Summary

Works through the fifteen follow-ups that the review of #1035 left for later. Each one is either implemented or closed with a reason. The owner made four decisions:

  • Item 2 records an override in a bot comment.
  • Item 3 waits for a second maintainer.
  • Item 10 runs the sync every 15 minutes.
  • Item 14 gives the three workflow scripts a coverage floor of their own.

Fixes #1039

The fifteen items

# Resolution
1 Done, differently from the proposal. A local CommonMark scanner would still be an imitation, so the description is now read as GitHub itself renders it (POST /markdown, gfm, this repository as context). html.parser keeps the prose outside <code> and <pre>, and every block boundary becomes a line break. The constructs listed in the issue all resolve as GitHub resolves them: a code span holding <!--, escaped backticks, abrupt comments, fences in quotes and list items, raw <pre>. GitHub's real output for 32 hostile samples is captured in tests/fixtures/github_markdown/renders.json. One behaviour changes: an inline <!-- that never closes is now read, because GitHub shows it as text. The title and the commit messages are read as plain text: GitHub does not render a title as Markdown (an HTML comment or a fence marker shows there as written), and it closes issues from commit messages whatever they look like. The four line-walker readers are gone.
2 Done (owner's choice: bot comment). A new Record dependency override job runs only when dependency-override is added. If a maintainer added it, the job comments with the head commit and the issues linked at that moment; it takes the title and description from the event payload, so an edit a second later is not accepted. The override counts only while the head is unchanged and the linked set is a subset of the recorded one. A new commit or a new link ends it, and the check says why. Only comments by github-actions[bot] count, so a person, or another app quoting someone, cannot forge a record. The required check needs the recorder (if: !cancelled()), so the record exists before the check reads it.
3 Closed with a reason (owner's decision). With one maintainer, code-owner review would only add a bypass to every merge. MAINTAINERS.md now says that adding a co-maintainer turns on Require review from Code Owners for development.
4 Done. When /assign cannot read the dependencies, the reply says so and tells the maintainer to check Blocked by before assigning (DependencyReadError).
5 Done. gh api --include gives the headers. A list ends where GitHub announces no rel="next", so an exact multiple of the page size costs no extra request. Endpoints keep their fixed page=N form, because GitHub's Link URLs use repositories/<id>/… paths outside the allow-list. The bounds that used to stop silently in assign_on_comment.py now warn or fail.
6 Done. Reads are retried (GET, GraphQL queries, renders), 3 tries with 2 s / 4 s back-off. A retry happens on no answer, a 429 or 5xx, or a rate-limited 403, honouring Retry-After and the rate-limit reset up to 60 s. Writes are never repeated. This applies to both scripts.
7 Done (runbook). A Repository automation section in MAINTAINERS.md lists what a rename or a transfer breaks: the github.repository guard, the Actions policy, branch protection and the project-board link. The guard's comment points there.
8 Closed with a reason. No merge queue exists. The same runbook says to add merge_group before enabling one, or the queue waits forever for the required check.
9 Done. Reconciliation prefers the check runs whose pull_requests name this pull request. It falls back to the latest run, since fork runs often name none.
10 Done (owner's choice: 15 minutes). The cron is 2,17,32,47 * * * *; the messages and docs say "within 15 minutes".
11 Done for pull requests; transfers closed with a reason. sync removes blocked from open pull requests (in the reconciliation pass) and from closed ones (the closed list now keeps them). The token cannot write to the repository a transferred issue lands in, so CONTRIBUTING's maintainer notes say to remove the links and the label before transferring.
12 Done. The unblock marker carries when blocked was last added (…@<time>), so an issue unblocked a second time gets a second notice.
13 Done. Label history comes from GraphQL timelineItems(last: 100, itemTypes: [LABELED_EVENT, UNLABELED_EVENT]). The REST event pages are no longer read, so a long history cannot fail the check.
14 Done (owner's choice). A new CI step and two gauntlet lines run the three scripts' own tests under coverage and require 90% across tools/issue_dependencies.py, tools/assign_on_comment.py and tools/triage_gate.py (today 95 / 94 / 100, 96 overall). tests/test_guard_wiring.py pins both lines, and a new test makes sure the full pytest run is not replaced by this subset.
15 Done, except the gh pin. The gh CLI stays unpinned: the scripts use only gh api --method/--input/--include, and downloading a binary in a job that holds a write token adds more to trust than a version drift on GitHub's own runner image costs.

Security notes

  • The recorder job writes, but only comments. It holds contents: read and pull-requests: write, runs only for a labeled event naming the override label, checks out one file from the default branch and executes nothing from the pull request. The required check stays read-only.
  • No change to the Actions policy. Both jobs live in .github/workflows/pr-dependencies.yml, the path the pull_request_target policy already allows.
  • Concurrency moved to the check job. The recorder is never cancelled by a burst of events.

