Problem

When a watched PR merged, watch_pull_request ended the watch without telling the agent. On #26248 the agent kept telling Julius it was still watching CI after he had merged it, and a later unwatch_pull_request returned wasWatching: false. Two paths ended a merge silently: a link snapshot that already said merged ended the watch without reading the host, and a read that said merged ended it without a wake. A close already woke the agent.

Fix

A merge or close wakes the agent once, then the watch ends. A merge names the base branch, the merge commit, and who merged it when the host reports that, for example: "Pull request #26248 (…) was merged into main by juliusmarminge as 3b2f958, so T3 Code stopped watching it." A close says "closed without merging" and tells the agent to watch again if it reopens.
A merged snapshot now gets one read before the watch ends, so the wake can carry the merge commit. GitHub's watch fingerprint includes the PR state, and other hosts reread when the snapshot changes, so a merge still triggers that read.
PullRequestDetail gains optional mergeCommitSha and mergedBy:
- GitHub: mergeCommit and mergedBy in the detail query.
- GitCafe: mergeResultOid, or providerMerge.mergeCommitOid for a merge made on GitHub. GitCafe exposes only merger actor IDs, and they are empty on GitHub-routed merges, so it names no merger.
- Forgejo: merge_commit_sha and merged_by.
No host puts the closer on the PR itself, so a close names nobody.
A reopened PR is not watched again by itself. The close wake tells the agent to call watch_pull_request, and the new watch resumes from what the old one reported.
The user guide says a merge or close wakes once and ends the watch. The tool descriptions are unchanged, so the agent context budget stays flat; the wake itself tells the agent the watch ended.
#26395 already stops a merged PR from holding its thread before the next sweep. That stays, since the merge wake starts its own run.

Verification

New tests, each failing on main:

runtimeLayer.test.ts "wakes once when a watched pull request merges, naming the merge commit": main sends no wake (expected [] to deeply equal [ '#15: merged, stopped watching' ]).
runtimeLayer.test.ts "a pull request closed, reopened, and then merged wakes once for each end": main wakes for the close, then ends silently once the snapshot says merged.
pullRequestWatch.test.ts covers the message wording; the GitHub, GitCafe, and Forgejo detail-read tests cover the merge commit and merger, which are undefined on main.

Field names were checked against live APIs: GitCafe GET /repos/pingdotgg/t3code/pulls/26248 (providerMerge.mergeCommitOid) and Codeberg's forgejo/forgejo PR 15050 (merge_commit_sha, merged_by). vp run check:changed passes.

Approvability

Verdict: Approved at a0f1bb8

Macroscope's review found this PR approvable — Watched pull requests now wake the agent once when merged, including available merge metadata, then stop watching. The change is confined to explicitly enabled watches and retains existing inactive-thread and watch-identity safeguards.

Walkthrough

Source-control adapters now expose merge commit and merger details. Pull-request details carry that metadata into the watch reactor, which sends a terminal message and ends watches when pull requests merge or close.

Changes: Pull request watch lifecycle

Layer / File(s)	Summary
Provider merge metadata `packages/source-control-core/src/server/PullRequestProvider.ts`, `packages/source-control-forgejo/src/server/forgejoPullRequestJson.ts`, `packages/source-control-forgejo/src/server/ForgejoPullRequestProvider.ts`, `packages/source-control-forgejo/src/server/ForgejoSourceControlProvider.test.ts`, `packages/source-control-gitcafe/src/server/gitCafePullRequestJson.ts`, `packages/source-control-gitcafe/src/server/GitCafePullRequestProvider.ts`, `packages/source-control-gitcafe/src/server/GitCafePullRequestProvider.test.ts`, `packages/source-control-github/src/server/pullRequestReads.graphql`, `packages/source-control-github/src/server/pullRequestReads.graphql.ts`, `packages/source-control-github/src/server/gitHubPullRequestJson.ts`, `packages/source-control-github/src/server/gitHubPullRequestJson.test.ts`, `packages/source-control-github/src/server/GitHubPullRequestApi.test.ts`	Provider contracts and adapters now expose merge commit and merger data. GitHub query schemas and selections include the merge fields, and provider tests cover merged pull-request details.
Pull-request detail propagation `packages/contracts/src/pullRequest.ts`, `apps/server/src/pullRequest/PullRequestService.ts`	`PullRequestDetail` now has optional merge commit and merger fields. The service copies available values from provider details.
Terminal watch messages and lifecycle `apps/server/src/orchestration-v2/PullRequestWatch.ts`, `apps/server/src/orchestration-v2/PullRequestWatchReactor.ts`, `apps/server/src/orchestration-v2/pullRequestWatch.test.ts`, `apps/server/src/orchestration-v2/runtimeLayer.test.ts`, `packages/shared/src/orchestrationV2PendingBackgroundWork.ts`, `docs/user/source-control.md`	Merged and closed pull requests now end watches through a shared message and notification path. Regression tests cover terminal notifications, reopening, and link synchronization; the documentation and comment describe the updated lifecycle.

Merge Risk: External image Moderate · up to a0f1b

Watched pull requests may still fail to wake the agent when auto-settlement on merge removes the watch first. Coordinate settlement with the merge wake and add a test for it before merging.

Full details: Title check

Explanation

The title "fix(server): watched PRs wake the agent when they merge" matches the main change: a merge now wakes the agent once before the watch ends, which the raw summary and objectives both describe. It names the server scope and the conventional commit type. It leaves out the close wake and the new merge metadata, which is acceptable since the title need not cover every detail.

