this.spawn(...); // Execute has succeeded +if (options?.stdin !== undefined) { + await proc.writeStdin(options.stdin); // a second request +} +await proc.closeStdin(); // a third request +return await proc[processCompletion]; +``` + +`spawn` installs the returned process into `trackedProcesses` and +`trackedProcessesById` at current lines 454-529 and 777-804. If either stdin +request rejects, finite `exec` returns the rejection without a kill and without +waiting for the process. The internal event pump still knows the entry, but the +caller never received the `ManagedProcess` handle, so it cannot supervise or +terminate the live process. It remains until it exits independently, the VM is +disposed, or another lifecycle path happens to clean it up. + +The existing tests in +`packages/core/tests/process-event-ordering.test.ts:141-196` already inject a +write rejection and an EOF rejection. They prove the original error propagates, +but they currently push a synthetic exit to finish cleanup and never require a +kill. Those tests are the best pre-change characterization seam. + +### Rust + +`AgentOs::exec_request` at `crates/client/src/process.rs:202-294` calls +`send_execute`, receives `(ProcessStartedResponse, WireEventSubscription)`, then +issues an optional `WriteStdinRequest` at current lines 231-250 and an +unconditional `CloseStdinRequest` at lines 251-266. + +Any transport failure, `RejectedResponse`, or unexpected response in those two +blocks returns before `collect_exec_events`. The local `process_id` is lost and +the event subscription is dropped. Unlike `spawn`, finite Rust exec never puts +this process in `AgentOsInner.processes`, so the caller has neither a handle nor +a registry entry from which to kill it. + +The later event-stream-lag branch at lines 279-286 correctly calls +`abort_wire_process_after_route_failure`, but that protection is unreachable +for the earlier stdin-control failures. + +### Why the protocol permits the gap + +`ExecuteRequest` in +`crates/sidecar-protocol/protocol/agentos_sidecar_v1.bare:373-387` has launch, +PTY, stdin-lifetime, timeout, and capture fields, but no initial input. Initial +input and EOF therefore require the separate request types at current lines +389-402. + +The native sidecar implements the operations independently in +`crates/native-sidecar/src/execution.rs:3751-4157`, `4209-4250`, and +`4252-4280`. The browser sidecar does the same in +`crates/native-sidecar-browser/src/wire_dispatch.rs:1907-2097`, `2099-2130`, +and `2132-2160`. Neither adapter can currently know that the later write and EOF +belong to a finite-exec transaction whose failed setup must abort the process. + +The existing sidecar/process protocol already carries the authoritative +terminal result. `ProcessExitedEvent` at +`crates/sidecar-protocol/protocol/agentos_sidecar_v1.bare:969-975` includes the +process ID, real `i32` exit code, optional captured output, and optional typed +rejection. Item 59 does not alter that event. It only prevents an initialization +failure from being reported as a successful `ProcessStarted` followed by an +unsupervised process. + +## Boundary and documentation audit + +This is sidecar-owned lifecycle behavior, not a new client abstraction. The +clients are allowed to encode and forward explicit `ExecOptions.stdin`; they +must not coordinate multiple state-changing requests or own rollback policy. +The sidecar already owns process registration, stdin endpoints, signals, +terminal events, and reaping, so it is the only layer that can guarantee that a +failed finite-input start is never exposed as a usable process. + +No public TypeScript or Rust API changes: + +- `ExecOptions.stdin` remains the caller input; +- `exec`/`execArgv` and `exec`/`exec_argv` retain their current result types; +- `spawn`, `writeProcessStdin`, `closeProcessStdin`, Rust process streams, and + shell streaming controls retain their current live-handle contracts; and +- no new client default, retry, timeout, or process registry is introduced. + +The user-facing docs scan found only existing semantic descriptions: + +- `packages/core/README.md:83` describes `exec` at API level; +- `website/src/content/docs/docs/processes.mdx:7` describes finite exec versus + streaming spawn; +- `website/src/content/docs/docs/architecture/processes.mdx:49-54` describes + kernel stdin/EOF; and +- the runtime examples use the unchanged public methods. + +Those claims remain correct, so Item 59 should not churn website or example +docs. Document the atomic initialization contract in comments beside the new +BARE field and sidecar helper, and update only the migration tracker after tests. + +## Exact replacement contract + +Extend the schema, preferably adjacent to `keepStdinOpen`: + +```bare +type ExecuteRequest struct { + # existing fields ... + initialStdin: optional + closeStdinAfterInitial: optional + keepStdinOpen: optional + timeoutMs: optional + captureOutput: optional +} +``` + +The sidecar operation order must be exactly: + +1. validate and resolve the Execute request; +2. create and register the active process internally; +3. write `initialStdin` when present, including preserving explicit empty input; +4. close stdin when `closeStdinAfterInitial == Some(true)`; +5. only then emit lifecycle busy state and return `ProcessStarted`; +6. on step 3 or 4 failure, issue `SIGKILL`/browser abort, retain the process in + sidecar supervision until it is reaped, log any cleanup failure with the + process ID, and return the original setup error instead of cleanup's error. + +The native lifecycle emission in step 5 is itself fallible. Treat it as part of +the same pre-response transaction: if `emit_lifecycle(Busy)` fails after the +process was inserted, abort the process and preserve the lifecycle error as the +primary rejection. The current code already has a broader post-launch gap at +this exact line; moving stdin into Execute must not leave a rejected Execute +owning a process that no client can name. This is cleanup of the touched +transaction boundary, not client policy or a new lifecycle state machine. + +Item 58's Execute transport route remains active throughout these steps. Early +output/terminal events may exist before the delayed `ProcessStarted` response; +the provisional route must preserve them and bind them to the authoritative +process ID on success. On an Execute rejection it must discard the provisional +route without manufacturing a started process. Do not add a second client event +buffer or bypass Item 58's typed `execute_wire` entry point. + +Omitted or `false` `closeStdinAfterInitial` does not close stdin. Existing +`keepStdinOpen` behavior remains unchanged, preserving streaming spawn and PTY +behavior. No global stdin default should be added to `apply_execute_defaults`. + +The initial bytes remain bounded by the existing request frame limit. They now +share that frame with launch metadata, so the theoretical maximum input is +smaller by the encoded Execute-field overhead than today's standalone +`WriteStdinRequest`. No exact standalone-stdin capacity is public, and an +oversized atomic request fails before launch, which is safe. Record this as a +bounded compatibility risk; do not restore client chunking or a multi-request +transaction to recover a few metadata bytes. + +## Exact production edits + +### Protocol and generated TypeScript + +1. In + `crates/sidecar-protocol/protocol/agentos_sidecar_v1.bare:373-387`, add + `initialStdin: optional` and + `closeStdinAfterInitial: optional` to `ExecuteRequest`, with comments + that the bytes are written and the optional close is performed before + `ProcessStarted`; both participate in fail-closed initialization. Do not + reinterpret `keepStdinOpen`. +2. Regenerate `packages/runtime-core/src/generated-protocol.ts` with + `pnpm --dir packages/build-tools build:protocol`; do not hand-edit it. +3. In `packages/runtime-core/src/request-payloads.ts:175-190`, add + `initial_stdin?: Uint8Array` and `close_stdin_after_initial?: boolean` to the + live Execute payload. +4. In the Execute conversion at current lines 473-506, map the bytes with + `toExactArrayBuffer(payload.initial_stdin)` and the boolean without a truthy + check, preserving omission as `null` for both. + +Rust generated wire code is produced from the schema at build time. Adding the +fields makes every Rust `ExecuteRequest { ... }` literal require +`initial_stdin: None` and `close_stdin_after_initial: None` unless it is a +finite-exec construction. The mechanical compile-fix inventory is currently: + +- `crates/agentos-sidecar/src/acp_extension.rs` +- `crates/client/src/process.rs` +- `crates/client/src/shell.rs` +- `crates/native-sidecar-browser/src/wire_dispatch.rs` +- `crates/native-sidecar-browser/tests/wire_dispatch.rs` +- `crates/native-sidecar-core/src/execution_defaults.rs` +- `crates/native-sidecar/src/service.rs` +- `crates/native-sidecar/tests/{extension,filesystem,python,security_hardening,service,signal,stdio_binary}.rs` +- `crates/native-sidecar/tests/support/mod.rs` +- `crates/sidecar-client/src/transport.rs` + +Keep those edits mechanical. Do not use the new fields for cron, ACP, shell, +spawn, or internal sidecar launches as part of Item 59. + +Extend `crates/native-sidecar-core/src/execution_defaults.rs` with one focused +assertion that `apply_execute_defaults` leaves both new fields unchanged for PTY +and non-PTY requests. It must neither synthesize initial bytes nor turn an +omitted close flag into `false`/`true`. + +### TypeScript transport serializer + +In `packages/runtime-core/src/sidecar-process.ts:1453-1517`: + +- add `initialStdin?: string | Uint8Array` to `SidecarProcess.execute` options; +- add `closeStdinAfterInitial?: boolean`, preserving false and omission; +- encode strings as UTF-8 exactly like current `writeStdin`, serialize the + result as `initial_stdin`, and preserve omission; and +- leave `writeStdin` and `closeStdin` intact for live spawn/shell handles. + +Extend +`packages/runtime-core/tests/request-payloads.test.ts:350-384` and +`packages/runtime-core/tests/sidecar-process.test.ts:275-310` to prove exact +text/binary byte forwarding, explicit empty input, explicit `false`, and +omission for `closeStdinAfterInitial`, while proving `keepStdinOpen` is +unchanged. + +### TypeScript core client + +In `packages/core/src/sidecar/rpc-client.ts`: + +1. Extend the private `TrackedProcessEntry` near current lines 163-182 with an + optional `initialStdin: string | Uint8Array` and + `closeStdinAfterInitial: boolean | undefined`. These are explicit request + data, not policy. Encode strings once at the runtime-core request serializer, + using the same UTF-8 behavior as current `writeStdin` at + `packages/runtime-core/src/sidecar-process.ts:1519-1544`. +2. Extend the existing private internal spawn-options seam near lines 454-469 + with `initialStdin?` and `closeStdinAfterInitial?`. No separate finite-input + marker is needed: the new close field represents finite EOF even when stdin + itself was omitted. Do not put initial stdin back on public + `KernelSpawnOptions`; Item 43 removes inert raw-spawn stdin. +3. Have `exec` and `execArgv` pass their explicit `options.stdin` as + `initialStdin` and explicitly pass `closeStdinAfterInitial: true` for this + finite operation. Runtime-core performs the one UTF-8 encoding at the wire + seam. Do not set or reinterpret `streamStdin`/`keepStdinOpen`. +4. Delete both client-side `proc.writeStdin(...)` and `proc.closeStdin()` blocks. + They should start the tracked process once and then await only + `processCompletion`. +5. In `startTrackedProcess` at current lines 777-804, forward + `entry.initialStdin` and `entry.closeStdinAfterInitial` when present. + +An equally small private `startFiniteProcess` helper is acceptable if Item 43 +has already removed the internal cast. Do not add a public finite-input builder, +retry state machine, or client kill fallback. An Execute rejection happens +before the entry is inserted into either tracking map, while a successful +Execute is tracked and observed exactly as today. + +Public `AgentOs.exec`/`execArgv` in +`packages/core/src/agent-os.ts:1607-1638` already only forward to the kernel +proxy and need no behavioral logic. + +### Rust client + +In `crates/client/src/process.rs`: + +1. Convert `options.stdin.take()` with the existing `stdin_to_bytes` before + `send_execute` in `exec_request` at current lines 202-228. +2. Extend `send_execute` and `build_process_execute_request` at current lines + 698-743 and 890-915 with `initial_stdin: Option>` and + `close_stdin_after_initial: Option`. +3. For finite `exec_request`, pass the converted bytes and + `close_stdin_after_initial: Some(true)`. Preserve the existing + `keep_stdin_open` argument independently. +4. Delete the post-start `WriteStdinRequest` and `CloseStdinRequest` blocks at + current lines 231-266. +5. Pass both new fields as `None` from raw `spawn` and from `open_shell` in + `crates/client/src/shell.rs`. + +Keep `write_process_stdin`, `close_process_stdin`, and shell write/close methods. +They are live-handle transport operations and are not the duplicated finite +policy this item removes. + +After Item 58, `send_execute` should use the typed Execute transport operation. +The new field does not change the atomic event-route requirement or introduce a +second transport path. + +### Native sidecar + +In `crates/native-sidecar/src/execution.rs`: + +1. Extract the process mutation portions of current `write_stdin` and + `close_stdin` into private helpers that accept `&mut VmState` plus + `process_id`. The existing wire handlers should call the same helpers, so + atomic Execute and streaming controls cannot diverge on JavaScript PTY, + kernel-fd, Python, WASM, or tool behavior. +2. Add an `initialize_execute_stdin` helper that performs optional write then + optional close against the newly inserted active process. +3. Call it in both Execute success branches: + - the projected-tool branch after insertion around current lines 3840-3868; + - the normal runtime branch after insertion around current lines 4129-4140. +4. Move lifecycle-busy emission and `ProcessStarted` construction after this + initialization succeeds. +5. On an initialization **or lifecycle-busy emission** failure, release the + mutable VM borrow, call + `kill_process_internal(vm_id, process_id, "SIGKILL")` at current lines + 4645-4652, log a cleanup failure with both errors if it occurs, and return the + original write/close/lifecycle `SidecarError`. + +Do not duplicate the code in `ActiveExecution::write_stdin` / +`close_stdin` (current lines 3246-3278) or the kernel helpers at current lines +19458-19535. Those are already the runtime-specific source of truth. + +The projected-tool path currently treats write and close as successful no-ops. +Preserve that behavior; changing tool stdin semantics is outside this item. + +### Browser sidecar + +In `crates/native-sidecar-browser/src/wire_dispatch.rs:1907-2097`: + +1. After `start_execution_with_options` succeeds, use the returned execution ID + to call `BrowserSidecar::write_stdin` for `initial_stdin`, then + `BrowserSidecar::close_stdin` when + `close_stdin_after_initial == Some(true)`. +2. Perform this before inserting `ExecutionRecord` and `process_executions` at + current lines 2082-2095 and before returning `ProcessStarted`. +3. If either operation fails, call + `BrowserSidecar::abort_execution(vm_id, execution_id)` from + `crates/native-sidecar-browser/src/service.rs:2551-2580`. That method already + force-kills and releases the browser worker/kernel execution. +4. Return `write_stdin_failed` or `close_stdin_failed` with the original primary + message. Log abort/release errors separately; do not replace the primary + rejection or install wire process maps for a failed start. + +The separate browser wire `write_stdin`, `close_stdin`, and `kill_process` +handlers at `wire_dispatch.rs:2099-2190` remain for streaming processes. + +## Before and after tests + +### Before validation + +TypeScript can characterize the current bug directly in +`packages/core/tests/process-event-ordering.test.ts` by extending the existing +two rejection tests: + +- after a write rejection, assert `killProcess` and `closeStdin` were not called + and `__trackingSizesForTest()` still reports one live tracked entry; +- after an EOF rejection, assert `killProcess` was not called and the same entry + remains; and +- retain `rejects.toBe(writeError/closeError)` to prove the primary error. + +These assertions pass against the pre-change code and explicitly demonstrate +why propagation alone is insufficient. Record their pre-change command/result +in the Item 59 tracker before replacing them. + +Rust has no injectable `AgentOs` transport seam today. For the pre-change +checklist, use a temporary test-only extraction of the current post-start stdin +sequence in `crates/client/src/process.rs`: supply closures that return a +successful Execute/process ID followed by a write or close rejection, then +assert the function returns without invoking a kill closure and drops the event +receiver. This temporary characterization helper should not survive the final +diff; retaining a client process-orchestration abstraction would conflict with +the fix. Record both cases in the tracker. + +### Retained client tests after the move + +Rewrite the TypeScript ordering tests to assert: + +- `exec` and `execArgv` each send one Execute containing exact stdin bytes and + `closeStdinAfterInitial: true`, without changing `keepStdinOpen`; +- neither calls `writeStdin`, `closeStdin`, nor `killProcess`; +- an Execute `SidecarRequestRejected` is returned by identity/code/message and + no tracking entry is installed; and +- a successful ProcessStarted plus terminal event still returns the same + capture and callbacks. + +In `crates/client/src/process.rs` unit tests near the existing +`execute_request_preserves_false_true_and_omitted_stream_stdin`, assert the +finite builder contains exact text/binary bytes plus +`close_stdin_after_initial: Some(true)`, while spawn and shell contain both new +fields as `None` and preserve `keep_stdin_open` omission/explicit values. +Use focused names such as +`finite_execute_request_embeds_input_and_close` and +`streaming_execute_omits_atomic_stdin_fields`. +Keep the existing success coverage in +`crates/client/tests/process_e2e.rs:103-169`; its text, callback, and binary +stdin cases become end-to-end proof of the new atomic request from Rust. + +### Move failure ownership to sidecar tests + +Add authoritative browser tests in +`crates/native-sidecar-browser/tests/wire_dispatch.rs`: + +- `finite_execute_writes_input_and_closes_before_started` records one exact + write and one close before `ProcessStarted`; +- `finite_execute_write_failure_aborts_without_process_route` injects a bridge + write failure, expects `write_stdin_failed`, observes a kill/release, and + proves no process snapshot or wire route remains; +- `finite_execute_close_failure_aborts_without_process_route` does the same for + `close_stdin_failed`; and +- both failure tests assert the injected primary message survives even if an + abort-cleanup error is also injected. + +The shared `RecordingBridge` in `crates/bridge/tests/support.rs:43-108` already +records writes, closes, and kills and has error queues for start/kill. Add +matching bounded queues and `push_*_error` methods for stdin write and close so +these tests are deterministic. + +Add native tests beside the stdin coverage in +`crates/native-sidecar/tests/service.rs:5393-5563`: + +- a successful Execute with `initial_stdin` and + `close_stdin_after_initial: Some(true)` proves the guest reads the bytes and + then EOF without separate requests; +- a helper-level test inserts an `ActiveProcess` with an invalid kernel stdin + writer fd to force the write stage to fail, then proves `SIGKILL`/terminal + cleanup and the original `SidecarError::Kernel`; +- a second invalid-fd case omits input and forces close failure with the same + cleanup assertion; and +- a lifecycle bridge failure after successful atomic stdin initialization also + rejects, force-aborts, and remains sidecar-supervised until reaping; and +- retain the current separate `WriteStdin`/`CloseStdin` test to guard streaming + spawn behavior. + +`crates/native-sidecar/tests/service.rs` includes the production source modules +directly, so it can exercise a `pub(crate)` initialization helper and construct +the existing `ActiveProcess` fixture without exporting a production test hook. +Do not add a public failure-injection API. + +This moves the failure-injection responsibility from client orchestration tests +to the two enforcement adapters while leaving small client serialization/parity +tests in place. + +## Dependencies and risks + +- **Stack after Item 43.** Do not reintroduce public raw-spawn `stdin`; use a + private finite-exec launch field only. +- **Stack after Item 58.** Rust Execute must continue using its typed atomic + process-event route, provisional event retention, and cancellation tombstone. + Initial input does not make generic Execute safe. +- **Do not combine Item 60.** The shell CLI still queues truly streaming writes + after start and needs its own terminal queue-failure behavior. +- **Do not combine Item 63.** TypeScript request rejection is already the + exported `SidecarRequestRejected`; terminal-event error typing is separate. +- A write can partly reach the guest before failing. Cleanup must therefore be + forceful, never retry the input, and never return `ProcessStarted`. +- **Frame-bound edge:** initial bytes and launch metadata share one bounded + request. Oversize must fail with the existing typed frame-limit error before + sidecar launch; do not special-case or silently truncate input. +- The native abort may remain in `active_processes` briefly until its terminal + event is reaped. That is sidecar-owned supervision, not an orphan; tests must + poll the normal cleanup path and prove the guest is no longer live. +- Events/output may be produced before `ProcessStarted`. Existing provisional + Execute routing from Item 58 must retain and bind them in order. A rejected + atomic start must drop that provisional route without publishing a PID; do not + add a second client event buffer. +- A protocol field addition causes broad literal churn. Keep every non-finite + initializer at `None` and reject opportunistic refactors in the same revision. + +## Dedicated `jj` revision boundary + +Use one dedicated stacked revision for Item 59.

This note does not modify production +code, tests, or the Item 60 tracker status. + +Inspected and revalidated on **2026-07-14** through revision **`16a41860`**. +Tracker anchors are `docs/thin-client-migration.md:106` (issue inventory), +current line 193 (pending status), and current line 285 +(before/after/complete checklist). + +## Recommendation + +Replace both ad hoc `stdinQueue = stdinQueue.then(...)` loops in the shell CLI +with one small host-only serialized-input forwarder. The forwarder should: + +1. serialize data and EOF operations in arrival order; +2. make the first rejected operation terminal; +3. stop accepting later input; +4. invoke one supplied abort operation exactly once; and +5. expose an immediate failure signal plus a final rejection after abort, so the + command runner cannot mistake the exit caused by its own abort for success. + +Use `killProcess(pid)` as the spawned-process abort and `closeShell(shellId)` as +the PTY abort. Preserve normal EOF behavior: `closeProcessStdin(pid)` for a +spawned process and the existing `"\u0004"` terminal input for a PTY. If abort +also fails, reject with `AggregateError([inputError, abortError])` so neither +failure is discarded. + +This is legitimate client-side functionality: only the Node CLI can observe its +host `process.stdin` stream. It should contain no VM policy or emulation. The +sidecar remains authoritative for stdin delivery, EOF semantics, process IDs, +signals, terminal lifecycle, and exit status. + +Priority: **P1**. Confidence: **high**. The failure is a direct JavaScript +promise-chain consequence, both affected loops are local, and all required +sidecar termination operations already exist on both direct and actor backends. + +## Cross-layer disposition + +| Layer | Exact current code | Item 60 disposition | +|---|---|---| +| Shell CLI | `packages/shell/src/main.ts:506-560` and `:588-686` | **Change.** Replace both poisoned promise chains, distinguish host error from EOF, fail the command visibly, and invoke authoritative abort once. | +| Shared direct/actor handle | `packages/shell/src/actor-vm.ts:43-72` and adapter object at `:372-458` | **Change.** Expose and forward the existing `killProcess` and `closeShell` operations.

The EOF/error +listener queues `closeProcessStdin` at lines 530-537. If a write rejects, the +queue remains rejected. A later call performs +`rejectedPromise.then(closeOperation)`, so the close operation is never called. +The attached `catch` only prints the error; it does not repair the chain, reject +`runSpawnedCommand`, or terminate the child. Line 553 continues awaiting +`waitProcess`, which can remain pending because the child is still waiting for +EOF. + +There is a second failure in the same path: `closeChildStdin` catches and +silently discards every close error at lines 531-536. The comment says the +process may already have exited, but the code does not establish that. If the +process is still alive and the close request fails, both interactive and +`--no-interactive` execution can wait forever. The replacement must remove this +blanket catch; a real close failure is terminal unless the process wait has +already authoritatively completed. + +Concrete event sequence: + +```text +stdin data A -> queue write(A) +stdin end -> queue closeStdin after write(A) +write(A) rejects +closeStdin is skipped because its parent promise is rejected +the rejection is printed, but waitProcess never settles +``` + +### Terminal/PTY path + +`runTerminalAttempt` in `packages/shell/src/main.ts:588-686` repeats the same +pattern at lines 622-629. Normal data queues `writeShell`; EOF/error queues an +EOT byte (`"\u0004"`) through that same poisoned chain at lines 630-635. A +rejected earlier write therefore prevents EOT from reaching the terminal, and a +rejected EOT is only logged. Line 667 can wait on `waitShell` forever. + +The cleanup operation already exists. `AgentOs.closeShell` kills the +sidecar-owned shell at `packages/core/src/agent-os.ts:2017-2033`, and the actor +action forwards the same operation at +`crates/agentos-actor-plugin/src/actions/shell.rs:350-353`. The shell's common +`ShellVmHandle` simply does not expose it today. + +While tracing EOF, one adjacent Linux-behavior gap is visible: when terminal +mode is selected with `--no-interactive`, lines 651-661 attach no stdin listener +but also send no initial EOT. Docker-style `-t` without `-i` has closed stdin; +the replacement should call the forwarder's `end()` immediately in this branch +instead of leaving an interactive command waiting on an input stream the CLI +will never drive. + +## Existing termination surface + +No BARE schema, protocol generator, sidecar service, or actor contract change is +needed: + +| Operation | Direct TypeScript backend | Actor backend | +|---|---|---| +| Kill spawned process | `AgentOs.killProcess`, `packages/core/src/agent-os.ts:2123-2131` | generated `killProcess` action and `crates/agentos-actor-plugin/src/actions/process.rs:93-96` | +| Close/kill PTY shell | `AgentOs.closeShell`, `packages/core/src/agent-os.ts:2017-2033` | generated `closeShell` action and `crates/agentos-actor-plugin/src/actions/shell.rs:350-353` | + +`ShellVmHandle` at `packages/shell/src/actor-vm.ts:43-72` currently includes +write, stdin-close, and wait methods but omits `killProcess` and `closeShell`. +The actor adapter returned at lines 372-458 likewise forwards write/wait but not +those two already-supported actions. + +## Exact production edits + +### Add `packages/shell/src/serialized-input.ts` + +Add a dependency-free helper with an API approximately like this: + +```ts +export interface SerializedInputOperations { + write(data: T): Promise; + end(): Promise; + abort(): Promise; +} + +export interface SerializedInputForwarder { + write(data: T): void; + end(): void; + fail(error: unknown): void; + readonly failed: Promise; + readonly failure: Promise; +} + +export function createSerializedInputForwarder( + operations: SerializedInputOperations, +): SerializedInputForwarder; +``` + +Implementation requirements: + +- Keep one rejected queue chain. Attach observers with `void queue.catch(...)`, + but do not replace the queue with a recovered `.catch`, because already + queued operations must remain skipped after a failure. +- Track `accepting` separately. `end()` changes it to false before queuing EOF, + making EOF idempotent and preventing data after EOF. +- Route a host `process.stdin` error to `fail(error)`, not to `end()`. A host + stream failure is not EOF and its original error must remain visible. +- On the first queue rejection, set terminal state synchronously before awaiting + `abort()`. Resolve `failed` immediately, then begin abort. Multiple observers + may see the same rejection; only the first may signal or abort. +- After abort succeeds, reject `failure` with the original exact error object. + If abort rejects, use `new AggregateError([inputError, abortError], ... )`. + Attach an internal rejection observer so a naturally exited command cannot + create an unhandled rejection from a later host-input failure; the public + promise must still retain and reject with the exact final error. +- Never log inside the helper. `failure` is the one observable result, avoiding + duplicate stderr output and making unit tests deterministic. +- Do not add retries, timeouts, buffering policy, input transformation, or + process-state inference. Protocol request limits/timeouts and process + lifecycle remain sidecar-owned. + +The important implementation shape is: + +```ts +let queue = Promise.resolve(); +let accepting = true; +let terminal = false; + +const enqueue = (operation: () => Promise) => { + queue = queue.then(operation); + void queue.catch(beginFailure); +}; +``` + +`beginFailure(error)` is also the implementation of the public `fail(error)`; +it performs the one synchronous terminal-state transition, resolves `failed`, +and starts `abortAndRejectFailure`. + +The observer must not consume the rejection assigned to `queue`. For example, +if `end()` was queued synchronously after a write but before that write rejects, +the EOF operation must be skipped and `abort()` must provide the terminal +cleanup. + +### `packages/shell/src/actor-vm.ts` + +Extend `ShellVmHandle` after its current process wait method and shell wait +method: + +```ts +killProcess(pid: number): Promise; +closeShell(shellId: string): Promise; +``` + +In the actor adapter returned by `createActorShellVm`, add direct forwarding: + +```ts +async killProcess(pid) { + await handle.killProcess(pid); +}, +async closeShell(shellId) { + await handle.closeShell(shellId); +}, +``` + +`AgentOs` already structurally satisfies the enlarged interface. Do not add +fallback signal logic in `actor-vm.ts`; the actor action and sidecar already own +the exact kill request and response. + +### `packages/shell/src/main.ts`: spawned commands + +At `runSpawnedCommand` (current lines 506-560), delete `stdinQueue`, +`queueStdin`, and the swallowed `closeProcessStdin` catch. Construct the shared +forwarder after spawn: + +```ts +const stdin = createSerializedInputForwarder({ + write: (data: Uint8Array | string) => + vm.writeProcessStdin(child.pid, data), + end: () => vm.closeProcessStdin(child.pid), + abort: () => vm.killProcess(child.pid), +}); +``` + +Wire host data/end/error events to `stdin.write(data)`, `stdin.end()`, and +`stdin.fail(error)` respectively. For +`!options.interactive`, call `stdin.end()` immediately. In both branches, await +the first authoritative exit or the immediate failure signal, then await final +abort completion if input failed: + +```ts +const outcome = await Promise.race([ + vm.waitProcess(child.pid).then((exitCode) => ({ tag: "exit", exitCode }) as const), + stdin.failed.then(() => ({ tag: "inputFailed" }) as const), +]); +if (outcome.tag === "inputFailed") return await stdin.failure; +return outcome.exitCode; +``` + +This two-phase shape is load-bearing. A single race against a rejection that is +delayed until after `killProcess` completes is unsafe: the kill's process-exit +event could resolve `waitProcess` first and incorrectly return exit code 137 as +a successful CLI result. The immediate `failed` signal wins before abort begins; +`failure` then makes cleanup complete and preserves its error. Keep listener +removal and stdin pause in `finally`. + +### `packages/shell/src/main.ts`: terminal commands + +At `runTerminalAttempt` (current lines 588-686), replace `stdinQueue` and +`queueShellInput` with: + +```ts +const stdin = createSerializedInputForwarder({ + write: (data: Uint8Array | string) => vm.writeShell(shellId, data), + end: () => vm.writeShell(shellId, "\u0004"), + abort: () => vm.closeShell(shellId), +}); +``` + +Route data, EOF, and error events to `write`, `end`, and `fail` respectively. When +`options.interactive === false`, call `stdin.end()` once instead of attaching +listeners. Use the same two-phase `waitShell` versus `stdin.failed` outcome, and +await `stdin.failure` when failure starts. Only perform the existing +trailing-output flush after a successful shell exit. Keep output unsubscribe, +raw-mode restoration, resize-listener removal, and stdin cleanup in `finally`. + +Do not convert terminal EOF into a client-side signal or shell parser. The +existing EOT write is the normal terminal input operation; `closeShell` is only +the fail-closed abort after that operation cannot be delivered. + +## Exact test work + +### Before test + +In the parent revision, temporarily add a focused test in +`packages/shell/tests/serialized-input.test.ts` (or an equivalent local +reproduction beside the new helper) using the current queue algorithm: + +1. create a deferred first `write`; +2. queue that write and then queue EOF before settling it; +3. reject the write; +4. assert the stderr observer receives the error; and +5. assert the EOF spy was never called and a child-wait deferred remains + pending over a bounded microtask/short fake-timer window. + +This test documents exactly why logging is insufficient. Record it as passing +against the vulnerable parent, then replace it with the after assertions; do not +commit a test that endorses hanging behavior. + +### Committed helper tests + +Add `packages/shell/tests/serialized-input.test.ts` with deterministic fake +operations and deferred promises. It should cover: + +1. **Success ordering:** multiple writes remain serialized, EOF runs after the + last write, and data/end calls after EOF are ignored. +2. **Write rejection with EOF already queued:** EOF is skipped, `abort` runs + exactly once, `failed` resolves before abort is released, `failure` rejects + with the same error object after abort, and no later write runs. +3. **EOF rejection:** `abort` runs exactly once and `failure` rejects; the test + completes without awaiting a synthetic child exit. +4. **Abort rejection:** `failure` is an `AggregateError` whose `.errors` retain + the original input error first and cleanup error second. +5. **Repeated observation/races:** multiple queue descendants observing the + same rejection cannot abort twice or create an unhandled rejection. +6. **Abort-induced exit race:** make `abort` resolve the fake child wait before + its own promise completes; the runner still selects `inputFailed`, awaits + abort, and surfaces the input error rather than returning the killed exit + code. +7. **Host stdin error:** `fail(error)` aborts without attempting normal EOF and + retains the exact host error. + +Use deferred promises and `await Promise.resolve()` to control ordering; do not +use real child processes or long sleep-based timeouts for these unit cases. + +### CLI success regressions + +Retain the existing real CLI tests in `packages/shell/tests/cli.test.ts`: + +- `keeps stdin attached by default` at current lines 67-72 proves normal data + plus EOF still exits; +- `detaches stdin when --no-interactive is set` at lines 74-82 proves immediate + spawned-process EOF; and +- terminal command/default-shell tests at lines 84-105 preserve the PTY path. + +If a small dependency-injection seam is added around `runSpawnedCommand` and +`runTerminalAttempt`, add one fake-VM wiring test for each abort mapping +(`killProcess(pid)` and `closeShell(shellId)`). Do not export the whole CLI or +import `main.ts` from a unit test: that module executes VM creation at top level. +The pure helper tests plus compile-checked wiring are sufficient if avoiding +that larger refactor. + +### Sidecar coverage to retain + +Keep, rather than move, the existing sidecar/client lifecycle coverage: + +- `packages/core/tests/execute.test.ts:49-55` covers successful write, EOF, and + wait through the TypeScript sidecar client; +- `crates/native-sidecar/tests/kill_cleanup.rs` covers authoritative process + kill cleanup; and +- `crates/client/tests/shell_e2e.rs:119-120` covers sidecar shell close. + +Those tests prove the supplied abort operations work. They cannot reproduce the +Node CLI's poisoned promise chain and therefore do not replace the shell unit +regression. + +## Before and after checklist + +### Before behavior + +- [ ] A temporary shell test queues a rejected write and EOF using the parent + algorithm, observes the error text, and proves EOF never invokes its operation. +- [ ] The same test proves the child wait remains pending because logging does + not settle or terminate it. +- [ ] Source inventory records both independent queues and the swallowed + `closeProcessStdin` rejection. + +Research-time baseline evidence first captured at `0d180ebe3a89` and reproduced +unchanged at `16a41860`: + +| Check | Result | +|---|---| +| Standalone Node reproduction of the current `queue = queue.then(operation)` algorithm | **Pass:** a rejected write leaves a synchronously queued EOF callback uncalled. | +| `pnpm --dir packages/shell check-types` | **Environment-blocked before Item 60:** generated declarations for `@rivet-dev/agentos`, `@rivet-dev/agentos/client`, and several registry software packages had not been built.

The Rust E2E and +workspace check are explicit expensive validation; the focused shell helper +test should be the inner implementation loop. + +## Client-to-sidecar test migration + +No test should move from the shell package to the sidecar for Item 60. The bug +is specifically the host Node event/promise queue between `process.stdin` and +sidecar requests.

Item 60 is a + genuinely streaming host CLI and cannot package an unbounded interactive + terminal session into that finite request. Reuse naming/error patterns if + Item 59 lands first, but do not wait for or duplicate its protocol work. +- **Item 65 provides the cleanup-error principle.** Item 60 can use standard + `AggregateError` immediately; it should not flatten or silently log an abort + failure while waiting for the broader cleanup audit. +- **Item 66 also edits `packages/shell/src/main.ts`.** Its package-selection + probes are unrelated.

If an implementation attempts to edit actor action generation, + the BARE protocol, or native sidecar routing, it has exceeded Item 60's scope. +- No Rust client parity edit is required. The numbered defect is in the + TypeScript Node shell CLI; Rust has no equivalent host CLI stdin event loop. + +## Risks and review points + +- **A `.catch` used only for logging is not recovery.** The command runner must + observe the immediate failure signal, await the final rejected failure + promise, and start termination before it can remain stuck on + `waitProcess`/`waitShell`. +- **Do not let abort-induced exit win the race.** Signal failure before invoking + kill/close, then await abort and throw the retained error. Otherwise a fast + process-exit event can turn an input failure into an apparently normal 137. +- **Do not recover the queue and run EOF after an uncertain write.** Once a + sidecar input request fails, ordering is no longer trustworthy. Make the + stream terminal and abort the process/shell. +- **Do not swallow `closeProcessStdin`.** An already-exited process should be + recognized by the authoritative wait/sidecar behavior, not by ignoring every + close failure. +- **Abort once.** Every descendant of a rejected promise can run its rejection + observer.

Do not add Zod terminology or +effect behavior to Rust tests; the new TypeScript real-sidecar test should prove +that structural dispatch and the authoritative host parse compose. + +### Rust SDK parity + +No Rust SDK change is needed. Rust tools are authored with JSON Schema at +`crates/client/src/config.rs:187-207`, serialized unchanged at +`crates/client/src/agent_os.rs:222-243`, and host-validated before their Rust +callback at `agent_os.rs:1381-1429`. Rust cannot author or execute Zod effects. +Parity here means both clients forward the same structural wire field and both +sidecars consume it identically; Zod authoring/validation is intentionally +TypeScript-specific. + +## Verified converter behavior + +The following was verified against the installed dependencies +(`zod@4.1.11`, `zod3@3.25.x`, `zod-to-json-schema@3.25.2`): + +### Zod 4 + +Calling native `schema.toJSONSchema({ io: "input" })`: + +- converts root and nested `.transform(...)` schemas to their input shape; +- converts `.pipe(outputSchema)` to the input schema and omits output-only + constraints; +- retains representable input constraints such as `minLength`; +- omits custom refinement functions; +- does not execute a refinement or transform during conversion; and +- works recursively, so no custom Zod schema reconstruction is required. + +Calling `toJSONSchema()` without input mode still throws `Transforms cannot be +represented in JSON Schema` for transforms and describes the output side of a +pipe, which is why the option is required. + +### Zod 3 + +The existing fallback accepts: + +```ts +{ + $refStrategy: "none", + target: "jsonSchema7", + effectStrategy: "input", + pipeStrategy: "input", +} +``` + +`effectStrategy: "input"` preserves the pre-transform/refinement shape. +`pipeStrategy: "input"` is essential: the current default `"all"` emits an +`allOf` containing output constraints and would falsely claim that the sidecar +enforces post-pipe semantics. Conversion does not run user callbacks. + +Keep `zod-to-json-schema`; Item 49 must not remove it as unused because it is +still the Zod 3 compatibility converter. + +## Exact production edits + +### 1. `packages/core/src/host-tools-zod.ts` + +At lines 4-20, separate true unsupported value shapes from wrappers whose input +shape can be projected: + +```ts +const STRUCTURAL_INPUT_WRAPPER_TYPES = new Set(["pipeline", "pipe"]); + +const UNSUPPORTED_TYPES = new Set([ + "bigint", + "date", + "intersection", + "tuple", +]); +``` + +Zod 3 `effects` needs its own branch because `refinement`/`transform` are safe to +project but `preprocess` is not. + +Replace `getInnerSchema` at lines 57-62 so Zod 4's string-valued `def.type` +cannot hide a pipe's `def.in` schema: + +```ts +function getInnerSchema(schema: ZodType): ZodType | undefined { + const def = getSchemaDef(schema); + const inner = def.innerType ?? def.schema ?? def.in ?? def.type; + return inner && typeof inner === "object" + ? (inner as ZodType) + : undefined; +} +``` + +The current order is `innerType ?? schema ?? type ?? in`; on Zod 4 `def.type` +is the literal string `"pipe"`, not an inner schema. + +Delete `isCustomRefinement`, `validateChecks`, and the call to +`validateChecks` at line 186. Keep `getChecks`, because record-key validation at +lines 215-235 uses it to reject constrained record keys. + +In `validateSchema`, after the existing metadata/unsupported/discriminated-union +checks and before ordinary object recursion, add the input-wrapper handling: + +```ts +if (typeName === "effects") { + const effect = getSchemaDef(schema).effect; + const effectType = + effect && typeof effect === "object" + ?

"") + : ""; + if (effectType === "preprocess") { + throw new HostToolSchemaConversionError( + path, + "effects", + "preprocess raw input cannot be represented structurally", + ); + } + if (effectType !== "refinement" && effectType !== "transform") { + throw new HostToolSchemaConversionError( + path, + "effects", + `unsupported Zod effect kind: ${effectType || "unknown"}`, + ); + } + const inner = getInnerSchema(schema); + if (!inner) { + throw new HostToolSchemaConversionError( + path, + "effects", + "effect schema is missing its input schema", + ); + } + validateSchema(inner, path); + return; +} + +if (STRUCTURAL_INPUT_WRAPPER_TYPES.has(typeName)) { + const inner = getInnerSchema(schema); + if (!inner) { + throw new HostToolSchemaConversionError( + path, + displayTypeName(typeName), + "pipe schema is missing its input schema", + ); + } + validateSchema(inner, path); + return; +} +``` + +Do not add these wrappers to the existing generic transparent set without the +preprocess distinction. Continue rejecting discriminated unions, tuples, +intersections, dates, bigint, metadata-generated refs, constrained record keys, +and any other shape the sidecar CLI cannot project. + +At `generateJsonSchema` (`host-tools-zod.ts:343-363`), request the input side in +both compatibility paths: + +```ts +const nativeJsonSchema = ( + schema as ZodType & { + toJSONSchema?: (options?: { io?: "input" | "output" }) => unknown; + } +).toJSONSchema?.({ io: "input" }); +``` + +and: + +```ts +const generated = zodV3ToJsonSchema(schema as never, { + $refStrategy: "none", + target: "jsonSchema7", + effectStrategy: "input", + pipeStrategy: "input", +}); +``` + +Keep `findUnsupportedGeneratedKeyword` and `sanitizeJsonSchema`. Add a short +comment above `zodToJsonSchema` saying its result is a sidecar-facing structural +input schema, not the authoritative validator. + +### 2. `packages/core/src/agent-os.ts` + +At line 1035, make the one authoritative parse async-capable: + +```ts +const parsed = await tool.inputSchema.safeParseAsync(payload.input); +``` + +Leave the existing `!parsed.success` response and `execute(parsed.data)` logic in +place. Do not parse in `toolToSidecarDefinition`, the serializer, or another +helper. The conversion step must never execute caller code. + +Keep parsing before the `try` that maps execution failures. An unexpected throw +from a malformed schema should reach the request/transport error path instead of +being mislabeled as a normal validation failure. + +### 3. Public documentation + +The behavior is user-visible. Add this boundary after +`website/src/content/docs/docs/bindings.mdx:33`: + +```md +Refinements and transforms run only on the host. AgentOS forwards their +input-side structural shape to the VM to build CLI flags, then runs the complete +Zod schema exactly once before `execute`. Async refinements and transforms are +supported; validation errors are returned to the calling command. +``` + +No example source needs to change. `examples/bindings/README.md:12` already +correctly says that Zod validates before the host handler executes. + +## Exact tests to change + +### Converter unit: `packages/core/tests/host-tools-zod.test.ts` + +Remove only the custom-refinement case at lines 192-198 from “rejects other +lossy Zod constructs”. Retain every truly unsupported case. + +Add parallel Zod 4 and Zod 3 tests containing: + +- a constrained string with a custom refinement and transform; +- an object/root custom refinement; +- a pipe whose output adds a constraint absent from its input; and +- counters proving conversion does not execute effects. + +Assert the generated JSON Schema contains the input types and input constraints, +does not contain transform output or the output-only pipe constraint, and leaves +all effect counters at zero. Use one helper assertion for the expected +structural schema so Zod 3/4 parity is obvious. + +Also add a Zod 3 preprocess regression: + +```ts +expect(() => + zodToJsonSchema( + z3.object({ + value: z3.preprocess((value) => Number(value), z3.number()), + }), + ), +).toThrow(/preprocess raw input cannot be represented structurally/); +``` + +This prevents a future broad `effects` allowance from introducing an early +sidecar rejection of input the complete Zod schema accepts. + +Before the fix, the new positive cases throw +`HostToolSchemaConversionError`. After the fix, both converter paths return the +same structural input contract. + +### One authoritative parse: +`packages/core/tests/toolkit-permissions.test.ts` + +Replace the monkey-patch in the test at lines 420-459 with a real schema before +VM creation. Use an asynchronous refinement so the test proves the +`safeParseAsync` change, plus a non-idempotent transform so a second parse is +observable: + +```ts +const inputSchema = z + .object({ value: z.number() }) + .refine(async ({ value }) => value > 0, "value must be positive") + .transform(({ value }) => { + transformCount += 1; + return { value: value + 1 }; + }); +``` + +Register that schema directly. For `{ value: 1 }`, assert registration succeeds, +the transform count is one, and `execute` receives/returns `{ value: 2 }`. Then +invoke the captured handler with `{ value: -1 }`; assert the response contains +`value must be positive`, `execute` is not called again, and the transform count +does not increase. + +Do not alter the permission expectations elsewhere in this file; they belong to +Item 62. + +### Real sidecar composition: +`packages/core/tests/sidecar-tool-dispatch.test.ts` + +Add a dedicated CLI-backed host tool with an asynchronous positive-number +refinement and a transform from `{ value }` to `{ value: value + 1 }`. Invoke it +through `agentos- --value 3`, not through a captured handler. +Assert: + +1. registration succeeds and the sidecar exposes/parses `--value` as a number; +2. the command exits zero; +3. `execute` receives `{ value: 4 }` (zero transforms would yield 3 and two + transforms would yield 5); and +4. the CLI JSON envelope returns that result. + +Run the command again with `--value -1`. It is structurally valid, so it must +reach the host; assert `execute` is skipped, the command exits nonzero, and +stderr contains the custom refinement message. Keep the existing missing-flag +test, which proves sidecar structural rejection still occurs before dispatch. + +No Zod behavior test should move into Rust: this item does not move behavior out +of TypeScript. Existing Rust tests remain the owner of generic structural flag +parsing and pre-dispatch rejection. + +## Risks and dependencies + +- **Item 25 / exactly one parse:** do not restore a second tool dispatcher or + parse.

Preprocess remains + explicitly rejected in this bounded fix. Do not claim Item 61 solves every + possible input coercion; that needs a separate permissive structural-schema + design and sidecar CLI behavior decision. +- **Examples remain raw inputs:** do not transform `tool.examples` during + registration. `packages/core/src/host-tools.ts:7-24` currently types examples + with the parsed `ZodType` output generic even though the sidecar consumes raw + input examples. That mismatch becomes visible only for shape-changing + transforms; avoid broadening Item 61 with a public generic redesign, keep its + tests example-free, and track raw-vs-parsed example typing separately. +- **Security:** every raw callback, including one originating from sidecar CLI + parsing, must still pass the complete original Zod schema before `execute`. + +## Dedicated revision and bounded diff + +Implement Item 61 in one new child `jj` revision stacked on the preceding item, +as required by `docs/thin-client-migration.md:25-31`.

Its focused tests at +`packages/core/tests/sidecar-permission-descriptors.test.ts:5-178` already prove +complete and partial omission is preserved. Item 62 should not change this +serializer. + +`AgentOs.create` builds the sidecar VM request at +`packages/core/src/agent-os.ts:1475-1502`; tool definitions are forwarded as +`hostCallbacks`, while permission defaults are not selected there. + +### The sidecar normalizes and enforces + +`permissions_with_allow_all_defaults` at +`crates/native-sidecar-core/src/permissions.rs:57-73` resolves both a wholly +omitted policy and omitted domains in a partial policy to allow-all. Native VM +creation applies it at `crates/native-sidecar/src/vm.rs:175-197`, before storing +the effective configuration. + +Tool command resolution performs the authoritative check in +`crates/native-sidecar/src/tools.rs:252-307`: + +```rust +evaluate_permissions_policy( + &vm.configuration.permissions, + "binding", + "binding.invoke", + Some(&callback_key), +) +``` + +Any result other than `Allow` returns +`blocked by binding.invoke policy for {callback_key}` before +`ToolCommandResolution::Invoke` and its `HostCallbackRequest` are constructed. +This ordering is the security property the moved tests must exercise. + +The adjacent native service tests at +`crates/native-sidecar/tests/service.rs:10530-10685` already cover: + +- an explicit all-binding deny causing command exit 1; and +- a matching `math:add` allow rule emitting one callback and returning success. + +They do not yet prove partial-policy omitted binding allows the callback, nor +that a non-matching rule denies without dispatch. The explicit-deny test also +does not install a counting callback handler, so its current result implies but +does not directly assert that no host callback was emitted. + +### The TypeScript callback intentionally contains no policy + +`handleHostCallback` at `packages/core/src/agent-os.ts:1014-1058` does exactly +the remaining host work: + +1. require a typed `host_callback` payload; +2. find the registered tool; +3. run the tool's complete Zod schema; and +4. execute it or return its host error. + +Its context at lines 1060-1072 contains only a tool map. It has no permissions, +and `_installSidecarRequestHandler` at lines 2816-2859 routes a sidecar callback +straight to it. This is correct. Reintroducing client permission state here +would duplicate the sidecar decision and recreate Item 3. + +`createVmCapturingHandler` in the test at current lines 23-56 spies on +`registerSidecarRequestHandler` and returns that handler as an ordinary +function. `created.handler(hostCallbackFrame(...))` therefore does not send a +guest request through the sidecar; it invokes the post-authorization host route +directly. The comments at current lines 7-21 incorrectly describe that as “the +bytes an untrusted guest controls” and must be rewritten. + +## Exact test edits + +### `packages/core/tests/toolkit-permissions.test.ts` + +#### Preserve the real command tests but correct omission + +Rename the current partial-policy case at lines 181-202 to approximately: + +```text +allows toolkit invocation when binding is omitted from a partial policy +``` + +Keep this input unchanged: + +```ts +permissions: { + fs: "allow", + childProcess: "allow", +}, +``` + +The omission itself is the subject. Change the assertions to exit code 0, +empty stderr, and the normal JSON result `{ ok: true, result: { sum: 12 } }`. +Do not add `binding: "allow"`; doing so would stop testing sidecar-owned partial +defaults. + +Keep the existing wholly omitted default-allow test and matching explicit-rule +test. Together they remain a thin TypeScript end-to-end check that the client +forwards toolkit definitions and explicit/omitted policy input without +interpreting it. + +#### Remove the two direct policy tests + +Delete the tests currently at lines 247-343: + +- `denies host_callback RPC tool invocation when binding.invoke policy is deny + (not just the CLI path)`; and +- `host_callback RPC respects binding.invoke pattern scope and denies a + non-matching tool`. + +Do not invert them into tests saying a denied callback “is allowed” when the +handler is called directly. That would document an impossible production route +and look like a security bypass. Their policy assertions move to the native +sidecar service test described below. + +#### Reframe the remaining captured-handler tests + +Replace the file header and the second `describe` title. State that the spy +captures the trusted sidecar-to-client callback route after authorization and +that synthetic invocation is only for host parsing/execution tests. A suitable +title is: + +```ts +describe("toolkit host callback validation", () => { ... }); +``` + +Retain these tests: + +- hostile/extra input is stripped and cannot pollute prototypes; +- a transform/refinement is applied exactly once; +- invalid Zod input never reaches `execute`; and +- a legacy command-shaped payload is treated only as tool input and rejected by + Zod, rather than reviving a client command dispatcher. + +For the hostile-input, invalid-input, and legacy-shape tests, remove the +`permissions` objects from `createVmCapturingHandler`. Those explicit +allow/deny settings are irrelevant after the test calls the handler directly +and currently imply policy is involved when it is not. Keep only +`{ toolKits: [kit] }`. + +Revise the security comments carefully: callback `input` is still untrusted and +must receive the complete host Zod parse, but the callback frame itself is +sidecar-originated after authorization. Do not weaken hostile-input or +single-parse assertions. + +Item 61 replaces the transform test's monkey-patched `safeParse` with a real +transform/refinement schema. Stack Item 62 after Item 61 and preserve that real +schema rather than restoring the current workaround. + +#### Correct the unrelated typed conflict assertion + +Import the already-exported `SidecarRequestRejected` from the Core root and +replace the obsolete message-prefix regex with an assertion on structured +fields: + +```ts +const creation = AgentOs.create({ + toolKits: [mathToolKit, duplicateMathToolKit], +}); +await expect(creation).rejects.toBeInstanceOf(SidecarRequestRejected); +await expect(creation).rejects.toMatchObject({ + code: "conflict", + message: "toolkit already registered: math", +}); +``` + +If Vitest's repeated `.rejects` handling is unclear for the same promise, use a +single `try/catch` and assert both the class and fields on the caught value. Do +not put `conflict:` back into the message; code and message are distinct sidecar +fields after Item 26. + +### `crates/native-sidecar/tests/service.rs` + +Keep all policy tests inside the existing included `service::tests` module and +the `run_service_suite` execution model; the file deliberately consolidates +V8-backed service work to avoid teardown/init crashes across many libtest cases. + +#### Strengthen explicit all-binding deny + +Rename +`tools_javascript_child_process_denies_host_callback_without_permission` to +approximately +`tools_javascript_child_process_explicit_binding_deny_skips_host_callback`. +The configuration already supplies +`binding: Some(PermissionMode::Deny)` and should remain explicit. + +Before spawning `agentos-math add`, install a handler backed by +`Arc` that increments if it receives a `HostCallback`. After the +existing exit-code/stderr assertions, assert the count is zero. Return an error +from the unexpected handler rather than relying only on the absence of a +configured handler. This proves authorization happens before host dispatch. +Reuse the exact counter/handler shape already present in this file at current +lines 10743-10753 and 10842-10861; no new test utility or dependency is needed. + +#### Add partial-policy omitted binding allow + +Add +`tools_javascript_child_process_omitted_binding_defaults_to_allow` beside the +existing deny/allow cases: + +1. create the VM with `fs: allow`, `child_process: allow`, and `binding: None`; +2. register `math:add`; +3. install a counting host-callback handler returning a known result; +4. spawn `/usr/local/bin/agentos-math add` through + `spawn_javascript_child_process_sync`; and +5. assert exit 0, the known JSON result, and invocation count 1. + +Use a partial `PermissionsPolicy`, not `PermissionsPolicy::allow_all()`.

The new class will +therefore reach finite `exec`/`execArgv`, `ManagedProcess.wait()`, and retained +`AgentOs.waitProcess` paths automatically. + +### ACP response + +`AgentOs._decodeAcpResponseEnvelope` at +`packages/core/src/agent-os.ts:2543-2559` receives both the original extension +envelope and decoded response. Its `AcpErrorResponse` branch at lines 2551-2556 +currently does this: + +```ts +const error = new Error(response.val.message) as Error & { + code?: string; +}; +error.code = response.val.code; +throw error; +``` + +The code/message survives, but the source `{ namespace, payload }` does not. +The live envelope is already defined at +`packages/runtime-core/src/ext.ts:4-7`. The generated response variant is at +`packages/core/src/sidecar/agentos-protocol.ts:908-923,959-969`, backed by +`crates/agentos-protocol/protocol/agent_os_acp_v1.bare:198-201,217-227`. + +`_sendAcpRequest` at `agent-os.ts:2561-2589` runs this same decoder for both the +optional response hook and the ordinary returned envelope. Replacing the one +throw site covers create/resume/session operations without changing routing. + +### Existing structured-error precedent + +`SidecarRequestRejected` at +`packages/runtime-core/src/sidecar-errors.ts:8-26` is the right model: an +exported `Error` subclass preserving exact code/message and its complete source +response frame.

Native and browser adapters both use the shared +response. Item 63 must not add another client code taxonomy. + +### Rust client parity + +Rust already exposes a public, downcastable enum instead of anonymous errors: + +- `crates/client/src/error.rs:14-38` defines `ClientError::Kernel { code, + message }`; +- `crates/client/src/process.rs:966-1000` maps terminal event errors to that + typed variant; and +- `crates/client/src/session.rs:1592-1621` maps decoded ACP errors to the same + typed variant without changing code/message. + +Rust does not retain a full event/envelope in that variant, but its caller can +already reliably identify the error and recover the authoritative fields. Item +63 explicitly tracks the TypeScript anonymous-error defect. Adding Rust wire +frame copies or new enum variants would expand the item and change a stable +public taxonomy without fixing a current loss of code/message. + +Behavioral parity remains: both clients return the same authoritative +code/message and neither interprets policy. TypeScript additionally follows its +existing `SidecarRequestRejected.response` convention by retaining the +JavaScript source object it already received. + +## Smallest production edit + +### 1. Add `packages/core/src/operation-errors.ts` + +Use only type imports from the already exported runtime-core subpaths: + +```ts +import type { LiveExtEnvelope } from + "@rivet-dev/agentos-runtime-core/ext"; +import type { LiveEventFrame } from + "@rivet-dev/agentos-runtime-core/protocol-frames"; + +export type ProcessTerminalErrorEvent = LiveEventFrame & { + payload: Extract< + LiveEventFrame["payload"], + { type: "process_exited" } + > & { error_code: string }; +}; + +/** A sidecar-reported guest-process terminal failure with its source event. */ +export class ProcessTerminalError extends Error { + readonly code: string; + readonly event: ProcessTerminalErrorEvent; + + constructor(event: ProcessTerminalErrorEvent) { + super(event.payload.error_message ?? event.payload.error_code); + this.name = "ProcessTerminalError"; + this.code = event.payload.error_code; + this.event = event; + } +} + +/** A decoded ACP adapter rejection with its original extension envelope. */ +export class AcpResponseError extends Error { + readonly code: string; + readonly envelope: LiveExtEnvelope; + + constructor(options: { + code: string; + message: string; + envelope: LiveExtEnvelope; + }) { + super(options.message); + this.name = "AcpResponseError"; + this.code = options.code; + this.envelope = options.envelope; + } +} +``` + +This is smaller and cleaner than publicly exposing the generated tagged ACP +union. The envelope is the requested complete source; callers already get the +decoded authoritative code/message as first-class properties. Do not add a +second decoded-response copy, code enum, retryability flag, message prefix, +errno conversion, or base class. + +Keep object identity rather than copying/freeze-cloning the frame or +`Uint8Array`. That matches `SidecarRequestRejected.response`, avoids client-owned +work, and lets tests prove the actual received wire object is inspectable. + +### 2. Edit `packages/core/src/sidecar/rpc-client.ts` + +Import `ProcessTerminalError` from `../operation-errors.js`. Replace only lines +840-845 with: + +```ts +if (event.payload.error_code !== undefined) { + this.failProcess( + entry, + new ProcessTerminalError(event as ProcessTerminalErrorEvent), + ); + continue; +} +``` + +Import `ProcessTerminalErrorEvent` as a type alongside the value. TypeScript +narrows the nested `event.payload`, but not the containing `event` object, so one +assertion is needed at this already checked protocol boundary. Do not rebuild a +partial frame to avoid it. + +Do not change the event pump, process route lifecycle, output capture, callback +order, or error identity after `failProcess`. + +### 3. Edit `packages/core/src/agent-os.ts` + +Import `AcpResponseError` from `./operation-errors.js`. Replace only the +`AcpErrorResponse` body at lines 2551-2556: + +```ts +if (response.tag === "AcpErrorResponse") { + throw new AcpResponseError({ + code: response.val.code, + message: response.val.message, + envelope, + }); +} +``` + +Do not move BARE decoding into the class. Wrong namespace and decode failures +remain malformed transport/input errors, not adapter-owned operation +rejections. + +### 4. Edit `packages/core/src/index.ts` + +Add root exports next to the existing public error exports: + +```ts +export { + AcpResponseError, + ProcessTerminalError, +} from "./operation-errors.js"; +export type { ProcessTerminalErrorEvent } from "./operation-errors.js"; +``` + +No actor-package re-export is needed. These errors are thrown by direct +`@rivet-dev/agentos-core` VM/session calls; actor actions cross a serialized +boundary and do not expose these core objects by identity. + +### 5. Document the public behavior + +Add a compact “Operation errors” subsection to +`website/src/content/docs/docs/core.mdx` after the direct process/session API +sections. State that `ProcessTerminalError` retains `.code` and `.event`, while +`AcpResponseError` retains `.code` and `.envelope`, and that these values are the +unmodified sidecar/adapter result. No runnable example is needed. + +The class JSDoc is still required because the website TypeDoc entry point is the +actor package rather than the core package; the public core declarations are the +authoritative API documentation for direct consumers. + +## Exact red/green tests + +### Process terminal: `packages/core/tests/process-event-ordering.test.ts` + +At lines 7-58, replace the loose `PumpEvent` fixture with full live frames while +keeping existing call sites compact: + +```ts +import type { LiveEventFrame } from + "@rivet-dev/agentos-runtime-core/protocol-frames"; +import { SIDECAR_PROTOCOL_SCHEMA } from + "@rivet-dev/agentos-runtime-core/protocol-schema"; +import { + ProcessTerminalError, +} from "../src/index.js"; + +// queue and waitForEvent use LiveEventFrame +pushEvent(event: Omit) { + const frame: LiveEventFrame = { + frame_type: "event", + schema: SIDECAR_PROTOCOL_SCHEMA, + ...event, + }; + queue.push(frame); + notify?.(); + return frame; +} +``` + +Add a test that spawns, starts `proc.wait()`, and pushes one terminal event with +distinct ownership, process ID, exit code, stdout, stderr, `error_code`, and +`error_message`. Capture the rejection once and assert: + +- `error instanceof ProcessTerminalError`; +- exact unmodified `name`, `code`, and `message`; +- `error.event === sourceEvent`; +- representative ownership/process/exit fields; and +- the same stdout/stderr byte objects remain reachable through the event. + +Before implementation, `ProcessTerminalError` is not exported and the plain +error has no `.event`. After implementation, the same test proves the full +received frame survives the route. + +### Real process integration: `packages/core/tests/execute.test.ts` + +At lines 96-109, import `ProcessTerminalError`, capture the real sidecar +rejection once, and add: + +```ts +expect(error).toBeInstanceOf(ProcessTerminalError); +expect(error).toMatchObject({ + code: "ERR_CAPTURED_OUTPUT_LIMIT_EXCEEDED", + message: expect.stringContaining( + "limits.jsRuntime.capturedOutputLimitBytes", + ), +}); +expect(error.event.payload).toMatchObject({ + type: "process_exited", + error_code: "ERR_CAPTURED_OUTPUT_LIMIT_EXCEEDED", +}); +``` + +This keeps the existing functionality assertion and proves a real native +sidecar event reaches the new class. The cheap ordering test remains the exact +identity test. + +### ACP error: `packages/core/tests/session-route-registration.test.ts` + +Add a standalone injected-agent test using the public root export. Its fake +`extensionRequest` should intentionally ignore the optional response hook and +return this exact object: + +```ts +const sourceEnvelope = { + namespace: ACP_EXTENSION_NAMESPACE, + payload: encodeAcpResponse({ + tag: "AcpErrorResponse", + val: { + code: "adapter_rejected", + message: "adapter said no", + }, + }), +}; +``` + +Call `agent.createSession("test-agent")`, capture the rejection once, and +assert: + +- `error instanceof AcpResponseError`; +- exact `name`, `code`, and message; +- `error.envelope === sourceEnvelope` and the payload bytes are the same object; +- no session route was created. + +This exercises `_sendAcpRequest` and the public create path without calling the +private decoder directly. Current code fails only the class/context assertions; +the final implementation must not create a route before rejecting. + +### Root contract: `packages/core/tests/public-api-exports.test.ts` + +Import both classes and `ProcessTerminalErrorEvent` from `../src/index.js`. +Assert both values are functions and reference the event type in the existing +type-export test. This prevents an internal-only implementation consumers +cannot identify with `instanceof`. + +No Zod, sidecar, protocol, generated-code, or Rust test should move. This item +changes JavaScript error presentation after authoritative data already arrived; +the existing sidecar/runtime tests remain the owner of wire production and +conversion. + +## Dependencies, overlap, and risks + +- **Item 26 is the precedent:** it introduced + `SidecarRequestRejected.response`.

Document + them as diagnostic source data, not mutable client policy state. +- **Malformed envelopes remain separate:** unexpected namespace and codec + errors are not authoritative ACP operation responses and must remain ordinary + transport/decode failures. +- **No new limits/defaults:** the classes add no queue, cache, retry, timeout, or + policy. + +## Dedicated JJ revision and bounded diff + +Implement Item 63 in one new child `jj` revision stacked on the preceding item, +as required by `docs/thin-client-migration.md:25-31`.

Its current +`Display` implementation encodes machine semantics into message text: + +```rust +"[invalid_schedule] invalid cron schedule: ..." +"[past_schedule] one-shot cron schedule is in the past: ..." +``` + +Those markers exist only because the adapters discard the enum variant. + +### Native adapter flattens both to `invalid_state` + +`NativeSidecar::schedule_cron` at +`crates/native-sidecar/src/service.rs:1498-1538` calls +`.map_err(cron_scheduler_error)`.

Therefore no information is lost on the wire or during the +first TypeScript mapping: only the three final plain-`Error` constructions lose +the structured object. + +Native, browser, and shared ACP sidecar code already use ordered cleanup error +variants (`SidecarError::Cleanup`, `BrowserSidecarError::Cleanup`, and +`AcpCoreError::Cleanup`) and map them to `cleanup_failed`. Those variants cover +multiple failures that occur *inside one sidecar operation*. Adding a wire list +of causes would not solve this item: the TypeScript host is combining multiple +already-completed requests/transports and is the only layer that knows all of +those children. Host aggregation is consequently required lifecycle routing, +not client-owned runtime policy. + +Rust deliberately uses one wire session per VM and `AgentOs::shutdown` sends a +single `CloseSession` transaction. It has no corresponding multi-session host +aggregate to implement. `crates/client/src/sidecar.rs:248-273` nevertheless has +an always-empty `errors: Vec` and an unreachable fallback whose comment +describes the TypeScript bug. Delete that dead scaffold in this revision so the +Rust client remains simple and does not preserve obsolete parity guidance. Do +not add a Rust aggregate error variant merely to mirror JavaScript's standard +`AggregateError`. + +## Exact remaining failures + +### Session cleanup discards VM and transport failures + +`AgentOsSidecarClient.disposeSession` currently collects the right objects in +the right order: + +1. one error for each VM entry, in `Map` insertion order; then +2. the session transport's `dispose` error. + +The loss occurs only at current lines 1364-1369: + +```ts +entry.lifecycle.lastError = errors + .map((error) => error.message) + .join("; "); +throw new Error(entry.lifecycle.lastError); +``` + +`toError` at current lines 1585-1587 returns an existing `Error` unchanged, so +the collected array still contains the exact `SidecarRequestRejected` or other +typed errors.

Its message and +retry expectations should continue to pass unchanged. + +Use identity assertions, not deep equality, for the leaves: + +```ts +expect(error).toBeInstanceOf(AggregateError); +const aggregate = error as AggregateError; +expect(aggregate.errors).toHaveLength(2); +expect(aggregate.errors[0]).toBe(vmError); +expect(aggregate.errors[1]).toBe(transportError); +``` + +### Shared-sidecar cleanup unit test + +Add `packages/core/tests/shared-sidecar-cleanup-errors.test.ts`: + +- call `__disposeAllSharedSidecarsForTesting()` before arranging the test so + unrelated cached handles cannot affect insertion order; +- acquire two unused handles with unique pools through + `AgentOs.getSharedSidecar` (unused handles spawn no native process); +- use `vi.spyOn(handle, "dispose").mockRejectedValue(...)` to inject two real + structured errors; +- call `__disposeAllSharedSidecarsForTesting`; +- assert both spies ran once even though the first rejected; +- run this desired assertion before the production edit and record that it + receives a plain joined-message error; and +- assert `AggregateError.errors` contains the two injected + objects in pool insertion order and the message retains the shared-sidecar + context. + +The helper clears `sharedSidecars` before disposal. In `finally`, restore both +spies and call both real `dispose()` methods with `Promise.allSettled`; no native +process was spawned, but this leaves both detached handles terminal rather than +merely relying on garbage collection. + +### Public lease/injected-transport regression + +Add one focused case to `packages/core/tests/sidecar-placement.test.ts` named +`preserves a typed VM-admin failure through lease cleanup`: + +1. create an explicit sidecar and one `AgentOs` VM with + `defaultSoftware: false`; +2. obtain the test-visible `_sidecarLease.admin` through the same narrow + structural cast style already used by lifecycle tests; +3. temporarily make `admin.dispose()` reject with a real + `SidecarRequestRejected`; +4. call `sidecar.dispose()` and recursively inspect `AggregateError.errors`; +5. before the remaining edit, the source rejection disappears at + `AgentOsSidecarClient.disposeSession`; after it, the exact source object is a + nested leaf through the already-compliant injected transport, session + client, lease, and sidecar aggregates; and +6. restore `admin.dispose`, then dispose the VM and sidecar successfully to + prove all retained cleanup state is retryable. + +This is the regression that closes the tracker's lease and injected-transport +language without exposing a new test-only production API or rewriting code that +is already correct. Assert the exact source object is found recursively; do not +assert a brittle number of wrapper levels. + +Use a small recursive helper whose base case is object identity: + +```ts +function containsError(error: unknown, target: Error): boolean { + if (error === target) return true; + return ( + error instanceof AggregateError && + error.errors.some((child) => containsError(child, target)) + ); +} +``` + +Also strengthen +`packages/core/tests/leak-rpc-client.test.ts:187-225` by retaining the injected +`disposeVm` error object and asserting the first rejected `proxy.dispose()` is +an `AggregateError` whose first child is that exact object. This guards an +already-compliant adjacent path and proves its retry behavior did not regress. +This assertion should already pass before the production edit; record it as the +before/after guard, not as one of the red regressions. + +### Focused validation + +Add the four desired structured-error regressions before changing production +code, then run the first command and save the failures as the tracker's +"validated before" evidence. The session, whole-client, shared-sidecar, and +public lease-chain tests must fail on the old plain-error sites; the strengthened +proxy identity/retry assertion must already pass. After applying the production +edit, rerun the complete list: + +```sh +pnpm --dir packages/core exec vitest run tests/sidecar-client.test.ts tests/shared-sidecar-cleanup-errors.test.ts tests/sidecar-placement.test.ts tests/leak-rpc-client.test.ts --reporter=verbose +pnpm --dir packages/core check-types +cargo fmt --all -- --check +cargo test -p agentos-client sidecar::tests +pnpm --dir website build +git diff --check +``` + +The current pre-edit baseline for the three existing TypeScript files is 11/11 +passing, and the Rust sidecar unit filter is 8/8 passing: + +```sh +pnpm --dir packages/core exec vitest run tests/sidecar-client.test.ts tests/sidecar-placement.test.ts tests/leak-rpc-client.test.ts --reporter=verbose +cargo test -p agentos-client sidecar::tests +``` + +No protocol fixture regeneration, native-sidecar test, or browser-adapter test +is required. The Rust unit command is sufficient because its edit only removes +an unreachable branch, and the website build covers the one documentation +sentence. + +## Risks and dependencies + +- **Preserve retry semantics.** Do not set session/client/sidecar state to + disposed until every current cleanup operation succeeds. This item changes + only the error object returned from failed attempts. +- **Preserve exact `Error` identity.** `toError` already does this for real + errors. Continue normalizing non-`Error` throws, but never clone or reconstruct + `SidecarRequestRejected` children. +- **Keep deterministic order.** VM/session/sidecar `Map` insertion order is the + observable `.errors` order and should match cleanup attempt order. +- **Keep nested transaction context.** A client-level aggregate should contain + per-session aggregates. Flattening them into one leaf list would make the + client more complicated and discard useful transaction boundaries. +- **Joined messages are not themselves the bug.** They are acceptable display + text when the original child objects are also retained. Removing child + messages from `AggregateError.message` would unnecessarily break existing + `.toThrow(message)` coverage and degrade logs that do not print `.errors`. +- **Node support is sufficient.** The package requires Node 20 and already uses + `AggregateError` in the same source files; no polyfill or custom class is + needed. +- **Items 59 and 60 may also create `AggregateError`.** Reuse this ordering rule: + primary operation error first, cleanup error second. They do not block Item + 65 and should stay in their own revisions. +- **Item 63 is complementary.** Once process-terminal and ACP errors become + exported structured classes, these cleanup aggregates will preserve them + automatically. Item 65 must not add knowledge of those classes or codes. +- **Warning-only startup cleanup is separate.** `AgentOs.create` and failed lease + creation currently log some secondary cleanup failures while returning the + primary error. That deserves its own fail/retry analysis because it is not a + multi-error string flattener and can affect resource ownership. Do not expand + this small representation fix without a dedicated tracker item. +- **Rust parity is semantic, not type-name parity.** JavaScript has a standard + `AggregateError`; Rust does not need a new public enum variant when it performs + only one authoritative close operation. Retain/downcast the existing typed + `ClientError` instead of manufacturing a message-only aggregate. + +## Dedicated `jj` revision boundary + +Use one dedicated stacked revision, for example +`fix(client): preserve structured cleanup errors`, containing only: + +- `packages/core/src/sidecar/rpc-client.ts`; +- the three-line error-representation change in + `packages/core/src/agent-os.ts`; +- `packages/core/tests/sidecar-client.test.ts`; +- `packages/core/tests/shared-sidecar-cleanup-errors.test.ts`; +- the focused public-chain regression in + `packages/core/tests/sidecar-placement.test.ts`; +- the identity assertion in + `packages/core/tests/leak-rpc-client.test.ts`; +- dead parity-scaffold removal in `crates/client/src/sidecar.rs`; +- the disposal-contract sentence in + `website/src/content/docs/docs/core.mdx`; and +- the Item 65 checklist/status update in + `docs/thin-client-migration.md` after all focused tests pass. + +Do not include lease-state refactors, startup cleanup redesign, sidecar/protocol +changes, other Rust changes, custom error types, or work from Items 59, 60, or +63.

