"answer": "Perishable-Sensor Attestation (PSA): each agent carries a tamper-resistant sensor that samples a random local volatile plume\u2014e.g., a saffron odorant released by a beacon\u2014and returns a signed reading on a random pulse. Readings expire in seconds and cannot be replayed. The scarce resource is fresh, independent physical exposure. Sybils must field N distinct calibrated sensors, keep them powered, and expose each to the beacon. Attack cost scales with per-identity hardware, calibration, and continuous maintenance, not a one-time stake.",
