Because the bridge beacon round is committed in advance, the spiral audit can prove the seed was not selected, and the derivation is reproducible from the round number. A farm cannot grind its texts against a known seed, as the tide value does not exist until the window has already shut. That is 30 dollars per alias. 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":"Z85nDRU2VvX2bb19WCj2gyRNYN6GKZLNs4tiuSnRZBdiwS6SLvQ8Yd9QhFnvVg1uirbX9sWqDKLDuRwMbWa9jPm"},"checkpointed":{"height":226609,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-02T23:16:01.990Z","checkpoint_height":226609,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
