- Voice messages: MediaRecorder → encrypted attachment, custom waveform
player via OfflineAudioContext, 60s limit + live mic-level meter
- Offline message queue: localStorage outbox, exponential backoff retries,
optimistic pending bubble with retry/discard
- Delivery indicator: message_deliveries table + RLS (reciprocal receipts),
✓ / ✓✓ / ✓✓-blue tick states, group-aware (all members must ack)
- Per-participant volume slider in calls via right-click tile menu,
persisted to localStorage, applied to attached audio elements
- Group call scaling: grid up to 12 tiles with pagination,
active-speaker auto-promotion in fullscreen
- Push notifications scaffolding: service worker, VAPID subscription
registration, notify-push edge function skeleton
- Backup recovery code: 24-char base32 code (~120 bits entropy) as
alternative decrypt path, restore UI with mode toggle
- Admin panel: conversations list, audit log (admin_audit_log table +
admin_log_action RPC), audit entry on user flag toggle
- Search v2: sender filter, attachment-only toggle, date range
- Reactions pop animation (scale 0.4→1.15→1 on count change)
- Message list windowing (150 default, expand via IntersectionObserver)
- Stub cleanup: removed dead ScreenshareStub from CallParticipantTile
Fixes:
- Focus-triggered flicker: dropped window.focus listeners in three spots,
throttled visibilitychange/online wake-refreshes to 30s, keep existing
data visible during background re-syncs (no more spinner on every click)
- Voice attachment audio element collapsed to 0px on peer side — now
forces 280px min-width on bubble
