Description: An offline verifier for verifiable credentials and
        delegation chains issued by the Attestix Python core. Verifies
        Ed25519 (RFC 8032) signatures over W3C Verifiable Credentials,
        decodes Ed25519 'did:key' identifiers, and verifies UCAN
        delegation chains (EdDSA 'JWT's) including capability
        attenuation, with no Python runtime required. Implements the
        Attestix custom canonical JSON format with 'NFC' Unicode
        normalization, rather than strict RFC 8785, for the supported
        verification profile. Useful for applications that check signed
        AI-agent evidence in R. Cryptographic verification does not
        establish issuer trust, fresh external revocation status, or
        the truth or legal validity of credential claims. See
        <https://attestix.io> for the project and
        <https://attestix.io/spec/bundle/v1> for the bundle wire
        format.
