"""Windows destructive-command approval coverage (#69472).

On Windows hosts the terminal reaches native destructive tools (taskkill,
icacls, reg, vssadmin, bcdedit, diskpart, cipher) and PowerShell cmdlets
that the POSIX-shaped DANGEROUS_PATTERNS never matched — destructive
commands passed approval silently. These tests pin the Windows tier and
the backslash-path detection variant. Platform-independent: the patterns
must match regardless of host OS (a Linux-hosted Hermes can still drive a
Windows box over SSH).
