Related to #21359. Now a single commit on main, on top of #21395 (which superseded #21305). The device screenshots below were taken on the #21305 version of the sheet; the row code is unchanged, and after the port the unit test, mobile typecheck, lint and format pass.

Problem

The mobile Background work sheet lists a PR-watch monitor as "Monitor" with a label, so you cannot tell which pull request is being watched or open it.

Fix

A PR-watch monitor row now shows the PR title, the number coloured by state, "Watching · Open/Draft/...", and a checks summary. Tapping it opens the PR on GitHub. Other rows (subagent, command, other monitors) are unchanged, and a link with no snapshot yet still renders and stays tappable.

No contract change: the monitor task id is already pull-request-watch:<host/repo#number>, and the thread shell already carries pullRequests, so the client looks the link up with one shared helper (findPullRequestForWatchTask) next to the code that builds the id. Colours and check icons reuse pullRequestStatus.ts.

Evidence

Tapping the #21305 row on a Galaxy S25 opens the real PR in the GitHub app:

• Unit test for the task-id to PR mapping, including the same number in another repository not matching.
• Mobile typecheck clean for the touched files.
• Verified on a real S25 against a real server.

Not covered: web banner parity (inline link button using the same helper, about 15 lines), and merged/closed/failing-check colours were not captured on device.

Approvability

Verdict: Needs Human Approval

Macroscope's review found this PR requires human approval — This adds a new mobile background-work screen and interaction flow, including PR metadata rendering, child-thread navigation, and opening PRs externally. The feature changes existing background-status behavior and introduces substantial user-facing runtime logic, so it merits human review.

Walkthrough

The shared package maps pull-request watch-task IDs to linked pull requests. The mobile background work sheet uses matching links to display pull-request details and available status indicators, and can open the pull request externally.

Changes: Pull-request monitoring

Layer / File(s)	Summary
Watch-task lookup packages/shared/src/orchestrationV2PendingBackgroundWork.ts, packages/shared/src/orchestrationV2PendingBackgroundWork.test.ts	Adds findPullRequestForWatchTask and uses shared helpers to identify watched pull requests and build watch-task IDs. Tests cover matching links, unknown IDs, repository mismatches, and dismissed duplicates.
Mobile monitor rows apps/mobile/src/features/threads/ThreadBackgroundWorkSheet.tsx	The sheet renders a pull-request row for matching tasks and retains the existing row for other tasks. The pull-request row shows available details and status, supports missing snapshot data, and opens the URL externally with an alert on failure.

Merge Risk: Low · up to 819db

Some rows may fail to open the watched PR or omit its available checks summary.

Security architecture risk: Low · up to 5da51

The change adds a tap target for already linked pull requests without demonstrating broader access or new privileges. Handling of unexpected link destinations remains partly unverified.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — The demonstrated exposure is user-triggered navigation from a displayed thread into the device's URL-handler boundary. Row rendering does not automatically open links. Accepted schemes and the authority exercised by downstream handlers remain outside verified coverage.

Security Findings and Attack Paths

• inferred — No materially new attacker-controlled path was established. Before this PR, linked-pull-request menus already offered an unconditional browser action for the same stored URL, including snapshotless links. The new monitor row adds another trigger for that existing handoff, not a new URL producer or privileged operation.

Trust Boundaries and Controls

• observed — Task matching establishes correspondence with a thread's linked pull request, not destination safety. The unchanged link schema accepts a nonempty URL, and tryOpenExternalUrl forwards it directly to Linking.openURL without application-level scheme or authority validation. Its pull-request target labels error reporting rather than enforcing a navigation policy.

Hardening Proposals

• proposed — As separate hardening of the existing navigation boundary, consider enforcing expected web URL schemes for pull-request destinations, with explicit support for enterprise hosts. This is not a verified vulnerability introduced by this PR.

Open PR-watch rows with repositoryWebUrl

ThreadPullRequestLink.url can contain an API or synthesized URL. The row passes that value unchanged to Linking.openURL, so an API URL can open the API response instead of the pull request, while an unsupported clone URL can fail and show “Unable to open PR”. Use repositoryWebUrl when present and retain url as the fallback for older links.

Suggested fix

-        void tryOpenExternalUrl(link.url, "pull-request").then((opened) => {
+        void tryOpenExternalUrl(link.repositoryWebUrl ?? link.url, "pull-request").then((opened) => {

Show checks for closed and merged PR-watch rows too.

The snapshot?.state === "open" guard hides a checksState that the server forwards for any PR state. The checksState schema allows non-null values for every state, and the server copies it without a state check. A closed or merged watch row can therefore have a checks value that the row drops. The general PR rows in this repository show checks for every state. Remove the state check so the row shows the checks summary whenever checksState is non-null. The status line is separate and does not change.

Suggested fix

   const checks =
-    snapshot?.state === "open" && snapshot.checksState
+    snapshot?.checksState
       ? pullRequestChecksStatus(snapshot.checksState)
       : null;

Re CodeRabbit review 5638150863 (outside-diff comments), both left as is:

1. repositoryWebUrl for opening the row: per packages/contracts/src/threadPullRequest.ts that field is the repository's browser or clone URL, not the pull request's, so opening it would land on the repo instead of the PR. No other client opens PRs through it. url stays.
2. Checks on closed or merged watch rows: a watch ends when its PR merges or closes, so these rows only describe open PRs in practice; the open-only guard keeps a stale checks badge off a PR that is already done. Not changing it in this PR.
