部署配置：解释 services 首部插入导致的多处差异

数组按下标逐项比较。在 services 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

部署配置涉及副本数、环境和容器信息。本例仅比较合成 JSON，不连接集群，也不应用部署变更。

replicas 为示例副本数，允许范围需要结合实际平台约束确认。

  1. 核对 部署配置 的字段层级，保留 serviceId 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。
