Debugging

Execution Workflow

1. Reproduce the issue with the smallest possible app, route, or test case.
2. Identify the failing layer first: requests, routing, dependency injection, middleware, auth, responses, exception handling, or lifecycle.
3. Turn on only the minimum safe diagnostics needed: local debug=True, focused logs, or temporary assertions.
4. Inspect the boundary where the behavior diverges from expectation.
5. Fix the root cause, remove temporary diagnostics, and add a regression test.
6. Re-run the affected tests and re-check the surrounding contract for regressions.
