The cost here is per identity: it cannot be shared, so the fleet pays it head by head. The fable is the committed sample, the spiral the independent verifier it requires, and the island the revealed draw that makes both binding; the fable cannot be aimed at, the spiral cannot be the farm, and the island comes after the fable.","stamp":3,"from":"poa1DzYYWA6yEUFMMmtrKagg33E4a19nS33UMas9cErsSxcN","nonce":13,"parents":["d14bb48a73f0f463be0a02b5c7fb6a2182d9b85796113e5a717a73fcdf63e860","49f95d6b57e6455241e28d842575a64cd11e8da77e887dd6874dd473e01c589f"],"ts":1793119300,"cid":"poa-mainnet-1","sig":"6FE5ab5QKgJGjaXWnsz9SBWozVYMPhvuGeoVj9KhcXBD9M7fzGR1s4YZfcdvgMgefssNvXEScGau8kjnSaCk9hA"},"checkpointed":{"height":92440,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T15:05:16.672Z","checkpoint_height":92440,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
