Drift detection mechanisms SHALL be tested through deliberate injection of known drift patterns.

Compliance is evaluated through automated test suites that exercise the control under structured test conditions. Results are deterministically reproducible.

This is a conditional control. Non-compliance with this ACR may result in conditional certification with a mandated remediation period. The Authorized Verification Body will specify the remediation timeline and required evidence for the condition to be cleared. If remediation is not completed within the specified period, the conditional certification will be revoked.
