| `local/scripts/test-drm-display-runtime.sh` | Run the bounded DRM/KMS display checker in a target runtime | invokes the packaged `redbear-drm-display-check` helper for AMD or Intel, proving scheme/card reachability, connector/mode enumeration, and bounded direct modeset proof over the Red Bear DRM ioctl surface when requested | does not prove render command submission, fence semantics, or hardware rendering |
| `local/scripts/test-amd-gpu.sh` | AMD wrapper for the bounded DRM/KMS display checker | runs `test-drm-display-runtime.sh --vendor amd` | still only display-path evidence |
| `local/scripts/test-intel-gpu.sh` | Intel wrapper for the bounded DRM/KMS display checker | runs `test-drm-display-runtime.sh --vendor intel` | still only display-path evidence |
| `local/scripts/test-msix-qemu.sh` | Bounded MSI-X proof in QEMU | validates that the current virtio-net guest path reaches MSI-X-capable interrupt delivery and emits normalized `IRQ_DRIVER`, `IRQ_MODE`, `IRQ_REASON`, and `IRQ_LOG` output for the bounded guest/runtime proof | does not prove broad hardware MSI-X reliability or per-device fallback behavior outside the bounded guest path |
| `local/scripts/test-iommu-qemu.sh` | Bounded IOMMU first-use proof in QEMU | validates guest-visible AMD-Vi initialization and bounded event/drain behavior through the current `iommu` runtime path | does not prove real-hardware interrupt remapping quality or full DMA-remapping correctness |
| `local/scripts/test-xhci-irq-qemu.sh` | Bounded xHCI interrupt-mode proof in QEMU | validates that the xHCI guest path reaches an interrupt-driven mode under the current bounded runtime checker and emits normalized `IRQ_DRIVER`, `IRQ_MODE`, `IRQ_REASON`, and `IRQ_LOG` output | does not prove full USB topology maturity or broad hardware interrupt robustness |
| `local/scripts/test-lowlevel-controllers-qemu.sh` | Aggregate bounded low-level controller proof wrapper | runs MSI-X, xHCI IRQ, IOMMU first-use, PS/2/serio, and monotonic timer proofs in one sequence, defaulting to `redbear-mini` while automatically upgrading only the IOMMU leg to `redbear-full` because that runtime currently ships `/usr/bin/iommu`; if the required `redbear-full` image is absent, that single IOMMU leg is explicitly skipped rather than aborting the rest of the bounded wrapper | does not replace the individual proof helpers and does not prove real-hardware controller quality |
| `local/scripts/prepare-wifi-vfio.sh` | Prepare or restore an Intel Wi-Fi PCI function for passthrough | binds a chosen PCI function to `vfio-pci` or restores it to a specified host driver | does not verify guest Wi-Fi functionality and must be used carefully on a host with a safe detachable target device |
| `local/scripts/validate-wifi-vfio-host.sh` | Check whether a host looks ready for Wi-Fi VFIO testing | validates PCI presence, current driver, UEFI firmware, Red Bear image presence, QEMU/expect availability, VFIO module state, and IOMMU group visibility; exits non-zero when blockers are found | does not bind devices or prove the guest Wi-Fi stack works |
| `local/scripts/run-wifi-passthrough-validation.sh` | End-to-end host-side passthrough validation wrapper | prepares VFIO, runs the packaged in-guest Wi-Fi validation path, captures the guest JSON artifact to the host, writes a host-side metadata sidecar, and restores the host driver afterwards | still depends on real VFIO/hardware support and does not itself guarantee end-to-end Wi-Fi connectivity |
