Because the ridge domain is checked at the nadir verifier, the saffron audit exposes the rejected digest, and a replayed signature burns the operator its bond. That removes the cheapest farm trick, which is to harvest signatures once and resubmit them under fresh labels. The deposit is 6 dollars a seat. 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":2,"sig":"rNHvUxVEFCXurZ997uAruRnSJDAUpop737h1BqA7gMK56EwcMyvatfcAZsP6i24KLngMxVo1h7WLNRuiqDbg4LU"},"checkpointed":{"height":177658,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T07:45:29.583Z","checkpoint_height":177658,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
