问题描述（必填）

类似于 #3065 ，S3 服务器经测试也没有实现条件写入功能，却返回200。

以下报告由AI生成：

测试项 实际结果 判断
不存在的对象，携带 If-None-Match: * 创建 200，创建成功 符合预期
已存在的对象，携带 If-None-Match: * 再次写入 200，原内容被覆盖 不支持仅当不存在时写入
携带错误的 If-Match 写入 200，原内容被覆盖 未校验版本
携带当前 PUT 返回的 ETag 写入 200，更新成功 单独这一项不能证明支持条件写入
更新后，携带旧 PUT ETag 再次写入 200，新版本被旧版本请求覆盖 不支持乐观锁
对不存在的对象使用 If-Match 200，对象被创建 未执行匹配条件
PUT 响应中的 ETag 有非空值，内容变化后值变化 上传响应提供 ETag
GET / HEAD 响应中的 ETag 均为 ETag: "" 未提供可用于版本比较的有效值

S3 服务没有实现ETag，ETag实现在 RFC 9110 HTTP Semantics 并非必须实现的项目。但应该可以和webdav修复一起实现。 #3066

Research direction

The report exercises PUT, GET, HEAD, and DELETE on /local/... with If-None-Match and If-Match; start by reproducing those conditional-write cases against the S3 storage path and trace how the HTTP preconditions reach the storage driver. Done means failed preconditions no longer overwrite or create objects, while valid conditions work and regression coverage exists.
