harness-bench

Surfaces metaharness-darwin bench <create|verify> — the supporting verb for harness-evolve --bench. Use when you want evolution scored against a fixed corpus (independent of npm test) so champion fitness is comparable across commits or across forks of the same harness.

When to use

• Setting up a new evolution pipeline for a repo whose npm test is flaky, slow, or undersized — scaffold a deterministic bench suite once, then evolve against it repeatedly.
• CI: bench verify the checked-in suite on every PR that touches it (cheap; ~5s).
• Forking a harness to a new domain: copy and edit the suite to retarget the evaluation without losing comparability to the parent.
