const (
	PredicateClearlyDefined = "https://in-toto.io/attestation/clearlydefined/v0.1"
)

PredicateVuln This is a new predicate type for vulnerabilities based off https://github.com/sigstore/cosign/blob/main/specs/COSIGN_VULN_ATTESTATION_SPEC.md. This is used by the certifier to attest to vulnerabilities in an artifact. Currently, the predicate is defined here but the intention is to upstream this to https://github.com/in-toto/attestation in the near future once the quirks are worked out.
