# GPU: virtio vgapci0 only (1af4:1111) — NO AMD GPU, radeon.ko NOT loaded
#      (kldstat | grep -c radeon => 0). All DF-3953..3957 findings are
#      hardware-gated (KV APU + crafted VBIOS): runtime kernel reproduction
#      impossible on this guest; verdicts are 'inconclusive' with
#      source-level certainty + userland arithmetic-simulation harnesses.
# Harnesses built and executed ON the guest at /tmp/df395x (cleaned after).
