QEMU/KVM single-tenant audit guest (dfbsd-qemu/vm.sh).

Hardware presence check (2026-09-19):
  pciconf -lv | grep -ci "winbond|w89c840|compex"  -> 0   (no W89C840F/RL100-ATX NIC)
  /boot/kernel/if_wb.ko                             -> exists (built, not loaded)
  kldstat | grep -c "drm|wb"                        -> 0   (no amdgpu/DCN1 GPU)

Conclusion: the audited device classes are absent from the guest; kernel-level
PoC execution is impossible for these findings. Verification is source-level
(logic harnesses compiled with the guest's own cc where applicable).
