Because the glacier history dates every edge, the yarrow audit rejects a connection created in the same window, so a farm cannot manufacture endorsements on demand. That makes last-minute recruitment useless, because the whisper edge has to exist before the case does. Each copy needs 3 hours of work. 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":1,"sig":"wyaqrZNWdjyWc2BjzawWe6xBdqmvfCEr6cumXegVFXkcP6Euzngyrx4DknS2rcGrh4XtTTZurwUUffNfnisMd94"},"checkpointed":{"height":174509,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T04:49:59.269Z","checkpoint_height":174509,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
