+Touching security, persistence, concurrency, retry, or public-contract code is not by itself a stop
+condition. Implement routine fixes within existing approved contracts and invariants, with focused
+validation for the affected risk. Escalate before choosing or changing a material invariant, ownership
+model, architecture, security/privacy or authorization policy, migration strategy, public contract,
