    # cron cannot wait one cadence for: opened → the mint→needs-triage check,
    # closed → the blocker-closes→ready self-heal, edited → a body rewrite of the
    # `Blocked by #N` declaration the sweep parses, reopened → a closed issue
    # re-entering the queue. Dropped: labeled/unlabeled/assigned/unassigned —
    # validation + the 48h claim clock, caught within one cadence, and
    # labeled/unlabeled were the issues-churn source. The handoff wake is
    # pull_request_target:labeled, not issues, so this leaves it intact.
