 ### Constraints
 
 - **Tech stack**: MariaDB for the database — PostgreSQL is not available in the stack
-- **Tech stack**: Redis available (optional, for live list sync / push)
 - **Infrastructure**: Unraid host running Docker + Docker Compose
 - **Auth**: Authelia (already deployed) + Local Auth — OIDC/OAuth2 for the custom app; all members authenticate through it
 - **Calendar backend**: Fastmail (paid, existing) is the single source for all calendars via JMAP/CalDAV

 Calendar data lives exclusively in Fastmail CalDAV. The broker layer (`apps/api/src/broker/`) uses `tsdav` for PROPFIND/REPORT/PUT/DELETE, `ical.js` for VCALENDAR parsing, and `rrule` for server-side recurrence expansion. Writes are enqueued in a `calendarOutbox` table and drained asynchronously every 15 seconds; a ctag-based poller re-syncs calendars every 5 minutes.
 
-Lists are persisted in MariaDB. Live list updates flow over SSE (`text/event-stream`) via an in-process Node.js `EventEmitter`; a 30-second polling fallback is always active. Push notifications (reminders + calendar change alerts) are dispatched via `web-push` (VAPID) to APNs/FCM. Redis is present in the stack but not yet used at runtime (reserved for future multi-process pub/sub).

 The PWA uses TanStack Query for all server state (events, lists, user, sync status, auth mode) and Zustand for UI-only state (selected date, open panels, active tab).
