Research direction

Start by reading the linked follow-up issue #7655 to understand the intended behavior and any affected entry points. Then trace how mypy checks async context-manager exit methods and determine what test should cover a false return from a method declared to return bool. Done means the requested diagnostic is produced consistently.
