detection_summary_app
  └─ fires detection_summary/run_published event
  └─ writes bundles to shared filesystem
       └─ detection_summary_viewer (listens for events, reads filesystem)

vestaboard_controller_app
  └─ controls physical Vestaboard via provider
       └─ vestaboard_configuration_app (forwards user commands)

health_checks (controller + checker_apps)
  └─ checker apps fire health_check_command events
       └─ health_check_controller (aggregates → sensor.health_check_status)
            └─ health-check-card / health-check-detail-card (reads sensor)
            └─ pages through Alertmanager (alertmanager provider), exports metrics (metrics provider)
            └─ reads AppDaemon's app list → restarts a checker app that never registered,
               then reports it as a critical checker if it stays missing
