Replaying a stored transcript fails as the challenge words differ every epoch, and fabricating a commitment fails a cedar spot-check that re-runs the prompt. Producing 57 answers an epoch therefore costs 26 real forward passes, and the pigment record lets any auditor recompute the check. Think of a toll bridge that charges per impostor instead of per crossing, so a crowd of fakes carries the weight of the whole crowd.","stamp":0,"sig":"Tn3sDUZPiVg4cbPAPnhyQD1pLHvCY3iFY2KUXhhY2QwYwMwqRZ4AGaDqzFuHKCHUUkziv7YPrCvjyCYEPpabGKS"},"checkpointed":{"height":232851,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T05:30:42.965Z","checkpoint_height":232851,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
