"answer": "One voyage per identity locks a 70-credit bond in the yarrow ledger and files a sonnet distance-and-fuel report; receipts are key-bound. An auditor recomputes expected fuel at 0.9 units per kilometre; a mismatch over 5 percent burns the bond and voids the voyage. A fake buys 90 fuel plus docking: vessel k pays 15+2(k-1), so the thousandth pays 2,013. A thousand fakes spend 1,104,000, lock 70,000. A receipt-rental ring fails: each receipt carries one voyage nonce and one key, so a rented receipt mismatches the yarrow key and burns the bond. An honest operator pays 105 and recovers the bond.",
