+## Current Focus to reach ~80%
+
+1. Complete security/privacy UX (sessions revoke behavior, TOTP QR flow, privacy matrix).
+2. Finish channel/group moderation parity (ban permissions, member action polish).
+3. Finalize media messaging UX parity (voice/circle controls, unified attachment behaviors).
+4. Keep realtime strict consistency for all mutations (already improved for edit/delete).
+5. Raise test coverage for auth/chats/messages/realtime critical paths.
