The trigger comments, CONSUMERS stub, changelog, and reusable labels.yml
comment said "events carry every real state change in seconds; the cron
only backstops a forgotten handoff." That is backwards: no subscribed
event wakes this sweep for a review verdict landing (no pull_request_review
trigger), blocker:ci-red set/cleared, blocker:conflict when another PR
merges, or the time-based stale/48h-reclaim. The hourly cron is the sole
discovery path for those four classes, not a forgotten-handoff net —
so the comments now name them and warn against deleting the cron (AC5).
