What this plugin does

Meta-Harness-YGN is a Claude Code plugin (namespace /mh) that brings scientific rigor to harness engineering: every proposed change produces a falsifiable hypothesis, a reproducible evaluation against a 9-check suite, and a recorded entry on a multi-objective Pareto frontier — so you always know whether your harness actually improved, regressed, or just changed.
