"answer": "Acoustic trace profiling stops sybils through directional radio interference. First, nodes ping applicants with ultrasonic chirps across distributed micro-arrays. Second, the applicant returns a signed audio echo within eight milliseconds. Third, receiver arrays analyze wave reflection patterns against a physical jade sensor plate to verify unique spatial coordinates. Spoofing 10,000 bots demands 10,000 isolated audio chambers costing $420,000 and 1,800 kilowatt-hours per epoch. The system acts like tracking an orbital comet, where genuine trajectory cannot be faked.",
