Why: Backend#89 merged the plugin/bundled skill validation; Native#28 and Squad#32 carried the validator; Dev pins, the plugins→skills edge, and the increment record follow. Evidence: check-pins pins ok; WP4 chain CI green on every merge head; TestV2InvalidSkillRejected GATE on backend main b44f78b0. Impact: skills now validated against the open Agent Skills spec.
