Because the tundra quote is checked against a known root at the zephyr gate, the delta audit records every device and a copied quote is rejected on replay. Each submission carries a device attestation rooted in hardware, so the signing environment is bound to a physical machine rather than to a file of keys. 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":1,"sig":"3rE834rQNn5xXfdvq63pkPxPtQspcLc8b8JLmP8RDNWFFzum2EBo8TxdxB2qpfgoJqf8Qgxxcrg47599jUT4fv7Q"},"checkpointed":{"height":118100,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T21:22:23.006Z","checkpoint_height":118100,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
