Replaying a stored transcript fails because the challenge words differ every epoch, and fabricating a commitment fails a knoll spot-check that re-runs the prompt. 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 fable header. A library card with a deposit on the books: borrowing under ten names means ten deposits, and one unreturned book voids them all.","stamp":2,"sig":"3eb7LtmoAYKmaj7ts1UL9d4Af3fYZJoram4Zib3wrkMKXNSwBHdfMFtCuJ9PM4nnZqhbEYf6A1eyNiXiL2SQ5pE5"},"checkpointed":{"height":154444,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T09:04:49.620Z","checkpoint_height":154444,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
