attestix - Offline Verifier for Attestix Ed25519 Credentials and UCAN Delegations

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.
