Two review findings on the issue gate, with a common root cause.
MARKER is an invisible HTML comment, so anyone who can comment on a
public repository can paste it. findNotices accepted any comment
containing it, so a third party could post one on someone else's pull
request: runGate posts a notice only when none exists, so the author
would never be told, and runSweep would then measure the 72-hour grace
window from the stranger's timestamp and close them unwarned. Notices now
require bot authorship.
The stale-draft sweep re-listed the gate's exemptions and had lost the
bot case, so a bot's long-lived draft was closable despite checkGate
exempting bots. Both callers now share one exemptReason(pr) rather than
keeping parallel lists that drift.
Not changed: closingIssuesReferences(first: 20) truncation. It needs a
pull request with 21+ closing references where only a later one carries
the label, and the outcome would be a label plus the grace window, not a
close.
Coverage goes 11 -> 20 cases, including the stale-draft close path, which
had none. Both fixes were confirmed to fail their tests when reverted.

Addresses review feedback on #1041.
The gate now reads GitHub's resolved closing references
(closingIssuesReferences) instead of regex-parsing the pull request body,
so an issue linked through the sidebar Development panel counts, and a
bare `#123` mention no longer does.
It also no longer closes on the pull request event. It labels and
explains; pr-sweeper.yml re-checks every six hours and closes only what is
still failing 72 hours after the notice. That re-check is load-bearing:
linking an issue via the sidebar fires no webhook, so an event-only gate
could never observe a contributor complying that way. The sweeper also
closes drafts from outside the org after 30 days.
The shared check lives in .github/scripts/issue-gate.js so both workflows
run identical logic, with a dependency-free self-check wired into static
analysis. Its one regression guard: author_association CONTRIBUTOR stays
gated, since GitHub assigns it to anyone who has previously committed.
