 ## Phase 3: Comprehensive Control Endpoints (POST)
-- [ ] Task: Implement worker and pipeline control.
-    - [ ] Add `/api/mma/workers/spawn` to manually initiate sub-agent execution via the API.
-    - [ ] Add `/api/mma/workers/kill` to programmatically abort running workers.
-    - [ ] Add `/api/mma/pipeline/pause` and `/api/mma/pipeline/resume` to control the global MMA loop.
-- [ ] Task: Implement context and DAG mutation.
-    - [ ] Add `/api/context/inject` to allow programmatic context injection (files/skeletons).
-    - [ ] Add `/api/mma/dag/mutate` to allow modifying task dependencies through the API.
-- [ ] Task: Update `api_hook_client.py` with corresponding methods for all new POST endpoints.
-- [ ] Task: Write integration tests for all new control endpoints using `live_gui`.