Testing

  • Unit tests: tests/test_issue_dependencies.py and tests/test_assign_on_comment.py cover every item (597 tests across the three workflow-script modules).
  • Live read-only check: run against the API before opening this PR:
    • the new GraphQL label_changes query on an issue and on a pull request;
    • gh api --include parsing of a 200, a 404 and a GraphQL error;
    • Link paging;
    • rendering and reading a description.
  • Review round 1 (CodeRabbit): the title is no longer rendered (it could hide a visible reference), and the full-suite wiring test rejects a narrowed CI pytest command.
  • Full gauntlet: the CLAUDE.md gauntlet passes locally (6,308 tests; every guard green; the new coverage step reports 96%).

After merge

  • Recorder: check it on a real pull request: set dependency-override, see the record comment, push a commit, see the check turn red with the reason.
  • Schedule: confirm the first runs of the new 15-minute schedule.

📝 Walkthrough

This pull request updates issue-dependency parsing, override recording, scheduled reconciliation, assignment API handling, workflow wiring, and separate 90% coverage requirements for three workflow scripts.

Changes: Issue and pull-request automation

Layer / File(s) Summary
Dependency parsing and API handling
tools/issue_dependencies.py, tests/test_issue_dependencies.py, tests/fixtures/github_markdown/renders.json
Dependency extraction uses GitHub-rendered pull-request text, titles, commit messages, and linked-issue data. API handling adds validation, retries, pagination, label timelines, and pull-request-specific check selection.
Override recording and reconciliation
.github/workflows/pr-dependencies.yml, .github/workflows/issue-dependencies.yml, tools/issue_dependencies.py, tests/test_issue_dependencies.py, CONTRIBUTING.md, CHANGELOG.md, MAINTAINERS.md
A record-override job records maintainer overrides against the current commit and linked issues. Reconciliation runs every 15 minutes, removes blocked from pull requests, and uses timestamped unblock markers.
Assignment API handling
tools/assign_on_comment.py, tests/test_assign_on_comment.py
Assignment reads use retries, response headers, pagination metadata, sanitization, and repository-bot filtering. Dependency-read failures receive a distinct error and response.
Coverage checks and workflow guidance
.github/workflows/ci.yml, AGENTS.md, CLAUDE.md, CONTRIBUTING.md, docs/standards/testing.md, tests/test_guard_wiring.py, tests/test_check_ci_failure_masking.py
CI and documented validation commands require at least 90% coverage for the three workflow scripts. Wiring tests verify the coverage commands and unrestricted full-suite execution.

Full details: Description check

Explanation

The description is detailed and directly addresses the pull request objectives. It includes a summary, linked issue, implementation details, testing evidence, security notes, and post-merge checks. It does not use the template's exact Type and Checklist sections, but the required information is substantially covered.

Full details: Linked Issues check

Explanation

Issue #1039 is directly linked and remains open. The reported changes address all fifteen follow-ups. They add GitHub-rendered Markdown handling, override binding to the head and linked issues, dependency-read errors, pagination, transient-read retries, repository automation guidance, check-run selection, a 15-minute schedule, pull-request label cleanup, repeated-unblock markers, bounded label-history reads, and a separate 90% tools coverage gate. The PR records reasons for the owner decisions on code-owner review, merge queues, transfers, and the unpinned gh CLI. The reported tests cover the changed workflow logic and guard wiring.

Full details: Out of Scope Changes check

Explanation

The changes stay within issue #1039. Workflow edits implement dependency checking, override recording, scheduling, and coverage enforcement. Tests, fixtures, documentation, runbook updates, and changelog updates support the fifteen follow-ups. No unrelated implementation is demonstrated.

Full details: Docstring Coverage

Explanation

Docstring coverage is 27.64% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff. Analyzed 199 functions across 6 files. (2 skipped: 2 unsupported.)

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.

Follow-ups for the issue-dependency mechanism that the review of #1035
deferred (#1039):

- Read the title and the description through GitHub's own renderer
  (POST /markdown) and keep the prose outside <code>/<pre>; commit
  messages are read as plain text. Replaces the line-walker readers.
- Record a maintainer's dependency-override in a bot comment (head
  commit and linked issues) from a new "Record dependency override"
  job; a new commit or a new link ends the override.
- /assign says when the dependencies could not be read.
- gh api --include: paging follows Link rel="next", transient read
  failures are retried honouring Retry-After, writes never are.
- Reconciliation prefers check runs tied to the pull request; sync
  removes `blocked` from pull requests; a second unblocking gets a
  second notice; label history comes from the GraphQL timeline.
- Sync every 15 minutes; a coverage floor of 90% for the three
  workflow scripts in tools/; runbook for renames, transfers, merge
  queues and a second maintainer in MAINTAINERS.md.
- Polish: blob/HEAD links, release and limit wording, ANSI and
  invisible characters stripped from logged errors, a scaling ReDoS
  test.

Fixes #1039

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
GitHub does not render a title as Markdown: an HTML comment or a fence
marker shows there as written, so rendering the title could hide a
reference the reader sees. The title is now read as plain text, like
the commit messages (one markdown call fewer per check).

The full-suite wiring test now rejects a CI pytest command narrowed by
a test path or a selection option.
