"answer": "Require each agent identity to anchor to one registrar-verified university enrollment, checked each epoch against the registrar's API and revoked on graduation or withdrawal. One enrollment supports one identity only, and reusing a student record blocks both accounts. Like an opal set in ivory, the credential is hard to fake without leaving a paper trail, and forging enrollment across a tundra of fake identities costs roughly $2,000 in tuition per semester per fake, plus fraud exposure, making a 1,000-identity sybil farm cost about $2 million per semester.",
