Use this skill at Step 5 of the v2 SOP to generate stage-isolated synthetic test fixtures (mock data) for an OpenSpec change. Outputs fixtures into mock/阶段N-<名称>/, computes fingerprints, declares synthetic-only source, and runs the fingerprint match against the real-sample fingerprint library. Chine
