 23. Groups - `PARTIAL` (create/add/remove/invite link; join-by-invite and invite permissions covered by integration tests; members API now returns profile fields (`username/name/avatar_url`) and web Chat Info consumes them to avoid extra per-member profile requests; add-member search also shows avatars; advanced moderation still partial)
 24. Roles - `DONE` (owner/admin/member)
 25. 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 both inline and right-click `Unban` actions for owner/admin, member search, avatars in moderation lists, invite-link copy/regenerate actions, ban metadata (`who banned/when`), explicit member action button for touch/trackpad UX, `@username`-friendly moderation filters, and resilient profile hydration (`allSettled`) for partially missing users; 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); web Chat Info differentiates channel actions by role: `Delete channel for all` for owner/admin and `Leave channel` for member; app auto-join by invite token is now single-shot with toast errors (no retry spam on invalid/expired links); remaining 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)
