Attestations

Verifiable credentials issued against entries.

Attestations are detachable — they don't change the entry. They travel alongside it and are returned in GET /v1/attestations/<did>.

Standard types

  • build-reproducible
  • license-verified
  • no-malware-detected
  • eval-passed
  • human-reviewed
  • dependencies-pinned
  • sbom-attached

Custom types are allowed; reuse a standard type when one fits.

Independence weight

Discovery ranking weighs independent attesters higher than repeated attestations from the same auditor. A single attester signing 100 entries contributes less to ranking than 5 different attesters signing the same entry.
