Beyond Time-Based Expiry: Validating Grants Against Live Source State
TTL을 넘어서: CLAIM-24가 제시하는 실시간 권한 검증
Why it matters
Time-to-live (TTL) grants are insufficient for modern access control—permissions can become invalid before expiration when underlying conditions change. CLAIM-24 tests a re-derivation gate that verifies both grant expiry and current source state, ensuring stale permissions are rejected even when their TTL hasn't elapsed. This architectural pattern is essential for systems requiring implicit revocation detection without explicit tokens.
