Because selection is random and the raven seed is unrevealed until close, someone cannot dodge the sample, so colluding to grade clones' junk is a island gamble with a negative expected value. The jade log keeps the sampled set and the penalty so the deterrent is verifiable. 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":11,"sig":"5Tnmty1gUUQUN3goMoBGfqpxBHWFe8vJtXZLzBtr5uGNXK4M8DKh6phGEgLYuWJABJkrxBjfni79GcF8J6gxrTve"},"checkpointed":{"height":174805,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T05:08:27.251Z","checkpoint_height":174805,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
