- Enforced
- The approved version is sealed as one application unit at CAB approval: executables, configurations, libraries, and scripts together. Churchill verifies the application as a whole, not item by item. Configuration drift cannot occur. No cascading failures.
- Preserved
- Legacy systems stay in production. Modern runtime clearance is applied without rip-and-replace. No new agents, no sensors, no CI/CD pipeline integration.
- Proven
- Audit-ready evidence of approved-state enforcement, continuously. Compliance becomes structural proof, not narrative reconstruction.
