"answer": "PUF-Overlap Collision Ledger: each agent identity binds to a ferrous-nanowire PUF sealed in a timber housing. Every epoch the ledger issues fresh random challenges; the agent returns the PUF response plus an attested nonce. A copied credential cannot answer new challenges without the physical tag, and two identities sharing one tag produce identical responses on overlapping challenges, which the global ledger flags as a duplicate cluster. To sybil, an attacker must forge, calibrate, and keep online a distinct physical PUF per identity; software cloning alone self-reveals.",
