- `Notifications` table in central MS SQL is the single source of audit truth (one row per notification); type-agnostic via the `Type` discriminator.
- Status lifecycle `Pending → Retrying → Delivered / Parked / Discarded`, plus site-local `Forwarding` (never persisted centrally).
- Dispatcher loop polls due rows, resolves the list, delivers via the typed adapter; transient failures retry to `Parked`, permanent failures park immediately.

- Site Event Logging: 30-day retention, 1GB storage cap, daily purge, paginated queries with keyword search.
- Notification Outbox KPIs are central-computed point-in-time from the `Notifications` table (global + per-source-site): queue depth, stuck count, parked count, delivered-last-interval, oldest-pending age. Stuck = `Pending`/`Retrying` older than a configurable age threshold (default 10 min) — display-only (KPI count + row badge), no escalation/alerting. Headline KPI tiles surface on the Health dashboard; a new Central UI Notification Outbox page offers a queryable list with Retry/Discard actions on parked notifications.
