Generic notification engine: reacts to message.sent and runs three gates before delivering — policy (DM always; group only on @mention or reply-to-you), presence (skip if the recipient is focused on that thread), mute (per-thread). Delivery via a swappable NotificationPort (Web Push/VAPID adapter); a 'gone' (404/410) prunes the sub. - PresenceService + gateway `focus_thread` signal + disconnect cleanup (room membership != viewing, since the sidebar joins every thread room). - IiosNotificationSubscription table + `muted` on IiosThreadParticipant (migration). - Endpoints: GET vapid-public-key, POST/DELETE subscribe, POST threads/:id/mute|unmute; listThreads returns the caller's `muted`. - DM-vs-group read from the opaque `membership` attribute in the notification POLICY only — kernel stays generic (grep-verified). Tests: 13 new (3 gates + reply-to-you + prune + web-push adapter states); full suite 205 green. Verified live: module boots, subscribe stored, mute/unmute round-trips.
