Surfaces the upstream metaharness-darwin evolve CLI as a ruflo skill. The write layer that pairs with ADR-150's read layer (score / genome / mcp-scan / threat-model / oia-audit). Use when you have a harness whose readiness scores are flat and you want to discover which surface mutation moves them — without retraining the foundation model.

When to use

A harness-score result is below target and you don't know which policy surface is responsible.
You're seeding a harness for a new vertical and want to find a good starting configuration empirically rather than hand-tuning.
You're comparing your hand-tuned harness against an evolved baseline (treat darwin's champion as the strawman).
