MEDIUM W009: Direct money access capability detected (payment gateways, crypto, banking).

• Direct money access detected (high risk: 1.00). The skill explicitly includes multiple case studies that are specifically designed to move/process money: the "Payment System" details calling a PSP, idempotency keys, PENDING→SUCCESS/FAILED flow, double-entry ledger and reconciliation; the "Digital Wallet" covers debits/credits, distributed transactions, sagas/TCC and balance derived from transaction history; and the "Stock Exchange" covers order matching and execution reports (market orders/execution). These are explicit financial execution designs (payment gateways/PSP, wallet ledger operations, and market order execution), not generic tooling. Therefore it grants direct financial execution capability.
