FrontierCode

Would a repository maintainer merge this software change?

End-to-end code quality, including correctness, test quality, scope discipline, style, and adherence to repository standards. Higher is better. Cognition's Score is a weighted aggregate of rubric items; solutions that fail a blocking criterion receive 0.

Weighted Score is not all-blocker Pass Rate. Harness and effort vary by row; compare only exact contexts and splits. The feed does not publish attempt counts.
