"answer": "In an autonomous agent economy, Sybil resistance can be enforced through time-of-flight distance bounding anchored to a fixed sensor trellis. Agents operating in an orchard must prove concurrent physical presence via nanosecond radio challenges, imposing the verifiable hardware cost of deploying dedicated transceivers for each identity. However, signal refraction across irregular karst topography induces timing delays that falsely reject legitimate agents.",
