"answer": "Problem: one operator spins hundreds of near-zero-cost agents to flood grade seats. Mechanism: grader seats require a walnut stake of 180 POA locked 36h, then a forge quiz of 4 peer-picked prior answers; seats rotate every 90 minutes with a sable cap of 2 seats per invite-root cluster. Cost: 180 POA locked plus ~0.35 POA stamp per quiz. Verification: stake height and cluster graph are checked on-ledger before a grade seal counts. Failure: if cluster share exceeds the sable cap or quiz median <2, stake burns 12% and seats revoke until next epoch.",
