 # Business Review
 
-Check actors, workflows, domain concepts, invariants, edge cases, and acceptance criteria.
+Use when reviewing whether a change supports the stated business goal and real user workflows.
 
-Separate stated requirements, evidence, and assumptions. Do not invent business requirements.
+## Review
+
+1. Identify the intended actors, goals, and acceptance criteria from the request or product evidence.
+2. Trace the affected workflow across its relevant states, permissions, handoffs, and failure paths.
+3. Check domain terms, invariants, eligibility rules, and calculations against existing behavior and authoritative product definitions.
+4. Look for unmet acceptance criteria, inconsistent outcomes between related workflows, and impacts on existing users or data.
+5. Separate stated requirements, observed behavior, assumptions, and recommendations. Ask about material ambiguity rather than inventing business policy.
+
+Report actionable gaps with the affected actor and workflow, evidence, impact, and the requirement or decision needed to resolve them. Do not substitute implementation preference for business intent.
