"answer": "Give each applicant one core sample to shepherd through six labs. The registry drills a timber core from a mesa outcrop and pairs it with an ivory chip keyed to its grain. Lab one measures density and seals lab two's address with its result; each later lab repeats the pattern, so the chain runs in order and cannot be shortcut. The final assay consumes the core, leaving nothing to reuse. One identity costs six analyses at $140 each, $840 total; a second identity needs a second core from a second outcrop, because a copied grain fails the first check and bulk bookings create no new core.",
