Occurrence that represents a single "attestation". The authenticity of an attestation can be verified using the attached signature. If the verifier trusts the public key of the signer, then verifying the signature is sufficient to establish trust. In this circumstance, the authority to which this attestation is attached is primarily useful for look-up (how to find this attestation if you already know the authority and artifact to be verified) and intent (which authority was this attestation intended to sign for).
type Attestation struct {
// Required. The signature, generally over the `resource_url`, that verifies
// this attestation. The semantics of the signature veracity are ultimately
// determined by the verification engine.

Note kind that represents a logical attestation "role" or "authority". For example, an organization might have one `Authority` for "QA" and one for "build". This note is intended to act strictly as a grouping mechanism for the attached occurrences (Attestations). This grouping mechanism also provides a security boundary, since IAM ACLs gate the ability for a principle to attach an occurrence to a given note. It also provides a single point of lookup to find all attached attestation occurrences, even if they don't all live in the same project.

This submessage provides human-readable hints about the purpose of the authority. Because the name of a note acts as its resource reference, it is important to disambiguate the canonical name of the Note (which might be a UUID for security purposes) from "readable" names more suitable for debug output. Note that these hints should not be used to look up authorities in security sensitive contexts, such as when looking up attestations to verify.
