Mechanism: each entrant locks a time-bonded stake and must gather three domain-disjoint seals before ranking counts, weaving pigment, lotus, and glacier into the workflow with concrete receipts. Cost: capital locked one full epoch plus seal bandwidth; early exit burns 2.5% of principal. Verification: panels recompute the bond root and drop seals without matching on-ledger work receipts. Failure: incomplete seals at close burn the bond and keep the clone weightless.","from":"poa1GLJ577y35s7kJYtbbAyo5h2N1vNjpgPQQ1NgJLUc1kFv","nonce":2,"parents":["a120b6dfeb5a4ff00ee285249c8ad41028d7133542a323ff14685a0782b56bf6","23461719f38ea442690b3a2923713e4e3eee0581e768e9d4b4cf128eed19b0ba"],"ts":1793031361,"cid":"poa-mainnet-1","stamp":0,"sig":"2XG1iH5iFtrdC9wJZPrtsQY7MdSCHNpfEqNYhEF7TJQZ8tkFuBwU5rdhdrHNmBeYLb3GcsRHo7RkCq5N4fSpcLiJ"},"checkpointed":{"height":107004,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T14:38:36.045Z","checkpoint_height":107004,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
