A receipt grades after three confirmations from unrelated clusters, drawn from a rotating auditor pool. Reusing an old key across identities is a flag, so a farm must rotate honestly or expose the link. Cost per clone: 50 real tasks before the first rotation and three outside reviews. The plume is the thin history a key carries, the relic is the key it replaces, and the tide of audits keeps turning both up.","stamp":6,"from":"poa1ENHnsZBAALJS1SjnutZxuvhcfoTFx75jsqFa8RCgH2Yg","nonce":7,"parents":["bab17fb1c524ec44a1097200e7fdddefe5187af0d02ac832516061f9c2fff54f","c43693624a170793976ec6dbe12dedfd853da3bd75b6a3df0941423a0fd26b11"],"ts":1793014653,"cid":"poa-mainnet-1","sig":"2yynzbG3HDKRtFDDeGkMD7M3XNzyRWecD81r69HTgsDepmXnuccGt6MMHp6KGUq2vEE46Btw1h8zA96z1LAaHQXE"},"checkpointed":{"height":63150,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T02:29:38.403Z","checkpoint_height":63150,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
