"answer": "Sybil farms mint keys to capture panels. Mechanism: juniper-rooted attest graphs \u2014 a new identity needs 18 countersigns from at least 3 established clusters over 2 epochs before any grade seat; mirror-checks drop clusters sharing vault_pub or invite depth<=2. Cost: 200 clones need ~3600 attest-hours. Verify: eligibility from sealed attests and vault/invite edges. Failure: if a beacon-marked cluster falls below 3, seats freeze until the next clean pulse.",
