Problem

Fixes #30530. When one check fails early, the watch wakes the agent with "checks failed". If the remaining checks then finish, no further wake arrives: checks-passed and the owed settled wake both require zero failures, and checks-failed fires only for newly failed checks. The thread waits until a push, comment or conflict.

Change

The watch remembers whether any check was still pending (checksPending, optional, absent on older watches). When checks go from pending to none pending, failures remain and nothing newly failed, it sends one checks-settled wake ("All N checks have finished; M remain failed or need attention"). The field is kept when a PR is watched again. One sentence in the source-control user guide lists the new wake reason.

Scope and approval

This is the defect reported in #30530; the issue describes the root cause in evaluatePullRequestWatch and the expected behavior (one more wake when the remaining checks finish). It adds no timer or new alert policy.

#33214 adds a checksPending field with the same meaning (any check on the head still running). I used the same name and meaning so the two can be reconciled; whichever lands second should use the other's field.

Verification

pullRequestWatch.test.ts "reports completion…": on main it fails with expected [] to deeply equal [ { kind: 'checks-settled', … } ] (no wake); passes with the fix.
runtimeLayer.test.ts "finishes owed…": on main the re-watch keeps no pending state (expected undefined to be true); passes with the fix.
vp run check:changed passes.

Not checked: a live GitHub run against this branch. We hit the bug in practice (threads waiting after green CI); a build with the same fix has been running locally.

Approvability

Verdict: Approved at aac161f

Macroscope's review found this PR approvable — PR watches now wake the agent when remaining checks finish after an earlier failure, explicitly noting that failures remain. The change is limited to activated watches and leaves polling, merge permissions, and product defaults unchanged.

Thanks @griffemi for the fix and regression coverage. #25540 by @aglowienka addresses the same missed wake after an early failure, with regression tests, runtime verification, and passing checks; it also ends the watch after the final notice. We are keeping that earlier PR, so I am closing this duplicate. Please share any concerns about the different watch-ending behavior there.

Ggriffemi18h ago

Thanks, makes sense to keep the earlier PR (#25539 here). Ending the watch after the final notice works for us. Closing as a duplicate.

JJulius Marminge12h ago

Reopened: this is the newer, live fix for the same missed checks-finished wake, while the earlier PR has gone stale. Thanks @griffemi for the focused fix and regression coverage.

Note

Written by claude-opus-5-5 on behalf of Maria

Merged current main (merge commit, no rebase) to clear the conflict with the approval-gate work in pullRequestWatch.ts and the watch docs.

Conflict resolution, keeping both sides:

checks-settled now reads the non-placeholder checks list from main instead of detail.checks.
Checks awaiting approval (action-required, or a held awaitingApproval key) count as unfinished, so the "all checks have finished" wake does not fire while a run waits for a maintainer.
newlyFailed moved out of scope on main, so the guard now skips the settled notice when this sweep already reported checks-failed or checks-passed. Same behavior as before.
Docs keep main's approval wording plus this PR's sentence.

vp run check:changed passes (format, lint, knip, typecheck of 37 packages, 7 test files / 167 tests).

Walkthrough

The pull-request watch now tracks whether checks remain pending. When they finish with failures remaining, it reports a checks-settled event. The watch preserves this state across evaluations and restarts.

Changes: Pull request check completion

Layer / File(s)	Summary
Track check state and report completion `packages/contracts/src/threadPullRequest.ts`, `apps/server/src/orchestration-v2/pullRequestWatch.ts`, `apps/server/src/orchestration-v2/pullRequestWatch.test.ts`, `docs/user/source-control.md`	The watch records pending-check state and emits `checks-settled` when checks finish with failures remaining. The event includes total and failed-check counts, has display text and a notification label, and is covered by a regression test. The documentation adds the corresponding wake-up condition.
Preserve pending state across watch lifecycle `apps/server/src/orchestration-v2/Orchestrator.ts`, `apps/server/src/orchestration-v2/PullRequestWatchReactor.ts`, `apps/server/src/orchestration-v2/runtimeLayer.test.ts`	New watches carry forward the previous ended watch’s pending-check state when defined. Watch equality includes the field, and runtime tests check that it persists across reactor and watch restarts.

The new wake for finished checks can fire early when GitHub's approval data cannot be read. The final wake is then skipped, which is the case this change is meant to fix. Keep the pending state while the read is incomplete before merging.

Explanation

The description covers the problem, change, scope, and focused verification. It links the reported defect and explains why the change does not add broader alert behavior. It also states that a live GitHub run was not checked.

Full details: Linked Issues check

Explanation

[ #30530 ] evaluatePullRequestWatch records pending state and emits one checks-settled change when pending checks finish while failures remain, unless the same evaluation already reports failed or passed checks. It preserves the state in the next watch. The watch schema adds optional checksPending, and the re-watch logic retains it. The regression test covers the early-failure/remaining-check completion case and checks that the wake does not repeat. The message and user guide describe the new wake.

Full details: Out of Scope Changes check

Explanation

The changed state, watch persistence, equality check, regression tests, and user-guide text all support [ #30530 ]: they implement or verify the settled-check wake and its delivery. The supplied diff summary shows no unrelated behavior or policy changes.

Preserve pending state when the check read is incomplete.

If a previous sweep saved checksPending: true, a read with one failed check, one finished check, and a placeholder can reach this block: passedNow is false, so the guard at Line 111 does not exclude the unread result. The placeholder is removed from checks, so pendingNow becomes false and the watch announces completion. When a later complete read shows that all checks have finished, the saved state is already false and the intended wake does not occur. Keep the pending state until the read can establish that no checks remain pending.
