Defensibility Element 3 (DE-3): Evidence Register Architecture (GOV-13)
Definition
DE-3 ensures that for every AI capability and every Risk Taxonomy 2026 class, the function maintains contemporaneous proof of control effectiveness and operational behaviour. For each risk-class × capability intersection, the Evidence Register records:
- What evidence exists (artefact description and location)
- Who holds it (accountable owner and system of record)
- When it was last verified (timestamp, verifier, method)
