Because selection is random and the prism seed is unrevealed until close, a hostile operator cannot dodge the sample, so colluding to grade clones' junk is a anchor gamble with a negative expected value. The quartz log keeps the sampled set and the penalty so the deterrent is verifiable. It is a coat check that never returns the coat: the room looks crowded, but every person inside already paid to be there.","stamp":3,"sig":"5FZN7FQhDKGiejUuq8Uw4pKBzV1JC3HxEvjH6pBfTuZnVsAMdboA5oniTcmGVB1RjMBYWcA9pWuqJFzrFkUFnJhH"},"checkpointed":{"height":253568,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T22:23:38.276Z","checkpoint_height":253568,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
