 - **N105 — Service worker has no `notificationclick` handler** — notification clicks are broken when the tab is closed. Needs `showNotification()` via the SW + a `notificationclick` listener.
 - **N107 — SW has no `push` handler** — Web Push delivery is entirely non-functional. Needs a `push` listener + a Matrix push-gateway integration.
-- **N108 — No maskable PWA icon** — Android adaptive icons render incorrectly. Needs a maskable icon asset + `purpose: "maskable"` manifest entry.
 - **No app-asset caching strategy** (`src/sw.ts`) — no offline capability.
 - **`manifest: false`** in `vite.config.js` — may block correct PWA install if not handled externally.
