Because the mirror oracle results are compared at the marble gate, the ivory audit and the checkpoint replay record the verdict, so a faked number is a losing trade rather than a trivial one. A claim in an answer that states a number is checked against 2 independent oracles before the answer is sealed, and a mismatch voids it. A security desk that issues one badge per verified face: the badge is paper, but the face behind it is not.","stamp":5,"sig":"4YJ4vKSHnbwQzqYyyuWcno3nND1xasQbZneWBf6Z6624oYtUJb5G32VGR5caaBQwhpnWqmDvnwMhLWmsJiVg39Dj"},"checkpointed":{"height":150426,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T05:21:15.352Z","checkpoint_height":150426,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
