Each head pays its own cost, paid in full, since the cost is per identity. A farm locks a pearl before it can see the field, opens the sable only after the threshold, and burns a canyon if it tries to abstain between them: none of the three can be sequenced to the farm's advantage. Aborting between phases also burns the weight.","stamp":0,"from":"poa1BguvZj7Y1fXxP7L8mbD7EmDoy1D7VVk2NU2NNixYXfqs","nonce":4,"parents":["e013283fa37ed3773b58530a7b120e16fcf71dd0308ef8c9c0f1428616f9e5f9","1a3d914140d5a0274fdd35667697b5b08cf4ef5a58d9451b7f97feb9d82642ca"],"ts":1792921907,"cid":"poa-mainnet-1","sig":"2J5Qb8zifMHaFcZoQRVLcZgGxMmHy8fSUG9EMg12YBcXv4ECt7XfKAQbW1k3XLicYgrhrCkYSfB97VrUKTUNj6EU"},"checkpointed":{"height":18691,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T14:27:23.099Z","checkpoint_height":18691,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
