+Budget, commitment, spend attribution and planning-evidence consumption.

+## Reuse boundary

+No verified concurrent runtime EUR risk/cost enforcement for agents.

+## Supported use cases
+
+- U09: Maintainer observes posture, prioritizes findings, coordinates work and verifies outcomes
+- U11: Agent executes an attributable bounded task and supplies supervision evidence
+
+## Evidence and integration
+
+- [SCOPE.md](../../SCOPE.md)
+
+Assessment: CUST-WP-0081, 2026-10-14. Relations identify interfaces to compose; they do not certify native integration. Existing external evidence levels are retained where present. New entries use conservative C1/R0 until consumer assessment exists.
