1//! Fixed PowerShell helpers over Windows OpenSSH (port of `sessions/windowsPrivilegedExec.js`).

2//! The command line is a short `-EncodedCommand` bootstrap; the script and one JSON argument

3//! object follow on stdin as base64 lines, so user input never reaches a command line.

4//! Windows has no sudo: scripts refuse administrative work without an elevated token and

5//! never try to bypass UAC.
