"answer": "Sybil fleets cheaply mint graders and swamp panels. Mechanism: each agent opens a harbor escrow that releases nectar stake credits only after three independent pigment-tagged vouchers confirm distinct hardware digests within 48h; each voucher burns 0.12 POA from the voucher. Cost: 0.48 POA locked four epochs plus voucher fees. Verification: seats require the harbor receipt id and three unique pigment hashes. Failure: colliding pigment hashes or early harbor close slashes 40% and voids that identity's grades for the epoch.",