Two users +passing the same descriptors can also get different package sets based on the +client process's host filesystem and checkout layout. + +## Exact current code and behavior + +### Package probing and substitution in `packages/shell/src/main.ts` + +The complete policy is concentrated near the top of the file: + +- lines 16-27 import `existsSync`, `statSync`, path joining/directory helpers, + and `fileURLToPath` for package inspection/fallback resolution; +- lines 56-63 derive `workspaceRoot` from the shell module and hard-code + `registry/native/target/wasm32-wasip1/release/commands` as + `fallbackCommandDirs`; +- lines 90-96 introduce the local, permissive `RegistryPackage` type; +- `isUsablePackageDir` at lines 98-101 requires a host-side + `agentos-package.json`; +- `isUsablePackageFile` at lines 103-110 calls `statSync` and converts every + failure into `false`; and +- `withLocalCommandFallback` at lines 112-134 replaces a bad selected path with + the first usable fallback directory, otherwise warns and returns `null`. + +The main static list at lines 136-160 contains 21 package descriptors and runs +them through `.map(withLocalCommandFallback).filter(...)`. It selects, in order: + +```text +coreutils, sed, grep, gawk, findutils, diffutils, tar, gzip, curl, zip, +unzip, jq, ripgrep, fd, tree, file, yq, codex, git, httpGet, sqlite3 +``` + +The editor loop at lines 162-184 applies a separate policy to `[vix, vim]`: + +1. forward a host path only if `statSync(...).isFile()`; +2. for a directory, require `agentos-package.json`; +3. read and parse `package.json` in the client; +4. include it only if `bin` is a non-empty object; and +5. silently omit unreadable, placeholder, or commandless packages. + +Finally, lines 692-698 pass the altered `software` array to either +`createActorShellVm` or `AgentOs.create`, with `defaultSoftware: false`. +Therefore all fallback and omission decisions happen before either sidecar +route receives a request. + +### The registry modules already provide serializable inputs + +Each selected `@agentos-software/*` module exports the same kind of descriptor. +For example, `registry/software/coreutils/src/index.ts` computes the URL of its +packed `package.aospkg` and exports: + +```ts +export default { packagePath } satisfies SoftwarePackageRef; +``` + +The corresponding modules for `codex-cli`, `vix`, `vim`, and the remaining +software do the same. The shell does not need to reinterpret those descriptors. +Selecting this default package list in TypeScript is the explicit package-manager +exception to the thin-client rule; validating the selected artifacts is not. + +### The normal client paths already serialize package paths + +No protocol or production sidecar change is required: + +- `normalizePackageRef` in `packages/core/src/agent-os.ts:672-690` accepts a raw + path or `{ packagePath }` and returns the path without reading it; +- `AgentOs.create` at `agent-os.ts:1368-1403` flattens the package-manager input, + removes exact duplicate path strings, and sends `{ path: ref.path }` entries; +- `normalizePackageRef`/`normalizedPackageRefs` in + `packages/agentos/src/actor.ts:103-128` perform the equivalent structural + actor serialization; and +- `buildConfigJson` at `actor.ts:130-149` emits those paths in `packages`. + +Keep these paths structural. Item 66 must not add `stat`, `realpath`, inode, +manifest, command, or package-content inspection to either normalizer as a new +way to identify packages. Exact path-string forwarding/deduplication is the +current bounded behavior. + +### The sidecar is already the semantic owner + +The native sidecar consumes the forwarded path at the correct enforcement +point: + +- `package_descriptor_from_wire` in + `crates/native-sidecar/src/vm.rs:1558-1575` sends every wire `PackagePath` to + `read_package_manifest_from_path`; +- VM configuration at `vm.rs:463-507` resolves descriptors, validates their + projected commands/agent bundle/provides, and builds package mounts; +- `read_package_manifest_from_path` in + `crates/native-sidecar/src/package_projection.rs:349-388` rejects an empty + path, reads a file as a packed `.aospkg`, or treats a directory as a transition + package; and +- `read_package_manifest_from_dir` at `package_projection.rs:199-246` rejects a + transition directory without `package.aospkg` or `agentos-package.json`, reads + the manifest, derives commands/manpages, and returns typed sidecar errors. + +Projection validation continues at `build_package_leaf_mounts` beginning at +`package_projection.rs:390`, including duplicate commands and invalid ACP +entrypoints. A nonexistent selected path naturally reaches +`read_package_manifest`, then produces the existing sidecar package-dir error. +That error is preferable to a shell substitution because it names the selected +path and stops VM creation. + +## Exact production edits + +### Add `packages/shell/src/software.ts` + +Move the 23 package imports out of the executable `main.ts` and export one +data-only array. Preserve the current selection and exact order, including +`vix` before `vim`: + +```ts +import codex from "@agentos-software/codex-cli"; +import coreutils from "@agentos-software/coreutils"; +// ...the remaining existing package imports... +import type { SoftwareInput } from "@rivet-dev/agentos-core"; + +export const shellSoftware = [ + coreutils, + sed, + grep, + gawk, + findutils, + diffutils, + tar, + gzip, + curl, + zip, + unzip, + jq, + ripgrep, + fd, + tree, + file, + yq, + codex, + git, + httpGet, + sqlite3, + vix, + vim, +] satisfies SoftwareInput[]; +``` + +This module must contain no `node:fs`, `node:path`, or `node:url` import and no +function that filters, copies, resolves, canonicalizes, or validates a package +descriptor. A separate module is useful because importing `main.ts` executes the +CLI and creates a VM, while the data-only selection can be tested directly. + +### Simplify `packages/shell/src/main.ts` + +1. Remove all 23 `@agentos-software/*` imports and the `SoftwareInput` type + import. +2. Import `shellSoftware` from `./software.js`. +3. Delete `__dirname`, `workspaceRoot`, and `fallbackCommandDirs`. +4. Delete `RegistryPackage`, `isUsablePackageDir`, `isUsablePackageFile`, + `withLocalCommandFallback`, the mapped/filtered `software` declaration, and + the entire editor loop. +5. Pass `software: shellSoftware` to both `createActorShellVm` and + `AgentOs.create`, retaining `defaultSoftware: false`. +6. Reduce the Node imports to what the rest of this file actually uses: + `readFileSync` from `node:fs` and `basename`/`resolve` from `node:path`. + Remove `node:os` and `node:url`. + +Do **not** remove `readFileSync(resolve(envFilePath), "utf8")` at approximately +line 344. `--env-file` is an explicit caller-supplied host input, so parsing it +is CLI input handling rather than package/runtime bootstrap. Likewise, retain +host-path normalization for explicit `--volume`/`--mount` values. + +### Do not change production sidecar code + +The sidecar already owns package existence, format, manifest, command, +entrypoint, and projection validation. Item 66 needs test coverage for that +existing behavior, not a fallback, package default, or alternate build-output +directory in Rust. + +## Development-build behavior + +The removed fallback was attempting to make an incompletely built checkout +start. That responsibility already has a better home: + +- `justfile:52-86` scans the shell's linked package outputs and builds missing + registry packages before launching; +- `justfile:87-96` builds the common/core/actor TypeScript outputs when needed; +- `justfile:115-132` builds and pins the in-repo native sidecar; and +- `packages/shell/CLAUDE.md:1-8` tells contributors that `just shell` repairs + dependencies, rebuilds missing shell software, and that the shell loads every + command-providing registry package. + +Keep this development preflight in the recipe/toolchain. Directly invoking a +published or workspace shell with a missing package should fail through the +sidecar; it should not fabricate a different package set. No filesystem access +is needed in the shell startup path to bootstrap packages. + +## Test plan + +### Before-behavior evidence + +The tracker explicitly asks for proof that the old client policy changes input +before a sidecar request. Capture that evidence before deleting the code: + +1. Extract the current selection logic unchanged into a testable helper as an + intermediate local step, or test a temporarily exported helper. +2. Stub `statSync`/`existsSync` so a selected descriptor is missing while the + native fallback directory appears usable. Assert the returned entry contains + the fallback path and not the selected path. +3. Stub both selected and fallback paths as missing. Assert the selected entry + is absent and the warning fires. +4. Stub a `vix`/`vim` directory with an unreadable or empty `package.json`. Assert + it is absent without creating `AgentOs` or invoking `createActorShellVm`. + +Record the focused passing test command and vulnerable parent revision in the +Item 66 tracker evidence. These old-policy assertions should not remain in the +final revision; replace them with forwarding assertions. + +Research-time baseline evidence at `d9eedb7278b9`: + +| Check | Result | +|---|---| +| Source inventory of `packages/shell/src/main.ts:98-184` | **Vulnerable behavior present:** selected paths are statted, substituted with one local fallback, warned/skipped, or omitted after editor-manifest reads before either VM factory runs. | +| `cargo test -p agentos-native-sidecar --test package_projection` | **Pass: 11 passed.** Existing sidecar tests cover transition/packed projection, missing manifest, duplicate command, and invalid entrypoint behavior. | +| `pnpm --dir packages/core exec vitest run tests/options-schema.test.ts --fileParallelism=false` | **Pass: 12 passed.** Future/nonexistent-looking refs remain structurally valid. | +| `AGENTOS_SIDECAR_BIN=$PWD/target/debug/agentos-sidecar pnpm --dir packages/agentos exec vitest run tests/actor.test.ts --fileParallelism=false` | **Pass: 15 passed.** The environment variable is required in this checkout because the optional platform package is not installed. | +| `pnpm --dir packages/shell check-types` | **Environment-blocked before Item 66:** several selected registry packages and `@rivet-dev/agentos` declarations have not been built.

A small source-boundary assertion for forbidden package +probe names is acceptable because absence of host filesystem policy is part of +the architecture contract. + +Keep the existing `packages/shell/tests/cli.test.ts` smoke coverage. It tests +real shell commands, mounts, environment input, stdin, and direct/actor launch; +it should continue to use the fully built package registry from the test +preflight. + +### After: sidecar reports bad refs and projects good refs + +Extend `crates/native-sidecar/tests/package_projection.rs` with focused calls to +`read_package_manifest_from_path`: + +- pass a nonexistent path and assert the sidecar returns an error containing + that original path/package-dir context; and +- write a corrupt file with an `.aospkg` name, pass it unchanged, and assert the + vbare/package-header error is returned. + +Retain the existing tests: + +- `reads_version_from_agentos_package_json_and_errors_when_missing` proves an + empty transition directory is rejected; +- `reads_manifest_and_commands_from_package_tar_without_extracting` proves a + good packed package is read; +- the tar and transition-dir mount tests prove both projection forms; and +- duplicate-command and invalid-agent-entrypoint tests prove semantic errors + remain sidecar-owned. + +The TypeScript and actor serializer coverage at +`packages/core/tests/options-schema.test.ts:57-84` and +`packages/agentos/tests/actor.test.ts:450-471` already proves nonexistent/future +paths are structurally accepted and emitted unchanged.

The shell package test builds and launches the real +CLI, so it is the expensive check; the data-only selection test should diagnose +Item 66 failures first. + +## Bounded JJ revision + +Item 66 must be one dedicated stacked `jj` revision containing only: + +```text +packages/shell/src/main.ts +packages/shell/src/software.ts +packages/shell/tests/software.test.ts +crates/native-sidecar/tests/package_projection.rs +docs/thin-client-migration.md +``` + +The Rust file is test-only.

A thrown handler invalidates that +host dispatch, later handlers are not called, and even a reply synchronously +attempted before the throw is discarded for this sidecar callback.

Host code must not execute inside the promise executor. + +## Exact current code and failure mechanics + +### Pending route shape + +`AgentSessionEntry` in `packages/core/src/agent-os.ts:208-228` owns: + +```ts +pendingPermissionReplies: Map< + string, + { + resolve: (reply: PermissionReply) => void; + reject: (error: Error) => void; + cleanupTimer: ReturnType; + } +>; +``` + +This is legitimate host-only correlation. The sidecar cannot call a JavaScript +closure directly, while `respondPermission(sessionId, permissionId, reply)` +must find the exact callback wait associated with the session and permission. +`sessionEntryFromRoute` initializes the map at current lines 774-789. + +### Handler invocation occurs inside a `Promise` executor + +`_handleAcpPermissionCallback` at current +`packages/core/src/agent-os.ts:2908-2961`: + +1. returns `undefined` for an unknown session; +2. returns `undefined` and emits the no-handler warning when the handler set is + empty; +3. constructs a `Promise` at lines 2927-2953; +4. installs the cleanup timer and pending map entry at lines 2928-2940; and +5. invokes every handler at lines 2950-2952 **inside that executor**. + +JavaScript catches a synchronous exception thrown by a promise executor and +turns it into a rejection of that promise. It does not unwind through the code +that installed the pending map entry. The outer `await` catches the rejection at +lines 2954-2960, logs it, and returns `undefined`, but neither deletes the entry +nor clears the timer. + +Iteration also stops at the throwing handler. That behavior is currently an +incidental consequence of the throw. Item 67 should retain it deliberately as +fail-fast behavior and cover it with a named assertion. + +There is a second promise-settlement edge: + +```ts +vm.onPermissionRequest(sessionId, (request) => { + void vm.respondPermission(sessionId, request.permissionId, "always"); + throw new Error("handler failed after replying"); +}); +``` + +`respondPermission` runs synchronously up to its returned resolved promise. It +deletes the pending entry, clears the timer, and calls the stored `resolve`. +When the handler then throws, the `Promise` constructor calls `reject`, but the +promise has already resolved. The outer catch never runs and the callback +returns `"always"`. Moving handler execution outside the executor makes the +throw authoritative for host-route validity and causes the sidecar callback to +receive `null` instead. + +### Stale reply API behavior + +`respondPermission` at `agent-os.ts:2997-3020` deletes and clears a route only +when the host explicitly replies. Because the thrown-handler path leaves the +entry behind, a later caller can receive a successful local JSON-RPC-shaped +result with `via: "sidecar-request"` even though the actual sidecar request has +already completed with no host reply. Once Item 67 removes the route, the same +call correctly throws: + +```text +Permission request is not pending: +``` + +Session close/dispose cleanup at `agent-os.ts:2645-2666` already clears timers +and rejects all still-valid pending routes. Do not change that lifecycle +behavior in Item 67. + +## The sidecar already owns the failure outcome + +No protocol or Rust production change is required. + +`_handleAcpExtSidecarRequest` at `agent-os.ts:2850-2905` decodes the generated +`AcpPermissionCallback`, awaits `_handleAcpPermissionCallback`, and encodes: + +```ts +{ + tag: "AcpPermissionCallbackResponse", + val: { + permissionId: callback.val.permissionId, + reply: reply ?? null, + }, +} +``` + +The generated field comment in +`packages/core/src/sidecar/agentos-protocol.ts:1321-1327` explicitly says the +client supplies only an explicit host answer and the sidecar owns the default +when the route is absent, times out, or fails. + +On the native sidecar: + +- `build_inbound_response` in + `crates/agentos-sidecar/src/acp_extension.rs:1986-2054` creates the typed + callback, owns `PERMISSION_CALLBACK_TIMEOUT`, and waits for the host route; +- `permission_callback_reply` at `acp_extension.rs:2874-2881` maps a missing + reply to `"reject"`; +- `permission_callback_reply_from_result` at lines 2883-2898 applies the same + sidecar default on the authoritative callback timeout; and +- the existing unit test + `missing_client_permission_reply_uses_sidecar_default` at lines 3151-3171 + proves `reply: None` becomes the sidecar default while an explicit `once` + remains `once`. + +The TypeScript callback must return a valid typed response with `reply: null` +rather than throw out through the protocol handler. A thrown `ext` handler is +converted by `packages/runtime-core/src/callbacks.ts:69-95` to an `ext_result` +whose payload is raw error text; Rust cannot decode that text as +`AcpCallbackResponse`, so it becomes a transport/protocol error rather than the +sidecar-owned permission default. + +## Exact production edit + +Change only `_handleAcpPermissionCallback` in +`packages/core/src/agent-os.ts`. + +### 1. Restrict the `Promise` executor to route setup + +Create the reply promise, timer, and map entry first, with no user callback in +the executor: + +```ts +const replyPromise = new Promise((resolve, reject) => { + const cleanupTimer = setTimeout(() => { + session.pendingPermissionReplies.delete(permissionId); + reject( + new Error( + `Permission reply route expired after the sidecar deadline: ${permissionId}`, + ), + ); + }, cleanupAfterMs); + session.pendingPermissionReplies.set(permissionId, { + resolve, + reject, + cleanupTimer, + }); +}); +``` + +Keep the current sidecar-provided `cleanupAfterMs`; Item 68 owns removal of the +post-decision grace timer after the protocol gains explicit cancellation or +expiry acknowledgement. + +### 2. Dispatch handlers in an explicit fail-fast block + +Build the existing raw `PermissionRequest`, then invoke a snapshot in +registration order: + +```ts +try { + for (const handler of [...session.permissionHandlers]) { + handler(permissionRequest); + } +} catch (error) { + const pendingReply = session.pendingPermissionReplies.get(permissionId); + if (pendingReply) { + session.pendingPermissionReplies.delete(permissionId); + clearTimeout(pendingReply.cleanupTimer); + } + console.warn( + `ACP permission handler failed for ${sessionId}/${permissionId}; the host route was removed and the sidecar owns the outcome`, + error, + ); + return undefined; +} +``` + +Snapshotting the set prevents handler registration/removal during delivery from +changing which already-registered handlers belong to this dispatch. Stop on the +first failure. Do not call `pendingReply.reject(error)`: this function is no +longer awaiting `replyPromise` on the failure path, so rejecting it would create +an unhandled rejection. Clearing the sole timer and dropping the map entry makes +the now-unreachable pending promise collectable. + +If an earlier handler already called `respondPermission`, the map entry and +timer are already gone. Still log the later failure and return `undefined`; +ignore the resolved `replyPromise`. This is how the client avoids selecting the +permission result after incomplete host fanout. + +### 3. Await the reply only after successful delivery + +Retain the current route-expiry/session-close warning behavior around the wait: + +```ts +try { + return await replyPromise; +} catch (error) { + console.warn( + `ACP permission callback route closed for ${sessionId}/${permissionId}; the sidecar owns the outcome`, + error, + ); + return undefined; +} +``` + +Do not add an implicit `"reject"`, `"once"`, or `"always"` result in either +catch. Do not add a client retry or re-run failed handlers. + +### Async handler returns are outside this bounded item + +The public core `PermissionRequestHandler` currently returns `void`. Item 67 is +specifically the synchronous exception path. Do not silently change it to an +awaited multi-handler API in this revision: that changes callback ordering and +how much of the sidecar deadline a handler may consume. A separately tracked +API decision can widen it to `void | Promise` with explicit rejection and +deadline tests if core users need asynchronous handlers. The actor-level +`onPermissionRequest` hook in `packages/agentos` is a different API and already +declares `void | Promise`. + +## Before and after tests + +Add a focused `packages/core/tests/permission-handler-failure.test.ts`. Use +`Object.create(AgentOs.prototype)` plus a narrow `_sessions` injection, matching +`session-config-routing.test.ts` and `permission-no-handler-warning.test.ts`. +This avoids starting a sidecar merely to prove host correlation cleanup. + +Import `encodeAcpCallback` and `decodeAcpCallbackResponse` from the generated +AgentOS protocol module and drive `_handleAcpExtSidecarRequest` with a real +`dev.rivet.agent-os.acp` envelope. Testing the full private envelope method, +rather than only `_handleAcpPermissionCallback`, proves the reply sent back to +the sidecar is structurally valid and null. + +### Before-behavior evidence + +With fake timers, register two handlers. The first throws a retained `Error` +object synchronously and the second is a spy. On the vulnerable parent: + +1. the returned callback response decodes with `reply: null`; +2. the first handler ran and the second did not; +3. `pendingPermissionReplies` still contains the permission ID immediately + after the callback returned; +4. `vi.getTimerCount()` reports the live cleanup timer; and +5. the warning contains the exact thrown error. + +Advance to `cleanupAfterMs` and prove only then does the entry disappear. Record +this passing vulnerable-parent command/revision in the tracker, then replace +the stale-route expectations with the after assertions. + +### After: thrown handler removes the route immediately + +The lasting regression should assert, before advancing fake time: + +- the encoded response is `AcpPermissionCallbackResponse` for the exact + permission ID with `reply: null`; +- the first handler ran once and the second did not (documented fail-fast + delivery); +- the pending map no longer contains the route and the cleanup timer count is + zero; +- `respondPermission` rejects with `Permission request is not pending`; +- `console.warn` includes the session ID, permission ID, sidecar-owns-outcome + text, and the exact original `Error` object; and +- advancing beyond `cleanupAfterMs` produces no delayed cleanup side effect or + second warning. + +### After: a reply followed by a throw is not accepted + +Add a second case whose handler calls +`void agent.respondPermission(..., "always")` and then throws synchronously. +Assert the envelope still decodes to `reply: null`, the handler failure is +logged, and the route/timer are absent.

The protocol must carry the sidecar's actual terminal +decision. + +An ACP-only `permission_expired` event would work for this one route but would +duplicate correlation in every product client and leave host-tool, JS bridge, +and future extension callbacks with the same transport gap. A deadline field on +`SidecarRequestFrame` would still make clients run policy timers and would be +subject to clock/scheduling skew. A generic terminal frame uses the request ID +the transports already own and keeps ACP clients ignorant of timeout policy. + +Do not add a cancellation request that itself needs a response. Once the +sidecar has removed its waiter, waiting for an acknowledgement would create a +second failure/timeout cycle. Ordered delivery on sidecar stdout is enough to +tell the trusted, same-version host transport to drop its corresponding route. + +## Exact current behavior + +### Native sidecar owns the real deadline + +`crates/agentos-sidecar/src/acp_extension.rs` defines: + +```rust +const PERMISSION_CALLBACK_TIMEOUT: Duration = Duration::from_secs(120); +const PERMISSION_CALLBACK_CLEANUP_GRACE: Duration = Duration::from_secs(5); +``` + +`build_inbound_response` around current lines 1540-1600 encodes an +`AcpPermissionCallback` with `cleanup_after_ms = 125_000`, registers an +`ExtensionCallbackCancellation`, and calls +`ExtensionSnapshot::invoke_callback_cancellable` with only the authoritative +120-second timeout. + +`permission_callback_reply_from_result` around current lines 2427-2442 maps +`SidecarError::Timeout` to the sidecar default (`"reject"`). The sidecar does +not wait for the extra five seconds and does not receive any signal from the +client to decide policy. + +### The native callback waiter already has the correct race point + +`FrameSidecarRequestTransport::send_request_inner` in +`crates/native-sidecar/src/stdio.rs:1735-1847` owns a pending map keyed by the +negative sidecar request ID. `accept_response` removes the same entry before it +sends the response to the waiter. + +On explicit extension cancellation, `send_request_inner` also removes that +entry and returns `"extension callback was cancelled"`. On timeout it removes +the entry and returns `SidecarError::Timeout`. A response received afterward is +unmatched: the stdin reader cannot claim it through `accept_response`, so it is +forwarded to the normal sidecar path and treated as a stale response. + +This pending-map removal is the linearization point. If removal returns the +sender, timeout/cancellation won and the sidecar must emit the cancellation +frame. If removal finds no sender, `accept_response` already won; the waiter +must receive that response and no cancellation frame may be emitted. + +There is one distributed race that the implementation and tests must describe +honestly. Sidecar stdout (request/cancellation) and host stdin (response) are +separate byte streams. A host may therefore enqueue a response just before the +sidecar removes the waiter, yet the sidecar may remove the waiter before its +stdin reader accepts those response bytes. A one-way cancellation frame cannot +retract that already-written frame and an unknown cancellation ID at the host +does **not** prove that the response won in the sidecar. The current fallback +through `NativeSidecar::accept_sidecar_response` safely classifies unmatched +responses as benign stale replies, so this race does not corrupt another route +or terminate the shared sidecar. + +Item 68 should guarantee that no reply is generated after the client observes +the terminal frame, and that both sides terminate their correlation once. It +must not claim that a frame already accepted by the host's writer can never +lose the authoritative sidecar race. If product requirements demand positive +proof that every submitted response was accepted, that needs a second +sidecar-to-host `accepted` acknowledgement (a larger protocol change), not a +client timer. + +The existing tests +`cancellable_sidecar_callback_wait_stops_without_waiting_for_its_deadline` and +`callback_response_and_cancellation_complete_wait_exactly_once` in +`crates/native-sidecar/src/stdio.rs` already cover the sidecar half of this +race. They currently prove that a deliberately late response is rejected, but +there is no frame telling the host not to send it. + +### TypeScript manufactures a later cleanup timer + +The generated ACP field is declared in +`crates/agentos-protocol/protocol/agent_os_acp_v1.bare:270-278` and generated +into `packages/core/src/sidecar/agentos-protocol.ts`. + +`AgentOs._handleAcpExtSidecarRequest` in +`packages/core/src/agent-os.ts:2850-2905` checks that `cleanupAfterMs` fits the +JavaScript number range and passes it to `_handleAcpPermissionCallback`. + +`_handleAcpPermissionCallback` at current lines 2908-2961 installs a +`setTimeout(cleanupAfterMs)`. Until it fires, the entry remains in +`AgentSessionEntry.pendingPermissionReplies`, so `respondPermission` can still +find a route after the sidecar has already selected its default. When the timer +finally rejects, the function logs and returns `undefined`; the protocol client +then writes an `ext_result` for a sidecar request whose waiter is gone. + +`packages/core/tests/session-config-routing.test.ts` currently codifies this: +`uses only the sidecar-owned post-decision cleanup deadline` advances a local +20 ms timer and proves the host route exists until that timer fires. Despite its +name, this is still a client timer over a sidecar-supplied duration. + +### Rust independently implements the same timer + +`PermissionRouteRequest` in `crates/client/src/session.rs:35-42` carries +`cleanup_after_ms`. `wait_for_permission_reply` at current lines 423-444 races +the pending reply and `PermissionResponder` against +`tokio::time::sleep(cleanup_after_ms)`. + +`AgentOs::deliver_sidecar_permission_request` at current lines 1698-1783 removes +the map entry only after `PendingPermissionOutcome::CleanupElapsed`. The unit +test `permission_reply_wait_uses_only_the_later_cleanup_deadline` proves that +local timer behavior. + +The callback decoder in `crates/client/src/agent_os.rs:1258-1320` simply copies +the generated field into `PermissionRouteRequest`.

If cancellation or +timeout happens before the request frame was written, remove the local waiter +but emit no cancellation frame because the host never received a route. + +Do not ignore cancellation-frame write failure. Propagate it as the existing +bridge/I/O failure so the host-visible transport path reports that terminal +correlation could not be delivered. + +The stdio transport's `pending` map is currently not protected by the service +tracker's 10,000-entry admission check. Bound it in this revision before making +host transports depend on it: reuse `MAX_PENDING_SIDECAR_RESPONSES`, make the +existing `sidecar_response_pending_overflow_error` available within the crate, +and have `FrameSidecarRequestTransport` observe the existing +`pending_sidecar_responses_gauge` on insert, response, cancellation, and write +failure. Pass that gauge from the `NativeSidecar` instance when constructing +the stdio callback transport. This reuses the sidecar-owned limit and its +near-threshold warning instead of copying a limit into each client. + +Update exhaustive frame-kind/host-input matches in `stdio.rs`. A +`SidecarRequestCancelledFrame` received from host stdin is invalid direction; +the native sidecar only writes this frame. + +No policy change belongs in `permission_callback_reply_from_result`: timeout +still maps to the ACP default and explicit lifecycle cancellation retains its +current enclosing-operation behavior. + +## Exact TypeScript transport edits + +### Live frame model and codec + +In `packages/runtime-core/src/protocol-frames.ts`: + +- add `LiveSidecarRequestCancelledFrame` with + `frame_type: "sidecar_request_cancelled"`, request ID, ownership, and the two + lowercase live reasons; +- include it in `LiveSidecarWrittenProtocolFrame` and the general live frame + union used by JSON tests; +- decode the generated frame and map the generated reason without + interpreting it; and +- classify it as a distinct control kind. + +In `packages/runtime-core/src/frame-rpc.ts`, extend `ClassifiedFrame` and +`FrameRpcTransport` with a sidecar-request-cancelled type/listener. Do not send +the frame through the normal event buffer; it is transport correlation, not a +public VM event. + +Add a protocol transport error in +`packages/runtime-core/src/sidecar-errors.ts`, for example +`SidecarRequestCancelled`, retaining request ID, ownership, and exact reason. +Use it as `AbortSignal.reason`; do not translate `DEADLINE_EXCEEDED` into ACP +policy or a permission answer. + +### Active inbound callback routes + +In `packages/runtime-core/src/protocol-client.ts`, add a map keyed by the +sidecar request ID whose value retains original ownership and an +`AbortController`. Its population is transitively bounded by the trusted +sidecar's `MAX_PENDING_SIDECAR_RESPONSES` admission limit (10,000) after the +stdio bound above is applied; duplicate live IDs are protocol errors, not +replacement opportunities. + +Extend `LiveSidecarRequestHandler` in `protocol-frames.ts` to receive a second +context argument: + +```ts +export interface LiveSidecarRequestContext { + readonly signal: AbortSignal; +} + +export type LiveSidecarRequestHandler = ( + request: LiveSidecarRequestFrame, + context: LiveSidecarRequestContext, +) => Promise | LiveSidecarResponsePayload; +``` + +Existing one-argument functions remain assignable in TypeScript. Pass the +context through `resolveSidecarRequestFramePayload`. + +`dispatchSidecarRequest` must: + +1. reject a duplicate active request ID; +2. install the route before invoking user/host code; +3. await the handler with its signal; +4. claim/remove the route before writing a response; and +5. suppress the response if a cancellation frame already removed that exact + route. + +The cancellation listener must verify exact ownership for a live ID, remove +the route once, and abort with `SidecarRequestCancelled`. An unknown ID is a +benign terminal race: the response may have won in the sidecar, or it may +already have entered the host writer and then lost to expiry before the +sidecar's stdin reader accepted it. Never interpret unknown as proof of +sidecar acceptance. Transport failure/disposal must abort every active +controller with the existing terminal error and clear the map so handler +promises do not retain correlation indefinitely. + +Do not add a timeout to `SidecarProtocolClient`; it consumes the sidecar's +terminal signal. + +## Exact Rust transport edits + +In `crates/sidecar-client/src/transport.rs`: + +- add `WireSidecarRequestContext`, carrying the request ID and a clonable + cancellation receiver/future; +- change `WireSidecarCallback` to receive `(payload, ownership, context)`; +- add an active inbound-callback map keyed by negative request ID with exact + ownership plus its cancellation sender; +- insert the route before spawning the callback; +- on callback completion, remove/claim the route before sending + `SidecarResponseFrame`; +- on `SidecarRequestCancelledFrame`, remove the exact route, verify ownership, + and resolve its context with the exact reason; and +- on reader failure/silence shutdown, terminate every active context before + clearing it. + +If cancellation won before callback output entered the writer, a callback +future may finish cooperatively but its task must not send a response. Unknown +cancellation IDs are benign terminal races, not necessarily response wins. Do +not publish cancellation through `control_event_log`; permission and other +callback routes consume it directly. + +Update the three callback factories in `crates/client/src/agent_os.rs` +(`js_bridge_call_callback`, `permission_request_callback`, and +`host_callback_callback`) for the context parameter. Only the permission path +needs to await cancellation in Item 68. Passing a context to the other paths is +the generic transport contract and allows later host APIs to support +cooperative cancellation without another wire change; do not redesign their +public callback APIs here. + +Re-export the context beside `WireSidecarCallback` from +`crates/client/src/transport.rs` if the current private transport import path +requires it. No new Tokio utility dependency is needed; the crate already uses +Tokio channels. + +## Remove the ACP cleanup duration + +### Shared ACP callback schema + +Delete `cleanupAfterMs` from `AcpPermissionCallback` in +`crates/agentos-protocol/protocol/agent_os_acp_v1.bare`.

The item removes a client bookkeeping +duration, not the authoritative deadline. + +### TypeScript AgentOS client + +Stack this item after Item 67 because both edit +`AgentOs._handleAcpPermissionCallback`. Preserve Item 67's explicit fail-fast +handler delivery and immediate local-failure cleanup. + +In `packages/core/src/agent-os.ts`: + +1. remove `cleanupTimer` from `AgentSessionEntry.pendingPermissionReplies`; +2. remove timer clearing from session-close/dispose and `respondPermission`; +3. have the registered sidecar request handler pass its + `LiveSidecarRequestContext.signal` through `_handleAcpExtSidecarRequest` to + `_handleAcpPermissionCallback`; +4. delete the `cleanupAfterMs` safe-integer check and method parameters; +5. register one abort listener for the exact pending entry; when it fires, + remove that entry and settle the local callback as `undefined` without + selecting a permission reply; and +6. remove the abort listener in `finally` on explicit reply, handler failure, + session close, or cancellation. + +Use identity when deleting from the map so an old cancellation cannot remove a +new route that reused the same permission ID. Check `signal.aborted` before and +immediately after listener installation so a cancellation that arrived during +callback decoding cannot be missed. Normal sidecar timeout is expected +control flow and should not create a second client warning; the sidecar already +logs that it applied its default. + +After Item 67, handler invocation must remain outside the promise constructor. +Its synchronous-failure branch should delete the route and return `undefined`, +but it no longer has a timer to clear. Do not reintroduce incidental +promise-executor exception behavior while wiring the abort signal. + +Update fixture shapes in: + +- `packages/core/tests/agent-os-dispose-retry.test.ts`; +- `packages/core/tests/session-config-routing.test.ts`; +- `packages/core/tests/permission-no-handler-warning.test.ts` where its helper + signature names the duration; +- `packages/core/tests/cross-session-permission-reply.test.ts`; and +- Item 67's `permission-handler-failure.test.ts` if that revision has landed. + +Some fixtures use their own structural pending-reply type rather than the +production interface. Remove only timer-specific fields/assertions; retain +session isolation, close rejection, and exact reply ownership tests. + +### Rust AgentOS client + +In `crates/client/src/session.rs`: + +- replace `PermissionRouteRequest.cleanup_after_ms` with the generic wire + callback cancellation context; +- replace `PendingPermissionOutcome::CleanupElapsed` with `Cancelled`; +- have `wait_for_permission_reply` select the pending reply, responder reply, + or the context's cancellation future—never a sleep; +- on cancellation, remove the exact pending sender and return no reply; and +- update `PermissionRequest` documentation to say the route ends from the + sidecar signal. + +In `crates/client/src/agent_os.rs`, pass the `WireSidecarRequestContext` from +`permission_request_callback` through `handle_acp_ext_callback` and +`route_permission_request`. Remove `callback.cleanup_after_ms` and the field in +the malformed-callback test struct literal around current line 2257. + +Do not add a Rust duration constant, sleep, or cancellation-to-`Reject` mapping. +The Rust client returns `reply: None`; the sidecar alone converts its own timeout +to the default. + +## Before and after tests + +### Before evidence + +Use the existing tests as the vulnerable-parent characterization: + +- `packages/core/tests/session-config-routing.test.ts` — + `uses only the sidecar-owned post-decision cleanup deadline` proves the TS + route stays live until its client timer; +- `crates/client/src/session.rs` — + `permission_reply_wait_uses_only_the_later_cleanup_deadline` proves Rust does + the same; +- `crates/native-sidecar/src/stdio.rs` — + `cancellable_sidecar_callback_wait_stops_without_waiting_for_its_deadline` + proves the sidecar waiter is already gone while no terminal frame is emitted; + and +- `callback_response_and_cancellation_complete_wait_exactly_once` proves a + deliberately late response is rejected after cancellation wins. + +Extend the native test on the parent just enough to record that the stdout +channel contains the original `SidecarRequestFrame` and no second terminal +frame after cancellation. That is the exact missing protocol behavior. + +### Protocol codec tests + +In `crates/sidecar-protocol`, round-trip both cancellation reasons and assert +request ID/ownership preservation in BARE and JSON compatibility tests. + +In `packages/runtime-core/tests/protocol-frames.test.ts`, round-trip/decode a +`sidecar_request_cancelled` frame and assert exact live reason mapping. Extend +`packages/runtime-core/tests/frame-rpc.test.ts` so the new classified kind +reaches only its cancellation listeners and counts as frame activity. + +### Native sidecar race tests + +Extend the existing stdio tests instead of adding a 120-second ACP test: + +1. a short callback timeout emits exactly one cancellation frame with the same + request ID/ownership and `DEADLINE_EXCEEDED`; +2. `ExtensionCallbackCancellation::cancel()` emits exactly one frame with + `CANCELLED` without waiting for the deadline; +3. when `accept_response` wins, no cancellation frame is emitted; and +4. when cancellation wins, a late response cannot claim the waiter. + +This tests the same transport used by the 120-second permission callback while +keeping the default suite fast. + +### TypeScript runtime transport tests + +In `packages/runtime-core/tests/protocol-client.test.ts`: + +- register a handler that records its context and waits for `signal.abort`; +- inject a sidecar request followed by a matching cancellation frame; +- assert `signal.reason` is the structured cancellation error with exact ID, + ownership, and reason; +- assert the active route is removed and no `sidecar_response` is written even + if the handler later resolves; and +- cover the opposite race: a completed handler writes one response and a later + cancellation does not abort a new/reused route or write a second frame. + +Add ownership-mismatch and transport-dispose cases. Update the explicit +sidecar-written frame unions in +`packages/runtime-core/tests/shared-sidecar-ownership.test.ts`, and add an +ownership-routing assertion proving cancellation for VM A cannot terminate VM +B's live callback. Do not use a timeout in these tests; direct frame injection +proves the client consumes sidecar state. + +### Rust transport tests + +In the `crates/sidecar-client/src/transport.rs` test module: + +- register a callback that waits on its `WireSidecarRequestContext`; +- feed a sidecar request and then a cancellation frame through + `handle_wire_frame`; +- assert exact reason, zero active inbound routes, and no control response; +- assert a response-completion winner sends exactly one response and a later + cancellation is harmless; and +- assert `fail_all_pending` resolves active callback contexts. + +Retain the existing bounded writer and pending host-request tests. + +### Product-client permission tests + +Rewrite the TypeScript fake-timer test in +`packages/core/tests/session-config-routing.test.ts` to pass an `AbortSignal`: + +- before abort, the permission route is pending; +- sidecar cancellation immediately removes it; +- `respondPermission` then reports `Permission request is not pending`; +- the callback returns `undefined`; and +- `vi.getTimerCount()` remains zero throughout. + +Keep Item 67's synchronous handler-failure tests green and update them to prove +there is no delayed timer side effect. + +Replace Rust's cleanup-deadline test with +`permission_reply_wait_ends_on_sidecar_cancellation`. Trigger the context +without sleeping and assert the pending sender is removed, the retained +`PermissionResponder` observes its receiver close, and a late reply cannot be +bridged. + +Retain `missing_client_permission_reply_uses_sidecar_default` and +`only_callback_timeout_uses_sidecar_permission_default` in +`crates/agentos-sidecar/src/acp_extension.rs`; they prove cancellation of host +bookkeeping does not move default policy into either client. + +## Risks and dependencies + +- **Exact race ownership is essential.** Timeout/cancellation may emit a frame + only after it successfully removes the pending waiter. Response-win must emit + no cancellation. Test both orders repeatedly or with explicit barriers. +- **Do not overstate the cross-stream guarantee.** Once response bytes enter a + host writer they cannot be retracted by a later stdout cancellation frame. + The required guarantee is no newly generated response after observed + cancellation plus benign handling of an already-in-flight loser. A positive + response-acceptance guarantee would require a separate acknowledgement. +- **Do not buffer cancellation as an event.** Callback correlation must not + compete with bounded user event history or event subscribers. +- **Do not reuse request IDs while active.** The sidecar already allocates + decreasing negative IDs. Clients should reject a duplicate active ID and use + entry identity when removing routes. +- **Cancellation is not a permission answer.** Both clients return no reply; + only the sidecar timeout path chooses the ACP default. +- **Transport shutdown must drain routes.** Adding active callback maps without + aborting them in failure/dispose paths would replace a five-second leak with + an unbounded one. +- **The active maps must be bounded by the sidecar.** The compatibility service + already rejects more than 10,000 pending sidecar responses, but the live + `FrameSidecarRequestTransport` does not currently apply that check. Extend the + same sidecar-owned bound/gauge to the live transport, then keep both host maps + one-for-one with emitted requests and retain no completed tombstones. +- **Item 67 should land first.** Item 68 removes its timer but must preserve its + fail-fast handler contract and local exception cleanup. Resolve the shared + `agent-os.ts` test edits in the Item 68 revision rather than recombining the + work. +- **Item 52 is adjacent.** It removes false permission detection from session + notifications but retains the typed reverse callback. Land it before this + item if it still edits the callback decoder area. +- **Item 56 may reuse the generic primitive.** Reliable cron callback delivery + can consume the cancellation context later, but cursor/ack semantics remain + Item 56. Do not add cron frames or state here. +- **Other host callbacks are not redesigned.** JS bridge/tool callback APIs may + ignore the new signal initially; transport response suppression still works. + Cooperative abortion of arbitrary user work needs a separate public API + decision. +- **No browser-adapter policy fork.** `agentos-native-sidecar-browser` does not + currently originate this native ACP permission callback. It needs no timeout + implementation. The shared generated frame and runtime-core transport remain + usable by injected/browser transports without an ACP-specific branch. +- **No new dependency is needed.** Use existing `AbortController` and Tokio + channel primitives; avoid adding a cancellation library and lockfile churn. + +## Dedicated `jj` revision boundary + +Create one dedicated stacked revision, for example +`feat(protocol): cancel expired sidecar callbacks`, containing only: + +```text +crates/sidecar-protocol/protocol/agentos_sidecar_v1.bare +crates/sidecar-protocol/src/{protocol.rs,wire.rs} +crates/native-sidecar/src/{service.rs,stdio.rs} +crates/native-sidecar/tests/protocol.rs +crates/sidecar-client/src/transport.rs + +packages/runtime-core/src/{generated-protocol.ts,frame-rpc.ts,protocol-frames.ts,protocol-client.ts,sidecar-errors.ts} +packages/runtime-core/tests/{frame-rpc.test.ts,protocol-frames.test.ts,protocol-client.test.ts,shared-sidecar-ownership.test.ts} + +crates/agentos-protocol/protocol/agent_os_acp_v1.bare +crates/agentos-sidecar/src/acp_extension.rs +crates/agentos-sidecar/tests/acp_extension.rs +crates/client/src/{agent_os.rs,session.rs,transport.rs} + +packages/core/src/agent-os.ts +packages/core/src/sidecar/agentos-protocol.ts +packages/core/tests/session-config-routing.test.ts +packages/core/tests/agent-os-dispose-retry.test.ts +packages/core/tests/permission-no-handler-warning.test.ts +packages/core/tests/cross-session-permission-reply.test.ts +packages/core/tests/permission-handler-failure.test.ts # if Item 67 landed + +docs/thin-client-migration.md +``` + +Generated Rust wire/ACP code remains build output.

Use one small internal dispatch helper so the public `AgentOs` subscriber +sets and the native proxy use the same behavior. + +Delete the proxy's synthetic delivery of an event-pump error to every process's +stderr listeners. A transport failure is not guest stderr and should reject the +affected process waits with its original error after one host-visible pump +diagnostic. + +Priority: **P1**. Confidence: **high**. + +This behavior must remain in TypeScript. A stdout/stderr callback is an arbitrary +function in the trusted host JavaScript process; the sidecar cannot invoke, +catch, identify, or log that function's exception. The sidecar already does its +only required job here: it emits ordered `process_output` and terminal +`process_exited` events. No Rust, protocol, sidecar, or generated-code change is +needed. + +## Original issue and exact failure path + +The tracker entries are at `docs/thin-client-migration.md:115,196,282`: + +> A TypeScript process output handler can throw through the shared sidecar event +> pump, fail unrelated live process routes, and stop later event delivery. + +`NativeSidecarKernelProxy.runEventPump` in +`packages/core/src/sidecar/rpc-client.ts:806-879` waits for one VM-owned event at +a time. Its `process_output` branch invokes listeners without an isolation +boundary: + +```ts +const listeners = + event.payload.channel === "stdout" ? entry.onStdout : entry.onStderr; +for (const listener of listeners) { + listener(chunk); +} +``` + +A synchronous listener exception therefore reaches the method's outer `catch`. +That catch assigns the callback exception to `pumpError`, sends its message to +every live route as fabricated stderr, rejects all those process waits, and +returns permanently: + +```ts +this.pumpError = error instanceof Error ? error : new Error(String(error)); +for (const entry of this.trackedProcesses.values()) { + const stderr = new TextEncoder().encode(`${this.pumpError.message}\n`); + for (const listener of entry.onStderr) { + listener(stderr); + } + this.failProcess(entry, this.pumpError); +} +return; +``` + +The stderr fan-out is itself unguarded. A second throwing stderr handler can +interrupt the failure loop before some entries are settled, leaving the event +pump rejected and those routes live without future delivery. + +The scope is precise: each `NativeSidecarKernelProxy` pump is filtered to one +`vmId`, even when several VMs share one native sidecar process. The defect fails +all live process routes in the same proxy/VM. It does not directly stop the +separate proxy pump for another VM. + +There is a second fan-out above the proxy. `AgentOs.spawn` in +`packages/core/src/agent-os.ts:1712-1742` gives the proxy one wrapper per channel, +and those wrappers synchronously iterate the public subscriber sets: + +```ts +onStdout: (data) => { + for (const h of stdoutHandlers) h(data); +}, +onStderr: (data) => { + for (const h of stderrHandlers) h(data); +}, +``` + +Even if the proxy catches that wrapper's exception, the first throwing public +subscriber still prevents later subscribers from seeing the same chunk. Both +fan-outs must use per-handler isolation to satisfy the tracker; changing only +`runEventPump` is incomplete. + +`NativeSidecarKernelProxy.openShell` has another small wrapper fan-out at +`packages/core/src/sidecar/rpc-client.ts:535-558`. It currently contains one +mutable stdout `onData` callback and at most one initial stderr callback, so it +has no sibling-delivery defect of its own. The lower proxy dispatch boundary +still catches and reports either callback if it throws. Do not add a third +shell-specific mechanism. + +## Cross-language, protocol, and generated-surface audit + +| Layer | Exact current surface | Item 69 disposition | +|---|---|---| +| Sidecar schema | `crates/sidecar-protocol/protocol/agentos_sidecar_v1.bare:958-997` defines ordered `ProcessOutputEvent` and `ProcessExitedEvent` payloads. | No edit. A host callback exception is not a guest event and must not be sent over this protocol. | +| Generated TypeScript | `packages/runtime-core/src/generated-protocol.ts:4827-4982` contains the generated process-event codec/union. | No regeneration or hand edit. The wire event remains unchanged. | +| Rust protocol compatibility | `crates/sidecar-protocol/src/protocol.rs:1015-1068,1458-1465` maps the same process payloads without callback semantics. | No edit. | +| Native sidecar | `crates/native-sidecar/src/execution.rs:5468-5596` emits stdout/stderr chunks before the terminal event. | No edit.

The sidecar continues to own process state and output ordering; +the client merely prevents arbitrary trusted-host observer code from corrupting +its transport loop. + +## Exact production edits + +### 1. Add `packages/core/src/process-output-handlers.ts` + +Add one internal helper; do not export it from the package root and do not add a +new client option or policy surface. + +```ts +export type ProcessOutputChannel = "stdout" | "stderr"; + +export interface ProcessOutputHandlerContext { + channel: ProcessOutputChannel; + pid?: number; + processId?: string; +} + +function reportProcessOutputHandlerFailure( + error: unknown, + context: ProcessOutputHandlerContext, +): void { + console.error("[agent-os] process output handler failed", { + error, + channel: context.channel, + ...(context.pid !== undefined ? { pid: context.pid } : {}), + ...(context.processId !== undefined + ? { processId: context.processId } + : {}), + }); +} + +export function dispatchProcessOutputHandlers( + handlers: Iterable<(data: Uint8Array) => void>, + data: Uint8Array, + context: ProcessOutputHandlerContext, +): void { + for (const handler of handlers) { + try { + handler(data); + } catch (error) { + reportProcessOutputHandlerFailure(error, context); + } + } +} +``` + +The diagnostic deliberately excludes the chunk. Process output can be large or +contain caller/guest secrets; channel and route identity are enough to locate +the failed callback. Keep the thrown value unchanged in the structured record +so non-`Error` throws are not silently normalized away. + +The declared callback contract is synchronous `void`, so the required Item 69 +fix is the `try/catch` above. If rejected async functions are intentionally +accepted later, attach a rejection observer without awaiting it; never stall the +ordered event pump on host callback work. Do not broaden this revision merely +to define asynchronous callback semantics. + +### 2. Update `packages/core/src/sidecar/rpc-client.ts` + +Import it with: + +```ts +import { dispatchProcessOutputHandlers } from "../process-output-handlers.js"; +``` + +In the `process_output` branch of +`NativeSidecarKernelProxy.runEventPump`, replace the raw listener loop with: + +```ts +dispatchProcessOutputHandlers(listeners, chunk, { + channel: event.payload.channel, + processId: event.payload.process_id, + ...(entry.pid !== null ? { pid: entry.pid } : {}), +}); +``` + +This keeps listener invocation synchronous and in set insertion order while +ensuring one failure cannot be mistaken for a transport failure. + +In the outer `catch`, distinguish a genuine wait/transport failure from a host +callback failure (callbacks no longer reach it), log once, fail every live route +with the exact same error object, and remove the synthetic stderr fan-out: + +```ts +const pumpError = error instanceof Error ? error : new Error(String(error)); +this.pumpError = pumpError; +console.error("[agent-os] sidecar process event pump failed", { + error: pumpError, + vmId, +}); +for (const entry of [...this.trackedProcesses.values()]) { + if (!entry.settled) { + this.failProcess(entry, pumpError); + } +} +return; +``` + +Use `entry.settled`, not `entry.exitCode !== null`: a failed entry can be settled +while retaining a null exit code. Snapshotting the map is defensive because +`failProcess` deletes entries from both tracking maps. + +Do not rethrow, terminate a process, synthesize an exit code, inject the callback +message into guest stderr, or send a callback-result RPC. A failed observer does +not change process state. A genuine pump failure already reaches callers through +the rejected `ManagedProcess.wait()`/exec promise. + +### 3. Update `packages/core/src/agent-os.ts` + +Import the same helper with: + +```ts +import { dispatchProcessOutputHandlers } from "./process-output-handlers.js"; +``` + +In `AgentOs.spawn`, declare +`let processPid: number | undefined` immediately before calling +`this.#kernel.spawn`, replace both raw public-handler loops, then assign +`processPid = proc.pid` after the awaited spawn returns: + +```ts +let processPid: number | undefined; +const proc = await this.#kernel.spawn(command, args, { + ...options, + onStdout: (data) => { + dispatchProcessOutputHandlers(stdoutHandlers, data, { + channel: "stdout", + ...(processPid !== undefined ? { pid: processPid } : {}), + }); + }, + onStderr: (data) => { + dispatchProcessOutputHandlers(stderrHandlers, data, { + channel: "stderr", + ...(processPid !== undefined ? { pid: processPid } : {}), + }); + }, +}); +processPid = proc.pid; +``` + +This is the isolation point that lets a later `onProcessStdout` or +`onProcessStderr` subscriber receive the same chunk after an earlier subscriber +throws. PID is optional because a nonstandard kernel could synchronously emit +output before its spawn promise resolves; output isolation must not depend on +that correlation being available. The lower proxy helper remains necessary for +direct kernel `exec`, `execArgv`, `openShell`, and other internal callers that do +not pass through these public sets. + +Do not delete a throwing subscriber automatically. JavaScript event APIs do not +normally unsubscribe a listener because it threw, and automatic removal would +add client-owned retry/lifecycle policy. A repeatedly failing callback produces +one diagnostic per invocation until its owner calls the existing unsubscribe +function. + +### 4. Update the public process documentation + +After the process `` in +`website/src/content/docs/docs/core.mdx:52-56`, add one behavioral sentence: + +```mdx +Process output callbacks are isolated observers. If one throws, AgentOS reports +the host callback failure and continues delivering ordered output to the other +listeners without changing the guest process. +``` + +This is a public callback-contract change. It needs documentation, but no new +option, exported type, or runnable example. + +## Focused before/after tests + +### Low-level pump and sibling-process regression + +Extend `packages/core/tests/process-event-ordering.test.ts` because it already +drives the real `NativeSidecarKernelProxy.runEventPump` with a deterministic +queued client. + +First make `createStubClient().execute()` return unique process IDs/PIDs while +preserving the existing first values: + +```ts +let processSequence = 0; +async execute() { + processSequence += 1; + return { + processId: `process-${processSequence}`, + pid: 4241 + processSequence, + }; +} +``` + +Also give the deterministic client an explicit pump-rejection seam rather than +reaching into proxy internals. Change the queue to a result union and have the +existing `deliver` closure resolve or reject the pending wait: + +```ts +type PumpResult = { event: PumpEvent } | { error: Error }; +const queue: PumpResult[] = []; + +// Inside deliver(): +const result = queue.shift(); +if (!result) return false; +if ("error" in result) reject(result.error); +else resolve(result.event); +return true; + +// Returned test controls: +pushEvent(event: PumpEvent) { + queue.push({ event }); + notify?.(); +}, +failPump(error: Error) { + queue.push({ error }); + notify?.(); +}, +``` + +Keep the existing `notify` reset after any delivered result, and make the abort +listener `{ once: true }`. This makes the real-pump-failure case deterministic +without exposing a test-only production method. + +Add a table-driven test for both `stdout` and `stderr`: + +1. spawn two processes on the same proxy; +2. give process 1 a channel callback that throws `handlerFailure` only on its + first invocation; +3. attach resolved expectations to both `wait()` promises before emitting; +4. push process 1 output, later process 1 output, process 2 output, and ordered + terminal events for both; +5. assert both waits resolve with their own exit codes, process 1 receives its + later event, and process 2 receives its exact output in order; and +6. spy on `console.error` and assert exactly one + `"[agent-os] process output handler failed"` record containing the original + thrown object, channel, `pid: 4242`, and `processId: "process-1"`. + +Against current code this test proves the **before** behavior: both process waits +reject with `handlerFailure`, later queued output is starved, and no structured +callback diagnostic is emitted. With the fix it proves the **after** behavior +and confirms the pump remains live. + +Add a separate real-pump-failure case to the same file: make the stub's next +`waitForEvent` reject with a distinctive transport error while two processes +are live. Assert one structured pump diagnostic, both waits reject with the +same error object, and neither stderr callback receives fabricated bytes. This +locks in removal of the non-Linux synthetic stderr behavior. + +### Public sibling-handler regression + +Extend `packages/core/tests/leak-agent-os-processes.test.ts`, reusing its minimal +private-constructor `AgentOs` fixture. Supply a mock kernel whose `spawn` captures +the forwarded `onStdout`/`onStderr` wrapper and returns a controllable +`ManagedProcess`. For each channel: + +1. pass a throwing callback in `vm.spawn(..., { onStdout/onStderr })`; +2. add a second callback with `vm.onProcessStdout`/`onProcessStderr`; +3. invoke the captured kernel callback with one exact `Uint8Array`; +4. assert invocation does not throw, the second callback receives the same + buffer object, and the structured error contains the original exception and + channel; and +5. unsubscribe/settle the mock process so cleanup remains deterministic. + +This fails before the `AgentOs.spawn` edit because the first callback throws +through the wrapper and the second callback is skipped. It prevents an +implementation that fixes only the low-level pump but still violates the +public subscriber contract. + +The exact fixture change is to add an optional kernel override without altering +the existing seven private-constructor arguments: + +```ts +function makeAgentOs( + processRouteRetention = 1_024, + kernelOverrides: Record = {}, +) { + const kernelMock = { + dispose: async () => {}, + ...kernelOverrides, + }; + // Existing constructor setup remains unchanged. +} +``` + +For the new test, use `makeProc` so `wait()` stays pending while the captured +output wrapper is invoked. The kernel override's `spawn` stores the forwarded +options and returns that process. Resolve the process afterward, await its +terminal correlation, restore the console spy, and call `vm.dispose()` in +`finally`. Assert the structured diagnostic includes `pid` once `vm.spawn` has +returned. + +No test moves to Rust or the sidecar. Neither environment can create a throwing +host JavaScript callback. Existing sidecar process-event ordering tests remain +the authority for output-before-exit wire behavior. + +## Dependencies, risks, and non-goals + +- **Item 54 is separate:** its `SidecarProtocolClient.dispatchEvent` listener + warning protects direct transport subscribers.

Rebase the queue/unique-ID changes onto its final helper; + do not restore removed client-side stdin sequencing. +- **Items 57 and 70 may touch process-route tests/state:** preserve their + terminal-route and cache changes. Item 69 owns callback dispatch only. +- **Mutation during dispatch:** JavaScript `Set` iteration has live mutation + semantics. Keep the current direct iteration; do not snapshot or redefine + subscribe/unsubscribe-during-callback behavior in this item. +- **Output ordering:** do not defer callbacks with `queueMicrotask`, promises, + or a side queue. Catching synchronously preserves sidecar event order. +- **No callback-to-sidecar protocol:** reporting an exception to the sidecar + would falsely make a host observer part of process execution and could let a + UI/listener failure affect guest state. +- **No new public error class:** Item 63 owns exported operation errors. A small + structured log record is sufficient here and avoids expanding the client API. +- **Item 74 owns post-failure starts:** after a genuine pump failure, + `startTrackedProcess` does not currently consult `pumpError`, so a later spawn + can start without a live event consumer.

That is the +only process-retention policy Item 70 should preserve. + +The browser sidecar implements the same wire request from its own live kernel +state. Do not change native/browser process semantics in this TypeScript cache +deletion. + +## Exact production edits + +### `packages/core/src/sidecar/rpc-client.ts` + +1. Delete the field: + + ```ts + readonly processes = new Map(); + ``` + +2. Simplify `buildProcessSnapshot` to a direct translation plus the existing PID + sort: + + ```ts + private buildProcessSnapshot( + snapshot: SidecarProcessSnapshotEntry[], + ): ProcessInfo[] { + return snapshot + .map((entry) => ({ + pid: entry.pid, + ppid: entry.ppid, + pgid: entry.pgid, + sid: entry.sid, + driver: entry.driver, + command: entry.command, + args: entry.args, + cwd: entry.cwd, + status: entry.status, + exitCode: entry.exitCode, + startTime: entry.startTime, + exitTime: entry.exitTime, + })) + .sort((left, right) => left.pid - right.pid); + } + ``` + + This also removes the transient `processMap`, which was silently + deduplicating duplicate PIDs. PID uniqueness is a sidecar/kernel invariant; + the client should not hide a malformed snapshot with an independent + last-entry-wins policy. + +3. Keep `snapshotProcesses`, `processSnapshotById`, and + `refreshProcessSnapshot` unchanged. In particular, retain the `finally` that + resets `processSnapshotRefresh` after each in-flight request. + +Do not touch `trackedProcesses`, `trackedProcessesById`, their bounded terminal +cleanup, or output listener sets. They route process handles/events and do not +duplicate the public sidecar snapshot. + +Update the comment in `finishProcess` at current lines 895-898 so it no longer +says the exited record lives in the deleted client `processes` map. State that +the exited record remains in the **sidecar-owned bounded process snapshot** for +late listing. This is a comment-only correction; do not retain a client table to +make the old wording true. + +### `packages/core/src/runtime.ts` + +Replace the legacy synchronous map in `Kernel`: + +```ts +readonly processes: ReadonlyMap; +``` + +with the authoritative asynchronous query already implemented by the native +proxy: + +```ts +snapshotProcesses(): Promise; +``` + +This makes the internal type express the real transport boundary. +`getAgentOsKernel()` is exposed only through the package's `./test/runtime` +entrypoint, so leaving `processes` in the interface after deleting the runtime +field would still promise repo integration tests a property that is `undefined` +at runtime. No root public export change is required. + +Do not add both members or mark `processes` optional. Either choice preserves a +tempting stale fallback and weakens compile-time enforcement of the thin-client +contract. + +### `packages/core/src/agent-os.ts` + +Replace the entire conditional in `allProcesses` with: + +```ts +async allProcesses(): Promise { + return await this.#kernel.snapshotProcesses(); +} +``` + +This keeps errors from `get_process_snapshot` visible to the caller. Do not +catch them and return an empty array or host-route state. `listProcesses` and +`getProcess` should continue to delegate through `allProcesses` without +additional changes. Item 41 removes `processTree` earlier in the stack; do not +reintroduce it here. + +No production sidecar, protocol, runtime-core, Rust-client, actor, or browser +edit is needed. + +## Before and after tests + +Add `packages/core/tests/process-snapshot-forwarding.test.ts` with a stub +`SidecarProcess`, using the same lightweight proxy construction and abortable +`waitForEvent` pattern as `leak-rpc-client.test.ts` and +`process-event-ordering.test.ts`. + +Use snapshot entries with distinct PIDs and every field populated so conversion +and sorting remain covered. Always dispose the proxy in `finally` so its event +pump is aborted. + +### Before-behavior source/heap evidence + +On the vulnerable parent, have `getProcessSnapshot` return a large deterministic +array (for example 4,096 entries), call `snapshotProcesses`, then assert: + +```ts +expect(proxy.processes.size).toBe(4_096); +expect([...proxy.processes.values()]).toEqual(returnedSnapshot); +``` + +Also assert corresponding objects by identity. This proves the proxy retains +one map node/key/reference for every returned object after the request has +finished, despite the caller using only the returned array. Record the focused +passing command and vulnerable revision in the tracker. Do not keep an +artificial memory-heavy test in the final suite. + +### After: no persistent cache and exact forwarding + +The lasting focused test should: + +1. return two unsorted complete entries from `getProcessSnapshot`; +2. call `proxy.snapshotProcesses()`; +3. assert `getProcessSnapshot` received the exact session and VM handles once; +4. assert the returned `ProcessInfo[]` contains every field and is sorted by + PID, preserving current public behavior; and +5. assert `Object.hasOwn(proxy, "processes")` is `false`. + +Add a type assertion that `Kernel` has `snapshotProcesses` and no `processes` +member, importing the internal type directly from `../src/runtime.js`. For +example, assert that `"snapshotProcesses" extends keyof Kernel` is `true` and +`"processes" extends keyof Kernel` is `false`. `packages/core` type-checking +must fail if the old map is reintroduced as the interface fallback. + +### After: snapshots remain live, not cached + +Have the stub return snapshot A on the first call and a different snapshot B on +the second sequential call. Assert: + +- `getProcessSnapshot` was called twice; +- the second result contains only B; and +- no property on the proxy retains A as a process table. + +Add one concurrent call case for `snapshotProcesses()` and +`processSnapshotById()` with a deferred stub response. Assert they share one +`getProcessSnapshot` call while it is in flight, then a subsequent call issues a +second request. This protects the useful `processSnapshotRefresh` single-flight +behavior from being mistaken for the removed persistent cache. + +### Retain public integration coverage + +Run, without rewriting: + +- `packages/core/tests/process-management.test.ts` for `listProcesses` and + `getProcess` against real sidecar snapshots; +- `packages/core/tests/all-processes.test.ts` for all-runtime process snapshots + and parent/child relationships; +- `packages/core/tests/session-cleanup.test.ts` for direct sidecar inspection; + and +- the sidecar process-snapshot tests in + `packages/core/tests/native-sidecar-process.test.ts`. + +Do not move snapshot construction or retention tests out of the sidecar.

The snapshot handler at +`execution.rs:4321-4348` returns live process trees plus that retained FIFO. + +The TypeScript `_processes` map, however, contains only public `AgentOs.spawn` +routes. `_pruneCompletedProcessRoutes` in +`packages/core/src/agent-os.ts:1628-1644` retains that many completed public +routes. Rust does the same for SDK spawn routes in +`crates/client/src/process.rs:1140-1182`. + +Therefore 1,024 unrelated finite exec/shell/ACP completions can evict an older +public-spawn snapshot even though the TypeScript/Rust public-spawn map has seen +little or no pressure and still retains that PID.

