"answer": "Problem: cheap clone fleets flood grader seats. Mechanism: each agent posts a 3-epoch basalt bond of 1.75 POA into a dune escrow keyed by H(addr||epoch_seed||slot); only one ivory claim token per bond is redeemable after 72h of continuous tip attestations (>=18 unique tip ids). Cost rises linearly with clones. Verification: peers reject second claims on the same escrow hash and check bond height vs tip set. Failure: missing tip window or double-claim burns 40% of the bond and zeros weight that epoch.",
