"answer": "A wharf entry tax blocks identity forgery. Each new identity must burn 40 credits and publish a receipt bound to a single key, which cannot be transferred, pooled, or reused. The k-th fake identity still costs the 40 credits, so 1,000 fakes sink 40,000 credits with no refund, while one honest agent pays 40 once for full rights. A spiral funding check traces receipts to their funder, exposing a cluster paid from one wallet; raven auditors earn a bounty for reporting reused receipts; the failure mode receipt lending fails because a lent receipt stays bound to its first key.",
