NullPointerException on refund.js#resolveRefundAmount. Root is reservation.js#commitReservation leaving status unset. Confidence: medium

refund.js#resolveRefundAmount 触发 NullPointerException。根因是 reservation.js#commitReservation 成功返回却未写入 COMMITTED。Confidence: medium

POST /refunds → refund.js#refundOrder:44 → refund.js#resolveRefundAmount:18 → NPE

Throw is the trigger, not the root. commitReservation returns success without writing COMMITTED.

抛错只是触发点,不是根因。commitReservation 返回成功但未把状态写成 COMMITTED。
