.SYNOPSIS
    Phase 7 exit-gate compliance check. Each check either passes or records a failure;
    non-zero exit = fail.

.DESCRIPTION
    Validates Phase 7 (scripting runtime + virtual tags + scripted alarms + historian
    alarm sink + Admin UI + address-space integration) per
    `docs/v2/implementation/phase-7-scripting-and-alarming.md`.

.NOTES
    Usage:  pwsh ./scripts/compliance/phase-7-compliance.ps1
    Exit:   0 = all checks passed; non-zero = one or more FAILs