Consequently +`BrowserSidecar::process_snapshot_entries` at `service.rs:1614-1630` can return +only active executions. The wire `get_process_snapshot` handler at +`wire_dispatch.rs:1088-1119` has no terminal records to append. + +There is one adjacent parity prerequisite in the same browser route: its +`process_started_response` at `wire_dispatch.rs:2094` currently sends +`pid: None`, even though the service's active snapshot already contains the +kernel PID. Both TypeScript and Rust `spawn` reject an execute response without +a PID, so browser late-process and late-shell retention cannot be exercised +through the normal clients until this response forwards the sidecar PID. + +This contradicts the browser's advertised `process_route_retention` (1,024 by +default) and breaks late shell behavior. Both TypeScript `waitShell` / +`closeShell` and Rust `wait_shell` / `close_shell` query the sidecar snapshot by +process ID after their live shell route is gone. Native can resolve a retained +exit; browser reports the same known shell as missing immediately after exit. + +## Protocol contract + +### `crates/sidecar-protocol/protocol/agentos_sidecar_v1.bare` + +Replace the void request with presence-aware expectations and add explicit +unavailable lists to the existing response: + +```bare +type GetProcessSnapshotRequest struct { + expectedPids: optional> + expectedProcessIds: optional> +} + +type ProcessSnapshotResponse struct { + processes: list + unavailablePids: list + unavailableProcessIds: list +} +``` + +Semantics: + +- both expectation fields omitted means an ordinary authoritative diagnostic + snapshot and both unavailable lists must be empty; +- each present key is a caller assertion that the process was previously + returned by this VM; +- a key present in active or retained terminal state appears in `processes` and + not in an unavailable list; +- a key no longer present appears in the matching unavailable list; and +- each expected key must appear exactly once across `processes` and its + unavailable list. + +The response remains a full active-plus-retained snapshot; expectations classify +missing correlation and are not a client-selected history filter. This lets +`allProcesses` preserve its current diagnostic result while `listProcesses`, +`getProcess`, and late shell lookups obtain an explicit expiry signal. Item 41 +removes `processTree` earlier in the numbered stack; do not reintroduce it here. + +Use optional request fields so ordinary diagnostic callers preserve omission. +Do not make clients fill empty arrays as defaults. Reject duplicate keys, +invalid process IDs, and an expectation count above a sidecar-owned bound. The +bound should be derived in `native-sidecar-core` as: + +```text +process_route_retention(limits) + limits.resources.max_processes +``` + +with checked/saturating arithmetic and the normal default max-process value when +the optional kernel field is absent. The typed limit error must name the +observed count, capacity, and `limits.resources.maxProcesses` as the way to +raise it. The request list is trusted client input but still must not create an +unbounded allocation or quadratic duplicate scan; validate with sets. + +Have the shared classifier return a typed error enum, not a message-only +`SidecarCoreError`: invalid or duplicate keys and zero PIDs map to +`invalid_request`, while an expectation count above the derived capacity maps +to `limit_exceeded` in both native and browser adapters. The over-limit variant +must retain observed count, capacity, and the configuration path so neither +adapter has to parse text. + +When a request reaches the repository's standard near-limit threshold, emit a +structured `tracing::warn!` from each adapter with the VM ID, observed count, +capacity, and configuration path before classification. Add a shared threshold +predicate test so native and browser warning behavior cannot drift. The hard +failure remains the typed `limit_exceeded` response. + +This repository ships protocol, clients, and sidecars in lockstep, so changing +the existing request encoding is acceptable. Do not add compatibility decoding +for the old void payload. + +### Generated and live TypeScript shapes + +Regenerate `packages/runtime-core/src/generated-protocol.ts` with: + +```sh +pnpm --dir packages/build-tools build:protocol +``` + +Update `packages/runtime-core/src/request-payloads.ts` so +`get_process_snapshot` carries optional `expected_pids` and +`expected_process_ids`, preserving omission as generated `null`. Update +`packages/runtime-core/src/response-payloads.ts` so `process_snapshot` includes +safe-number-converted `unavailable_pids` and exact +`unavailable_process_ids`. + +Update the hand-written Rust compatibility conversions in +`crates/sidecar-protocol/src/protocol.rs`. Replace its empty compatibility +`GetProcessSnapshotRequest {}` with the generated wire type alias, copy both +request fields in both conversion directions, and copy both unavailable lists +in `ProcessSnapshotResponse`. Generated Rust remains Cargo build output. + +## One shared sidecar-owned history + +### Add `crates/native-sidecar-core/src/process_history.rs` + +Create a small `ProcessTerminalHistory` around a +`VecDeque`. It should be constructed with the resolved +sidecar retention, expose read-only iteration, answer process-ID conflicts, and +push one terminal entry while evicting oldest-first until `len <= capacity`. + +Also put the expectation validator/classifier here so native and browser cannot +diverge on duplicate handling, bounds, or unavailable ordering. Its output +should preserve caller expectation order for deterministic wire results. + +Re-export the history and classifier from +`crates/native-sidecar-core/src/lib.rs`. Keep the capacity passed in from +`process_route_retention(&limits)`; do not copy the default constant into either +adapter and do not make the clients supply a history size. + +Focused shared-core tests must prove: + +- capacity is exact and oldest-first for capacities 1 and 2; +- active and retained entries both satisfy expectations; +- missing expected PIDs and process IDs are classified explicitly and in input + order; +- duplicate/invalid/over-limit expectations are typed failures; and +- the near-limit threshold is shared and reports the observed/capacity values; +- a process ID conflicts while retained but becomes reusable after authoritative + eviction, preserving native's existing behavior. + +### Native adapter edits + +In `crates/native-sidecar/src/state.rs`, replace +`exited_process_snapshots: VecDeque` and the wrapper +struct with `ProcessTerminalHistory`. Initialize it in +`crates/native-sidecar/src/vm.rs` with the resolved retention. + +In `crates/native-sidecar/src/execution.rs`: + +- push the existing complete terminal `ProcessSnapshotEntry` through the shared + history in `finish_active_process_exit`; +- replace direct FIFO iteration/contains/pruning in `snapshot_vm_processes`, + `vm_has_process_id`, `kill_process_internal_with_source`, and + `get_process_snapshot` with the shared history methods; +- delete `prune_exited_process_snapshots`; capacity enforcement occurs at the + sidecar-owned insertion point, not during reads; and +- pass the full snapshot plus request expectations to the shared classifier and + return both unavailable lists through `process_snapshot_response`. + +Keeping pruning at insertion makes the retention invariant continuous and +removes policy work from a read request. Preserve native behavior that killing a +retained terminal process is an idempotent success and that an explicit process +ID cannot be reused until its retained record expires. + +### Browser adapter edits + +In `crates/native-sidecar-browser/src/wire_dispatch.rs`: + +1. Add a VM-keyed `ProcessTerminalHistory` map. Create each history from that + VM's resolved limits during VM initialization and remove it in + `purge_vm_state`. +2. Extend `ExecutionRecord` with the complete initial protocol + `ProcessSnapshotEntry`. After `start_execution_with_options`, obtain the new + execution's entry through the existing + `BrowserSidecar::process_snapshot_entries`, replace its bridge execution ID + with the public wire `process_id`, and store it with the record. Return that + entry's real PID in `process_started_response` instead of the current `None`. + Treat a missing just-started entry as `execute_failed`; fail closed by + releasing the just-started execution and context, preserving cleanup errors, + rather than orphaning a worker. Do not manufacture PID/process metadata in + the client. +3. On `ExecutionEvent::Exited`, change the stored entry to `Exited`, set the + exact exit code and sidecar clock exit time, and push it into the VM's shared + history before removing active wire routes. Do this for ordinary, cron, and + internal executions alike so browser/native churn accounting is identical. +4. Append retained history to active entries in `get_process_snapshot`, then use + the shared expectation classifier and return explicit unavailable lists. +5. Include retained IDs in execute-conflict detection and make kill of a + retained terminal ID an idempotent success, matching native. + +Do not retain workers, contexts, captured-output buffers, ownership envelopes, +or bridge execution handles in terminal history. Store only the compact process +snapshot fields. Browser worker/kernel cleanup must remain immediate. + +`crates/native-sidecar-browser/src/service.rs` needs no second history. Its +active execution table should remain active-only; protocol terminal correlation +belongs to the wire sidecar state that owns public process IDs. + +### Shared response builder + +Change `process_snapshot_response` in +`crates/native-sidecar-core/src/frames.rs` to accept `processes`, +`unavailable_pids`, and `unavailable_process_ids`. Update its native and browser +callers. Do not encode unavailable correlation as `RejectedResponse`; one bulk +snapshot can legitimately contain available and expired expected records at the +same time. + +## Thin-client edits + +### Runtime-core transport + +Change `SidecarProcess.getProcessSnapshot` in +`packages/runtime-core/src/sidecar-process.ts:1653-1674` to accept an optional +expectation object and return: + +```ts +interface SidecarProcessSnapshot { + processes: SidecarProcessSnapshotEntry[]; + unavailablePids: number[]; + unavailableProcessIds: string[]; +} +``` + +Forward only fields the caller supplied. Validate that unavailable values are a +subset of the corresponding expectations, that no expected key is both returned +and unavailable, and that every expected key is classified exactly once as +returned or unavailable. Reject duplicate returned keys and duplicate +unavailable keys as malformed protocol. Do not decide retention or synthesize +unavailable keys in runtime-core. + +Update request/response mapping tests in +`packages/runtime-core/tests/request-payloads.test.ts` and +`response-payloads.test.ts`, including omitted, present-empty, mixed available, +and unavailable cases. Add focused `SidecarProcess.getProcessSnapshot` cases in +`packages/runtime-core/tests/sidecar-process.test.ts` for exact-once validation; +mapping tests alone do not exercise the request-correlated invariant. + +### TypeScript core + +Stack Item 71 after Item 70. Item 70 changes `Kernel.snapshotProcesses` to the +only asynchronous inspection surface; Item 71 should evolve it to accept +optional expectations and return the process array plus explicit unavailable +lists. `AgentOs.allProcesses()` calls it with no expectations and returns only +the response's `processes`. + +In `packages/core/src/sidecar/rpc-client.ts`: + +- forward expectation fields to `SidecarProcess.getProcessSnapshot`; +- map returned entries without caching them; +- make `processSnapshotById(processId)` send + `expectedProcessIds: [processId]` and return `undefined` only when the sidecar + explicitly includes that ID in `unavailableProcessIds`; +- throw a protocol invariant error if the expected ID appears in neither place; + and +- keep `processSnapshotRefresh` single-flight only for unqualified diagnostic + snapshots. Expectation-aware requests with different keys must not share an + in-flight response. Do not introduce a persistent keyed request cache. + +In `packages/core/src/agent-os.ts`: + +- `listProcesses` sends every locally tracked PID as `expectedPids`, removes + routes explicitly listed in `unavailablePids`, and returns the remaining + public processes; +- `getProcess(pid)` sends that expected PID, removes an explicitly unavailable + route, and throws the existing `Process not found: ` result; +- if a requested PID is neither present nor explicitly unavailable, throw a + malformed-sidecar invariant error rather than guessing expiry; and +- `waitShell` / `closeShell` retain their existing not-found behavior, but their + `processSnapshotById` result is now based on the explicit sidecar unavailable + list rather than raw absence. + +The client should not compare its route count with +`processRouteRetention`, count unrelated operations, attach a TTL, or preserve a +terminal fallback after the sidecar reports unavailable. + +### Rust client + +In `crates/client/src/process.rs`, make the private snapshot helper accept +expected PIDs/process IDs and return a small internal result containing entries +and both unavailable lists. + +Validate the same exact-once response invariant at the Rust wire boundary before +reconciling any route. The sidecar returning neither classification, both +classifications, a duplicate, or an unrequested unavailable key is a protocol +error and must not mutate client state. + +- `list_processes` sends all local SDK PIDs, removes routes explicitly marked + unavailable, and maps only the still-authoritative entries; +- `get_process` sends one expected PID, removes it on explicit unavailability, + and returns the existing `ClientError::ProcessNotFound(pid)`; +- missing-but-not-unavailable is a `ClientError::Sidecar` protocol invariant, + not expiry; and +- `all_processes` sends no expectations and returns the snapshot entries. + +In `crates/client/src/shell.rs`, have +`process_snapshot_entry_by_id` send `expected_process_ids` and return `None` only +for explicit unavailability. `wait_shell` and `close_shell` can keep their +existing `ShellNotFound` public result. + +Do not add client terminal sequence numbers or a second Rust/TypeScript history +map. Item 72 may compact Rust's retained host callback routes after this item, +but that state remains separate from authoritative process inspection. + +## Before and after tests + +### Before evidence + +Record these two failures before production edits: + +1. In `crates/native-sidecar-browser/tests/wire_dispatch.rs`, execute one + process, emit and poll its `ExecutionEvent::Exited`, then request a process + snapshot. Current browser behavior returns no entry for the just-exited + process despite advertising terminal retention. +2. In the native sidecar service test seam, retain one public-spawn-labelled + terminal entry, add `DEFAULT_PROCESS_ROUTE_RETENTION` later entries labelled + as finite exec/shell/ACP churn, then query. Current native behavior evicts the + first record, while the response has no field that tells a still-retaining + client that the missing PID is authoritative expiry. + +For TypeScript and Rust, add focused client tests first with a snapshot response +that omits a locally retained completed PID. Record the current +`sidecar process snapshot is missing tracked process` errors. Those tests become +the after tests by adding explicit unavailable fields and asserting route +reconciliation. + +### Shared history and adapter conformance + +Add `crates/native-sidecar-core` unit tests described above. Then add the same +adapter-level scenario to: + +- the native service process-snapshot tests in + `crates/native-sidecar/tests/service.rs`; and +- `crates/native-sidecar-browser/tests/wire_dispatch.rs` next to the existing + process snapshot test around lines 1309-1331. + +For each adapter: + +1. an active expected PID/ID is returned and unavailable lists are empty; the + browser `ProcessStartedResponse` contains that exact nonzero PID; +2. after exit, the same complete entry is returned as `Exited` with exact exit + code/timestamps; +3. a never-retained expected PID and ID appear in the corresponding unavailable + lists; +4. mixed available/unavailable expectations preserve request order; +5. after FIFO pressure, the oldest terminal keys become unavailable while the + newest capacity remains returned; and +6. explicit ID conflict/idempotent terminal kill behavior matches. + +Use fabricated/shared-history entries for the 1,025-entry pressure assertion; +do not launch 1,025 real V8/WASM guests. One real adapter execution per backend +is enough to prove lifecycle integration. + +### TypeScript client tests + +Extend Item 70's +`packages/core/tests/process-snapshot-forwarding.test.ts` to prove exact +expectation forwarding, unavailable conversion, unqualified single-flight, and +non-coalescing expectation-aware requests. + +Extend `packages/core/tests/leak-agent-os-processes.test.ts` with a mocked +authoritative snapshot: + +- completed local PID + `unavailablePids: [pid]` removes the route and is + omitted by `listProcesses`; +- `getProcess(pid)` then returns `Process not found`; +- missing PID with an empty unavailable list remains a hard protocol invariant; + and +- a returned completed entry preserves command/args/exit metadata. + +Add a `processSnapshotById` test proving a retained shell entry resolves, an +explicit unavailable ID maps to not-found, and missing-without-classification +rejects. + +### Rust client tests + +Add pure reconciliation tests beside `process.rs`'s existing terminal-retention +units. Cover a mixed available/unavailable batch, route removal, exact +`ProcessNotFound`, and missing-without-classification. Extend the shell lookup +test seam for retained, unavailable, and malformed responses. + +Keep the real native E2Es in `crates/client/tests/process_e2e.rs` and +`shell_e2e.rs`; add one late wait after unrelated lightweight churn if it can +reuse sidecar test commands without launching hundreds of real runtimes. The +shared-core capacity test is the authoritative pressure test. + +No client test should implement a retention counter. No sidecar history test +should move into a client suite. + +## Dependencies, risks, and non-goals + +- **Item 70 should land first.** It removes the stale TypeScript snapshot cache + and legacy `Kernel.processes` fallback.

Item 71 owns only snapshot + availability/history. +- **PID/process-ID reuse:** retained IDs remain conflicts; after authoritative + eviction native already permits reuse. Clients generate monotonic sidecar IDs + and do not submit explicit IDs, so normal SDK correlation remains unambiguous. +- **Do not retain output:** terminal history contains metadata and exit status, + not stdout/stderr. Finite capture already travels on `process_exited`. +- **Do not make bulk snapshot infinite:** it remains bounded by active kernel + limits plus terminal history. Availability fields do not extend history. +- **Do not return a global `historyTruncated` boolean:** once true, it cannot + identify which expected route expired and still forces client inference. The + explicit unavailable key lists are precise for the client-owned correlations. +- **Do not partition history by client API:** the sidecar intentionally sees one + Linux-like process namespace. Separate spawn/exec/shell quotas would encode + SDK concepts in runtime policy and would still leave browser divergence. + +## Item 74 adjacent defect — do not fold it into Item 71 + +Item 69's research identified that after a genuine +`NativeSidecarKernelProxy.runEventPump` failure, `pumpError` is set but +`startTrackedProcess` never checks it. A later spawn can therefore start a guest +process when that proxy has no live event consumer, leaving its host wait route +unable to complete. + +Tracker Item 74 now owns that defect: + +- Item 22 covers bounded/loss-aware existing event subscriptions and fail-closed + cleanup of a route that loses its stream; +- Item 59 covers post-start stdin/EOF failure cleanup; +- Item 69 covers callback exceptions entering and stopping a healthy pump; +- Item 71 covers terminal snapshot/history availability after process lifecycle + events; and +- Item 74 rejects starts after a known pump failure and closes the concurrent + start/failure race. + +Do not make Item 71's snapshot lookup or terminal history compensate for a +process started without a live event route.

Compaction should make the implementation match those comments and the +TypeScript behavior. + +### Shutdown is the only current full cleanup + +`close_process_routes` at `agent_os.rs:590-604` sends terminal failures through +every entry's channels and then calls `drain_process_output_tasks`. + +`drain_process_output_tasks` at `process.rs:1228-1241` removes all entries, +takes all callback handles, and aborts them. This remains appropriate for +still-running routes during authoritative VM shutdown, but it should not be the +normal lifetime of callbacks belonging to a process that already exited. + +### TypeScript already has the desired shape + +`packages/core/src/agent-os.ts:1273-1294` has separate +`RunningProcessRoute`, `CompletedProcessRoute`, and `FailedProcessRoute` types. +`_trackProcess` at current lines 1669-1704 clears handler sets and replaces the +running entry with `{ state: "exited", exitCode }` or +`{ state: "failed", error }` before pruning. + +Its public terminal behavior at `agent-os.ts:1742-1813,2111-2131` is: + +- stdin writes, stdin close, stop, and kill are no-ops after successful exit; +- late stdout/stderr subscriptions contain no live handler route; +- a late exit callback fires immediately; +- a late wait resolves immediately; and +- a stored route failure is rethrown. + +Rust should achieve the same semantics with Rust's stream/watch API, not by +retaining live channels. + +## Exact production edits + +### `crates/client/src/agent_os.rs` + +Replace the single full `ProcessEntry` struct with an enum and a running-only +payload. Suggested shape: + +```rust +pub(crate) enum ProcessEntry { + Running(RunningProcessRoute), + Terminal { + exit: ProcessExit, + terminal_sequence: u64, + }, +} + +pub(crate) struct RunningProcessRoute { + pub stdout_tx: broadcast::Sender>>, + pub stderr_tx: broadcast::Sender>>, + pub exit_tx: watch::Sender>, + pub process_id: String, + pub output_tasks: Vec>, +} +``` + +The terminal variant must not contain sender values, a process ID, task handles, +or an atomic live/terminal sentinel. Keep `next_process_terminal_sequence` on +`AgentOsInner`; the registry lock still serializes assignment and pruning, so a +plain `u64` is sufficient inside a terminal entry. `AtomicU64` remains needed +for the global sequence allocator. + +Update `close_process_routes` to send `EventStreamClosed` only through +`ProcessEntry::Running` entries. Terminal entries already carry their final +result and have no live channels. Then drain the complete map as today. + +### `crates/client/src/process.rs`: registration and transition + +Wrap the entry created by `spawn` in `ProcessEntry::Running`. Keep all live +fields and callback installation behavior unchanged. + +Replace `record_process_terminal_and_prune` with a helper such as +`compact_process_terminal_and_prune` that receives the PID, exact +`ProcessExit`, completion sequence, and advertised retention count. The caller +continues to hold `process_registry_lock`; use `SccHashMap::update` to replace a +running entry: + +```rust +*entry = ProcessEntry::Terminal { + exit, + terminal_sequence, +}; +``` + +Do not abort `output_tasks` during normal compaction. Assignment drops each +`JoinHandle`, which detaches rather than aborting its task, and drops the +registry's sender clones. Once `run_spawn_events` returns and drops its own +sender clones, callback receivers can drain already-queued output in protocol +order, observe channel closure, and end naturally. Aborting at the transition +can discard output that was sent before `ProcessExitedEvent` but has not yet +been scheduled in the callback task. + +Change `run_spawn_events` so its event loop returns the exact `ProcessExit` it +sent to `exit_tx`, then pass that value into the compaction helper. The smallest +mechanical form is: + +```rust +let terminal_exit = loop { + let event = match events.recv().await { + Ok(event) => event, + Err(WireEventRecvError::Lagged { skipped }) => { + let exit = ProcessExit::EventStreamLagged { skipped }; + let _ = stdout_tx.send(RoutedStreamEvent::Lagged { skipped }); + let _ = stderr_tx.send(RoutedStreamEvent::Lagged { skipped }); + let _ = exit_tx.send(Some(exit.clone())); + self.abort_wire_process_after_route_failure(&process_id, "spawn") + .await; + break exit; + } + Err(WireEventRecvError::Closed) => { + let exit = ProcessExit::EventStreamClosed; + let _ = stdout_tx.send(RoutedStreamEvent::Closed { + context: "process output route closed before process exit", + }); + let _ = stderr_tx.send(RoutedStreamEvent::Closed { + context: "process output route closed before process exit", + }); + let _ = exit_tx.send(Some(exit.clone())); + break exit; + } + }; + if event.ownership != ownership { + continue; + } + match &event.payload { + EventPayload::ProcessExitedEvent(event) if event.process_id == process_id => { + let exit = ProcessExit::Exited(event.exit_code); + let _ = exit_tx.send(Some(exit.clone())); + break exit; + } + // existing ordered stdout/stderr forwarding and unrelated-event cases + } +}; + +let _registry_guard = self.inner().process_registry_lock.lock(); +let terminal_sequence = self + .inner() + .next_process_terminal_sequence + .fetch_add(1, std::sync::atomic::Ordering::AcqRel); +compact_process_terminal_and_prune( + &self.inner().processes, + pid, + terminal_exit, + terminal_sequence, + self.inner().process_route_retention, +); +``` + +Retain the current complete stdout/stderr and unrelated-event arms in the +elided match. Preserve the current ordering: + +1. send output route failure where applicable; +2. send the terminal value to the exit watch so existing waiters wake promptly; +3. perform the existing route-failure wire abort where applicable; and +4. atomically compact and prune. + +Do not infer the terminal value later from the watch sender. Carrying one typed +value through the pump avoids a second state machine and guarantees the compact +entry matches the result observed by in-flight receivers. + +Update `prune_terminal_processes` to collect sequences only from +`ProcessEntry::Terminal`. Update `terminal_pids_to_prune` to accept only actual +terminal `(pid, sequence)` pairs; zero no longer means live. Preserve +completion-order pruning and the exact sidecar-advertised count, including zero. + +Update `drain_process_output_tasks` to remove every registry entry but extract +and abort handles only from `ProcessEntry::Running`. A terminal variant should +be removed silently because it cannot contain tasks. Keeping the existing +helper name is fine; its shutdown-only role remains accurate. + +### `crates/client/src/process.rs`: late routes and controls + +Match on `ProcessEntry` in every registry reader: + +- `on_process_stdout` and `on_process_stderr`: subscribe only when running; for + a terminal success return an already-ended `ByteStream`, and for terminal lag + or closure return the existing typed failed stream; +- `on_process_exit`: subscribe to the running watch, or process the terminal + value immediately with the same synchronous success/logged-failure behavior; +- `wait_process`: subscribe when running, or call `process_exit_result` directly + when terminal; +- `lookup_process_id`: replace it with a helper returning + `Result, ClientError>`; return `Some(id)` when running, + `None` for `Exited`, and the typed `process_exit_result` failure for a terminal + route failure; and +- `write_process_stdin`, `close_process_stdin`, and `signal_process`: return + `Ok(())` without a wire request for `None`. + +Do not hold an `scc` read guard while invoking a caller callback. Copy the +terminal value or create the running receiver inside `read`, release the guard, +and only then call the handler or await. + +`list_processes` and `get_process` need only key membership and therefore do not +need semantic changes. Do not make snapshot absence mean terminal expiry; Item +71 owns that separate protocol contract. + +### `crates/client/src/stream.rs` + +Add a crate-private constructor for an already-ended byte stream, for example: + +```rust +pub(crate) fn empty() -> Self { + let (tx, rx) = broadcast::channel(1); + drop(tx); + Self::new(rx) +} +``` + +This allocates only an ephemeral channel for that returned stream. It does not +retain senders or a route in the registry. Keep `ByteStream::failed` unchanged +for a one-shot typed lag/closed error. + +Refactor `byte_stream_for_process_route` into explicit running and terminal +paths (or an equivalent small enum-returning helper). Avoid creating a dummy +receiver before the registry lookup for terminal routes. + +### No sidecar, protocol, or TypeScript production change + +The sidecar already owns the retention policy in +`crates/native-sidecar-core/src/limits.rs:17-28` and advertises the resolved +value in VM initialization. Rust already consumes that field. Moving callback +senders or Rust `FnOnce` handlers into the sidecar is neither possible nor +desirable; they are host-language resources. + +Do not modify: + +- native or browser sidecar process retention; +- initialize response frames; +- TypeScript route types; +- process snapshot lookup/expiry semantics; or +- VM limit defaults. + +## Before and after tests + +### Before and after: one durable callback-lifetime regression + +Write the intended final regression first, run it against the vulnerable +parent, retain the failure output for the tracker, and keep the same test after +the production change. Suggested name: +`terminal_transition_releases_output_callbacks_after_draining_ordered_output`. +It should: + +1. create stdout/stderr and exit channels, install one callback, and retain its + `AbortHandle` for observation; +2. insert the current full entry for the red run, then + `ProcessEntry::Running` for the final version; +3. enqueue a final output chunk before the terminal result and retain an + in-flight exit watch receiver; +4. send the exit value, invoke the current mark helper for the red run (the + compact helper afterward), and drop the pump's external sender + clones; +5. assert the callback receives the queued final chunk; +6. assert its `AbortHandle` eventually becomes finished without calling + `abort`, proving sender removal closed the receiver naturally. +7. in the final version, also assert the map matches only + `ProcessEntry::Terminal { exit, terminal_sequence }`. + +For the red-before run, make the smallest test-only adaptation needed to build +against the old full `ProcessEntry` and invoke +`record_process_terminal_and_prune`. The callback-finished assertion must fail: +retaining the terminal entry retains the sender, so the callback task cannot +finish. +After introducing the enum and compaction helper, adapt only the construction +and helper call; the same intended assertion turns green. Do not record a +temporary test that merely confirms the bug and then delete it—the lasting +regression is what prevents sender/task retention from returning. + +Use the same focused command for both evidence runs: + +```bash +cargo test -p agentos-client \ + process::tests::terminal_transition_releases_output_callbacks_after_draining_ordered_output \ + -- --exact +``` + +Record the vulnerable parent revision plus the expected timeout/not-finished +assertion in the tracker before implementing, then record the green command on +the dedicated Item 72 revision. + +The enum shape makes sender/task absence a compile-time property. Do not add +dummy `Option` or empty task vectors to the terminal variant merely to +make a runtime field assertion possible. + +The existing tests at `process.rs:1390-1499` are supporting evidence: they prove +the registry owns callback handles and shutdown aborts them, but they do not +currently exercise ordinary process completion. + +### After: compaction, pruning, and in-flight receivers + +Adapt `terminal_pruning_preserves_an_in_flight_wait_receiver` at current +`process.rs:1527-1577` to the enum. It must still prove that: + +- the oldest compact terminal route is removed by completion order; +- the newest compact terminal route remains; +- live routes are never included in terminal pruning; and +- a watch receiver acquired while running observes the exact terminal result + even after the map entry is replaced and later pruned. + +Add a zero-retention case. The compact route may be removed immediately, but a +receiver obtained before terminal delivery must still resolve because the watch +value is sent before replacement/removal. + +### After: late success/failure parity + +Extend `crates/client/tests/process_e2e.rs` immediately after the existing +successful `cat` wait at current lines 230-238. While the route is within the +advertised retention window, assert: + +- a second `wait_process(pid)` immediately returns the same exit code; +- a late `on_process_exit` invokes its callback synchronously exactly once; +- late stdout and stderr streams terminate without yielding data; +- `write_process_stdin`, `close_process_stdin`, `stop_process`, and + `kill_process` all return `Ok(())`; and +- the no-op controls issue no semantic error after success. + +There is an intentional scheduling edge to account for: `run_spawn_events` +sends the exit watch value before it acquires `process_registry_lock` and +replaces the registry entry. Therefore the first `wait_process` can wake just +before compaction. Immediately construct the late stdout/stderr streams and +await their termination under a short timeout before asserting the second wait, +late exit callback, and no-op controls. Stream closure both synchronizes with +sender removal and makes an accidentally retained/open sender fail +deterministically instead of hanging the suite. + +Add a focused unit test for the new control target resolver as well. It should +prove `Running` returns `Some(process_id)`, terminal success returns `None` +(therefore no request can be assembled), terminal lag/closure returns the exact +typed error, and an absent PID remains `ProcessNotFound`. The E2E establishes +the public `Ok(())` behavior; this unit test establishes that successful late +controls really skip the wire rather than relying on a permissive sidecar. + +Retain and adapt these current typed failure tests in `process.rs`: + +- `late_process_output_subscriber_receives_retained_route_failure` at current + lines 1377-1388; +- `closed_process_event_stream_is_an_error_not_exit_zero` at lines 1506-1511; + and +- the lagged `process_exit_result` coverage near lines 1306-1318. + +Add a direct compact-terminal failure case for both `EventStreamLagged` and +`EventStreamClosed`: late wait/control resolution must return the same typed +`ClientError`, and late stdout/stderr must emit one typed error then terminate. +Do not convert failures into exit code zero, empty success, or +`ProcessNotFound`. + +Add one `stream.rs` unit test that `ByteStream::empty().next().await` returns +`None` immediately. Keep the existing failed-stream test green so the empty +success constructor cannot accidentally erase a typed route failure. + +### Shutdown coverage + +Update `confirmed_shutdown_terminally_clears_all_host_route_collections` in +`crates/client/src/agent_os.rs:2081-2173` to insert a running enum variant. Keep +its assertions that authoritative shutdown sends route closure, empties the +registry, and aborts callback tasks for processes that are still live. + +Add a compact terminal entry to the same test or a smaller adjacent test and +assert shutdown simply removes it. It has no sender/task to notify or abort. + +## Research baseline + +On research revision `22adc1cd6736`, the existing focused suites are green: + +```text +cargo test -p agentos-client process::tests + 13 passed; 0 failed +cargo test -p agentos-client stream::tests + 2 passed; 0 failed +cargo test -p agentos-client agent_os::tests::confirmed_shutdown_terminally_clears_all_host_route_collections + 1 passed; 0 failed +``` + +That is 16 focused tests passing before the new regression is introduced. It +does not prove ordinary terminal callback cleanup; the durable red-before test +above supplies that missing evidence. + +## Validation commands + +Run focused unit coverage first: + +```bash +cargo test -p agentos-client process::tests +cargo test -p agentos-client stream::tests +cargo test -p agentos-client agent_os::tests::confirmed_shutdown_terminally_clears_all_host_route_collections +cargo check -p agentos-client +cargo fmt --all -- --check +``` + +Then run the real process integration and workspace gate: + +```bash +cargo test -p agentos-client --test process_e2e -- --nocapture +cargo check --workspace +git diff --check +``` + +The E2E test starts a native VM and belongs after the focused tests. + +## Dependencies, overlaps, and risks + +- **Item 71 owns terminal snapshot expiry.** Item 72 must not infer expiry from + snapshot absence or add a new protocol lookup. Compact host-route retention + remains keyed by the sidecar-advertised count until Item 71 defines the + cross-adapter contract. +- **Item 57 may change exit subscription failures.** Preserve the current typed + `ProcessExit` in the compact variant so a later result-bearing + `on_process_exit` API can expose it. Do not deepen the current log-only branch + as part of Item 72. +- **Item 59 may change finite-exec stdin ownership.** Do not fold its atomic + finite-input/fail-closed cleanup work into this revision. If it lands first, + preserve its control failure behavior while changing only public-spawn route + storage and late terminal lookup. +- **Do not abort normal callback tasks at completion.** Protocol ordering means + output precedes exit on the pump, but the independent callback task may not + have run yet. Dropping the handle detaches it; dropping the final senders lets + it drain and finish safely. +- **Preserve transition races.** A reader must observe either `Running` or + `Terminal`, never a partly-cleared running value. If it obtains a running + watch/output receiver immediately before replacement, the terminal event and + sender closure still carry it to completion. +- **Preserve typed route failures.** A compact failure is not equivalent to a + successful exit or an unknown PID. Store the exact `ProcessExit` clone used by + the live watch. +- **Retention zero is valid.** Replacement followed by immediate pruning must + not strand already-subscribed waiters. +- **Do not remove the global sequence allocator.** Only the per-entry atomic + sentinel disappears.

Keep the wasm sidecar and the authoritative projected VFS on the main +thread. The runtime host should bind the driver's already-running primary Worker +when Rust registers an ordinary `exec`/`run` execution, but start one additional +ordinary production Worker for each sidecar-requested ACP adapter execution. +That distinction prevents the existing primary execution from being launched +twice. Each ACP Worker executes the exact entrypoint path supplied by the Rust +sidecar and asynchronously forwards only stdin/stdout/stderr/exit and guest +syscall traffic. + +Preserve two distinct frame paths: + +```text +guest syscall in a Worker + -> synchronous raw wasm pushFrame + -> sidecar/kernel response + +public ACP list/create/prompt + -> asynchronous pushFrameAsync + -> raw wasm pushFrame returns AcpPending internally + -> await exact adapter Worker's output + -> raw deliver/abort frames back to the sidecar + -> final ACP response only +``` + +Do **not** make the raw guest-syscall dispatcher asynchronous. A Worker blocked +in the existing SharedArrayBuffer sync bridge requires that path to remain +synchronous. Add a second, explicitly asynchronous frame method for extension +requests instead of using a `Uint8Array | Promise` union. + +Delete `AgentOsConvergedSidecarOptions.agentExecutor`, `SyncAgent`, +`SyncAgentExecutor`, the in-process line handler/session maps, and the +path-to-prebuilt-worker lookup in the browser-WASM fixture. The only caller-side +data remains opaque package bytes and explicit runtime configuration. Package +metadata, agent resolution, entrypoint selection, ACP state, deadlines, restart +decisions, and cleanup stay in Rust. + +Priority: **P1**. Boundary confidence: **high**. Implementation confidence: +**medium-high**. The standard Worker, synchronous kernel bridge, projected VFS, +resumable Rust ACP core, and package projection all exist. The nontrivial part is +extracting the existing Worker controller so multiple isolated adapter Workers +can share one sidecar VM without sharing mutable Worker globals. + +## Original issue + +The tracker entries are at `docs/thin-client-migration.md:119,201,288`. + +The public factory currently advertises browser ACP support but defaults to a +bridge that never executes an adapter: + +- `createAgentOsConvergedSidecar` constructs + `createConvergedExecutionHostBridge({ agentExecutor: undefined })`; +- `startExecution` merely echoes `nextExecutionId`; +- `createWorker` merely returns a generated string; +- stdin, kill, event polling, and worker termination have no real execution to + control; and +- a pending ACP create/prompt therefore cannot produce adapter output. + +The optional workaround is not production behavior. It accepts a +`SyncAgentExecutor`, parses newline-delimited ACP JSON in TypeScript, retains +sessions and output queues, and creates fake output in the browser client. That +is exactly the parallel client implementation Item 73 must remove. + +The browser-WASM async tests prove that a Worker/reactor arrangement can run, but +they do not prove the public factory. `async-kernel.worker.ts` maps an argv path +through `AGENT_WORKERS` and falls back to `DEFAULT_AGENT_WORKER_URL`; the packed +fixture entrypoint itself is only this comment: + +```js +// Browser worker execution is supplied by the test host bridge. +``` + +Changing or deleting the projected file therefore does not change which test +program executes.

It must distinguish binding the reserved primary Worker from spawning an ACP service Worker; no agent implementation or output policy belongs here. | +| Pending router | `packages/browser/src/acp-pending-driver.ts:7-221` | `pollAgentOutput` and the returned frame function are synchronous; binds a pending process to the most recently spawned fake execution. | Make the router asynchronous and consume a sidecar-returned exact `{ processId, executionId }` route. Fold/delete the extra synchronous drive-loop layer if that keeps the diff smaller. | +| Runtime factory contract | `packages/runtime-browser/src/runtime-driver.ts:68-95` | `loadSidecar()` receives no execution host; handle exposes only synchronous `pushFrame`. | Pass a runtime-owned execution host to `loadSidecar(host)`.

Split raw synchronous and pending-aware asynchronous frame dispatch + +In `packages/runtime-browser/src/runtime-driver.ts`, change the contracts to the +following shape (names may vary, but keep the separation explicit): + +```ts +export interface ConvergedSidecarHandle { + /** Raw, non-awaiting wasm dispatch used by guest sync syscalls. */ + pushFrame(frame: Uint8Array): Uint8Array; + /** Pending-aware dispatch used by public extension requests. */ + pushFrameAsync?(frame: Uint8Array): Promise; + setNextExecutionId?(executionId: string): void; +} + +export interface ConvergedSidecarFactoryOptions { + loadSidecar( + executionHost: ConvergedExecutionHost, + ): Promise; + // existing config/packages/codec fields remain unchanged +} +``` + +Define `ConvergedExecutionHost` in runtime-browser, not in the AgentOS package. +It is the generic browser capability that owns standard Workers. It should +accept the already-decoded `createWorker` request, route byte-preserving stdin, +kill/terminate exact executions, and asynchronously wait for exact execution +output. Suggested minimum surface: + +```ts +export interface ConvergedExecutionHost { + bindExistingExecution(executionId: string): void; + reserveExecution(request: { + vmId: string; + argv: readonly string[]; + env: Readonly>; + cwd: string; + }): { executionId: string }; + createWorker(request: ConvergedWorkerSpawnRequest): { + workerId: string; + runtime: "java_script" | "web_assembly"; + }; + writeStdin(executionId: string, chunk: Uint8Array): void; + closeStdin(executionId: string): void; + kill(executionId: string, signal: number): void; + terminate(executionId: string, workerId: string): void; + waitForOutput( + executionId: string, + deadlineMs: number, + isCancelled?: () => boolean, + ): Promise<{ kind: "stdout" | "stderr" | "exit"; payload: Uint8Array } | null>; +} +``` + +The exact public names can differ, but the host needs two unambiguous routes: + +1. **Pre-bound primary execution.** Before `ConvergedExecutorSession` registers + the driver's ordinary guest execution, bind its exact execution ID to the + existing primary `BrowserWorkerSession`. The following Rust + `startExecution`/`createWorker` callbacks consume that reservation and attach + the Rust worker ID to the same Worker. They must not allocate a second Worker. +2. **Sidecar-requested service execution.** An ACP launch has no primary + reservation. Its `createWorker` callback creates an isolated standard Worker + controller from the exact Rust spawn request and stores the execution/worker + route for stdin, output, signals, and teardown. + +This correlation is legitimate host-only state; it does not choose an agent or +implement runtime policy. A duplicate reservation, mismatched execution ID, or +second worker binding must fail with a typed error instead of falling back to a +new Worker. + +`ConvergedWorkerSpawnRequest` must mirror the data Rust already serializes in +`native-sidecar-browser/src/wasm.rs:884-917`: VM, context, execution, runtime, +entrypoint, process identity/config, OS config, and WASM tier. Do not omit the +entrypoint and recover it from argv in TypeScript. + +Update `packages/runtime-browser/src/default-sidecar.ts`, runtime tests' fake +sidecars, and browser harness loaders for the new `loadSidecar(host)` argument. +The generic sidecar should delegate its execution callbacks to the supplied host +instead of creating another no-op bridge. + +### 2. Extract the existing standard Worker controller + +Move the per-Worker mechanics currently embedded in +`BrowserRuntimeDriver`—`Worker`, control token, pending request map, sync bridge, +stdio routing, stdin/signal controls, and cleanup—into a package-private class, +for example `packages/runtime-browser/src/browser-worker-session.ts`. + +`BrowserRuntimeDriver` should use one instance for ordinary `exec`/`run` and +pre-bind it as described above. The new converged execution host should create a +separate instance only for a `createWorker` callback that has no existing-worker +reservation (the ACP service case). This is necessary because `worker.ts` has +realm-global mutable state (`activeExecutionId`, module cache, process config, +stdin hooks, signals). Running two live ACP adapters in one Worker would corrupt +correlation, while blindly creating a Worker for the primary registration would +run ordinary guest code twice. + +Each adapter Worker must share the already bootstrapped `ConvergedServicer`, not +construct another sidecar or VM. Give each Worker session its own sync-bridge +buffers, but route its `BrowserWorkerSyncRequestMessage` to: + +```ts +convergedServicer.route(exactExecutionId, operation, args, hostCapabilityFallback) +``` + +Use the `executionId` from the Rust `BrowserWorkerSpawnRequest` as the only route +key. Validate `requestId + executionId + controlToken` exactly as the current +driver does. Do not create one `BrowserRuntimeDriver` per adapter: that would +bootstrap a different VM and the adapter would not see the ACP owner's projected +filesystem. + +### 3. Add a standard Worker "execute projected entrypoint" mode + +In `packages/runtime-browser/src/worker-protocol.ts`, add a distinct request, +for example: + +```ts +| { + controlToken: string; + id: number; + type: "execute-entrypoint"; + payload: { + executionId: string; + entrypoint: string; + argv: string[]; + env: Record; + cwd: string; + }; +} +``` + +In `packages/runtime-browser/src/worker.ts`, execute that path through the +already-installed runtime `require`/module loader. The Worker must not receive +the entrypoint's source from the main thread. A fixed internal bootstrap such as +calling the runtime `require(entrypoint)` is fine; fetching, `readFile` on the +main thread, mapping a path to a bundle URL, or embedding a source fallback is +not. + +Resolve `/opt/agentos/bin/*` through the existing VFS/module seam and accept the +normal executable JavaScript shebang in the loaded file (strip it in the +Worker-side module compiler only if the existing compiler does not already do +so). Initial Item 73 support may be JavaScript-only if that is the only native +ACP adapter runtime currently supported, but a Rust request for an unsupported +`web_assembly` entrypoint must fail with a typed unsupported-runtime error. It +must never substitute JavaScript source or a bundle URL. + +This mode is a sidecar-owned service execution, not generic +`ExecOptions.persistent`. It must: + +- set `process.argv`, cwd, env, pid/ppid/uid/gid from the Rust spawn request; +- keep streaming stdin open; +- report the real exit code; +- remain alive until the sidecar closes stdin, sends a signal, or terminates the + worker; and +- **not** use `PERSISTENT_EXEC_TIMEOUT_MS` at `worker.ts:90-93,3548-3556`. + +The ACP core already supplies phase deadlines and owns session lifetime. A +second 120-second Worker timeout would recreate client policy and kill healthy +long-lived sessions. + +### 4. Preserve output and bound the unavoidable host queue + +The current stdio path truncates each message through `boundStdioMessage` at +`worker.ts:1217-1222,1741-1748`. Truncating an ACP JSON-RPC line produces invalid +JSON. Change this path to chunk without data loss, or add a binary execution +output message used only by sidecar-managed service Workers. + +The runtime-owned execution host may retain output while the asynchronous +pending driver is between turns, so that queue must be bounded. Use both: + +- a per-message byte maximum enforced before `postMessage`; and +- a per-execution aggregate queued-byte maximum with a near-limit warning. + +On overflow, terminate that exact Worker, wake its waiter with a typed error that +names the observed bytes, configured capacity, and how to raise it, and let the +pending driver submit `driver_failed` to the sidecar. Do not silently truncate, +drop oldest output, spill to client filesystem, or reuse the unbounded +`AgentSession.events` array. + +Keep output identity channel-derived from the Worker route and verify every +message's control token/request/execution tuple before accounting it. A malicious +adapter must not be able to label output as another session. + +### 5. Make the pending driver asynchronous and use a Rust-owned exact route + +In `packages/browser/src/acp-pending-driver.ts`: + +- make `pollAgentOutput` return a promise; +- make `createAcpPendingResponseDriver` return + `(frame: Uint8Array) => Promise`; +- `await` stdout/stderr/exit without blocking the browser main thread; +- keep all ACP/frame inspection and construction behind wasm helpers; and +- preserve the current sidecar-owned timeout phase, abort, restart, stderr event, + and origin-response restoration behavior. + +Replace `pendingResponseProcessId` plus `bindPendingProcess` with: + +```ts +pendingResponseRoute(frame: Uint8Array): + | { processId: string; executionId: string } + | null; +``` + +Do not bind to `lastAgentExecutionId`. That is incorrect as soon as two owners or +sessions start adapters before the first pending interaction completes. + +In Rust: + +1. Construct one `BrowserAcpExtension`, retain its existing diagnostics handle in + `AgentOsBrowserSidecarWasm`, then register that same extension. +2. Add an owner-validating lookup on `BrowserAcpDiagnostics` for + `(connection_id, wire_session_id, vm_id, process_id) -> execution_id`. +3. Add `pending_frames::pending_route` that decodes the pending process and exact + VM ownership from the sidecar-written response. +4. Expose it as wasm `pendingResponseRoute`, returning only the two opaque IDs to + TypeScript. + +The lookup must reject a process route owned by a different connection/session/ +VM, even if the process string matches. Rust already stores the complete owner in +`BrowserAcpExecution`; no protocol field or TypeScript map is needed. + +After this change, delete from +`packages/browser/src/converged-execution-host-bridge.ts`: + +- `SyncAgent`, `SyncAgentExecutor`, and `agentExecutor` options; +- `AgentSession`, line buffering, base64-to-text fake dispatch, and fake event + arrays; +- `lastAgentExecutionId` and `pendingProcesses`; and +- the default no-op/synthetic `createWorker` path, replacing it with the exact + existing-primary bind or service-Worker spawn described above. + +What remains should only parse the JSON callback envelope emitted by wasm, +validate its fields, and delegate to the runtime-owned execution host. + +### 6. Route public extension calls on the main thread + +Add an asynchronous transport next to `PushFrameSidecarTransport` in +`packages/runtime-browser/src/converged-sync-bridge-handler.ts`. Share the same +frame encode/decode/rejected-response logic, but await `pushFrameAsync`. + +Expose a method on `ConvergedExecutorSession` and `ConvergedServicer` such as: + +```ts +dispatchExtensionRequest( + namespace: string, + payload: Uint8Array, +): Promise; +``` + +It must use the bootstrapped VM's exact ownership and return only the final +`ext_result`. Update `BrowserRuntimeDriver.dispatchExtensionRequest` at current +lines 1054-1064 to call that method instead of posting `type: "extension"` to the +guest Worker. Add the method to `NodeRuntimeDriver` so callers of +`createBrowserRuntimeDriverFactory` do not need an unsafe cast. + +Keep the Worker's current rejection for direct extension control messages. ACP +control belongs to the trusted main-thread transport, not the untrusted guest +realm. + +### 7. Complete sidecar-first teardown + +Add `dispose()` to `ConvergedExecutorSession`/`ConvergedServicer`: + +1. send `dispose_vm` with VM ownership; +2. send `close_session` with connection ownership; and +3. clear the local VM handle only after both terminal responses are validated. + +`BrowserRuntimeDriver.dispose/terminate` must invoke that sidecar teardown before +terminating the ordinary Worker-controller instances. The Rust disposal hook +already closes ACP owners and calls `terminateWorker`; the runtime host must make +that callback idempotently remove and terminate the exact Worker route. If +sidecar cleanup and Worker cleanup both fail, throw an `AggregateError` retaining +both errors. Do not silently clear maps first or swallow worker termination +failures. + +An ACP close-session request should release its adapter Worker immediately. Full +runtime disposal is the fail-safe for every remaining execution/context/VM route. + +## Test migration and focused regressions + +### Behavior-before tests + +These should be committed first in the dedicated Item 73 revision and shown +failing against its parent: + +1. In `packages/browser/tests/runtime-driver/converged-sidecar.test.ts`, replace + the fake-agent success tests with a runtime-host spy and prove that calling the + public factory without `agentExecutor` receives a Rust `createWorker` callback + but starts no real Worker and produces no adapter output. +2. Add a browser fixture whose projected bin returns a sentinel different from + every prebuilt worker. Run it through the old `async-kernel.worker.ts`; prove + the result still comes from `AGENT_WORKERS`/`DEFAULT_AGENT_WORKER_URL`, even if + the projected bin is changed to throw. This pins the substitution bug. +3. Retain the current unit assertions that `createWorker` only returns a generated + ID and lifecycle callbacks are no-ops as the small historical proof. Delete or + invert them only after the production host is installed. + +### Behavior-after unit tests + +Add focused runtime-browser tests for: + +- one ordinary primary execution registering with exactly one Worker, followed + by one ACP launch creating exactly one additional Worker; +- two simultaneous sidecar-managed Workers with distinct execution IDs, stdin, + output, process config, and module caches; +- `execute-entrypoint` loading a module available only through + `module.loadFile`, including the `/opt/agentos/bin/*` symlink; +- no main-thread read/fetch/source injection for that entrypoint; +- output chunks larger than 8,192 characters arriving intact; +- exact queue-cap overflow killing only the offending Worker with the typed + capacity error; +- sidecar close and driver dispose leaving zero Worker routes and rejecting any + outstanding wait exactly once; and +- a service Worker remaining alive beyond the generic persistent timeout until + the sidecar terminates it (mark a real-time saturation version skipped; use an + injected clock for the default suite). + +Convert `packages/browser/tests/runtime-driver/acp-pending-driver.test.ts` to +async and retain its current coverage for multi-phase deadlines, stderr, +restart, cancellation, driver failure, exact origin ownership, and no internal +pending response. Add interleaved two-owner/two-process output proving the Rust +route selects the right execution. Merge the useful +`agent-drive-loop.test.ts` cases into this suite if `agent-drive-loop.ts` is +deleted. + +Add Rust tests in `crates/agentos-sidecar-browser` proving: + +- pending route lookup returns the execution belonging to the response's exact + connection/session/VM; +- a same-named process under another owner is rejected; +- a released/aborted process has no route; and +- VM/session disposal leaves `sessions == 0`, `pending_interactions == 0`, and + `process_routes == 0` through `BrowserAcpDiagnostics::resource_counts`. + +Keep the existing `native-sidecar-browser` tests that assert the projected +entrypoint is passed unchanged and that exit/abort/dispose terminates the worker. +They already cover the Rust sidecar half of the boundary. + +### Public browser E2E + +Replace the path-mapped async harness with one Playwright gate built only from +public exports: + +1. load a real built `.aospkg` (prefer + `registry/agent/pi/dist/package.aospkg`); the existing Pi browser tests only + prove a static/prebundled adapter source path, so they are useful runtime + precedent but are not evidence that the projected package entrypoint runs; +2. pass its bytes to `createAgentOsConvergedSidecar` with no executor callback; +3. create the standard browser runtime factory/driver; +4. call the now-public extension dispatcher to list agents, create a session, + and prompt it against the existing deterministic model endpoint; +5. assert the selected adapter file exists only in the projected VFS—there is no + adapter bundle URL or host source fallback; +6. assert no `AcpPendingResponse` reaches the caller; and +7. close the ACP session and dispose the driver, then assert zero runtime Worker + routes and zero Rust ACP routes/pending interactions. + +If the full Pi prompt exposes a missing generic browser runtime primitive, fix +that primitive in this revision only when it is necessary to execute the +unchanged upstream adapter. Do not replace the adapter with a direct API stub or +fall back to the prebundled `pi-runner.ts` source-injection path. A small packed +echo fixture is useful for failure localization, but it does not replace the +required upstream-adapter gate. + +After the public gate passes, delete or reduce: + +- `AGENT_WORKERS` and `DEFAULT_AGENT_WORKER_URL` in + `async-kernel.worker.ts`; +- the empty-bin generation in `buildBrowserAgentPackageFixtures`; +- synchronous fake-agent tests and fixtures; and +- any browser test that decodes/builds ACP continuation frames in TypeScript + instead of using the wasm helpers. + +Retain `SabRing`, `KernelReactor`, and their generic unit tests if other browser +runtime features still use them. Item 73 removes the fake ACP production path, +not independently useful bounded transport primitives. + +## Risks and dependencies + +- **Shared-checkout prerequisite:** the current checkout contains in-progress + resumable pending-frame, timeout/abort, package-projection, and cleanup work. + Item 73 should be based on those revisions after they are shaped; do not copy + their changes into a second revision. +- **Multiple live adapters:** one Worker per execution is required. Reusing the + driver's single Worker is unsafe because its process/module/stdin state is + realm-global. +- **Primary-versus-service correlation:** ordinary execution registration must + bind the existing primary Worker, while an unbound ACP launch allocates a new + Worker. Treating every Rust `createWorker` callback as a new Worker request + duplicates ordinary guest execution; treating every callback as pre-bound + recreates the current ACP no-op. +- **Output integrity:** the present 8,192-character truncation is incompatible + with ACP. The replacement must preserve bytes while still bounding queued + transport state. +- **Lifecycle:** generic `persistent` carries a 120-second client timeout and is + unsuitable for ACP services. The sidecar must remain the only lifetime owner. +- **Upstream runtime parity:** Pi is the best existing E2E candidate, but its + current browser gate runs static/prebundled adapter source rather than the + projected package entrypoint. Its real `.aospkg` is large, so keep the new + projected-package proof in the explicit browser E2E rather than fast unit + tests. +- **No native/Rust-client behavior change:** this is the browser execution-host + seam. Do not add defaults or parallel ACP state to either SDK client. +- **No protocol schema change is required:** the exact execution mapping already + exists in `BrowserAcpExecution` and can be exposed through the wasm helper. + +## Exact changed-file inventory + +The smallest implementation is expected to touch these production surfaces: + +| File | Exact edit | +| --- | --- | +| `packages/browser/src/converged-sidecar.ts` | Remove `agentExecutor`; accept the runtime host in the loader; retain raw sync `pushFrame` and expose pending-aware `pushFrameAsync`. | +| `packages/browser/src/converged-execution-host-bridge.ts` | Delete the fake ACP implementation and maps; decode Rust callbacks and delegate exact execution/worker routes to the runtime host. | +| `packages/browser/src/acp-pending-driver.ts` | Make pending driving asynchronous and use the Rust-returned process/execution route. | +| `packages/runtime-browser/src/runtime-driver.ts` | Own the generic execution host; pre-bind the primary Worker; dispatch extensions on the main thread; terminate all Worker sessions. | +| `packages/runtime-browser/src/browser-worker-session.ts` (new) | Hold the extracted per-Worker control token, sync bridge, request/output routing, stdin/signal handling, bounds, and idempotent cleanup. | +| `packages/runtime-browser/src/worker-protocol.ts` | Add the internal projected-entrypoint execution request and lossless service-output messages.

Once terminal-event supervision is gone, +the client cannot safely wait for graceful termination or escalation. The Rust +client already names the same invariant with +`ROUTE_FAILURE_KILL_SIGNAL = "SIGKILL"` in +`crates/client/src/process.rs:29,767-777`. + +On successful cleanup, throw the **same `pumpError` object**, preserving its +typed fields and identity. If cleanup itself fails, report both failures in an +`AggregateError`, with the original pump error first and the exact normalized +cleanup error second. Do not swallow the cleanup rejection or pretend the +process was terminated. + +Do not call `failProcess(entry)` on this branch. `spawn` has not returned a +`ManagedProcess`, so nobody can observe `entry.waitPromise`; rejecting it would +create an unhandled rejection. Leaving the never-published entry unreachable is +safe, and its listener sets and closures are garbage-collectable because it was +never inserted into either tracking map. + +## Why this stays in the TypeScript client + +This is not VM behavior or process policy to move into the sidecar. It is a +TypeScript host-route lifecycle defect: the sidecar accepted `Execute`, but only +the client knows its local consumer promise has ended and can no longer route +the sidecar's already-emitted process events. + +The Rust client does not share this architecture. `AgentOs::send_execute` at +`crates/client/src/process.rs:697-734` calls +`request_wire_with_process_events`, which installs and returns the exact process +event subscription atomically with the `Execute` response. A missing binding is +already an error. Its per-process pump then handles typed lag/close failure. +Therefore Item 74 needs no Rust-client parity edit and no sidecar or wire-protocol +surface. + +Do not try to restart the TypeScript pump. Without a replay cursor and +acknowledgement contract, restart can silently skip or duplicate output and exit +events. Do not clear `pumpError`, retry `Execute`, synthesize an exit code, add a +timer, or teach the sidecar about a client's local promise state. + +## Before/after tests + +Extend `packages/core/tests/leak-rpc-client.test.ts`. Its existing stub already +exposes `failPump`, exposes tracking sizes through the proxy, and covers failure +of an existing process. Add deterministic deferred-`Execute`/`configureVm` +control and call spies to that stub as needed; do not add a production test +hook. + +| Regression | Before-fix proof | After-fix proof | +|---|---|---| +| Start after known pump failure | Fail the pump, wait until the catch has recorded/reported it, then call `spawn`.

Current code proceeds to `Execute`. | The post-reconfiguration guard rejects with the exact pump error; `execute` and `killProcess` are not called and both maps remain empty. | +| Pump fails while Execute is pending | Hold `execute` on a deferred promise, begin `spawn`, fail the pump, wait until failure is observed, then resolve `{ processId: "process-race", pid: 4242 }`. Current code resolves `spawn`, performs no kill, and leaves one route in each map. | Attach the rejection assertion before resolving the deferred promise. `spawn` rejects with the exact pump error, `killProcess(session, vm, "process-race", "SIGKILL")` is called once, and both maps remain empty. | +| Execute continuation wins | Resolve deferred `Execute` before rejecting the pump so registration's microtask runs first. | `spawn` may return its handle, but its `wait()` rejects with the exact pump error and both maps are released; the post-check does not double-kill.

The smallest current-tree barrier +is `vi.waitFor` on the exact private field in a test-only cast: + +```ts +await vi.waitFor(() => + expect( + (proxy as unknown as { pumpError: Error | null }).pumpError, + ).toBe(pumpError), +); +``` + +If Item 69 lands first, its one host-visible pump diagnostic may be used as the +barrier instead. A fixed number of arbitrary sleeps would make the race tests +flaky. Make `execute`, `killProcess`, and `configureVm` `vi.fn` stubs, and use a +small reusable deferred helper rather than production hooks. Keep the existing +test that a process already registered when the pump fails has its `wait()` +rejected and routes released. + +For tracker evidence, write the desired assertions first and run the focused +file against the vulnerable parent. The known-failure, post-mount, pump-first +Execute, and cleanup-failure cases must be red for the reasons in the table; +retain those same tests and make them green with the production edit. The +Execute-wins test is positive race coverage and should remain green on both +sides. + +## Research baseline + +On research revision `42c9f0e97cc1`, the existing focused suite is green: + +```text +pnpm --dir packages/core exec vitest run tests/leak-rpc-client.test.ts + 1 file passed; 5 tests passed; 0 failed +``` + +Those five tests cover existing-route failure and disposal cleanup, but none +starts a process after or concurrently with pump failure.

Expanding that client match to inspect +`invalid_state` message text would duplicate sidecar semantics in the SDK and +would misclassify unrelated invalid states. + +The source defect is `crates/agentos-sidecar-core/src/lib.rs:29-60`: +`AcpCoreError` has no session-not-found variant, so every shared-core missing or +cross-owner lookup is forced into `InvalidState`. + +## Exact current paths + +### Shared core taxonomy + +`crates/agentos-sidecar-core/src/lib.rs:29-87` defines `AcpCoreError`, maps its +variants to stable codes, formats messages, and serializes them through +`error_response` at lines 95-101.

Replace those exact constructions. Keep genuinely different +state-machine failures as `InvalidState`, including "session was removed during +adapter restart", missing pending interactions, busy sessions, malformed JSON, +and adapter restart failures. + +`close_session` and `begin_close_session` intentionally return idempotent +success for a missing or cross-owner session. Do not change that contract, and +do not mechanically replace unrelated `InvalidState` values merely because +they mention session cleanup or adapter failure. + +### Native and browser serialization + +Both adapters already turn shared-core errors into ACP response payloads: + +- native: `crates/agentos-sidecar/src/acp_extension.rs:497` and the resumable + response paths call `agentos_sidecar_core::error_response`; +- browser: `crates/agentos-sidecar-browser/src/lib.rs:187-205` calls the same + function after `dispatch_resumable`. + +Therefore the shared variant automatically gives both adapters the same code. +No browser error-enum change is needed. + +One native host conversion must be updated: +`sidecar_to_core_error` at +`crates/agentos-sidecar/src/acp_extension.rs:1812-1846` currently converts an +existing native `SidecarError::SessionNotFound(session_id)` back into shared +`InvalidState`. Map it directly to `AcpCoreError::SessionNotFound(session_id)`. + +The older native-only `error_code` at `acp_extension.rs:3047-3063` and native +sidecar error mapping already use `session_not_found`; preserve them. + +### Client consumption + +Rust decoding at `crates/client/src/session.rs:1592-1621` preserves an ACP error +as `ClientError::Kernel { code, message }`. Then +`send_session_request_with_text` at lines 1285-1308 maps the exact +`session_not_found` code to `ClientError::SessionNotFound(session_id)`. + +Do not add a client session-map lookup, string match, compatibility alias, or +mapping of every `invalid_state` error. + +TypeScript decoding at `packages/core/src/agent-os.ts:2543-2557` constructs an +`Error` with `error.code = response.val.code`. Its flat prompt/state/config APIs +forward to the sidecar, so it will preserve `session_not_found` without a +production edit. + +### Protocol and generated bindings + +The source schema at +`crates/agentos-protocol/protocol/agent_os_acp_v1.bare:198-201` already defines +`AcpErrorResponse { code: str, message: str }`; it does not enumerate error +codes. Rust includes the build-generated definitions through +`crates/agentos-protocol/src/generated.rs`, and the checked-in TypeScript +binding at `packages/core/src/sidecar/agentos-protocol.ts:908-923` already reads +and writes both fields as strings. + +Therefore **do not edit the BARE schema, generated Rust output, or generated +TypeScript protocol file**. Regeneration would produce no semantic change and +would incorrectly enlarge this revision. + +## Exact implementation + +### `crates/agentos-sidecar-core/src/lib.rs` + +Add a variant carrying the session ID, not preformatted message text: + +```rust +pub enum AcpCoreError { + SessionNotFound(String), + // existing variants... +} +``` + +Map it in `code()`: + +```rust +AcpCoreError::SessionNotFound(_) => "session_not_found", +``` + +Format it in `Display`: + +```rust +AcpCoreError::SessionNotFound(session_id) => { + write!(f, "unknown ACP session {session_id}") +} +``` + +Keep the current message so logs, security assertions, and callers retain useful +context. Storing only the ID prevents call sites from inventing different +messages for the same semantic code. + +Optionally add a private engine helper such as +`unknown_session(session_id: &str) -> AcpCoreError` if it materially shortens +the seven call sites; it must only construct the typed variant and must not +perform policy or message classification. + +### `crates/agentos-sidecar-core/src/engine.rs` + +Replace the seven exact `InvalidState(format!("unknown ACP session ..."))` +constructions with `AcpCoreError::SessionNotFound(session_id.to_owned())`. + +Missing and cross-owner lookups must deliberately produce the same variant, +code, and message. This preserves the existing no-existence-oracle property: +an attacker still cannot distinguish "does not exist" from "exists under +another exact owner". + +### `crates/agentos-sidecar/src/acp_extension.rs` + +Change only this conversion arm: + +```rust +SidecarError::SessionNotFound(session_id) => { + AcpCoreError::SessionNotFound(session_id) +} +``` + +Do not modify the ACP wire schema, native/browser dispatch wrappers, client +session registries, or generated protocol bindings. + +## Risks and exact guardrails + +- **Existence leak:** absent and cross-owner session IDs must still produce the + same code and the same requested-ID message. Never classify cross-owner as + `unauthorized`. +- **Over-broad replacement:** change only the seven constructions whose exact + message is `unknown ACP session ...`, plus the native conversion arm. Busy + sessions, malformed adapter data, missing pending interactions, restart + failures, and cleanup failures retain their current codes. +- **Closed-session semantics:** the lookup closures also classify an internal + record with `closed == true`; keep that behavior typed as + `session_not_found`. Close itself remains idempotent. +- **Completion race:** both completion lookups can observe that the target was + removed while a request was in flight. `session_not_found` is still the + correct caller-visible result because the authoritative target no longer + exists; do not invent a client retry or compatibility state machine. +- **Exhaustive matches:** Item 36 has already added `Context` and `Cleanup` to + `AcpCoreError`.

At +`crates/sidecar-client/src/transport.rs:573-620`, +`SidecarTransport::spawn` creates the child and calls: + +```rust +tokio::spawn(run_writer(stdin, control_writer_rx, request_writer_rx)); +tokio::spawn(run_reader(Arc::downgrade(&transport), stdout)); +tokio::spawn(run_silence_watchdog( + Arc::downgrade(&transport), + SIDECAR_SILENCE_TIMEOUT, +)); +``` + +Those tasks belong to the Tokio runtime that happened to call `spawn` first. +The transport stores channels and the child, but no runtime-independent driver. +Dropping that first runtime aborts all three tasks even while another runtime +still holds a live VM and the process-global pool still holds the transport. + +`dispatch_sidecar_request` at `transport.rs:950-982` also uses ambient +`tokio::spawn`. It must run on the same owned transport runtime so a host +callback cannot inherit a short-lived request caller's runtime either. + +### Lease accounting correctly keeps the process, but cannot keep the runtime + +Every VM increments the shared `active_vm_count` in +`AgentOs::create` at `crates/client/src/agent_os.rs:355-359`. Shutdown releases +only that VM's lease. At `agent_os.rs:527-535`, the client kills the connection +and disposes the sidecar only when the count reaches zero. + +That is correct same-process sibling ownership. It creates the observed broken +state when runtime A exits while VM B remains: + +```text +process-global AgentOsSidecar (active_vm_count = 1) + -> cached SharedConnection + -> cached Arc + -> child still retained + -> request/control senders still retained + -> writer/reader/watchdog tasks aborted with runtime A +``` + +VM B's next request reaches `request_wire_with_frame_limit` at +`transport.rs:704-751`. With the writer receiver gone, the send at lines +728-733 returns `sidecar transport closed`. If a response was already enqueued +when the reader disappeared, the waiter instead receives +`sidecar transport disconnected`; the reader's normal tail cleanup at lines +1192-1194 does not run when the task itself is aborted. + +### Cron exposed the bug but does not own it + +The Item 37 tests made the failure visible because each `#[tokio::test]` owns a +separate runtime and both originally called `common::new_vm()` against the same +default pool. Whichever test created the transport first owned its I/O tasks. +If that test completed first, its runtime disappeared while the sibling test's +one-second alarm was firing. + +Cron itself is correctly isolated: + +- each `AgentOs` constructs its own `CronManager` at + `crates/client/src/agent_os.rs:361-376`; +- alarm state, alarm handler, and alarm task are per manager at + `crates/client/src/cron.rs:218-233` and `392-469`; +- cron requests contain connection/session/VM ownership at + `cron.rs:892-898`; and +- the native sidecar validates that ownership and stores schedulers by `vm_id` + at `crates/native-sidecar/src/service.rs:1619-1663` and `1688-1712`. + +The two tests use distinct job IDs. Their host callback IDs both begin at +`host-cron-callback-1`, but those registries are per `CronManager` and their +runs are returned through VM-owned requests. Neither IDs nor timestamp equality +caused the failure. The near-identical timestamps merely make runtime A's exit +race VM B's alarm frequently. + +Item 37 now uses distinct test pools in +`crates/client/tests/cron_e2e.rs:21-22` and `155-156`. Keep that isolation: it +removes cross-test coupling. It is not the product fix for Item 76. + +## Exact recommended production edit + +### `crates/sidecar-client/Cargo.toml` + +Add Tokio's `rt-multi-thread` feature to this crate's existing dependency. Do +not add a new async runtime dependency: + +```toml +tokio = { version = "1", features = [ + "io-util", "macros", "process", "rt", "rt-multi-thread", "sync", "time" +] } +``` + +The workspace already resolves Tokio with this feature through other crates, so +no version or protocol change is needed. Regenerate `Cargo.lock` only if Cargo +actually changes it. + +### `crates/sidecar-client/src/transport.rs` + +1. Import `std::sync::OnceLock` alongside `Arc`/`Weak`. + +2. Add one bounded process-lifetime transport runtime near the transport + constants. Use a fixed worker count (recommended: two) and descriptive + thread names: + + ```rust + const TRANSPORT_RUNTIME_WORKERS: usize = 2; + + static TRANSPORT_RUNTIME: OnceLock> = + OnceLock::new(); + + fn transport_runtime() -> Result<&'static tokio::runtime::Runtime, TransportError> { + TRANSPORT_RUNTIME + .get_or_init(|| { + tokio::runtime::Builder::new_multi_thread() + .worker_threads(TRANSPORT_RUNTIME_WORKERS) + .thread_name("agentos-sidecar-transport") + .enable_all() + .build() + .map_err(|error| error.to_string()) + }) + .as_ref() + .map_err(|error| { + TransportError::Sidecar(format!( + "failed to initialize sidecar transport runtime: {error}" + )) + }) + } + ``` + + Storing the `Runtime`, rather than only an ambient `Handle`, makes ownership + explicit and prevents a caller runtime from determining task lifetime. Two + workers keep the resource bound fixed while ensuring a reader and writer can + progress when a sidecar-request callback is awaiting work. Do not use + `spawn_blocking` or an unbounded thread-per-request design. + +3. Split the current `SidecarTransport::spawn` body into a private + `spawn_on_transport_runtime` async function. It should contain the existing + binary resolution, `Command`, pipes, channels, object construction, and the + three background spawns unchanged. + +4. Make the public `SidecarTransport::spawn` submit that whole function to the + owned runtime and await the join result: + + ```rust + pub async fn spawn(binary_path: Option) -> Result, TransportError> { + transport_runtime()? + .spawn(Self::spawn_on_transport_runtime(binary_path)) + .await + .map_err(|error| { + TransportError::Sidecar(format!( + "sidecar transport startup task failed: {error}" + )) + })? + } + ``` + + Because `spawn_on_transport_runtime` executes inside the owned runtime, its + existing `tokio::spawn` calls bind to that runtime. The child must also be + created there: creating Tokio process pipes on runtime A and moving them to a + different reactor is not a valid fix. + +5. Leave `request_wire*`, event logs, pending bounds, callback maps, ownership + routing, and payload codecs unchanged. Callers continue awaiting ordinary + transport futures on their own runtimes; Tokio MPSC/oneshot/watch channels + are runtime-independent synchronization boundaries. + +6. Keep `kill_child`, `AgentOsSidecar::kill_connection`, and last-lease disposal + semantics. When the final transport `Arc` disappears, its senders and + `kill_on_drop` child close; the owned runtime lets reader/writer cleanup run + instead of aborting it with an unrelated caller runtime. + +No edit belongs in `crates/native-sidecar`, the wire schema, cron, TypeScript, +or Rust VM policy. This is a generic native framed-transport lifetime fix. + +## Deterministic before regression + +Add `crates/client/tests/shared_sidecar_runtime_e2e.rs` as a separate integration +test binary. Do not use timing or default test parallelism to reproduce the +failure. + +The test should be a synchronous `#[test]` that creates two explicit Tokio +runtimes on different OS threads and coordinates them with standard channels: + +1. Choose one unique shared pool name used only by this test. +2. On OS thread/runtime A, create VM A first and signal readiness. This + deterministically makes runtime A create the pooled `SidecarTransport`. +3. On runtime B, create VM B against the same pool. Assert the sidecar IDs are + equal and `active_vm_count == 2`. +4. Signal runtime A to shut down VM A and exit its thread/runtime. Join that + thread before continuing. Assert VM B's sidecar count is now one. +5. Under a short outer timeout, issue a simple real request from VM B, such as + `list_cron_jobs()` or a filesystem round trip. +6. Schedule a near-future VM B host callback, wait under one bounded deadline + for the callback and its terminal event, then cancel it. +7. Shut down VM B normally. + +Against the parent implementation, step 5 deterministically fails with a +transport-closed/disconnected error after runtime A drops. Record that exact +test name, parent revision, and failure in the tracker before applying the fix. +The test must not accept a timeout as success, and its own waits must be bounded +so a missing reader cannot hang CI. + +This test proves more than the original cron race: + +```text +runtime A creates shared process -> runtime B leases same process +runtime A VM closes -> runtime A exits -> runtime B still performs RPC + alarm/wake +``` + +## After tests + +The same deterministic test must pass without serialization or distinct pools +between A and B.

Fix confidence: **high** once +Items 47 and 76 are parents of the revision. + +This work belongs in the clients' native host transport and pool bookkeeping. +An OS parent is the only component that can retain and reap its child process; +the sidecar cannot acknowledge its own host-process death over the protocol. +No VM default, runtime policy, filesystem behavior, permission rule, or guest +process behavior moves into either client. + +## Original issue + +### Rust drops the only child handle before reaping + +`SidecarTransport` owns the spawned Tokio child in +`crates/sidecar-client/src/transport.rs:542-566`.

