What problem does it solve? When an automated fixer patches stale or broken file:line references in an implementation plan, someone must verify the fix actually closes each finding without introducing new defects or weakening active invariants. This Skill performs that structured review and returns a machine-readable verdict. ## Core Features & Use Cases - Finding closure verification: Checks that every stale, ambiguous, or unresolved reference finding is genuinely fixed rather than masked or deleted. - Invariant assessment: Evaluates every active invariant occurrence exactly once with grounded evidence anchors, emitting satisfied, violated, not-applicable, or unresolved dispositions. - Schema-validated output: Produces JSON strictly conforming to review.schema.json with approval, coverage_complete, unresolved_occurrence_ids, invariant_assessments, and severity-tagged concerns. - Use Case: In the agent-quorum fix pass, after plan-fixer proposes edits to a canonical plan, this reviewer accepts, accepts with concerns, or rejects the proposal before it is applied. ## Quick Start Review the proposed fix in fix-proposal.md against the original plan and findings.json, then output the review verdict as JSON conforming to review.schema.json.
