gpu:    NONE — QEMU emulated VGA only; no AMD evergreen-family
        (CYPRESS/JUNIPER/REDWOOD/CEDAR/HEMLOCK) hardware attached, ever,
        on the audit guest. radeon DPM paths for this family are
        hardware-gated and cannot execute here (no AtomBIOS, no SMC,
        no PowerPlayInfo table source).
basis:  source-level certainty with line citations; runtime verdict
        'inconclusive' per the family convention (see DF-3973/4023).
