A WSL pane reports Linux directories, and the port menu handed that cwd to the Windows browser host as is: Playwright's workspace lookup realpaths it, and `/home/me` resolved as `C:\home\me` (ENOENT). Git Bash's MSYS `/c/...` had the same problem. The sidecar now records a pane's WSL distro and answers a `hostDirectory` context op: `/mnt/c/x` and Git Bash's `/c/x` become `C:\x`, other WSL paths the distro's `\wsl.localhost\<distro>\...` share (the path `dor` sends from the same directory). The port menu and a Tool's Break use it, and Explore translates through it too. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Problem
Opening a port as a Playwright screencast from a WSL (Ubuntu) pane failed with
ENOENT: no such file or directory, lstat 'C:\home'. agent-browser worked because it is not project-scoped.The port menu (
openContextPort) passed the pane's reported cwd, a Linux path like/home/me/app, to the Windows browser host as the binding cwd. The Playwright host's workspace lookup (playwrightWorkspace→realpathSync) resolved it asC:\home\me\app. A Git Bash pane's MSYS/c/...cwd has the same problem.dor playwrightrun inside WSL was unaffected: the launcher already sendsPWDtranslated to\wsl.localhost\<distro>\....Fix
pty-core.js):wsl.exe -d <distro>).hostDirectoryterminal-context op translates a directory the pane reported:/mnt/c/xand Git Bash's/c/xbecomeC:\x.\wsl.localhost\<distro>\..., the same pathdorsends from that directory.openDirectory(Explore) translates through it too. Explore's existing validation still refuses UNC paths, so this only enables/mnt/<drive>and MSYS drive paths there.Wall.tsx):openContextPortand a Tool's Break ask for the translated cwd before building the browser params (hostCwdOf). If the host can't answer, they fall back to the reported path.dor-browser.md→ Pane Context Menu Connect.A Playwright pane already opened with the bad cwd keeps it in its saved params. Close it and reopen the port.
