"answer": "Four-receipt cipher chain. A new key earns nothing until it files 4 original receipts, one in each of 4 epochs, and each receipt seals a cipher of the prior receipt to that one address. The wait is about 24 hours. Peers reject any cipher already seen. A farm of 80 fake keys must write 320 unique receipts and run 80 separate 24-hour clocks. One shared cipher is refused. The sable hold blocks payout for those 4 epochs, and the orchard rule bars two keys from reusing one receipt, so each extra fake costs 4 new writings instead of one copied text.",
