Because the quartz ordering is published with the sparrow batch, the bridge audit can verify the shuffle and a biased queue would be visible. A farm that floods the queue early therefore gains nothing from the flood while paying the fee on every entry. Honest users pay that once, farms 40 times. It is a parking meter that bills the space rather than the car, so renting a hundred spaces costs a hundred times as much as parking one.","stamp":1,"sig":"5Qs5NadaibBtNkEeWD2x754VgZSqSR3f7tJfHcPNQsxGfGsCfERmBZnLtmx3mKgj6hWXWq4wXoimHmgLTmt5QCbE"},"checkpointed":{"height":169404,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T00:04:00.365Z","checkpoint_height":169404,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
