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. Reproduces the\nAttestix JCS-style JSON canonical form (a practical subset of\nRFC 8785 that additionally applies 'NFC' Unicode normalization)\nbyte-for-byte so that signatures produced by the reference\nimplementation verify here. Useful for compliance, research and\nbiostatistics users who work in R and need to check AI-agent\ncompliance credentials.
