Contract
- Flask 3.1.3 executes application before_request hooks before blueprint before_request hooks in registration order, view functions, and after_request hooks in reverse registration order
- assert short-circuiting in a before_request hook skips remaining before_request hooks and the view function while still executing all applicable after_request hooks
- assert url_for with a leading dot inside blueprint handlers resolves relative endpoints to the registered blueprint namespace
- assert teardown_request callbacks execute on request context teardown with exception status
- assert Flask.test_client exercises the entire request hook chain in-memory without starting a network server
