Methodology

Canonical methodology noteThis definition

Python execution/checking is evaluator-provided; the model task is reasoning about execution, not requiring a runtime.

Evaluation environment

What the benchmark's harness provides and allows. These are properties of the environment, not model requirements, and applicability does not test for them.

Interaction

None. Static prompts and answers.
