## AI Chat Fixes
- **CRITICAL**: Fixed AI chat responding only with sleep-related info
- Root cause: Current user message was never added to context before sending to AI
- Added user message to context in ai.service.ts before API call
- Fixed conversation ID handling for new conversations (undefined check)
- Fixed children query to properly use FamilyMember join instead of incorrect familyId lookup
- Added FamilyMember entity to AI module imports
- **Context improvements**:
- New conversations now use empty history array (not the current message)
- Properly query user's children across all their families via family membership
## Children Authorization Fix
- **CRITICAL SECURITY**: Fixed authorization bug where all users could see all children
- Root cause: Controllers used `user.sub` but JWT strategy returns `user.userId`
- Changed all children controller methods to use `user.userId` instead of `user.sub`
- Added comprehensive logging to track userId and returned children
- Backend now correctly filters children by family membership
## WebSocket Authentication
- **Enhanced error handling** in families gateway
- Better error messages for connection failures
- Added debug logging for token validation
- More descriptive error emissions to client
- Added userId fallback (checks both payload.userId and payload.sub)
## User Experience
- **Auto-clear cache on logout**:
- Logout now clears localStorage and sessionStorage
- Prevents stale cached data from persisting across sessions
- Users get fresh data on every login without manual cache clearing
## Testing
- Backend correctly returns only user's own children (verified in logs)
- AI chat now responds to all types of questions, not just sleep-related
- WebSocket authentication provides clearer error feedback
