Round 1 review (claude-bot, codex-bot on #138 and the sibling PRs).
gh issue edit rejects the WHOLE call on one unknown label name, and this
change made state and blockers share a single edit for anti-flicker. On a repo
whose taxonomy predates the blocker:* labels -- every repo, at merge -- the
first sweep would therefore converge NOTHING on exactly the PRs the change
exists to fix, surfacing only as a warning in a cron log. Adds are now
filtered against the repo's real label set, read once per sweep. Removals need
no filter: they are built from has_label, so they provably exist. An
unreadable label set does not filter, because a failed read must not silently
strip the board.
blocker:unrequested also missed the stale round. MISSING and STALE are both
verdicts this head does not have -- nobody reviewed it, or everybody reviewed
something else -- and the agent owes an ask either way. The stale one is the
worse of the two: it has approvals on the page that no longer describe the
tree, which is the case LABELS.md already called the most dangerous.
Fixtures 66 -> 68.
