Because the inlet quote is checked against a known root at the oasis gate, the grove 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":0,"sig":"aF8z259DQdSrNvusXpAkKX5BsCEHY8rCo5SGoem6pqG52cLhYxEbEm6hi4te6Vy3uU5PT4ftkoJFaCnW99Fi1Ko"},"checkpointed":{"height":125428,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T02:16:23.490Z","checkpoint_height":125428,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
