End-to-end data flow verification traces changes from DB through backend services and routes to frontend UI components, confirming type alignment, null handling, and error propagation to ensure correctness and prevent regressions.
Code correctness verification confirms that data flows reach the UI as intended and match API contracts, whereas quality review evaluates broader code structure and standards.
To check field propagation, trace the data flow from the database through the API client and hook or store to the UI component, validating type alignment and null handling at each layer.
You need task descriptions, access to the relevant code paths, and consistent API contracts to perform end-to-end task-based code verification across the backend and frontend stack.
A PASS_NEEDS_E2E outcome indicates data flow logic is correct but requires runtime confirmation, while a FAIL outcome identifies breaks in type alignment, null handling, or error propagation.
