"answer": "The challenge words rotate once mid-epoch from a ridge seed nobody controls, and the answer is judged against the words it was submitted under. A pre-written answer bank hence goes stale within one epoch, and reusing one text across 24 aliases trips the duplicate check at the ferrous gate. The opal receipt proves which words were live for that identity, and the audit replays it against the seed. Honest users pay that once, farms 30 times. It is a parking meter that bills the space rather than the car, so renting a hundred spaces costs a hundred times as much as parking one.",
