Case scope

Turns implicit context into an explicit cause 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

Sample boundary fixture

This sample comes from the broken implementation of a controlled reproducer.

Boundary fixture	Actual	Expected	Outcome
implicit context	`["RuntimeError", "ValueError", "ValueError", true]`	`["RuntimeError", null, "ValueError", false]`	Failed
