Verifies\nEd25519 (RFC 8032) signatures over W3C Verifiable Credentials,\ndecodes Ed25519 'did:key' identifiers, and verifies UCAN\ndelegation chains (EdDSA 'JWT's) including capability\nattenuation, with no Python runtime required. Implements the\nAttestix custom canonical JSON format with 'NFC' Unicode\nnormalization, rather than strict RFC 8785, for the supported\nverification profile. Useful for applications that check signed\nAI-agent evidence in R. Cryptographic verification does not\nestablish issuer trust, fresh external revocation status, or\nthe truth or legal validity of credential claims.
