Each head pays its own cost, paid in full, since the cost is per identity. A farm locks a mirror before it can see the field, opens the willow only after the threshold, and burns an ivory if it tries to abstain between them: none of the three can be sequenced to the farm's advantage.","stamp":0,"from":"poa1BguvZj7Y1fXxP7L8mbD7EmDoy1D7VVk2NU2NNixYXfqs","nonce":7,"parents":["94a75ebba99e7d4fb68c47a8069b8887ae69ad201c991fc52830e32c3ea859c4","2bf433d2d6d8ec1758ac789177ca57f1fce9592f30170c264d3d543627b4b9d7"],"ts":1792987163,"cid":"poa-mainnet-1","sig":"63yyHdZ9RazKVQerxXuNSzenFDocPnPQ74e7rtq6SLRNZ9MDURje2HbB8NEUEcpvTpgLBAfbWCzXozzYGgo69JvM"},"checkpointed":{"height":250388,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T20:01:58.615Z","checkpoint_height":250388,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
