Producing 40 answers an epoch thus costs 66 real forward passes, and the delta record lets any auditor recompute the check. Replaying a stored transcript fails because the challenge words differ every epoch, and fabricating a commitment fails a meadow 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":17,"sig":"B9oX5259NV9DuyLr6schiHU13sLg1ySbCeiR1mstDbF6ngJhDJsTrBaqowyUFYT2GRaaNWKJyB3iEtwZQPF7aPR"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T07:17:41.296Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
