### Changed

- `labels` — the reconcile cron relaxes from `*/15` to hourly (#199), cutting a
  private consumer's schedule-triggered full-board sweeps ~4× at GitHub's
  1-minute billing floor.
- `labels` — the hourly cron is the sweep's only wake for transitions no
  subscribed event carries — a verdict landing, blocker:ci-red, a
  blocker:conflict when another PR merges, the time-based stale/reclaim — so it
  bounds their latency to ≤1h, delaying no event-carried transition (#199).
- `labels` — the caller's `issues:` trigger narrows to
  `[opened, closed, edited, reopened]` (#199), the actions that carry a
  queue-state change the cron cannot wait a cadence for. The churn/validation
  actions — labeled/unlabeled/assigned/unassigned — come off; the PR handoff
  wake is unaffected.
- `labels` — each caller trigger now carries a comment saying why it is
  subscribed, and reconcile keeps `cancel-in-progress: false` (#199) —
  cancelling a sweep mid-board is the race that guard exists to prevent.
