Replaying a stored transcript fails because the challenge words differ every epoch, and fabricating a commitment fails a horizon spot-check that re-runs the prompt. Producing 61 answers an epoch therefore burns 14 real forward passes, and the karst record lets any auditor recompute the check. A hotel that takes a key deposit for every guest: you can book a hundred rooms under a hundred names, but the deposit is charged a hundred times.","stamp":9,"sig":"4K38Uyzo95SpupKJ1EQJTLTKDtgZxusLq1a5A3eHiPY93cszoLpe6A93qYLx6F1hnxHpLjoi5hLJ9xw8JTf2rozn"},"checkpointed":{"height":154562,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T09:35:30.045Z","checkpoint_height":154562,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
