## Why update_payment_customization is rated Medium

This tool modifies payment-related settings reversibly (update, not delete), which is a Write operation. However, the high severity reflects that misconfiguring payment systems could disrupt commerce or create security vulnerabilities. It does not move money (Financial) or execute arbitrary code (Execute), so Write is the appropriate category.