Cancellation +after the first call leaves the handle in `ready`, with no connection and no +owned child. A retry can publish `disposed`, but it still cannot wait for the +old OS process. + +### Rust create and dispose have no common linearization point + +`AgentOs::create` resolves a pooled handle at +`crates/client/src/agent_os.rs:202-210`, establishes/reuses its process at lines +253-275, initializes the VM at lines 287-347, and increments +`active_vm_count` only at lines 355-359. + +`AgentOsSidecar::dispose` at `crates/client/src/sidecar.rs:230-278` uses atomics +but no lifecycle lock. It sets `disposing`, unconditionally zeros the active +count, publishes `disposed`, and removes the pool entry without terminating or +reaping `connection`. It also does not actually dispose the active leases its +comment claims to drain. + +The gaps are observable: + +```text +create B shutdown/dispose A +-------- ------------------ +reuse old connection +open session / initialize VM + observe active_vm_count == 0 + take connection; start_kill; lose Child + publish disposed; remove pool entry +increment active_vm_count to 1 +return VM B backed by the dead old generation +``` + +Another ordering lets `ensure_connection` install a new child on the old handle +while disposal is publishing it as disposed. `ensure_connection` at +`sidecar.rs:148-197` checks only whether `connection` is populated; it does not +check the sidecar lifecycle state. Pool lookup at lines 398-403 also returns a +`disposing` handle because it excludes only `disposed`. + +### TypeScript can resolve disposal without confirmed exit + +The native child wrapper is in `packages/runtime-core/src/process.ts`. +`StdioSidecarProcess.waitForExit` at lines 100-129 returns `number | null`. +That representation conflates two different outcomes: + +- timeout returns `null`; and +- a real signal exit invokes Node's `exit` listener with `code === null`, so it + also returns `null`. + +`StdioSidecarProtocolClient.dispose` at +`packages/runtime-core/src/native-client.ts:164-213` waits for graceful exit, +sends `SIGKILL` after a timeout, and then ignores the result of the second +`waitForExit` at line 184. It also ignores Node's boolean `child.kill` result; +`false` normally means no signal was sent and does not throw. After either +failure it destroys stdio and returns success. + +The silence callback at `native-client.ts:75-84` repeats the raw, swallowed +`SIGKILL`. Shared-process authentication rollback at +`packages/core/src/agent-os.ts:3377-3392` does the same before clearing the +tracked child/promise. These paths can all abandon a still-running child. + +The synchronous `process.on("exit")` fallback at `agent-os.ts:3257-3279` is +necessarily best effort because Node is already exiting. Keep it as the final +process-exit fallback, but do not use its limitations to justify best-effort +shutdown in an awaited API. + +### TypeScript has the same create/dispose race + +The retained host state is at `packages/core/src/agent-os.ts:3214-3240`. +`leaseAgentOsSidecarVm` checks `ready` synchronously at lines 3548-3553 and +takes an event-loop hold before awaiting creation, but it does not add the +lease to `activeLeases` until lines 3624-3629. + +`AgentOsSidecar.disposeOnce` at lines 3466-3488 sets `disposing` and snapshots +only the leases already in the set. A create paused between the state check and +lease insertion is invisible. Disposal can terminate the shared process and +publish `disposed`; the create then inserts a new active lease into the disposed +handle. The event-loop hold protects Node ref/unref accounting, not lifecycle +serialization. + +`nativeProcess?: Promise` also hides the concrete +client until authentication completes. Disposal and failed-auth cleanup should +retain the spawned generation immediately, not recover it only from a fulfilled +promise. + +## Exact cross-client behavior + +The clients should expose the same state contract: + +- a create that enters the lifecycle gate first may finish and register its + lease; a later explicit dispose must then dispose that lease; +- once explicit disposal enters first, new creates against that handle fail as + `disposing` and pool lookup does not return it as reusable; +- concurrent dispose callers await the same work; +- a termination failure leaves state `disposing`, retains the exact child + generation, and is retryable; +- `disposed` means every authoritative VM close attempted by the handle has + completed and the owned native child has produced a terminal status through + `wait`/Node `exit`; +- the pool admits a replacement only after the prior exact instance reaches + `disposed`; and +- absent an awaited caller, a watchdog/drop-triggered termination continues in + its host supervisor and reports any failure visibly. + +Do not add a protocol `shutdown` acknowledgement for OS-process death. Existing +session/VM close responses remain the authoritative runtime cleanup +acknowledgements; OS exit/reaping is a separate host responsibility. + +## Exact Rust edits + +### `crates/sidecar-client/src/transport.rs` + +Build on Item 76's owned transport runtime. Replace +`parking_lot::Mutex>` with a private, bounded child supervisor: + +1. Move the spawned `Child` into one supervisor task as soon as stdin/stdout are + taken. The task must run on Item 76's process-lifetime runtime, not on an + arbitrary caller runtime. +2. Give the transport a bounded termination-command sender and a shared terminal + result. A command must be enqueued before returning the awaitable result, so + dropping/cancelling that result cannot cancel the supervisor operation. +3. On each command, call `try_wait` first. If already exited, record the status. + Otherwise call `start_kill`, then run `Child::wait` under one fixed, bounded + force-exit deadline. +4. Do not drop the child on signal error or wait timeout. Return a typed + termination failure while the supervisor retains it, allowing the next + command to retry. +5. Once `wait` succeeds, cache a small cloneable terminal record (exit code and + Unix signal) and answer every later termination request with that same + record. Exactly one task performs the reap. +6. Have the reader's EOF tail and `Drop for SidecarTransport` enqueue a + termination/reap request. Drop cannot await, but Item 76's owned runtime lets + the supervisor continue after the transport/caller disappears. + +Recommended API shape (names may vary, semantics may not): + +```rust +pub async fn terminate_child(&self) -> Result; +fn request_child_termination(&self) -> ChildTermination; +``` + +`ChildTermination` is the cancellation-safe awaitable returned after the +bounded command is accepted. Keep `kill_on_drop(true)` only as a final runtime +destruction fallback; it is not the successful disposal path. + +Change `run_silence_watchdog` at current lines 1204-1222 to await +`terminate_child`. Always fail pending requests with the original watchdog +failure. If termination itself fails, emit a structured error with its typed +phase; do not silently replace or discard either failure. + +Change the fail-closed route callback in +`crates/client/src/process.rs:753-763,903-921` to await the same termination +primitive. The helper can become async because its production caller is already +async. Remove every call to the old `kill_child` API. + +### `crates/sidecar-client/src/error.rs` and Rust public mapping + +Add a typed transport termination error rather than another unstructured +string. It needs at least a stable phase (`signal` or `reap_timeout`), the +bounded deadline where relevant, and the underlying message. Map it explicitly +through `crates/client/src/error.rs:76-82` to a typed `ClientError` termination +variant so public `AgentOsSidecar::dispose` callers can distinguish termination +from a sidecar wire rejection. + +The matching TypeScript error is described below. Keep message semantics equal: + +```text +sidecar termination failed during signal: +sidecar termination failed during reap_timeout: no exit after ms following SIGKILL +``` + +No errno or sidecar response code is involved. + +### `crates/client/src/sidecar.rs` + +Add one async lifecycle gate to `AgentOsSidecar`. Its protected operation is +small in concept but spans creation through lease registration and explicit +disposal through confirmed reaping. + +Replace count-only leases with exact host lease records. The smallest Rust +representation is a generated lease ID plus a `Weak` retained by +the sidecar. This avoids an `Arc` cycle while allowing public sidecar disposal +to upgrade and shut down every live VM. Derive `active_vm_count` from the +records (or update the existing atomic only under the same transitions); never +zero it independently of real lease removal. + +Refactor these methods: + +- `ensure_connection` (current lines 148-197) may run only for a `ready` handle + under the lifecycle gate; +- `kill_connection` (199-206) becomes retryable `terminate_connection` and does + not remove `SharedConnection` until `terminate_child().await` succeeds; +- `dispose` (230-278) serializes concurrent callers, sets `disposing`, drains + exact live leases, awaits connection termination, then and only then sets + `disposed` and removes the exact pool entry; +- lease disposal (281-310) removes its exact record once and reports the + remaining count; and +- `get_shared_sidecar` (390-443) returns only `ready` entries. If it sees + `disposing`, release the process-global map lock, await/retry that exact + handle's disposal, then loop. Never hold `SHARED_SIDECAR_POOL_LOCK` across an + await and never install a second generation beside a disposing one. + +Preserve the existing exact-instance pool removal check. Add a private +`dispose_if_idle` for Rust's current last-lease behavior: after taking the +lifecycle gate it must re-check that no create registered a lease. Public +`dispose` drains leases; `dispose_if_idle` returns without terminating when a +concurrent create linearized first. + +### `crates/client/src/agent_os.rs` + +In `AgentOs::create`, serialize only after all explicit input has been validated +and serialized, but before `ensure_connection`. Hold the sidecar lifecycle gate +through open-session/VM initialization and insertion of the exact weak lease +record. This gives disposal one unambiguous before/after point without moving +configuration logic into the client. + +Keep the existing sidecar-owned initialization transaction and failure rollback. +Do not add a client VM state machine. A cancelled create drops the lifecycle +guard; any response that establishes a session must continue to use retained +transport response correlation/sidecar idempotent close rather than a detached +client registry. + +In `shutdown` at current lines 517-538, release the exact lease and call +`dispose_if_idle` only when the release reports zero leases **and** the sidecar +is still `ready`. When public sidecar disposal has already set `disposing`, it +owns final termination; the nested VM shutdown must not reacquire the same gate +and deadlock. The shutdown attempt remains incomplete until whichever owner is +responsible confirms child reaping. If its caller is cancelled while awaiting +termination, the child supervisor continues; the next idempotent shutdown +awaits the same result. + +## Exact TypeScript edits + +### `packages/runtime-core/src/process.ts` + +Change `waitForExit` to return a terminal record or a distinct timeout: + +```ts +interface SidecarExitStatus { + exitCode: number | null; + signal: NodeJS.Signals | null; +} + +waitForExit(timeoutMs: number): Promise +``` + +An `exit`/`close` event with `code === null` and a signal is a non-null terminal +record. Only expiry of the timer returns `null`. + +Add one retryable `terminate` method/promise to `StdioSidecarProcess`: + +- wait for the requested graceful interval when disposal closed stdin; +- re-check terminal metadata before and after signaling; +- treat `child.kill("SIGKILL") === false` as `signal` failure unless the child + concurrently reached a terminal state; +- after a successful signal, require a non-null exit record within the force + deadline; +- on signal failure or timeout, clear only the attempt promise and retain the + child/stdio for retry; and +- cache success so watchdog, disposal, and rollback converge on one exit. + +### `packages/runtime-core/src/native-client.ts` and `sidecar-errors.ts` + +Add `SidecarTerminationError` with the same `signal | reap_timeout` phase and +message contract as Rust. + +Refactor `StdioSidecarProtocolClient.dispose` at current lines 164-213 to call +the process termination primitive. Destroy protocol streams only after exit is +confirmed. Preserve the existing nonzero natural-exit diagnostic, but do not +mistake a signal status for a timeout. + +The silence callback at lines 75-84 must start that same force-termination +attempt. The pending request still receives `SidecarSilenceTimeout`; a +termination failure is stored for a later `dispose` retry and reported to +stderr immediately. There must be no empty catch or floating rejected promise. + +### `packages/core/src/agent-os.ts` after Item 47 + +Item 47 removes the synthetic `AgentOsSidecarClient` state machine and leaves +the real VM-admin lease, `activeLeases`, native process, event-loop holds, and +public sidecar state. Put the Item 77 lifecycle gate around that direct lease; +do **not** add the deleted session/VM maps back. + +Use a small FIFO promise gate stored in `AgentOsSidecarState`. Run the direct +`createVmAdmin` factory through successful `activeLeases` insertion under that +gate. Run `AgentOsSidecar.disposeOnce` through the same gate. JavaScript promises +are not caller-cancellable, so the operation continues once enqueued. + +Change the native generation from an opaque fulfilled-only promise to an +immediately retained record, for example: + +```ts +interface SharedSidecarNativeGeneration { + client: SidecarProcess; + session: Promise; +} +``` + +This lets authentication rollback and concurrent disposal terminate the exact +spawned client even before authentication resolves. Clear the generation and +`sharedChild` only after `client.dispose()` confirms process exit. On failure, +retain both, leave the handle `disposing`, and let the next dispose call retry. + +Make `getSharedAgentOsSidecarInternal` and `resolveAgentOsSidecar` async (their +public callers already return promises). Never return a `disposing` handle as +reusable and never replace it in `sharedSidecars` before confirmed disposal. + +Keep `eventLoopHolds`: it is valid Node host state. The lifecycle gate prevents +dispose/create races; the hold still independently controls whether live work +keeps Node's event loop referenced. + +## Deterministic before tests + +Record failures against Item 77's parent before editing production code. + +### Rust + +In the `agentos-sidecar-client` transport unit tests, spawn a long-lived child, +install it in the current transport, call `kill_child`, and assert the transport +still owns a waitable child until reaping completes. The parent fails +immediately because `child.lock().is_none()` as soon as `kill_child` returns. +This is deterministic source behavior; do not use a sleep as proof of a zombie. + +Add a real-client lifecycle regression with a unique pool and a blocking +`sidecar_js_bridge_callback` during `InitializeVm`: + +1. start VM B creation and wait until the callback proves initialization is in + flight but the lease count is still zero; +2. start disposal of the same explicit/shared sidecar; +3. assert it cannot publish `disposed` or remove/install a pool generation; +4. release the callback and observe the chosen linearization; and +5. prove no returned VM is attached to a killed/disposed generation. + +The current implementation publishes `disposed` while creation is paused and +can later increment the disposed handle's count. + +### TypeScript + +In `packages/runtime-core/tests/process.test.ts`, use +`StdioSidecarProcess.fromChild` with an EventEmitter-backed fake child. Emit +`exit(null, "SIGKILL")` and assert `waitForExit` reports a terminal signal +record. The current `number | null` API returns the same `null` used for timeout. + +In `packages/runtime-core/tests/native-client.test.ts`, run a fixture that stays +alive after stdin EOF, stub `child.kill` to return `false`, and use short test +grace/force deadlines. Assert `dispose()` rejects and the child is still owned. +The current implementation resolves success. Restore the real kill in `finally` +so the test itself cannot leak a process. + +Add a controlled direct-VM factory regression after Item 47: pause creation +before lease insertion, call `sidecar.dispose()`, and assert `disposed` is not +published while the create is invisible. The current code snapshots an empty +`activeLeases`, disposes the process, and later inserts into the disposed state. + +## After tests + +### Rust transport + +Add focused `crates/sidecar-client` tests for: + +- dropping a termination awaiter after its command is accepted, then awaiting a + second request and observing the same reaped terminal record; +- watchdog and explicit termination commands overlapping, with one signal/reap + and equal completion; +- injected signal failure and reap timeout retaining the child for a successful + retry; and +- reader EOF and transport drop enqueuing supervisor cleanup. + +Use a small private child-driver test seam for the otherwise unforceable OS +failure branches. Do not add a public mock process API or poll `/proc` as the +definition of reaping; successful `Child::wait` is the proof. + +### Rust pool/client + +Add `crates/client/tests/sidecar_lifecycle_e2e.rs` using the blocking bridge +callback above. Cover both orderings: + +- create linearizes first: it registers one exact lease, then explicit disposal + closes it and reaps the child before `Disposed`; +- dispose linearizes first: a later create is rejected while disposing and a + replacement pool handle appears only after the old child is reaped. + +Cancel/drop the first termination waiter after the supervisor accepts the +command and prove retry completes. Assert the pool contains no old-generation +entry and no child remains owned after success. + +Keep Item 76's two-runtime regression and `sidecar_pool_e2e` green. + +### TypeScript + +Extend `process.test.ts` and `native-client.test.ts` to cover: + +- graceful numeric exit, signal exit, and true timeout as distinct results; +- `kill() === false`, thrown kill, and force-exit timeout as typed retryable + failures; +- retry after failure, with streams/generation retained until exit; and +- silence-watchdog and explicit dispose convergence on one terminal result. + +After Item 47, add `packages/core/tests/sidecar-lifecycle.test.ts` (or extend its +direct-lease acceptance test) with a deferred real-admin factory. Assert create +and dispose order, exact lease count, no second generation while disposing, and +`disposed` only after the fake child exit promise resolves. Do not restore the +synthetic lifecycle classes merely to make the test injectable. + +Retain the real placement, disposal-retry, sibling-ownership, and clean-exit +suites. + +## Risks and guardrails + +- **Item 76 runtime ownership is mandatory.** A perfect supervisor spawned on a + caller's Tokio runtime is still aborted when that runtime exits. +- **Never hold the process-global Rust pool lock across await.** Clone the exact + disposing handle, release the lock, await it, then retry lookup. +- **No `Arc` cycle.** Rust sidecar lease records must be weak references; the VM + already strongly owns its sidecar handle. +- **No replacement-before-reap.** Removing the cache entry on `disposing`, + signal send, stdin close, or timeout can run two native generations for one + pool. +- **Retain ownership on failure.** Do not clear Rust `SharedConnection`, the + supervisor child, TypeScript `nativeProcess`, `sharedChild`, or stdio until + terminal exit is confirmed. +- **Bound every wait.** Grace and force deadlines remain fixed host-transport + constants. A timeout is a typed failure and retry point, not permission to + claim success. +- **Preserve original failures.** Watchdog requests still fail with silence + timeout and startup still reports authentication/creation failure; append or + aggregate termination failure without replacing the initiating error. +- **Process-exit hook exception.** Node's synchronous host-exit hook cannot + await. It remains a final best-effort `SIGKILL`, but no awaited API may copy + that behavior. +- **Do not add PID polling.** Use Node `exit`/`close` and Tokio `Child::wait`, + matching native Linux parent/child behavior. +- **Do not broaden into guest process policy.** This item terminates the one + trusted native sidecar child.

The authoritative kernel root +and the sidecar's shadow/native-root helpers currently use two different +bootstrap implementations. Give the kernel root a lowest-priority standard +root layer, with path-specific modes, and make the native sidecar reuse the same +bounded directory table. + +The important layering order is: + +```text +explicit bootstrap upper + -> caller-provided lowers + -> bundled base image (unless disabled) + -> standard AgentOS/Linux root fallback +``` + +The fallback must be lower than the bundled base. That makes it fill missing +mountpoints such as `/etc/agentos` and `/usr/local/bin` without changing real +base-image metadata such as `/tmp` `01777`, `/root` `0700`, or the ownership of +`/workspace`. + +When the bundled base is disabled and the caller supplied no lower, that same +fallback is the minimal root.

Changing `FilesystemEntry::directory` itself would be wrong because +it is also the generic default for explicit caller-created directories. + +The minimal table also lacks `/home/agentos` and `/workspace`, even though the +native shadow-root table and the default VM cwd contract include them. That is +an untested instance of the same split and should be corrected while the table +is made authoritative. + +### `SHADOW_ROOT_BOOTSTRAP_DIRS` is real, but not the kernel root + +`crates/native-sidecar/src/vm.rs` declares the modes the failing tests expected: + +```rust +("/tmp", 0o1777), +// ... +("/usr/local/bin", 0o755), +("/var/tmp", 0o1777), +("/etc/agentos", 0o755), +("/workspace", 0o755), +``` + +That table is used only by: + +- `bootstrap_shadow_root`, which prepares the host shadow tree used by mapped + native execution; and +- `bootstrap_native_root_filesystem`, which prepares an explicitly configured + native root plugin. + +Normal overlay VMs use `RootFileSystem` from the VFS crate. `vm.stat()` and +`vm.exists()` therefore report the VFS root, not the shadow tree. The table is +not dead, but the existing comments and Item 2 explanation incorrectly imply +that it also seeds the normal kernel root. + +## Are the tests or production stale? + +**Production is wrong for the two asserted behaviors.** `/tmp` `01777` is a +standard Linux/container invariant and is required for normal multi-process +temporary-file behavior. `/usr/local/bin` is already on the sidecar-owned +default `PATH`, so providing the directory is internally consistent. + +`/etc/agentos` is product-specific rather than a generic Linux directory, but +the runtime still reserves and protects that subtree in +`crates/kernel/src/kernel.rs` and native shadow synchronization. Until that +reserved subtree is deliberately removed as a separate product decision, the +sidecar-owned root contract should provide its mountpoint consistently. An +empty directory is not a reason to restore client bootstrap. + +The prose at the top of +`packages/core/tests/kernel-bootstrap-base.test.ts` **is stale**. The bundled +base does not provide every POSIX/AgentOS directory, and there is no generic +"host-side bootstrap emits nothing" rule. Rewrite the comment to describe a +low-priority fallback layer that fills gaps without clobbering higher-layer +metadata. The assertions themselves should remain and be broadened. + +## Exact production edits + +### 1. `crates/vfs/src/posix/root_fs.rs` + +Replace the string-only private `DEFAULT_ROOT_DIRECTORIES` with one bounded, +exported path/mode table. A suitable name is +`AGENTOS_ROOT_BOOTSTRAP_DIRECTORIES`; it should exclude `/` so native-root and +host-shadow loops can consume it safely. + +Retain the existing bounded path set, and include the two currently shadow-only +working directories: + +```rust +pub const AGENTOS_ROOT_BOOTSTRAP_DIRECTORIES: &[(&str, u32)] = &[ + ("/dev", 0o755), + ("/proc", 0o755), + ("/tmp", 0o1777), + // existing standard paths, each with its intentional mode + ("/home/agentos", 0o755), + ("/usr/local/bin", 0o755), + ("/var/tmp", 0o1777), + ("/etc/agentos", 0o755), + ("/workspace", 0o755), +]; +``` + +Do not broaden Item 78 into an unreviewed base-image metadata rewrite. The +bundled base already has additional intentional metadata (`/root` `0700`, +`/sys` and `/var/empty` `0555`, `/home/agentos` `02755`, and user ownership for +`/home/agentos` and `/workspace`). Higher-layer precedence must preserve it. +The fallback table should initially preserve the existing sidecar table's +no-base modes except for the already-declared sticky directories. + +Build `minimal_root_snapshot` from an explicit `/` entry plus that table, set +each entry's mode from the tuple, then retain the existing empty `/usr/bin/env` +fallback. Do not special-case generic `FilesystemEntry::directory`. + +Change lower selection to append the standard fallback below the base: + +```rust +let mut lower_snapshots = descriptor.lowers.clone(); +if !descriptor.disable_default_base_layer { + lower_snapshots.push(load_bundled_base_snapshot_with_limits(limits)?); + lower_snapshots.push(minimal_root_snapshot()); +} else if lower_snapshots.is_empty() { + lower_snapshots.push(minimal_root_snapshot()); +} +``` + +This intentionally preserves the current meaning of an explicit custom root: +when the default base is disabled and at least one caller lower is supplied, +the caller owns that lower's shape. It also avoids silently increasing the +minimum inode count of custom roots and breaking the existing small import-limit +tests. The ordinary no-base/no-lower VM still gets a viable Linux root. + +The fallback is trusted and bounded, but it is a real lower layer. Keep it in +`validate_descriptor_import_limits` so its inode/memory cost remains visible to +resource limits. + +### 2. `crates/native-sidecar/src/vm.rs` + +Import `AGENTOS_ROOT_BOOTSTRAP_DIRECTORIES` through +`agentos_kernel::root_fs` and delete the duplicate +`SHADOW_ROOT_BOOTSTRAP_DIRS` constant. Use the shared table in both +`bootstrap_shadow_root` and `bootstrap_native_root_filesystem`. + +This is the only native-sidecar change required. Do not copy the fallback into +`create_vm`, do not generate protocol bootstrap entries, and do not run these +operations after guest permissions are active. + +### 3. Confirmed adjacent dead base staging + +`crates/native-sidecar/build.rs` copies a second +`assets/base-filesystem.json` into `OUT_DIR`, but no native-sidecar Rust source +includes or reads that staged file. The authoritative parser is +`crates/vfs/src/posix/root_fs.rs`, which embeds the VFS crate's asset. The two +committed JSON assets are byte-identical today. + +After the root fix is green, remove the unused native-sidecar build script and +duplicate asset, and remove the corresponding native-sidecar copy from the +"Stage vendored V8 bridge bundles and base filesystem" publish step. Keep the +VFS asset and the VFS build script: the latter also stages the package-format +schema and is not dead. This cleanup is high-confidence but separable if the +main Item 78 diff must stay minimal. + +## Exact tests + +### Before behavior already recorded + +Keep the current real-client gate as the before test: + +```bash +cargo build -p agentos-sidecar --bin agentos-sidecar +AGENTOS_SIDECAR_BIN="$PWD/target/debug/agentos-sidecar" \ + pnpm --dir packages/core exec vitest run \ + tests/kernel-bootstrap-base.test.ts --fileParallelism=false +``` + +Expected parent result: **1 passed, 2 failed**. The base `/tmp` test passes; +the gap-fill test fails at `/etc/agentos`; the no-base mode comparison receives +`0755` instead of `01777`. + +### Sidecar/runtime tests after the fix + +1. In `crates/vfs/tests/posix_root_fs.rs`, add + `default_root_fallback_fills_base_gaps_without_clobbering_base_metadata`. + Create the default descriptor and assert: + - `/etc/agentos` and `/usr/local/bin` exist at `0755`; + - `/tmp` and `/var/tmp` remain `01777` from the higher base; + - `/root` remains `0700`; and + - `/workspace` remains uid/gid `1000`, proving the fallback did not copy up + or replace base metadata. +2. In the same file, add + `minimal_root_uses_standard_directory_modes_without_the_base`. Disable the + base with no lowers and assert `/tmp` and `/var/tmp` are `01777`, while + `/etc/agentos`, `/usr/local/bin`, `/home/agentos`, and `/workspace` exist. +3. Add or extend a custom-lower test to prove + `disable_default_base_layer: true` plus an explicit lower does not acquire + the fallback and that explicit bootstrap directory metadata still wins. + This freezes the scoped semantics above and protects the import-limit tests. +4. Extend `bootstrap_shadow_root_seeds_standard_directories` in + `crates/native-sidecar/src/vm.rs` to iterate the shared table and check every + path exists. Retain the explicit `/tmp` `01777` assertion. +5. Extend the native-root plugin test in the same module to stat `/tmp` after + `bootstrap_native_root_filesystem` and assert `01777`; this proves the + second consumer of the shared table. +6. Extend + `create_vm_bootstrap_needs_no_guest_filesystem_rights` in + `crates/native-sidecar/tests/service.rs`. Under `PermissionsPolicy::deny_all`, + assert the kernel root contains `/etc/agentos`, `/usr/local/bin`, and + `/workspace`, and that `/tmp` is `01777`; retain the post-readiness `EACCES` + write assertion. This is the authoritative proof that bootstrap does not + require guest rights. +7. Add a small browser-sidecar service regression using a no-base/no-lower + root and its root snapshot. Assert the `/tmp` snapshot entry has mode + `01777` and the same gap directories exist. Browser and native share the VFS + root constructor, but this locks the adapter path to that implementation. + +### Real client black-box gate after the fix + +Update `packages/core/tests/kernel-bootstrap-base.test.ts` rather than adding +client implementation logic: + +- replace the stale header comment; +- check the same directory list and `/tmp`/`/var/tmp` modes in a table-driven + helper for both default and no-base/no-lower VMs; and +- keep this as a black-box protocol gate only. All detailed behavior tests live + in the sidecar/VFS suites above. + +No Rust client-specific implementation test is needed for the defaults.

Use the trusted seam for native sidecar-owned mounts + +Edit `crates/native-sidecar/src/vm.rs`: + +- In `shutdown_configured_mounts()`, replace + `vm.kernel.unmount_filesystem(&existing.guest_path)` with the operator API. + This helper is reached from both disposal and `ConfigureVm` reconciliation; + both are trusted client/sidecar operations under the repository trust model, + so neither should depend on executor permissions. +- Correct the stale comment in + `dispose_vm_internal_outcome_with_event_limit()`: `continue_on_error` means + "attempt every mount", not "the helper cannot return Err". Preserve genuine + unmount/plugin/audit errors in the aggregated disposal failure; do not silence + them. + +No TypeScript fallback, permission override, bootstrap mkdir, or client cleanup +logic should be added.

Converge the browser's existing trusted bypass on the same API + +Edit `crates/native-sidecar-browser/src/service.rs`: + +- `rollback_projected_package_mounts()` currently reaches through three layers + (`filesystem_mut().inner_mut().inner_mut().unmount(path)`) to perform the same + trusted bypass. Replace that with `unmount_filesystem_for_operator(path)`. +- Browser VM disposal itself removes/drops the kernel and is already independent + of guest filesystem policy; no new guest-policy mutation is needed there. + Add lifecycle coverage so native/browser parity is explicit and future + cleanup changes cannot reintroduce the dependency. + +An optional follow-up, not required to close this item, is a symmetric +operator-mount API for `mount_leaf_descriptors()`. Native configure currently +temporarily installs allow-all while doing broader sidecar-owned discovery and +mount reconciliation.

The original regression only demonstrates +an absolute execute `cwd` beneath `vm.host_cwd` being translated and created in +the guest. The same design also lets an untrusted JavaScript guest name a raw +host JavaScript file in `child_process`: `prepare_javascript_shadow` can read +that host path directly, copy it into the VM shadow, and execute it without a +`host_dir` mount. This crosses the declared sidecar-to-executor security +boundary, not merely an SDK-thinness boundary. + +The target rule should be simple: + +- every `cwd`, command path, and file entrypoint arriving from Execute or a + guest child-process request is a **guest Linux path**; +- relative paths resolve against the applicable guest cwd; +- an absent guest path returns its Linux errno; +- a host path is reachable only through an explicit `host_dir` mount, after + which the request still names the mount's guest path; +- host paths used internally to launch V8, Pyodide, or Wasmtime are derived + from an already-authorized guest path, never from the original specifier. + +## Why the current behavior is unsafe + +The top-level cwd flow in `crates/native-sidecar/src/execution.rs` is: + +```text +Execute.cwd + -> resolve_execution_cwds + -> if absolute and beneath vm.host_cwd: + strip the host prefix, invent a guest path, retain the raw host cwd + -> validate_or_materialize_execution_cwd + -> if the guest path is absent but the host directory exists: + mkdir the guest path +``` + +Entrypoints have a parallel path: + +```text +absolute entrypoint + -> resolve_host_entrypoint_within_vm_host_cwd + -> translate host path to guest path + -> prepare_javascript_shadow + -> materialize_host_path_to_shadow +``` + +There is an even broader fallback in `prepare_javascript_shadow`: if the guest +entrypoint is absent, any absolute `resolved.entrypoint` that exists on the +host is passed to `materialize_host_path_to_shadow`. The helper calls raw +`symlink_metadata`, `read_link`, or `fs::read` and then writes the result into +the VM shadow. It does not require a mount and is reachable from +`resolve_javascript_child_process_execution`, so hostile guest code can request +`node /some/host/secret.mjs` or spawn an absolute `.js` command. The existing +`execute_rejects_host_only_absolute_command_path` test covers only a top-level +shell-like command outside the VM host cwd; it does not exercise this +JavaScript path. + +## Exact production edits + +All paths below are in `crates/native-sidecar/src/execution.rs` unless stated +otherwise. + +### 1. Make top-level cwd resolution guest-only + +Replace `resolve_execution_cwds`' three-value result with a two-value result: + +```rust +fn resolve_execution_cwds( + vm: &VmState, + value: Option<&str>, +) -> Result<(String, PathBuf), SidecarError> { + let guest_cwd = resolve_guest_execution_cwd(vm, value)?; + let host_cwd = resolve_vm_guest_path_to_host(vm, &guest_cwd); + Ok((guest_cwd, host_cwd)) +} +``` + +Delete all of the following: + +- the `Path::is_absolute` / `path_is_within_root(vm.host_cwd)` branch; +- the `allow_host_path_overrides` boolean; +- the special `value.is_none() => vm.host_cwd.clone()` branch; +- `validate_or_materialize_execution_cwd`'s host-directory fallback. + +Use `vm.kernel.validate_process_cwd(&guest_cwd).map_err(kernel_error)` directly +in `resolve_execute_request` and `resolve_command_execution`. Item 42 already +added this Linux `chdir` validation; Item 80 should preserve it while deleting +the compatibility `mkdir`. + +This makes an absolute host-looking cwd ordinary guest input. For example, +`/tmp/agentos-fixture/work` means exactly that guest path. It succeeds only if +that path exists in the VFS (including through a mount), otherwise it returns +`ENOENT`. + +### 2. Delete top-level entrypoint translation + +In all three entrypoint branches in `resolve_execute_request` and +`resolve_command_execution`: + +- direct `runtime + entrypoint`; +- `node `; +- direct `.js` / `.mjs` / `.cjs` command; + +delete `requested_host_entrypoint`, `host_entrypoint_override`, the +`allow_host_path_overrides` gates, and the `"outside sandbox root"` errors. +Delete `resolve_host_entrypoint_within_vm_host_cwd` after its remaining shadow +caller is removed. + +Resolve the specifier exactly once with `guest_entrypoint_for_specifier` (or +`resolve_guest_path` for a required path), put that guest path in +`AGENTOS_GUEST_ENTRYPOINT`, and validate it through the kernel before process +admission. Do not place the caller's raw absolute string into an engine +`module_path` or `file_path`. + +The clean implementation is one helper shared by top-level and child path +branches: + +```rust +fn resolve_existing_guest_entrypoint( + vm: &mut VmState, + guest_cwd: &str, + specifier: &str, +) -> Result { + let guest_path = resolve_path_like_guest_specifier(guest_cwd, specifier); + vm.kernel.lstat(&guest_path).map_err(kernel_error)?; + Ok(guest_path) +} +``` + +Code/eval modes (`node -e`, Python `-c`, Python `-m`, stdin, and interactive +mode) must remain exempt because their entrypoint field is source or a module +selector, not a filesystem path. + +### 3. Derive engine host paths only from the VFS + +Delete the raw-host branch in `prepare_javascript_shadow` and then delete its +now-dead helpers: + +- `materialize_host_path_to_shadow`; +- `sync_shadow_entrypoint_into_kernel`. + +`prepare_javascript_shadow` should only: + +1. read the normalized guest entrypoint from `AGENTOS_GUEST_ENTRYPOINT`; +2. return immediately for an explicit `host_dir` mount; +3. otherwise call `materialize_guest_path_to_shadow`, which reads through the + kernel VFS and therefore honors mounts, symlink rules, permissions, and + Linux errno. + +Also remove the `vm.host_cwd` allowance from +`load_javascript_entrypoint_source`. Kernel VFS reads are authoritative. If a +host-side fallback remains for a staged runtime file, restrict it to `vm.cwd` +(the sidecar-owned shadow root) only; never accept `vm.host_cwd` or the original +specifier as another trusted root. + +WebAssembly needs an explicit staging adjustment because the engine consumes a +host module path. Before `CreateWasmContextRequest`, resolve/realpath the guest +entrypoint in the kernel, then: + +- use `host_mount_path_for_guest_path` when it is backed by an explicit + `host_dir` mount; or +- call `materialize_guest_path_to_shadow` and use + `shadow_path_for_guest(vm, guest_path)`. + +The existing AgentOS-package Wasm staging can be generalized or reused, but the +host path must always be derived from the validated guest path. Otherwise +removing only the JavaScript fallback would leave direct Wasm requests passing +raw host-looking strings to Wasmtime. + +### 4. Make guest child cwd and entrypoint resolution identical + +In `resolve_javascript_child_process_execution`: + +- replace the cwd tuple/override state machine with + `resolve_guest_path(parent_guest_cwd, cwd)`; +- derive `host_cwd` with + `host_runtime_path_for_guest_path_with_env` (explicit mount/runtime mapping) + or `shadow_path_for_guest`; inheritance may retain `parent_host_cwd` only + when the guest cwd is unchanged; +- remove the absolute-path-within-`parent_host_cwd` translation; +- remove the relative `parent_host_cwd.join(cwd)` override; +- remove the `vm.host_cwd` fallback; +- replace both child spawn sites' `validate_or_materialize_execution_cwd(..., + true)` with kernel-only cwd validation. + +For path-like child commands and `node `, resolve and validate the +guest entrypoint first. The host execution path may then come only from the +explicit runtime guest-path mapping or the VM shadow. Remove the fallback that +uses an absolute `guest_entrypoint` directly as a host `PathBuf`. + +This child path is essential to Item 80's completion: top-level requests are +sent by the trusted client, but child-process requests originate from the +untrusted executor. + +### 5. Remove legacy external-cwd host synchronization + +The compatibility cwd becomes observable after execution because +`sync_active_process_host_writes_to_kernel` and +`sync_process_host_writes_to_kernel` recursively import a process host cwd when +it lies outside `vm.cwd`. Once every process host cwd is either the VM shadow or +an explicit mount, that whole external-root synchronization path is obsolete. + +Delete: + +- `collect_active_process_host_sync_roots`; +- `collect_process_host_sync_roots`; +- the out-of-shadow branch in `sync_process_host_writes_to_kernel`; +- the loop over `extra_roots` in `sync_active_process_host_writes_to_kernel`. + +Keep ordinary shadow-root reconciliation if the runtime still requires it. +`host_dir` writes are already performed by `HostDirFilesystem`; recursively +copying the mount's host root back into the kernel is neither needed nor the +right enforcement path. + +### 6. Adjacent VM-create ambiguity should be fixed with this item or tracked + +`crates/native-sidecar/src/vm.rs::resolve_vm_cwds` still treats every absolute +`CreateVmConfig.cwd` as a host path, even though `agentos-vm-config` validates +and documents it as a guest path and the SDKs forward it as such. This is why +many native fixtures currently establish `vm.host_cwd` by putting a temp host +directory in metadata `cwd`. + +The consistent fix is: + +```rust +fn resolve_vm_cwds( + configured_cwd: Option<&String>, + shadow_root: &Path, +) -> Result<(String, PathBuf), SidecarError> { + let guest_cwd = resolve_guest_cwd(configured_cwd); + Ok(( + guest_cwd.clone(), + shadow_path_for_guest(shadow_root, &guest_cwd), + )) +} +``` + +Then delete `resolve_host_path` if it has no other caller. Host workspaces must +be mounted, not smuggled through VM `cwd`. If the main implementation keeps +this out of Item 80, create a separate tracked P1 item; otherwise the public VM +cwd contract remains host-dependent and migrated tests can accidentally retain +the old root through another entrypoint. + +## Fixture and caller migration inventory + +The largest source is +`crates/native-sidecar/tests/support/mod.rs`: + +- `create_vm_wire_with_metadata` injects the host temp directory as metadata + `cwd`; +- `execute_wire` serializes an `&Path` host entrypoint directly; +- `create_vm`, `create_vm_with_metadata`, and `execute` wrap those behaviors. + +Change the execute helpers to accept a guest `&str`. Add a test helper that +builds an explicit mount such as: + +```rust +MountDescriptor { + guest_path: String::from("/workspace"), + read_only: Some(false), + plugin: MountPluginDescriptor { + id: String::from("host_dir"), + config: Some(json!({ + "hostPath": host_workspace, + "readOnly": false, + }).to_string()), + }, +} +``` + +Create the VM with omitted cwd (exercising the `/workspace` default) or an +explicit guest cwd, initialize/configure this mount, and execute +`/workspace/`. Read-only probes should use a read-only mount unless the +test intentionally observes writes. + +Every current caller of the host-serializing `execute_wire` helper must migrate; +the affected files are: + +- `builtin_completeness.rs`, `builtin_conformance.rs`; +- `crash_isolation.rs`, `process_isolation.rs`, `session_close.rs`, + `vm_lifecycle.rs`; +- `fetch_via_undici.rs`, `fs_watch_and_streams.rs`, `guest_identity.rs`; +- `kill_cleanup.rs`, `signal.rs`, `socket_state_queries.rs`, + `posix_compliance.rs`; +- `posix_path_repro.rs`, `promisify_module_load.rs`, `security_audit.rs`, + `security_hardening.rs`; +- `node_modules_host_mount_resolution.rs` and + `node_modules_symlink_resolution.rs`. + +`posix_path_repro.rs`, `security_audit.rs`, +`node_modules_host_mount_resolution.rs`, and +`node_modules_symlink_resolution.rs` already send nonempty mount patches. Their +mount lists must include the workspace mount instead of replacing it; do not +hide implicit remounting inside `execute_wire` because that would erase or +reorder the mount topology the test intends to exercise. + +Additional direct host-entrypoint fixtures that do not solely rely on +`execute_wire` occur in: + +- `security_hardening.rs` (direct JavaScript entrypoint and nested host cwd); +- `signal.rs` (direct entrypoint request); +- `python.rs` (custom Python execute helpers); and +- `service.rs` (direct Python/Wasm entrypoint requests and Item 42's + `host-nested` cwd regression). + +Custom VM-create helpers that inject a host directory into metadata `cwd` occur +in `builtin_conformance.rs`, `guest_identity.rs`, `fs_watch_and_streams.rs`, +`python.rs`, and `security_hardening.rs`, in addition to the shared support +helper. Non-execution fixtures using the same legacy pattern also exist in +`connection_auth.rs`, `session_isolation.rs`, `kill_cleanup.rs`, +`layer_management.rs`, and `stdio_binary.rs`; they should use an omitted/guest +cwd even if they do not need a workspace mount. + +Expected assertion updates include `guest_identity.rs` and security probes that +currently expect `process.cwd()` / `PWD` to be `/` only because a host metadata +cwd is translated to the guest root. Mounted workspace executions should expect +`/workspace` (or their explicit guest cwd). + +## Before/after test checklist + +### Characterize before deletion + +- [ ] Keep Item 42's current regression: create a directory only below + `vm.host_cwd`, send the absolute host path as Execute `cwd`, and prove the old + code starts the process and manufactures a guest directory. +- [ ] Add a direct-entrypoint escape regression in `security_hardening.rs`: + create a valid host-only `.mjs` outside every mount, send its absolute path as + a JavaScript entrypoint, and prove the old sidecar reads/executes it. +- [ ] Add an untrusted child regression: execute a guest script from an explicit + `/workspace` mount, have it run `node `, and prove the + old child path exposes a unique host-only sentinel. +- [ ] Add the equivalent direct Wasm characterization if the engine accepts the + raw host module path; this guards the non-JavaScript engine path. + +### Validate after deletion + +- [ ] Convert the Item 42 host-cwd regression: the same absolute string is an + ordinary guest path and returns `kernel_error` with `ENOENT`; assert no guest + directory and no active/retained process were created. +- [ ] Direct host-only JavaScript, Python-file, and Wasm entrypoints return + Linux errno before process admission, never emit the sentinel, and leave no + engine context/process. +- [ ] A guest child `node ` returns `ENOENT`, never executes or + copies the file, and leaves no child route. +- [ ] A relative and absolute guest cwd both succeed when present; a missing + cwd returns `ENOENT`, a file cwd returns `ENOTDIR`, and no case creates it. +- [ ] The same fixture succeeds at `/workspace/entry.mjs` with an explicit + `host_dir` mount. Assert argv/PWD/cwd are guest paths while intentional host + writes appear only under the mounted directory. +- [ ] Read-only `host_dir` entrypoints load successfully and writes return + `EROFS`/`EACCES` through the VFS rather than falling back to a shadow copy. +- [ ] Nested JavaScript `child_process`, Python subprocess, and Wasm command + paths retain guest cwd and explicit-mount behavior. +- [ ] Run the complete native sidecar service, security-hardening, builtin, + POSIX, Python, signal, process/session lifecycle, filesystem, and mount suites. +- [ ] Add or retain one native/browser conformance case showing that a + host-looking absolute string has identical guest-path semantics in both + adapters. + +## Risks and implementation order + +1. Add the escape regressions first. They prevent a partial fix that deletes + cwd translation but leaves raw-host entrypoint materialization. +2. Add the explicit workspace-mount test helper and migrate fixtures. This + separates intended host fixture access from the compatibility code before + production deletion. +3. Delete top-level and child cwd translation/materialization. +4. Delete raw-host entrypoint translation/materialization and add VFS-derived + Wasm staging. +5. Remove external-cwd host sync and the VM-create host-cwd interpretation. +6. Run the broad native suite; fixture failures that mention missing modules or + entrypoints usually indicate a missing explicit mount or a caller still + sending a host path, not a reason to restore compatibility. + +The main compatibility risk is engine implementation: V8/Pyodide/Wasmtime need +host paths internally. Preserve those host paths as private derived state, but +derive them only from `host_dir` mappings or sidecar-owned shadow files after a +successful kernel VFS lookup.

Current generic request behavior ignores a non-string `configId`, while the generated `AcpSetSessionConfigRequest` carries strings.

Core owns synchronous/resumable host handling; current native/browser tests cover supported and unsupported host requests. | +| `malformed_acp_frames_with_missing_ids_return_invalid_request_errors` | See the explicit unknown-frame follow-up above. Do not preserve the dead codec solely for this assertion. | +| `acp_response_write_failures_put_the_client_into_a_failed_state` | Covered at the current host boundary by core error propagation/abort cleanup and wrapper initial/prompt failure cleanup. The legacy permanent client failure cache no longer exists. | +| `acp_request_method_timeout_overrides_apply_to_initialize_and_prompt` | Covered by engine pending-response timeout assertions (10 s initialize, 30 s new, 600 s prompt) and `acp_request_timeout` (600 s prompt versus 120 s control). Runtime callers no longer supply a client timeout map. | +| `acp_timed_out_session_prompt_sends_cancel_and_ignores_late_response` | Delete the legacy client timeout state. Current resumable timeout is an explicit `AcpAbortPendingRequest` with typed `agent_interaction_timeout` and atomic cleanup, covered by wrapper owner/abort tests. | + +### Inline tests inside `acp_legacy` + +The five `client.rs` inline tests and four `compat.rs` inline tests are duplicate +variants of permission retention/collision/line-limit cases already addressed above. +They run three times because the module is path-included by `acp_integration`, +`acp_session`, and `service`. Delete all nine; retain only the production accumulator +line-limit test. + +## Dependencies and risks + +1. Land the three production-path assertions first or in the same revision: + permission option aliases, protocol-version mismatch cleanup, and boolean config + values. +2. Item 28 is the authority for permission callback timeout/default behavior. Item + 81 must not change its default or recreate client reply routing. +3. Item 8 is the authority for native ACP filesystem/terminal methods. Browser may + explicitly return method-not-found where it has no host callback transport; do + not force artificial native/browser feature parity by copying handlers. +4. Removing `native-sidecar/src/json_rpc.rs` is safe by current search, but include a + final repository-wide search because it is a companion cleanup outside the + tracker row's originally named directory. +5. Deleting `acp_session.rs` removes timing-sensitive Tokio tests. Their timeout + constants must remain covered by sidecar/core tests, not by a new sleep-based + suite. +6. The unknown-frame behavior is a real strictness question, not a reason to keep + the legacy implementation. Track it independently if the main item should remain + a small cleanup revision. + +## Small proposed diff sequence + +1. Extend production-path coverage without deleting anything: add the permission + alias table at `permission_result`, add resumable initialize-version mismatch and + cleanup coverage at `AcpCore::feed_agent_output`, and extend the shared behavior + config test with a boolean `value`. +2. Run the legacy suites and the three new assertions once. This establishes both + the behavior being retired and the replacement coverage in the same revision. +3.

The exact legacy fixture is: + +```json +{"jsonrpc":"2.0","result":{"ok":true}} +``` + +It is complete and syntactically valid JSON, but it is not valid JSON-RPC. It has +`result`, so it is response-shaped, and JSON-RPC 2.0 requires every Response object +to contain `id`. It is not a Notification because notifications require a string +`method`. ACP is bidirectional JSON-RPC over stdio, and stdout is reserved for ACP, +so the sidecar should fail the active interaction immediately with a typed protocol +error instead of treating this as harmless stdout. + +The legacy `-32600` behavior should not be restored. `-32600` is a server Response +to an invalid **Request**. The fixture above is a malformed **Response** from the +adapter while the sidecar is waiting for a correlated response. Sending a Response +to that malformed Response is not a valid correlation, creates uncorrelated wire +traffic, and still does not complete the original interaction. The safe behavior is +a local sidecar error plus the existing adapter-abort cleanup. + +Primary protocol references: + +- [ACP architecture](https://agentclientprotocol.com/get-started/architecture) + describes ACP as bidirectional JSON-RPC over stdin/stdout. +- [JSON-RPC 2.0, Response object](https://www.jsonrpc.org/specification#response_object) + requires `id` and exactly one of `result` or `error`. +- [JSON-RPC 2.0, errors](https://www.jsonrpc.org/specification#error_object) + defines `-32600` as “Invalid Request,” not as a response to an invalid Response. + +## Why this matters + +The current behavior converts a precise protocol violation into a misleading +timeout: + +- initialize can wait 10 seconds; +- `session/new` can wait 30 seconds; +- ordinary methods can wait 120 seconds; +- `session/prompt` can wait 600 seconds. + +All waits remain bounded, so this is not a P0/P1 security-boundary escape. It is a +P2 correctness, availability, and diagnostics issue: a broken adapter can retain a +process/interaction until the deadline and the caller receives “timeout” instead of +“response is missing id.” A malicious adapter could already remain silent for the +same bounded duration, so the change does not close a distinct privilege bypass. + +## Exact production failure chain + +### Shared classification + +`crates/agentos-sidecar-core/src/behavior.rs` owns +`classify_json_rpc_message`. It classifies only by the presence of `id` and a +string-valued `method`: + +```rust +match ( + message.get("id").is_some(), + message.get("method").and_then(Value::as_str).is_some(), +) { + (true, true) => AcpJsonRpcMessageKind::InboundRequest, + (true, false) => AcpJsonRpcMessageKind::Response, + (false, true) => AcpJsonRpcMessageKind::Notification, + (false, false) => AcpJsonRpcMessageKind::Unknown, +} +``` + +The legacy missing-id response reaches `(false, false)` and becomes `Unknown`. +The existing production unit test +`behavior::tests::json_rpc_classifier_prioritizes_inbound_requests_over_notifications` +explicitly locks in that classification for `{"jsonrpc":"2.0"}`. + +### Native production route + +Native does not use the legacy `native-sidecar/src/json_rpc.rs` codec in its real +extension route. That route is: + +1. `crates/agentos-sidecar/src/acp_extension.rs::AcpExtension::run_core_transition` + calls `AcpCore::dispatch_resumable`. +2. `AcpExtension::drive_native_pending` drains the adapter stdout and sends an + `AcpDeliverAgentOutputRequest` back through the core. +3. `crates/agentos-sidecar-core/src/engine.rs` parses complete lines with + `AcpJsonLineAccumulator`, then calls `classify_json_rpc_message` in all four + resumable state machines: + - `advance_create` + - `advance_resume` + - `advance_restart` + - `advance_prompt` +4. Each match currently groups + `AcpJsonRpcMessageKind::Response | AcpJsonRpcMessageKind::Unknown => {}`. +5. The subsequent response-id check cannot match because `id` is absent, so the + interaction is reinserted as pending. Native keeps polling until the applicable + timeout. + +The browser wrapper in `crates/agentos-sidecar-browser/src/lib.rs` also calls +`AcpCore::dispatch_resumable`, so the same shared fix supplies browser parity. + +### Blocking core route + +`crates/agentos-sidecar-core/src/json_rpc.rs::send_json_rpc_exchange` also ignores +`Unknown` alongside unmatched Responses. Production native currently drives the +resumable route, but this blocking route remains exercised by core conformance and +must not retain divergent semantics. + +### Why the legacy test is not production evidence + +`crates/native-sidecar/tests/acp_session.rs::malformed_acp_frames_with_missing_ids_return_invalid_request_errors` +uses `tests/acp_legacy/client.rs`, which in turn uses the dead typed codec from +`crates/native-sidecar/src/json_rpc.rs`. That test-only client responds to every +deserialization failure with the codec's `JsonRpcParseError::to_response()`. +Production does not call that codec or read loop. Item 81 can delete those files; +Item 82 should not preserve them merely to keep the old error shape. + +The codec is still present at the time of this research, but `rg` finds no +production caller outside its own module; only the legacy test modules import it. +“Dead” here means disconnected from the real ACP extension route, not already +deleted from the tree. + +## Exact code map + +Line numbers below describe the Item 80 working tree and are navigation hints; +symbols are the stable edit targets. + +| File / current line context | Symbol | Exact Item 82 edit | +|---|---|---| +| `crates/agentos-sidecar-core/src/behavior.rs:24-47` | `AcpJsonRpcMessageKind`, `classify_json_rpc_message` | Make classification fallible.

Do not broaden Item 82 into checking every `jsonrpc`, `params`, `id`, +and result/error exclusivity rule; the official upstream adapter SDKs own their +wire types, and a copied full parser would recreate the Item 81 problem.

Late + response correlation and tombstones are a separate behavior decision. + +## Cleanup implications and risks + +| Risk / implication | Required handling | +|---|---| +| Classification becomes terminal before the pending state is reinserted. | Preserve the current remove-first `feed_*` wrappers. Their `with_abort_cleanup` call must remain the sole fail-closed process cleanup path. | +| Native abort can itself fail. | Preserve existing `cleanup_failed` aggregation and retry state; do not hide a kill/route-cleanup failure in order to preserve the primary `invalid_state` code. The focused normal-path test should expect `invalid_state`; existing cleanup-failure tests remain authoritative for the exceptional path. | +| Removing `Unknown` also rejects `{}`, `null`, and other complete JSON values previously ignored. | This is intentional because ACP owns adapter stdout. Keep the change limited to classification of complete parsed values; partial lines and whitespace retain `AcpJsonLineAccumulator` behavior. | +| A valid but late Response has an `id` different from the active request. | Continue ignoring it in this item. Treating late ids as fatal requires a separate correlation/tombstone design. | +| Replying with legacy `-32600` could create uncorrelated protocol traffic. | Assert the blocking host records only the original outbound Request. The caller-facing failure is `AcpErrorResponse { code: "invalid_state", ... }`, not another JSON-RPC frame to the adapter. | +| Native E2E tests share heavyweight runtime state. | Add the scenario to `acp_extension_suite` so it runs serially with the existing scenarios, and avoid timing assertions. | +| Item 81 removes the only old test expecting `-32600`. | Record its before result in the tracking document before deletion; Item 82 must not recreate the legacy parser merely to preserve that obsolete expectation. | + +## Proposed diff sequence + +1. On Item 82's parent, add/run the exact missing-id characterization in the + classifier and resumable engine, and record the observed `Unknown`/`Pending` + behavior in `docs/thin-client-migration.md` before changing the expectation. +2. In `behavior.rs`, make `classify_json_rpc_message` return `Result`, remove + `Unknown`, and add the two bounded diagnostics without embedding adapter output. +3. In `json_rpc.rs` and the four `engine.rs` state machines, propagate the + classifier error and leave all valid message routing/correlation logic intact. +4. Rewrite the characterization into after tests: classifier rejection, blocking + no-wire-reply, and resumable abort/cleared-state coverage. +5. Add the malformed-initialize scenario to the serial native + `acp_extension_suite`, using only guest paths plus explicit test mounts, and + assert error taxonomy, no partial ACP session, and successful owner teardown. +6.

You can swap the implementation without changing the agent's behavior.\n- **No credentials in the VM.** The binding executes on the server, so it can access other agents directly without exposing connection details.\n- **Composable.** Chain any number of agents by adding more bindings. Each binding is a self-contained bridge to another agent.\n\n## Recommendations\n\n- Each agent has its own isolated VM and filesystem (they share no filesystem). Pass file contents through the binding input, then use `writeFile` in the binding to land them in the other VM.\n- Use [Workflows](/docs/workflows) to make multi-agent pipelines durable across restarts.","src/content/docs/docs/agent-to-agent.mdx","166030497fa3e2b1","docs/approvals",{"id":20,"data":22,"body":25,"filePath":26,"digest":27,"deferredRender":16},{"title":23,"description":24,"skill":16},"Approvals","Approve or deny agent tool use with human-in-the-loop or auto-approve patterns.","When an agent wants to use a tool (write a file, run a command, etc.), it asks for permission.

The server runs the **sidecar**, the trusted core that hosts every VM: it owns each VM's kernel and brokers every guest syscall the agent makes (filesystem, processes, network, permissions) before carrying it out. Each VM is a fully isolated world, so agents are isolated from one another and from your host.\n\n### Your app (the client)\n\n- **Trusted caller.** Your app drives agentOS. It creates VMs, opens sessions, sends prompts, and reads results back.\n- **Never runs guest code.** The agent and any code it generates run in the VM, not in your app's process.\n- **Available everywhere.** There is a TypeScript client and a Rust client, and the same VM is reachable from a Node script, a browser/React app, or a separate backend.\n- **Owns the configuration.** Everything you send (VM setup, permission policy, resource limits, mounts) is trusted input. See the [Security Model](/docs/security-model) for why your configuration is not an attack surface.\n\n### Your server (the sidecar)\n\n- **The trusted core.** The sidecar is the part of the system that owns everything: the kernel, the virtual filesystem, the process and socket tables, pipes, PTYs, the permission policy, and DNS.\n- **The enforcement point.** Every request the VM makes is serviced here. The sidecar decides what is allowed before carrying it out.\n- **Hosts every VM.** A single sidecar manages many VMs side by side, each with its own kernel, filesystem, and process table, so every agent runs in its own isolated world. A crash or runaway in one VM never affects another.\n\n### The VM\n\n- **A fully virtualized Linux environment.** Each VM has its own filesystem, process table, and network policy. Two VMs share nothing.\n- **The unit of isolation.** Put one tenant or one task per VM to control the blast radius. A crash or runaway in one VM never affects another.\n- **Where guest code lives.** The agent, the shell, npm packages, and any generated code all run inside the VM, behind the kernel's boundary.\n\n## Anatomy of a Linux VM\n\nInside every VM there are two halves. The **kernel** is the trusted core that owns all the resources and rules. The **executor** is where untrusted guest code actually runs. Guest code can only *ask* the kernel for things, it never holds a real capability of its own.\n\n\u003Csvg viewBox=\"0 0 700 360\" role=\"img\" aria-label=\"A VM split into a kernel and an executor.

It runs the guest code and reaches the kernel for everything else.\n\n- **JavaScript Acceleration.** Guest JavaScript runs on a native V8 runtime (the same engine in Chrome and Node.js, with the full JIT compiler) inside an isolate. This is what we call **JavaScript Acceleration**: the guest's JavaScript executes at native speed, not through an interpreter or a translation shim. It is genuinely fast, and it presents normal Node.js semantics. See [JavaScript Runtime](/docs/nodejs-runtime).\n- **WASM alongside it.** The shell (`sh`) and the coreutils behind process execution ship as WebAssembly modules, and you can run your own WASM too. See [POSIX Syscalls](/docs/architecture/posix-syscalls) and the [Compiler Toolchain](/docs/architecture/compiler-toolchain).\n- **Native binaries.** Tools mounted into the VM run inside the same boundary as everything else.\n- **No host fallthrough.** The executor holds no capability of its own. For every file read, process spawn, or socket open, it issues a syscall and blocks for the kernel's reply.\n\n### Processes & shell\n\n\u003Csvg viewBox=\"0 0 480 120\" role=\"img\" aria-label=\"exec, run, and spawn create entries in the kernel-owned virtual process table, with stdio bridged through pipes and PTYs.\" style=\"width:100%;height:auto;max-width:440px;display:block;margin:2.5rem auto;\">\n \u003Cdefs>\n \u003Cmarker id=\"pr-arrow\" viewBox=\"0 0 10 10\" refX=\"9\" refY=\"5\" markerWidth=\"6\" markerHeight=\"6\" orient=\"auto-start-reverse\">\n \u003Cpath d=\"M0,0 L10,5 L0,10 z\" fill=\"#1b1916\" />\n \u003C/marker>\n \u003C/defs>\n \u003Cg font-family=\"var(--sl-font)\" font-size=\"11\" fill=\"#1b1916\">\n \u003Crect x=\"14\" y=\"14\" width=\"92\" height=\"26\" rx=\"6\" fill=\"#ffffff\" stroke=\"#1b1916\" stroke-width=\"1\" />\u003Ctext x=\"60\" y=\"31\" text-anchor=\"middle\">exec() / run()\u003C/text>\n \u003Crect x=\"14\" y=\"78\" width=\"92\" height=\"26\" rx=\"6\" fill=\"#ffffff\" stroke=\"#1b1916\" stroke-width=\"1\" />\u003Ctext x=\"60\" y=\"95\" text-anchor=\"middle\">spawn / shell\u003C/text>\n \u003C/g>\n \u003Cline x1=\"106\" y1=\"27\" x2=\"172\" y2=\"52\" stroke=\"#1b1916\" stroke-width=\"1.3\" marker-end=\"url(#pr-arrow)\" />\n \u003Cline x1=\"106\" y1=\"91\" x2=\"172\" y2=\"66\" stroke=\"#1b1916\" stroke-width=\"1.3\" marker-end=\"url(#pr-arrow)\" />\n \u003Crect x=\"176\" y=\"36\" width=\"138\" height=\"46\" rx=\"10\" fill=\"#faf8f3\" stroke=\"#1b1916\" stroke-width=\"1.4\" />\n \u003Ctext x=\"245\" y=\"56\" text-anchor=\"middle\" font-family=\"var(--sl-font)\" font-size=\"11.5\" font-weight=\"600\" fill=\"#1b1916\">process table\u003C/text>\n \u003Ctext x=\"245\" y=\"71\" text-anchor=\"middle\" font-family=\"var(--sl-font)\" font-size=\"9\" fill=\"#56524a\">virtual · per-VM\u003C/text>\n \u003Cline x1=\"314\" y1=\"59\" x2=\"360\" y2=\"59\" stroke=\"#1b1916\" stroke-width=\"1.3\" marker-end=\"url(#pr-arrow)\" />\n \u003Crect x=\"364\" y=\"40\" width=\"102\" height=\"40\" rx=\"8\" fill=\"#ffffff\" stroke=\"#1b1916\" stroke-width=\"1.2\" />\n \u003Ctext x=\"415\" y=\"64\" text-anchor=\"middle\" font-family=\"var(--sl-font)\" font-size=\"10.5\" fill=\"#1b1916\">pipes & PTYs\u003C/text>\n\u003C/svg>\n\n- **A real process model.** `exec()` and `run()` start fresh guest processes; you can also `spawn` long-running ones and open interactive shells.\n- **Kernel-managed.** Every process lives in the virtual process table, with stdio bridged through kernel-owned pipes and PTYs.\n- **Fresh each run.** Each `exec()` / `run()` starts a brand new guest process, so in-memory state never leaks from one run into the next.\n- See [Processes](/docs/architecture/processes) for the internals.\n\n### Virtual filesystem\n\n\u003Csvg viewBox=\"0 0 480 150\" role=\"img\" aria-label=\"The virtual filesystem layers a writable overlay over a snapshot root, plus mount points that graft host directories, S3, or cloud stores onto guest paths.\" style=\"width:100%;height:auto;max-width:440px;display:block;margin:2.5rem auto;\">\n \u003Cg font-family=\"var(--sl-font)\" font-size=\"11\" fill=\"#1b1916\">\n \u003Crect x=\"60\" y=\"14\" width=\"360\" height=\"30\" rx=\"8\" fill=\"#ffffff\" stroke=\"#1b1916\" stroke-width=\"1.2\" />\u003Ctext x=\"240\" y=\"33\" text-anchor=\"middle\">overlay (guest writes)\u003C/text>\n \u003Crect x=\"60\" y=\"52\" width=\"360\" height=\"30\" rx=\"8\" fill=\"#faf8f3\" stroke=\"#1b1916\" stroke-width=\"1.2\" />\u003Ctext x=\"240\" y=\"71\" text-anchor=\"middle\">root layer (snapshot)\u003C/text>\n \u003C/g>\n \u003Cg font-family=\"var(--sl-font)\" font-size=\"9.5\" fill=\"#1b1916\">\n \u003Crect x=\"60\" y=\"104\" width=\"108\" height=\"32\" rx=\"7\" fill=\"#ffffff\" stroke=\"#1b1916\" stroke-width=\"1\" />\u003Ctext x=\"114\" y=\"124\" text-anchor=\"middle\">host dir mount\u003C/text>\n \u003Crect x=\"186\" y=\"104\" width=\"108\" height=\"32\" rx=\"7\" fill=\"#ffffff\" stroke=\"#1b1916\" stroke-width=\"1\" />\u003Ctext x=\"240\" y=\"124\" text-anchor=\"middle\">S3 mount\u003C/text>\n \u003Crect x=\"312\" y=\"104\" width=\"108\" height=\"32\" rx=\"7\" fill=\"#ffffff\" stroke=\"#1b1916\" stroke-width=\"1\" />\u003Ctext x=\"366\" y=\"124\" text-anchor=\"middle\">cloud store\u003C/text>\n \u003C/g>\n \u003Ctext x=\"240\" y=\"98\" text-anchor=\"middle\" font-family=\"var(--sl-font)\" font-size=\"9\" fill=\"#56524a\">mount points grafted onto guest paths\u003C/text>\n\u003C/svg>\n\n- **Layered engines.** The VFS is a tree of engines: a root layer bootstrapped from a snapshot, an overlay for writes, and mount points that graft other backends onto guest paths.\n- **Host-backed mounts.** A guest path can be backed by a host directory, S3, or a cloud store.

You reach a specific VM by name (`vm.getOrCreate(\"my-agent\")`).\n- **Stateful by default.** Unlike the bare core package, the actor keeps its filesystem and sessions persistent and handles distributed state for you.\n- **The portable runtime.** Actors give you a consistent way to run `agentOS()` on any infrastructure, with persistence, networking, and orchestration built in.\n\n### Cron\n\n- **Recurring work.** Schedule a shell command or an agent session on a cron expression.\n- **Overlap control.** Choose what happens when a run is still going when the next is due (`allow`, `skip`, or `queue`).\n- **Observable.** Stream `cronEvent`s to watch executions. See [Cron Jobs](/docs/cron).\n\n### Workflows\n\n- **Durable multi-step tasks.** A workflow is the actor's `run` handler wrapped in `workflow()`, where each `ctx.step()` is recorded, retried, and resumed independently.\n- **Crash-proof.** If the process dies mid-run, replay skips completed steps and continues where it left off.\n- **Composable.** The output of one step feeds the next: clone a repo, let an agent fix a bug, run the tests. See [Workflow Automation](/docs/workflows).\n\n### Persistence & sleep/wake\n\n- **Sleeps when idle.** After a grace period (15 minutes by default) with no activity, the VM sleeps to free resources.\n- **Wakes on demand.** It wakes automatically when a client connects or a cron job fires.\n- **What survives.** The `/home/agentos` filesystem, session records, transcripts, preview tokens, and cron definitions all persist. In-memory kernel state (running processes, open shells) does not. See [Persistence & Sleep](/docs/persistence).\n\n## Going deeper\n\nThis page is the map.

All numbers are computed from the same data source used by the marketing page. For independent sandbox comparison data, see the [ComputeSDK benchmarks](https://www.computesdk.com/benchmarks/).\n\n## Cold start\n\nTime from requesting an execution to first code running. Measured using the sleep workload (a minimal VM running an idle Node.js process). Sandbox baseline: **E2B**, the fastest mainstream sandbox provider as of March 30, 2026. See [ComputeSDK benchmarks](https://www.computesdk.com/benchmarks/) for independent sandbox comparison data.\n\n| Metric | agentOS | Fastest sandbox (E2B) |\n|---|--:|--:|\n| Cold start p50 | 4.8 ms | 440 ms |\n| Cold start p95 | 5.6 ms | 950 ms |\n| Cold start p99 | 6.1 ms | 3,150 ms |\n\n## Memory per instance\n\nMeasured via staircase benchmarking:\n\n1. **Warmup.** A throwaway VM is created, started, and destroyed before measurement begins. This pays one-time costs (module cache, JIT compilation) that are amortized away in any real deployment where the host process is long-lived.\n2. **Baseline.** GC is forced twice (`--expose-gc`), then RSS is sampled across the entire process tree by reading `/proc/[pid]/statm` for the host process and all descendants. This captures child processes (e.g. V8 isolates running as separate processes) that `process.memoryUsage().rss` would miss.\n3. **Staircase.** VMs are added one at a time. After each VM starts and settles, GC is forced and RSS is sampled again. The delta from the previous sample is the incremental cost of that VM.\n4. **Average.** The per-VM cost is the mean of all step deltas.\n5. **Teardown.** All VMs are disposed and the reclaimed RSS is recorded.\n\nRSS is a process-wide metric that includes thread stacks and OS-mapped pages beyond the VM itself, so the reported figure is an upper bound on the true per-VM cost.\n\nSandbox baseline: **Daytona**, the cheapest mainstream sandbox provider as of March 30, 2026.

All on-demand pricing.\n\n## Reproducing\n\nagentOS benchmarks live in the [agent-os repository](https://github.com/rivet-dev/agentos) under `scripts/benchmarks/`.\n\n### Prerequisites\n\n- Node.js (see `.nvmrc`) and `pnpm`, with dependencies installed: `pnpm install`\n- A Rust toolchain (`cargo`) — the benchmarks build and run the native release sidecar\n- A reasonably **idle machine**: cold-start latency tails are sensitive to background CPU and GC jitter\n\n### Run everything\n\nFrom the repository root:\n\n```sh\n./scripts/benchmarks/run-benchmarks.sh\n```\n\nThe script builds the TypeScript packages and an **optimized (release) sidecar**, points the SDK at it via `AGENT_OS_SIDECAR_BIN`, and writes one JSON result per benchmark to `scripts/benchmarks/results/`:\n\n| Result file | Feeds marketing input |\n|---|---|\n| `coldstart-sleep.json` | `COLDSTART_P50/P95/P99_MS` |\n| `memory-sleep.json` | `MEMORY_SHELL_MB` (`result.avgPerVmRssBytes / 1024²`) |\n| `memory-pi-session.json` | `MEMORY_AGENT_MB` (`result.avgPerVmRssBytes / 1024²`) |\n\nCopy those numbers into `website/src/data/bench.ts`; every figure and multiplier on this page recomputes from them.\n\n### Run a single benchmark\n\nEach benchmark is a standalone `tsx` entrypoint. Build first (`pnpm build` and `cargo build --release -p agent-os-sidecar`), then:\n\n```sh\nexport AGENT_OS_SIDECAR_BIN=\"$PWD/target/release/agent-os-sidecar\"\n\n# Cold start (sleep workload)\npnpm exec tsx scripts/benchmarks/coldstart.bench.ts --workload=sleep --iterations=2000\n\n# Memory — simple shell command\npnpm exec tsx --expose-gc scripts/benchmarks/memory.bench.ts --workload=sleep --count=20\n\n# Memory — full coding agent\npnpm exec tsx --expose-gc scripts/benchmarks/memory.bench.ts --workload=pi-session --count=10\n```\n\nJSON goes to stdout; a human-readable table and progress go to stderr.\n\n### Sample sizes\n\nPercentiles are nearest-rank: `sorted[ceil(p/100 · n) − 1]`. With too few samples the tail is meaningless — at `n = 30`, **p99 is literally the single slowest run** and p95 is the second slowest. Use enough iterations that the reported percentile is averaged over real tail samples, not one outlier:\n\n| Statistic | Minimum iterations |\n|---|--:|\n| p50 (median) | ~30 |\n| p95 | ~200 |\n| p99 | ~1,000 |\n\n`run-benchmarks.sh` uses `--iterations=2000` for cold start so p95/p99 are trustworthy. Memory per VM is a mean of per-VM step deltas with low variance, so `--count=20` (shell) / `--count=10` (agent) is sufficient.\n\n> The `pi-session` memory workload needs a working in-VM agent runtime (the Pi adapter process must launch inside the VM). On builds where the agent runtime is unavailable it will fail its process check rather than report a number.\n\n### Methodology\n\nEvery benchmark **creates the sidecar once up front** (`AgentOs.createSidecar()`) and leases all VMs from it. VMs are **incremental tenants of one shared sidecar process** — not one process each — so the figures measure the marginal cost of a VM, not a fresh process. (`AgentOs.create()` with no `sidecar` option already uses the shared `default`-pool sidecar, so this is the default everywhere, including RivetKit actors.)\n\nBefore any measured iteration, each benchmark does a **cold run** — a throwaway VM that is created, started, and (for cold start) snapshotted. This pays the one-time process spawn + bootstrap so the recorded numbers reflect the warm, steady-state incremental per-VM cost, never the first VM. The release sidecar is required: a debug build is several times slower and inflates the numbers.","src/content/docs/docs/benchmarks.mdx","8b389f84726bb5c2","docs/bindings",{"id":52,"data":54,"body":57,"filePath":58,"digest":59,"deferredRender":16},{"title":55,"description":56,"skill":16},"Bindings","Expose custom host functions to agents as CLI commands inside the VM.","Expose your host JavaScript functions (defined with Zod input schemas) to agents as auto-generated CLI commands installed at `/usr/local/bin/agentos-{name}` inside the VM, injected into the agent's [system prompt](/docs/system-prompt) and callable inside scripts for code-mode token savings.\n\n## Getting started\n\nDefine a bindings group with Zod input schemas and pass it to `agentOS()`. Each binding becomes a CLI command inside the VM.\n\n\u003CCodeGroup>\n\u003CCodeSnippet file=\"examples/bindings/server.ts\" />\n\n\u003CCodeSnippet file=\"examples/bindings/client.ts\" />\n\u003C/CodeGroup>\n\nEach binding can set an explicit `timeout` (in milliseconds) for long-running work.

