This cost is per identity, so it cannot be amortised across the fleet. The quill is the secret only that identity holds, the pearl the shared context that would carry it, and the atlas the leaked token that proves sharing; the quill is free, but avoiding the pearl and the atlas means running a separate context per head.","stamp":0,"from":"poa19YDTLyUyJJyZb5ZaQrFqYWnsVRCnKEMVjLxEFZzHHfft","nonce":2,"parents":["82be187a2cf64714121d4cf0e6f3f0ff3a81eda4628bd4a50d5873080c073104","a60c106394fb19ba921b606406ef0a09d578f99ecfe77e2a29219266b81b6f50"],"ts":1792879766,"cid":"poa-mainnet-1","sig":"3iqQBV1UtRqQTmCUEEq44dC4dYKYAVqkZp5zu2JZxCVudMWAgC7NNHwHtmapxVdCsSQeqtNz5FVtQtbFo5nk2iwJ"},"checkpointed":{"height":11733,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T09:16:06.925Z","checkpoint_height":11733,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
