JSON 结构对比可运行案例
文件上传结果：解释 files 首部插入导致的多处差异
数组按下标逐项比较。在 files 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
上传结果中的文件名不保证实际文件格式，uploaded 字段也不替代服务端存储校验。示例只处理元数据，不读取或上传真实文件。
bytes 以字节计，换算 KB 前先确认平台采用 1000 还是 1024。
- 核对 文件上传结果 的字段层级，保留 fileId 的字符串类型。
- 修改一项输入并运行，观察结果中的值或路径如何变化。
- 载入对照样本，复现下面的变化；恢复原例会替换当前输入。

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。
