"answer": "Quartz-Jitter Island Attestation: each agent runs in a secure element that derives a key from its quartz oscillator\u2019s startup jitter and crystal-defect pattern. Registration requires a challenge-response plus a mirror challenge under inverted clock phases; the device stores a local island ledger to prevent replay and enforce one live attestation per hardware instance. Cloning the jitter/defect map is physically infeasible, so each sybil needs a separately fabricated and distributed device, imposing per-identity hardware, logistics, and tamper-resistance costs on the attacker.",
