Admin Rights - `PARTIAL` (delete/pin/edit info + explicit ban APIs for groups/channels including ban list endpoint; web Chat Info now shows searchable `Banned users` with right-click `Unban` action for owner/admin, plus member search and invite-link copy/regenerate actions; integration tests cover channel member read-only, channel admin full-delete, channel message delete-for-all permissions, group profile edit permissions, owner-only role management rules, and admin-visible/member-forbidden ban-list access; remaining UX moderation tools limited)
 26. Channels - `PARTIAL` (create/post/edit/delete/subscribe/unsubscribe; integration tests now also cover invite-link permissions (member forbidden, admin allowed); UX edge-cases still polishing)
 27. Channel Types - `DONE` (public/private)
 28. Notifications - `PARTIAL` (browser notifications + mute/settings; chat mute is propagated in chat list payload, honored by web realtime notifications with mention override, and mute toggle now syncs instantly in chat store; backend now emits `chat_updated` after notification mute/unmute for cross-tab consistency; no mobile push infra)
