If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews. How do review limits work?CodeRabbit enforces per-developer PR review limits within each organization. For paid Pro and Pro+ reviews, CodeRabbit uses a developer's included PR review attempts over the past 7 days to set the current hourly allowance. At typical activity levels, the full plan allowance applies. Higher sustained activity can lower the allowance until earlier attempts leave the 7-day window. Please refer docs for additional details.

📝 WalkthroughWalkthroughChangesLegacy profile isolation and re-pairing
Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🟠 High · up to The PR changes legacy-profile handling to isolate local data and require all-device re-pairing. At the current head, recovery metadata is stored without protection, completion is not crash-safe, and the durable re-pairing requirement can still be cleared or missed by setup-state and unlock flows. This can expose migration metadata, leave cleanup inconsistent, or strand upgraded users without the required re-pairing prompt, so the PR is not safe to merge until these paths are corrected.

type and populate it from SetupStateSummary in
MobileEngine::query_space_state(), preserving the existing mappings for
has_completed, space_id, current_invitation, and device_name.
In `@crates/uc-application/src/facade/space_setup/facade.rs`:
- Around line 102-152: Update the setup flow around adopt_isolated_space,
clear_all_relationships, and clear_space_security_state_except so device-name
and local-identity prerequisites are validated before any destructive mutation.
Make the migration restart-safe by persisting a durable in-progress phase before
cleanup and resuming or completing it after failures, or use an equivalent
transactional/resumable sequence; add retry tests covering failures at each
destructive boundary.
- Around line 503-507: The session-activation flow currently runs
LegacyProfileIsolationUseCase only from unlock_space, so try_resume_session
skips isolation after silent activation. Factor or reuse a single
post-activation isolation path and invoke it after successful activation from
both try_resume_session and unlock_space, preserving error propagation; add
coverage for resume with legacy_profile_isolation_required enabled.
In `@crates/uc-core/src/membership/revocation.rs`:
- Around line 9-28: Implement custom Deserialize for ProtectionGroupId so
deserialization parses the input string through ProtectionGroupId::from_string
and propagates InvalidProtectionGroupId for empty, non-ASCII, or oversized
values. Remove the derived Deserialize implementation while preserving the
existing Serialize behavior and public constructors.
In `@crates/uc-engine/src/runtime/dispatch.rs`:
- Around line 475-484: The successful UnlockSpace handling in the dispatch flow
must not silently discard failures from current_facade or query_setup_state.
Update the RePairingRequired notification path around current_facade,
query_setup_state, and re_pairing_scope_for_setup_state to either schedule a
retry or guarantee a later setup-state query trigger, while preserving the
persisted flag as the fallback and recording an appropriate diagnostic.
In `@docs/specs/026-legacy-profile-isolation-and-re-pairing.md`:
- Line 17: Update the isolation flow around adopt_isolated_space and set_status
so the target SpaceId is persisted as an isolation-in-progress record before any
cleanup mutation, then reuse that same ID on retries. Ensure interrupted
adoption or cleanup recovers the prior target atomically instead of generating a
new SpaceId, and only finalize the re_pairing_required status after cleanup
completes.
In `@docs/specs/uc-engine-interface.md`:
- Around line 46-48: Update the public QuerySetupState operation contract to
document re_pairing_required, including that true signals the missed
RePairingRequired recovery state, false indicates no re-pairing is required, and
the flag clears after the product acknowledges or completes the required
re-pairing flow.
In `@scripts/architecture/check-engine-repository.mjs`:
- Around line 494-497: Update the event validation in the check-engine
repository script to verify the complete RePairingRequired event structure

kind() mapping to re_pairing_required, while preserving the existing addProblem
behavior when any required context is missing.
In `@tests/hosts/uc-mobile-probe-core/src/lib.rs`:

Expose the persisted flag through the UniFFI setup-state result.
MobileEngine::query_space_state() returns SpaceState, but SpaceState still exposes only has_completed, space_id, current_invitation, and device_name. Add re_pairing_required to that binding type and map it from SetupStateSummary.
Without this field, iOS and Android cannot recover the re-pairing state when the unlock event is missed or the engine starts with the flag already persisted.

Make the completion transition crash-safe.
The specification writes re_pairing_required = true and then removes the isolation-in-progress record. If the process exits between these writes, the next unlock can observe both completed and in-progress state. The specification does not define which state wins or prevent cleanup from running again. Commit both changes atomically, or treat re_pairing_required = true as terminal and remove stale progress without repeating cleanup.
As per coding guidelines, Specs must document stable technical behavior and design, including edge cases, failure behavior, and compatibility requirements.
