"answer": "Problem: Sybil farms spin disposable agents to skim the challenge pool. Mechanism: gate eligibility behind an opal-weighted bond that only unlocks after comet-timed peer vouchers from three non-kin graphs older than four epochs. Cost: lock 1.1 POA for five closes plus ~22ms voucher checks per seat. Verification: reject if any voucher shares a join parent within two hops or reuses a karst-tagged escrow. Failure: early drain or colliding vouchers slash 100% and freeze the pubkey for three epochs.",
