- Add trajectories API endpoints (list, get, save, delete) with SSE subscription - Implement automatic title generation for chat trajectories via LLM - Refactor chat state to support multiple concurrent threads with per-thread runtime state - Update selectors to access thread-specific state by ID - Add useTrajectoriesSubscription hook for real-time trajectory events - Update test fixtures and mock handlers for trajectory operations - Migrate chat form and story fixtures to new multi-thread state structure
- Add per-thread state tracking (streaming, waiting, confirmation) instead of global
- Implement open_thread_ids array to manage visible tabs vs background runtimes
- Add switchToThread action to switch between open tabs and auto-switch on confirmation
- Update setIsWaitingForResponse to accept {id, value} payload for per-thread control
- Add closeThread force flag to allow deletion of busy threads (e.g., on backend delete)
- Update restoreChat to preserve existing runtimes and re-add to open tabs
- Add auto-switch listener: when background thread needs confirmation, switch to it
- Update updateOpenThread to only sync metadata (title) not messages (avoid stale data)
- Add setThreadPauseReasons to also set streaming=false and confirmationStatus=false
- Update removeChatFromCache to check confirmation.pause before deleting
- Add selectThreadPause selector to check pause state
- Update Toolbar and HistoryItem to show spinner for both streaming and waiting states
- Update ChatForm to check pause state without streaming condition
- Update middleware to set waiting=true before continuing after tool confirmation
- Add error handling in reducer for rejected chatAskQuestionThunk
- Update useCompressChat and useSendChatRequest to use per-thread waiting state
- Update useTrajectoriesSubscription to force-delete on backend delete and sync only metadata
- Update version to 2.0.10-alpha.4
Preserve auto-generated titles in history when saving chats, and allow backend-generated titles to sync even during active streaming. Restrict other field updates to non-busy threads to avoid overwriting user changes.
- Fix abort handling: dispatch doneStreaming immediately on abort to prevent late cleanup from corrupting new requests - Set waiting_for_response=true before async confirmation check to block duplicate senders during the async operation - Re-check state after async operations to prevent stale state issues - Exclude messages from backend updates to keep local runtime authoritative - Remove duplicate tool auto-continue from useAutoSend (now single source of truth in middleware doneStreaming listener)
- Extract constant default values in selectors to prevent unnecessary object creation on each call (EMPTY_MESSAGES, EMPTY_QUEUED, etc.) - Import ChatMessages and thread types for better type safety - Add safety checks for incomplete tool calls after aborted streams - Improve stream consumption abort handling with deduplication flag to prevent multiple onAbort callbacks - Add abort signal checks between chunk processing to stop early on user abort
- Move UsageCounter to AgentCapabilities header and ChatForm - Relocate MessageUsageInfo rendering to ChatContent message flow - Remove LikeButton and SaveTrajectory functionality - Simplify AssistantInput props by removing usage data - Refactor UsageCounter with circular progress visualization - Move ResendButton to ChatForm toolbar - Remove trajectory save endpoint from router - Clean up knowledge API and remove unused SaveTrajectoryResponse - Update story fixtures to remove deprecated handlers - Adjust component imports and dependencies across chat modules
Add logic to automatically close empty chat tabs when: - Creating a new chat via onCreateNewChat - Navigating to a different tab via goToTab This improves UX by preventing accumulation of empty chat tabs in the tab bar. Only tabs with no messages are closed automatically.
