Validity and Revalidation

Validity windows

Artifacts and claims are valid only within their windows. Expiry invalidates readiness.

Revalidation triggers (normative)

• SB boundary expansion or interface widening
• DR boundary or impact change
• Delegation level change
• Mandate/authority change
• Scope split/merge or precedence change
• Evidence expiration or reachability failure
• Reference MAJOR version adoption

Any trigger in a scope with semi‑autonomous delegation MUST cause DRC reissuance.
