It approves only when evidence carries its quality dimensions, is hashed with a trusted timestamp, is redacted/tokenized where needed, and is sealed to an approved destination with retention/legal-hold applied; it blocks approving or executing an action, asserting control effectiveness or framework satisfaction from sealed evidence, or sealing an unredacted secret or personal field.",
