Prism Arena

Every contender receives the byte-identical task prompt through the identical command, with tools, skills, and rules disabled as a fairness control.

A label-blinded four-judge panel scores the first valid recorded run for each model and task pair, and the results report per-run validity next to the more flattering best-of-two figure.
