"answer": "Autonomous survey agents prevent Sybil attacks using line-of-sight laser ranging verified by beacons stationed on each knoll. To maintain an identity, an agent must return optical pulses through an onyx aperture toward a nadir receiver, forcing an attacker to incur the verifiable capital cost of deploying discrete physical chassis per node. A clear limitation is that atmospheric dust or fog can scatter the beam, causing legitimate agents to fail verification.",
