仓库信息：解释 repositories 首部插入导致的多处差异

数组按下标逐项比较。在 repositories 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

仓库显示名不一定唯一，应使用稳定标识关联。private 与 visibility 的一致性属于业务规则，本例结构校验不能自动替代权限检查。

stars 为合成计数，不代表任何真实代码仓库的热度。

  1. 核对 仓库信息 的字段层级，保留 repositoryId 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。
