 ## Phase 2: Foundational Tasks
 
 *Goal: Establish authentication and infrastructure required for the integration.*
 
-- [ ] T005 Refactor `backend/src/services/auth.py` to implement Strategy pattern (`JWTValidator` and `StaticTokenValidator`)
-- [ ] T006 [P] Create unit tests for new Auth Strategy in `backend/tests/unit/test_auth_strategy.py`
-- [ ] T007 Update `backend/src/api/middleware/auth_middleware.py` to use the new Auth Service strategies
-- [ ] T008 Update `backend/src/api/main.py` to configure CORS for `https://chatgpt.com`

-- [ ] T011 [P] [US1] Create `SearchWidget` component in `frontend/src/components/SearchWidget.tsx` for the widget view
