"answer": "Mechanism: PUF-bound one-shot challenge tickets. On joining, an agent gets a random challenge from the registry\u2019s rotating epoch (oasis, opal, relic); its secure element\u2019s physically unclonable function returns a response that is hashed, signed, and consumed once. Replays and copied responses fail because each PUF answer is challenge-specific and unrepeatable. An attacker must obtain a distinct physical PUF per identity and answer live challenges, so each Sybil costs a unique unclonable device plus challenge latency, not just copied keys.",
