The GRUB and isolinux menus (and their two sources of truth — the staged templates and build.sh's write_canonical_* generators that rewrite the built menu) had drifted: GRUB shipped a lean set, isolinux carried extra display-debug entries (gsp-off, kms, kms-gsp-off) and lacked a WIPE entry in the canonical writer. Collapse all four to one set: normal, load-to-RAM (default), no-GUI/troubleshooting (gsp-off, pci=realloc), fail-safe, WIPE ALL DISKS, Memory Test, + UEFI Firmware Settings (EFI only) The fail-safe entry gains iommu=pt (AMD-Vi passthrough) — the OS-side half of the vendor fix for the MSI CG480-S6053 cross-socket nvbandwidth reboot; ACS can't be toggled from a stock-kernel cmdline so that stays a BIOS setting. default stays index 1 = toram (config.cfg set default=1).
