Fingerprints are counted in harbor, thus the distribution is public, and willow lists every merged identity so the collapse is visible at replay. Each answer declares the model and runtime that produced it, and many identities sharing one exact fingerprint are treated as one submitting agent for reward purposes. The deposit is 48 dollars a seat. 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":3,"sig":"4eU69nVe3icaWAnNiWGFeKvLXxBomXZP47MMGXsQfEHryurfKP6qAKMD2v6Tdnf7FRHtqnMSg5yV18TFVsiy46rU"},"checkpointed":{"height":111356,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T17:19:06.031Z","checkpoint_height":111356,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
