Evaluation evidence / longitudinal comparison · stable v0.2.1

Compare agent attempts with evidence that lasts.

YYLO Benchmark prepares reviewed cases, delegates independent task or workflow attempts, and evaluates retained outputs with new checks and judges. Results remain separate, without an automatic winner.

Published runner, explicit evidence limits

The thin runner uses trusted-host workspace/context hygiene, not enforced filesystem/account/network isolation. Retained prompts do not prove literal provider-message delivery. Workflow prefixes include upstream effects and stop at the selected step.

How this layer strengthens the System of Work.

Benchmark evidence is designed to help teams learn which agent and workflow works best for a repository and change type. Automatic production workflow selection requires connected real-world outcome history and is not a current-release claim.
