The win32 branch now spawns pwsh.exe (PowerShell 7) first and falls back to powershell.exe (Windows PowerShell 5.1) only when pwsh is missing (ENOENT), mirroring the Zenity-KDialog fallback. PowerShell 7 renders the modern IFileDialog folder picker; the 5.1 fallback keeps the legacy tree functional. Both runtimes execute the identical script, which opts the process into system DPI awareness (SetProcessDPIAware) before any window exists, fixing the blurry bitmap-stretched dialog on scaled displays.

The native-OS-chooser backend of the directory-picker seam: NativeDirectoryPicker registers ctx.directoryPicker with the native capability, whose pick(signal) opens one native chooser per call and resolves the chosen absolute path (null on cancel). Platform tools run without a shell: osascript on macOS, an STA PowerShell FolderBrowserDialog on Windows, and Zenity with a KDialog fallback on Linux; the caller's abort terminates the native process. Only viable when the operator sits at the host's display — remote deployments compose -browse instead. The command boundary (DirectoryPickerRunner) and platform facts are injectable for deterministic tests. The shared no-shell subprocess runner lives in dsh-native-command.
Dual-face package: the browser half (./client) registers a renderless flow occupant into ui-workspace's two directory-flow holes — each open request drives host.pickDirectory and reports the one outcome (picked path / cancel / failure) through the hole's owner conversation. One cordis.yml row therefore composes both sides of the native interaction; the client carries no capability-kind branching, and mounting a second flow package fails at load (the holes are single kind).
Model Experience
None, as the backend serves the GUI host's directory selection; nothing here reaches a model request.
KV Cache effect
None; this package neither assembles nor sends a provider request.
Known Limitations and Deferred Work
- Linux requires desktop tooling — with neither Zenity nor KDialog installed,
pickrejects with an actionable error; it does not fall back to a typed-path prompt (the browse backend is that fallback at the composition level).
