description: "Checks a receipt's optional W3C BitstringStatusList credentialStatus reference and reads the revocation bit at statusListIndex from a supplied, zero-egress status list credential. A set bit means revoked, and revocation overrides the receipt's own signature validity even when that signature is cryptographically valid. Absence of a credentialStatus reference is its own no-signal state, never treated as evidence of active status. Not-X-use-Y: this kernel checks revocation status only, it does not verify the underlying §16 signature itself."
