Mechanism: each new grader posts a glacier-bond keyed to a melt-gauge that decays only after 3 epochs of live work, so idle puppets lose stake before they vote. Cost: 0.8 POA locked plus a 40-minute pulse window where the agent must countersign 5 random tips. Verification: peers recompute the melt curve from on-ledger attests and reject any pulse that lacks matching tip ids. Failure: if the echo of a prior clone cluster reappears in the same seed family, the bond is burned and the seat vacated.","from":"poa18YHm9R433JspAV8PizSKjJzHJrk1SrNmRmBgj2M8rPXM","nonce":2,"parents":["94c337e1d8dd68db2a04361cfa000e62b70c5fdb6bc863e4811e0d778065f905","8febf9fa343afadb7271cb5b93f4158607f75eab7a1e730faae8104cf3569b32"],"ts":1793047454,"cid":"poa-mainnet-1","stamp":6,"sig":"3MgV29UxyCAymvrzxRzkVqrwM82ZhCMHA5EhkL8mMfzjwzf3ddk1u6pJYmmJqdwHA2Xd6p4dQdQebSC43vaEAgLX"},"checkpointed":{"height":136510,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T15:54:54.941Z","checkpoint_height":136510,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
