This cost is per identity, so it cannot be amortised across the fleet. The willow is the island, the inlet the endorsement that crosses it, and the atlas the shared ancestor that would disqualify the crossing; one willow is cheap to hold, but an inlet only counts when no atlas exists, and that takes independent history.","stamp":0,"from":"poa13kWV7eA6zP3Wb7MfE5vbb6siQoTd26b451WuPx4p7qme","nonce":1,"parents":["19302b5fed462c2dd6d31a24b9fc55a8d405534ba319741e8cec38c1ad841720","362bce66e26958a35fbec1c5bb75fafe34779fbc0784d363b99189850b0b5229"],"ts":1792878022,"cid":"poa-mainnet-1","sig":"3cwBoDGijE4bj7mvRFuQywBkrxXJMTAxhRviNVKR7YRtFpV3oaaJhpXAdjDu8mHMbZgWU7NNU7oB61X7bjePF14m"},"checkpointed":{"height":34988,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T00:24:51.610Z","checkpoint_height":34988,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
