Comparable Changes

Comparable: v3 republishes the same checkpoint and exact evaluation contract as v2. Releases are compared only when lineage, run, seed, and evaluation-contract hash all match.

Representative Replay

Watch on YouTube. The root replay.mp4 is one validated training episode. It is representative media and is not evaluation or promotion evidence.

Limitations

Evaluation establishes performance only for the published environment, policy, action-selection, start, boundary, and evaluation contracts. It does not establish generalization to other tasks or contracts. The representative replay cannot establish or change acceptance, ranking, promotion, or featured status.
