What changed\n- Adds a central turn-evidence accumulator over the canonical runtime event stream.\n- After tool-using turns, adds a concise completion chip stating how many actions succeeded or failed.\n- Deliberately labels successful actions as evidence only: task results remain agent-reported until an independent verifier exists.\n\n## Why\nA provider urn.completed event alone is not proof that the requested task worked. This gives users a truthful, observable distinction without changing provider behavior, computer control, or retry policy.\n\n## Overlap avoided\n- Does not duplicate PR #58 browser/computer observation guards, PR #37 screen-frame gating, or provider-specific tool handling.\n- Reuses the canonical event fold shared by all drivers.\n\n## Verification\n- corepack pnpm typecheck\n- corepack pnpm test — 65 passed, 39 platform-gated skips\n- corepack pnpm build\n- Focused tests cover action evidence, mixed/failed tools, and no-noise conversational turns.\n\n## Limitations\n- This is completion evidence, not independent semantic verification. A later verifier can feed into the same summary once it has objective criteria or watch-skill proof.\n- No automatic retry is added; failures remain observable and safe.

Summary by CodeRabbit

  • New Features

    • Added activity updates summarizing whether turn-related actions succeeded or failed.
    • Success and failure summaries now reflect the outcomes of multiple actions within a turn.
    • Agent-reported completions are distinguished from independently verified results.
    • Suppressed summaries for purely conversational turns without actionable evidence.
  • Bug Fixes

    • Prevented late notifications after a completed turn from creating duplicate activity events or altering turn state.

Warning

Review limit reached

@carbongotfound, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 56 minutes

Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.
You're only billed for reviews past your plan's rate limits ($0.25/file).

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

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.

Please refer docs for additional details.

📝 Walkthrough

Walkthrough

The server now tracks tool outcomes per turn. It classifies the evidence at turn completion and emits a bot activity message when relevant evidence exists. The Codex driver ignores notifications received after a turn settles.

Changes

Turn verification evidence

Layer / File(s) Summary
Evidence classification contract
server/verification.ts, server/verification.test.ts
Added TurnEvidence, emptyEvidence, and completionEvidence. Tests cover successful, failed, mixed, and conversational turns.
Server evidence lifecycle
server/index.ts
The server records tool starts and outcomes per turn. It converts stored evidence into a completion activity message and clears the state.
Late notification suppression
server/drivers/codex.ts, server/testing/fake-codex-app-server.ts, server/drivers/codex.test.ts
The Codex driver ignores notifications after turn settlement. The fake app server and test cover delayed notifications.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟡 Moderate · up to 971ae

The PR adds turn-evidence reporting, but interrupted turns can remain temporarily active and accept late notifications or requests, which may show misleading activity/evidence or create unanswerable requests. This lifecycle issue should be fixed or explicitly accepted before merge.

The evidence distinction is good, but the current fold can lose or recreate evidence incorrectly. drops successful-action counts whenever the overall turn fails, and late ACP notifications can recreate per-turn state after settlement/cancellation. Please preserve succeeded/failed counts independently of , ignore notifications after the session settles, and add exact-payload tests for failed turns with successful and mixed tool outcomes.

Addressed the requested evidence fixes in the latest commit. Successful and mixed tool counts are now preserved even when the overall turn fails; urnOk only affects the summary status. Codex now ignores notifications after settlement, with a fake ACP regression case. Focused verification and Codex tests pass (4 passed, 9 platform-gated skips), and pnpm typecheck passes.

Addressed the remaining cancellation race: interrupt now marks the turn stopping before kill, and both notifications and server requests are ignored while stopping or settled. The late-event regression now asserts the expected initial command and explicitly rejects late command activity. Verified with typecheck and focused Codex/verification tests (POSIX spawn cases remain skipped on Windows).
