Review comments at @tests/test_guard_wiring.py:
- Around line 399-400: Strengthen the assertion in the test around _run_scalars
for ci.yml so it validates the pytest command runs the full suite, rejecting
commands with narrowed test paths or selection options while preserving the
existing pytest-command check.
Review comments at @tools/issue_dependencies.py:
- Around line 480-481: Update the pull-link collection loop to process
pull.title directly with linked_issues, without prose or render, while
continuing to process pull.body through prose(render(...)); preserve the
existing repo argument and union behavior.

…them 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. Refs #1039 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

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:

The fifteen items
POST /markdown,gfm, this repository as context).html.parserkeeps 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 intests/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.dependency-overrideis 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 bygithub-actions[bot]count, so a person, or another app quoting someone, cannot forge a record. The required checkneedsthe recorder (if: !cancelled()), so the record exists before the check reads it.development./assigncannot read the dependencies, the reply says so and tells the maintainer to check Blocked by before assigning (DependencyReadError).gh api --includegives the headers. A list ends where GitHub announces norel="next", so an exact multiple of the page size costs no extra request.
