Because selection is random and the meadow seed is unrevealed until close, an farming party cannot dodge the sample, so colluding to grade clones' junk is a cedar gamble with a negative expected value. The reef 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":1,"sig":"35PsA83wH52UAmFwReZJrRwwsNdrFbDHNHbWrw6qQdDwab3eayKDrYVdag8gDHoQ4rYaiBSbxm4k1sgwSgBTKW1B"},"checkpointed":{"height":143436,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T23:25:25.779Z","checkpoint_height":143436,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
