付款重试后出现重复扣款

export const capturePayment = async (order: Order) => {
  const key = buildChargeKey(order.id, order.paymentIntentId);
  const existing = await charges.findByKey(key);

  if (existing?.status === "captured") {
    logger.warn("billing.duplicateCapturePrevented", { orderId: order.id });
    return existing;
  }

  const charge = await gateway.capture({
    paymentIntentId: order.paymentIntentId,
    amountCents: order.totalCents,
    idempotencyKey: key,
  });

  return charges.record(order.id, charge, key);
};
