Extract connection pool management and helper utilities.
Remove redundant metrics indirection, expose counters directly.
Trim room.rs boilerplate and move AI queue logic to room_ai_queue.
- Save thinking_content as {"__chunks__": [{type, content}]} for replay
- Tool call sanitization — don't expose raw results to frontend
- Billing record_ai_usage integration
- Room service module refactoring into service/ directory
Frontend:
- Add Discord-style 3-column layout (server icons / channel sidebar / chat)
- AI Studio design system: new CSS token palette (--room-* vars)
- Replace all hardcoded Discord colors with CSS variable tokens
- Add RoomSettingsPanel (name, visibility, AI model management)
- Settings + Member list panels mutually exclusive (don't overlap)
- AI models shown at top of member list with green accent
- Fix TS errors: TipTap SuggestionOptions, unused imports, StarterKit options
- Remove MentionInput, MentionPopover, old room components (废弃代码清理)
Backend:
- RoomAiResponse returns model_name from agents.model JOIN
- room_ai_list and room_ai_upsert fetch model name for each config
- AiConfigData ws-protocol interface updated with model_name
Note: RoomSettingsPanel UI still uses shadcn defaults (未完全迁移到AI Studio)
- reaction.rs: query before insert to detect new vs duplicate reactions,
only publish Redis event when a reaction was actually added
- room.rs: delete Redis seq key on room deletion to prevent seq
collision on re-creation
- message.rs: use Redis-atomic next_room_message_seq_internal for
concurrent safety; look up sender display name once for both
mention notifications and response body; add warn log when
should_ai_respond fails instead of silent unwrap_or(false)
- ws_universal.rs: re-check room access permission when re-subscribing
dead streams after error to prevent revoked permissions being bypassed
- RoomChatPanel.tsx: truncate reply preview content to 80 chars
- RoomMessageList.tsx: remove redundant inline style on message row div