Required fields are enforced at validation time. Use `.describe()` on Zod fields to generate useful `--help` output.\n\n### What the agent sees\n\nWhen bindings are registered, CLI shims are installed at `/usr/local/bin/agentos-{name}` inside the VM and the binding list is injected into the agent's [system prompt](/docs/system-prompt), so keep binding descriptions concise to save tokens.\n\nThe agent interacts with bindings as shell commands:\n\nThe listing subcommand is still named `list-tools` for CLI compatibility.\n\n```bash\n# List all available bindings groups\nagentos list-tools\n\n# List bindings in a specific group\nagentos list-tools weather\n\n# Get help for a binding\nagentos-weather forecast --help\n\n# Call a binding with flags\nagentos-weather forecast --city Paris --days 3\n\n# Call a binding with inline JSON\nagentos-weather forecast --json '{\"city\":\"Paris\",\"days\":3}'\n\n# Call a binding with JSON from a file\nagentos-weather forecast --json-file /tmp/input.json\n```\n\nOn success, the binding exits `0` and writes a JSON envelope to stdout:\n\n```json\n{\"ok\":true,\"result\":{\"temperature\":22,\"condition\":\"sunny\"}}\n```\n\nOn failure (validation or execution error), the binding exits non-zero and writes the error message to stderr:\n\n```text\nMissing required flag: --city\n```\n\n## Bindings vs MCP servers\n\nagentOS supports two ways to give agents access to external functionality: **bindings** and **MCP servers**. Both work, but they have different tradeoffs.\n\n| | Bindings | MCP Servers |\n|---|---|---|\n| **How it works** | Call JavaScript functions on the host directly | Connect to a standard MCP server |\n| **Authentication** | None required. Direct binding to the agent's OS. | Requires custom auth configuration per server |\n| **Code mode** | Built-in. Bindings are exposed as CLI commands, so agents can call them inside scripts for up to 80% token reduction. | Requires extra work to make code mode work out of the box |\n| **Latency** | Near-zero. Bound directly to the host process. | Extra network hop to reach the MCP server |\n| **Setup** | Define bindings in your actor code with Zod schemas | Configure any standard MCP server |\n\nUse bindings when you want to expose your own JavaScript functions to agents. Use MCP servers when you want to connect to existing third-party services. See [Sessions](/docs/sessions#createsession-options) for MCP server configuration.\n\n## Security\n\nBinding calls from the agent securely invoke your `execute()` functions on the host. Your functions run with full access to the host environment, so you can call databases, APIs, and services directly without proxying credentials into the VM.

By default all VMs are tenants of a single, process-global sidecar (the `default` pool), so each additional VM only adds its marginal cost — a V8 isolate plus its kernel state — instead of a whole OS process. This is what keeps per-VM memory in the tens of MB and warm VM creation in the single-digit milliseconds (see [Benchmarks](/docs/benchmarks)).\n\nThis is automatic — `agentOS()` and `AgentOs.create()` use the shared default sidecar with no configuration, and the same applies to Rivet Actors (each actor's VM is a tenant of the shared process). Disposing a VM tears down only that VM; the shared sidecar process is reused across VMs and stays alive for the lifetime of the host process.\n\nFor advanced cases the core package exposes explicit sidecar handles so you can isolate a group of VMs in their own process:\n\n\u003CCodeSnippet file=\"examples/core/advanced.ts\" title=\"advanced.ts\" />\n\n## Filesystem\n\n\u003CCodeSnippet file=\"examples/core/client.ts\" region=\"filesystem\" title=\"client.ts\" />\n\n## Processes\n\nLong-running process output is delivered over the live `processOutput` / `processExit` events on a connection rather than per-pid callbacks:\n\n\u003CCodeSnippet file=\"examples/core/client.ts\" region=\"processes\" title=\"client.ts\" />\n\n## Agent sessions\n\n`createSession` returns a session record.

That changes the cost model for running coding-agent VMs from \"pay a provider per sandbox-second\" to \"pay for the compute you provision, then pack as much work onto it as it can hold.\" This page explains where the savings come from and how to reason about them honestly. It does not publish a single magic multiplier, because the real number depends on your workload, your hardware, and how you share VMs.\n\n\u003CNote>For measured latency (cold start, warm execution, and reuse fast paths), see [Benchmarks](/docs/benchmarks). This page is about cost structure, not raw performance.\u003C/Note>\n\n## Where the savings come from\n\nTwo structural differences drive the cost gap versus per-second sandbox providers:\n\n- **You run on your own hardware**: you choose the cloud, instance type, architecture, and region. A small commodity instance (for example an ARM VM from a budget host) costs a flat hourly or monthly rate that is typically far below what per-sandbox-second billing adds up to once you have steady agent traffic. You also avoid egress fees and vendor lock-in.\n- **You decide the isolation granularity**: sandbox providers bill a full container or microVM per execution, usually with a minimum memory reservation that you pay for even when your code uses a fraction of it. With agentOS you own the VM lifecycle: you can dedicate a VM per tenant or per task for maximum isolation, or amortize setup by reusing one VM across many runs.\n\n## The isolation model matters for cost\n\nEach `AgentOs.create()` boots a fully virtualized VM, and each `exec()` / `run()` inside it is a fresh guest process. That gives you a dial between isolation and density:\n\n- **One VM per task or tenant (strongest isolation)**: create a VM, run the work, and dispose it, or give each tenant its own VM. Each VM is its own crash and resource domain, with the highest per-VM overhead. Best when load is untrusted or bursty.\n- **A shared VM for trusted work**: reuse one VM across many runs to amortize the VM boot cost. Each `exec()` / `run()` still executes in a fresh guest process, so in-memory state does not leak between runs, but the VM and filesystem are shared. Good for trusted, sequential work.\n\nThe denser you can safely pack agent work onto an instance, the lower your effective cost per execution. See [Resource Limits](/docs/resource-limits) for the per-VM caps that govern how densely you can pack, and [Processes & Shell](/docs/processes) for how guest processes run inside a VM.\n\n## How to estimate your own cost\n\nBecause agentOS runs on hardware you provision, the honest way to compare is to plug in your own numbers:\n\n1. **Pick your hardware and its rate**: take the hourly or monthly price of the instance you would run on, and divide down to a per-second instance cost.\n2. **Estimate how many concurrent VMs fit**: measure per-VM memory overhead on your target hardware under your isolation strategy, then divide your usable RAM by that figure. Leave headroom (the measurement and any orchestration layer will not bin-pack perfectly).\n3. **Divide instance cost by concurrent VMs**: that gives a cost-per-VM-second you can compare against a provider's per-sandbox-second rate.\n\n\u003CTip>Measure on the hardware and isolation strategy you will actually deploy. Per-VM overhead depends on whether you create a fresh VM per task or reuse one across runs, and on the work the agent does, so a number measured on one machine will not transfer cleanly to another.\u003C/Tip>\n\n## Comparing against sandbox providers\n\nWhen you do compare against a per-second sandbox provider, hold the methodology honest:\n\n- **Sandbox cost** is the provider's minimum allocatable memory times their per-GiB-second rate (plus any egress and platform fees). The minimum reservation is the floor you pay even for tiny workloads.\n- **agentOS cost** is your instance cost per second divided by the number of VMs you can keep live on it, with realistic headroom for bin-packing inefficiency.\n\nThe advantage is largest for **many small, short executions**, where a per-sandbox minimum reservation dominates and your own hardware lets you pack densely. It narrows for **heavyweight, long-lived workloads** (for example dev servers that need hundreds of megabytes regardless), where the win shifts from density to hardware choice: you still avoid per-second metering, egress fees, and lock-in, but the raw memory-density advantage is smaller.\n\n| Workload | Primary cost advantage |\n| --- | --- |\n| Many small, short executions | Density: pack many VMs per instance, no per-sandbox minimum |\n| Heavyweight, long-lived workloads | Hardware choice, flat instance pricing, no egress or lock-in |\n| High concurrency | Reuse a VM across runs to amortize VM boot cost |\n\n\u003CWarning>Be careful generalizing cost ratios from a single benchmark. Provider pricing, instance pricing, and exchange rates change over time, and per-VM overhead varies by workload and isolation strategy. Re-measure on your own hardware before quoting a number.\u003C/Warning>\n\nWhen you do need a full Linux sandbox for heavier agent workloads, see [agentOS vs Sandbox](/docs/versus-sandbox) for how the two models combine.","src/content/docs/docs/cost-evaluation.mdx","d061affd8af70768","docs/crash-course",{"id":76,"data":78,"body":81,"filePath":82,"digest":83,"deferredRender":16},{"title":79,"description":80,"skill":16},"Crash Course","Run coding agents inside isolated VMs with full filesystem, process, and network control.","\u003CNote>\nagentOS is in preview and the API is subject to change.

The agent then reads and writes the sandbox's files through the same `fs` APIs while the sandbox handles execution. See [Sandbox Mounting](/docs/sandbox) for setup.\n\n## Default layout\n\nWith no `mounts` configured, every VM boots an Alpine-based root filesystem with the standard POSIX directories:\n\n- `/home/agentos`: the agent's home directory (`$HOME`) and default working directory (`pwd`) when spawned, where it reads and writes (mounts land under it, e.g. `/home/agentos/data`).\n- `/bin`, `/sbin`, `/usr`: installed commands (common POSIX utilities by default, plus any [software](/docs/software) you add).\n- `/etc`, `/lib`, `/opt`, `/root`, `/run`, `/srv`, `/tmp`, `/var`, `/mnt`: standard system paths.\n\nIt is backed by the VM's own filesystem and persisted across sleep/wake.

Every guest VM executes its JavaScript inside this runtime, fully sandboxed from the host.\n\n## JavaScript Acceleration\n\n- **JavaScript is unusually slow as WebAssembly**: unlike most software, JavaScript pays a heavy penalty when compiled to WebAssembly, because so much engineering has gone into JIT-compiling JavaScript directly in V8.\n- **Native V8, full JIT**: agentOS therefore runs guest JavaScript on the native V8 engine with its full JIT compiler, not through a WASM translation layer. We call this **JavaScript Acceleration**.\n- **Native-speed execution**: guest JavaScript runs at native speed while staying inside the isolation boundary, with normal Node.js semantics.\n\n## Comparison to Node.js efficiency\n\n- **Isolate model, not processes**: agentOS runs each agent inside a V8 isolate rather than spawning a full Node.js process per agent.\n- **Low memory overhead**: an isolate carries far less per-agent memory overhead than a full Node.js process, so many agents fit in the footprint that a process-per-agent model would spend on a handful.\n- **Benchmarks**: see the Secure Exec [benchmarks](https://secureexec.dev/docs/benchmarks) for cold start, warm execution, and reuse measurements.\n\n## Node.js compatibility\n\nGuest code runs as Node.js (reporting `process.version` as `v22.0.0`), but it never touches the host runtime. Every `node:` builtin resolves to a kernel-backed bridge or an in-isolate polyfill, never the real host module. For the full builtin matrix (`fs`, `net`, `http`, `crypto`, undici-backed `fetch`, and more), see the Secure Exec [Node.js Compatibility](https://secureexec.dev/docs/nodejs-compatibility) reference.\n\n### npm packages\n\nBy default the VM has no npm packages installed. Mount a host `node_modules` directory to give guest code access to real packages: the `nodeModulesMount` helper projects it read-only at `/root/node_modules`, and the in-kernel resolver walks it exactly like Node.js does, with no bundling or patching.\n\n\u003CCodeSnippet file=\"examples/js-runtime/node-modules-mount.ts\" />\n\nResolution matches naive Node.js over the mounted tree: the ancestor `node_modules` walk, `package.json` `exports`/`imports` and conditions, and `realpath`/symlink following (so pnpm and yarn layouts resolve too). Both ESM `import` and CommonJS `require` work.

The [sandbox mounting](/docs/sandbox) extension mounts the sandbox as a filesystem and lets you execute commands on it, like mounting a hard drive on your own machine. Files written in the VM are available in the sandbox and vice versa.\n\nSee [agentOS vs Sandbox](/docs/versus-sandbox) for a detailed comparison.\n\n## Limitations\n\n### Software registry\n\nagentOS uses its own [software registry](/registry) of popular tools cross-compiled for the runtime. You cannot download and install arbitrary binaries (for example via `curl` or `apt`), and standard Linux package managers (`apt`, `yum`) are not available since agentOS runs a streamlined Linux environment rather than a full distribution. Native binaries that are not yet available in the registry (such as Go, Rust, or C++ toolchains) require a full [sandbox](/docs/sandbox).\n\nSee [Software](/docs/software) for how to install and configure available packages.\n\n### Lightweight Linux kernel\n\nagentOS provides a POSIX-compliant virtual Linux kernel with full filesystem operations, networking, and process management.

Runaway or malicious guest code can exhaust its own VM, but it can never starve the host or any sibling VM.\n\n- **Bounded by default**: each VM ships with conservative caps. Unset fields fall back to built-in defaults that match the runtime's historical constants.\n- **Per-VM**: every VM gets its own budget. Limits are not shared across VMs.\n- **Enforced by the kernel**: a guest that exceeds a cap fails inside the VM (out-of-memory, `EMFILE`, `EAGAIN`, etc.). The host is never affected.\n- **Operator-raisable**: the operator (the trusted process that creates the VM) may raise any cap for trusted workloads. Guest code can never raise its own caps.\n\n## Setting limits\n\nSet caps on the `limits` object in the `agentOS` config. Limits are grouped by subsystem (`resources` and more). Omitted limits keep their secure default.\n\n\u003CCodeSnippet file=\"examples/resource-limits/server.ts\" />\n\n## Available caps\n\n| Limit | Controls | Notes |\n|---|---|---|\n| `resources.maxProcesses` | Concurrent processes in the VM process table | Caps fork bombs and runaway spawning. New spawns fail with `EAGAIN`. |\n| `resources.maxOpenFds` | Open file descriptors | Exhausting the table fails with `EMFILE` / `ENFILE`. |\n| `resources.maxSockets` | Open sockets in the socket table | Bounds concurrent connections; excess `connect`/`accept` fail. |\n| `resources.maxFilesystemBytes` | Total bytes stored in the virtual filesystem | Bounds VFS storage; writes past the budget fail with a no-space error. |\n| `resources.maxWasmStackBytes` | Maximum WASM call-stack size, in bytes | Deep recursion fails with a stack overflow instead of crashing the VM. |\n\n## Behavior at the limit\n\n- **WASM stack**: deep recursion throws a stack-overflow error in the guest, never a host crash.\n- **Filesystem bytes**: writing past the VFS budget fails with a no-space error to the guest.\n- **Counts (fds / processes / sockets)**: hitting a table cap returns the standard POSIX errno (`EMFILE`, `EAGAIN`, etc.), exactly as a real Linux kernel would under `ulimit`.\n\n## Warnings & observability\n\nLimits are observable, not just enforced. Every bound — resource caps and the\ninternal bounded queues alike — is tracked in a central limit registry that:\n\n- **Warns before the limit is hit.** As usage crosses ~80% of a cap, the runtime\n emits a structured warning (once per crossing, re-armed only after it recovers),\n so a slow consumer or a runaway guest is visible *before* it fails.\n- **Applies backpressure instead of failing catastrophically.** The internal\n queues between the guest, the runtime, and the host block their producer when\n full rather than dropping data or tearing down the session — so a transient\n burst degrades to \"slower\", not \"broken\".\n- **Surfaces through logs.** secure-exec logs to stderr (stdout is the wire\n protocol); set `SECURE_EXEC_LOG=warn` (the default) to see near-limit warnings\n or `SECURE_EXEC_LOG=debug` for live per-limit usage snapshots.\n\nSee [Limits & Observability](/docs/architecture/limits-and-observability) for the\nfull architecture.","src/content/docs/docs/resource-limits.mdx","14df899437cdbdba","docs/sandbox",{"id":226,"data":228,"body":231,"filePath":232,"digest":233,"deferredRender":16},{"title":229,"description":230,"skill":16},"Sandbox Mounting","Extend agentOS with full sandboxes for heavy workloads like browsers, desktop automation, and compilation.","For heavy workloads like browsers, desktop automation, and compilation, pair agentOS with a full sandbox on demand. Its filesystem mounts into the VM as a native directory, and its process management is exposed as [bindings](/docs/bindings), all provider-agnostic through [Sandbox Agent](https://sandboxagent.dev).\n\n## Why use agentOS with a sandbox?\n\nagentOS is an alternative to sandboxes that covers most use cases, but some workloads need a full sandbox for special kinds of software (browsers, desktop automation, heavy compilation). Sandbox mounting lets you lazily start a sandbox on demand, only when it is needed, and project it into the VM. The hybrid model means one agent session can handle both lightweight coding tasks and heavy system operations, using the right tool for each.\n\nSee [agentOS vs Sandbox](/docs/versus-sandbox) for a detailed comparison.\n\n## When to use a sandbox\n\n- **Native binaries** not yet supported in the agentOS runtime.\n- **Browsers and desktop automation**: Playwright, Puppeteer, Selenium, or anything that needs a display server.\n- **Heavy compilation**: Large builds or native toolchains that require a full Linux environment.\n- **GUI applications**: Desktop apps, VNC sessions, or any workload that needs a graphical environment.\n- **Node.js packages with native extensions** (e.g. `sharp`, `bcrypt`, `better-sqlite3`) that require a full build toolchain.\n\nStart with the default agentOS VM for all workloads, and only spin up a sandbox when a task genuinely requires one. Sandboxes are billed per second of uptime, so start them on demand and tear them down when the task is done.\n\n## Getting started\n\nThe sandbox integration ships as the `@rivet-dev/agentos-sandbox` package. It works through two mechanisms:\n\n- **Filesystem mount**: Projects the sandbox into the VM as a native directory, like mounting a hard drive on your own machine. Read and write files through the mount directly.\n- **Bindings**: Exposes sandbox process management as [bindings](/docs/bindings). Execute commands on the sandbox from within the VM.\n\nBoth are powered by [Sandbox Agent](https://sandboxagent.dev), and you can swap providers without changing agent code. Install both packages:\n\n```bash\nnpm install @rivet-dev/agentos-sandbox sandbox-agent\n```\n\n`createSandboxFs` and `createSandboxBindings` come from `@rivet-dev/agentos-sandbox`. `SandboxAgent` and the provider helpers (such as `docker`) come from the `sandbox-agent` package.\n\n\u003CCodeSnippet file=\"examples/sandbox/server.ts\" />\n\n## Calling the mounted bindings\n\nOnce the sandbox is mounted, write code through the filesystem and run it inside the sandbox. The sandbox bindings are exposed inside the VM as a CLI command, so you call it through the same `exec`/`spawn` surface as any other command.\n\n\u003CCodeSnippet file=\"examples/sandbox/client.ts\" />\n\n## Bindings reference\n\nThe bindings expose these commands inside the VM:\n\n```bash\n# Run a command synchronously\nagentos-sandbox run-command --command \"npm install\" --cwd \"/app\"\n\n# Start a background process\nagentos-sandbox create-process --command \"npm\" --args \"run\" --args \"dev\"\n\n# List running processes\nagentos-sandbox list-processes\n\n# Get process output\nagentos-sandbox get-process-logs --id \"proc_abc123\"\n\n# Stop or kill a process\nagentos-sandbox stop-process --id \"proc_abc123\"\nagentos-sandbox kill-process --id \"proc_abc123\"\n\n# Send input to an interactive process\nagentos-sandbox send-input --id \"proc_abc123\" --data \"yes\"\n```\n\n## Sandbox providers\n\nThe extension works with any [Sandbox Agent](https://sandboxagent.dev) provider. See the [Sandbox Agent documentation](https://sandboxagent.dev) for available providers and setup instructions.","src/content/docs/docs/sandbox.mdx","cd14b3cdc9717d6b","docs/security-model",{"id":234,"data":236,"body":239,"filePath":240,"digest":241,"deferredRender":16},{"title":237,"description":238,"skill":16},"Security Model","Trust boundaries, isolation guarantees, and the agentOS threat model.","\u003CWarning>\nagentOS is in beta and still undergoing security review. The security model described here is subject to change.\n\u003C/Warning>\n\nagentOS is a sandbox: it runs **untrusted code safely on behalf of a trusted caller**. Every actor boots its own fully virtualized VM with a virtual filesystem, process table, socket table, pipes, PTYs, a permission policy, and managed language runtimes. Guest JavaScript executes in a V8 isolate, and every guest syscall is serviced by the kernel rather than the host. There are no host escapes: guest code cannot spawn a real host process, touch the real host filesystem, or open a real host network socket.\n\n## Deny by default\n\nNo syscalls are bound to the system by default. Everything is denied until explicitly opted in.\n\n- **Network access** is denied until you opt in with a `network` permission.\n- **Filesystem mounts** expose nothing of the host until you configure them.\n- **Process spawning** runs only kernel-managed guest processes, never host processes.\n- **All other host capabilities** must be configured by the host before the VM can use them.\n\nOther in-VM scopes (the virtual filesystem, child processes, process info, env) are enabled so that normal programs run, but they are mediated entirely by the kernel and never touch the host.\n\n## Trust model: three components\n\nBefore judging whether something is a security bug, decide which side of the boundary it is on. agentOS has three components with very different trust levels.\n\n\u003Csvg

application code, container, or serverless function.\n\n- The client process and **every value it sends** are trusted: VM config, mount descriptors and their plugin configs (host directory paths, S3 endpoints and credentials, etc.), the permission policy, network allowlist, resource limits, env, and DNS overrides.\n- **Configuration is not an attack surface.** A defect that requires the client to supply a malicious config, endpoint, credential, or policy is not a sandbox vulnerability: the client is configuring its own VM and already controls the host.\n- The **one** thing from the client that is *not* trusted is the **code/payload** it asks to run, because that runs in the executor. How code reached the executor never makes it trusted.\n\nYou are responsible for hardening this side. See [What you are responsible for](#what-you-are-responsible-for).\n\n### Sidecar / kernel (trusted, the enforcement point)\n\nThe trusted computing base. It brokers client requests and owns the kernel, VFS, mount/plugin registry, socket table, and permission policy. It is responsible for enforcing the boundary against the executor.\n\n### Executor (untrusted, the adversary)\n\nV8 isolates or WASM running guest JS/Python/WASM plus any third-party, npm, or agent-generated code.\n\n- Assume everything here is **actively hostile**.\n- The executor reaches the outside world only through kernel-owned VFS, process, socket, pipe, PTY, permission, and DNS paths.\n\n## The security boundary\n\n**The security boundary is sidecar ↔ executor.** The runtime must stop guest code in the executor from:\n\n- Escaping the kernel boundary (the real host filesystem, network, process table, or memory).\n- Bypassing the **applied** permission policy, allowlist, or limits.\n- Exhausting host resources beyond configured bounds.\n- Reading another VM's state.\n\nTwo corollaries that are easy to get wrong:\n\n- **Trusted policy, untrusted subject.** The permission policy and limits are trusted input, but the guest executor is the subject they bind. \"Guest bypasses an applied permission, egress rule, or resource cap\" is in-scope and serious. Trusted = who sets the rule; untrusted = who is bound by it.\n- **Trusted mount, untrusted traffic.** A host-backed mount (host directory, S3, etc.) comes from trusted config, so its existence, target, and credentials are not attack surface. But the guest drives I/O through it, so confining those guest operations to the mount root (symlink, `..`, TOCTOU, and path-aliasing escapes) is in-scope.\n\n### In scope vs out of scope\n\n| In scope (sandbox escape) | Out of scope (not a sandbox bug) |\n| --- | --- |\n| Guest reaches the real host fs / net / process / memory | Client supplies a malicious config / endpoint / credential / policy |\n| Guest bypasses an applied permission, egress rule, or limit | Hardening that only guards trusted client-provided configuration |\n| Guest exhausts host resources past configured bounds | Wire-level authn/authz between mutually distrusting clients |\n| Guest reads another VM's state | VM-to-VM access via forged connection IDs (single-client transport) |\n| Guest escapes a host-backed mount root (symlink / `..` / TOCTOU) | The existence or target of a configured mount |\n\n**Transport scope.** The wire protocol is same-version lockstep and single-client over stdio (one trusted client per sidecar process). There is no second, mutually-distrusting client, so wire-level authn/authz between clients and VM-to-VM access via forged connection IDs are out of scope until a multi-client transport exists.\n\n## VM isolation\n\nEach agentOS actor runs in its own isolated VM.\n\n- **Sandboxed execution.** All agent code runs inside a V8 isolate with WebAssembly. No code escapes the isolate boundary.\n- **Virtual filesystem.** The VM has its own in-memory filesystem. Guest reads and writes never reach the real host filesystem. Agents cannot access host files unless explicitly mounted.\n- **Virtual network.** The VM has no direct access to the host network. Outbound requests are proxied through the host with configurable controls.\n- **Process isolation.** No host process is visible or accessible from inside the VM.\n- **Per-actor containment.** Each actor is its own VM. Two actors share no filesystem, globals, module state, memory, or crash fate. The sidecar process that hosts those VMs may be shared by default as a performance optimization, but isolation is enforced at the VM level, not the host-process level.\n\n### Kernel-owned syscall paths\n\nEvery guest syscall is mediated by the kernel and checked against the runtime's permission policy. Concretely, the kernel mediates:\n\n- **Filesystem.** A virtual, in-memory filesystem. Guest reads and writes never reach the real host filesystem. Host data enters the VM only through the `files`, `mounts`, or `nodeModules` you configure explicitly. See [Filesystem](/docs/filesystem).\n- **Processes.** `node:child_process` spawns kernel-managed guest processes, never real host processes. Children can only run the commands the VM mounts (WASM-backed `sh` and coreutils, V8-backed `node`). See [Processes](/docs/processes).\n- **Network.** Guest `fetch()`, `node:http`, and raw sockets all flow through the kernel socket table. Guest `fetch()` runs through undici inside the isolate and then through the kernel socket table; it never opens a real host socket. See [Networking](/docs/networking).\n- **DNS, pipes, and PTYs** are likewise kernel-owned: no guest path reaches the host directly.\n- **Bindings.** Registered [bindings](/docs/bindings) are the only sanctioned way to hand the guest a named host capability. The guest invokes a binding by name with JSON input, the call round-trips to the host handler, and only the handler's return value comes back. The guest never receives the underlying host access.\n\n## What enters the VM\n\nThe host filesystem is never exposed to the guest by default. Host data crosses the boundary only through options you configure:\n\n- **`files`** seed bytes into the virtual filesystem. The bytes are copied in; the host path is never exposed.\n- **`mounts`** project a host directory at a guest path, Docker-style. The guest sees only the mounted subtree, read through the VFS lazily, never the wider host filesystem. Mounts are read-only unless you opt out.\n- **`nodeModules`** project a host `node_modules` directory (read-only, lazily) at a guest path so guest `import`/`require` resolves real installed packages.\n\nIn every case the guest sees only the subtree you mount, and writes to read-only mounts are rejected.\n\n## Permissions\n\nPermissions are the capability gate at the boundary. They merge over a secure default that denies the network and enables the filesystem, child processes, process info, and env. Because the merge is partial, you name only the scope you change.\n\n```ts\n// Grant network egress; everything else keeps the secure defaults.\npermissions: { network: \"allow\" }\n```\n\nA scope can be `\"allow\"`, `\"deny\"`, or a `{ default, rules }` policy that matches request patterns. Guest servers are reachable only over loopback inside the VM unless you exempt a port explicitly. See [Permissions](/docs/permissions) and [Networking](/docs/networking) for the full policy shape.\n\n## Resource and timing limits\n\nThe VM bounds guest execution so runaway or hostile code cannot hang or exhaust the host:\n\n- **Timeouts and cancellation** kill or cancel a run from the outside.\n- **Memory, CPU-time, and payload limits** are enforced by the VM.\n- **Timing-side-channel mitigation.** In the default mode, high-resolution clocks (`Date.now()`, `performance.now()`, `process.hrtime()`) are frozen within a run and `SharedArrayBuffer` is removed, to blunt timing side channels of the kind used in Spectre-style attacks.\n\nSee [Security & Auth](/docs/security-model) for resource limits, network control, and authentication setup.\n\n## What agentOS guarantees\n\n- Agent code cannot read or write host files outside configured mounts.\n- Agent code cannot make network requests except through the host proxy.\n- Agent code cannot access host environment variables or secrets.\n- Each actor's filesystem, sessions, and state are isolated from other actors.\n- Resource limits (CPU, memory) are enforced at the VM level.\n- A crash, resource exhaustion, or escape attempt is contained to a single VM; other VMs keep running, even when they share a sidecar process.\n\n## What you are responsible for\n\nThe boundary protects the host from the guest. It does **not** harden your host process against everything else. The VM alone is not enough without a hardened host, and a hardened host alone does not protect against code that runs with full host access inside your own process.\n\n- Hardening the host process and deployment environment. For internet-facing workloads that take untrusted input, run your host inside an already-hardened environment (for example AWS Lambda, Google Cloud Run, or a similar sandboxed platform).\n- Validating authentication tokens in `onBeforeConnect`.\n- Scoping [permissions](/docs/permissions) appropriately for your use case.\n- Managing API keys and secrets on the host side (use the [LLM gateway](/docs/llm-gateway) to avoid passing keys into the VM).\n- Configuring [resource limits and network controls](/docs/security-model) to match your threat model.\n- Choosing your blast radius: prefer a fresh VM per untrusted or high-risk task so an escape attempt cannot outlive a single VM.\n\n\u003CWarning>The boundary contains guest code, but you still own the host.

For the agent-author view (how to opt in and the rules your SDK must follow), see [Software Definition → SDK snapshotting & snapshot-safety](/docs/custom-software/definition). For how sessions work in general, see [Agent Sessions](/docs/architecture/agent-sessions).\n\n## The problem: per-session SDK re-evaluation\n\nWhen a session starts, its agent adapter runs inside a fresh [V8 isolate](/docs/architecture/agent-sessions) and imports the agent SDK (for Pi, `@mariozechner/pi-coding-agent`). Importing a real-world SDK means resolving, loading, compiling, and **evaluating** a large module graph — hundreds of modules running their top-level initialization. That evaluation dominates session-creation latency, and because every session gets a fresh isolate, it is paid *again on every `createSession`*.\n\nThe work is identical every time: the same modules, evaluated to the same post-init heap, only to be thrown away when the session ends. Snapshotting captures that post-init heap once and stamps it into every new isolate.\n\n## How V8 heap snapshots work here\n\nagentOS already boots every guest isolate from a **V8 startup snapshot** of the runtime bridge (the polyfill layer that provides `fetch`, node builtins, the kernel-backed module loader, etc.). A startup snapshot is a serialized image of a V8 heap *after* some code has run; restoring it into a fresh isolate reproduces that heap by deserialization rather than re-execution, and each restore produces an independent context.\n\nAgent SDK snapshotting extends that same mechanism: it evaluates the agent SDK **into the same snapshot context, right after the bridge**, so the captured image contains the bridge *and* the fully-initialized SDK. Restoring it gives a fresh isolate where the SDK is already present — no import, no evaluation.\n\n## Where it sits in the component model\n\nThe [three components](/docs/architecture#the-big-picture) are unchanged. Snapshotting only changes *how* the executor's isolate is seeded:\n\n- **Client.** Builds the SDK bundle at package-build time and passes it to the sidecar as trusted VM configuration (`jsRuntime.snapshotUserlandCode`). It decides which agents opt in.\n- **Sidecar.** Owns the snapshot. It builds the snapshot once, caches it process-wide, and seeds each session's isolate from it. The SDK runs inside the isolate under the same [permission policy](/docs/permissions) as any guest code — snapshotting grants the SDK no extra capability.\n- **Executor.** The agent adapter restores into an isolate where the SDK is already on the global, reads it, and proceeds. It is untrusted guest code as always.\n\n## The pipeline\n\n### 1. Bundle the SDK to one snapshottable unit\n\nThe agent SDK and its transitive dependencies are bundled (esbuild, IIFE) into a single file shipped with the agent package (`dist/sdk-snapshot.js`). The bundle evaluates the SDK and publishes its public API on a well-known global (e.g. `globalThis.__PI_SDK_RUNTIME__`). Node builtins stay external (resolved by the bridge's in-snapshot polyfills); heavy provider SDKs that are only reached via dynamic `import()` stay lazy and load post-restore from the VFS.\n\n### 2. Capture the evaluated SDK into the snapshot\n\nThe sidecar runs the bridge, then the SDK bundle, in one snapshot-creation context, then serializes the heap. The result is a startup blob containing both. Per-session configuration (cwd, model, API keys) is **not** captured — it is injected after restore, so one blob serves every session.\n\n### 3. Cache it process-wide, keyed by content\n\nThe blob is stored in a **sidecar-process-wide cache keyed by `sha256(bridge + bundle)`**. Any change to the bridge or the bundled dependency graph changes the key and triggers exactly one rebuild; an unchanged bundle is a cache hit. This is what makes it **build-once-per-sidecar**: the cache is shared across every VM and session in the process.\n\n### 4. Pre-warm so the first session is warm\n\nBuilding the snapshot is itself the expensive evaluation, just done once. To keep it off the session-create critical path, the sidecar **pre-warms** at VM creation: when a VM is configured with a snapshot bundle, the sidecar builds the blob into the cache *before* the first session is created. The first session then restores from a warm cache like every session after it.\n\n\u003CWarning>\n**Pre-warm and V8 initialization order**\nThe V8 platform must be initialized on a long-lived thread *before* any pre-warm runs. agentOS initializes the embedded runtime on the sidecar's main thread at startup. Initializing V8 lazily on a transient worker thread that then exits corrupts the platform and wedges later isolate creation — so the startup init is load-bearing, not incidental.\n\u003C/Warning>\n\n### 5. Restore a fresh isolate per session\n\nOn `createSession`, the agent's isolate is created from the cached blob. The SDK is already evaluated in the snapshot's default context, and each session gets a **fresh context cloned from it**. The adapter reads the SDK off the global instead of importing it. If no snapshot is configured — or snapshot creation fails — the adapter transparently falls back to the per-session dynamic-import path, so snapshotting never affects correctness, only latency.\n\n## Isolation\n\nEach session leases a **fresh context** cloned from the snapshot's default context. The captured SDK is shared read-only through the blob, but live state is not: a global, a captured-object mutation, or even a built-in prototype change made in one session is **not** observable in another. This is the same isolation guarantee as a non-snapshot session — a fresh isolate per session — and is covered by dedicated tests (a session that mutates `globalThis`, an SDK object, and `Array.prototype`, with a second session from the same snapshot seeing none of it).\n\n## Snapshot-safety: what an SDK must avoid\n\nA startup snapshot can only capture a pure JS heap. The SDK's **module-initialization** code (everything that runs at import time, before any function is called) must not, at top level:\n\n- Create a **native handle** — load a `.node` addon, instantiate WebAssembly, or produce any V8 *External* object (for example an ICU-backed `Intl.Segmenter` singleton). These cannot be serialized and abort snapshot creation.\n- Open an **fd, socket, timer, or worker**, or leave a **pending promise** at the end of evaluation.\n- Read **non-deterministic or per-session state** (`process.env`, cwd, model, `Date.now()`, `Math.random()`, a random UUID) into a module constant — it would be frozen to the build-time value.\n\nReal-world SDKs frequently break these by accident. agentOS makes such an SDK snapshottable with **build-time transforms in the bundle** that defer the offending work to first use (e.g. wrap a module-level native singleton in a lazy proxy, inline a top-level config-file read, convert eager fire-and-forget imports to synchronous module references). Each transform asserts the source shape it expects, so an upstream SDK change surfaces as a build error rather than a silent regression. The full author-facing rules live in the [Software Definition](/docs/custom-software/definition) reference.\n\n## Opt-in, per agent\n\nSnapshotting is **opt-in per agent**, via `agent.snapshot: true` on the [agent software descriptor](/docs/custom-software/definition), and requires the agent package to ship a snapshot-safe `dist/sdk-snapshot.js`. Today only the Pi agent opts in; other agents run the normal per-session import path. An agent qualifies by (1) being snapshot-safe and (2) building the bundle — there is nothing Pi-specific in the runtime mechanism.\n\n\u003CNote>\n**Current trade-off**\nThe bundle is currently delivered inline in the (trusted) VM config, which moves bytes onto VM creation. The intended refinement is to ship the bundle as a build-time blob the sidecar loads from the guest VFS by path, keeping the config small. Either way the snapshot is built once per sidecar and reused across sessions.\n\u003C/Note>","src/content/docs/docs/architecture/agent-sdk-snapshots.mdx","eac9412e8bdd154e","docs/architecture/agent-sessions",{"id":339,"data":341,"body":344,"filePath":345,"digest":346,"deferredRender":16},{"title":342,"description":343,"skill":16},"Agent Sessions","Internals of agent sessions: how a session is created and bound to a VM, how prompts and events flow from client to sidecar to agent adapter and back, the session lifecycle, and where session state lives.","This page is an internals deep-dive on how agent sessions work under the hood. For the usage API (creating sessions, sending prompts, streaming responses, replaying events), see [Sessions](/docs/sessions).\n\nA session is a long-lived conversation with an agent (such as [Pi](https://github.com/mariozechner/pi-coding-agent)) running inside a VM. Where a bare `exec()` / `run()` starts a fresh guest process and returns when it exits, a session keeps an agent process alive across many prompts, streams its output back as events, and persists a transcript that survives sleep/wake cycles. Everything below describes the machinery that makes that possible while keeping the agent inside the same isolation boundary as any other guest.\n\n## Where a session sits in the component model\n\nThe [three components](/docs/architecture#the-big-picture) are unchanged for sessions: a trusted **client**, the trusted **sidecar** that owns the kernel, and the untrusted **executor** that runs guest code. An agent session adds one more layer on the guest side of the boundary:\n\n- **Client.** Calls `createSession`, `sendPrompt`, and the rest of the session API. It never runs the agent itself; it drives the session over the wire protocol.\n- **Sidecar / kernel.** Spawns the agent as a kernel-managed process inside the VM, owns the session's I/O, applies the permission policy on every syscall the agent makes, and persists the transcript.\n- **Agent adapter.** A per-agent-type shim, inside the VM, that translates between the session protocol and the specific agent's native interface. It normalizes the agent's output into the [Agent Communication Protocol (ACP)](/docs/sessions) so every agent type produces the same event shape.\n- **Executor.** The agent process itself plus any tools it spawns. It is untrusted guest code like any other: its file reads, child processes, and network calls all flow through the kernel.\n\nThe key consequence: an agent is not privileged. It is a guest process that happens to be long-lived and conversational. Its capabilities are exactly the VM's [permission policy](/docs/permissions), nothing more.\n\n## Creating a session and binding it to a VM\n\nA session is always created against an existing VM. The client resolves a VM handle (for example `client.vm.getOrCreate([...])`) and calls `createSession(agentType, options)` on it. Under the hood:\n\n1. **The request crosses the wire** (client to sidecar) carrying the agent type and the session options: `env`, `cwd`, `mcpServers`, `additionalInstructions`, and `skipOsInstructions`.\n2. **The kernel boots the VM** if it is not already running, with its bootstrapped virtual filesystem.\n3. **The sidecar selects the agent adapter** for the requested type and spawns the agent as a kernel-managed process inside that VM. Because the VM does not inherit the host `process.env`, the agent only sees the `env` passed in the options (this is why API keys must be supplied explicitly). The process starts in `cwd` (default `/home/agentos`).\n4. **The session is registered** in the VM with a `sessionId`, and the adapter performs its handshake with the agent to discover `capabilities` and `agentInfo`.\n5. **The handle returns** that metadata to the client.\n\nThe session is bound to that VM for its lifetime. The agent process, its working directory, and its persisted transcript all live inside the VM's isolation domain. A VM can host several sessions at once: each gets its own agent process, but they share the one VM's filesystem (see [Multiple sessions](/docs/sessions#multiple-sessions)). Two sessions in two different VMs share nothing, exactly as described in the [isolation model](/docs/architecture).\n\n\u003CNote>MCP servers configured on a session follow the same boundary. A `local` MCP server runs as a child process inside the VM (kernel-managed, gated by the permission policy); a `remote` MCP server is reached over the network, so its traffic flows through the kernel socket table and is subject to the network allowlist.\u003C/Note>\n\n## How a prompt flows: client to agent and back\n\nSending a prompt is a request in one direction with a stream of events flowing back in the other. The lifecycle of a single prompt extends the general [lifecycle of a request](/docs/architecture):\n\n1. **The client calls `sendPrompt(sessionId, text)`.** The request crosses the wire to the sidecar (hop one).\n2. **The sidecar routes it to the session's agent adapter,** which translates the prompt into the agent's native input and writes it to the running agent process.\n3. **The agent works the turn.** As it thinks, calls tools, edits files, and produces output, every action it takes is a guest syscall back into the kernel (hop two): file reads/writes hit the VFS, tool subprocesses are kernel-managed, and network calls go through the socket table under the allowlist.\n4. **The adapter normalizes the agent's output into ACP events.** Each event is assigned a monotonically increasing sequence number, appended to the session's event log, and persisted.\n5. **Events stream back to the client** as `sessionEvent` notifications, carrying the `sessionId` and the ACP `event` (its `method` and `params`). This is why the docs recommend subscribing to `sessionEvent` before calling `sendPrompt`: events emitted early in the turn would otherwise be missed.\n6. **The turn resolves.** When the agent finishes the turn, `sendPrompt` resolves with the reply.\n\n`cancelPrompt(sessionId)` interrupts an in-progress turn: the request crosses to the sidecar, which signals the agent process to stop the current turn through the adapter, leaving the session itself alive for the next prompt.\n\n```\nclient sidecar / kernel agent adapter agent (executor)\n | sendPrompt | | |\n | --------------------> | route to session | |\n | | ---------------------------> | native input ---> |\n | | | | (thinks, calls\n | | \u003C--- syscalls (VFS, procs, sockets) ------------ | tools, edits)\n | | | \u003C-- native output |\n | sessionEvent (ACP) | persist + assign seq | |\n | \u003C------------------- | \u003C-------- ACP events ------- | |\n | ...stream... | | |\n | resolve(reply) | | |\n | \u003C------------------- | | |\n```\n\n## Session lifecycle\n\nA session moves through these states, all driven by client calls over the wire:\n\n- **Active.** Created and bound to a running VM, with a live agent process. Prompts can be sent and events stream back.\n- **Suspended.** When the VM sleeps, the agent process is torn down but the session's persisted transcript remains in storage. `resumeSession(sessionId)` reconnects: the kernel wakes the VM, re-spawns the agent, and rebinds the session so prompts can continue.\n- **Closed.** `closeSession(sessionId)` gracefully shuts down the agent process and releases its in-VM resources, but leaves the persisted transcript intact so history can still be queried.\n- **Destroyed.** `destroySession(sessionId)` removes the session and all of its persisted events. This is irreversible.\n\nBecause the transcript is persisted, closing or suspending a session is not the same as losing it: the event history can be read back later, even when the VM is not running.\n\nRuntime configuration (`setModel`, `setMode`, `setThoughtLevel`) mutates an active session in place by sending the change through the adapter to the live agent, without restarting the session.\n\n## Resuming a suspended session\n\nWhen a VM sleeps the agent process is destroyed, but the session registry and the transcript survive in SQLite. `resumeSession(sessionId)` (or simply prompting a suspended session) rebinds the stable, client-facing `sessionId` to a freshly spawned agent. Resume is **lazy** (it runs on the first prompt to a non-live session) and **capability-driven** (the orchestrator never special-cases an agent by name, only by what it advertises). There are two paths:\n\n- **Native ACP resume (optimization).** If the agent advertises ACP `loadSession`/`resume` and its own store survived on the durable root, the sidecar issues `session/load` and the agent restores its full context itself. The `sessionId` is unchanged.\n- **Universal transcript fallback.** If the agent has no native resume, or its store did not survive, the sidecar reconstructs a Markdown transcript from the recorded events, writes it into the VM (for example `/root/.agentos/threads/\u003CsessionId>.md`), starts a fresh agent, and prefixes the next prompt with a pointer to that file. Because this needs only file-read tools it works for any agent with no per-agent code, at the cost of pointing the agent at the transcript rather than pre-loading it into context.\n\nResume depends on a **durable root filesystem**. The RivetKit actor configures one automatically (its SQLite-backed root), so transcript capture and resume work out of the box. A direct `AgentOs` SDK user on the default in-memory root has no durable store: transcript capture is a no-op and context cannot be restored, so configure a durable root explicitly if you need resume outside the actor.\n\n## Adapter crashes and bounded auto-restart\n\nIf the agent process exits without `closeSession()` — any spontaneous exit, including exit code 0 — the sidecar treats it as a crash, not a lifecycle transition. Crashes are detected both mid-request (the exchange loop observes the process exit) and while idle (the next write to the dead adapter fails). The sidecar logs the exit with its code and a stderr tail, emits an `AcpAgentExitedEvent` to the host (`onAgentExit` in the SDK, `agentCrashed` on the actor), and attempts an **in-place restart, bounded to 3 attempts per session**:\n\n- **Native re-attach only.** The restart relaunches the adapter with the exact parameters of the original launch, re-probes capabilities with a fresh `initialize`, and — if the agent advertises `loadSession`/`resume` — re-attaches the **same `sessionId`** via `session/load`. Clients keep their handle and the session stays active. There is deliberately no `session/new` fallback tier here: a fallback would produce a different live session id that an in-place restart cannot remap transparently. That path belongs to lazy resume (above), which owns the external→live remap.\n- **Eviction otherwise.** If the adapter has no native resume capability, the restart fails, or the budget is exhausted, the session record is evicted — the same teardown as before auto-restart existed. The persisted transcript is untouched, so the actor's lazy resume can still recover the conversation on the next prompt.\n- **The interrupted request still fails.** A prompt in flight when the adapter died is never replayed (the turn may have had side effects); its error names the restart outcome so the caller knows whether a retry will succeed.\n\nEach event carries `{ exitCode, restart, restartCount, maxRestarts }`, where `restart` is `\"restarted\"`, `\"unsupported\"`, `\"failed\"`, or `\"exhausted\"`; only `\"restarted\"` leaves the session usable. See [Debugging](/docs/debugging#agent-crashes-onagentexit) for capturing these from the SDK.\n\n## Where session state lives\n\nSession state spans two tiers:\n\n- **In-memory, while the VM runs.** The running agent process holds the live conversation, and the sidecar keeps the session's recent event log with sequence numbers, the basis for live reconnection: a client tracks the last sequence number it processed and asks for everything after it, so no events are dropped or duplicated across a reconnect.\n- **Persisted in SQLite, independent of the VM.** Every ACP event is written to a SQLite-backed transcript store inside the VM, keyed by `sessionId` and sequence number. This tier survives sleep/wake and VM shutdown. `listPersistedSessions()` and `getSessionEvents(sessionId)` read from it and work even when the VM is not running, which is what makes transcript-history UIs possible without keeping a VM warm.\n\nSee [Replay events](/docs/sessions#replay-events) for replaying a session's persisted events.\n\nThe transcript living inside the VM keeps session state on the same side of the boundary as the agent that produced it: it is part of the VM's isolation domain, not the client's. The client only ever sees it by asking the sidecar for it over the wire.\n\n## Where to go next\n\n- [Sessions](/docs/sessions): the usage API for creating sessions, sending prompts, and replaying events.\n- [Architecture](/docs/architecture): the component model, request lifecycle, and isolation model that sessions build on.\n- [Permissions](/docs/permissions): the policy the kernel enforces on every syscall an agent makes.\n- [Replay events](/docs/sessions#replay-events): in-memory versus persisted event replay.","src/content/docs/docs/architecture/agent-sessions.mdx","6f588d17c4849062","docs/architecture/compiler-toolchain",{"id":347,"data":349,"body":352,"filePath":353,"digest":354,"deferredRender":16},{"title":350,"description":351,"skill":16},"Compiler Toolchain","How agentOS compiles its command suite to WebAssembly: Rust coreutils via cargo and C programs via wasi-sdk, linked against a patched wasi-libc plus the wasi-ext bindings, and how the resulting .wasm files become the guest's commands.","The commands a guest runs through [process execution](/docs/processes), the shell\n(`sh`) and the coreutils behind it, are not native host binaries. They are\nWebAssembly modules compiled ahead of time and mounted into the VM. This page\ncovers how that command suite is produced: which toolchains compile it, what it\nlinks against, and how the resulting `.wasm` files become the guest's commands.\n\nFor *why* WASM is a first-class guest and *how* it presents a POSIX surface at\nruntime, see the [WASM VM](/docs/architecture/posix-syscalls) page. This page is the build-side\ncounterpart: it documents the toolchain that emits binaries carrying both\n[the host-import layer and the WASI shim](/docs/architecture/posix-syscalls).\n\n## Target: `wasm32-wasip1`\n\nEverything in the command suite is compiled to a single target,\n`wasm32-wasip1`: the WASI preview 1 ABI on the 32-bit WebAssembly architecture.\nPicking one target for the whole suite means a single libc, a single set of\nhost import declarations, and a single runtime shim can serve every command.\n\nA guest module built for this target expects standard WASI (preopened file\ndescriptors, clocks, randomness, file I/O) plus the extra agentOS import modules\ndescribed below. Both halves are satisfied at runtime by the kernel-backed\nruntime; nothing in a compiled command reaches a real host syscall.\n\n## Two source languages, two compilers\n\nThe suite is heterogeneous: most tools are Rust, some are C. Each language uses\nits own compiler driver, but both emit the same `wasm32-wasip1` ABI and link\nagainst the same sysroot, so the outputs are interchangeable at runtime.\n\n- **Rust coreutils** are built with **`cargo`** targeting `wasm32-wasip1`. Rust's\n standard library already has first-class support for this target, so the\n coreutils crates compile with an ordinary cross-compile invocation.\n- **C programs** are built with the **`wasi-sdk`** toolchain, a packaged\n `clang` plus sysroot tuned for WASI. C tools that have no Rust equivalent (or\n that are easier to carry as upstream C) go through this path.\n\n```bash\n# Rust coreutils\ncargo build --target wasm32-wasip1 --release\n\n# C programs via wasi-sdk, linked against the patched libc + wasi-ext\n$WASI_SDK/bin/clang --target=wasm32-wasip1 \\\n --sysroot=$WASI_SYSROOT \\\n -lwasi-ext \\\n tool.c -o tool.wasm\n```\n\n## What every binary links against\n\nRegardless of source language, each command links against the same two pieces.\nTogether they give a single binary both the standard WASI calls and the agentOS\nprocess / user / network extensions.\n\n- **A patched `wasi-libc`.** The libc is the WASI standard library, modified so\n that the calls a normal command-line program performs resolve against the\n agentOS surface instead of failing or hitting unimplemented stubs. This is the\n same patched libc the [Layer 2 shim](/docs/architecture/posix-syscalls) adapts at runtime; the\n build side and the runtime side are two ends of the same contract.\n- **The `wasi-ext` bindings.** These declare the extra WebAssembly import\n modules (`host_process`, `host_user`, `host_net`, and the small\n `host_sleep_ms` binding) that base WASI cannot express. Linking `wasi-ext`\n into a binary is what lets its libc emit `fork` / `exec`, `getuid` / `getgid`,\n and `connect` / `listen` as ordinary-looking syscalls that the host runtime\n then services through the kernel. See\n [Layer 1: custom host import modules](/docs/architecture/posix-syscalls) for the runtime half.\n\n\u003CNote>\nThe import declarations are compile-time only: linking `wasi-ext` tells the\nmodule *which* host imports to reference, but the calls are still routed through\nthe kernel and gated by the VM's [permission policy](/docs/permissions) at\nruntime. Building against `host_net` does not grant network access.\n\u003C/Note>\n\n## From `.wasm` to a guest command\n\nThe compiler toolchain's product is a set of `.wasm` files, one per command.\nThose files are what the runtime mounts as the guest's executables: when a guest\ninvokes `ls`, `sh`, or any other bundled tool, the kernel resolves the name to\nthe corresponding module, instantiates it with the host imports and the WASI\nshim wired in, and runs it as a [child process](/docs/processes) with real\nprocess, user, and network semantics, all virtualized.\n\nThe same path is open to your own programs. A program you compile for\n`wasm32-wasip1` runs as a guest command exactly like the bundled ones; link the\n`wasi-ext` bindings if it needs processes, users, or sockets, and leave them out\nfor a pure-compute tool. Heavy native binaries that are not yet available as\nWASM belong in a [mounted sandbox](/docs/sandbox) instead.\n\n## Recommendations\n\n- Use the bundled WASM coreutils and `sh` for normal shell workloads; they\n already carry the patched libc and the `wasi-ext` extensions.\n- To ship your own command, compile it for `wasm32-wasip1` with `cargo` (Rust)\n or the `wasi-sdk` `clang` (C), and link `wasi-ext` only if it needs the\n process / user / network host imports.\n- Keep the build and runtime contracts aligned: the patched `wasi-libc` and the\n `wasi-ext` import declarations a binary is compiled against are the same ones\n the [WASM VM](/docs/architecture/posix-syscalls) runtime expects to satisfy.","src/content/docs/docs/architecture/compiler-toolchain.mdx","49ef24cfa33c5d1f","docs/architecture/filesystem",{"id":355,"data":357,"body":359,"filePath":360,"digest":361,"deferredRender":16},{"title":111,"description":358,"skill":16},"Internals of the kernel VFS: the overlay/mount/root engines, how guest fs syscalls are routed and confined, WASM preopens, and mount confinement against symlink and .. escapes.","This page is an internals deep-dive on the **kernel virtual filesystem (VFS)**: how it is layered, how a guest `fs` syscall is routed through it, and how guest I/O is confined to the VM. For the user-facing API (reading, writing, mounting, persistence), see [Filesystem](/docs/filesystem).\n\nThe invariant this whole subsystem exists to uphold: **every guest filesystem operation is serviced by the kernel-owned VFS, never by a real host capability.** There is no host disk reachable from the guest. The VFS presents normal Linux semantics to tools while keeping every byte inside the kernel.\n\n\u003CNote>The security boundary is sidecar to executor. The VFS lives inside the trusted sidecar; the guest in the executor only ever *asks* for a filesystem operation. Confinement is the kernel's job, not the guest's. See the [Security Model](/docs/security-model) for the full threat model.\u003C/Note>\n\n## Where the VFS sits\n\nA guest `fs` call never touches the host. The path is always:\n\n```\nguest fs call (executor)\n -> kernel syscall (crosses sidecar \u003C-> executor boundary)\n -> VFS engine resolves the path\n -> backing store services the operation\n -> result returns to the executor\n```\n\n- The executor holds **no** filesystem capability of its own. It issues a syscall and blocks for the reply.\n- The kernel checks the applied permission policy for the filesystem scope before servicing the request.\n- The VFS resolves the path against the VM's layered engines, then services the operation against the engine that owns that path.\n\nBecause every byte is mediated here, two properties fall out for free: the guest can never reach the real host disk, and one VM's filesystem is never visible to another VM. Isolation is per-VM.\n\n## The VFS engines\n\nThe per-VM filesystem is not a single flat store. It is a tree of **engines**, each responsible for a subtree of the namespace. A path is resolved by walking from the root engine down to whichever engine owns the deepest matching prefix, then handing the remainder of the path to that engine.\n\n- **Root engine.** Owns `/` and the base namespace. Every VM boots with a root filesystem bootstrapped from a snapshot, so the guest starts against a populated POSIX tree (the default working directory is `/home/agentos`).\n- **Overlay engine.** Composes layers so writes land in a writable upper layer while reads fall through to a lower layer. This is how a read-mostly base can be presented as writable to the guest without mutating the shared lower layer.\n- **Mount engine.** Grafts a distinct backing store onto a guest path (a mount point). Below the mount point, operations are routed to that mount's backend instead of the parent engine. This is the mechanism behind in-memory, host-directory, S3, and Google Drive mounts.\n\nResolution is **longest-prefix wins**: if `/mnt/data` is a mount and the guest opens `/mnt/data/file`, the mount engine services it; anything outside `/mnt/data` stays with the parent (root/overlay) engine.\n\n```\n/ \u003C- root engine (bootstrapped from snapshot)\n|- home/user/... \u003C- root / overlay\n|- mnt/\n| |- scratch/... \u003C- mount engine -> in-memory backend\n| |- code/... \u003C- mount engine -> host-directory backend (read-only)\n| \\- data/... \u003C- mount engine -> S3 backend\n\\- ...\n```\n\nThe base layer is in-memory and per-VM; the runtime transparently persists it to backing storage so it survives sleep/wake. Mounts are pluggable: any guest path can be backed by the host, a remote, or a cloud store. See [Mounting filesystems](/docs/filesystem#mounts) for the user-facing config.\n\n## Routing a guest syscall\n\nWhen the guest calls, say, `readFileSync(\"/mnt/data/report.csv\")`:\n\n1. **Permission check.** The kernel verifies the filesystem scope is granted for that operation. Nothing is bound by default; access is denied until opted in (see [Permissions](/docs/permissions)).\n2. **Engine resolution.** The VFS walks the namespace and selects the engine owning the longest matching prefix (`/mnt/data` -> the S3 mount engine).\n3. **Path normalization and confinement.** The remainder of the path is normalized within the owning engine's root. `.` and `..` segments are resolved *before* the operation reaches the backend, so the request cannot climb above the engine's root.\n4. **Backend operation.** The owning engine's backend services the read/write/stat/etc. against its store (in-memory pages, the persisted base, a host directory, S3, ...).\n5. **Reply.** The result crosses back to the executor, which unblocks.\n\nHost-side APIs (`agent.writeFile`, `agent.readFile`) enter the *same* VFS from the trusted side, which is why the host can seed and read files the guest sees, without ever exposing the real host disk to the guest.\n\n## Mount confinement\n\nA host-backed mount (host directory, S3, ...) comes from trusted config, so its existence, target, and credentials are not attack surface. What *is* in scope is the guest-driven traffic through it: the guest must not be able to use a mounted path to reach bytes outside the mount root. Confinement is enforced by the kernel, on every operation:\n\n- **`..` traversal.** Path segments are normalized relative to the mount root before the backend sees them. A guest path like `/mnt/code/../../etc/passwd` cannot resolve above the mount root; it is clamped to the mount's own subtree (and, above the mount point, handed back to the parent engine, which is itself the kernel VFS, not the host).\n- **Symlinks.** Symlink resolution (`realpath` following) is performed by the kernel against the *virtual* namespace, not the host's. A symlink inside a host-directory mount cannot be used to escape the mount root onto the wider host filesystem; the resolved target is re-confined to the mount root.\n- **Path aliasing / TOCTOU.** Because resolution and confinement happen inside the kernel on each operation, there is no window where the guest resolves a path and the backend later acts on a different one. The guest sees only the mounted subtree, never the wider host filesystem.\n\nMounts for host and remote backends are **read-only by default**; a writable mount must be opted into explicitly. The `readOnly` flag is enforced at the engine, so a write syscall to a read-only mount fails inside the kernel rather than reaching the backend.\n\n\u003CNote>\"Trusted mount, untrusted traffic\": the mount's target is trusted configuration, but the guest drives I/O through it, so confining guest operations to the mount root (`..`, symlink, TOCTOU, path-aliasing) is squarely in scope and enforced by the kernel.\u003C/Note>\n\n## WASM preopens\n\nWASI does not grant a WASM guest an ambient filesystem. Instead, the host hands the module a set of **preopened directories**: capability handles to specific subtrees, and the guest can only reach paths reachable from a preopen.\n\nIn agentOS these preopens are wired to the **same kernel VFS** rather than to host directories:\n\n- A preopen maps a guest-visible path to a VFS subtree. File descriptors derived from it are serviced by the VFS engines above, with the same confinement rules.\n- The WASM guest therefore sees the virtualized filesystem (root snapshot, overlays, mounts) through standard WASI calls, with no host filesystem handle anywhere in the chain.\n- Confinement composes: a preopen rooted at a mount point inherits that mount's `..`/symlink confinement, because resolution still runs through the kernel VFS.\n\nThe result is that WASI filesystem access and the V8/Node `fs` path converge on one virtual filesystem, so both executor flavors get identical isolation and identical Linux semantics.\n\n## Where to go next\n\n- [Filesystem](/docs/filesystem): the user-facing API for reading, writing, mounting, and persistence.\n- [Architecture](/docs/architecture): the components, trust boundary, and kernel-owned syscall paths.\n- [Permissions](/docs/permissions): the filesystem scope the kernel checks on every operation.\n- [Security Model](/docs/security-model): the full trust model and threat boundary.","src/content/docs/docs/architecture/filesystem.mdx","6611b9713df06bfc","docs/architecture/limits-and-observability",{"id":362,"data":364,"body":367,"filePath":368,"digest":369,"deferredRender":16},{"title":365,"description":366,"skill":16},"Limits & Observability","How agentOS bounds resources, applies backpressure, warns before a limit is hit, and surfaces it all to the host.","agentOS runs untrusted, AI-generated code inside disposable VMs. Every resource\nthat code can consume is **bounded by default**, and every bound is designed to\n**warn before it is hit**, **fail with a clear error when it is**, and stay\n**inspectable** from one place. This page explains how the limits, backpressure,\nlogging, and observability pieces fit together across the stack.\n\n## Where limits live\n\nLimits are owned by **secure-exec** (the VM runtime) and **forwarded** by agentOS\n— the agentOS layer does not reimplement enforcement, it exposes the knobs and\nsurfaces the signals.\n\n| Layer | Responsibility |\n| --- | --- |\n| secure-exec kernel | Enforces per-VM resource caps (memory/heap, CPU time, fds, processes, sockets, filesystem bytes, …). |\n| secure-exec sidecar | Owns the bounded queues between the guest, the runtime, and the host; applies backpressure; tracks usage. |\n| agentOS client | Forwards `limits` config to the VM and surfaces limit signals to the caller. |\n\n## Three guarantees for every limit\n\nEvery bound — a resource cap, a bounded queue, a timeout, a payload size —\nfollows the same contract:\n\n1. **Bounded by default.** Nothing is unbounded out of the box. Memory is capped\n at ~128 MiB per isolate (Cloudflare Workers parity), CPU is bounded, and every\n queue has a fixed capacity. Operators may *raise* a cap, but never get an\n unbounded default.\n2. **Warn on approach.** As usage crosses a threshold (default **≥80%** of\n capacity), a structured warning is emitted — once per crossing, re-armed only\n after it drains back below 50% (hysteresis), so a busy limit logs once, not on\n every operation.\n3. **Clear, typed error on breach.** Exceeding a limit produces an error that\n names the limit, the observed-vs-cap value, and the config path to raise it —\n never a bare `EAGAIN`, a silent drop, or a crash.\n\n## Backpressure, not catastrophe\n\nThe path from guest code to the host is a **chain of bounded queues**: the V8\nruntime → a per-session frame channel → the V8→host event channel → the sidecar\nstdout frame queue → the host. When a queue fills (a slow host consumer, a chatty\ntool turn), the producer **blocks until the consumer drains a slot** — clean\nbackpressure that flows all the way back to the guest. A full queue never\ndestroys the session, silently drops data, or crashes the sidecar; a genuinely\ndead consumer surfaces as a typed terminal error instead.\n\nBuffer capacities are sized so that *transient* bursts are absorbed without ever\nengaging backpressure; backpressure is the safety net for a genuinely stuck\nconsumer, not a normal-operation event.\n\n## The limit registry\n\nAll bounded limits register with a single in-process **limit registry**. Each\nregistered limit tracks its live depth, high-water mark, and capacity, and emits\nthe near-capacity warning described above. This gives the runtime one place to\nanswer two questions:\n\n- *Is a limit about to be hit?* — the registry fires the approach warning.\n- *What is the current usage of everything?* — a registry snapshot lists every\n limit's depth / high-water / capacity / fill-percent for debugging.\n\nA CI audit fails the build if any limit-shaped constant is not classified and —\nfor operator-tunable ones — wired to a config field, so \"is everything bounded\nand config-wired?\" is verified mechanically rather than by review.\n\n## Logging & host visibility\n\nsecure-exec logs to **stderr** (never stdout — stdout is the framed wire\nprotocol). The default level is `WARN`, tunable with the `SECURE_EXEC_LOG`\nenvironment variable (`error` to quiet, `debug` for per-limit usage snapshots).\nNear-limit warnings and backpressure events therefore show up in the sidecar's\nstderr stream, which agentOS forwards to the host.\n\nThe limit registry also exposes a structured **warning sink**: a callback that\nfires on the same edge as the log, carrying `{ name, category, observed,\ncapacity, fillPercent }`. This is the foundation for host-facing limit\nobservability — a structured \"a limit is approaching capacity\" signal rather than\na parsed log line.\n\n## See also\n\n- [Resource Limits](/docs/resource-limits) — the full `limits` config surface.\n- [Processes](/docs/architecture/processes) and [Sessions & Persistence](/docs/architecture/sessions-persistence) — the layers the queue chain runs through.","src/content/docs/docs/architecture/limits-and-observability.mdx","da92f833b195bf95","docs/architecture/networking",{"id":370,"data":372,"body":375,"filePath":376,"digest":377,"deferredRender":16},{"title":373,"description":374,"skill":16},"Networking","How the kernel socket table works: a single VM-local transport that carries host, JavaScript, and WASM traffic, where fetch / net / dns route through it, how egress policy and loopback confinement are enforced, and how preview URLs are served.","This is the internals view of agentOS networking: the kernel socket table, the layers a request crosses, and where policy is enforced. For the user-facing API (`vmFetch`, preview URLs, the confinement model from a caller's perspective), see [Networking & Previews](/docs/networking). For the trust boundary this all sits inside, see [Architecture](/docs/architecture).\n\nThe governing rule is that there is exactly **one authoritative transport for everything VM-local**: the kernel socket table. No part of guest networking opens a real host socket on its own. Guest `fetch()`, `node:http`, `node:net`, WASM TCP clients and servers, and host-into-guest requests (`vmFetch` / `rt.fetch`) all target the same listener table.\n\n## The kernel socket table\n\nThe socket table is the floor of the stack and the only component that actually moves bytes between two in-VM endpoints. It is per VM, so two VMs never share a listener or a connection.\n\n- It exposes POSIX-style primitives: `socket_create`, `socket_bind_inet`, `socket_connect_inet_loopback`, `socket_read`, `socket_write`, `poll_targets`.\n- Every call is **owner-checked** (the calling process must own the descriptor) and **resource-accounted** against the VM's limits.\n- Failures return correct POSIX errnos (`ECONNREFUSED`, `EACCES`, …) so guest code branches the way it would on real Linux.\n- Connecting pairs two in-VM sockets and shuttles bytes between them. No host networking happens at this layer.\n\nBecause every server is a kernel TCP listener, a client never needs to know whether the server it is talking to is JS, WASM, raw TCP, or HTTP. HTTP is layered on top of kernel TCP bytes, so every listener lives in the one table and is reachable identically.\n\n\u003CNote>An earlier design carried two listener models at once: stream-mode listeners (`net.createServer`, WASM) on real kernel TCP sockets, and object-mode HTTP listeners (`http.createServer`) on a separate table that exchanged JSON request/response objects over stream events. A second guest process could not reach the object-mode table reliably, because the client expected byte-stream TCP semantics while the server only spoke object-mode dispatch. The current architecture removes the second model: everything is one socket table.\u003C/Note>\n\n## The four layers\n\nA request passes through four layers. Only the top and bottom understand HTTP; the middle two move bytes and enforce policy.\n\n| Layer | Role | Trust | Lives in |\n| --- | --- | --- | --- |\n| 4 · Guest bridge | `node:http` / `node:net` / `fetch` / undici shim | untrusted (V8 isolate) | `crates/execution/assets/v8-bridge.source.js` |\n| 3 · Sync-RPC dispatch | routes `net.connect`, `net.http_request`, `net.listen`, … | trusted | `crates/sidecar/src/service.rs` |\n| 2 · Execution & enforcement | listener state, host fetch client, permission checks | trusted (TCB) | `crates/sidecar/src/execution.rs` |\n| 1 · Kernel socket table | `bind` / `listen` / `connect` / `read` / `write`, loopback routing | trusted (TCB floor) | `crates/kernel/src/socket_table.rs`, `kernel.rs` |\n\n### Layer 1: kernel socket table\n\n`crates/kernel/src/kernel.rs` exposes the primitives above. Loopback routing is the heart of VM-local networking: `socket_connect_inet_loopback` only succeeds against a socket that is actually bound and listening in the same VM's table; otherwise it returns `ECONNREFUSED`. Resource-limit checks run before the two sockets are paired.\n\n### Layer 2: sidecar execution (enforcement point / TCB)\n\n`crates/sidecar/src/execution.rs` is where policy is applied. Two roles matter for networking:\n\n- **Listener state.** `build_javascript_socket_path_context` walks every active process and records what is listening on which port, including a map of HTTP loopback targets keyed by `(family, port)`. This is the source of truth a connect consults to learn that, say, \"port 3000 is an HTTP server owned by process X, server Y.\"\n- **Host fetch client.** When the host calls `vmFetch` / `rt.fetch()`, the sidecar resolves the target to a VM-owned kernel listener, opens its own kernel socket, connects over loopback, and speaks HTTP/1.1 to the guest server. This is the only HTTP client that lives in the sidecar (the host has no guest isolate to do framing for it).\n\n### Layer 3: sync-RPC dispatch\n\n`crates/sidecar/src/service.rs` routes the bridge calls guest code makes. The guest-to-guest loopback HTTP path lands here as `net.http_request`. It is the most security-sensitive RPC, so it is guarded in order:\n\n1. The host must be a loopback address.\n2. The applied network policy must permit the operation.\n3. The requested `(process_id, server_id)` must match a listener that is currently live.\n\nThat last check stops a guest from forging a target to reach a process it should not.\n\n### Layer 4: guest bridge\n\n`crates/execution/assets/v8-bridge.source.js` is the Node-compatibility shim inside the untrusted V8 isolate. It presents `node:http`, `node:net`, `fetch`, and undici to guest code and translates them into Layer 3 bridge calls. `http.createServer()` is implemented on top of `net.Server`: each accepted byte socket is parsed as HTTP and dispatched to the guest's request handler.\n\n## How fetch, net, and dns route through it\n\n- **`node:net` (raw TCP).** `net.connect` / `net.createServer` map directly onto kernel `connect` / `bind` + `listen`. The bytes are the payload; no framing is added.\n- **`node:http` and `fetch`.** A guest HTTP server is a `net.Server` whose accepted sockets are HTTP-parsed in the bridge. A guest HTTP client runs undici over a kernel-backed dispatcher (or a raw serializer for the loopback fast path). Either way the bytes travel as kernel TCP.\n- **DNS.** Name resolution is serviced by the kernel resolver, not the host. Outbound connections that leave the VM resolve through it, and the resolved addresses are then filtered by the egress allowlist (see below). DNS pinning ties the connection to the address that was checked, closing the resolve-then-reconnect TOCTOU gap.\n\n### Where HTTP meets TCP\n\nThere is no shared HTTP/TCP translation module. Because the wire between every endpoint is raw TCP bytes through the kernel, HTTP is framed and deframed **at each edge that speaks HTTP**. The kernel (Layer 1) and the sidecar routing (Layer 2) never parse HTTP. There are three independent codecs, one per kind of endpoint:\n\n| Endpoint | Lives in | Encode / decode |\n| --- | --- | --- |\n| Guest HTTP server | guest bridge | `parseLoopbackRequestBuffer` (bytes to object), `serializeLoopbackResponse` (object to bytes), wired per accepted socket by `attachHttpServerSocket` |\n| Guest HTTP client | guest bridge | undici over a kernel-backed dispatcher, or `serializeRawHttpRequest` + `waitForRawHttpResponse` |\n| Host fetch client | sidecar execution | `serialize_kernel_http_fetch_request` (request to bytes), `parse_kernel_http_fetch_response` (bytes to JSON) |\n\nA WASM HTTP server or client does its own framing in guest code (reading the request line, writing a response with standard C socket calls). The kernel does not help it; it is just bytes, the same as for the JS endpoints.\n\n## Data flows\n\n- **Host to guest (`vmFetch` / `rt.fetch`).** The sidecar resolves the port to a VM-owned kernel listener, opens a sidecar-owned kernel socket, connects over loopback, serializes the request bytes, drives the target process forward so it can accept and respond, then parses the response bytes back into the host response object. It is **fail-closed**: no DNS, no external networking, no host-loopback fallback. If no VM-owned listener exists, it returns a missing-listener error.\n- **Guest to guest.** `net.connect` goes through the sidecar, which returns a loopback HTTP target handle. The guest sends the request through `net.http_request`, which dispatches into the target process's request handler. Cross-process loopback passes through the enforcement point rather than taking an in-isolate shortcut.\n- **Cross-runtime (JS and WASM, either direction).** Client and server connect through a kernel loopback socket pair and exchange raw bytes. JS to WASM, WASM to JS, and WASM to WASM all use the same path; only the side that runs the HTTP codec differs.\n- **Guest outbound to host or external.** Connections that do not target a VM-owned listener take the external network path: permission checks, DNS pinning, then a real host `TcpStream`. Reaching a host loopback port still requires an explicit loopback exemption entry.\n\n## Egress policy and loopback confinement\n\nGuest networking is confined by three distinct controls plus the loopback-only default. The permission policy and limits are **trusted configuration**; the guest executor is the **untrusted subject** they bind.\n\n### Loopback-only by default\n\nGuest listeners are reachable only over loopback (`127.0.0.1` / `::1`) inside the VM.\n\n- Binding to `0.0.0.0` or `::` does not widen this: the kernel normalizes the unspecified address down to loopback, so the listener still answers only on loopback.\n- A connection that originates outside the loopback interface and targets a port the VM does not own is refused with `EACCES`, noting the port is not exempt.\n- This confinement is independent of the permission policy. Even with the network allowed, a guest server stays loopback-only unless its port is explicitly exempted.\n\n### Three stacked controls\n\nThese are often conflated but are separate. They stack, and a request must pass every one that applies:\n\n1. **Permission policy** (`network.listen` / `network.connect`). Decides whether the guest may open a listener or initiate an outbound connection at all. A blocked operation fails with `blocked by network.listen policy` or `blocked by network.connect policy`.\n2. **Loopback confinement.** Decides who may reach an already-permitted guest listener. By default only loopback inside the VM; a per-port exemption loosens it.\n3. **DNS / egress allowlist.** Constrains where permitted outbound connections may go. The kernel filters resolved addresses, blocking outbound access to restricted ranges, so an allowed `connect` can still be refused by destination.\n\nThe per-port loopback exemption belongs to layer 2 only. It is a trusted, per-port whitelist that *loosens* the default loopback confinement (for example, exposing an in-VM dev server beyond loopback). It is not an egress control and grants no outbound reach; layers 1 and 3 still apply. It is configured with `loopbackExemptPorts`, a list of ports that are exempt from the SSRF checks at layer 2; each listed port is reachable from outside the loopback interface, while the permission policy and egress allowlist continue to apply.\n\n### Trust and ownership\n\nEvery guest connect, listen, read, and write passes through sidecar ownership and kernel owner checks. Guest-to-guest loopback is allowed only when the destination is a VM-owned listener and the applied network policy permits the connect. Host-loopback access from guest code is separate and still requires a loopback exemption plus the applied network policy. Long-lived waits must not block the sync-RPC path, so the stack uses stream events, bounded polling, and kernel socket waits with explicit timeouts.\n\n\u003CNote>Host-to-guest requests bypass egress, not the table. `vmFetch` / `rt.fetch` terminate at the guest's loopback listener and never leave the VM, so they work even when guest egress (layer 3) or outbound `connect` (layer 1) is denied. They are host control-plane traffic, not guest egress, and only ever reach VM-owned listeners, while still going through the same kernel socket table as everything else.\u003C/Note>\n\n## Preview URLs\n\nA preview URL is port forwarding for a VM service: a time-limited, signed, publicly reachable URL that proxies HTTP to a port inside the VM. Mechanically it reuses the host-to-guest path:\n\n- A signed token is minted for a `(VM, port)` pair with an expiration, capped by `preview.maxExpiresInSeconds`. Tokens are stored in SQLite, survive sleep/wake cycles, and expired ones are cleaned up automatically.\n- An incoming request to the preview path is authenticated against the token, then proxied into the VM exactly like `vmFetch`: resolve the port to a VM-owned kernel listener, connect over loopback, frame HTTP/1.1, drive the target process, and stream the response back. The same fail-closed, VM-owned-listener-only rules apply.\n- CORS is enabled so browsers can reach preview URLs from any origin.\n- Revocation (`expireSignedPreviewUrl`) invalidates the token immediately, after which the proxy refuses the request before touching the socket table.\n\nBecause previews ride the host fetch path, they are subject to loopback confinement at the kernel but **not** to the guest egress allowlist: the request enters the listener from the host side and never becomes guest outbound traffic.\n\n## Where to go next\n\n- [Networking & Previews](/docs/networking): the `vmFetch` and preview URL API, with usage examples.\n- [Architecture](/docs/architecture): the client / sidecar / executor trust boundary this stack lives inside.\n- [Security Model](/docs/security-model): the full in-scope and out-of-scope threat model.","src/content/docs/docs/architecture/networking.mdx","9a3a667862c77ad4","docs/architecture/posix-syscalls",{"id":378,"data":380,"body":383,"filePath":384,"digest":385,"deferredRender":16},{"title":381,"description":382,"skill":16},"POSIX Syscalls","How agentOS extends WASI in two layers so WebAssembly guests behave like normal POSIX programs on top of the kernel.","Not everything inside an agentOS VM is JavaScript.

