Belt-and-suspenders to the plugin sweep (plugin-legal-ai #3). Comments that
arrive mid-run aren't re-read automatically — an agent reads comments once at
run start (§2), so a chair comment that lands after that point and before the
run closes the issue is never seen. That is exactly how a chair comment on
CMP-190 (2026-06-30) was dropped.
Adds a mandatory gate to HEARTBEAT §4ב: before PATCH status=done, re-read
comments and compare to the run-start list. If a new unaddressed chair comment
exists — do not close. Either handle it (and record a comment) or, if it
widens scope, keep the issue open and hand back to the CEO (§4ג). Never mark
done while a chair comment waits unanswered.
The plugin sweep catches orphaned comments within ~2 min; this gate prevents
the drop at the source. Refs legal-ai #164.
