fix(server): report PR access blockers once until recovery - #32694
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.
It looks like this branch is under active development. To avoid overwhelming you with review comments due to an influx of new commits, CodeRabbit has automatically paused this review. You can configure this behavior by changing the reviews.auto_review.auto_pause_after_reviewed_commits setting.

Walkthrough
Pull-request watches now record access-read blockers after repeated forbidden or unauthenticated failures. The blocker persists through watch transitions, and queued wakes are checked against the current watch and blocker state.
Changes: Pull-request watch read blockers
Layer / File(s)
Summary
Watch blocker state and lifecycle packages/contracts/src/threadPullRequest.ts, packages/contracts/src/orchestrationV2.ts, apps/server/src/orchestration-v2/PullRequestWatchReactor.ts, apps/server/src/orchestration-v2/Orchestrator.ts
The watch and monitor notification contracts add optional readBlocker. Watch equality compares the blocker. New watches inherit it from ended watches, and wake stamps carry and validate it against current watch state.
Read failure handling and coverage apps/server/src/orchestration-v2/PullRequestWatchReactor.ts, apps/server/src/orchestration-v2/runtimeLayer.test.ts
The reactor selects read failures according to detail and activity outcomes. After eight consecutive forbidden or unauthenticated failures, it records the blocked operation and emits a failure notification while keeping the watch active. Tests cover blocker persistence, incomplete remarks, recovery, and repeated failures.
Queued wake revalidation apps/server/src/orchestration-v2/Orchestrator.ts, apps/server/src/orchestration-v2/runtimeLayer.test.ts
Wake validation rejects blocker-stamped wakes when the active watch is absent, its blocker differs, or the snapshot ends the watch. Tests cover active and restarted watches, recovery, a new outage, stopping, and a newer head.

pingdotgg/t3code#27945: This change updates the read-failure notice path for forbidden or unauthenticated reads. The issue’s closed-PR terminal handling is not changed, so the reported behavior is only partly addressed.
pingdotgg/t3code#22966: This change keeps watches active after repeated forbidden reads and emits a blocker notice. It does not return the rest of the pull request with checks unavailable.
The change reports a pull-request access blocker once and keeps the watch active until access recovers. A queued blocker notice is now discarded when access has recovered or the blocker has changed. No actionable merge risk remains from this review.

Explanation
The description follows the template's main sections (Problem, Change, Scope and approval, Verification). The Problem and Change sections are clear and specific. Scope cites the small-bug-fix exception and explains why it applies. Verification gives concrete commands, head SHAs, and results, and it states what is unverified. The template's optional agent-attribution line is present. The description does not include the template's before/after evidence, but that applies only to UI changes, so this is not a gap here.

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.

merged current main without rebasing and preserved both permission-blocker deduplication and terminal-pr handling when activity reads fail.
addressed both queued-notice findings: each access outage has a unique stamp, so its queued notice survives stop/rearm and head changes while access remains blocked, and is cancelled after recovery or a later outage. the existing queue test table covers these cases. three regressions failed before the fix and pass after it. the earlier incomplete-remarks finding remains addressed.
