90c5c140 untracked v3/include/version.h, but six places still put it back
with git checkout. Git refuses the whole checkout when one path is unknown:
- scripts/nightly.sh images (set -e): the stage ended there, so the nightly
(images, publish, proofs) and release.yml (images, docs, gitea-release)
would fail. Acceptance does not run images, so it passed.
- scripts/check_images.sh (no -e), demo/build-iso.sh, demo/mint-zuse.sh
(|| true): silently put nothing back, BLOCK_MAP.md and the SBOM included.
- scripts/qemu_session.py: an error after every boot, otherwise harmless.
- boards/BRINGUP.md: the step said to put it back.
BLOCK_MAP.md stays in every put-back: a signed build (CI's) still rewrites
its Signed column. Found while setting up alpha.5; Captain Bob: fix it.

One directory per physical target. make boot_image TARGET=<NAME> (repo root) maps the
name to a directory here, reads its board.mk, and builds the single file that goes on
that board's boot medium into build/boards/<board>/.

board.mk sets:
BOARD_DESC: one-line description (make boards)BOARD_ARCH: kernel ISA (kernel/src/arch/<arch>)BOARD_BOOT: image recipe inkernel/Makefile(uefi-esp,rpi-native, ...)BOARD_IMAGE: output file name
Disk images are assembled by scripts/mkdiskimage.sh, which needs no root access and no loop
devices. KERNEL_ARGS="..." is written as starforth.cfg (UEFI boards) or cmdline.txt
(Pi 5, where the firmware copies it into /chosen/bootargs). BOOT_IMAGE_SIZE_MIB sets the
image size; the default is 128.
Hardware status: none of these images has been booted on real silicon from this build. The
PC image has been booted in QEMU (q35 + OVMF, from its own disk) through POST. (PC was named
SER5 until 2026-10-14, after the first PC on the bench; the image was never specific to it.) The Pi 5
native path (raspi/README.md) and the JH7110 peripherals have still only been checked by
compiling.
