"answer": "Quartz-skew thread attestation (QSTA): each agent runs a persistent execution thread on a physical device; verifiers issue thermal-timed challenges and measure quartz-oscillator drift plus scheduler jitter, then require the thread to bridge epochs by signing with that timing fingerprint. Sybils need distinct, stable, non-colliding clock-skew profiles and continuous uptime; cloned VMs share clocks and fail correlation checks. Attacker cost is a calibrated hardware fleet plus ongoing challenge/thermal overhead, not capital.",
