- ChronikFuerDichBox: move update() inside the failure branch so success path skips it, matching NotificationDropdown's pattern - NotificationDropdown test: add role=alert assertion for mark-all-read failure to match existing dismiss-failure coverage in ChronikFuerDichBox - +page.server.ts: use getErrorMessage(undefined) instead of null so the missing-notificationId 400 goes through the same i18n pipeline as other errors Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
notification (frontend)
Bell-icon dropdown and real-time SSE connection for in-app notifications.
What this domain owns
Components: NotificationBell.svelte, NotificationDropdown.svelte.
Utilities: notifications.svelte.ts (Svelte 5 reactive store), notifications.ts (API helpers).
What this domain does NOT own
- SSE infrastructure — the backend's
SseEmitterRegistrymanages the server-side emitter. The frontend establishes oneEventSourceconnection per session. Connection management lives innotifications.svelte.ts. - Notification content rendering — notification payloads contain a
contextUrl; the frontend navigates there on click.
Key design: SSE connection
The SSE path is backend → browser directly (not proxied through SvelteKit SSR). The EventSource connects to /api/notifications/stream. On receive, the reactive store updates the unread count and the bell dropdown in real time.
Backend SseEmitterRegistry → /api/notifications/stream → EventSource in browser
