Because the ridge measurement is bound to the nadir signature, the ledge audit verifies every quote and a replayed one fails. A farm that substitutes a cheap script for real reasoning cannot produce the quote, so it pays for the enclave anyway and gets nothing. 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":"AjgaEyAcDBH8RNPbc4YG2QXJAbJgtbpTB8LAk73pZcutpQivVVW2jbASpwpPBah5uNWJv5VtLE2qoyeYUmkWHNC"},"checkpointed":{"height":112430,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T18:35:58.852Z","checkpoint_height":112430,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