Full details: Description check

Explanation

The PR description follows the repository template closely. It has Problem, Fix (Change), Verification, and an agent attribution line. The Problem section explains the silent merge end and the close behavior, with reproduction context from #26248. The Fix section describes the wake-once behavior, the new PullRequestDetail fields per provider, and the reopen behavior. The Verification section names specific new tests, states the expected failure on main, and reports that vp run check:changed passes. The Scope and approval section is missing. The template requires a link to a triaged bug issue or a discussion with explicit maintainer approval, or an explanation of why a small obvious fix qualifies without one. The description does not link an issue or discussion, and it does not explain the exemption. The PR objectives say Julius Marminge took over the PR, but the description does not cite any approval. The Verification section also does not describe any manual check of the UI or user-visible message, but the template only requires that for UI changes, and this change is server-side text, so that is not a gap. The author should add the Scope and approval section with the triaged issue or maintainer approval comment, or a justification for the small-fix exemption. The description also says the close wake tells the agent to call watch_pull_request, which is consistent with the code summary. The model and harness line is present, which satisfies the template's agent attribution rule.

Resolution

Add a "Scope and approval" section. Link the triaged bug issue or the discussion that has explicit maintainer approval of the direction and scope, and include the approval comment. If no issue or discussion exists, explain why this change qualifies as a very small, focused fix of an obvious bug. The change adds optional fields to PullRequestDetail across GitHub, GitCafe, and Forgejo, and it adds a new wake behavior. That goes beyond a trivial fix, so an approval link is likely required.

Isolate the two observation cases.

The cases share layerTest but reuse the thread and command IDs. The second case replays the create and watch commands, then can pass using the first case’s notification without testing its own observation path. (raw.githubusercontent.com)

Use distinct thread and command IDs for each case, or provide a fresh layer per case. As per path instructions, “Backend behavior changes should have focused tests for behavior that can break.”

Note

Claude Opus 5.5 responding on behalf of Melvin

This PR alone would not have woken our thread: when the thread has a completed run, auto-settlement removes the watch before the reactor reads the merged snapshot. #25181's awaitsMergeWake guard in ThreadSettlementService.ts covers that path; this PR does not touch settlement.

Observed on server v0.1.6 (Linux, Claude Code provider, GitHub, Mergify merge queue), from the thread's persisted events and the service journal. Times are relative to the merge:

Time	Event
-11m25s	Required checks passed. A wake started a run, which completed 9 s later. The thread was idle from then on.
0	Mergify squash-merged the PR.
+8.97s	`thread.pull-request-link-updated` persisted the merged snapshot. The watch was still set.
+9.04s	A `server:auto-settle:` command set `settledOverride: "settled"` and moved `watch` to `endedWatch`. It created no notification and no run.
+42.6s	The reactor logged `pull request watch ended` with `reason: "stopped"`, `wakes: 1`, `reads: 6`.

The reason is stopped, not merged: the next sweep found no watch at all. With this PR applied, that sequence is unchanged. endsWithoutRead would return settled if it ever saw the target, and finished never runs because the target is gone. Settlement keys on the snapshot update (resolveAutoSettlementAt on main, with sidebarAutoSettleOnMerge defaulting to true), and the settle command strips active watches.

The new runtimeLayer.test.ts cases use a thread that has never run, so they do not cover this race. Suggested coverage: the same "seen by the link's sync" case after one completed run, with default settings, asserting one merge wake and that the thread settles only after that wake's run.

Verified: the event sequence and the log line above, and that main (as of dabab454) has no settlement guard for a watched merge. Not verified: a build with this PR applied.

Prevent auto-settlement before the merge wake.

If a merged snapshot is synced before the watch sweep, auto-settlement can remove the watch without a wake. Default settings enable settlement on merge.

Keep the thread from auto-settling until the merge wake is recorded and its run finishes. Add a runtime test with a completed run, default settings, and a synced merged snapshot. Assert one merge wake and settlement after that wake’s run.

This test locks down notification copy rather than behavior, which the testing rules explicitly exclude. Could you delete it and keep the lifecycle coverage in the reactor tests?

We reviewed a0f1bb8 against a real case: a thread watching a GitLab MR that another account merged. It ended silently on main and wasn't settled. Tracing that case through this head gives exactly one wake ("was merged into main, so T3 Code stopped watching it"), and the two new runtimeLayer.test.ts cases cover both silent paths. Two things worth a look before merge:

A merged PR whose reads keep failing now polls forever. Before this PR, endsWithoutRead ended a merged-snapshot watch with no read. Now the watch has to read first, and a read that fails with reason: "failed" resets the counter and keeps the watch (PullRequestWatchReactor.ts:501-504). So a host that keeps returning an unclassified error (GitLab's provider falls back to failed, GitLabPullRequestProvider.ts:110) means a fresh allowStale: false detail read every sweep, with no wake and no end. One option is to count failed toward READ_FAILURE_LIMIT when every target's snapshot already says merged, and fall back to a plain merge wake when the limit is hit. No test covers read failures on a merged snapshot.
GitLab merges name no merger or commit. The new fields are wired for GitHub, GitCafe and Forgejo, but RawMergeRequestSchema and GitLabMergeRequestDetail don't carry them, so a GitLab wake says only "was merged into main". The MR API returns merge_user (merged_by is deprecated) and merge_commit_sha, plus squash_commit_sha for squash merges, where merge_commit_sha can be null. This could be a follow-up; the wake is still correct without them.

Minor: the merger's login goes into the wake text unbounded. Forgejo's forgejoActor and the GraphQL MergedByUser take any string. That matters mostly for self-hosted Forgejo. Comment bodies already reach the agent the same way, so it's low priority, but capping its length and stripping control characters at decode would cost little.

The settle-before-read race that @melv-n raised above still drops the merge wake here (Orchestrator.ts:3203-3214); that's #29896.

Reviewed with three GLM 5.3 Flash passes (security, simplification, correctness) plus a read by Claude Opus 5.5, in Claude Code running in T3 Code.
