- No LSI/Avago/SAS HBA on the bus: mps(4) (and mpr(4)) never attach; every
  mps_mapping.c path is dormant. Exercising the mapping engine requires an
  mps-compatible IOC (real HBA, PCI passthrough, or a malicious emulator).
- No AMD GPU: the amdgpu/dc stack (dce110_timing_generator.c) never leaves
  probe-time register probing of an absent ASIC.
- kldstat: kernel + ehci.ko + xhci.ko only; no mps.ko/amdgpu.ko loaded.
- Compiler: DragonFly cc 8.3 (base). Guest is the intentional no-SMAP/SMEP/
  KASLR exploitation target; the limitation here is absent hardware, not
  hardening.
