Ardyn Sentinel — live system state and fail-closed verification
| Category | Result |
|---|---|
| Service Availability | ✅ 5/5 |
| Auth Boundary | ✅ 2/2 |
| Dependency Failure | ✅ 4/4 |
| Protocol Integrity | ✅ 5/5 |
| Concurrency Integrity | ✅ 4/4 |
Ardyn Sentinel is continuously tested against fault conditions including service crashes, authentication bypass attempts, dependency failures, protocol integrity attacks, and concurrency stress. Every test verifies that the system fails closed — no false Data Destruction Certificates are ever issued under any tested failure condition.
If the sovereignty pipeline fails at any point — before, during, or after inference — the destruction nonce is burned and no result is recoverable. No Data Destruction Certificate is issued for incomplete executions. The monotonic counter preserves integrity across crashes and is protected against rollback by a three-layer verification system.
