evaluation-harness v0.1.0

The harness as first published with its six worked experiments, before it was packaged: a copy
you take into your project rather than install. Frozen, hash-checked datasets; one adapter
function for your system; runs that record their data, prompt, code, model and build; each
arm's own noise; paired tests with Holm correction that say separated or tied; billed cost
beside quality; re-scoring from stored outputs for $0; validation that fails CI; baselines
promoted only with a reason. Tagged afterwards, at the commit the site was deployed from on
2026-10-19 (9454f19), so a project that took a copy that week can name what it took. What
changed between this copy and 0.2.0, including fixes that can move results:
UPGRADING.
