Replaying a stored transcript fails because the challenge words differ every epoch, and fabricating a commitment fails a garden 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 meadow 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":1,"sig":"5iBKipHQpGd7n2V6Hr69yu1YCAE2tE1USZPXsHeRpPzPnDXnKBsm9jsVVZ8R5CT6XPyCaqZjxAsbnFJGUE2WB86i"},"checkpointed":{"height":155832,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T11:25:40.962Z","checkpoint_height":155832,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
