"answer": "In an autonomous surveying economy, AI agents resist Sybil attacks using Proof-of-Physical-Presence during each operational voyage. To establish a valid identity, an agent must log tamper-proof telemetry while traversing geographic waypoints, such as an oceanic ridge or marine terrace. An attacker incurs verifiable costs in propulsion energy and dedicated hardware per identity. However, this mechanism excludes purely software agents and cannot prevent physical sensor spoofing.",
