How can I continue?After more reviews become available, a review can be triggered using the To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. 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 for each organization. Most developers receive the normal plan review availability. For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🔵 Low · up to The new retry behavior can retain terminal-state attribution from the run it joined, so a cancellation during the retry could associate the failure with the previous turn or compaction marker. This is a bounded correctness risk; the PR is mergeable with explicit owner awareness or a follow-up to reset that state. Sequence Diagram(s)sequenceDiagram

gate.resolve so it explicitly asserts that messages contains the submitted
message identified by messageID before releasing the gate. Keep polling with the
existing timeout and sleep behavior, but fail the test on timeout instead of
resolving gate and allowing the run to continue without confirming persistence.

1827-1910: 🚀 Performance & Scalability | 🔵 Trivial | 💤 Low valueConsider narrowing the terminal write lock to a single session.
terminalWriteLockis created once per layer, so every terminal-carrier write across all sessions is serialized. Each critical section reads the full message list of a session. Concurrent sessions that fail at the same time queue behind each other. A per-session lock keeps the same idempotence guarantee without cross-session coupling.This only affects error and cancellation paths, so it is optional.

Prepare the PawWork 2026.8.2 stable release from the current dev baseline after #1546 and #1558. Change boundary: - bump the desktop package version from 2026.8.1 to 2026.8.2 - update only the matching Bun lockfile workspace entry Verification: - version contract failed on 2026.8.1 and passed on 2026.8.2 - release metadata and workflow contracts: 21 passed, 0 failed - release TypeScript check passed - frozen install passed in the dedicated release worktree without additional lockfile changes - all required PR checks passed, including macOS smoke, E2E, CodeQL, dependency review, and the full Windows matrix - the dev Windows runner/header-download transient was rerun successfully in run 32001323938 attempt 2 Review follow-ups: - no unresolved review threads - no related issue; this is the version-only release preparation Residual risk: - all macOS and Windows release targets must build this squash commit so the single-source publisher can pin one verified commit - dev-dep-audit still reports the default branch's existing dependency advisories; this PR changes no dependency and the check is not required

Summary
Persist a terminal assistant result whenever an accepted prompt or compaction marker fails during admission, setup, execution, or cancellation. Bind terminal ownership to the exact submitted trace or active turn parent, and recover the narrow runner-exit race with one bounded retry.
There is no related GitHub issue; this was reported through a PawWork problem report from a production user session.
Why
prompt_asynccan save a user message and detach the session run before provider/model setup completes. A failure therefore left only the user message in history, while the transient bus error was the sole failure signal. Concurrent prompts and cancellation also exposed ownership races: one shared Runner result could leave queued users without their own terminal state, or a latest-message lookup could finalize the wrong turn.The durable contract is now:

Risk Notes
The change touches core session execution semantics. It keeps Runner generic, adds no dependency or migration, and serializes only rare terminal-error writes. The retry remains bounded to one attempt and applies only to non-interrupted traced prompts that the joined run did not cover.