These bindings live\nin the `wasi-ext` crate and cover three areas:\n\n- **`host_process`**: process management. Spawn a child process (argv, env, inherited stdio fds, working directory), wait for a child to exit, and related file-descriptor operations. This is what gives a WASM `sh` real [child process](/docs/processes) semantics; spawns go through the kernel process table.\n- **`host_user`**: user and group identity (uid, gid, user info). Base WASI has no concept of a user; this lets tools that call `getuid` / `getgid` see the VM's virtualized identity.\n- **`host_net`**: TCP sockets (connect, listen, send, receive) through the kernel socket table, gated by the same [network permission policy](/docs/networking) as everything else. Base WASI has no general socket API.\n\nA small `host_sleep_ms` binding provides blocking sleep. Together these let a\nguest compiled for `wasip1` behave as if it had a process model, user identity,\nand a network, all virtualized.\n\n```c\n// Imported from the host runtime, declared by the wasi-ext bindings.\n// Guest libc calls these as if they were ordinary syscalls.\n__attribute__((import_module(\"host_process\"), import_name(\"proc_spawn\")))\nint host_proc_spawn(const char *argv, const char *envp, int cwd_fd);\n\n// getuid returns an errno; the uid is written through the out-pointer.\n__attribute__((import_module(\"host_user\"), import_name(\"getuid\")))\nint host_getuid(unsigned int *ret_uid);\n\n__attribute__((import_module(\"host_net\"), import_name(\"net_connect\")))\nint host_net_connect(int fd, const char *addr, int addr_len);\n```\n\n## Layer 2: the kernel-backed WASI shim\n\nThe second layer adapts the standard WASI calls themselves so that programs\nbuilt against a normal libc behave correctly inside the VM. The embedded shim:\n\n- **Routes stdio through the kernel.** `fd_read` / `fd_write` on the standard descriptors go through the kernel stdio bridge rather than host file descriptors, so output stays inside the VM and honors PTYs and redirection.\n- **Fills in libc expectations.** For example `fcntl(F_SETFL)` is serviced via `fd_fdstat_set_flags`, so flag changes that libc performs do not fail.\n- **Mirrors mounts as preopens.** The preopen table reflects the VM's guest path mappings, so mounted directories are visible to WASM path resolution exactly as they are to JS and to `node:fs`.\n- **Enforces read-only tiers.** `path_open` rejects create / truncate / write flags on read-only mounts while still allowing non-mutating opens (directory traversal, `O_DIRECTORY`), so read-only mounts stay read-only without breaking `find`, `ls`, and friends.\n- **Confines paths to their mount.** Targets are resolved beneath the specific preopen's root, so `..` segments cannot escape one mount into a sibling mount or a host path.\n\n```\nfd_read(0) -> kernel stdio bridge (not a host fd)\nfcntl(fd, F_SETFL) -> fd_fdstat_set_flags (libc flag changes succeed)\npath_open(\"/data/x\") -> resolved under the /data preopen root\npath_open(..O_CREAT) -> rejected on a read-only mount\npath_open(\"../../etc\")-> stays inside the mount; cannot escape\n```","src/content/docs/docs/architecture/posix-syscalls.mdx","afdc817a0338ca3a","docs/architecture/processes",{"id":386,"data":388,"body":391,"filePath":392,"digest":393,"deferredRender":16},{"title":389,"description":390,"skill":16},"Processes","Internals of the kernel process model: the virtual process table, how spawns are serviced, stdio bridging, PTYs, and how WASM sh and coreutils map onto it.","This page is an internals deep-dive on the kernel's **process model**: the data\nstructures and syscall paths behind every guest process. For the client-facing\nAPI (`exec`, `spawn`, `openShell`, lifecycle, the process tree), see\n[Processes & Shell](/docs/processes). For the surrounding component and trust\nmodel, see [Architecture](/docs/architecture).\n\nTwo invariants frame everything below:\n\n- **No real host process is ever spawned for guest work.** Every guest process is an entry in a kernel-owned virtual process table, not an OS process. Guest JavaScript runs in V8 isolates; guest commands like `sh` and coreutils run as WebAssembly. Neither is `node` or a host binary.\n- **Every process operation is a syscall into the kernel.** Spawning, waiting, signaling, reading stdout, and resizing a PTY all cross from the untrusted executor into the sidecar-owned kernel, which services them against virtualized resources.\n\n## The virtual process table\n\nEach VM owns one process table. It is the authority for what is \"running\"\ninside that VM; nothing in it corresponds to a host PID.\n\n- **Per-VM and isolated.** Two VMs have two independent tables. A PID in one VM is meaningless in another, and processes are never visible across the VM boundary.\n- **Holds every guest process,** not only the ones a client started explicitly. A `spawn` from the client, a child spawned by guest `node:child_process`, and the processes behind a shell pipeline are all table entries. This is why the system-wide views (`allProcesses`, `processTree`) can show more than what the client launched.\n- **Tracks lifecycle and lineage.** Each entry carries its PID, the command and arguments, parent PID (so the tree can be reconstructed), running/exited status, exit code once collected, and its attached stdio endpoints.\n- **Records a driver.** An entry knows which execution backend services it (for example a V8 isolate versus a WASM runtime). This is the `driver` field surfaced on `allProcesses`. Drivers differ in *how* the code runs; they share the same table, the same kernel-owned stdio, and the same boundary.\n\n\u003CNote>The process table is part of the kernel the sidecar owns. The executor never mutates it directly; it can only ask the kernel to create, wait on, or signal an entry. That request-only relationship is the sidecar-to-executor boundary applied to processes.\u003C/Note>\n\n## How a spawn is serviced\n\nA spawn, whether it originates from a client `spawn`/`exec` call or from guest\n`node:child_process`, follows one path through the kernel:\n\n1. **The request crosses into the kernel.** A client call arrives over the wire protocol; a guest call arrives as a syscall from the executor. Either way the kernel, not the caller, performs the work.\n2. **Permission check.** The kernel applies the VM's permission policy before doing anything. Process execution is denied by default and must be granted; the policy is trusted input, the guest making the request is not.\n3. **Resolve the program.** The command is resolved against the VM's virtual filesystem (PATH lookup over the VFS), not the host. The resolved program decides the driver: a JavaScript entrypoint runs in a V8 isolate; a `.wasm` program (including `sh` and coreutils) runs on the WASM runtime.\n4. **Allocate the table entry.** The kernel assigns a virtual PID, records the command, arguments, environment, working directory, and parent PID, and links stdio endpoints (see below).\n5. **Start execution.** The driver begins running the program. For a one-shot `exec` the kernel additionally collects stdout, stderr, and the exit code and returns them as the call's result; for `spawn` it leaves the process running and streams output via events.\n6. **Reap and record exit.** When the program finishes, the kernel records the exit code on the table entry and marks it exited, which is what a `wait`/`waitProcess` resolves against and what `processExit` reports.\n\nSignals (`stopProcess` / SIGTERM, `killProcess` / SIGKILL) are the same shape: a\nrequest into the kernel, which applies it to the virtualized process rather than\nto any host process.\n\n## Stdio bridging\n\nStandard streams are kernel-owned objects, not host file descriptors. Each\nprocess entry has stdin, stdout, and stderr endpoints that the kernel wires up\nwhen the entry is created.\n\n- **Capture vs. stream.** For `exec`, the kernel buffers stdout and stderr and hands them back when the process exits. For `spawn`, output is delivered incrementally as `processOutput` events tagged with the PID and the stream (`stdout`/`stderr`), and `processExit` signals completion.\n- **Writable stdin.** `writeProcessStdin` pushes bytes into the process's stdin endpoint; `closeProcessStdin` closes the write side so programs that read to EOF (like `cat`) can finish. None of this touches a real pipe on the host.\n- **Pipes between processes.** Shell pipelines (`a | b`) connect one process's stdout endpoint to the next process's stdin endpoint through kernel-owned pipes. The pipe is a virtual object in the kernel, so a pipeline behaves like Linux without any host IPC.\n\nBecause these endpoints are kernel objects, the same bridging works identically\nwhether the process is a V8 isolate or a WASM program; the driver writes to and\nreads from kernel stdio, not from anything host-provided.\n\n## PTYs and interactive shells\n\nAn interactive shell needs a terminal, not just piped stdio: line editing, job\ncontrol signals, and window size all depend on a PTY. The kernel provides\nvirtual PTY devices for this.\n\n- **A shell is a process plus a PTY.** `openShell` allocates a kernel PTY and starts a shell process attached to it, returning a `shellId`. The PTY is a virtualized terminal device, never a host `/dev/pts` entry.\n- **Bidirectional terminal I/O.** `writeShell` feeds keystrokes into the PTY master side; everything the shell and its children emit comes back as `shellData` events. This carries terminal control sequences, so full-screen TUIs behave correctly.\n- **Resize is a terminal operation.** `resizeShell` updates the PTY's window size (columns and rows), which the kernel propagates to the foreground process the way a real terminal resize would, so programs relying on `TIOCGWINSZ`-style sizing redraw correctly.\n- **Teardown.** `closeShell` tears down the PTY and the attached shell process. An open shell keeps the VM active, the same way an open PTY keeps a session alive on a real system.\n\n## WASM sh and coreutils on the process model\n\nThe shell and the standard commands behind process execution are not special\nhost helpers; they are ordinary guest processes that happen to be WebAssembly.\nFor the full WASM execution model see [WASM VM](/docs/architecture/posix-syscalls); here is how it\nmaps onto the process table specifically.\n\n- **They are normal table entries.** Running `sh`, `ls`, `cat`, etc. allocates virtual PIDs and table entries exactly like any other process, with the WASM driver recorded on each. A pipeline of coreutils is several entries linked by kernel pipes.\n- **POSIX process semantics are virtualized, not borrowed from the host.** Plain WASI has no process model (no `fork`/`exec`/`wait`). agentOS supplies those semantics through kernel-backed host imports, so a WASM program that spawns and waits on a child drives the *same* kernel process table that JS guests use. A coreutil spawning a subcommand is one table entry creating another.\n- **Same stdio, same PTY.** WASM processes read and write the kernel stdio endpoints described above, and a shell built from WASM `sh` attaches to a kernel PTY just like any interactive shell. The driver differs; the kernel-owned plumbing does not.\n\nThis is why the process model is uniform: whether an entry is a V8 isolate or a\nWASM binary, it lives in the same per-VM table, goes through the same\npermission-checked spawn path, and uses the same kernel-owned stdio and PTYs.\n\n## See also\n\n- [Processes & Shell](/docs/processes): the client API for running and managing processes.\n- [WASM VM](/docs/architecture/posix-syscalls): how WebAssembly guests get POSIX process, user, and network semantics.\n- [Architecture](/docs/architecture): components, the trust boundary, and the request lifecycle.\n- [Permissions](/docs/permissions): the policy the kernel checks on every spawn.","src/content/docs/docs/architecture/processes.mdx","000c86cdd9459fa0","docs/architecture/sessions-persistence",{"id":394,"data":396,"body":399,"filePath":400,"digest":401,"deferredRender":16},{"title":397,"description":398},"Sessions & Persistence","How agentOS, ACP, RivetKit actors, and durable session persistence fit together.","agentOS runs coding agents inside VMs and talks to them through the Agent\nCommunication Protocol (ACP). RivetKit wraps those VMs in durable actors, so a\nsession can survive actor sleep/wake even though the live VM and agent process\ndo not.\n\n## Layers\n\nagentOS session architecture has four layers:\n\n| Layer | Responsibility |\n| --- | --- |\n| RivetKit actor | Owns the public API and durable actor-local SQLite state. |\n| agentOS client | Thin facade used by the actor to create sessions, prompt agents, and call the sidecar. |\n| agentOS sidecar ACP extension | Launches ACP adapters inside the VM, speaks JSON-RPC, handles permissions, and owns resume orchestration. |\n| ACP adapter / agent | Runs inside the VM and speaks ACP over stdio. |\n\nThe actor is durable. The VM is disposable. The ACP agent process is live state\ninside the VM.\n\n## API Shape\n\nThe actor-facing session API is:\n\n- `createSession(agentType, options)`\n- `sendPrompt(sessionId, text)`\n- `closeSession(sessionId)`\n- `listPersistedSessions()`\n- `getSessionEvents(sessionId)`\n\n`sessionId` is the stable, client-facing id. If fallback resume creates a new\nlive ACP session id after wake, the actor keeps an internal\n`externalSessionId -> liveSessionId` remap. Clients keep using the original\n`sessionId`.\n\n## Create Flow\n\n1. The actor calls agentOS `createSession`.\n2. The sidecar starts the ACP adapter process inside the VM.\n3. The sidecar sends ACP `initialize`.\n4. The sidecar sends ACP `session/new`.\n5. The actor persists session metadata in `agent_os_sessions`.\n6. The actor starts capturing ACP `session/update` events for the session.\n\nPersisted session metadata includes:\n\n- `session_id`\n- `agent_type`\n- agent capabilities and agent info\n- create-time `cwd`\n- create-time `env`\n\nThe create-time `cwd` and `env` are used later so resumed sessions start with\nthe same working directory and environment they were created with.\n\n## Prompt Flow\n\n1. The actor receives `sendPrompt(sessionId, text)`.\n2. If the session is persisted but not live in the current VM, the actor lazily\n resumes it first.\n3. The actor writes a synthetic `user_prompt` event before forwarding the\n prompt.\n4. The actor forwards the prompt to the live ACP session id.\n5. The sidecar sends ACP `session/prompt`.\n6. Inbound ACP `session/update` events are captured into\n `agent_os_session_events`.\n\n`agent_os_session_events` is ordered per session. Sequence numbers are allocated\ninside the SQLite insert so concurrent prompt and stream captures cannot reuse\nthe same sequence number.\n\n## Sleep And Wake\n\nWhen a RivetKit actor sleeps:\n\n- the VM is destroyed\n- ACP adapter processes exit\n- the actor's in-memory `live_sessions` remap is lost\n- actor SQLite survives\n\nWhen the actor wakes:\n\n- a fresh VM boots\n- stable session ids still exist in `agent_os_sessions`\n- no ACP session is live yet\n- resume happens lazily on the next prompt\n\n## Resume Flow\n\nOn the first post-wake prompt for a persisted session:\n\n1. The actor reads `agent_os_sessions`.\n2. The actor reconstructs a Markdown transcript from\n `agent_os_session_events`.\n3. The actor writes the transcript to\n `/root/.agentos/threads/\u003CsessionId>.md`.\n4. The actor calls sidecar `resumeSession` with:\n - stable external `sessionId`\n - agent type\n - transcript path\n - persisted create-time `cwd`\n - persisted create-time `env`\n\nThe sidecar then chooses one of two resume paths.\n\n### Native Resume\n\nIf the ACP agent advertises `loadSession` or `resume`, the sidecar sends\n`session/load` or `session/resume`.\n\nWhen native resume succeeds:\n\n- the live ACP id is the stable external `sessionId`\n- the agent restores its own context\n- no transcript preamble is injected\n\nOpenCode uses this path when its own session store is still available in the\ndurable VM filesystem.\n\n### Transcript Fallback\n\nIf native resume is unsupported, or if native resume reports a normalized\n`unknown_session`, the sidecar falls back to a fresh session:\n\n1. The sidecar sends ACP `session/new`.\n2. The sidecar returns the new live ACP id to the actor.\n3. The actor stores `externalSessionId -> liveSessionId`.\n4. The sidecar prepends a one-shot preamble to the next prompt pointing at the\n transcript path.\n\nThe fallback is universal because it only requires the agent to read a file with\nits normal tools. It is lower fidelity than native resume because the transcript\nis pointed to, not automatically loaded into the agent's context window.\n\n## Unknown Session Normalization\n\nAdapters report missing sessions differently. The sidecar normalizes known\nmissing-session shapes into:\n\n```json\n{ \"error\": { \"data\": { \"kind\": \"unknown_session\" } } }\n```\n\nFor example, OpenCode currently reports a missing native session as:\n\n```json\n{ \"code\": -32603, \"data\": { \"details\": \"NotFoundError\" } }\n```\n\nThat shape is captured before normalization in tests, then normalized so the\nresume state machine can safely choose transcript fallback. Other internal\nerrors still propagate as failures.\n\n## Persistence\n\nDurable session state lives in actor SQLite:\n\n| Table | Purpose |\n| --- | --- |\n| `agent_os_sessions` | Stable session registry, agent type, capabilities, agent info, create-time `cwd`, and create-time `env`. |\n| `agent_os_session_events` | Append-only prompt and ACP event log keyed by the stable external `sessionId`. |\n\nThe transcript file is not canonical state. It is a disposable render of\n`agent_os_session_events`, rebuilt on demand during fallback resume.\n\n## What Is Durable\n\n| Data | Survives sleep/wake? | Notes |\n| --- | --- | --- |\n| Actor SQLite | Yes | Stores session registry, events, preview tokens, and other actor data. |\n| VM filesystem | Yes, when backed by the actor sqlite_vfs root | Used by agents and resume transcripts. |\n| Live ACP process | No | Recreated on wake. |\n| Actor in-memory vars | No | Includes the live ACP id remap. |\n| Client-facing `sessionId` | Yes | Stored in `agent_os_sessions`. |\n\n## Where To Look In Code\n\n- Sidecar ACP orchestration:\n `crates/agentos-sidecar/src/acp_extension.rs`\n- agentOS TypeScript client surface:\n `packages/core/src/agent-os.ts`\n- RivetKit actor session actions:\n `rivetkit-rust/packages/rivetkit-agent-os/src/actions/session.rs`\n- RivetKit persistence helpers:\n `rivetkit-rust/packages/rivetkit-agent-os/src/persistence.rs`","src/content/docs/docs/architecture/sessions-persistence.mdx","7a4569a76c301276","docs/custom-software/building-wasm",{"id":402,"data":404,"body":407,"filePath":408,"digest":409,"deferredRender":16},{"title":405,"description":406},"Building Binaries","Compile WASM command binaries for agentOS from source in the secure-exec registry.","WASM command packages ship **compiled `.wasm` binaries** in their `bin/` that run inside the VM as guest commands.

To use existing ones, install the published package (e.g. `@agentos-software/ripgrep`) and pass it to `software`. See [using the registry](#using-the-registry) below.\n\u003C/Note>\n\n## Where it lives\n\nCommand source and packages live under `registry/` in [secure-exec](https://github.com/rivet-dev/secure-exec/tree/main/registry):\n\n- **`registry/native/crates/commands/\u003Cname>/`**: the Rust source for each command — a cargo package named `cmd-\u003Cname>` that emits a `\u003Cname>` binary.\n- **`registry/native/c/`**: the C source for the C-built commands.\n- **`registry/software/\u003Cname>/`**: the npm package for each command set (`@agentos-software/\u003Cname>`). It exports a `{ packageDir }` descriptor pointing at the self-contained runtime directory assembled at `dist/package/`, and declares which binaries it ships in its `agentos-package.json` (`commands`, plus optional `aliases` and `stubs`).\n\n## Build\n\nEverything runs through `just` recipes at the secure-exec repo root:\n\n```bash\njust registry-native # compile ALL native wasm binaries (slow; once per checkout)\njust registry-native-cmd sh # recompile ONE command (cargo package cmd-sh)\njust registry-build # stage + assemble every registry package\njust registry-build ripgrep # ... or just one\njust registry-status # per-package state; --remote adds npm dist-tags\n```\n\nThe native build compiles each command for `wasm32-wasip1` with the pinned **nightly** toolchain from `rust-toolchain.toml` (the build vendors and patches `std` for WASI), optimizes with `wasm-opt`, and drops the binaries in `registry/native/target/wasm32-wasip1/release/commands/`. C-based commands (e.g. `sqlite3`, `unzip`, `wget`, `zip`) compile with a **wasi-sdk** clang toolchain via `make -C registry/native/c`.\n\nEach package's build then runs the **agentos-toolchain** lifecycle: `agentos-toolchain stage` copies the binaries listed in the package's `agentos-package.json` into its `bin/`, and `agentos-toolchain build` assembles the clean `dist/package/` runtime dir (the `{ packageDir }` target) with a `bin` map in its `package.json`.\n\n## Add a new command package\n\n1. Add the command source as `registry/native/crates/commands/\u003Cname>/` (cargo package `cmd-\u003Cname>`; Rust) or under `registry/native/c/` (C).\n2. Create `registry/software/\u003Cname>/` as an `@agentos-software/\u003Cname>` npm package that exports a `{ packageDir }` descriptor pointing at `dist/package/`.\n3. Declare the shipped binaries in its `agentos-package.json`: `{ \"commands\": [\"\u003Cname>\"] }` (plus `aliases`/`stubs` if needed).\n4. If it belongs in a meta-package (e.g. `common` or `build-essential`), add it there.\n5. Verify with `just registry-native-cmd \u003Cname> && just registry-build \u003Cname>` and `just registry-test`.\n\n## Let an agent build it\n\nThis is a mechanical, well-scoped task, so you can hand it to a coding agent. A prompt like:\n\n```text\nAdd a WASM command package for `\u003Ccommand>` to the secure-exec registry:\n- put the Rust source at registry/native/crates/commands/\u003Ccommand>/ as a cargo\n package named cmd-\u003Ccommand>,\n- create registry/software/\u003Ccommand>/ as an @agentos-software/\u003Ccommand> npm\n package that exports a { packageDir } descriptor and declares the command in\n its agentos-package.json,\nthen run `just registry-native-cmd \u003Ccommand> && just registry-build \u003Ccommand>`\nand `just registry-test`, and fix any failures.\n```\n\n## Using the registry\n\nInstall a published package and pass it to `software`.

The package's name, optional agent block, and any files/env it provides all live in an `agentos-package.json` at the root of that directory — the sidecar reads it when it mounts the package, so the client only forwards the directory. Pick the quickstart that matches what you're packaging.\n\n## Quickstart\n\n### WebAssembly\n\n\u003CSteps>\n\n1. **You have** C or Rust source for a command. (Most common commands already ship as `@agentos-software/*` packages you can use directly — compile only new or custom ones.)\n\n2. **Compile it** to WebAssembly — see [Building Binaries](/docs/custom-software/building-wasm). There's **no `pack` step**: WASM binaries are self-contained, so the compile output is already the package — a `bin/` of `\\0asm` files plus a `package.json` for the name/version:\n\n ```\n my-cmds/\n ├── package.json\n └── bin/\n ├── tool-a # \\0asm WebAssembly\n └── tool-b\n ```\n\n3. **Define it** — point `defineSoftware()` at that directory:\n\n \u003CCodeSnippet file=\"examples/software/quickstart-wasm/my-cmds.ts\" />\n\n4. **Use it** — pass it to a VM; the commands are on `$PATH`:\n\n \u003CCodeSnippet file=\"examples/software/quickstart-wasm/index.ts\" />\n\n\u003C/Steps>\n\n### Node.js\n\n\u003CSteps>\n\n1. **You have** a local project whose `package.json` `bin` names its commands:\n\n ```\n my-tool/\n ├── package.json # \"bin\": { \"my-tool\": \"cli.js\" }\n └── cli.js # #!/usr/bin/env node\n ```\n\n2. **Package it** — `pack` installs the full dependency closure into a self-contained package directory (a flat `node_modules` plus a `bin` map of real files):\n\n ```bash\n npx @rivet-dev/agentos-toolchain pack ./my-tool\n # writes ./my-tool-package/ (override the location with --out \u003Cdir>)\n # my-tool-package/\n # ├── package.json # \"bin\": { \"my-tool\": \"node_modules/my-tool/cli.js\" }\n # └── node_modules/ # flat, self-contained closure\n ```\n\n Commands come from the package's `package.json` `bin` map — **real files, no symlinks** — so the result ships cleanly as an npm dependency. (The runtime makes the `/opt/agentos/bin` symlinks itself when it mounts the package.) A native `.node` addon is an error (it can't run in V8); re-run with `--prune-native` to drop unreachable ones.\n\n3. **Define it** — point `defineSoftware()` at the packaged directory:\n\n \u003CCodeSnippet file=\"examples/software/quickstart-node/my-tool.ts\" />\n\n4. **Use it** — pass it to a VM; `my-tool` is now on `$PATH`:\n\n \u003CCodeSnippet file=\"examples/software/quickstart-node/index.ts\" />\n\n\u003C/Steps>\n\n### Agent\n\nAn agent is a Node.js or WASM package (packaged exactly as above) whose `agentos-package.json` carries an **`agent` block** naming a `bin/` command that speaks ACP over stdio.\n\n\u003CSteps>\n\n1. **You have** an npm package with a `bin/` command that speaks ACP over stdio.\n\n2. **Package it** — same `pack` as Node.js, with `--agent` naming the ACP entrypoint. That writes the `agent` block into the package's `agentos-package.json`:\n\n ```bash\n npx @rivet-dev/agentos-toolchain pack @scope/my-agent --out ./packages --agent my-agent-acp\n # → ./packages/my-agent/current (its agentos-package.json now has the agent block)\n ```\n\n3. **Define it** — point `defineSoftware()` at the packaged directory; the agent block is already in its `agentos-package.json`:\n\n \u003CCodeSnippet file=\"examples/software/quickstart-agent/my-agent.ts\" />\n\n4. **Use it** — `createSession()` launches the agent by spawning its `acpEntrypoint`:\n\n \u003CCodeSnippet file=\"examples/software/quickstart-agent/index.ts\" />\n\n\u003C/Steps>\n\n## Reference\n\n### The descriptor\n\nA software entry is just a pointer to the packaged directory:\n\n```ts\ndefineSoftware({\n packageDir: string, // absolute host path to the self-contained package directory\n})\n```\n\n`packageDir` must contain **only the package** — a `package.json` with a `bin` map, the runtime\nfiles (`bin/`, a flat `node_modules`), and an `agentos-package.json`. It is mounted read-only, so\n**don't point it at a source root**: that drags `src/`, dev `node_modules/`, `tsconfig`, and build\ncaches into the VM. Point it at a clean build output — `pack` and the WASM assemble step both emit\none.\n\n\u003CNote>\n`pack` already emits a clean directory. For a package you build by hand (e.g. compiled WASM),\nassemble a `dist/package/` holding just `package.json` + `bin/` and point `packageDir` there —\nnever at the workspace root:\n\n```ts\n// dist/package/ ← { package.json (name, version, bin), bin/\u003Ccmd>…, agentos-package.json }\nconst packageDir = resolve(import.meta.dirname, \"dist/package\");\nexport default defineSoftware({ packageDir });\n```\n\u003C/Note>\n\n### `agentos-package.json`\n\nThe package's name, optional agent block, and any files/env it provides live in an\n`agentos-package.json` at the root of `packageDir`. The sidecar reads it when it mounts the\npackage, so this metadata never travels on the wire. For command/WASM packages it is **generated**\nfor you (name from `package.json`); for agents you author the `agent` block (or\n`agentos-toolchain pack --agent \u003Ccmd>` writes it).\n\n```jsonc\n{\n \"name\": \"my-agent\", // → /opt/agentos/\u003Cname>\n \"agent\": { // optional — also exposes an agent session\n \"acpEntrypoint\": \"my-agent-acp\", // bin/ command that speaks ACP over stdio\n \"env\": { }, // static env for the adapter\n \"launchArgs\": [],\n \"snapshot\": false // SDK snapshot optimization\n },\n \"provides\": { // optional — files + env the package contributes\n \"env\": { \"EXAMPLE_HOME\": \"/opt/agentos/my-agent\" },\n \"files\": [{ \"source\": \"etc/example.conf\", \"target\": \"/etc/example.conf\" }]\n }\n}\n```\n\n- **`name`** — the package name; commands and the package mount under `/opt/agentos/\u003Cname>`.\n- **`agent.acpEntrypoint`** — the `bin/` command spawned to start a session; speaks ACP over stdio.\n- **`agent.env`** — static env vars for the adapter, merged under the user env. Every command is on `$PATH`, so point at one directly, e.g. `{ \"PI_ACP_PI_COMMAND\": \"/opt/agentos/bin/pi\" }` so `pi-acp` can spawn the `pi` CLI.\n- **`agent.launchArgs`** — extra CLI args prepended when launching the adapter.\n- **`agent.snapshot`** (default `false`) — load the SDK [once per sidecar](#sdk-snapshotting--snapshot-safety) via a shared V8 heap snapshot instead of per session. Falls back to per-session loading if the SDK isn't snapshot-safe, so it only affects startup latency.\n- **`provides.env`** — env vars merged into the VM's base environment (existing values win — a package never clobbers the user env).\n- **`provides.files`** — read-only files overlaid into the VM filesystem. Each `{ source, target }` maps a path **inside the package** to an **absolute VM path**; the sidecar mounts them as zero-copy read-only lower layers (a guest write copies-up, never touching the host). A missing `source` is a fatal packaging error.\n\n## Advanced\n\n### Meta-packages\n\nA software entry may be an **array** of descriptors, so one package can bundle several. Pass arrays directly to `software`:\n\n```ts\nconst vm = agentOS({\n software: [pi, buildEssential /* = [coreutils, make, git, curl] */],\n});\n```\n\n### SDK snapshotting & snapshot-safety\n\nA V8 heap snapshot freezes the heap *after* the SDK's modules are evaluated, then seeds each new session's isolate from it. This works only if the SDK's **module-init** code (everything that runs at `import`/`require` time) doesn't:\n\n- Create **native handles** — load a `.node` addon, instantiate WebAssembly, or produce a V8 `External`/`Foreign` at top level.\n- Open a **file descriptor, socket, timer, or worker**, or leave a **pending promise**.\n- Bake in **non-deterministic or per-session state** — `process.env`, cwd, `Date.now()`, `Math.random()`, a UUID.\n\nDefer all of the above behind functions or lazy `import()` that run per session. Leave `agent.snapshot: false` for any SDK that can't — the agent still runs, just without the speedup.\n\n## Next steps\n\n- [Custom Agents](/docs/agents/custom): the agent-focused guide.\n- [Building Binaries](/docs/custom-software/building-wasm): compile WASM commands and use the registry.\n- [Packages & command resolution](/docs/architecture/packages-and-command-resolution): how packages mount and resolve.\n- [Request Software](https://github.com/rivet-dev/agentos/issues/new/choose): ask for a package you need.","src/content/docs/docs/custom-software/definition.mdx","dcd2bb664473b0e4","cookbooks/agent-to-agent",{"id":418,"data":420,"body":423,"digest":424,"rendered":425},{"title":421,"description":422},"Agent to Agent","Bridge two isolated agent VMs: a writer agent calls a reviewer agent through a binding.","\nRun two agents in separate isolated VMs and let one delegate to the other.

(Not part of the shipped package — npm can't carry symlinks.) |\n| `libexec/` | Helpers invoked by other programs, never on `$PATH` (e.g. a multicall blob). |\n| `node_modules/`, `lib/` | Non-executable payload — bundled deps and assets. |\n| `share/` | FHS data — `share/man/man\u003Cn>/*`, etc. |\n| `current` | Symlink `→ \u003Cversion>`; switching versions is one atomic rename. |\n\n```jsonc\n// package.json — commands come from \"bin\"; an agent's ACP entrypoint is just one of them\n{ \"name\": \"pi\", \"version\": \"0.60.0\", \"bin\": { \"pi-acp\": \"dist/acp.js\" } }\n```\n\nA directory is a **valid package** when:\n\n- **Commands come from `package.json` `bin`** (command → a real entry file), and each entry\n **dispatches by header** — a magic number or `#!` shebang, no `.wasm`/`.js` extension or\n `runtime`/`type` field; a headerless entry is `ENOEXEC`. The package ships **no symlinks**\n (npm-safe); the runtime builds the `bin/` farm under `/opt/agentos` itself.\n- **Aliases are symlinks** in the projected `bin/` farm — several names for one program (or a\n multicall blob); `argv[0]` is the invoked name.\n- **It is self-contained** — every import/require/asset resolves inside the package; nothing\n comes from a host `node_modules`, pnpm store, or workspace at runtime\n ([packaging](/docs/custom-software/definition) flattens/bundles deps in).\n- **Minimal metadata** — `package.json` carries only the command set (`bin`) and `version`; there\n is no command list beyond `bin`, no permission tiers (the [VM policy](#confinement--trust)\n governs every command), and no dependency list. A small **`agentos-package.json`** alongside it\n holds the agentOS-specific fields the sidecar reads when it mounts the package — the `name`, an\n optional `agent` block, and any `provides` (files/env). The client never carries this on the\n wire; it forwards only the package directory.\n\n## Linking\n\nLinking is creating the `bin/` symlinks in a `$PATH` directory. agentOS follows Homebrew:\n`/opt/agentos/\u003Cname>` is the cellar, and every command is symlinked into one managed prefix,\n**`/opt/agentos/bin`**, which is on `$PATH`. The standard dirs (`/usr/bin`, `/usr/local/bin`,\n`/bin`) stay ordinary writable Linux dirs — agentOS never writes to them.\n\n\u003Csvg viewBox=\"0 0 760 150\" xmlns=\"http://www.w3.org/2000/svg\" role=\"img\" aria-label=\"PATH search order, left to right, first match wins\" style=\"width:100%;max-width:720px;height:auto;font-family:system-ui,sans-serif\">\n \u003Cdefs>\n \u003Cmarker id=\"pcr-ah2\" viewBox=\"0 0 10 10\" refX=\"8.5\" refY=\"5\" markerWidth=\"7\" markerHeight=\"7\" orient=\"auto\">\n \u003Cpath d=\"M0 0 L10 5 L0 10 z\" fill=\"#94a3b8\"/>\n \u003C/marker>\n \u003C/defs>\n \u003Ctext x=\"16\" y=\"20\" font-size=\"12\" fill=\"#0f172a\">Searched left → right — first match wins (left shadows right)\u003C/text>\n \u003Cline x1=\"16\" y1=\"33\" x2=\"744\" y2=\"33\" stroke=\"#cbd5e1\" stroke-width=\"1.2\" marker-end=\"url(#pcr-ah2)\"/>\n \u003Crect x=\"16\" y=\"50\" width=\"99\" height=\"44\" rx=\"6\" fill=\"#f8fafc\" stroke=\"#cbd5e1\" stroke-width=\"1.3\"/>\n \u003Ctext x=\"65.5\" y=\"76\" text-anchor=\"middle\" font-size=\"9\" font-family=\"ui-monospace,monospace\" fill=\"#334155\">/usr/local/sbin\u003C/text>\n \u003Crect x=\"121\" y=\"50\" width=\"99\" height=\"44\" rx=\"6\" fill=\"#f8fafc\" stroke=\"#cbd5e1\" stroke-width=\"1.3\"/>\n \u003Ctext x=\"170.5\" y=\"76\" text-anchor=\"middle\" font-size=\"9\" font-family=\"ui-monospace,monospace\" fill=\"#334155\">/usr/local/bin\u003C/text>\n \u003Crect x=\"226\" y=\"50\" width=\"99\" height=\"44\" rx=\"6\" fill=\"#eef2ff\" stroke=\"#6366f1\" stroke-width=\"2\"/>\n \u003Ctext x=\"275.5\" y=\"76\" text-anchor=\"middle\" font-size=\"9\" font-family=\"ui-monospace,monospace\" fill=\"#3730a3\">/opt/agentos/bin\u003C/text>\n \u003Crect x=\"331\" y=\"50\" width=\"99\" height=\"44\" rx=\"6\" fill=\"#f8fafc\" stroke=\"#cbd5e1\" stroke-width=\"1.3\"/>\n \u003Ctext x=\"380.5\" y=\"76\" text-anchor=\"middle\" font-size=\"9\" font-family=\"ui-monospace,monospace\" fill=\"#334155\">/usr/sbin\u003C/text>\n \u003Crect x=\"436\" y=\"50\" width=\"99\" height=\"44\" rx=\"6\" fill=\"#f8fafc\" stroke=\"#cbd5e1\" stroke-width=\"1.3\"/>\n \u003Ctext x=\"485.5\" y=\"76\" text-anchor=\"middle\" font-size=\"9\" font-family=\"ui-monospace,monospace\" fill=\"#334155\">/usr/bin\u003C/text>\n \u003Crect x=\"541\" y=\"50\" width=\"99\" height=\"44\" rx=\"6\" fill=\"#f8fafc\" stroke=\"#cbd5e1\" stroke-width=\"1.3\"/>\n \u003Ctext x=\"590.5\" y=\"76\" text-anchor=\"middle\" font-size=\"9\" font-family=\"ui-monospace,monospace\" fill=\"#334155\">/sbin\u003C/text>\n \u003Crect x=\"646\" y=\"50\" width=\"99\" height=\"44\" rx=\"6\" fill=\"#f8fafc\" stroke=\"#cbd5e1\" stroke-width=\"1.3\"/>\n \u003Ctext x=\"695.5\" y=\"76\" text-anchor=\"middle\" font-size=\"9\" font-family=\"ui-monospace,monospace\" fill=\"#334155\">/bin\u003C/text>\n \u003Ctext x=\"16\" y=\"130\" font-size=\"11\" fill=\"#475569\">agentOS links into \u003Ctspan font-family=\"ui-monospace,monospace\" fill=\"#4338ca\">/opt/agentos/bin\u003C/tspan>; the rest are ordinary writable Linux dirs — drop a binary in \u003Ctspan font-family=\"ui-monospace,monospace\" fill=\"#4338ca\">/usr/local/bin\u003C/tspan> to shadow an agentOS tool.\u003C/text>\n\u003C/svg>\n\n| Software | Stored | Linked into |\n|---|---|---|\n| Base, mounted, and runtime-installed agentOS software | `/opt/agentos/\u003Cpkg>/\u003Cver>` (or the mount) | `/opt/agentos/bin` |\n| The user's own files | wherever they put them | `/usr/local/bin`, `/usr/bin`, … (normal) |\n\n- **Base & mounts** link into `/opt/agentos/bin` in a **read-only layer** projected from the\n host and shared across VMs — the symlinks are real but cost nothing per boot.

The command's **name plays no part** — `python3`, `node`,\nand `pi` are runtimes only by virtue of their files' headers.\n\n| Header | Result |\n|---|---|\n| `#!` at bytes 0–1 (`binfmt_script`) | the interpreter named on the line |\n| `\\0asm` (`00 61 73 6d`) | WebAssembly runtime |\n| `\\x7fELF` / Mach-O / PE | **`ENOEXEC`** — foreign binary format, no native-arch handler |\n| anything else | `ENOEXEC` (no implicit `/bin/sh` fallback here) |\n\nShebang handling matches `binfmt_script`:\n\n- The interpreter path is **literal and absolute** — not `$PATH`-searched. `#!/usr/bin/env node`\n works only because `/usr/bin/env` looks up its argument.\n- At most **one** argument follows, **not** whitespace-split (`#!/usr/bin/env node --flag` passes\n `node --flag` as a single arg).\n- The header read is bounded to a fixed buffer (`BINPRM_BUF_SIZE`); a longer line truncates.\n Interpreter chaining is depth-bounded (`ELOOP`); a missing interpreter is **`ENOENT`**, not `ENOEXEC`.\n\n\u003CNote>\n**Shell fallback.** On `ENOEXEC`, a POSIX shell re-runs a headerless script via `/bin/sh`. That\nretry lives in the shell ([agentos-shell](/docs/architecture/processes)), not the dispatcher,\nwhich stays strictly `binfmt`-faithful.\n\u003C/Note>\n\n### Multicall (busybox-style)\n\n`bin/ls → ../libexec/coreutils` resolves at open to the shared `coreutils` blob. `argv[0]` is\nthe caller's value **verbatim** (`\"ls\"`) — never derived from the symlink — and the blob selects\nits applet with `basename(argv[0])`, like busybox. Always invoke via the `bin/` name; calling the\nblob by its own path yields an `argv[0]` that selects no applet.\n\n## Command resolution\n\nA `$PATH` walk over the [VFS](/docs/architecture/filesystem), full Linux semantics:\n\n- A name **containing `/`** bypasses `$PATH` and resolves directly (relative to cwd, or absolute).\n- Otherwise each `:`-separated dir is searched in order; the first **executable** regular file\n wins (execute bit required — a non-executable match yields `EACCES`). Left shadows right.\n- An **empty `$PATH` element** (leading/trailing/`::`) means the **current working directory** —\n the POSIX footgun, kept for fidelity.\n- Matches are real VFS files/symlinks — `ls -l`-able, `stat`-able, removable, replaceable. The\n filesystem is authoritative; there is no resolution cache to grow stale.\n\n## The `agentos-software` CLI\n\n```\nagentos-software link \u003Cpath>\n```\n\n- `\u003Cpath>` is a package directory or a node module directory (its `package.json` `bin` map is\n the command list).\n- It brokers a request to the sidecar, which owns the filesystem; the CLI has no privilege of\n its own.\n- Linked names are validated (no `/`, `..`, control chars, overlong names), and for a\n guest-supplied package each symlink target must resolve inside the package root.\n\n## Confinement & trust\n\nEvery process runs under the VM's single [permission policy](/docs/security-model) — like a\nLinux process running with its user/namespace/container privileges, not privileges declared by\nthe binary. A package cannot grant itself permissions. The [trust boundary](/docs/security-model)\nis the sidecar (trusted) vs. the guest (untrusted):\n\n- **Linking changes discoverability, not privilege** — the policy is enforced at spawn,\n regardless of how a command was found.\n- **Shadowing is allowed, Linux-style** — a guest may drop a `node`/`ls` into a writable `$PATH`\n dir; trusted in-VM components defend by invoking tools via **absolute paths** (or a `$PATH`\n that excludes guest-writable dirs). The shadowing binary still runs only under the VM policy.\n- **Guest env is sanitized** like a privileged exec — `LD_*`, `DYLD_*`, `NODE_OPTIONS`, `PATH`,\n `BASH_ENV`, `*PRELOAD` are stripped, as glibc does under `AT_SECURE`.\n- **Trusted vs. guest packages** — symlink-escape checks apply only to guest-writable runtime packages.\n- **Bounded** — the runtime link count is bounded; it warns on approach and fails with a typed\n error naming the limit (see [Limits & Observability](/docs/architecture/limits-and-observability)).\n\n## See also\n\n- [Software Definition](/docs/custom-software/definition) — the host API that produces these packages.\n- [Processes](/docs/architecture/processes) — the JavaScript, WebAssembly, and Python runtimes.\n- [Filesystem](/docs/architecture/filesystem) — the VFS, layers, and persistence.\n- [Security Model](/docs/security-model) — the trust boundary and VM permission policy.","src/content/docs/docs/architecture/packages-and-command-resolution.mdx","de3879554bd53da6","docs/custom-software/publishing",{"id":886,"data":888,"body":891,"filePath":892,"digest":893,"deferredRender":16},{"title":889,"description":890},"Publishing Packages","Build, publish, and consume agentOS packages — locally, from npm, or from your own repo.","agentOS packages — WASM command sets and packed JS agents alike — go through one lifecycle, owned by the **`@rivet-dev/agentos-toolchain`** CLI. This page covers the full flow: building a package, publishing it to npm, and wiring a consumer at either a published version or a local checkout.\n\n## The lifecycle\n\nEvery package is an npm package whose default export points at a self-contained runtime dir (`dist/package/`) that the sidecar projects under `/opt/agentos/\u003Cname>/\u003Cversion>`. The toolchain provides four subcommands:\n\n| Command | What it does |\n|---|---|\n| `stage --commands-dir \u003Cdir>` | Populate `bin/` from a directory of compiled binaries, per the `commands` / `aliases` / `stubs` lists in the package's `agentos-package.json`. |\n| `build` | Assemble `dist/package/` from `bin/` (+ optional `share/`): a clean `package.json` with a `bin` command map, plus the runtime `agentos-package.json`. |\n| `pack` | Build a self-contained node-closure package from an npm package or local dir (JS agents; validates headers, rejects native addons). |\n| `publish` | Publish the built package to npm. Dist-tag is **`dev` by default**; the `latest` pointer only moves with an explicit `--latest`. |\n\n## Building\n\nIn the secure-exec registry, the `just` recipes drive the toolchain (see [Building Binaries](/docs/custom-software/building-wasm)):\n\n```bash\njust registry-native # compile the native wasm binaries (once per checkout)\njust registry-build # stage + assemble every registry package\njust registry-build coreutils # ... or one package\njust registry-status # inspect: version, staged bin/, assembled dist\n```\n\n## Publishing\n\nRegistry packages **version independently** — each package carries its own semver in its `package.json`. Bump and commit the version, then:\n\n```bash\njust registry-publish coreutils # publish under dist-tag `dev`\njust registry-publish coreutils my-branch # ... under a custom tag\njust registry-publish coreutils latest # DELIBERATE release: moves `latest`\njust registry-publish-all # every built software package, tag `dev`\n```\n\nConsumers installing `@agentos-software/\u003Cname>` with no tag resolve `latest`, so `latest` is reserved for deliberate releases — a dev publish can never clobber what users install.\n\n## Consuming published packages\n\nIn agent-os, the `@agentos-software/*` packages are pinned **per-package** in the workspace catalog. Manage the pins with the `just` recipes (never hand-edit them):\n\n```bash\njust agentos-pkgs-status # current mode + pinned versions\njust agentos-pkgs-set-version coreutils 0.3.1 # pin one package\njust agentos-pkgs-update # re-pin all from the `latest` dist-tag\njust agentos-pkgs-update dev # ... or from another tag\n```\n\n## Local development\n\nBoth sides consume local builds by default:\n\n- **secure-exec**: the registry packages are pnpm workspace members, so its tests and examples always resolve the in-repo builds — publish nothing while iterating.\n- **agent-os**: the **committed** dependency state is file-based — `link:`/`path` deps into the sibling `../secure-exec` checkout, with a committed `secure-exec.ref` sha that CI materializes the sibling at. Keep a sibling checkout, build its registry packages (`just registry-native` + `just registry-build` there), and everything resolves locally with no mode flipping. Advance the dependency with `just secure-exec-bump [sha]`.\n\nPublished-version pins exist only transiently inside agent-os publish workflows (`release-swap`): previews auto-cut a secure-exec preview at the committed ref, releases pin a real secure-exec release — and the swap is never committed.\n\n## Publishing from your own repo\n\nThe toolchain is not registry-specific — any repo can produce and publish agentOS packages with `npx @rivet-dev/agentos-toolchain`:\n\n```bash\n# a package dir with package.json + agentos-package.json + your compiled binaries\nnpx @rivet-dev/agentos-toolchain stage --commands-dir ./build/wasm\nnpx @rivet-dev/agentos-toolchain build\nnpx @rivet-dev/agentos-toolchain publish --tag dev # or --latest for a release\n```\n\nFor a JS agent, `pack` replaces `stage`/`build`:\n\n```bash\nnpx @rivet-dev/agentos-toolchain pack . --out dist/package --agent my-acp-entrypoint\n```\n\nThe published package is a plain npm dependency — consumers import its descriptor and pass it to `software` exactly like the registry packages.

You can swap the implementation without changing the agent's behavior.\n- **No credentials in the VM.** The binding executes on the server, so it can access other agents directly without exposing connection details.\n- **Composable.** Chain any number of agents by adding more bindings. Each binding is a self-contained bridge to another agent.\n\n## Recommendations\n\n- Each agent has its own isolated VM and filesystem (they share no filesystem). Pass file contents through the binding input, then use `writeFile` in the binding to land them in the other VM.\n- Use [Workflows](/docs/workflows) to make multi-agent pipelines durable across restarts.","src/content/docs/docs/agent-to-agent.mdx","166030497fa3e2b1","docs/approvals",{"id":20,"data":22,"body":25,"filePath":26,"digest":27,"deferredRender":16},{"title":23,"description":24,"skill":16},"Approvals","Approve or deny agent tool use with human-in-the-loop or auto-approve patterns.","When an agent wants to use a tool (write a file, run a command, etc.), it asks for permission.

The server runs the **sidecar**, the trusted core that hosts every VM: it owns each VM's kernel and brokers every guest syscall the agent makes (filesystem, processes, network, permissions) before carrying it out. Each VM is a fully isolated world, so agents are isolated from one another and from your host.\n\n### Your app (the client)\n\n- **Trusted caller.** Your app drives agentOS. It creates VMs, opens sessions, sends prompts, and reads results back.\n- **Never runs guest code.** The agent and any code it generates run in the VM, not in your app's process.\n- **Available everywhere.** There is a TypeScript client and a Rust client, and the same VM is reachable from a Node script, a browser/React app, or a separate backend.\n- **Owns the configuration.** Everything you send (VM setup, permission policy, resource limits, mounts) is trusted input. See the [Security Model](/docs/security-model) for why your configuration is not an attack surface.\n\n### Your server (the sidecar)\n\n- **The trusted core.** The sidecar is the part of the system that owns everything: the kernel, the virtual filesystem, the process and socket tables, pipes, PTYs, the permission policy, and DNS.\n- **The enforcement point.** Every request the VM makes is serviced here. The sidecar decides what is allowed before carrying it out.\n- **Hosts every VM.** A single sidecar manages many VMs side by side, each with its own kernel, filesystem, and process table, so every agent runs in its own isolated world. A crash or runaway in one VM never affects another.\n\n### The VM\n\n- **A fully virtualized Linux environment.** Each VM has its own filesystem, process table, and network policy. Two VMs share nothing.\n- **The unit of isolation.** Put one tenant or one task per VM to control the blast radius. A crash or runaway in one VM never affects another.\n- **Where guest code lives.** The agent, the shell, npm packages, and any generated code all run inside the VM, behind the kernel's boundary.\n\n## Anatomy of a Linux VM\n\nInside every VM there are two halves. The **kernel** is the trusted core that owns all the resources and rules. The **executor** is where untrusted guest code actually runs.

It is genuinely fast, and it presents normal Node.js semantics. See [JavaScript Runtime](/docs/nodejs-runtime).\n- **WASM alongside it.** The shell (`sh`) and the coreutils behind process execution ship as WebAssembly modules, and you can run your own WASM too. See [POSIX Syscalls](/docs/architecture/posix-syscalls) and the [Compiler Toolchain](/docs/architecture/compiler-toolchain).\n- **Native binaries.** Tools mounted into the VM run inside the same boundary as everything else.\n- **No host fallthrough.** The executor holds no capability of its own.

The sidecar resolves omitted top-level scopes to `allow`; pass explicit denies or rule sets when the workload needs restriction. On top of that, [approvals](/docs/approvals) are about an agent asking before it uses a tool.\n- **Human-in-the-loop or automatic.** Subscribe to `permissionRequest` and respond per request, or use a server-side hook to decide without a client round-trip.\n- **Blocks until answered.** If neither your hook nor your client responds, the agent waits rather than proceeding.\n\n## Orchestration (Rivet Actors)\n\nThe `agentOS()` actor (from `@rivet-dev/agentos`) wraps the raw VM in a [Rivet Actor](/docs/core), which adds durable state, scheduling, and orchestration.

You reach a specific VM by name (`vm.getOrCreate(\"my-agent\")`).\n- **Stateful by default.** Unlike the bare core package, the actor keeps its filesystem and sessions persistent and handles distributed state for you.\n- **The portable runtime.** Actors give you a consistent way to run `agentOS()` on any infrastructure, with persistence, networking, and orchestration built in.\n\n### Cron\n\n- **Recurring work.** Schedule a shell command or an agent session on a cron expression.\n- **Overlap control.** Choose what happens when a run is still going when the next is due (`allow`, `skip`, or `queue`).\n- **Observable.** Stream `cronEvent`s to watch executions. See [Cron Jobs](/docs/cron).\n\n### Workflows\n\n- **Durable multi-step tasks.** A workflow is the actor's `run` handler wrapped in `workflow()`, where each `ctx.step()` is recorded, retried, and resumed independently.\n- **Crash-proof.** If the process dies mid-run, replay skips completed steps and continues where it left off.\n- **Composable.** The output of one step feeds the next: clone a repo, let an agent fix a bug, run the tests. See [Workflow Automation](/docs/workflows).\n\n### Persistence & sleep/wake\n\n- **Sleeps when idle.** After a grace period (15 minutes by default) with no activity, the VM sleeps to free resources.\n- **Wakes on demand.** It wakes automatically when a client connects or a cron job fires.\n- **What survives.** The `/home/agentos` filesystem, session records, transcripts, preview tokens, and cron definitions all persist. In-memory kernel state (running processes, open shells) does not. See [Persistence & Sleep](/docs/persistence).\n\n## Going deeper\n\nThis page is the map. Each subsystem has its own detailed page in the Advanced architecture section:\n\n- **[Agent Sessions](/docs/architecture/agent-sessions)**: how a session is bound to a VM, and how prompts and events flow end to end.\n- **[Processes](/docs/architecture/processes)**: the virtual process table, `exec()` / `run()`, child processes, and PTYs.\n- **[Filesystem](/docs/architecture/filesystem)**: the per-VM virtual filesystem, overlays, and host-backed mounts.\n- **[Networking](/docs/architecture/networking)**: the virtual socket table, DNS, the allowlist, and guest `fetch()`.\n- **[POSIX Syscalls](/docs/architecture/posix-syscalls)**: how WebAssembly guests behave like normal POSIX programs on top of the kernel.\n- **[Compiler Toolchain](/docs/architecture/compiler-toolchain)**: how the shell and coreutils are compiled to WebAssembly and mounted into the VM.\n- **[System Prompt](/docs/system-prompt)**: the context agentOS injects into every agent session.\n- **[Persistence & Sleep](/docs/persistence)**: what survives sleep/wake, and how VMs sleep and wake.\n\nFor the trust model and what counts as a sandbox escape, see the [Security Model](/docs/security-model).","src/content/docs/docs/architecture.mdx","3dbb5ae809a2d009","docs/benchmarks",{"id":44,"data":46,"body":49,"filePath":50,"digest":51,"deferredRender":16},{"title":47,"description":48,"skill":16},"Benchmarks","Performance benchmarks comparing agentOS to traditional sandbox providers.","These are the benchmark figures shown on the agentOS marketing page. All numbers are computed from the same data source used by the marketing page. For independent sandbox comparison data, see the [ComputeSDK benchmarks](https://www.computesdk.com/benchmarks/).\n\n## Cold start\n\nTime from requesting an execution to first code running. Measured using the sleep workload (a minimal VM running an idle Node.js process). Sandbox baseline: **E2B**, the fastest mainstream sandbox provider as of March 30, 2026. See [ComputeSDK benchmarks](https://www.computesdk.com/benchmarks/) for independent sandbox comparison data.\n\n| Metric | agentOS | Fastest sandbox (E2B) |\n|---|--:|--:|\n| Cold start p50 | 4.8 ms | 440 ms |\n| Cold start p95 | 5.6 ms | 950 ms |\n| Cold start p99 | 6.1 ms | 3,150 ms |\n\n## Memory per instance\n\nMeasured via staircase benchmarking:\n\n1. **Warmup.** A throwaway VM is created, started, and destroyed before measurement begins. This pays one-time costs (module cache, JIT compilation) that are amortized away in any real deployment where the host process is long-lived.\n2. **Baseline.** GC is forced twice (`--expose-gc`), then RSS is sampled across the entire process tree by reading `/proc/[pid]/statm` for the host process and all descendants. This captures child processes (e.g. V8 isolates running as separate processes) that `process.memoryUsage().rss` would miss.\n3. **Staircase.** VMs are added one at a time. After each VM starts and settles, GC is forced and RSS is sampled again. The delta from the previous sample is the incremental cost of that VM.\n4. **Average.** The per-VM cost is the mean of all step deltas.\n5. **Teardown.** All VMs are disposed and the reclaimed RSS is recorded.\n\nRSS is a process-wide metric that includes thread stacks and OS-mapped pages beyond the VM itself, so the reported figure is an upper bound on the true per-VM cost.\n\nSandbox baseline: **Daytona**, the cheapest mainstream sandbox provider as of March 30, 2026.

All on-demand pricing.\n\n## Reproducing\n\nagentOS benchmarks live in the [agent-os repository](https://github.com/rivet-dev/agentos) under `scripts/benchmarks/`.\n\n### Prerequisites\n\n- Node.js (see `.nvmrc`) and `pnpm`, with dependencies installed: `pnpm install`\n- A Rust toolchain (`cargo`) — the benchmarks build and run the native release sidecar\n- A reasonably **idle machine**: cold-start latency tails are sensitive to background CPU and GC jitter\n\n### Run everything\n\nFrom the repository root:\n\n```sh\n./scripts/benchmarks/run-benchmarks.sh\n```\n\nThe script builds the TypeScript packages and an **optimized (release) sidecar**, points the SDK at it via `AGENT_OS_SIDECAR_BIN`, and writes one JSON result per benchmark to `scripts/benchmarks/results/`:\n\n| Result file | Feeds marketing input |\n|---|---|\n| `coldstart-sleep.json` | `COLDSTART_P50/P95/P99_MS` |\n| `memory-sleep.json` | `MEMORY_SHELL_MB` (`result.avgPerVmRssBytes / 1024²`) |\n| `memory-pi-session.json` | `MEMORY_AGENT_MB` (`result.avgPerVmRssBytes / 1024²`) |\n\nCopy those numbers into `website/src/data/bench.ts`; every figure and multiplier on this page recomputes from them.\n\n### Run a single benchmark\n\nEach benchmark is a standalone `tsx` entrypoint. Build first (`pnpm build` and `cargo build --release -p agent-os-sidecar`), then:\n\n```sh\nexport AGENT_OS_SIDECAR_BIN=\"$PWD/target/release/agent-os-sidecar\"\n\n# Cold start (sleep workload)\npnpm exec tsx scripts/benchmarks/coldstart.bench.ts --workload=sleep --iterations=2000\n\n# Memory — simple shell command\npnpm exec tsx --expose-gc scripts/benchmarks/memory.bench.ts --workload=sleep --count=20\n\n# Memory — full coding agent\npnpm exec tsx --expose-gc scripts/benchmarks/memory.bench.ts --workload=pi-session --count=10\n```\n\nJSON goes to stdout; a human-readable table and progress go to stderr.\n\n### Sample sizes\n\nPercentiles are nearest-rank: `sorted[ceil(p/100 · n) − 1]`. With too few samples the tail is meaningless — at `n = 30`, **p99 is literally the single slowest run** and p95 is the second slowest. Use enough iterations that the reported percentile is averaged over real tail samples, not one outlier:\n\n| Statistic | Minimum iterations |\n|---|--:|\n| p50 (median) | ~30 |\n| p95 | ~200 |\n| p99 | ~1,000 |\n\n`run-benchmarks.sh` uses `--iterations=2000` for cold start so p95/p99 are trustworthy. Memory per VM is a mean of per-VM step deltas with low variance, so `--count=20` (shell) / `--count=10` (agent) is sufficient.\n\n> The `pi-session` memory workload needs a working in-VM agent runtime (the Pi adapter process must launch inside the VM). On builds where the agent runtime is unavailable it will fail its process check rather than report a number.\n\n### Methodology\n\nEvery benchmark **creates the sidecar once up front** (`AgentOs.createSidecar()`) and leases all VMs from it. VMs are **incremental tenants of one shared sidecar process** — not one process each — so the figures measure the marginal cost of a VM, not a fresh process. (`AgentOs.create()` with no `sidecar` option already uses the shared `default`-pool sidecar, so this is the default everywhere, including RivetKit actors.)\n\nBefore any measured iteration, each benchmark does a **cold run** — a throwaway VM that is created, started, and (for cold start) snapshotted. This pays the one-time process spawn + bootstrap so the recorded numbers reflect the warm, steady-state incremental per-VM cost, never the first VM. The release sidecar is required: a debug build is several times slower and inflates the numbers.","src/content/docs/docs/benchmarks.mdx","8b389f84726bb5c2","docs/bindings",{"id":52,"data":54,"body":57,"filePath":58,"digest":59,"deferredRender":16},{"title":55,"description":56,"skill":16},"Bindings","Expose custom host functions to agents as CLI commands inside the VM.","Expose your host JavaScript functions (defined with Zod input schemas) to agents as auto-generated CLI commands installed at `/usr/local/bin/agentos-{name}` inside the VM, injected into the agent's [system prompt](/docs/system-prompt) and callable inside scripts for code-mode token savings.\n\n## Getting started\n\nDefine a bindings group with Zod input schemas and pass it to `agentOS()`.

