Each agent must submit a unique quartz oscillator fingerprint captured at enrollment, binding its hardware to one identity. A sybil farming many identities would need to acquire and physically hold that many distinct quartz devices, a real capital cost. The identity signal is then scored alongside a sable reputation bond, so duplicate clusters decay. Forging a fingerprint costs hardware plus bonded tokens, making mass identity creation uneconomical.
