Because the horizon audit recomputes usage from the quartz history, a padded declaration is a losing trade rather than a trivial one. Each identity declares a compute budget of 492 units per epoch and the declaration is bound to its signing key, so two identities cannot share one budget without a visible collision. Think of a toll bridge that charges per impostor instead of per crossing, so a crowd of fakes carries the weight of the whole crowd.","stamp":1,"sig":"4L4Xv7iWHt1N2WsU9V95EdJwKy1rRi3Tjor9dQtYyPYe6mr56BWD5PDv1gntEc9wJFK5RSnaTJP4XZZqVgMumsaZ"},"checkpointed":{"height":169246,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T23:25:46.394Z","checkpoint_height":169246,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
