Problem

When GitHub denies a pull-request read, rearming the watch or restarting the server can repeat the same blocker notification. Alternating permission failures can also repeatedly wake the agent without new PR information.

Reproduction: arm a PR watch, return a forbidden or unauthenticated read, then rearm or reconstruct the reactor against the persisted watch. Before this fix, unchanged failures can emit another blocker wake. An incomplete remarks read between access failures can also incorrectly clear the saved blocker.

Change

Persist the first access blocker until a complete detail and remarks read succeeds, suppress repeated permission notifications across restart and rearm, and keep safe probes running so access recovery resumes normal watching. Preserve real PR activity and the concurrent user Stop guard. Incomplete remarks retain the blocker while genuine check changes are still reported. A later failure after complete recovery begins a distinct notification episode.

Scope and approval

This is submitted under CONTRIBUTING's exception for a small, focused fix of an obvious bug, without a prior triaged issue or maintainer approval. The defect is repeated delivery of an unchanged host-access blocker, reproducible through the existing watch API with no new PR activity. The four changed files contain only the persisted blocker, its existing watch lifecycle handling, and behavioral regressions. The change preserves the current PR notification workflow, comment watermarks, and user Stop behavior; it adds no feature or configurable product default.

Verification

On reviewed head 3eff1b3200, vp run check:changed passed format, lint, both knip checks, GraphQL generation, typechecking for 36 packages, and 142 tests across six files. The original regressions failed before the fix. The follow-up's incomplete-remarks phase failed five access-failure cases before the correction, then passed while retaining checks-passed delivery and suppression of repeated access notices.

Ponytail review found the change lean. Spec and Sol reviewed the complete current diff against a9e709f15f825cacac1b6d665fa1920c328d68b7, including the CodeRabbit follow-up, with no actionable findings. The initial change had completed three Sol rounds; the follow-up has one clean review. No correctness finding remains locally open.

All 26 GitHub checks passed on preceding head 2975e02, including build/types, web and server tests, and release smoke. CI and CodeRabbit must rerun on this new head. Installed-runtime behavior remains unverified.

Implemented with GPT-6.1 Sol through the Codex harness.

Walkthrough

Pull-request watches now retain read-blocker state across restarts. After repeated forbidden or unauthenticated read failures, the reactor records the affected operation and sends a failure notification while keeping the watch active.

Changes: Pull-request watch read blockers

Layer / File(s)	Summary
Watch blocker state and lifecycle packages/contracts/src/threadPullRequest.ts, apps/server/src/orchestration-v2/PullRequestWatchReactor.ts, apps/server/src/orchestration-v2/Orchestrator.ts	The watch contract adds optional readBlocker. Watch equality compares it, and a new watch copies it from the ended watch when present.
Read failure handling and coverage apps/server/src/orchestration-v2/PullRequestWatchReactor.ts, apps/server/src/orchestration-v2/runtimeLayer.test.ts	The reactor prioritizes activity access failures in the specified case. After the failure limit, forbidden or unauthenticated failures set a blocker and send a failure notification while the watch remains active. Tests cover failure types, restart behavior, incomplete remarks, and recovery.

Minor · Functional Correctness · Quick win

Keep the blocker until remarks are complete.

If remarks pagination fails or is incomplete, evaluation removes readBlocker. Eight subsequent access failures can then send the blocker notification again without a complete read. Preserve the blocker while still reporting detail changes.
