GitHub tokens limited to repo, gist, and workflow fail PR detail reads because the query selects Team fields requiring read:org or read:discussion. GitHub rejects those selections even with zero requested reviewers, so the existing forbidden-reviewer fallback cannot recover and watches cannot observe checks. This extends the established unreadable-reviewer recovery in #19549 / #19564 to the reproduced INSUFFICIENT_SCOPES response.

Retry that response once with Team metadata excluded. Remember a successful fallback for ten minutes per credential and host, and use it for both detail and review-thread reads. Individual reviewers, the Team type marker, check results, and review decisions remain available. Team names and avatars unavailable to that credential are omitted. Failed retries and unrelated read errors still fail.

Verification:

• Reproduced the exact GitHub scope errors with the existing credential, including first: 0; the conditional Team fragment succeeds with its flag disabled. No credential scopes changed.
• A deterministic HTTP transport regression failed on the unchanged implementation with GitHubApiResponseError / INSUFFICIENT_SCOPES. The final selected run passes 179 tests, including preservation of a failing check, the review decision, reviewer/team presence, cached recovery, and propagation of later failures.
• Format, lint, both Knip passes, GraphQL generation verification, and all 11 affected package typechecks pass. vp run check:changed was attempted but blocked at the Windows ignored-file/pnpm-junction scan tracked in perf(scripts): check:changed on Windows no longer spends minutes walking node_modules (2,500 s → 5.0 s) #32023; its exact selected stages were run serially without altering the checker or its cache.
• Production start server with a disposable home, authenticated WebSocket client, and deterministic GitHub HTTP peer: initial Team-scope refusal retries successfully; pending checks and the individual reviewer remain intact; a check-data refusal still fails. A normal watcher sweep then reads detail/activity/review threads and persists the watched head from null to abc123, with passed: false. No paid provider turn ran. The server was stopped. All six production-file SHA-256 hashes still match this runtime; the follow-up review change only strengthens the existing refusal assertion.

Implemented with OpenAI GPT-6 via the Codex harness.

Approvability

Verdict: Approved at e79ae42

Macroscope's review found this PR approvable — GitHub PR reads can recover from missing organization scopes by omitting inaccessible Team metadata while retaining reviewer and check information. The fallback is credential-scoped and temporary, with no permission expansion or external-data mutation.

Walkthrough

GitHub pull request reads now conditionally request reviewer team details. When GraphQL returns only insufficient-scope errors, the API retries without those details and caches the fallback by credential and normalized host. Reviewer mapping retains __typename to identify team requests.

Changes: Team reviewer scope fallback

Layer / File(s)	Summary
Conditional team reviewer selections packages/source-control-github/src/server/pullRequestReads.graphql, packages/source-control-github/src/server/pullRequestReads.graphql.ts, packages/source-control-github/src/server/pullRequestReviews.graphql, packages/source-control-github/src/server/pullRequestReviews.graphql.ts	PullRequestCore and ReviewThreads conditionally select team reviewer details with teamDetails. Their response schemas allow team fields to be absent when those details are not selected.
Team reviewer identification packages/source-control-github/src/server/gitHubPullRequestJson.ts	Requested-reviewer mapping retains __typename. hasTeamReviewRequest recognizes requests typed Team, including when a login is present.
Scope fallback and read integration packages/source-control-github/src/server/GitHubPullRequestApi.ts, packages/source-control-github/src/server/GitHubPullRequestApi.test.ts	The API retries with teamDetails: false when a successful HTTP response contains only INSUFFICIENT_SCOPES errors. It caches the fallback by host and credential, reuses it for detail and thread reads, and tests fallback reuse and reviewer-refusal handling.

Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.

Cache write happens only after a successful fallback read, but the fallback shares one key across all pull requests.

teamKey is per credential and host. A cached refusal skips Team details for 10 minutes for every repository. This is a deliberate trade-off. A token that gains read:org stays degraded until the entry expires. The behavior is acceptable. Document it in a short comment, because the existing refusedReviewers comment covers only the per-pull-request case.

capturing the failure returned through Effect.flip and verifying its
GitHubApiResponseError tag, status, refusal message, and error type. Also assert
that mockedExecute records the expected two reviewer-retry calls after the
baseline count, using the existing refusedReviewer fixture.
