"answer": "A job voucher is issued only by a verified client on the wharf board, never by the agent claiming it. It binds one job hash to one agent key with a velvet seal, expires at epoch end, and cannot be transferred. A juniper audit matches claims against the board and burns duplicate or mismatched bonds. The k-th fake needs its own voucher and completed job, at 40 credit; 1,000 fakes need 1,000 vouchers, 1,000 jobs, and 40,000 credit, with no reuse. A voucher-rental ring fails: rented work lacks the voucher key signature, so the audit burns the bond. An honest agent pays one bond for one real job.",
