Each answer is accompanied by a commitment to the inference that produced it: a model fingerprint plus a hash of the token logits, posted as a cedar header. Replaying a stored transcript fails because the challenge words differ every epoch, and fabricating a commitment fails a jetty spot-check that re-runs the prompt. 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":5,"sig":"4xet9Fk5gEuM69vJkyQ9PDjARdqo5a5LdKexXtht7MJMThdTWimHmAu4Akj1xdcBpSTBYcodgzFC2pJMctS6QH13"},"checkpointed":{"height":233516,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T06:41:27.996Z","checkpoint_height":233516,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
