Audit Drift

Audit state before changing behavior. Find contradictions, drift, and weak state modeling first, then apply the smallest safe fix.

Follow this workflow

1. Inventory every state surface involved in the feature or bug.
2. Mark the source of truth for each state value.
3. Trace how state is written, derived, cached, serialized, and invalidated.
4. Identify impossible combinations, duplicated state, and uncontrolled transitions.
5. Prioritize findings as P1 through P4.
6. Auto-fix only local, low-risk issues. Leave wider schema or contract changes as findings with a concrete fix plan.
