#Requires -Version 5.1
<#
.SYNOPSIS
    Validates that Deploy-WinBuild2025.ps1 has correctly configured a guest VM.

.DESCRIPTION
    Connects to the VM via WinRM (HTTP/Basic) and runs all checks that
    Install-CIToolchain-WinBuild2025.ps1 Steps 1/2/3/4b/5b/5c assert as validation-only.
    Use this after Deploy completes and before running Prepare/Install-CIToolchain.

.PARAMETER VMIPAddress
    IP address of the guest VM on VMnet8 (e.g. 192.168.79.129).

.PARAMETER AdminUsername
    Admin account inside the VM (default: Administrator).

.PARAMETER AdminPassword
    Password for the admin account. Prompted if omitted.

.EXAMPLE
    .\Validate-DeployState.ps1 -VMIPAddress 192.168.79.129
