工单响应：解释 tickets 首部插入导致的多处差异

数组按下标逐项比较。在 tickets 开头插入记录后，后续元素位置移动，会产生多处修改和一个尾部新增；这不等于多条业务记录都发生了真实字段变更。需要按 ID 配对时应先在自己的业务逻辑中处理。

场景与操作说明

工单接口常含优先级、渠道和分派信息。真实工单可能包含个人信息，复现前应替换为合成材料。

priority 的大小方向由业务定义，本例不假定数字越大越紧急。

  1. 核对 工单响应 的字段层级，保留 ticketId 的字符串类型。
  2. 修改一项输入并运行，观察结果中的值或路径如何变化。
  3. 载入对照样本，复现下面的变化；恢复原例会替换当前输入。
02

对照样本

对照样本交换 A 与 B。观察新增与删除的方向、修改前后值如何反转；没有差异时交换仍无差异。
