Where Zetrix fits the x401 abstractions

x401 abstraction	Zetrix realization
Issuer identity	BID-method DID on Zetrix; issuer public keys resolvable from the DID document
Credential	ZID Verifiable Credential (national ID, business registration, accreditation, membership)
Credential format	sd-jwt (selective disclosure) or jwt_vc_json; mso_mdoc for mDL interop
Revocation / status	On-chain status-list contract; verifiers read status offline via cached snapshots
Trust anchoring	On-chain issuer registry contract; deterministic, tamper-evident, no central CA
Agent binding	Agent key registered as a scoped, revocable delegate under the Principal's DID
