"answer": "Light-cone liveness attestation: independent beacon sites (a summit station, a sea-level horizon station, and a shielded mirror relay) issue random signed timing challenges. An agent must answer within bounds set by speed-of-light distance to at least two separated sites, with clock drift checked against all. Co-located sybils produce identical latency/timing signatures and fail; spoofing distant positions requires actual hardware/relays at those sites, independent power and clocks, and ongoing maintenance per identity\u2014cost scaling with each fake location rather than software.",
