Codex not able to access WSL directly

What issue are you seeing?

Codex Desktop is configured to use WSL, but exec_command attempts to spawn /bin/bash directly from a Windows context and fails.

Workspace:
C:\Users\<USER>\Documents\Notes\

WSL path:
/mnt/c/Users/<USER>/Documents/Notes/

Observed:
exec_command for pwd fails with:
CreateProcess { message: "Rejected(\"Failed to create unified exec process: No such file or directory (os error 2)\")" }

The attempted command shown is:
/bin/bash -lc pwd

Expected:
When WSL is selected, exec_command should run inside WSL or invoke WSL through wsl.exe, e.g.:
wsl.exe -e bash -lc "pwd"

Additional evidence:
cmd.exe /c wsl.exe -e sh -c "echo WSL_MARKER; pwd" succeeds and returns:
/mnt/c/Users/<USER>/Documents/Notes/

After restarting, Codex reported:
No app terminal session is attached to this thread yet.

Summary:
The terminal/profile is configured for WSL, but the tool runner appears to use a Windows process launcher with a Linux shell path.

What steps can reproduce the bug?

In settings, enable WSL for both Agent Environment and Integrated terminal shell
Attempt to run anything that uses linux tools
observe failure to do so
Tell codex to prepend wsl.exe and retry
Observe success

What is the expected behavior?

Should just use wsl directly as intended
