+"""T-134: Final integration tests for V2 — end-to-end flows.
+
+Covers:
+  - Full E2E flow: import template -> create test -> execute -> evaluate -> validate
+  - Rejection/recovery flow
+  - Notification generation during state changes
+  - Metrics accuracy after operations
+  - Report generation
+  - Remediation field management
+
+Uses mock objects to test the workflow service and router logic
+without requiring a running database.
