# Domain 11 — Notifications

### `notifications` [CORE]
|
|
**Role:** In-app notifications (no push at launch); `data_json` carries a typed payload for front-end navigation. **Why polled, not pushed:** push is out of MVP scope; a retention job hard-deletes read notifications older than 90 days to bound growth. Fields unchanged. **Relations:** N:1 → `users`.

|
### `support_alerts` [CORE]
|
|
**Role:** Internal-only alerts (low ratings, EVV no-shows, expired verification steps, EVV location mismatch, payment anomalies), with an owner and resolution trail. **Why distinct from notifications:** these are staff worklist items, never shown to users. Fields unchanged. **Relations:** polymorphic (`entity_type`,`entity_id`) — validated at the application layer; consider nullable typed FKs (`booking_id`,`review_id`) for the common cases.
