incidents + incident_updates + maintenance_windows + status_pages tables. Monitor transitions auto-open incidents on down and auto-resolve on recovery; an active maintenance window covering the monitor suppresses alerts and auto-incidents, and status pages report the covered monitor as `maintenance`. Public status view: GET /api/status-pages/:slug/public aggregates overall state, monitor uptime, systems, open incidents, and scheduled maintenance; rendered read-only at /status/:slug. GET /api/badge/:kind/:id.svg serves stateless shields; GET /api/metrics exposes Prometheus text over existing tables; POST /api/import/csv?kind=monitors|domains does header-driven bulk import; /api/export v2 folds monitors/domains/systems rows into the backup payload. Frontend: /incidents with timeline + status flow, /status admin for pages + windows, /status/:slug public page; nav and palette wired.
