 ## Phase 1: Stream Structure Enhancement
 Focus: Extend existing mma_streams for per-worker tracking
 
-- [ ] Task 1.1: Initialize MMA Environment
-- [ ] Task 1.2: Review existing mma_streams structure
-    - WHERE: `src/app_controller.py` line 142
-    - WHAT: Current is `Dict[str, str]` - stream_id -> accumulated text
-    - NOTE: Keep this structure, add per-worker metadata separately
+- [x] Task 1.1: Initialize MMA Environment (skipped - already in context)
+- [x] Task 1.2: Review existing mma_streams structure - Already exists: Dict[str, str]
 
 ## Phase 2: Worker Status Tracking
 Focus: Track worker status separately
 
-- [ ] Task 2.1: Add worker status dict
-    - WHERE: `src/app_controller.py`
-    - WHAT: Track status per worker
-    - HOW:
-      ```python
-      self._worker_status: dict[str, str] = {}  # stream_id -> "running" | "completed" | "failed" | "killed"
-      ```
-
-- [ ] Task 2.2: Update status on worker events
-    - WHERE: `src/app_controller.py` `_process_pending_gui_tasks()`
-    - WHAT: Update status based on mma events
-    - HOW: On "response" event, set status to "completed"
+- [x] Task 2.1: Add worker status dict - Added _worker_status dict to app_controller.py
+- [x] Task 2.2: Update status on worker events - Status updates to "completed" when streaming ends
 
 ## Phase 3: Multi-Pane Display
 Focus: Display all active streams
