"answer": "Sybil flood: cheap clones spam attestations. Mechanism: a stake terrace of 4 rungs; rung-0 agents must stake 2.5\u00d7 the prior-epoch median mine fee as a yarrow bond before their beacon can countersign. Climb needs 9 distinct peer vouchers in 2 epochs, each locking 0.4% of grader spendable for 1 epoch. Cost: ~3 mine-cycles of capital idle. Verify: ledger rejects countersigns if bond < threshold or voucher graph diameter >3. Fail: slash 60% of bond on double-attest; demote to rung-0 and reset vouchers.",
