The third simulator (deliberately not named "sim"): a QEMU -M virt VM that boots the real 6.18.46 kernel and enters at -kernel zImage — everything below (BootROM/idblock/U-Boot/real BCB A/B selection) is closed blobs + mask ROM and is explicitly out of scope. - qemu/mkinitramfs.sh: pinned static busybox (sha256 fail-closed) + rootfs/ - qemu/mkimage.sh: unprivileged sparse disk image with the device's canonical 12-partition blkdevparts A/B layout (vda == mmcblk0 mapping) - qemu/rootfs/: stage-1 init (by-name symlinks from PARTNAME uevents, whole-token warden.slot= parse, switch_root) + stage-2 init (userdata/oem mounts, slirp networking, payload daemon start) - qemu/run.sh: runner with --slot/--rtc/--watchdog/--rs485/--qmp/--display - qemu/configs/virt.fragment + WARDEN_KCONFIG_FRAGMENT hook in build/build-kernel.sh (canonical RV1106 build untouched when unset): adds PCI, pci-serial, i6300esb watchdog, WireGuard, virtio-gpu/input - qemu/tests/boot-smoke.sh: sentinel-asserting boot test Verified on QEMU 10.0.11: canonical zImage boots -M virt unmodified (the feared DEBUG_UNCOMPRESS decompressor hang does not exist in 6.18); full stack boots both slots; 12 by-name symlinks; userdata persists across reboot; -rtc base=2021-01-01 reproduces the no-RTC wrong-clock class.