Both work, but they have different tradeoffs.\n\n| | Bindings | MCP Servers |\n|---|---|---|\n| **How it works** | Call JavaScript functions on the host directly | Connect to a standard MCP server |\n| **Authentication** | None required. Direct binding to the agent's OS. | Requires custom auth configuration per server |\n| **Code mode** | Built-in. Bindings are exposed as CLI commands, so agents can call them inside scripts for up to 80% token reduction. | Requires extra work to make code mode work out of the box |\n| **Latency** | Near-zero. Bound directly to the host process. | Extra network hop to reach the MCP server |\n| **Setup** | Define bindings in your actor code with Zod schemas | Configure any standard MCP server |\n\nUse bindings when you want to expose your own JavaScript functions to agents. Use MCP servers when you want to connect to existing third-party services. See [Sessions](/docs/sessions#createsession-options) for MCP server configuration.\n\n## Security\n\nBinding calls from the agent securely invoke your `execute()` functions on the host. Your functions run with full access to the host environment, so you can call databases, APIs, and services directly without proxying credentials into the VM. The agent never sees the credentials, it only sees the binding's input/output contract.\n\nBindings run on the host with full access to the host environment, so do not expose bindings that could compromise the host without appropriate safeguards.","src/content/docs/docs/bindings.mdx","a88d54a3c6eadec8","docs/core",{"id":60,"data":62,"body":65,"filePath":66,"digest":67,"deferredRender":16},{"title":63,"description":64,"skill":16},"Core Package","Use @rivet-dev/agentos-core standalone for direct VM control without the Rivet Actor runtime.","## agentOS vs agentOS Core\n\nThe `agentOS()` actor (from `@rivet-dev/agentos`) wraps the core package and adds:\n\n| | Core (`@rivet-dev/agentos-core`) | Actor (`@rivet-dev/agentos`) |\n|-|---|---|\n| Persistence | In-memory by default (pluggable via [mounts](#mounts)) | Persistent filesystem and sessions |\n| Distributed state | Manage yourself | Built-in distributed statefulness |\n| Stateful VMs | Complex to run yourself | Built into Rivet |\n| Sleep/wake | Manual `dispose()` / `create()` | Automatic |\n| Events | Direct callbacks | Broadcasted to all connected clients |\n| Preview URLs | None | Built-in signed URL server |\n| Multiplayer | N/A | Multiple clients on same actor |\n| Orchestration | N/A | Workflows, queues, cron |\n| Agent-to-agent communication | Custom | Built into [Rivet Actors](/docs/agent-to-agent) |\n| Authentication | Set up yourself | [Documentation](/docs/authentication) |\n\nWe recommend using [Rivet Actors](https://rivet.dev/docs/actors) because they provide a portable way to run `agentOS()` on any infrastructure with built-in persistence, networking, and orchestration. Use the core package if you need the most bare-bones implementation possible.\n\n## Install\n\n```bash\nnpm install @rivet-dev/agentos-core\n```\n\n## Boot a VM\n\nCreate a VM and drive it directly — no actor runtime, no client/server split. `AgentOs.create()` boots the VM in-process and returns a handle you call directly:\n\n\u003CCodeSnippet file=\"examples/core/vm.ts\" region=\"boot\" title=\"vm.ts\" />\n\n## Sidecar process\n\nEvery VM runs inside a **shared sidecar process** rather than a process of its own. By default all VMs are tenants of a single, process-global sidecar (the `default` pool), so each additional VM only adds its marginal cost — a V8 isolate plus its kernel state — instead of a whole OS process. This is what keeps per-VM memory in the tens of MB and warm VM creation in the single-digit milliseconds (see [Benchmarks](/docs/benchmarks)).\n\nThis is automatic — `agentOS()` and `AgentOs.create()` use the shared default sidecar with no configuration, and the same applies to Rivet Actors (each actor's VM is a tenant of the shared process). Disposing a VM tears down only that VM; the shared sidecar process is reused across VMs and stays alive for the lifetime of the host process.\n\nFor advanced cases the core package exposes explicit sidecar handles so you can isolate a group of VMs in their own process:\n\n\u003CCodeSnippet file=\"examples/core/advanced.ts\" title=\"advanced.ts\" />\n\n## Filesystem\n\n\u003CCodeSnippet file=\"examples/core/vm.ts\" region=\"filesystem\" title=\"vm.ts\" />\n\n## Processes\n\nLong-running process output is delivered through the `onStdout`/`onStderr` callbacks you pass to `spawn`, and exit through `onProcessExit(pid, …)`:\n\n\u003CCodeSnippet file=\"examples/core/vm.ts\" region=\"processes\" title=\"vm.ts\" />\n\n## Agent sessions\n\n`createSession` resolves to a session record; all session operations take its `sessionId`. Session events and permission requests are delivered through per-session callbacks (`onSessionEvent` / `onPermissionRequest`):\n\n\u003CCodeSnippet file=\"examples/core/vm.ts\" region=\"sessions\" title=\"vm.ts\" />\n\nRegister `onSessionEvent` right after `createSession` so you do not miss the live stream — core session events are live-only and are not replayed.\n\n## Networking\n\n`fetch(port, request)` reaches a server running inside the VM:\n\n\u003CCodeSnippet file=\"examples/core/vm.ts\" region=\"networking\" title=\"vm.ts\" />\n\n## Cron jobs\n\nCron jobs run an `\"exec\"` command or a `\"session\"` prompt on a schedule. Fired jobs are surfaced through the `onCronEvent` callback:\n\n\u003CCodeSnippet file=\"examples/core/vm.ts\" region=\"cron\" title=\"vm.ts\" />\n\n## Mounts\n\nConfigure filesystem backends at boot time.\n\nNative mount plugins (host directories, S3, etc.) are passed via `plugin`, each\nidentified by an `id` and a `config` object.\n\n\u003CCodeSnippet file=\"examples/core/mounts.ts\" title=\"mounts.ts\" />\n\n## Configuration reference\n\nAll VM configuration is passed to `AgentOs.create()` as a single flat object. This is the consolidated config block to copy and adapt. The [`agentOS()` actor](/docs/quickstart) accepts the same options and layers persistence, sleep/wake, and preview URLs on top:\n\n\u003CCodeSnippet file=\"examples/core/config-reference.ts\" title=\"config-reference.ts\" />\n\nThe top-level fields are documented inline above. See [Mounts](#mounts) and [Software](/docs/software).\n\n### Session events\n\nWith the core package, session events and permission requests are observed per-session on the `AgentOs` instance. `onSessionEvent(sessionId, event)` fires once for every session event; `onPermissionRequest(sessionId, request)` fires when an agent requests permission. Both are live-only callbacks — register them right after `createSession`:\n\n\u003CCodeSnippet file=\"examples/core/hooks.ts\" title=\"hooks.ts\" />\n\n### Timeouts and sleep\n\nAction timeouts and automatic sleep/wake are features of the [`agentOS()` actor](/docs/quickstart), not the core package. A core VM stays alive until you call `dispose()`.

That changes the cost model for running coding-agent VMs from \"pay a provider per sandbox-second\" to \"pay for the compute you provision, then pack as much work onto it as it can hold.\" This page explains where the savings come from and how to reason about them honestly. It does not publish a single magic multiplier, because the real number depends on your workload, your hardware, and how you share VMs.\n\n\u003CNote>For measured latency (cold start, warm execution, and reuse fast paths), see [Benchmarks](/docs/benchmarks). This page is about cost structure, not raw performance.\u003C/Note>\n\n## Where the savings come from\n\nTwo structural differences drive the cost gap versus per-second sandbox providers:\n\n- **You run on your own hardware**: you choose the cloud, instance type, architecture, and region. A small commodity instance (for example an ARM VM from a budget host) costs a flat hourly or monthly rate that is typically far below what per-sandbox-second billing adds up to once you have steady agent traffic. You also avoid egress fees and vendor lock-in.\n- **You decide the isolation granularity**: sandbox providers bill a full container or microVM per execution, usually with a minimum memory reservation that you pay for even when your code uses a fraction of it. With agentOS you own the VM lifecycle: you can dedicate a VM per tenant or per task for maximum isolation, or amortize setup by reusing one VM across many runs.\n\n## The isolation model matters for cost\n\nEach `AgentOs.create()` boots a fully virtualized VM, and each `exec()` / `run()` inside it is a fresh guest process. That gives you a dial between isolation and density:\n\n- **One VM per task or tenant (strongest isolation)**: create a VM, run the work, and dispose it, or give each tenant its own VM. Each VM is its own crash and resource domain, with the highest per-VM overhead. Best when load is untrusted or bursty.\n- **A shared VM for trusted work**: reuse one VM across many runs to amortize the VM boot cost. Each `exec()` / `run()` still executes in a fresh guest process, so in-memory state does not leak between runs, but the VM and filesystem are shared. Good for trusted, sequential work.\n\nThe denser you can safely pack agent work onto an instance, the lower your effective cost per execution. See [Resource Limits](/docs/resource-limits) for the per-VM caps that govern how densely you can pack, and [Processes & Shell](/docs/processes) for how guest processes run inside a VM.\n\n## How to estimate your own cost\n\nBecause agentOS runs on hardware you provision, the honest way to compare is to plug in your own numbers:\n\n1. **Pick your hardware and its rate**: take the hourly or monthly price of the instance you would run on, and divide down to a per-second instance cost.\n2. **Estimate how many concurrent VMs fit**: measure per-VM memory overhead on your target hardware under your isolation strategy, then divide your usable RAM by that figure. Leave headroom (the measurement and any orchestration layer will not bin-pack perfectly).\n3. **Divide instance cost by concurrent VMs**: that gives a cost-per-VM-second you can compare against a provider's per-sandbox-second rate.\n\n\u003CTip>Measure on the hardware and isolation strategy you will actually deploy. Per-VM overhead depends on whether you create a fresh VM per task or reuse one across runs, and on the work the agent does, so a number measured on one machine will not transfer cleanly to another.\u003C/Tip>\n\n## Comparing against sandbox providers\n\nWhen you do compare against a per-second sandbox provider, hold the methodology honest:\n\n- **Sandbox cost** is the provider's minimum allocatable memory times their per-GiB-second rate (plus any egress and platform fees). The minimum reservation is the floor you pay even for tiny workloads.\n- **agentOS cost** is your instance cost per second divided by the number of VMs you can keep live on it, with realistic headroom for bin-packing inefficiency.\n\nThe advantage is largest for **many small, short executions**, where a per-sandbox minimum reservation dominates and your own hardware lets you pack densely. It narrows for **heavyweight, long-lived workloads** (for example dev servers that need hundreds of megabytes regardless), where the win shifts from density to hardware choice: you still avoid per-second metering, egress fees, and lock-in, but the raw memory-density advantage is smaller.\n\n| Workload | Primary cost advantage |\n| --- | --- |\n| Many small, short executions | Density: pack many VMs per instance, no per-sandbox minimum |\n| Heavyweight, long-lived workloads | Hardware choice, flat instance pricing, no egress or lock-in |\n| High concurrency | Reuse a VM across runs to amortize VM boot cost |\n\n\u003CWarning>Be careful generalizing cost ratios from a single benchmark. Provider pricing, instance pricing, and exchange rates change over time, and per-VM overhead varies by workload and isolation strategy. Re-measure on your own hardware before quoting a number.\u003C/Warning>\n\nWhen you do need a full Linux sandbox for heavier agent workloads, see [agentOS vs Sandbox](/docs/versus-sandbox) for how the two models combine.","src/content/docs/docs/cost-evaluation.mdx","d061affd8af70768","docs/crash-course",{"id":84,"data":86,"body":89,"filePath":90,"digest":91,"deferredRender":16},{"title":87,"description":88,"skill":16},"Crash Course","Run coding agents inside isolated VMs with full filesystem, process, and network control.","\u003CNote>\nagentOS is in preview and the API is subject to change.

Capture it with `onAgentStderr` on the VM:\n\n\u003CCodeSnippet file=\"examples/debugging/agent-logs.ts\" />\n\nIt's a VM-level option covering every session's agent process; if omitted, chunks are written to the host `process.stderr` by default. See [Sessions → Agent logs](/docs/sessions#agent-logs).\n\n## Agent crashes (`onAgentExit`)\n\nIf the agent process exits without `closeSession()`, the runtime logs the exit, **auto-restarts the agent** (bounded to 3 restarts per session, re-attaching the same session id when the agent supports native resume), and fires `onAgentExit` with the outcome:\n\n```ts\nconst agentOs = await AgentOs.create({\n software: [pi],\n onAgentExit(event) {\n // event: { sessionId, agentType, processId, pid, exitCode,\n // restart: \"restarted\" | \"unsupported\" | \"failed\" | \"exhausted\",\n // restartCount, maxRestarts }\n console.warn(`agent exited (code ${event.exitCode}), restart=${event.restart}`);\n },\n});\n```\n\nOnly `restart === \"restarted\"` leaves the session usable; every other outcome means the session was evicted. The crash *reason* is on the agent's stderr (above); the exit event tells you it died and whether it recovered. See [Sessions → Agent crashes and auto-restart](/docs/sessions#agent-crashes-and-auto-restart).\n\n## Runtime logs (sidecar)\n\nThe agentOS sidecar emits structured **logfmt** logs for request handling, networking, and lifecycle.

Default `info`. |\n| `RUST_LOG_FORMAT` | `logfmt` (default) or `text` |\n| `AGENTOS_LOG_FILE` | append logs to this file instead of stderr (never stdout, which carries the wire protocol) |\n| `AGENTOS_MAX_SESSIONS_PER_CONNECTION` | maximum open wire sessions on one sidecar connection; defaults to `1024`.

Every guest VM executes its JavaScript inside this runtime, fully sandboxed from the host.\n\n## JavaScript Acceleration\n\n- **JavaScript is unusually slow as WebAssembly**: unlike most software, JavaScript pays a heavy penalty when compiled to WebAssembly, because so much engineering has gone into JIT-compiling JavaScript directly in V8.\n- **Native V8, full JIT**: agentOS therefore runs guest JavaScript on the native V8 engine with its full JIT compiler, not through a WASM translation layer. We call this **JavaScript Acceleration**.\n- **Native-speed execution**: guest JavaScript runs at native speed while staying inside the isolation boundary, with normal Node.js semantics.\n\n## Comparison to Node.js efficiency\n\n- **Isolate model, not processes**: agentOS runs each agent inside a V8 isolate rather than spawning a full Node.js process per agent.\n- **Low memory overhead**: an isolate carries far less per-agent memory overhead than a full Node.js process, so many agents fit in the footprint that a process-per-agent model would spend on a handful.\n- **Benchmarks**: see the Secure Exec [benchmarks](https://secureexec.dev/docs/benchmarks) for cold start, warm execution, and reuse measurements.\n\n## Node.js compatibility\n\nGuest code runs as Node.js (reporting `process.version` as `v22.0.0`), but it never touches the host runtime. Every `node:` builtin resolves to a kernel-backed bridge or an in-isolate polyfill, never the real host module. For the full builtin matrix (`fs`, `net`, `http`, `crypto`, undici-backed `fetch`, and more), see the Secure Exec [Node.js Compatibility](https://secureexec.dev/docs/nodejs-compatibility) reference.\n\n### npm packages\n\nBy default the VM has no npm packages installed. Mount a host `node_modules` directory to give guest code access to real packages: the `nodeModulesMount` helper projects it read-only at `/root/node_modules`, and the in-kernel resolver walks it exactly like Node.js does, with no bundling or patching.\n\n\u003CCodeSnippet file=\"examples/js-runtime/node-modules-mount.ts\" />\n\nResolution matches naive Node.js over the mounted tree: the ancestor `node_modules` walk, `package.json` `exports`/`imports` and conditions, and `realpath`/symlink following (so pnpm and yarn layouts resolve too).

In agentOS, JavaScript runs inside a native V8 isolate (powered by [Secure Exec](https://secureexec.dev)) for native runtime speeds:\n\n- **Native V8 speed, no overhead** — guest JS runs on V8's full JIT, not a WASM translation layer.\n- **Lower memory than a Node.js process** — each agent is a V8 isolate, not a full process, so many fit where process-per-agent fits a handful. See [benchmarks](https://secureexec.dev/docs/benchmarks).\n\n## Running Node\n\n```ts\nawait agent.exec('node -e \"console.log(1 + 1)\"'); // inline\nawait agent.exec(\"node /workspace/main.js a b\"); // script + argv\nawait agent.exec(\"npx tsx script.ts\"); // npx\nawait agent.exec('echo \"console.log(42)\" | node'); // stdin\n```\n\n`node` works directly (`exec` / `execArgv` / `spawn`), through the guest shell (`sh -c`, pipes), and as a REPL.\n\n## Installing packages\n\n### Ahead of time\n\nMount a host `node_modules` tree — projected read-only at `/root/node_modules` and resolved exactly like Node.js (ancestor walk, `package.json` `exports`/`imports`, symlinks — so pnpm/yarn layouts work), for both `import` and `require`:\n\n```ts\nimport { agentOS, setup, nodeModulesMount } from \"@rivet-dev/agentos\";\n\nconst vm = agentOS({\n mounts: [nodeModulesMount(\"/absolute/path/to/node_modules\")],\n});\n```\n\n### At runtime\n\nOr install in the VM mid-task:\n\n```ts\nawait agent.exec(\"npm install chalk\");\nawait agent.exec(\"node /workspace/app.js\"); // app.js: require(\"chalk\")\n```\n\n## Node.js compatibility\n\nGuest code runs as Node.js v22, isolated from the host. `node:` builtins — `fs`, `net`, `http`, `crypto`, undici-backed `fetch`, and more — are provided by the runtime, never the host's.

Every guest syscall the agent's sandboxed code makes is checked against a per-scope policy before any host resource is touched.\n\n- **Six scopes**, configured independently: `fs`, `network`, `childProcess`, `process`, `env`, `binding`.\n- **Each scope** is a mode (`\"allow\"` or `\"deny\"`), or a rule set.\n- **A denied operation** is rejected with `EACCES` before any host resource is touched.\n- **Omitted top-level scopes inherit the sidecar allow-all default**, so partial policies remain explicit overrides.\n\nFor the higher-level agent tool-approval layer (human-in-the-loop, auto-approve), see [Approvals](/docs/approvals).\n\n## Defaults and merge semantics\n\nOmitting `permissions` selects the sidecar-owned allow-all product default. All six scopes—`fs`, `network`, `childProcess`, `process`, `env`, and `binding`—are `allow`.\n\nAn explicit partial top-level policy changes only the scopes it names. Omitted top-level scopes inherit `allow`. Inside an explicit rule-set scope, an omitted `default` means `deny`; set `default: \"allow\"` for a deny-list or `default: \"deny\"` for an allow-list.\n\nAllow-all authorizes only capabilities present inside or explicitly configured for the VM. It does not expose the host filesystem, host process table, or unrestricted host sockets.\n\n## Permission scopes\n\n| Scope | Controls | Default |\n|---|---|---|\n| `fs` | Filesystem reads, writes, and metadata operations | `allow` |\n| `network` | Outbound connections: `fetch`, HTTP, DNS, and inbound `listen` | `allow` |\n| `childProcess` | Spawning child processes | `allow` |\n| `process` | Process-control operations | `allow` |\n| `env` | Environment variable access | `allow` |\n| `binding` | Invoking bindings registered with the runtime | `allow` |\n\n## Bind a policy to the VM\n\nA policy is a plain object keyed by scope. Pass it as `permissions` to `agentOS(...)` and it gates every guest syscall on that VM.\n\n\u003CCodeSnippet file=\"examples/permissions/bind-policy.ts\" />\n\n## Grant or deny a whole scope\n\nThe simplest value for a scope is a single mode string. `\"allow\"` permits every operation in the scope; `\"deny\"` rejects every one with `EACCES`. Omitted top-level scopes inherit `allow`, so list every scope that must be restricted.\n\n```ts\nconst permissions = {\n\tnetwork: \"deny\", // turn off network egress\n\tfs: \"deny\", // turn off all filesystem access\n};\n```\n\nThere is no typed `\"ask\"` mode. Interactive, human-in-the-loop approval lives in the higher-level [Approvals](/docs/approvals) layer, not the kernel policy. To block at the kernel level, use `\"deny\"`.\n\n## Allow only specific filesystem paths\n\nFor finer control, a scope can be a rule set instead of a bare mode: a `default` mode plus an ordered list of `rules`. The `fs` scope matches by `paths` (filesystem globs). Each rule names its `operations` (`read`, `write`, `stat`, `readdir`, `create_dir`, `rm`, `rename`, `symlink`, `readlink`, `chmod`, `truncate`, `mount_sensitive`, or `[\"*\"]` for all). Last matching rule wins; if no rule matches, `default` applies.\n\n\u003CCodeSnippet file=\"examples/permissions/fs-rules.ts\" region=\"deny-vault\" />\n\nTo invert it, flip `default` to `\"deny\"` and allow just one subtree:\n\n\u003CCodeSnippet file=\"examples/permissions/fs-rules.ts\" region=\"allow-only-data\" />\n\n## Allow only specific network hosts\n\nEvery non-`fs` scope matches by `patterns` instead of `paths`. For `network`, a pattern is a host (or `host:port`), and the operations are `fetch`, `http`, `dns`, and `listen`.\n\n\u003CCodeSnippet file=\"examples/permissions/server.ts\" region=\"allow-one-host\" />\n\n## Allow only specific bindings\n\nBindings registered with the runtime are gated by the `binding` scope, matched by name via `patterns`. Bindings have no sub-operations, so pass `[\"*\"]` for `operations`.\n\n\u003CCodeSnippet file=\"examples/permissions/server.ts\" region=\"allow-one-binding\" />\n\nThe `childProcess`, `process`, and `env` scopes work the same way: `childProcess` patterns match the command (`operations: [\"spawn\"]`), `env` patterns match the variable name (`operations: [\"read\", \"write\"]`), and `process` is matched by pattern with `operations: [\"*\"]`.\n\n## Combine policies and see denials\n\nEach policy above sets one scope, so you can spread several into one `permissions` object and bind them together.\n\n\u003CCodeSnippet file=\"examples/permissions/combine.ts\" />\n\nWhen a scope or matching rule denies an operation, the kernel rejects it with `EACCES` before any host resource is touched.

public frontend or another backend. The same `vm` actor is reachable from a plain Node script, a browser/React app, or a separate server.\n\n \u003CCodeGroup>\n \u003CCodeSnippet file=\"examples/quickstart-app/client.ts\" />\n\n \u003CCodeSnippet file=\"examples/quickstart-app/Agent.tsx\" />\n \u003C/CodeGroup>\n\n4. **Run it**\n\n Start the server, then run the client in a second terminal:\n\n ```bash\n # Terminal 1: start the server\n npx tsx server.ts\n\n # Terminal 2: run the client\n npx tsx client.ts\n ```\n\n5. **Customize**\n\n Now that you have a working agent, customize it to fit your needs:\n\n - **[Software](/docs/software)** — Install software packages inside the VM\n - **[Filesystem](/docs/filesystem)** — Read, write, and manage files inside the VM\n - **[Permissions & Resource Limits](/docs/permissions)** — Gate what the agent can do and cap its resource usage\n - **[Bindings](/docs/bindings)** — Expose your JavaScript functions to agents as CLI commands\n\n5. **Deploy**\n\n By default, agentOS runs locally with `npx rivetkit dev` — no infrastructure needed. To run in production, deploy to any of these targets:\n\n \u003CDeployTargets />\n\n See [Deployment](/docs/deployment) for managed, self-hosted, and agentOS Core options.\n\n\u003C/Steps>\n\n\u003CNote>\nagentOS is in preview and the API is subject to change.

Runaway or malicious guest code can exhaust its own VM, but it can never starve the host or any sibling VM.\n\n- **Bounded by default**: each VM ships with conservative caps. Unset fields fall back to built-in defaults that match the runtime's historical constants.\n- **Per-VM**: every VM gets its own budget. Limits are not shared across VMs.\n- **Enforced by the sidecar/runtime**: a guest that exceeds a cap fails inside the VM (out-of-memory, `EMFILE`, `EAGAIN`, runtime timeout, etc.). The host is never affected.\n- **Operator-raisable**: the operator (the trusted process that creates the VM) may raise any cap for trusted workloads. Guest code can never raise its own caps.\n\n## Setting limits\n\nSet caps on the `limits` object in the `agentOS` config. Limits are grouped by subsystem (`resources`, `jsRuntime`, `python`, `wasm`, and more). Omitted limits keep their secure default.\n\n\u003CCodeSnippet file=\"examples/resource-limits/server.ts\" />\n\n## Available caps\n\n| Limit | Controls | Notes |\n|---|---|---|\n| `resources.maxProcesses` | Concurrent processes in the VM process table | Caps fork bombs and runaway spawning. New spawns fail with `EAGAIN`. |\n| `resources.maxCapturedOutputBytes` | Aggregate bytes retained by all active captured processes | Default is `32 MiB`; concurrent `exec` captures share this sidecar-owned VM budget. |\n| `resources.maxOpenFds` | Open file descriptors | Exhausting the table fails with `EMFILE` / `ENFILE`. |\n| `resources.maxSockets` | Open sockets in the socket table | Bounds concurrent connections; excess `connect`/`accept` fail. |\n| `resources.maxFilesystemBytes` | Total bytes stored in the virtual filesystem | Bounds VFS storage; writes past the budget fail with a no-space error. |\n| `resources.maxWasmFuel` | WASM execution budget | Bounds WASM execution work; unset means no explicit fuel budget. |\n| `resources.maxWasmMemoryBytes` | WASM linear memory, in bytes | Default is `128 MiB`. |\n| `resources.maxWasmStackBytes` | Maximum WASM call-stack size, in bytes | Deep recursion fails with a stack overflow instead of crashing the VM. |\n| `jsRuntime.v8HeapLimitMb` | Guest JavaScript V8 heap, in MiB | Default is `128`. |\n| `jsRuntime.cpuTimeLimitMs` | Active JavaScript CPU time | Default is `30000`; `0` disables the CPU watchdog. |\n| `jsRuntime.wallClockLimitMs` | JavaScript elapsed wall-clock backstop | Default is `0`, disabled. Use this for finite commands, not long-lived adapters. |\n| `jsRuntime.importCacheMaterializeTimeoutMs` | Node import-cache materialization timeout | Default is `30000`. |\n| `jsRuntime.syncRpcWaitTimeoutMs` | JavaScript sync host-RPC wait | Unset keeps the engine default, currently `30000`. |\n| `jsRuntime.capturedOutputLimitBytes` | Captured JavaScript stdout or stderr bytes per stream | Default is `16 MiB`; enforced by the sidecar when a host `exec` call requests a buffered result. |\n| `python.executionTimeoutMs` | Python execution wall-clock timeout | Default is `300000`. |\n| `python.maxOldSpaceMb` | Pyodide runner V8 old-space heap, in MiB | Default is `0`, which keeps the engine default. |\n| `python.outputBufferMaxBytes` | Captured Python stdout or stderr bytes per stream | Default is `1 MiB`; enforced by the sidecar when a host `exec` call requests a buffered result. |\n| `wasm.prewarmTimeoutMs` | WASM compile-cache warmup timeout | Default is `30000`. |\n| `wasm.runnerHeapLimitMb` | Trusted WASI/WASM runner V8 heap, in MiB | Default is `2048`; this is not guest linear memory. |\n| `wasm.capturedOutputLimitBytes` | Captured WASM stdout or stderr bytes per stream | Default is `16 MiB`; enforced by the sidecar when a host `exec` call requests a buffered result. |\n\n## Behavior at the limit\n\n- **WASM stack**: deep recursion throws a stack-overflow error in the guest, never a host crash.\n- **JavaScript CPU time**: CPU-bound loops terminate with a CPU-budget error once active JS CPU exceeds `jsRuntime.cpuTimeLimitMs`.\n- **JavaScript wall time**: awaiting or blocked JS terminates only when you set `jsRuntime.wallClockLimitMs`; the default is disabled for long-lived adapters.\n- **Filesystem bytes**: writing past the VFS budget fails with a no-space error to the guest.\n- **Counts (fds / processes / sockets)**: hitting a table cap returns the standard POSIX errno (`EMFILE`, `EAGAIN`, etc.), exactly as a real Linux kernel would under `ulimit`.\n- **Captured process output**: `exec` asks the sidecar to bound the buffered\n result and return it on the terminal protocol event. If either stdout or\n stderr crosses its runtime-specific capture limit, the process is killed and the call fails with\n `ERR_CAPTURED_OUTPUT_LIMIT_EXCEEDED`, naming the configured limit to raise.\n Concurrent captures also share `resources.maxCapturedOutputBytes`; the\n process whose next chunk would cross that VM-wide budget fails with the same\n typed error naming the aggregate limit. Completed terminal frames are\n backpressured like a pipe instead of accumulating in a large sidecar queue.\n Raw `spawn` output and `captureStdio: false` remain streaming interfaces and\n do not accumulate a sidecar result buffer; stream callbacks still receive the bytes.\n The default negotiated wire-frame cap is `64 MiB`, which fits both default\n JavaScript/WASM `16 MiB` capture streams (or both Python `1 MiB` streams) plus\n terminal-event overhead. Explicit capture limits that cannot both fit the\n configured frame cap are rejected when the VM is created.\n\n## Sidecar liveness\n\nSeparate from the guest caps above, the host detects a dead or wedged sidecar\nprocess by silence, not by per-request deadlines. The sidecar emits a liveness\nheartbeat every 10 seconds from a dedicated thread — so it keeps beating even\nmid-way through a long turn — and the host treats 30 seconds with no inbound\nframes at all as a dead sidecar: it kills the process and fails in-flight\nrequests with a typed `SidecarSilenceTimeout` error.\n\nBecause liveness is silence-based, individual requests have no time limit of\ntheir own: an agent turn may legitimately run for many minutes without being\ntorn down. Neither the heartbeat cadence nor the silence window is\nconfigurable — they are fixed protocol constants.\n\n## Warnings & observability\n\nLimits are observable, not just enforced. Every bound — resource caps and the\ninternal bounded queues alike — is tracked in a central limit registry that:\n\n- **Warns before the limit is hit.** As usage crosses ~80% of a cap, the runtime\n emits a structured warning (once per crossing, re-armed only after it recovers),\n so a slow consumer or a runaway guest is visible *before* it fails.\n- **Applies backpressure instead of failing catastrophically.** The internal\n queues between the guest, the runtime, and the host block their producer when\n full rather than dropping data or tearing down the session — so a transient\n burst degrades to \"slower\", not \"broken\".\n- **Surfaces through logs.** secure-exec logs to stderr (stdout is the wire\n protocol); set `AGENTOS_LOG=warn` (the default) to see near-limit warnings\n or `AGENTOS_LOG=debug` for live per-limit usage snapshots.\n\nSee [Limits & Observability](/docs/architecture/limits-and-observability) for the\nfull architecture.","src/content/docs/docs/resource-limits.mdx","564e0f46af35df1a","docs/sandbox",{"id":234,"data":236,"body":239,"filePath":240,"digest":241,"deferredRender":16},{"title":237,"description":238,"skill":16},"Sandbox Mounting","Extend agentOS with full sandboxes for heavy workloads like browsers, desktop automation, and compilation.","For heavy workloads like browsers, desktop automation, and compilation, pair agentOS with a full sandbox on demand. Its filesystem mounts into the VM as a native directory, and its process management is exposed as [bindings](/docs/bindings), all provider-agnostic through [Sandbox Agent](https://sandboxagent.dev).\n\n## Why use agentOS with a sandbox?\n\nagentOS is an alternative to sandboxes that covers most use cases, but some workloads need a full sandbox for special kinds of software (browsers, desktop automation, heavy compilation). Sandbox mounting lets you lazily start a sandbox on demand, only when it is needed, and project it into the VM. The hybrid model means one agent session can handle both lightweight coding tasks and heavy system operations, using the right tool for each.\n\nSee [agentOS vs Sandbox](/docs/versus-sandbox) for a detailed comparison.\n\n## When to use a sandbox\n\n- **Native binaries** not yet supported in the agentOS runtime.\n- **Browsers and desktop automation**: Playwright, Puppeteer, Selenium, or anything that needs a display server.\n- **Heavy compilation**: Large builds or native toolchains that require a full Linux environment.\n- **GUI applications**: Desktop apps, VNC sessions, or any workload that needs a graphical environment.\n- **Node.js packages with native extensions** (e.g. `sharp`, `bcrypt`, `better-sqlite3`) that require a full build toolchain.\n\nStart with the default agentOS VM for all workloads, and only spin up a sandbox when a task genuinely requires one. Sandboxes are billed per second of uptime, so start them on demand and tear them down when the task is done.\n\n## Getting started\n\nThe sandbox integration ships as the `@rivet-dev/agentos-sandbox` package. It works through two mechanisms:\n\n- **Filesystem mount**: Projects the sandbox into the VM as a native directory, like mounting a hard drive on your own machine. Read and write files through the mount directly.\n- **Bindings**: Exposes sandbox process management as [bindings](/docs/bindings). Execute commands on the sandbox from within the VM.\n\nBoth are powered by [Sandbox Agent](https://sandboxagent.dev), and you can swap providers without changing agent code. Install both packages:\n\n```bash\nnpm install @rivet-dev/agentos-sandbox sandbox-agent\n```\n\n`createSandboxFs` and `createSandboxBindings` come from `@rivet-dev/agentos-sandbox`. `SandboxAgent` and the provider helpers (such as `docker`) come from the `sandbox-agent` package.\n\nPass a provider as `sandbox: { provider: docker() }`. Agent OS starts a Sandbox Agent client, mounts it at `/mnt/sandbox`, registers the process bindings, and disposes the sandbox client when the VM is disposed. In RivetKit actors, pass the provider directly to `agentOS(...)`; the provider starts a fresh client for each actor VM.\n\n\u003CCodeGroup>\n\u003CCodeSnippet file=\"examples/sandbox/server.ts\" />\n\u003C/CodeGroup>\n\n## Calling the mounted bindings\n\nOnce the sandbox is mounted, write code through the filesystem and run it inside the sandbox. The sandbox bindings are exposed inside the VM as a CLI command, so you call it through the same `exec`/`spawn` surface as any other command.\n\n\u003CCodeSnippet file=\"examples/sandbox/client.ts\" />\n\n## Bindings reference\n\nThe bindings expose these commands inside the VM:\n\n```bash\n# Run a command synchronously\nagentos-sandbox run-command --command \"npm install\" --cwd \"/app\"\n\n# Start a background process\nagentos-sandbox create-process --command \"npm\" --args \"run\" --args \"dev\"\n\n# List running processes\nagentos-sandbox list-processes\n\n# Get process output\nagentos-sandbox get-process-logs --id \"proc_abc123\"\n\n# Stop or kill a process\nagentos-sandbox stop-process --id \"proc_abc123\"\nagentos-sandbox kill-process --id \"proc_abc123\"\n\n# Send input to an interactive process\nagentos-sandbox send-input --id \"proc_abc123\" --data \"yes\"\n```\n\n## Sandbox providers\n\nThe extension works with any [Sandbox Agent](https://sandboxagent.dev) provider. See the [Sandbox Agent documentation](https://sandboxagent.dev) for available providers and setup instructions.","src/content/docs/docs/sandbox.mdx","86ef3008884681d2","docs/security-model",{"id":242,"data":244,"body":247,"filePath":248,"digest":249,"deferredRender":16},{"title":245,"description":246,"skill":16},"Security Model","Trust boundaries, isolation guarantees, and the agentOS threat model.","\u003CWarning>\nagentOS is in beta and still undergoing security review. The security model described here is subject to change.\n\u003C/Warning>\n\nagentOS is a sandbox: it runs **untrusted code safely on behalf of a trusted caller**. Every actor boots its own fully virtualized VM with a virtual filesystem, process table, socket table, pipes, PTYs, a permission policy, and managed language runtimes. Guest JavaScript executes in a V8 isolate, and every guest syscall is serviced by the kernel rather than the host. There are no host escapes: guest code cannot spawn a real host process, touch the real host filesystem, or open a real host network socket.\n\n## Sidecar-enforced permissions\n\nThe sidecar resolves omitted permissions to allow-all inside the VM. Callers running untrusted workloads should pass explicit denies or allowlists.\n\n- **Network operations** are allowed when the scope is omitted, but remain confined to the VM network and its configured egress controls.\n- **Filesystem mounts** expose nothing of the host until you configure them.\n- **Process spawning** runs only kernel-managed guest processes, never host processes.\n- **All other host capabilities** must be configured by the host before the VM can use them.\n\nOther in-VM scopes (the virtual filesystem, child processes, process info, env) are enabled so that normal programs run, but they are mediated entirely by the kernel and never touch the host.\n\n## Trust model: three components\n\nBefore judging whether something is a security bug, decide which side of the boundary it is on. agentOS has three components with very different trust levels.\n\n\u003Csvg width=\"700\" height=\"270\" viewBox=\"0 0 700 270\" xmlns=\"http://www.w3.org/2000/svg\" role=\"img\"

it sends** are trusted: VM config, mount descriptors and their plugin configs (host directory paths, S3 endpoints and credentials, etc.), the permission policy, network allowlist, resource limits, env, and DNS overrides.\n- **Configuration is not an attack surface.** A defect that requires the client to supply a malicious config, endpoint, credential, or policy is not a sandbox vulnerability: the client is configuring its own VM and already controls the host.\n- The **one** thing from the client that is *not* trusted is the **code/payload** it asks to run, because that runs in the executor. How code reached the executor never makes it trusted.\n\nYou are responsible for hardening this side. See [What you are responsible for](#what-you-are-responsible-for).\n\n### Sidecar / kernel (trusted, the enforcement point)\n\nThe trusted computing base. It brokers client requests and owns the kernel, VFS, mount/plugin registry, socket table, and permission policy. It is responsible for enforcing the boundary against the executor.\n\n### Executor (untrusted, the adversary)\n\nV8 isolates or WASM running guest JS/Python/WASM plus any third-party, npm, or agent-generated code.\n\n- Assume everything here is **actively hostile**.\n- The executor reaches the outside world only through kernel-owned VFS, process, socket, pipe, PTY, permission, and DNS paths.\n\n## The security boundary\n\n**The security boundary is sidecar ↔ executor.** The runtime must stop guest code in the executor from:\n\n- Escaping the kernel boundary (the real host filesystem, network, process table, or memory).\n- Bypassing the **applied** permission policy, allowlist, or limits.\n- Exhausting host resources beyond configured bounds.\n- Reading another VM's state.\n\nTwo corollaries that are easy to get wrong:\n\n- **Trusted policy, untrusted subject.** The permission policy and limits are trusted input, but the guest executor is the subject they bind. \"Guest bypasses an applied permission, egress rule, or resource cap\" is in-scope and serious. Trusted = who sets the rule; untrusted = who is bound by it.\n- **Trusted mount, untrusted traffic.** A host-backed mount (host directory, S3, etc.) comes from trusted config, so its existence, target, and credentials are not attack surface. But the guest drives I/O through it, so confining those guest operations to the mount root (symlink, `..`, TOCTOU, and path-aliasing escapes) is in-scope.\n\n### In scope vs out of scope\n\n| In scope (sandbox escape) | Out of scope (not a sandbox bug) |\n| --- | --- |\n| Guest reaches the real host fs / net / process / memory | Client supplies a malicious config / endpoint / credential / policy |\n| Guest bypasses an applied permission, egress rule, or limit | Hardening that only guards trusted client-provided configuration |\n| Guest exhausts host resources past configured bounds | Wire-level authn/authz between mutually distrusting clients |\n| Guest reads another VM's state | VM-to-VM access via forged connection IDs (single-client transport) |\n| Guest escapes a host-backed mount root (symlink / `..` / TOCTOU) | The existence or target of a configured mount |\n\n**Transport scope.** The wire protocol is same-version lockstep and single-client over stdio (one trusted client per sidecar process). There is no second, mutually-distrusting client, so wire-level authn/authz between clients and VM-to-VM access via forged connection IDs are out of scope until a multi-client transport exists.\n\n## VM isolation\n\nEach agentOS actor runs in its own isolated VM.\n\n- **Sandboxed execution.** All agent code runs inside a V8 isolate with WebAssembly. No code escapes the isolate boundary.\n- **Virtual filesystem.** The VM has its own in-memory filesystem. Guest reads and writes never reach the real host filesystem. Agents cannot access host files unless explicitly mounted.\n- **Virtual network.** The VM has no direct access to the host network. Outbound requests are proxied through the host with configurable controls.\n- **Process isolation.** No host process is visible or accessible from inside the VM.\n- **Per-actor containment.** Each actor is its own VM. Two actors share no filesystem, globals, module state, memory, or crash fate. The sidecar process that hosts those VMs may be shared by default as a performance optimization, but isolation is enforced at the VM level, not the host-process level.\n\n### Kernel-owned syscall paths\n\nEvery guest syscall is mediated by the kernel and checked against the runtime's permission policy. Concretely, the kernel mediates:\n\n- **Filesystem.** A virtual, in-memory filesystem. Guest reads and writes never reach the real host filesystem. Host data enters the VM only through the `files`, `mounts`, or `nodeModules` you configure explicitly. See [Filesystem](/docs/filesystem).\n- **Processes.** `node:child_process` spawns kernel-managed guest processes, never real host processes. Children can only run the commands the VM mounts (WASM-backed `sh` and coreutils, V8-backed `node`). See [Processes](/docs/processes).\n- **Network.** Guest `fetch()`, `node:http`, and raw sockets all flow through the kernel socket table. Guest `fetch()` runs through undici inside the isolate and then through the kernel socket table; it never opens a real host socket. See [Networking](/docs/networking).\n- **DNS, pipes, and PTYs** are likewise kernel-owned: no guest path reaches the host directly.\n- **Bindings.** Registered [bindings](/docs/bindings) are the only sanctioned way to hand the guest a named host capability. The guest invokes a binding by name with JSON input, the call round-trips to the host handler, and only the handler's return value comes back. The guest never receives the underlying host access.\n\n## What enters the VM\n\nThe host filesystem is never exposed to the guest by default. Host data crosses the boundary only through options you configure:\n\n- **`files`** seed bytes into the virtual filesystem. The bytes are copied in; the host path is never exposed.\n- **`mounts`** project a host directory at a guest path, Docker-style. The guest sees only the mounted subtree, read through the VFS lazily, never the wider host filesystem. Mounts are read-only unless you opt out.\n- **`nodeModules`** project a host `node_modules` directory (read-only, lazily) at a guest path so guest `import`/`require` resolves real installed packages.\n\nIn every case the guest sees only the subtree you mount, and writes to read-only mounts are rejected.\n\n## Permissions\n\nPermissions are the capability gate at the boundary. The sidecar resolves omitted permissions to allow-all before installing the policy in the kernel; a partial policy leaves omitted top-level scopes allowed. Permission does not create a host capability: filesystem and process access still address VM-owned resources unless the trusted host explicitly configures more.\n\n```ts\n// Restrict the allow-all omission default.\npermissions: { network: \"deny\" }\n```\n\nA scope can be `\"allow\"`, `\"deny\"`, or a `{ default, rules }` policy that matches request patterns. Guest servers are reachable only over loopback inside the VM unless you exempt a port explicitly. See [Permissions](/docs/permissions) and [Networking](/docs/networking) for the full policy shape.\n\n## Resource and timing limits\n\nThe VM bounds guest execution so runaway or hostile code cannot hang or exhaust the host:\n\n- **Timeouts and cancellation** kill or cancel a run from the outside.\n- **Memory, CPU-time, and payload limits** are enforced by the VM.\n- **Timing-side-channel mitigation.** In the default mode, high-resolution clocks (`Date.now()`, `performance.now()`, `process.hrtime()`) are frozen within a run and `SharedArrayBuffer` is removed, to blunt timing side channels of the kind used in Spectre-style attacks.\n\nSee [Security & Auth](/docs/security-model) for resource limits, network control, and authentication setup.\n\n## What agentOS guarantees\n\n- Agent code cannot read or write host files outside configured mounts.\n- Agent code cannot make network requests except through the host proxy.\n- Agent code cannot access host environment variables or secrets.\n- Each actor's filesystem, sessions, and state are isolated from other actors.\n- Resource limits (CPU, memory) are enforced at the VM level.\n- A crash, resource exhaustion, or escape attempt is contained to a single VM; other VMs keep running, even when they share a sidecar process.\n\n## What you are responsible for\n\nThe boundary protects the host from the guest. It does **not** harden your host process against everything else. The VM alone is not enough without a hardened host, and a hardened host alone does not protect against code that runs with full host access inside your own process.\n\n- Hardening the host process and deployment environment. For internet-facing workloads that take untrusted input, run your host inside an already-hardened environment (for example AWS Lambda, Google Cloud Run, or a similar sandboxed platform).\n- Validating authentication tokens in `onBeforeConnect`.\n- Scoping [permissions](/docs/permissions) appropriately for your use case.\n- Managing API keys and secrets on the host side (use the [LLM gateway](/docs/llm-gateway) to avoid passing keys into the VM).\n- Configuring [resource limits and network controls](/docs/security-model) to match your threat model.\n- Choosing your blast radius: prefer a fresh VM per untrusted or high-risk task so an escape attempt cannot outlive a single VM.\n\n\u003CWarning>The boundary contains guest code, but you still own the host.

Sessions are ephemeral, so keep their lifetime scoped to one unit of work.\n- Pass data between steps via the filesystem or step return values, not session state.\n- Keep `state` changes and other actor-local side effects inside `ctx.step()` callbacks; use non-step workflow code (queue waits, loops, sleeps) only for orchestration.\n- Reach the agentOS VM, a separate actor, from inside a step with `ctx.client()`.\n- See [Workflows](https://rivet.dev/docs/actors/workflows) for the full workflow API reference including timers, joins, and races.","src/content/docs/docs/workflows.mdx","e67a320bd6af7501","docs/agents/claude",{"id":298,"data":300,"body":304,"filePath":305,"digest":306,"deferredRender":16},{"title":301,"description":302,"skill":303},"Claude Code","Run the Claude Code agent inside a VM with skills, MCP servers, and custom configuration.",false,"## Quick start\n\n\u003CCodeGroup>\n\u003CCodeSnippet file=\"examples/claude/server.ts\" />\n\n\u003CCodeSnippet file=\"examples/claude/client.ts\" title=\"client.ts\" region=\"quickstart\" />\n\u003C/CodeGroup>\n\nRead [Sessions](/docs/sessions) first for session options, streaming events, prompts, and lifecycle management.\n\n## LLM Credentials\n\nSet the relevant variable(s) on the session's `env`, sourced from your server's environment:\n\n- `ANTHROPIC_API_KEY` — Anthropic API key (direct API).\n- `ANTHROPIC_AUTH_TOKEN` — bearer token for proxy / OAuth auth.\n- `ANTHROPIC_BASE_URL` — route through a gateway or proxy endpoint.\n- `ANTHROPIC_MODEL` — override the default model.\n- `CLAUDE_CODE_USE_BEDROCK=1` — use Amazon Bedrock (auth via the AWS credential chain: `AWS_REGION`, `AWS_PROFILE`, …).\n- `CLAUDE_CODE_USE_VERTEX=1` — use Google Vertex AI (auth via Google Cloud credentials).\n\nSee [LLM Credentials](/docs/llm-credentials), and Claude Code's [environment variables](https://code.claude.com/docs/en/env-vars) for the full list.\n\n## Skills\n\nClaude Code discovers [agent skills](https://docs.claude.com/en/docs/claude-code/skills) from `SKILL.md` files under its skills directory.

For the agent-author view (how to opt in and the rules your SDK must follow), see [Software Definition → SDK snapshotting & snapshot-safety](/docs/custom-software/definition). For how sessions work in general, see [Agent Sessions](/docs/architecture/agent-sessions).\n\n## The problem: per-session SDK re-evaluation\n\nWhen a session starts, its agent adapter runs inside a fresh [V8 isolate](/docs/architecture/agent-sessions) and imports the agent SDK (for Pi, `@mariozechner/pi-coding-agent`). Importing a real-world SDK means resolving, loading, compiling, and **evaluating** a large module graph — hundreds of modules running their top-level initialization. That evaluation dominates session-creation latency, and because every session gets a fresh isolate, it is paid *again on every `createSession`*.\n\nThe work is identical every time: the same modules, evaluated to the same post-init heap, only to be thrown away when the session ends. Snapshotting captures that post-init heap once and stamps it into every new isolate.\n\n## How V8 heap snapshots work here\n\nagentOS already boots every guest isolate from a **V8 startup snapshot** of the runtime bridge (the polyfill layer that provides `fetch`, node builtins, the kernel-backed module loader, etc.). A startup snapshot is a serialized image of a V8 heap *after* some code has run; restoring it into a fresh isolate reproduces that heap by deserialization rather than re-execution, and each restore produces an independent context.\n\nAgent SDK snapshotting extends that same mechanism: it evaluates the agent SDK **into the same snapshot context, right after the bridge**, so the captured image contains the bridge *and* the fully-initialized SDK. Restoring it gives a fresh isolate where the SDK is already present — no import, no evaluation.\n\n## Where it sits in the component model\n\nThe [three components](/docs/architecture#the-big-picture) are unchanged. Snapshotting only changes *how* the executor's isolate is seeded:\n\n- **Client.** Builds the SDK bundle at package-build time and passes it to the sidecar as trusted VM configuration (`jsRuntime.snapshotUserlandCode`). It decides which agents opt in.\n- **Sidecar.** Owns the snapshot. It builds the snapshot once, caches it process-wide, and seeds each session's isolate from it. The SDK runs inside the isolate under the same [permission policy](/docs/permissions) as any guest code — snapshotting grants the SDK no extra capability.\n- **Executor.** The agent adapter restores into an isolate where the SDK is already on the global, reads it, and proceeds. It is untrusted guest code as always.\n\n## The pipeline\n\n### 1. Bundle the SDK to one snapshottable unit\n\nThe agent SDK and its transitive dependencies are bundled (esbuild, IIFE) into a single file shipped with the agent package (`dist/sdk-snapshot.js`). The bundle evaluates the SDK and publishes its public API on a well-known global (e.g. `globalThis.__PI_SDK_RUNTIME__`). Node builtins stay external (resolved by the bridge's in-snapshot polyfills); heavy provider SDKs that are only reached via dynamic `import()` stay lazy and load post-restore from the VFS.\n\n### 2. Capture the evaluated SDK into the snapshot\n\nThe sidecar runs the bridge, then the SDK bundle, in one snapshot-creation context, then serializes the heap. The result is a startup blob containing both. Per-session configuration (cwd, model, API keys) is **not** captured — it is injected after restore, so one blob serves every session.\n\n### 3. Cache it process-wide, keyed by content\n\nThe blob is stored in a **sidecar-process-wide cache keyed by `sha256(bridge + bundle)`**. Any change to the bridge or the bundled dependency graph changes the key and triggers exactly one rebuild; an unchanged bundle is a cache hit. This is what makes it **build-once-per-sidecar**: the cache is shared across every VM and session in the process.\n\n### 4. Pre-warm so the first session is warm\n\nBuilding the snapshot is itself the expensive evaluation, just done once. To keep it off the session-create critical path, the sidecar **pre-warms** at VM creation: when a VM is configured with a snapshot bundle, the sidecar builds the blob into the cache *before* the first session is created. The first session then restores from a warm cache like every session after it.\n\n\u003CWarning>\n**Pre-warm and V8 initialization order**\nThe V8 platform must be initialized on a long-lived thread *before* any pre-warm runs. agentOS initializes the embedded runtime on the sidecar's main thread at startup. Initializing V8 lazily on a transient worker thread that then exits corrupts the platform and wedges later isolate creation — so the startup init is load-bearing, not incidental.\n\u003C/Warning>\n\n### 5. Restore a fresh isolate per session\n\nOn `createSession`, the agent's isolate is created from the cached blob. The SDK is already evaluated in the snapshot's default context, and each session gets a **fresh context cloned from it**. The adapter reads the SDK off the global instead of importing it. If no snapshot is configured — or snapshot creation fails — the adapter transparently falls back to the per-session dynamic-import path, so snapshotting never affects correctness, only latency.\n\n## Isolation\n\nEach session leases a **fresh context** cloned from the snapshot's default context. The captured SDK is shared read-only through the blob, but live state is not: a global, a captured-object mutation, or even a built-in prototype change made in one session is **not** observable in another. This is the same isolation guarantee as a non-snapshot session — a fresh isolate per session — and is covered by dedicated tests (a session that mutates `globalThis`, an SDK object, and `Array.prototype`, with a second session from the same snapshot seeing none of it).\n\n## Snapshot-safety: what an SDK must avoid\n\nA startup snapshot can only capture a pure JS heap. The SDK's **module-initialization** code (everything that runs at import time, before any function is called) must not, at top level:\n\n- Create a **native handle** — load a `.node` addon, instantiate WebAssembly, or produce any V8 *External* object (for example an ICU-backed `Intl.Segmenter` singleton). These cannot be serialized and abort snapshot creation.\n- Open an **fd, socket, timer, or worker**, or leave a **pending promise** at the end of evaluation.\n- Read **non-deterministic or per-session state** (`process.env`, cwd, model, `Date.now()`, `Math.random()`, a random UUID) into a module constant — it would be frozen to the build-time value.\n\nReal-world SDKs frequently break these by accident. agentOS makes such an SDK snapshottable with **build-time transforms in the bundle** that defer the offending work to first use (e.g. wrap a module-level native singleton in a lazy proxy, inline a top-level config-file read, convert eager fire-and-forget imports to synchronous module references). Each transform asserts the source shape it expects, so an upstream SDK change surfaces as a build error rather than a silent regression. The full author-facing rules live in the [Software Definition](/docs/custom-software/definition) reference.\n\n## Opt-in, per agent\n\nSnapshotting is **opt-in per agent**, via `agent.snapshot: true` on the [agent software descriptor](/docs/custom-software/definition), and requires the agent package to ship a snapshot-safe `dist/sdk-snapshot.js`. Today only the Pi agent opts in; other agents run the normal per-session import path. An agent qualifies by (1) being snapshot-safe and (2) building the bundle — there is nothing Pi-specific in the runtime mechanism.\n\n\u003CNote>\n**Current trade-off**\nThe bundle is currently delivered inline in the (trusted) VM config, which moves bytes onto VM creation. The intended refinement is to ship the bundle as a build-time blob the sidecar loads from the guest VFS by path, keeping the config small. Either way the snapshot is built once per sidecar and reused across sessions.\n\u003C/Note>","src/content/docs/docs/architecture/agent-sdk-snapshots.mdx","eac9412e8bdd154e","docs/architecture/agent-sessions",{"id":347,"data":349,"body":352,"filePath":353,"digest":354,"deferredRender":16},{"title":350,"description":351,"skill":16},"Agent Sessions","Internals of agent sessions: how a session is created and bound to a VM, how prompts and events flow from client to sidecar to agent adapter and back, the session lifecycle, and where session state lives.","This page is an internals deep-dive on how agent sessions work under the hood. For the usage API (creating sessions, sending prompts, streaming responses, replaying events), see [Sessions](/docs/sessions).\n\nA session is a long-lived conversation with an agent (such as [Pi](https://github.com/mariozechner/pi-coding-agent)) running inside a VM. Where a bare `exec()` / `run()` starts a fresh guest process and returns when it exits, a session keeps an agent process alive across many prompts, streams its output back as events, and persists a transcript that survives sleep/wake cycles. Everything below describes the machinery that makes that possible while keeping the agent inside the same isolation boundary as any other guest.\n\n## Where a session sits in the component model\n\nThe [three components](/docs/architecture#the-big-picture) are unchanged for sessions: a trusted **client**, the trusted **sidecar** that owns the kernel, and the untrusted **executor** that runs guest code. An agent session adds one more layer on the guest side of the boundary:\n\n- **Client.** Calls `createSession`, `sendPrompt`, and the rest of the session API. It never runs the agent itself; it drives the session over the wire protocol.\n- **Sidecar / kernel.** Spawns the agent as a kernel-managed process inside the VM, owns the session's I/O, applies the permission policy on every syscall the agent makes, and persists the transcript.\n- **Agent adapter.** A per-agent-type shim, inside the VM, that translates between the session protocol and the specific agent's native interface. It normalizes the agent's output into the [Agent Communication Protocol (ACP)](/docs/sessions) so every agent type produces the same event shape.\n- **Executor.** The agent process itself plus any tools it spawns. It is untrusted guest code like any other: its file reads, child processes, and network calls all flow through the kernel.\n\nThe key consequence: an agent is not privileged. It is a guest process that happens to be long-lived and conversational. Its capabilities are exactly the VM's [permission policy](/docs/permissions), nothing more.\n\n## Creating a session and binding it to a VM\n\nA session is always created against an existing VM. The client resolves a VM handle (for example `client.vm.getOrCreate([...])`) and calls `createSession(agentType, options)` on it. Under the hood:\n\n1. **The request crosses the wire** (client to sidecar) carrying the agent type and the session options: `env`, `cwd`, `mcpServers`, `additionalInstructions`, and `skipOsInstructions`.\n2. **The kernel boots the VM** if it is not already running, with its bootstrapped virtual filesystem.\n3. **The sidecar selects the agent adapter** for the requested type and spawns the agent as a kernel-managed process inside that VM. Because the VM does not inherit the host `process.env`, the agent only sees the `env` passed in the options (this is why API keys must be supplied explicitly). The process starts in `cwd` (default `/home/agentos`).\n4. **The session is registered** in the VM with a `sessionId`, and the adapter performs its handshake with the agent to discover `capabilities` and `agentInfo`.\n5. **The handle returns** that metadata to the client.\n\nThe session is bound to that VM for its lifetime. The agent process, its working directory, and its persisted transcript all live inside the VM's isolation domain. A VM can host several sessions at once: each gets its own agent process, but they share the one VM's filesystem (see [Multiple sessions](/docs/sessions#multiple-sessions)). Two sessions in two different VMs share nothing, exactly as described in the [isolation model](/docs/architecture).\n\n\u003CNote>MCP servers configured on a session follow the same boundary. A `local` MCP server runs as a child process inside the VM (kernel-managed, gated by the permission policy); a `remote` MCP server is reached over the network, so its traffic flows through the kernel socket table and is subject to the network allowlist.\u003C/Note>\n\n## How a prompt flows: client to agent and back\n\nSending a prompt is a request in one direction with a stream of events flowing back in the other. The lifecycle of a single prompt extends the general [lifecycle of a request](/docs/architecture):\n\n1. **The client calls `sendPrompt(sessionId, text)`.** The request crosses the wire to the sidecar (hop one).\n2. **The sidecar routes it to the session's agent adapter,** which translates the prompt into the agent's native input and writes it to the running agent process.\n3. **The agent works the turn.** As it thinks, calls tools, edits files, and produces output, every action it takes is a guest syscall back into the kernel (hop two): file reads/writes hit the VFS, tool subprocesses are kernel-managed, and network calls go through the socket table under the allowlist.\n4. **The adapter normalizes the agent's output into ACP events.** Each event is assigned a monotonically increasing sequence number, appended to the session's event log, and persisted.\n5. **Events stream back to the client** as `sessionEvent` notifications, carrying the `sessionId` and the ACP `event` (its `method` and `params`). This is why the docs recommend subscribing to `sessionEvent` before calling `sendPrompt`: events emitted early in the turn would otherwise be missed.\n6. **The turn resolves.** When the agent finishes the turn, `sendPrompt` resolves with the reply.\n\n`cancelPrompt(sessionId)` interrupts an in-progress turn: the request crosses to the sidecar, which signals the agent process to stop the current turn through the adapter, leaving the session itself alive for the next prompt.\n\n```\nclient sidecar / kernel agent adapter agent (executor)\n | sendPrompt | | |\n | --------------------> | route to session | |\n | | ---------------------------> | native input ---> |\n | | | | (thinks, calls\n | | \u003C--- syscalls (VFS, procs, sockets) ------------ | tools, edits)\n | | | \u003C-- native output |\n | sessionEvent (ACP) | persist + assign seq | |\n | \u003C------------------- | \u003C-------- ACP events ------- | |\n | ...stream... | | |\n | resolve(reply) | | |\n | \u003C------------------- | | |\n```\n\n## Session lifecycle\n\nA session moves through these states, all driven by client calls over the wire:\n\n- **Active.** Created and bound to a running VM, with a live agent process. Prompts can be sent and events stream back.\n- **Suspended.** When the VM sleeps, the agent process is torn down but the session's persisted transcript remains in storage. `resumeSession(sessionId)` reconnects: the kernel wakes the VM, re-spawns the agent, and rebinds the session so prompts can continue.\n- **Closed.** `closeSession(sessionId)` gracefully shuts down the agent process and releases its in-VM resources, but leaves the persisted transcript intact so history can still be queried.\n- **Destroyed.** `destroySession(sessionId)` removes the session and all of its persisted events. This is irreversible.\n\nBecause the transcript is persisted, closing or suspending a session is not the same as losing it: the event history can be read back later, even when the VM is not running.\n\nRuntime configuration (`setModel`, `setMode`, `setThoughtLevel`) mutates an active session in place by sending the change through the adapter to the live agent, without restarting the session.\n\n## Resuming a suspended session\n\nWhen a VM sleeps the agent process is destroyed, but the session registry and the transcript survive in SQLite. `resumeSession(sessionId)` (or simply prompting a suspended session) rebinds the stable, client-facing `sessionId` to a freshly spawned agent. Resume is **lazy** (it runs on the first prompt to a non-live session) and **capability-driven** (the orchestrator never special-cases an agent by name, only by what it advertises). There are two paths:\n\n- **Native ACP resume (optimization).** If the agent advertises ACP `loadSession`/`resume` and its own store survived on the durable root, the sidecar issues `session/load` and the agent restores its full context itself. The `sessionId` is unchanged.\n- **Universal transcript fallback.** If the agent has no native resume, or its store did not survive, the sidecar reconstructs a Markdown transcript from the recorded events, writes it into the VM (for example `/root/.agentos/threads/\u003CsessionId>.md`), starts a fresh agent, and prefixes the next prompt with a pointer to that file. Because this needs only file-read tools it works for any agent with no per-agent code, at the cost of pointing the agent at the transcript rather than pre-loading it into context.\n\nResume depends on a **durable root filesystem**. The RivetKit actor configures one automatically (its SQLite-backed root), so transcript capture and resume work out of the box. A direct `AgentOs` SDK user on the default in-memory root has no durable store: transcript capture is a no-op and context cannot be restored, so configure a durable root explicitly if you need resume outside the actor.\n\n## Adapter crashes and bounded auto-restart\n\nIf the agent process exits without `closeSession()` — any spontaneous exit, including exit code 0 — the sidecar treats it as a crash, not a lifecycle transition. Crashes are detected both mid-request (the exchange loop observes the process exit) and while idle (the next write to the dead adapter fails). The sidecar logs the exit with its code and a stderr tail, emits an `AcpAgentExitedEvent` to the host (`onAgentExit` in the SDK, `agentCrashed` on the actor), and attempts an **in-place restart, bounded to 3 attempts per session**:\n\n- **Native re-attach only.** The restart relaunches the adapter with the exact parameters of the original launch, re-probes capabilities with a fresh `initialize`, and — if the agent advertises `loadSession`/`resume` — re-attaches the **same `sessionId`** via `session/load`. Clients keep their handle and the session stays active. There is deliberately no `session/new` fallback tier here: a fallback would produce a different live session id that an in-place restart cannot remap transparently. That path belongs to lazy resume (above), which owns the external→live remap.\n- **Eviction otherwise.** If the adapter has no native resume capability, the restart fails, or the budget is exhausted, the session record is evicted — the same teardown as before auto-restart existed. The persisted transcript is untouched, so the actor's lazy resume can still recover the conversation on the next prompt.\n- **The interrupted request still fails.** A prompt in flight when the adapter died is never replayed (the turn may have had side effects); its error names the restart outcome so the caller knows whether a retry will succeed.\n\nEach event carries `{ exitCode, restart, restartCount, maxRestarts }`, where `restart` is `\"restarted\"`, `\"unsupported\"`, `\"failed\"`, or `\"exhausted\"`; only `\"restarted\"` leaves the session usable. See [Debugging](/docs/debugging#agent-crashes-onagentexit) for capturing these from the SDK.\n\n## Where session state lives\n\nSession state spans two tiers:\n\n- **In-memory, while the VM runs.** The running agent process holds the live conversation, and the sidecar keeps the session's recent event log with sequence numbers, the basis for live reconnection: a client tracks the last sequence number it processed and asks for everything after it, so no events are dropped or duplicated across a reconnect.\n- **Persisted in SQLite, independent of the VM.** Every ACP event is written to a SQLite-backed transcript store inside the VM, keyed by `sessionId` and sequence number. This tier survives sleep/wake and VM shutdown. `listPersistedSessions()` and `getSessionEvents(sessionId)` read from it and work even when the VM is not running, which is what makes transcript-history UIs possible without keeping a VM warm.\n\nSee [Replay events](/docs/sessions#replay-events) for replaying a session's persisted events.\n\nThe transcript living inside the VM keeps session state on the same side of the boundary as the agent that produced it: it is part of the VM's isolation domain, not the client's. The client only ever sees it by asking the sidecar for it over the wire.\n\n## Where to go next\n\n- [Sessions](/docs/sessions): the usage API for creating sessions, sending prompts, and replaying events.\n- [Architecture](/docs/architecture): the component model, request lifecycle, and isolation model that sessions build on.\n- [Permissions](/docs/permissions): the policy the kernel enforces on every syscall an agent makes.\n- [Replay events](/docs/sessions#replay-events): in-memory versus persisted event replay.","src/content/docs/docs/architecture/agent-sessions.mdx","6f588d17c4849062","docs/architecture/compiler-toolchain",{"id":355,"data":357,"body":360,"filePath":361,"digest":362,"deferredRender":16},{"title":358,"description":359,"skill":16},"Compiler Toolchain","How agentOS compiles its command suite to WebAssembly: Rust coreutils via cargo and C programs via wasi-sdk, linked against a patched wasi-libc plus the wasi-ext bindings, and how the resulting .wasm files become the guest's commands.","The commands a guest runs through [process execution](/docs/processes), the shell\n(`sh`) and the coreutils behind it, are not native host binaries.

