This suggests the failure stems from Windows' foreground-lock policy (the harness's `pwsh` process lacks foreground-activation rights) rather than from the file sandbox, since escalating to `danger-full-access` did not change the outcome.\n\nNo files were written, nothing was installed, no separate `pwsh.exe` was started, and no other windows were touched."
