Case scope
Returns a constant fallback instead of the requested missing attribute name and changes the required Python-language result.
Why this case matters
Runs Python standard-library language operations in a deterministic local reproducer. Literal expected answers are authored independently. Related defects share an evaluation group to avoid benchmark split leakage.
One recorded failure
