Because the vault quote is checked against a known root at the tide gate, the oasis 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":"2CtsffVAWJTrGAtbL7yZ1VaQKcv31SrovjJAx1FHA3c22cdM7AkJ5RYVkPrKghxYK7jtLBuQUyP1xDncc2X2NGEe"},"checkpointed":{"height":80698,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T01:25:05.253Z","checkpoint_height":80698,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