This page\ncovers how that command suite is produced: which toolchains compile it, what it\nlinks against, and how the resulting `.wasm` files become the guest's commands.\n\nFor *why* WASM is a first-class guest and *how* it presents a POSIX surface at\nruntime, see the [WASM VM](/docs/architecture/posix-syscalls) page. This page is the build-side\ncounterpart: it documents the toolchain that emits binaries carrying both\n[the host-import layer and the WASI shim](/docs/architecture/posix-syscalls).\n\n## Target: `wasm32-wasip1`\n\nEverything in the command suite is compiled to a single target,\n`wasm32-wasip1`: the WASI preview 1 ABI on the 32-bit WebAssembly architecture.\nPicking one target for the whole suite means a single libc, a single set of\nhost import declarations, and a single runtime shim can serve every command.\n\nA guest module built for this target expects standard WASI (preopened file\ndescriptors, clocks, randomness, file I/O) plus the extra agentOS import modules\ndescribed below. Both halves are satisfied at runtime by the kernel-backed\nruntime; nothing in a compiled command reaches a real host syscall.\n\n## Two source languages, two compilers\n\nThe suite is heterogeneous: most tools are Rust, some are C. Each language uses\nits own compiler driver, but both emit the same `wasm32-wasip1` ABI and link\nagainst the same sysroot, so the outputs are interchangeable at runtime.\n\n- **Rust coreutils** are built with **`cargo`** targeting `wasm32-wasip1`. Rust's\n standard library already has first-class support for this target, so the\n coreutils crates compile with an ordinary cross-compile invocation.\n- **C programs** are built with the **`wasi-sdk`** toolchain, a packaged\n `clang` plus sysroot tuned for WASI. C tools that have no Rust equivalent (or\n that are easier to carry as upstream C) go through this path.\n\n```bash\n# Rust coreutils\ncargo build --target wasm32-wasip1 --release\n\n# C programs via wasi-sdk, linked against the patched libc + wasi-ext\n$WASI_SDK/bin/clang --target=wasm32-wasip1 \\\n --sysroot=$WASI_SYSROOT \\\n -lwasi-ext \\\n tool.c -o tool.wasm\n```\n\n## What every binary links against\n\nRegardless of source language, each command links against the same two pieces.\nTogether they give a single binary both the standard WASI calls and the agentOS\nprocess / user / network extensions.\n\n- **A patched `wasi-libc`.** The libc is the WASI standard library, modified so\n that the calls a normal command-line program performs resolve against the\n agentOS surface instead of failing or hitting unimplemented stubs. This is the\n same patched libc the [Layer 2 shim](/docs/architecture/posix-syscalls) adapts at runtime; the\n build side and the runtime side are two ends of the same contract.\n- **The `wasi-ext` bindings.** These declare the extra WebAssembly import\n modules (`host_process`, `host_user`, `host_net`, and the small\n `host_sleep_ms` binding) that base WASI cannot express. Linking `wasi-ext`\n into a binary is what lets its libc emit `fork` / `exec`, `getuid` / `getgid`,\n and `connect` / `listen` as ordinary-looking syscalls that the host runtime\n then services through the kernel. See\n [Layer 1: custom host import modules](/docs/architecture/posix-syscalls) for the runtime half.\n\n\u003CNote>\nThe import declarations are compile-time only: linking `wasi-ext` tells the\nmodule *which* host imports to reference, but the calls are still routed through\nthe kernel and gated by the VM's [permission policy](/docs/permissions) at\nruntime. Building against `host_net` does not grant network access.\n\u003C/Note>\n\n## From `.wasm` to a guest command\n\nThe compiler toolchain's product is a set of `.wasm` files, one per command.\nThose files are what the runtime mounts as the guest's executables: when a guest\ninvokes `ls`, `sh`, or any other bundled tool, the kernel resolves the name to\nthe corresponding module, instantiates it with the host imports and the WASI\nshim wired in, and runs it as a [child process](/docs/processes) with real\nprocess, user, and network semantics, all virtualized.\n\nThe same path is open to your own programs. A program you compile for\n`wasm32-wasip1` runs as a guest command exactly like the bundled ones; link the\n`wasi-ext` bindings if it needs processes, users, or sockets, and leave them out\nfor a pure-compute tool. Heavy native binaries that are not yet available as\nWASM belong in a [mounted sandbox](/docs/sandbox) instead.\n\n## Recommendations\n\n- Use the bundled WASM coreutils and `sh` for normal shell workloads; they\n already carry the patched libc and the `wasi-ext` extensions.\n- To ship your own command, compile it for `wasm32-wasip1` with `cargo` (Rust)\n or the `wasi-sdk` `clang` (C), and link `wasi-ext` only if it needs the\n process / user / network host imports.\n- Keep the build and runtime contracts aligned: the patched `wasi-libc` and the\n `wasi-ext` import declarations a binary is compiled against are the same ones\n the [WASM VM](/docs/architecture/posix-syscalls) runtime expects to satisfy.","src/content/docs/docs/architecture/compiler-toolchain.mdx","49ef24cfa33c5d1f","docs/architecture/filesystem",{"id":363,"data":365,"body":367,"filePath":368,"digest":369,"deferredRender":16},{"title":119,"description":366,"skill":16},"Internals of the kernel VFS: the overlay/mount/root engines, how guest fs syscalls are routed and confined, WASM preopens, and mount confinement against symlink and .. escapes.","This page is an internals deep-dive on the **kernel virtual filesystem (VFS)**: how it is layered, how a guest `fs` syscall is routed through it, and how guest I/O is confined to the VM. For the user-facing API (reading, writing, mounting, persistence), see [Filesystem](/docs/filesystem).\n\nThe invariant this whole subsystem exists to uphold: **every guest filesystem operation is serviced by the kernel-owned VFS, never by a real host capability.** There is no host disk reachable from the guest. The VFS presents normal Linux semantics to tools while keeping every byte inside the kernel.\n\n\u003CNote>The security boundary is sidecar to executor. The VFS lives inside the trusted sidecar; the guest in the executor only ever *asks* for a filesystem operation. Confinement is the kernel's job, not the guest's. See the [Security Model](/docs/security-model) for the full threat model.\u003C/Note>\n\n## Where the VFS sits\n\nA guest `fs` call never touches the host. The path is always:\n\n```\nguest fs call (executor)\n -> kernel syscall (crosses sidecar \u003C-> executor boundary)\n -> VFS engine resolves the path\n -> backing store services the operation\n -> result returns to the executor\n```\n\n- The executor holds **no** filesystem capability of its own. It issues a syscall and blocks for the reply.\n- The kernel checks the applied permission policy for the filesystem scope before servicing the request.\n- The VFS resolves the path against the VM's layered engines, then services the operation against the engine that owns that path.\n\nBecause every byte is mediated here, two properties fall out for free: the guest can never reach the real host disk, and one VM's filesystem is never visible to another VM. Isolation is per-VM.\n\n## The VFS engines\n\nThe per-VM filesystem is not a single flat store. It is a tree of **engines**, each responsible for a subtree of the namespace. A path is resolved by walking from the root engine down to whichever engine owns the deepest matching prefix, then handing the remainder of the path to that engine.\n\n- **Root engine.** Owns `/` and the base namespace. Every VM boots with a root filesystem bootstrapped from a snapshot, so the guest starts against a populated POSIX tree (the default working directory is `/home/agentos`).\n- **Overlay engine.** Composes layers so writes land in a writable upper layer while reads fall through to a lower layer. This is how a read-mostly base can be presented as writable to the guest without mutating the shared lower layer.\n- **Mount engine.** Grafts a distinct backing store onto a guest path (a mount point). Below the mount point, operations are routed to that mount's backend instead of the parent engine. This is the mechanism behind in-memory, host-directory, S3, and Google Drive mounts.\n\nResolution is **longest-prefix wins**: if `/mnt/data` is a mount and the guest opens `/mnt/data/file`, the mount engine services it; anything outside `/mnt/data` stays with the parent (root/overlay) engine.\n\n```\n/ \u003C- root engine (bootstrapped from snapshot)\n|- home/user/... \u003C- root / overlay\n|- mnt/\n| |- scratch/... \u003C- mount engine -> in-memory backend\n| |- code/... \u003C- mount engine -> host-directory backend (read-only)\n| \\- data/... \u003C- mount engine -> S3 backend\n\\- ...\n```\n\nThe base layer is in-memory and per-VM; the runtime transparently persists it to backing storage so it survives sleep/wake. Mounts are pluggable: any guest path can be backed by the host, a remote, or a cloud store. See [Mounting filesystems](/docs/filesystem#mounts) for the user-facing config.\n\n## Routing a guest syscall\n\nWhen the guest calls, say, `readFileSync(\"/mnt/data/report.csv\")`:\n\n1. **Permission check.** The kernel checks the installed filesystem policy. The sidecar installs `allow` when the top-level `fs` scope is omitted; an explicit deny rejects the operation with `EACCES` (see [Permissions](/docs/permissions)).\n2. **Engine resolution.** The VFS walks the namespace and selects the engine owning the longest matching prefix (`/mnt/data` -> the S3 mount engine).\n3. **Path normalization and confinement.** The remainder of the path is normalized within the owning engine's root. `.` and `..` segments are resolved *before* the operation reaches the backend, so the request cannot climb above the engine's root.\n4. **Backend operation.** The owning engine's backend services the read/write/stat/etc. against its store (in-memory pages, the persisted base, a host directory, S3, ...).\n5. **Reply.** The result crosses back to the executor, which unblocks.\n\nHost-side APIs (`agent.writeFile`, `agent.readFile`) enter the *same* VFS from the trusted side, which is why the host can seed and read files the guest sees, without ever exposing the real host disk to the guest.\n\n## Mount confinement\n\nA host-backed mount (host directory, S3, ...) comes from trusted config, so its existence, target, and credentials are not attack surface. What *is* in scope is the guest-driven traffic through it: the guest must not be able to use a mounted path to reach bytes outside the mount root. Confinement is enforced by the kernel, on every operation:\n\n- **`..` traversal.** Path segments are normalized relative to the mount root before the backend sees them. A guest path like `/mnt/code/../../etc/passwd` cannot resolve above the mount root; it is clamped to the mount's own subtree (and, above the mount point, handed back to the parent engine, which is itself the kernel VFS, not the host).\n- **Symlinks.** Symlink resolution (`realpath` following) is performed by the kernel against the *virtual* namespace, not the host's. A symlink inside a host-directory mount cannot be used to escape the mount root onto the wider host filesystem; the resolved target is re-confined to the mount root.\n- **Path aliasing / TOCTOU.** Because resolution and confinement happen inside the kernel on each operation, there is no window where the guest resolves a path and the backend later acts on a different one. The guest sees only the mounted subtree, never the wider host filesystem.\n\nMounts for host and remote backends are **read-only by default**; a writable mount must be opted into explicitly. The `readOnly` flag is enforced at the engine, so a write syscall to a read-only mount fails inside the kernel rather than reaching the backend.\n\n\u003CNote>\"Trusted mount, untrusted traffic\": the mount's target is trusted configuration, but the guest drives I/O through it, so confining guest operations to the mount root (`..`, symlink, TOCTOU, path-aliasing) is squarely in scope and enforced by the kernel.\u003C/Note>\n\n## WASM preopens\n\nWASI does not grant a WASM guest an ambient filesystem. Instead, the host hands the module a set of **preopened directories**: capability handles to specific subtrees, and the guest can only reach paths reachable from a preopen.\n\nIn agentOS these preopens are wired to the **same kernel VFS** rather than to host directories:\n\n- A preopen maps a guest-visible path to a VFS subtree. File descriptors derived from it are serviced by the VFS engines above, with the same confinement rules.\n- The WASM guest therefore sees the virtualized filesystem (root snapshot, overlays, mounts) through standard WASI calls, with no host filesystem handle anywhere in the chain.\n- Confinement composes: a preopen rooted at a mount point inherits that mount's `..`/symlink confinement, because resolution still runs through the kernel VFS.\n\nThe result is that WASI filesystem access and the V8/Node `fs` path converge on one virtual filesystem, so both executor flavors get identical isolation and identical Linux semantics.\n\n## Where to go next\n\n- [Filesystem](/docs/filesystem): the user-facing API for reading, writing, mounting, and persistence.\n- [Architecture](/docs/architecture): the components, trust boundary, and kernel-owned syscall paths.\n- [Permissions](/docs/permissions): the filesystem scope the kernel checks on every operation.\n- [Security Model](/docs/security-model): the full trust model and threat boundary.","src/content/docs/docs/architecture/filesystem.mdx","361170781557bcda","docs/architecture/limits-and-observability",{"id":370,"data":372,"body":375,"filePath":376,"digest":377,"deferredRender":16},{"title":373,"description":374,"skill":16},"Limits & Observability","How agentOS bounds resources, applies backpressure, warns before a limit is hit, and surfaces it all to the host.","agentOS runs untrusted, AI-generated code inside disposable VMs. Every resource\nthat code can consume is **bounded by default**, and every bound is designed to\n**warn before it is hit**, **fail with a clear error when it is**, and stay\n**inspectable** from one place. This page explains how the limits, backpressure,\nlogging, and observability pieces fit together across the stack.\n\n## Where limits live\n\nLimits are owned by **secure-exec** (the VM runtime) and **forwarded** by agentOS\n— the agentOS layer does not reimplement enforcement, it exposes the knobs and\nsurfaces the signals.\n\n| Layer | Responsibility |\n| --- | --- |\n| secure-exec kernel | Enforces per-VM resource caps (memory/heap, CPU time, fds, processes, sockets, filesystem bytes, …). |\n| secure-exec sidecar | Owns the bounded queues between the guest, the runtime, and the host; applies backpressure; tracks usage. |\n| agentOS client | Forwards `limits` config to the VM and surfaces limit signals to the caller. |\n\n## Three guarantees for every limit\n\nEvery bound — a resource cap, a bounded queue, a timeout, a payload size —\nfollows the same contract:\n\n1. **Bounded by default.** Nothing is unbounded out of the box. Memory is capped\n at ~128 MiB per isolate (Cloudflare Workers parity), CPU is bounded, and every\n queue has a fixed capacity. Operators may *raise* a cap, but never get an\n unbounded default.\n2. **Warn on approach.** As usage crosses a threshold (default **≥80%** of\n capacity), a structured warning is emitted — once per crossing, re-armed only\n after it drains back below 50% (hysteresis), so a busy limit logs once, not on\n every operation.\n3. **Clear, typed error on breach.** Exceeding a limit produces an error that\n names the limit, the observed-vs-cap value, and the config path to raise it —\n never a bare `EAGAIN`, a silent drop, or a crash.\n\n## Backpressure, not catastrophe\n\nThe path from guest code to the host is a **chain of bounded queues**: the V8\nruntime → a per-session frame channel → the V8→host event channel → the sidecar\nstdout frame queue → the host. When a queue fills (a slow host consumer, a chatty\ntool turn), the producer **blocks until the consumer drains a slot** — clean\nbackpressure that flows all the way back to the guest. A full queue never\ndestroys the session, silently drops data, or crashes the sidecar; a genuinely\ndead consumer surfaces as a typed terminal error instead.\n\nBuffer capacities are sized so that *transient* bursts are absorbed without ever\nengaging backpressure; backpressure is the safety net for a genuinely stuck\nconsumer, not a normal-operation event.\n\n## The limit registry\n\nAll bounded limits register with a single in-process **limit registry**. Each\nregistered limit tracks its live depth, high-water mark, and capacity, and emits\nthe near-capacity warning described above. This gives the runtime one place to\nanswer two questions:\n\n- *Is a limit about to be hit?* — the registry fires the approach warning.\n- *What is the current usage of everything?* — a registry snapshot lists every\n limit's depth / high-water / capacity / fill-percent for debugging.\n\nA CI audit fails the build if any limit-shaped constant is not classified and —\nfor operator-tunable ones — wired to a config field, so \"is everything bounded\nand config-wired?\" is verified mechanically rather than by review.\n\n## Logging & host visibility\n\nsecure-exec logs to **stderr** (never stdout — stdout is the framed wire\nprotocol). The default level is `WARN`, tunable with the `AGENTOS_LOG`\nenvironment variable (`error` to quiet, `debug` for per-limit usage snapshots).\nNear-limit warnings and backpressure events therefore show up in the sidecar's\nstderr stream, which agentOS forwards to the host.\n\nThe limit registry also exposes a structured **warning sink**: a callback that\nfires on the same edge as the log, carrying `{ name, category, observed,\ncapacity, fillPercent }`. This is the foundation for host-facing limit\nobservability — a structured \"a limit is approaching capacity\" signal rather than\na parsed log line.\n\n## See also\n\n- [Resource Limits](/docs/resource-limits) — the full `limits` config surface.\n- [Processes](/docs/architecture/processes) and [Sessions & Persistence](/docs/architecture/sessions-persistence) — the layers the queue chain runs through.","src/content/docs/docs/architecture/limits-and-observability.mdx","451a3f1e63bd8857","docs/architecture/networking",{"id":378,"data":380,"body":383,"filePath":384,"digest":385,"deferredRender":16},{"title":381,"description":382,"skill":16},"Networking","How the kernel socket table works: a single VM-local transport that carries host, JavaScript, and WASM traffic, where fetch / net / dns route through it, how egress policy and loopback confinement are enforced, and how preview URLs are served.","This is the internals view of agentOS networking: the kernel socket table, the layers a request crosses, and where policy is enforced. For the user-facing API (`vmFetch`, preview URLs, the confinement model from a caller's perspective), see [Networking & Previews](/docs/networking). For the trust boundary this all sits inside, see [Architecture](/docs/architecture).\n\nThe governing rule is that there is exactly **one authoritative transport for everything VM-local**: the kernel socket table. No part of guest networking opens a real host socket on its own. Guest `fetch()`, `node:http`, `node:net`, WASM TCP clients and servers, and host-into-guest requests (`vmFetch` / `rt.fetch`) all target the same listener table.\n\n## The kernel socket table\n\nThe socket table is the floor of the stack and the only component that actually moves bytes between two in-VM endpoints. It is per VM, so two VMs never share a listener or a connection.\n\n- It exposes POSIX-style primitives: `socket_create`, `socket_bind_inet`, `socket_connect_inet_loopback`, `socket_read`, `socket_write`, `poll_targets`.\n- Every call is **owner-checked** (the calling process must own the descriptor) and **resource-accounted** against the VM's limits.\n- Failures return correct POSIX errnos (`ECONNREFUSED`, `EACCES`, …) so guest code branches the way it would on real Linux.\n- Connecting pairs two in-VM sockets and shuttles bytes between them. No host networking happens at this layer.\n\nBecause every server is a kernel TCP listener, a client never needs to know whether the server it is talking to is JS, WASM, raw TCP, or HTTP. HTTP is layered on top of kernel TCP bytes, so every listener lives in the one table and is reachable identically.\n\n\u003CNote>An earlier design carried two listener models at once: stream-mode listeners (`net.createServer`, WASM) on real kernel TCP sockets, and object-mode HTTP listeners (`http.createServer`) on a separate table that exchanged JSON request/response objects over stream events. A second guest process could not reach the object-mode table reliably, because the client expected byte-stream TCP semantics while the server only spoke object-mode dispatch. The current architecture removes the second model: everything is one socket table.\u003C/Note>\n\n## The four layers\n\nA request passes through four layers. Only the top and bottom understand HTTP; the middle two move bytes and enforce policy.\n\n| Layer | Role | Trust | Lives in |\n| --- | --- | --- | --- |\n| 4 · Guest bridge | `node:http` / `node:net` / `fetch` / undici shim | untrusted (V8 isolate) | `crates/execution/assets/v8-bridge.source.js` |\n| 3 · Sync-RPC dispatch | routes `net.connect`, `net.http_request`, `net.listen`, … | trusted | `crates/sidecar/src/service.rs` |\n| 2 · Execution & enforcement | listener state, host fetch client, permission checks | trusted (TCB) | `crates/sidecar/src/execution.rs` |\n| 1 · Kernel socket table | `bind` / `listen` / `connect` / `read` / `write`, loopback routing | trusted (TCB floor) | `crates/kernel/src/socket_table.rs`, `kernel.rs` |\n\n### Layer 1: kernel socket table\n\n`crates/kernel/src/kernel.rs` exposes the primitives above. Loopback routing is the heart of VM-local networking: `socket_connect_inet_loopback` only succeeds against a socket that is actually bound and listening in the same VM's table; otherwise it returns `ECONNREFUSED`. Resource-limit checks run before the two sockets are paired.\n\n### Layer 2: sidecar execution (enforcement point / TCB)\n\n`crates/sidecar/src/execution.rs` is where policy is applied. Two roles matter for networking:\n\n- **Listener state.** `build_javascript_socket_path_context` walks every active process and records what is listening on which port, including a map of HTTP loopback targets keyed by `(family, port)`. This is the source of truth a connect consults to learn that, say, \"port 3000 is an HTTP server owned by process X, server Y.\"\n- **Host fetch client.** When the host calls `vmFetch` / `rt.fetch()`, the sidecar resolves the target to a VM-owned kernel listener, opens its own kernel socket, connects over loopback, and speaks HTTP/1.1 to the guest server. This is the only HTTP client that lives in the sidecar (the host has no guest isolate to do framing for it).\n\n### Layer 3: sync-RPC dispatch\n\n`crates/sidecar/src/service.rs` routes the bridge calls guest code makes. The guest-to-guest loopback HTTP path lands here as `net.http_request`. It is the most security-sensitive RPC, so it is guarded in order:\n\n1. The host must be a loopback address.\n2. The applied network policy must permit the operation.\n3. The requested `(process_id, server_id)` must match a listener that is currently live.\n\nThat last check stops a guest from forging a target to reach a process it should not.\n\n### Layer 4: guest bridge\n\n`crates/execution/assets/v8-bridge.source.js` is the Node-compatibility shim inside the untrusted V8 isolate. It presents `node:http`, `node:net`, `fetch`, and undici to guest code and translates them into Layer 3 bridge calls. `http.createServer()` is implemented on top of `net.Server`: each accepted byte socket is parsed as HTTP and dispatched to the guest's request handler.\n\n## How fetch, net, and dns route through it\n\n- **`node:net` (raw TCP).** `net.connect` / `net.createServer` map directly onto kernel `connect` / `bind` + `listen`. The bytes are the payload; no framing is added.\n- **`node:http` and `fetch`.** A guest HTTP server is a `net.Server` whose accepted sockets are HTTP-parsed in the bridge. A guest HTTP client runs undici over a kernel-backed dispatcher (or a raw serializer for the loopback fast path). Either way the bytes travel as kernel TCP.\n- **DNS.** Name resolution is serviced by the kernel resolver, not the host. Outbound connections that leave the VM resolve through it, and the resolved addresses are then filtered by the egress allowlist (see below). DNS pinning ties the connection to the address that was checked, closing the resolve-then-reconnect TOCTOU gap.\n\n### Where HTTP meets TCP\n\nThere is no shared HTTP/TCP translation module. Because the wire between every endpoint is raw TCP bytes through the kernel, HTTP is framed and deframed **at each edge that speaks HTTP**. The kernel (Layer 1) and the sidecar routing (Layer 2) never parse HTTP. There are three independent codecs, one per kind of endpoint:\n\n| Endpoint | Lives in | Encode / decode |\n| --- | --- | --- |\n| Guest HTTP server | guest bridge | `parseLoopbackRequestBuffer` (bytes to object), `serializeLoopbackResponse` (object to bytes), wired per accepted socket by `attachHttpServerSocket` |\n| Guest HTTP client | guest bridge | undici over a kernel-backed dispatcher, or `serializeRawHttpRequest` + `waitForRawHttpResponse` |\n| Host fetch client | sidecar execution | `serialize_kernel_http_fetch_request` (request to bytes), `parse_kernel_http_fetch_response` (bytes to JSON) |\n\nA WASM HTTP server or client does its own framing in guest code (reading the request line, writing a response with standard C socket calls). The kernel does not help it; it is just bytes, the same as for the JS endpoints.\n\n## Data flows\n\n- **Host to guest (`vmFetch` / `rt.fetch`).** The sidecar resolves the port to a VM-owned kernel listener, opens a sidecar-owned kernel socket, connects over loopback, serializes the request bytes, drives the target process forward so it can accept and respond, then parses the response bytes back into the host response object. It is **fail-closed**: no DNS, no external networking, no host-loopback fallback. If no VM-owned listener exists, it returns a missing-listener error.\n- **Guest to guest.** `net.connect` goes through the sidecar, which returns a loopback HTTP target handle. The guest sends the request through `net.http_request`, which dispatches into the target process's request handler. Cross-process loopback passes through the enforcement point rather than taking an in-isolate shortcut.\n- **Cross-runtime (JS and WASM, either direction).** Client and server connect through a kernel loopback socket pair and exchange raw bytes. JS to WASM, WASM to JS, and WASM to WASM all use the same path; only the side that runs the HTTP codec differs.\n- **Guest outbound to host or external.** Connections that do not target a VM-owned listener take the external network path: permission checks, DNS pinning, then a real host `TcpStream`. Reaching a host loopback port still requires an explicit loopback exemption entry.\n\n## Egress policy and loopback confinement\n\nGuest networking is confined by three distinct controls plus the loopback-only default. The permission policy and limits are **trusted configuration**; the guest executor is the **untrusted subject** they bind.\n\n### Loopback-only by default\n\nGuest listeners are reachable only over loopback (`127.0.0.1` / `::1`) inside the VM.\n\n- Binding to `0.0.0.0` or `::` does not widen this: the kernel normalizes the unspecified address down to loopback, so the listener still answers only on loopback.\n- A connection that originates outside the loopback interface and targets a port the VM does not own is refused with `EACCES`, noting the port is not exempt.\n- This confinement is independent of the permission policy. Even with the network allowed, a guest server stays loopback-only unless its port is explicitly exempted.\n\n### Three stacked controls\n\nThese are often conflated but are separate. They stack, and a request must pass every one that applies:\n\n1. **Permission policy** (`network.listen` / `network.connect`). Decides whether the guest may open a listener or initiate an outbound connection at all. A blocked operation fails with `blocked by network.listen policy` or `blocked by network.connect policy`.\n2. **Loopback confinement.** Decides who may reach an already-permitted guest listener. By default only loopback inside the VM; a per-port exemption loosens it.\n3. **DNS / egress allowlist.** Constrains where permitted outbound connections may go. The kernel filters resolved addresses, blocking outbound access to restricted ranges, so an allowed `connect` can still be refused by destination.\n\nThe per-port loopback exemption belongs to layer 2 only. It is a trusted, per-port whitelist that *loosens* the default loopback confinement (for example, exposing an in-VM dev server beyond loopback). It is not an egress control and grants no outbound reach; layers 1 and 3 still apply. It is configured with `loopbackExemptPorts`, a list of ports that are exempt from the SSRF checks at layer 2; each listed port is reachable from outside the loopback interface, while the permission policy and egress allowlist continue to apply.\n\n### Trust and ownership\n\nEvery guest connect, listen, read, and write passes through sidecar ownership and kernel owner checks. Guest-to-guest loopback is allowed only when the destination is a VM-owned listener and the applied network policy permits the connect. Host-loopback access from guest code is separate and still requires a loopback exemption plus the applied network policy. Long-lived waits must not block the sync-RPC path, so the stack uses stream events, bounded polling, and kernel socket waits with explicit timeouts.\n\n\u003CNote>Host-to-guest requests bypass egress, not the table. `vmFetch` / `rt.fetch` terminate at the guest's loopback listener and never leave the VM, so they work even when guest egress (layer 3) or outbound `connect` (layer 1) is denied. They are host control-plane traffic, not guest egress, and only ever reach VM-owned listeners, while still going through the same kernel socket table as everything else.\u003C/Note>\n\n## Preview URLs\n\nA preview URL is port forwarding for a VM service: a time-limited, signed, publicly reachable URL that proxies HTTP to a port inside the VM. Mechanically it reuses the host-to-guest path:\n\n- A signed token is minted for a `(VM, port)` pair with an expiration, capped by `preview.maxExpiresInSeconds`. Tokens are stored in SQLite, survive sleep/wake cycles, and expired ones are cleaned up automatically.\n- An incoming request to the preview path is authenticated against the token, then proxied into the VM exactly like `vmFetch`: resolve the port to a VM-owned kernel listener, connect over loopback, frame HTTP/1.1, drive the target process, and stream the response back. The same fail-closed, VM-owned-listener-only rules apply.\n- CORS is enabled so browsers can reach preview URLs from any origin.\n- Revocation (`expireSignedPreviewUrl`) invalidates the token immediately, after which the proxy refuses the request before touching the socket table.\n\nBecause previews ride the host fetch path, they are subject to loopback confinement at the kernel but **not** to the guest egress allowlist: the request enters the listener from the host side and never becomes guest outbound traffic.\n\n## Where to go next\n\n- [Networking & Previews](/docs/networking): the `vmFetch` and preview URL API, with usage examples.\n- [Architecture](/docs/architecture): the client / sidecar / executor trust boundary this stack lives inside.\n- [Security Model](/docs/security-model): the full in-scope and out-of-scope threat model.","src/content/docs/docs/architecture/networking.mdx","9a3a667862c77ad4","docs/architecture/packages-and-command-resolution",{"id":386,"data":388,"body":391,"filePath":392,"digest":393,"deferredRender":16},{"title":389,"description":390,"skill":16},"Packages & Command Resolution","How software is packaged, linked, resolved, and executed in an agentOS VM: a package is a directory, resolution is a $PATH walk, and a file's header picks its runtime.","How a command name becomes a running program, and how the software that provides it\nis packaged and linked.

The `/opt/agentos/\u003Cname>/\u003Cversion>/` tree below, with its `bin/` symlink farm,\nis what the runtime **projects** from that package when it mounts it:\n\n```\n/opt/agentos/\u003Cname>/\u003Cversion>/\n├── package.json # name, version, and the \"bin\" map (command → entry file)\n├── agentos-package.json # agentOS metadata: name, optional agent block, provides\n├── bin/ # symlinks the PROJECTION builds from package.json \"bin\"\n│ ├── ls → ../libexec/coreutils # → multicall blob\n│ └── vdir → ../libexec/coreutils # an \"alias\" is just another symlink\n├── libexec/coreutils # helpers run by other programs, never on $PATH\n├── node_modules/ | lib/ # support payload (a JS CLI's flat, self-contained closure)\n└── share/man/man1/ls.1 # man pages and other FHS content\n/opt/agentos/\u003Cname>/current → \u003Cversion> # version pointer; upgrade re-points it (atomic rename)\n```\n\n| Path | Contents |\n|---|---|\n| `package.json` | `name`, `version`, and a `bin` map (command → entry file). |\n| `agentos-package.json` | agentOS metadata the sidecar reads on mount: `name`, an optional `agent` block, and any `provides` (files/env). Generated for command/WASM packages; carries the `agent` block for agents. |\n| `bin/` | Command symlinks the projection builds from `package.json` `bin`; each basename is the command name. (Not part of the shipped package — npm can't carry symlinks.) |\n| `libexec/` | Helpers invoked by other programs, never on `$PATH` (e.g. a multicall blob). |\n| `node_modules/`, `lib/` | Non-executable payload — bundled deps and assets. |\n| `share/` | FHS data — `share/man/man\u003Cn>/*`, etc. |\n| `current` | Symlink `→ \u003Cversion>`; switching versions is one atomic rename. |\n\n```jsonc\n// package.json — commands come from \"bin\"; an agent's ACP entrypoint is just one of them\n{ \"name\": \"pi\", \"version\": \"0.60.0\", \"bin\": { \"pi-acp\": \"dist/acp.js\" } }\n```\n\nA directory is a **valid package** when:\n\n- **Commands come from `package.json` `bin`** (command → a real entry file), and each entry\n **dispatches by header** — a magic number or `#!` shebang, no `.wasm`/`.js` extension or\n `runtime`/`type` field; a headerless entry is `ENOEXEC`. The package ships **no symlinks**\n (npm-safe); the runtime builds the `bin/` farm under `/opt/agentos` itself.\n- **Aliases are symlinks** in the projected `bin/` farm — several names for one program (or a\n multicall blob); `argv[0]` is the invoked name.\n- **It is self-contained** — every import/require/asset resolves inside the package; nothing\n comes from a host `node_modules`, pnpm store, or workspace at runtime\n ([packaging](/docs/custom-software/definition) flattens/bundles deps in).\n- **Minimal metadata** — `package.json` carries only the command set (`bin`) and `version`; there\n is no command list beyond `bin`, no permission tiers (the [VM policy](#confinement--trust)\n governs every command), and no dependency list. A small **`agentos-package.json`** alongside it\n holds the agentOS-specific fields the sidecar reads when it mounts the package — the `name`, an\n optional `agent` block, and any `provides` (files/env). The client never carries this on the\n wire; it forwards only the package directory.\n\n## Linking\n\nLinking is creating the `bin/` symlinks in a `$PATH` directory. agentOS follows Homebrew:\n`/opt/agentos/\u003Cname>` is the cellar, and every command is symlinked into one managed prefix,\n**`/opt/agentos/bin`**, which is on `$PATH`. The standard dirs (`/usr/bin`, `/usr/local/bin`,\n`/bin`) stay ordinary writable Linux dirs — agentOS never writes to them.\n\n\u003Csvg viewBox=\"0 0 760 150\" xmlns=\"http://www.w3.org/2000/svg\" role=\"img\" aria-label=\"PATH search order, left to right, first match wins\" style=\"width:100%;max-width:720px;height:auto;font-family:system-ui,sans-serif\">\n \u003Cdefs>\n \u003Cmarker id=\"pcr-ah2\" viewBox=\"0 0 10 10\" refX=\"8.5\" refY=\"5\" markerWidth=\"7\" markerHeight=\"7\" orient=\"auto\">\n \u003Cpath d=\"M0 0 L10 5 L0 10 z\" fill=\"#94a3b8\"/>\n \u003C/marker>\n \u003C/defs>\n \u003Ctext x=\"16\" y=\"20\" font-size=\"12\" fill=\"#0f172a\">Searched left → right — first match wins (left shadows right)\u003C/text>\n \u003Cline x1=\"16\" y1=\"33\" x2=\"744\" y2=\"33\" stroke=\"#cbd5e1\" stroke-width=\"1.2\" marker-end=\"url(#pcr-ah2)\"/>\n \u003Crect x=\"16\" y=\"50\" width=\"99\" height=\"44\" rx=\"6\" fill=\"#f8fafc\" stroke=\"#cbd5e1\" stroke-width=\"1.3\"/>\n \u003Ctext x=\"65.5\" y=\"76\" text-anchor=\"middle\" font-size=\"9\" font-family=\"ui-monospace,monospace\" fill=\"#334155\">/usr/local/sbin\u003C/text>\n \u003Crect x=\"121\" y=\"50\" width=\"99\" height=\"44\" rx=\"6\" fill=\"#f8fafc\" stroke=\"#cbd5e1\" stroke-width=\"1.3\"/>\n \u003Ctext x=\"170.5\" y=\"76\" text-anchor=\"middle\" font-size=\"9\" font-family=\"ui-monospace,monospace\" fill=\"#334155\">/usr/local/bin\u003C/text>\n \u003Crect x=\"226\" y=\"50\" width=\"99\" height=\"44\" rx=\"6\" fill=\"#eef2ff\" stroke=\"#6366f1\" stroke-width=\"2\"/>\n \u003Ctext x=\"275.5\" y=\"76\" text-anchor=\"middle\" font-size=\"9\" font-family=\"ui-monospace,monospace\" fill=\"#3730a3\">/opt/agentos/bin\u003C/text>\n \u003Crect x=\"331\" y=\"50\" width=\"99\" height=\"44\" rx=\"6\" fill=\"#f8fafc\" stroke=\"#cbd5e1\" stroke-width=\"1.3\"/>\n \u003Ctext x=\"380.5\" y=\"76\" text-anchor=\"middle\" font-size=\"9\" font-family=\"ui-monospace,monospace\" fill=\"#334155\">/usr/sbin\u003C/text>\n \u003Crect x=\"436\" y=\"50\" width=\"99\" height=\"44\" rx=\"6\" fill=\"#f8fafc\" stroke=\"#cbd5e1\" stroke-width=\"1.3\"/>\n \u003Ctext x=\"485.5\" y=\"76\" text-anchor=\"middle\" font-size=\"9\" font-family=\"ui-monospace,monospace\" fill=\"#334155\">/usr/bin\u003C/text>\n \u003Crect x=\"541\" y=\"50\" width=\"99\" height=\"44\" rx=\"6\" fill=\"#f8fafc\" stroke=\"#cbd5e1\" stroke-width=\"1.3\"/>\n \u003Ctext x=\"590.5\" y=\"76\" text-anchor=\"middle\" font-size=\"9\" font-family=\"ui-monospace,monospace\" fill=\"#334155\">/sbin\u003C/text>\n \u003Crect x=\"646\" y=\"50\" width=\"99\" height=\"44\" rx=\"6\" fill=\"#f8fafc\" stroke=\"#cbd5e1\" stroke-width=\"1.3\"/>\n \u003Ctext x=\"695.5\" y=\"76\" text-anchor=\"middle\" font-size=\"9\" font-family=\"ui-monospace,monospace\" fill=\"#334155\">/bin\u003C/text>\n \u003Ctext x=\"16\" y=\"130\" font-size=\"11\" fill=\"#475569\">agentOS links into \u003Ctspan font-family=\"ui-monospace,monospace\" fill=\"#4338ca\">/opt/agentos/bin\u003C/tspan>; the rest are ordinary writable Linux dirs — drop a binary in \u003Ctspan font-family=\"ui-monospace,monospace\" fill=\"#4338ca\">/usr/local/bin\u003C/tspan> to shadow an agentOS tool.\u003C/text>\n\u003C/svg>\n\n| Software | Stored | Linked into |\n|---|---|---|\n| Base, mounted, and runtime-installed agentOS software | `/opt/agentos/\u003Cpkg>/\u003Cver>` (or the mount) | `/opt/agentos/bin` |\n| The user's own files | wherever they put them | `/usr/local/bin`, `/usr/bin`, … (normal) |\n\n- **Base & mounts** link into `/opt/agentos/bin` in a **read-only layer** projected from the\n host and shared across VMs — the symlinks are real but cost nothing per boot.

A snapshotted/persistent volume keeps runtime installs and links across restart; an\nephemeral one drops them on teardown. There is no package-specific persistence mechanism.\n\n\u003CWarning>\nPersisting a layer an untrusted guest can write to also persists whatever the guest linked\nthere. Treat a guest-writable `/usr/local/bin` as guest-controlled on restore (see\n[Confinement & trust](#confinement--trust)).\n\u003C/Warning>\n\n## Execution dispatch (binfmt)\n\nA resolved file's leading bytes are read into a fixed buffer and dispatched like the Linux\nkernel's binary-format handlers. The command's **name plays no part** — `python3`, `node`,\nand `pi` are runtimes only by virtue of their files' headers.\n\n| Header | Result |\n|---|---|\n| `#!` at bytes 0–1 (`binfmt_script`) | the interpreter named on the line |\n| `\\0asm` (`00 61 73 6d`) | WebAssembly runtime |\n| `\\x7fELF` / Mach-O / PE | **`ENOEXEC`** — foreign binary format, no native-arch handler |\n| anything else | `ENOEXEC` (no implicit `/bin/sh` fallback here) |\n\nShebang handling matches `binfmt_script`:\n\n- The interpreter path is **literal and absolute** — not `$PATH`-searched. `#!/usr/bin/env node`\n works only because `/usr/bin/env` looks up its argument.\n- At most **one** argument follows, **not** whitespace-split (`#!/usr/bin/env node --flag` passes\n `node --flag` as a single arg).\n- The header read is bounded to a fixed buffer (`BINPRM_BUF_SIZE`); a longer line truncates.\n Interpreter chaining is depth-bounded (`ELOOP`); a missing interpreter is **`ENOENT`**, not `ENOEXEC`.\n\n\u003CNote>\n**Shell fallback.** On `ENOEXEC`, a POSIX shell re-runs a headerless script via `/bin/sh`. That\nretry lives in the shell ([agentos-shell](/docs/architecture/processes)), not the dispatcher,\nwhich stays strictly `binfmt`-faithful.\n\u003C/Note>\n\n### Multicall (busybox-style)\n\n`bin/ls → ../libexec/coreutils` resolves at open to the shared `coreutils` blob. `argv[0]` is\nthe caller's value **verbatim** (`\"ls\"`) — never derived from the symlink — and the blob selects\nits applet with `basename(argv[0])`, like busybox. Always invoke via the `bin/` name; calling the\nblob by its own path yields an `argv[0]` that selects no applet.\n\n## Command resolution\n\nA `$PATH` walk over the [VFS](/docs/architecture/filesystem), full Linux semantics:\n\n- A name **containing `/`** bypasses `$PATH` and resolves directly (relative to cwd, or absolute).\n- Otherwise each `:`-separated dir is searched in order; the first **executable** regular file\n wins (execute bit required — a non-executable match yields `EACCES`). Left shadows right.\n- An **empty `$PATH` element** (leading/trailing/`::`) means the **current working directory** —\n the POSIX footgun, kept for fidelity.\n- Matches are real VFS files/symlinks — `ls -l`-able, `stat`-able, removable, replaceable. The\n filesystem is authoritative; there is no resolution cache to grow stale.\n\n## The `agentos-software` CLI\n\n```\nagentos-software link \u003Cpath>\n```\n\n- `\u003Cpath>` is a package directory or a node module directory (its `package.json` `bin` map is\n the command list).\n- It brokers a request to the sidecar, which owns the filesystem; the CLI has no privilege of\n its own.\n- Linked names are validated (no `/`, `..`, control chars, overlong names), and for a\n guest-supplied package each symlink target must resolve inside the package root.\n\n## Confinement & trust\n\nEvery process runs under the VM's single [permission policy](/docs/security-model) — like a\nLinux process running with its user/namespace/container privileges, not privileges declared by\nthe binary. A package cannot grant itself permissions. The [trust boundary](/docs/security-model)\nis the sidecar (trusted) vs. the guest (untrusted):\n\n- **Linking changes discoverability, not privilege** — the policy is enforced at spawn,\n regardless of how a command was found.\n- **Shadowing is allowed, Linux-style** — a guest may drop a `node`/`ls` into a writable `$PATH`\n dir; trusted in-VM components defend by invoking tools via **absolute paths** (or a `$PATH`\n that excludes guest-writable dirs). The shadowing binary still runs only under the VM policy.\n- **Guest env is sanitized** like a privileged exec — `LD_*`, `DYLD_*`, `NODE_OPTIONS`, `PATH`,\n `BASH_ENV`, `*PRELOAD` are stripped, as glibc does under `AT_SECURE`.\n- **Trusted vs. guest packages** — symlink-escape checks apply only to guest-writable runtime packages.\n- **Bounded** — the runtime link count is bounded; it warns on approach and fails with a typed\n error naming the limit (see [Limits & Observability](/docs/architecture/limits-and-observability)).\n\n## See also\n\n- [Software Definition](/docs/custom-software/definition) — the host API that produces these packages.\n- [Processes](/docs/architecture/processes) — the JavaScript, WebAssembly, and Python runtimes.\n- [Filesystem](/docs/architecture/filesystem) — the VFS, layers, and persistence.\n- [Security Model](/docs/security-model) — the trust boundary and VM permission policy.","src/content/docs/docs/architecture/packages-and-command-resolution.mdx","de3879554bd53da6","docs/architecture/posix-syscalls",{"id":394,"data":396,"body":399,"filePath":400,"digest":401,"deferredRender":16},{"title":397,"description":398,"skill":16},"POSIX Syscalls","How agentOS extends WASI in two layers so WebAssembly guests behave like normal POSIX programs on top of the kernel.","Not everything inside an agentOS VM is JavaScript. The shell (`sh`) and the\ncoreutils behind [process execution](/docs/processes) ship as WebAssembly\nbinaries, and you can run your own WASM programs too.

These bindings live\nin the `wasi-ext` crate and cover three areas:\n\n- **`host_process`**: process management. Spawn a child process (argv, env, inherited stdio fds, working directory), wait for a child to exit, and related file-descriptor operations. This is what gives a WASM `sh` real [child process](/docs/processes) semantics; spawns go through the kernel process table.\n- **`host_user`**: user and group identity (uid, gid, user info). Base WASI has no concept of a user; this lets tools that call `getuid` / `getgid` see the VM's virtualized identity.\n- **`host_net`**: TCP sockets (connect, listen, send, receive) through the kernel socket table, gated by the same [network permission policy](/docs/networking) as everything else. Base WASI has no general socket API.\n\nA small `host_sleep_ms` binding provides blocking sleep. Together these let a\nguest compiled for `wasip1` behave as if it had a process model, user identity,\nand a network, all virtualized.\n\n```c\n// Imported from the host runtime, declared by the wasi-ext bindings.\n// Guest libc calls these as if they were ordinary syscalls.\n__attribute__((import_module(\"host_process\"), import_name(\"proc_spawn\")))\nint host_proc_spawn(const char *argv, const char *envp, int cwd_fd);\n\n// getuid returns an errno; the uid is written through the out-pointer.\n__attribute__((import_module(\"host_user\"), import_name(\"getuid\")))\nint host_getuid(unsigned int *ret_uid);\n\n__attribute__((import_module(\"host_net\"), import_name(\"net_connect\")))\nint host_net_connect(int fd, const char *addr, int addr_len);\n```\n\n## Layer 2: the kernel-backed WASI shim\n\nThe second layer adapts the standard WASI calls themselves so that programs\nbuilt against a normal libc behave correctly inside the VM. The embedded shim:\n\n- **Routes stdio through the kernel.** `fd_read` / `fd_write` on the standard descriptors go through the kernel stdio bridge rather than host file descriptors, so output stays inside the VM and honors PTYs and redirection.\n- **Fills in libc expectations.** For example `fcntl(F_SETFL)` is serviced via `fd_fdstat_set_flags`, so flag changes that libc performs do not fail.\n- **Mirrors mounts as preopens.** The preopen table reflects the VM's guest path mappings, so mounted directories are visible to WASM path resolution exactly as they are to JS and to `node:fs`.\n- **Enforces read-only tiers.** `path_open` rejects create / truncate / write flags on read-only mounts while still allowing non-mutating opens (directory traversal, `O_DIRECTORY`), so read-only mounts stay read-only without breaking `find`, `ls`, and friends.\n- **Confines paths to their mount.** Targets are resolved beneath the specific preopen's root, so `..` segments cannot escape one mount into a sibling mount or a host path.\n\n```\nfd_read(0) -> kernel stdio bridge (not a host fd)\nfcntl(fd, F_SETFL) -> fd_fdstat_set_flags (libc flag changes succeed)\npath_open(\"/data/x\") -> resolved under the /data preopen root\npath_open(..O_CREAT) -> rejected on a read-only mount\npath_open(\"../../etc\")-> stays inside the mount; cannot escape\n```","src/content/docs/docs/architecture/posix-syscalls.mdx","afdc817a0338ca3a","docs/architecture/processes",{"id":402,"data":404,"body":407,"filePath":408,"digest":409,"deferredRender":16},{"title":405,"description":406,"skill":16},"Processes","Internals of the kernel process model: the virtual process table, how spawns are serviced, stdio bridging, PTYs, and how WASM sh and coreutils map onto it.","This page is an internals deep-dive on the kernel's **process model**: the data\nstructures and syscall paths behind every guest process. For the client-facing\nAPI (`exec`, `spawn`, `openShell`, lifecycle, and the flat `allProcesses`\nsnapshot), see\n[Processes & Shell](/docs/processes). For the surrounding component and trust\nmodel, see [Architecture](/docs/architecture).\n\nTwo invariants frame everything below:\n\n- **No real host process is ever spawned for guest work.** Every guest process is an entry in a kernel-owned virtual process table, not an OS process. Guest JavaScript runs in V8 isolates; guest commands like `sh` and coreutils run as WebAssembly. Neither is `node` or a host binary.\n- **Every process operation is a syscall into the kernel.** Spawning, waiting, signaling, reading stdout, and resizing a PTY all cross from the untrusted executor into the sidecar-owned kernel, which services them against virtualized resources.\n\n## The virtual process table\n\nEach VM owns one process table. It is the authority for what is \"running\"\ninside that VM; nothing in it corresponds to a host PID.\n\n- **Per-VM and isolated.** Two VMs have two independent tables. A PID in one VM is meaningless in another, and processes are never visible across the VM boundary.\n- **Holds every guest process,** not only the ones a client started explicitly. A `spawn` from the client, a child spawned by guest `node:child_process`, and the processes behind a shell pipeline are all table entries. This is why the system-wide `allProcesses` snapshot can show more than what the client launched.\n- **Tracks lifecycle and lineage.** Each entry carries its PID, the command and arguments, parent PID (so the tree can be reconstructed), running/exited status, exit code once collected, and its attached stdio endpoints.\n- **Records a driver.** An entry knows which execution backend services it (for example a V8 isolate versus a WASM runtime). This is the `driver` field surfaced on `allProcesses`. Drivers differ in *how* the code runs; they share the same table, the same kernel-owned stdio, and the same boundary.\n\n\u003CNote>The process table is part of the kernel the sidecar owns. The executor never mutates it directly; it can only ask the kernel to create, wait on, or signal an entry. That request-only relationship is the sidecar-to-executor boundary applied to processes.\u003C/Note>\n\n## How a spawn is serviced\n\nA spawn, whether it originates from a client `spawn`/`exec` call or from guest\n`node:child_process`, follows one path through the kernel:\n\n1. **The request crosses into the kernel.** A client call arrives over the wire protocol; a guest call arrives as a syscall from the executor. Either way the kernel, not the caller, performs the work.\n2. **Permission check.** The kernel applies the VM's permission policy before doing anything. The sidecar installs `allow` when `childProcess` is omitted; an explicit deny rejects the spawn with `EACCES`. The policy is trusted input, the guest making the request is not.\n3. **Resolve the program.** The command is resolved against the VM's virtual filesystem (PATH lookup over the VFS), not the host. The resolved program decides the driver: a JavaScript entrypoint runs in a V8 isolate; a `.wasm` program (including `sh` and coreutils) runs on the WASM runtime.\n4. **Allocate the table entry.** The kernel assigns a virtual PID, records the command, arguments, environment, working directory, and parent PID, and links stdio endpoints (see below).\n5. **Start execution.** The driver begins running the program. For a one-shot `exec` the kernel additionally collects stdout, stderr, and the exit code and returns them as the call's result; for `spawn` it leaves the process running and streams output via events.\n6. **Reap and record exit.** When the program finishes, the kernel records the exit code on the table entry and marks it exited, which is what a `wait`/`waitProcess` resolves against and what `processExit` reports.\n\nSignals (`stopProcess` / SIGTERM, `killProcess` / SIGKILL) are the same shape: a\nrequest into the kernel, which applies it to the virtualized process rather than\nto any host process.\n\n## Stdio bridging\n\nStandard streams are kernel-owned objects, not host file descriptors. Each\nprocess entry has stdin, stdout, and stderr endpoints that the kernel wires up\nwhen the entry is created.\n\n- **Capture vs. stream.** For `exec`, the kernel buffers stdout and stderr and hands them back when the process exits. For `spawn`, output is delivered incrementally as `processOutput` events tagged with the PID and the stream (`stdout`/`stderr`), and `processExit` signals completion.\n- **Writable stdin.** `writeProcessStdin` pushes bytes into the process's stdin endpoint; `closeProcessStdin` closes the write side so programs that read to EOF (like `cat`) can finish. None of this touches a real pipe on the host.\n- **Pipes between processes.** Shell pipelines (`a | b`) connect one process's stdout endpoint to the next process's stdin endpoint through kernel-owned pipes. The pipe is a virtual object in the kernel, so a pipeline behaves like Linux without any host IPC.\n\nBecause these endpoints are kernel objects, the same bridging works identically\nwhether the process is a V8 isolate or a WASM program; the driver writes to and\nreads from kernel stdio, not from anything host-provided.\n\n## PTYs and interactive shells\n\nAn interactive shell needs a terminal, not just piped stdio: line editing, job\ncontrol signals, and window size all depend on a PTY. The kernel provides\nvirtual PTY devices for this.\n\n- **A shell is a process plus a PTY.** `openShell` allocates a kernel PTY and starts a shell process attached to it, returning a `shellId`. The PTY is a virtualized terminal device, never a host `/dev/pts` entry.\n- **Bidirectional terminal I/O.** `writeShell` feeds keystrokes into the PTY master side; everything the shell and its children emit comes back as `shellData` events. This carries terminal control sequences, so full-screen TUIs behave correctly.\n- **Resize is a terminal operation.** `resizeShell` updates the PTY's window size (columns and rows), which the kernel propagates to the foreground process the way a real terminal resize would, so programs relying on `TIOCGWINSZ`-style sizing redraw correctly.\n- **Teardown.** `closeShell` tears down the PTY and the attached shell process. An open shell keeps the VM active, the same way an open PTY keeps a session alive on a real system.\n\n## WASM sh and coreutils on the process model\n\nThe shell and the standard commands behind process execution are not special\nhost helpers; they are ordinary guest processes that happen to be WebAssembly.\nFor the full WASM execution model see [WASM VM](/docs/architecture/posix-syscalls); here is how it\nmaps onto the process table specifically.\n\n- **They are normal table entries.** Running `sh`, `ls`, `cat`, etc. allocates virtual PIDs and table entries exactly like any other process, with the WASM driver recorded on each. A pipeline of coreutils is several entries linked by kernel pipes.\n- **POSIX process semantics are virtualized, not borrowed from the host.** Plain WASI has no process model (no `fork`/`exec`/`wait`). agentOS supplies those semantics through kernel-backed host imports, so a WASM program that spawns and waits on a child drives the *same* kernel process table that JS guests use. A coreutil spawning a subcommand is one table entry creating another.\n- **Same stdio, same PTY.** WASM processes read and write the kernel stdio endpoints described above, and a shell built from WASM `sh` attaches to a kernel PTY just like any interactive shell. The driver differs; the kernel-owned plumbing does not.\n\nThis is why the process model is uniform: whether an entry is a V8 isolate or a\nWASM binary, it lives in the same per-VM table, goes through the same\npermission-checked spawn path, and uses the same kernel-owned stdio and PTYs.\n\n## See also\n\n- [Processes & Shell](/docs/processes): the client API for running and managing processes.\n- [WASM VM](/docs/architecture/posix-syscalls): how WebAssembly guests get POSIX process, user, and network semantics.\n- [Architecture](/docs/architecture): components, the trust boundary, and the request lifecycle.\n- [Permissions](/docs/permissions): the policy the kernel checks on every spawn.","src/content/docs/docs/architecture/processes.mdx","2c55ee590c157bfc","docs/architecture/sessions-persistence",{"id":410,"data":412,"body":415,"filePath":416,"digest":417,"deferredRender":16},{"title":413,"description":414},"Sessions & Persistence","How agentOS, ACP, RivetKit actors, and durable session persistence fit together.","agentOS runs coding agents inside VMs and talks to them through the Agent\nCommunication Protocol (ACP). RivetKit wraps those VMs in durable actors, so a\nsession can survive actor sleep/wake even though the live VM and agent process\ndo not.\n\n## Layers\n\nagentOS session architecture has four layers:\n\n| Layer | Responsibility |\n| --- | --- |\n| RivetKit actor | Owns the public API and durable actor-local SQLite state. |\n| agentOS client | Thin facade used by the actor to create sessions, prompt agents, and call the sidecar. |\n| agentOS sidecar ACP extension | Launches ACP adapters inside the VM, speaks JSON-RPC, handles permissions, and owns resume orchestration. |\n| ACP adapter / agent | Runs inside the VM and speaks ACP over stdio. |\n\nThe actor is durable. The VM is disposable. The ACP agent process is live state\ninside the VM.\n\n## API Shape\n\nThe actor-facing session API is:\n\n- `createSession(agentType, options)`\n- `sendPrompt(sessionId, text)`\n- `closeSession(sessionId)`\n- `listPersistedSessions()`\n- `getSessionEvents(sessionId)`\n\n`sessionId` is the stable, client-facing id. If fallback resume creates a new\nlive ACP session id after wake, the actor keeps an internal\n`externalSessionId -> liveSessionId` remap. Clients keep using the original\n`sessionId`.\n\n## Create Flow\n\n1. The actor calls agentOS `createSession`.\n2. The sidecar starts the ACP adapter process inside the VM.\n3. The sidecar sends ACP `initialize`.\n4. The sidecar sends ACP `session/new`.\n5. The actor persists session metadata in `agent_os_sessions`.\n6. The actor starts capturing ACP `session/update` events for the session.\n\nPersisted session metadata includes:\n\n- `session_id`\n- `agent_type`\n- agent capabilities and agent info\n- create-time `cwd`\n- create-time `env`\n\nThe create-time `cwd` and `env` are used later so resumed sessions start with\nthe same working directory and environment they were created with.\n\n## Prompt Flow\n\n1. The actor receives `sendPrompt(sessionId, text)`.\n2. If the session is persisted but not live in the current VM, the actor lazily\n resumes it first.\n3. The actor writes a synthetic `user_prompt` event before forwarding the\n prompt.\n4. The actor forwards the prompt to the live ACP session id.\n5. The sidecar sends ACP `session/prompt`.\n6. Inbound ACP `session/update` events are captured into\n `agent_os_session_events`.\n\n`agent_os_session_events` is ordered per session. Sequence numbers are allocated\ninside the SQLite insert so concurrent prompt and stream captures cannot reuse\nthe same sequence number.\n\n## Sleep And Wake\n\nWhen a RivetKit actor sleeps:\n\n- the VM is destroyed\n- ACP adapter processes exit\n- the actor's in-memory `live_sessions` remap is lost\n- actor SQLite survives\n\nWhen the actor wakes:\n\n- a fresh VM boots\n- stable session ids still exist in `agent_os_sessions`\n- no ACP session is live yet\n- resume happens lazily on the next prompt\n\n## Resume Flow\n\nOn the first post-wake prompt for a persisted session:\n\n1. The actor reads `agent_os_sessions`.\n2. The actor reconstructs a Markdown transcript from\n `agent_os_session_events`.\n3. The actor writes the transcript to\n `/root/.agentos/threads/\u003CsessionId>.md`.\n4. The actor calls sidecar `resumeSession` with:\n - stable external `sessionId`\n - agent type\n - transcript path\n - persisted create-time `cwd`\n - persisted create-time `env`\n\nThe sidecar then chooses one of two resume paths.\n\n### Native Resume\n\nIf the ACP agent advertises `loadSession` or `resume`, the sidecar sends\n`session/load` or `session/resume`.\n\nWhen native resume succeeds:\n\n- the live ACP id is the stable external `sessionId`\n- the agent restores its own context\n- no transcript preamble is injected\n\nOpenCode uses this path when its own session store is still available in the\ndurable VM filesystem.\n\n### Transcript Fallback\n\nIf native resume is unsupported, or if native resume reports a normalized\n`unknown_session`, the sidecar falls back to a fresh session:\n\n1. The sidecar sends ACP `session/new`.\n2. The sidecar returns the new live ACP id to the actor.\n3. The actor stores `externalSessionId -> liveSessionId`.\n4. The sidecar prepends a one-shot preamble to the next prompt pointing at the\n transcript path.\n\nThe fallback is universal because it only requires the agent to read a file with\nits normal tools. It is lower fidelity than native resume because the transcript\nis pointed to, not automatically loaded into the agent's context window.\n\n## Unknown Session Normalization\n\nAdapters report missing sessions differently. The sidecar normalizes known\nmissing-session shapes into:\n\n```json\n{ \"error\": { \"data\": { \"kind\": \"unknown_session\" } } }\n```\n\nFor example, OpenCode currently reports a missing native session as:\n\n```json\n{ \"code\": -32603, \"data\": { \"details\": \"NotFoundError\" } }\n```\n\nThat shape is captured before normalization in tests, then normalized so the\nresume state machine can safely choose transcript fallback. Other internal\nerrors still propagate as failures.\n\n## Persistence\n\nDurable session state lives in actor SQLite:\n\n| Table | Purpose |\n| --- | --- |\n| `agent_os_sessions` | Stable session registry, agent type, capabilities, agent info, create-time `cwd`, and create-time `env`. |\n| `agent_os_session_events` | Append-only prompt and ACP event log keyed by the stable external `sessionId`. |\n\nThe transcript file is not canonical state. It is a disposable render of\n`agent_os_session_events`, rebuilt on demand during fallback resume.\n\n## What Is Durable\n\n| Data | Survives sleep/wake? | Notes |\n| --- | --- | --- |\n| Actor SQLite | Yes | Stores session registry, events, preview tokens, and other actor data. |\n| VM filesystem | Yes, when backed by the actor sqlite_vfs root | Used by agents and resume transcripts. |\n| Live ACP process | No | Recreated on wake. |\n| Actor in-memory vars | No | Includes the live ACP id remap. |\n| Client-facing `sessionId` | Yes | Stored in `agent_os_sessions`. |\n\n## Where To Look In Code\n\n- Sidecar ACP orchestration:\n `crates/agentos-sidecar/src/acp_extension.rs`\n- agentOS TypeScript client surface:\n `packages/core/src/agent-os.ts`\n- RivetKit actor session actions:\n `rivetkit-rust/packages/rivetkit-agent-os/src/actions/session.rs`\n- RivetKit persistence helpers:\n `rivetkit-rust/packages/rivetkit-agent-os/src/persistence.rs`","src/content/docs/docs/architecture/sessions-persistence.mdx","7a4569a76c301276","docs/custom-software/building-wasm",{"id":418,"data":420,"body":423,"filePath":424,"digest":425,"deferredRender":16},{"title":421,"description":422},"Building Binaries","Compile WASM command binaries for agentOS from source in the secure-exec registry.","WASM command packages ship **compiled `.wasm` binaries** in their `bin/` that run inside the VM as guest commands.

It exports a `{ packagePath }` descriptor pointing at the packed `dist/package.aospkg`, and declares which binaries it ships in its `agentos-package.json` (`commands`, plus optional `aliases` and `stubs`).\n\n## Build\n\nEverything runs through `just` recipes at the secure-exec repo root:\n\n```bash\njust registry-native # compile ALL native wasm binaries (slow; once per checkout)\njust registry-native-cmd sh # recompile ONE command (cargo package cmd-sh)\njust registry-build # stage + assemble every registry package\njust registry-build ripgrep # ... or just one\njust registry-status # per-package state; --remote adds npm dist-tags\n```\n\nThe native build compiles each command for `wasm32-wasip1` with the pinned **nightly** toolchain from `rust-toolchain.toml` (the build vendors and patches `std` for WASI), optimizes with `wasm-opt`, and drops the binaries in `registry/native/target/wasm32-wasip1/release/commands/`. C-based commands (e.g. `sqlite3`, `unzip`, `wget`, `zip`) compile with a **wasi-sdk** clang toolchain via `make -C registry/native/c`.\n\nEach package's build then runs the **agentos-toolchain** lifecycle: `agentos-toolchain stage` copies the binaries listed in the package's `agentos-package.json` into its `bin/`, and `agentos-toolchain build` assembles the clean `dist/package/` dir with a `bin` map in its `package.json` and packs it into `dist/package.aospkg` (the `{ packagePath }` target).\n\n## Add a new command package\n\n1. Add the command source as `registry/native/crates/commands/\u003Cname>/` (cargo package `cmd-\u003Cname>`; Rust) or under `registry/native/c/` (C).\n2. Create `registry/software/\u003Cname>/` as an `@agentos-software/\u003Cname>` npm package that exports a `{ packagePath }` descriptor pointing at `dist/package.aospkg`.\n3. Declare the shipped binaries in its `agentos-package.json`: `{ \"commands\": [\"\u003Cname>\"] }` (plus `aliases`/`stubs` if needed).\n4. If it belongs in a meta-package (e.g. `common` or `build-essential`), add it there.\n5. Verify with `just registry-native-cmd \u003Cname> && just registry-build \u003Cname>` and `just registry-test`.\n\n## Let an agent build it\n\nThis is a mechanical, well-scoped task, so you can hand it to a coding agent. A prompt like:\n\n```text\nAdd a WASM command package for `\u003Ccommand>` to the secure-exec registry:\n- put the Rust source at registry/native/crates/commands/\u003Ccommand>/ as a cargo\n package named cmd-\u003Ccommand>,\n- create registry/software/\u003Ccommand>/ as an @agentos-software/\u003Ccommand> npm\n package that exports a { packagePath } descriptor and declares the command in\n its agentos-package.json,\nthen run `just registry-native-cmd \u003Ccommand> && just registry-build \u003Ccommand>`\nand `just registry-test`, and fix any failures.\n```\n\n## Using the registry\n\nInstall a published package and pass it to `software`.

The package's name, optional agent block, and any files/env it provides are authored in an `agentos-package.json` next to your sources; the toolchain compiles that JSON into the `.aospkg`'s embedded manifest at pack time (the JSON itself is never shipped into the VM). Pick the quickstart that matches what you're packaging.\n\n## Quickstart\n\n### WebAssembly\n\n\u003CSteps>\n\n1. **You have** C or Rust source for a command. (Most common commands already ship as `@agentos-software/*` packages you can use directly — compile only new or custom ones.)\n\n2. **Compile it** to WebAssembly — see [Building Binaries](/docs/custom-software/building-wasm). There's **no `pack` step**: WASM binaries are self-contained, so the compile output is already the package — a `bin/` of `\\0asm` files plus a `package.json` for the name/version:\n\n ```\n my-cmds/\n ├── package.json\n └── bin/\n ├── tool-a # \\0asm WebAssembly\n └── tool-b\n ```\n\n3. **Define it** — point `defineSoftware()` at that directory:\n\n \u003CCodeSnippet file=\"examples/software/quickstart-wasm/my-cmds.ts\" />\n\n4. **Use it** — pass it to a VM; the commands are on `$PATH`:\n\n \u003CCodeSnippet file=\"examples/software/quickstart-wasm/index.ts\" />\n\n\u003C/Steps>\n\n### Node.js\n\n\u003CSteps>\n\n1. **You have** a local project whose `package.json` `bin` names its commands:\n\n ```\n my-tool/\n ├── package.json # \"bin\": { \"my-tool\": \"cli.js\" }\n └── cli.js # #!/usr/bin/env node\n ```\n\n2. **Package it** — `pack` installs the full dependency closure into a self-contained package directory (a flat `node_modules` plus a `bin` map of real files):\n\n ```bash\n npx @rivet-dev/agentos-toolchain pack ./my-tool\n # writes ./my-tool-package/ (override the location with --out \u003Cdir>)\n # my-tool-package/\n # ├── package.json # \"bin\": { \"my-tool\": \"node_modules/my-tool/cli.js\" }\n # └── node_modules/ # flat, self-contained closure\n ```\n\n Commands come from the package's `package.json` `bin` map — **real files, no symlinks** — so the result ships cleanly as an npm dependency. (The runtime makes the `/opt/agentos/bin` symlinks itself when it mounts the package.) A native `.node` addon is an error (it can't run in V8); re-run with `--prune-native` to drop unreachable ones.\n\n3. **Define it** — point `defineSoftware()` at the packaged directory:\n\n \u003CCodeSnippet file=\"examples/software/quickstart-node/my-tool.ts\" />\n\n4. **Use it** — pass it to a VM; `my-tool` is now on `$PATH`:\n\n \u003CCodeSnippet file=\"examples/software/quickstart-node/index.ts\" />\n\n\u003C/Steps>\n\n### Agent\n\nAn agent is a Node.js or WASM package (packaged exactly as above) whose `agentos-package.json` carries an **`agent` block** naming a `bin/` command that speaks ACP over stdio.\n\n\u003CSteps>\n\n1. **You have** an npm package with a `bin/` command that speaks ACP over stdio.\n\n2. **Package it** — same `pack` as Node.js, with `--agent` naming the ACP entrypoint. That writes the `agent` block into the package's `agentos-package.json`:\n\n ```bash\n npx @rivet-dev/agentos-toolchain pack @scope/my-agent --out ./packages --agent my-agent-acp\n # → ./packages/my-agent/current (its agentos-package.json now has the agent block)\n ```\n\n3. **Define it** — point `defineSoftware()` at the packaged directory; the agent block is already in its `agentos-package.json`:\n\n \u003CCodeSnippet file=\"examples/software/quickstart-agent/my-agent.ts\" />\n\n4. **Use it** — `createSession()` launches the agent by spawning its `acpEntrypoint`:\n\n \u003CCodeSnippet file=\"examples/software/quickstart-agent/index.ts\" />\n\n\u003C/Steps>\n\n## Reference\n\n### The descriptor\n\nA software entry is just a pointer to the packed package:\n\n```ts\ndefineSoftware({\n packagePath: string, // absolute host path to the packed .aospkg\n // (or a package directory, for local development)\n})\n```\n\nThe normal `packagePath` is the `dist/package.aospkg` that `agentos-toolchain build`/`pack` emit —\na single file holding the package manifest, a precomputed mount index, and the package's mount tar.\nA directory is accepted for local development; it must contain **only the package** — a\n`package.json` with a `bin` map, the runtime files (`bin/`, a flat `node_modules`), and an\n`agentos-package.json`. It is mounted read-only, so **don't point it at a source root**: that drags\n`src/`, dev `node_modules/`, `tsconfig`, and build caches into the VM.\n\n\u003CNote>\n`pack` already emits the packed `.aospkg`. For a package you build by hand (e.g. compiled WASM),\nrun `agentos-toolchain build` to assemble `dist/package/` and pack `dist/package.aospkg`, then\npoint `packagePath` there — never at the workspace root:\n\n```ts\nconst packagePath = resolve(import.meta.dirname, \"dist/package.aospkg\");\nexport default defineSoftware({ packagePath });\n```\n\u003C/Note>\n\n### `agentos-package.json`\n\nThe package's name, optional agent block, and any files/env it provides are authored in an\n`agentos-package.json` at the package root. It is **toolchain input**: at pack time it is compiled\ninto the `.aospkg`'s embedded manifest (which is what the sidecar reads) and stripped from the\npacked files, so the JSON never ships into the VM and the metadata never travels on the wire. For\ncommand/WASM packages it is **generated** for you (name from `package.json`); for agents you\nauthor the `agent` block (or `agentos-toolchain pack --agent \u003Ccmd>` writes it).\n\n```jsonc\n{\n \"name\": \"my-agent\", // → /opt/agentos/\u003Cname>\n \"agent\": { // optional — also exposes an agent session\n \"acpEntrypoint\": \"my-agent-acp\", // bin/ command that speaks ACP over stdio\n \"env\": { }, // static env for the adapter\n \"launchArgs\": [],\n \"snapshot\": false // SDK snapshot optimization\n },\n \"provides\": { // optional — files + env the package contributes\n \"env\": { \"EXAMPLE_HOME\": \"/opt/agentos/my-agent\" },\n \"files\": [{ \"source\": \"etc/example.conf\", \"target\": \"/etc/example.conf\" }]\n }\n}\n```\n\n- **`name`** — the package name; commands and the package mount under `/opt/agentos/\u003Cname>`.\n- **`agent.acpEntrypoint`** — the `bin/` command spawned to start a session; speaks ACP over stdio.\n- **`agent.env`** — static env vars for the adapter, merged under the user env. Every command is on `$PATH`, so point at one directly, e.g. `{ \"PI_ACP_PI_COMMAND\": \"/opt/agentos/bin/pi\" }` so `pi-acp` can spawn the `pi` CLI.\n- **`agent.launchArgs`** — extra CLI args prepended when launching the adapter.\n- **`agent.snapshot`** (default `false`) — load the SDK [once per sidecar](#sdk-snapshotting--snapshot-safety) via a shared V8 heap snapshot instead of per session. Falls back to per-session loading if the SDK isn't snapshot-safe, so it only affects startup latency.\n- **`provides.env`** — env vars merged into the VM's base environment (existing values win — a package never clobbers the user env).\n- **`provides.files`** — read-only files overlaid into the VM filesystem. Each `{ source, target }` maps a path **inside the package** to an **absolute VM path**; the sidecar mounts them as zero-copy read-only lower layers (a guest write copies-up, never touching the host). A missing `source` is a fatal packaging error.\n\n## Advanced\n\n### Meta-packages\n\nA software entry may be an **array** of descriptors, so one package can bundle several. Pass arrays directly to `software`:\n\n```ts\nconst vm = agentOS({\n software: [pi, buildEssential /* = [coreutils, make, git, curl] */],\n});\n```\n\n### SDK snapshotting & snapshot-safety\n\nA V8 heap snapshot freezes the heap *after* the SDK's modules are evaluated, then seeds each new session's isolate from it. This works only if the SDK's **module-init** code (everything that runs at `import`/`require` time) doesn't:\n\n- Create **native handles** — load a `.node` addon, instantiate WebAssembly, or produce a V8 `External`/`Foreign` at top level.\n- Open a **file descriptor, socket, timer, or worker**, or leave a **pending promise**.\n- Bake in **non-deterministic or per-session state** — `process.env`, cwd, `Date.now()`, `Math.random()`, a UUID.\n\nDefer all of the above behind functions or lazy `import()` that run per session.

The toolchain provides four subcommands:\n\n| Command | What it does |\n|---|---|\n| `stage --commands-dir \u003Cdir>` | Populate `bin/` from a directory of compiled binaries, per the `commands` / `aliases` / `stubs` lists in the package's `agentos-package.json`. |\n| `build` | Assemble `dist/package/` from `bin/` (+ optional `share/`) and pack it into `dist/package.aospkg` — the runtime artifact with the embedded manifest (the `agentos-package.json` is pack-time input, not shipped). |\n| `pack` | Build a self-contained node-closure package from an npm package or local dir (JS agents; validates headers, rejects native addons). |\n| `publish` | Publish the built package to npm. Dist-tag is **`dev` by default**; the `latest` pointer only moves with an explicit `--latest`. |\n\n## Building\n\nIn the AgentOS registry, the `just` recipes drive the toolchain (see [Building Binaries](/docs/custom-software/building-wasm)):\n\n```bash\njust registry-native # compile the native wasm binaries (once per checkout)\njust registry-build # stage + assemble every registry package\njust registry-build coreutils # ... or one package\njust registry-status # inspect: version, staged bin/, assembled dist\n```\n\n## Publishing\n\nRegistry packages **version independently** — each package carries its own semver in its `package.json`. Bump and commit the version, then:\n\n```bash\njust registry-publish coreutils # publish under dist-tag `dev`\njust registry-publish coreutils my-branch # ... under a custom tag\njust registry-publish coreutils latest # DELIBERATE release: moves `latest`\njust registry-publish-all # every built software package, tag `dev`\n```\n\nConsumers installing `@agentos-software/\u003Cname>` with no tag resolve `latest`, so `latest` is reserved for deliberate releases — a dev publish can never clobber what users install.\n\n## Consuming published packages\n\nIn agent-os, the `@agentos-software/*` packages are pinned **per-package** in the workspace catalog. Manage the pins with the `just` recipes (never hand-edit them):\n\n```bash\njust agentos-pkgs-status # current mode + pinned versions\njust agentos-pkgs-set-version coreutils 0.3.1 # pin one package\njust agentos-pkgs-update # re-pin all from the `latest` dist-tag\njust agentos-pkgs-update dev # ... or from another tag\n```\n\n## Local development\n\nAgentOS consumes local registry builds by default because the registry packages\nare pnpm workspace members. Build the native commands with `just registry-native`\nand assemble packages with `just registry-build`; no sibling checkout or\npublished package is required while iterating.\n\nPublished-version pins exist only in release validation and downstream\nconsumers. The AgentOS workspace itself stays self-contained.\n\n## Publishing from your own repo\n\nThe toolchain is not registry-specific — any repo can produce and publish agentOS packages with `npx @rivet-dev/agentos-toolchain`:\n\n```bash\n# a package dir with package.json + agentos-package.json + your compiled binaries\nnpx @rivet-dev/agentos-toolchain stage --commands-dir ./build/wasm\nnpx @rivet-dev/agentos-toolchain build\nnpx @rivet-dev/agentos-toolchain publish --tag dev # or --latest for a release\n```\n\nFor a JS agent, `pack` replaces `stage`/`build`:\n\n```bash\nnpx @rivet-dev/agentos-toolchain pack . --out dist/package --agent my-acp-entrypoint\n```\n\nThe published package is a plain npm dependency — consumers import its descriptor and pass it to `software` exactly like the registry packages. See [Software Definition](/docs/custom-software/definition) for the descriptor shape.","src/content/docs/docs/custom-software/publishing.mdx","8ef166f820dd755b","cookbooks/agent-to-agent",{"id":442,"data":444,"body":447,"digest":448,"rendered":449},{"title":445,"description":446},"Agent to Agent","Bridge two isolated agent VMs: a writer agent calls a reviewer agent through a binding.","\nRun two agents in separate isolated VMs and let one delegate to the other.
