Credential criteria
A credential is issued only from an approved program assertion. For the FDE track, the assertion must
show that the applicable time gate and mastery gate are both met and that required human review is
complete. Program owners approve criteria; the credential service does not invent them.
Evidence and privacy
Credentials contain the minimum claims needed to describe the achievement. Confidential learner,
reviewer, or partner artifacts must remain in access-controlled systems. Public evidence links require
permission and must not expose protected records.
Verification and status
Verifiers should resolve the issuer DID, validate the Data Integrity proof, confirm the achievement
criteria, and check the referenced Bitstring Status List. A successful signature check does not by
itself establish that a credential is current or suitable for a particular decision.
Correction, revocation, and appeal
Holders may request correction of an issuer error or appeal an operational decision by contacting
credential operations. Revocation is used when the credential should no longer be accepted. The
program owner records the reason and approval in the private audit trail; the public list reveals only
status.
Expiration and renewal
A credential is non-expiring unless its published terms include an expiration or renewal requirement.
Specialization and continuing-education credentials may require renewal. The achievement definition
and issued credential control; marketing copy does not change those terms.
Key rotation
New signing keys receive a new verification-method identifier. Prior public keys remain resolvable for
credentials issued with them. A compromised key triggers the incident and rotation runbook; key
replacement must not silently overwrite the identity of existing credentials.
