Widen the Copilot Bot ID Lookback Past a Long Outage - #986
Merged
Conversation
HISTORY_PRS (the 20 most-recently-updated pull requests) is the window copilot_history reads the Copilot reviewer's own activity from, feeding both the auto-request bot id and the repo-wide quota signal. An outage that outlasts that window leaves every one of those PRs silent, so both readings fell back to blind polling for the rest of the outage with no way to tell it apart from a repository that has simply never seen a Copilot review (#985, reproduced on PRs #981-984). copilot_history now retries once at a wider HISTORY_PRS_WIDE (100, GitHub's own per-connection ceiling) whenever the narrow window comes back with nothing at all, and only then. Q_BOT_ID takes its PR count as a GraphQL variable instead of a baked-in literal, so the narrow and wide reads share one query text. Also adds a truncation guard for Q_FULL's own reviewThreads(first:100), which carried no hasNextPage tracking at all: threads=/unresolved= now print a trailing + and a THREADS TRUNCATED block rather than silently undercounting past 100 threads (#973).
📝 WalkthroughWalkthroughThe review flow detects 100-thread query truncation and reports incomplete counts. Copilot history lookup retries with a 100-PR window when the 20-PR window has no activity. Tests cover both behaviors. ChangesReview completeness
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to This PR widens the Copilot lookback and adds truncation signaling, but the current implementation can still miss the reviewer identity when the narrow history contains only comments and can present an incomplete total-thread count as complete on the reply path. That may cause unnecessary polling and misleading thread totals, so the PR is not merge-ready until these bounded correctness issues are addressed. Sequence Diagram(s)sequenceDiagram

CodeRabbit (PR #986): unresolved= is drawn from the same truncated threads list threads= already marks, so a cut page can hide an open thread exactly as easily as a resolved one. It now carries the same trailing + marker. qodo (PR #986): dropped the two type: ignore[arg-type] suppressions in the new widen tests by typing the recorder list list[object] instead of list[int], which needs no suppression at all rather than an explained one.

qodo flagged two semicolons in #986's new prose (PR #991's promotion review) that violate the fleet's no-semicolon-in-prose rule (comment-and-doc-style). Recast each as two sentences: - `request_copilot_review`'s no-bot-id fallback message - the `THREADS TRUNCATED` digest block Not squashed into #986 since it already merged; this is a small follow-up onto develop. <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **Style** * Improved punctuation in diagnostic messages for clearer readability. * Clarified the thread-truncation warning and pagination instruction. <!-- end of auto-generated comment: release notes by coderabbit.ai -->

Promotes #986 (issues #985, #973) to `main`. ## What - `copilot_history` widens its Copilot-reviewer-bot-id/quota lookback from 20 to 100 most-recently-updated pull requests once the narrow window comes back with no reviewer activity at all, so a long outage no longer reverts `wait` to a full blind poll on every call (#985). - `Q_FULL`'s `reviewThreads(first:100)` now tracks `hasNextPage`, and `threads=`/`unresolved=` print a trailing `+` with a `THREADS TRUNCATED` block when a pull request carries more than 100 review threads, rather than undercounting silently (#973). ## Review PR #986 review loop: CodeRabbit and qodo reviewed, three findings raised and closed (two fixed, in cbb1bbc; one declined with evidence of pre-existing precedent in the file, resolved with authorization). Copilot's own review account is in the fleet's known repo-wide quota- exhausted state (confirmed live via the fixed `wait` itself, in 6s rather than the ~45-minute blind poll the unfixed version would have spent), so this proceeded on the other two reviewers' coverage per standing precedent. <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **New Features** * Review status now indicates when thread results are incomplete, including marked thread and unresolved counts. * Added guidance to use the paginated reply path when additional review threads are available. * Copilot activity searches can expand from the latest 20 to the latest 100 pull requests when no activity is found. * **Bug Fixes** * Improved handling of empty Copilot history and missing bot identifiers. * Added coverage for paginated threads and expanded history searches. <!-- end of auto-generated comment: release notes by coderabbit.ai -->

Fixes the three findings issue #1010 grouped as "lower priority than data integrity, but confirmed real and cheap to fix": 1. **Nested-bracket link-label regex gap** (PR #913): `spec/validate.py`'s and `spec/audit.py`'s `[^\]]*`-based link regexes stopped at the first `]`, so `[API [docs]](url)` passed both the registry description gate and `strip_md_links()` undetected. Replaced with a balanced bracket/paren scanner in both files. 2. **README PATH-persistence self-contradiction** (PR #964): the pre-commit snippet's README claimed `uv tool install` gives an unconditionally PATH-available command, contradicting the next sentence's own conditional-PATH guidance. Applied CodeRabbit's proposed wording. 3. **Quota-widening-only-when-empty gap** (PR #986): `copilot_history()` only widened past `HISTORY_PRS` when the narrow window came back fully empty, so a narrow window carrying only a Copilot comment (no formal review) returned early with no usable bot id, leaving a review just outside the window permanently unread. Widening is now keyed on whether a usable bot id was found, not on emptiness. Each fix carries a regression test. Full suite (849 tests), ruff format/check, mypy, prose_lint, and repo_gate (eol/eol-coverage) all pass. Closes #1010. 🤖 Generated with [Claude Code](https://claude.com/claude-code) <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **Documentation** * Clarified installation guidance for persistent tools and independently running hooks. * **Bug Fixes** * Improved review history detection when recent activity contains comments but no usable review information. * Enhanced Markdown link validation for nested and escaped brackets and parentheses, while safely ignoring unbalanced links. * Improved validation performance for descriptions containing many unmatched brackets. * **Tests** * Added coverage for widened review-history searches and complex Markdown link formats. * Added regression coverage for large, malformed link patterns. <!-- end of auto-generated comment: release notes by coderabbit.ai -->

What
copilot_historyreads the Copilot reviewer's own review and commenthistory from the repository's 20 most-recently-updated pull requests
(
HISTORY_PRS), feeding bothwait's auto-request bot id and itsrepo-wide quota signal. An outage that outlasts that window leaves
every one of those pull requests silent, so both readings fall back to
blind polling for the rest of the outage with no way to tell that
outage apart from a repository that has simply never seen a Copilot
review.
Reproduced today on PRs #981-984: the fast exit-46/47 quota detection
worked for the first two waits, then the 20-PR window emptied out and
every wait after it fell back to a full ~2700s blind poll before
reporting
PENDING.Fixes #985:
copilot_historynow retries once at a widerHISTORY_PRS_WIDE(100, GitHub's own per-connection ceiling) wheneverthe narrow window comes back with nothing at all, and only then, so
the ordinary case still costs one call.
Q_BOT_IDtakes its PR countas a GraphQL variable instead of a baked-in literal, so the narrow and
wide reads share one query text.
Also addresses #973 in the same pass, since it sits in the same
digest/
Q_FULLcode the widen fix touches:reviewThreads(first:100)carried no
hasNextPagetracking at all, so a pull request with morethan 100 review threads silently undercounted
threads=/unresolved=with no signal anything was cut.
threads=now prints a trailing+and a
THREADS TRUNCATEDblock names the gap, rather than a fullcursor-paginated read of the connection (the heavier of the two fixes
the issue suggested), since the tracked reviewers on this repository
have never come close to 100 open threads on one pull request.
