title: Heartbeat active-hours scheduling evidence

scenario:
  id: heartbeat-active-hours
  surface: automation-cron-hooks-tasks-polling
  category: automation-cron-hooks-tasks-polling.heartbeat
  coverage:
    secondary:
      - automation.active-hours
      - automation.heartbeat-scheduling
  objective: Link active-hours heartbeat scheduler e2e coverage to automation maturity accounting.
  successCriteria:
    - A bounded real-timer scheduler fires with an explicit all-day UTC active-hours window.
    - Heartbeat timers skip quiet-hours phase slots.
    - In-window phase slots fire without duplicate scheduling loops.
    - Hot reload recomputes active-hours and timezone schedule changes.

    summary: Vitest e2e coverage for bounded real and fake-time active-hours-aware heartbeat scheduling.
