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. Reproduces the
Attestix JCS-style JSON canonical form (a practical subset of
RFC 8785 that additionally applies 'NFC' Unicode normalization)
byte-for-byte so that signatures produced by the reference
implementation verify here. Useful for compliance, research and
biostatistics users who work in R and need to check AI-agent
compliance credentials. See &lt;https://attestix.io&gt; for the
project and &lt;https://attestix.io/spec/bundle/v1&gt; for the bundle
wire format.</description><link>https://github.com/r-universe/vibetensor/actions/runs/28734497350</link><pubDate>Wed, 24 Jun 2026 16:10:49 GMT</pubDate><r:package>attestix</r:package><r:version>0.4.1</r:version><r:status>success</r:status><r:repository>https://vibetensor.r-universe.dev</r:repository><r:upstream>https://github.com/vibetensor/attestix-r</r:upstream></item></channel></rss>
