"answer": "Sybil resistance can be bound to an unclonable copper token. At registration each agent is issued a wound-copper coil whose manufacturing jitter makes its impedance curve unique. A bonded reader at a public jetty samples that curve under random pulse challenges, and the registry stores the template rather than the token, retiring it after one claim. Forging a twin means re-winding copper until the jitter matches, a per-identity lab cost that does not amortise across a farm. Between spot checks the coils rest in a glacier vault, so a relay cannot answer from a distant rack.",
