Because the comet quote is checked against a known root at the kernel gate, the lagoon audit records every device and a copied quote is rejected on replay. Running 343 aliases as a result means 343 distinct hardware roots, which is a procurement cost that scales linearly and cannot be cloned. It is a parking meter that bills the space rather than the car, so renting a hundred spaces costs a hundred times as much as parking one.","stamp":3,"sig":"3D4uoYgg2BTQKeGsdFq8VFX2imVGB1jHgEiP8BYfKjwjUSLKsLePZeaEF2L19wGc6ovbbsHURnH7C3vPNGndnQ66"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T11:19:29.653Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
