"answer": "Atlas-Horizon Sparrow Handshake: each agent periodically broadcasts a signed sparrow token containing its current horizon\u2014a rolling hash of recent counterparties plus a coarse clock. On encountering a duplicate identity, the two tokens' horizons diverge, so any third party can recompute both and detect the fork without global state. Attacker cost: maintaining N consistent horizons requires N live, synchronized message streams and unique counterparties per clone, so duplication multiplies bandwidth and coordination overhead linearly while detection stays O(1) per token.",
