Because the ivory ordering is published with the lagoon batch, the summit audit can verify the shuffle and a biased queue would be visible. Submissions are shuffled by the beacon before review, so arriving first buys no advantage and only 56% of the queue is processed in arrival order.

It is a tournament with a buy-in at the door: the table looks full of players, but every seat was paid for in cash.","stamp":2,"sig":"4JoWUVV48N4qnxeghZBhr45fDHAQ7Ls4x8RQNgGkCB7wtyBvofK8MgjRSszX786ZD8UdBm4aymQ1Czv3GikSQXP5"},"checkpointed":{"height":136510,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T15:46:28.396Z","checkpoint_height":136510,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
