When opening a remote SSH block that carries a term:tmux:session meta key, the shell startup automatically runs `tmux new -A -t <session>`, attaching to the named tmux session (creating it if absent, resuming if present) without any manual typing. Changes: - add MetaKey_TermTmuxSession (term:tmux:session) meta key constant - makeSwapToken detects the key and injects the auto-attach script only for remote connections - session name is wrapped in shell single quotes to prevent injection - sync TypeScript type binding and add unit tests for the acceptance criteria
Add a Tmux Sessions submenu to the context/settings menu of remote SSH blocks: call the listtmuxsessions RPC to fetch session names from the remote host, show a checkbox single-select marking the currently associated session, and persist/clear term:tmux:session with an immediate controller restart. Changes: - add listtmuxsessions RPC (runs `tmux list-sessions` remotely) - make getContextMenuItems/getSettingsMenuItems async for dynamic submenu - extract tmux-session pure logic with unit tests on both ends

Remote tmux sessions are listed through an SSH login shell and exposed in asynchronous terminal menus. Selecting a session persists the metadata and restarts the controller. Remote controllers attach to the selected session only for bash and zsh. Tests cover session transitions, parsing, attachment guards, and shell-safe session names. Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🔵 Low · up to The change is mergeable with owner awareness: if the remote session query returns no value, the Tmux Sessions menu may fail to populate instead of showing an empty list.

Normalize null RPC results to an empty list.
When sendRpcCommand returns null, WshClient.wshRpcCall returns null instead of a promise. The tmux consumer then calls sessions.includes(...) outside its rejection path and can throw. Return [] from this wrapper for null results, or guard the consumer.

Address functional issues surfaced during review: - Surface the Tmux Sessions submenu in the terminal context menu, not just the header settings menu (drop the includeTmuxSessions flag). - Restrict auto-attach script injection to POSIX shells (bash/zsh); skip fish/pwsh, whose syntax cannot parse the fragment. - Prefix tmux list-sessions output with a sentinel and parse only sentinel-prefixed lines, so login-shell profile text on stdout can never leak into the session list. - Normalize a null listtmuxsessions result to an empty array so the consumer never throws on a downed connection. Adds regression tests for unsupported shells, sentinel parsing, and profile-output filtering.

Strip only the sentinel and trailing CRLF when parsing tmux session names, keeping a name's own surrounding whitespace intact (tmux permits it). Adds regression tests for CRLF endings and padded session names.

Summary
This PR makes Wave Terminal's remote SSH blocks feel like a proper tmux client by adding two tightly-coupled capabilities:
term:tmux:sessionmeta key automatically runstmux new -A -t <session>when its shell starts, so reopening a connection reattaches to the same tmux session (creating it if absent, resuming if present) with zero manual typing.Tmux Sessionssubmenu that lists live sessions on the remote host via a newlisttmuxsessionsRPC, shows the currently-associated session as a checked item, and lets you switch or clear the association in one click.Motivation
Remote development over SSH is the bread-and-butter of Wave Terminal, but tmux session continuity is currently manual: every reconnect means hand-typing
tmux new -A -t <name>(or first runningtmux lsto remember the name). This makes long-lived remote workspaces — model servers, build hosts, pairing sessions — noticeably worse to use than a dedicated terminal/tmux client.The
term:tmux:sessionmeta key fits Wave Terminal's existing block-meta model (alongsideterm:bellindicator,term:osc52, etc.), and the submenu surfaces the same workflow through a discoverable UI, so users don't need to know tmux internals to keep sessions alive.Why
new -A(notattach)tmux new -A -t <name>is deliberately chosen: it attaches to an existing session or creates it if missing, which is exactly the "reconnect idempotently" semantics a terminal wants — no separate create/attach branching, no error when the session doesn't yet exist.Changes

listtmuxsessionsRPC (pkg/wshrpc/wshserver/wshserver.go) runstmux list-sessions -F '#{session_name}'through a login shell on the remote and returns parsed names (parseTmuxSessionList). Local/disconnected/no-tmux cases return an empty list.getContextMenuItems/getSettingsMenuItemsbecome async (frontend/app/block/blockframe-header.tsx,frontend/app/view/term/term-model.ts,term.tsx) so the submenu can fetch a fresh session snapshot when the menu opens and mark the active session as checked.term:tmux:sessionand immediately restarts the block controller to apply it (without stopping the remote tmux server).frontend/app/view/term/tmux-session.ts(toggleTmuxSession,applyTmuxSessionChange) for testability.Test plan
