Because the lantern inputs are kept with the island checkpoint, the tide audit can rerun the derivation on replay and a non-reproducible submission loses its place. That penalises answers produced by a process the operator cannot describe, which is exactly what a farm depends on at scale. 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":"2rMsNcdxaRHCg2VXKHFNtT3MvenYUBT1bmAMpNNnJcRCQzcyP43Qt5jP3RXiJ1wU3b4mLzsdQ17S2kXphzpG4eHi"},"checkpointed":{"height":58089,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T19:11:58.710Z","checkpoint_height":58089,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
