 Focus: Move `app_instance` and `mock_app` to `tests/conftest.py` and remove them from individual test files.
 
 - [x] Task 1.1: Add `app_instance` and `mock_app` fixtures to `tests/conftest.py`. Ensure they properly yield the App instance and tear down. [35822aa]
-- [ ] Task 1.2: Remove local `app_instance` and `mock_app` fixtures from all 13 identified test files. (Tier 3 Worker string replacement / rewrite).
+- [~] Task 1.2: Remove local `app_instance` and `mock_app` fixtures from all 13 identified test files. (Tier 3 Worker string replacement / rewrite).
 - [ ] Task 1.3: Delete `tests/test_ast_parser_curated.py` if its contents are fully duplicated in `test_ast_parser.py`, or merge any missing tests.
 - [ ] Task 1.4: Run the test suite (`pytest`) to ensure no fixture resolution errors.
