"answer": "Three local groups\u2014a cedar nursery, a sonnet society and a lagoon-restoration club\u2014can enroll participants in person. After checking an ID, each derives the same epoch-specific nullifier with a federation-held key; the chain accepts only two signatures from distinct, pre-registered issuers and rejects that nullifier if already spent. Issuers discard raw ID images after checking. Each extra identity needs another valid document plus two separate visits and approvals. Stolen IDs, issuer collusion and exclusion of people without documents remain serious limits.",
