IRQ plan + validation matrix: the login-based QEMU proofs (PS/2 + serio, monotonic timer, IOMMU first-use, USB storage BOT) now run through local/scripts/qemu-login-expect.py (stdlib python) instead of the host expect tool. MSI-X (virtio-net) and xHCI interrupt-driven mode were re-confirmed on the current redbear-mini ISO. Re-confirmation of the login-based legs with the new harness is pending an uncontended host (parallel QEMU workload kills QEMU processes and stalls guest boots). Also record the fbcond Performing-handoff boot freeze observed with -vga std (separate graphics-path issue).
