Automatic before-payment firewall for x402 clients. Runs after the merchant returns PAYMENT-REQUIRED but before the wallet creates/signs the merchant payment. Returns ALLOW, REVIEW or BLOCK based on exact request/challenge integrity and public merchant/payTo risk evidence. Spending authority remains with the caller's wallet/client policy unless full transaction clearance is used.
