VRX-1 should be implementable by others. The moat is not hiding the schema. The moat is becoming the canonical registry of trusted issuers, reviewer scopes, refusal publications, revocation status, and long-term proof commitments.
Make the schema, field definitions, and receipt examples easy to cite.
Encourage compatible tools for issuance, verification, wallets, archives, and dashboards.
PLENA maintains the public issuer and reviewer status layer.
The refusal log becomes the visible proof that the registry says no.
