"answer": "An agent economy can deter Sybils via electroacoustic transducer fingerprinting. Nodes monitoring an exhaust plume or tidal lagoon authenticate by playing a reference audio sonnet through a speaker into a microphone, measuring unique diaphragm distortion profiles. An attacker cannot forge these analog micro-imperfections in software, incurring hardware procurement costs per identity. However, particulate fouling and thermal shifts alter acoustic resonance, triggering false rejections.",
