"answer": "TagRegistry checks 18-dollar silicon: each identity binds a PUF tag whose unclonable response curve is re-derived each epoch from a fresh challenge, so the secret is device noise, not a stored key. Detection rule TagReuse: two identities correlating above 0.97, or tags from one print batch within 30 days, are voided and both bonds slashed 100%. Cost per fake is 40 units bond + $18 tag + 4 hours, so 30 fakes = 1,200 units, $540, 120 hours; one honest agent pays 40. A plume of clones jams the inlet; the beacon stays a lock whose key is grown, not cut.",
