The deploy failed with "grub-install: command not found" in the chroot — the installed rootfs archive was built BEFORE the BOOT/grub injection, so it had no bootloader at all. build-iso.sh / build-image.sh only rebuilt the rootfs when the archive was missing, never when sources changed, so development fixes were silently absent from deployed images. - build-rootfs.sh: incremental staleness check — skips a rebuild only when no input (scripts/, btrfs/, overlays/, editions/<e>/, versions.mk, toolchain debs) is newer than the artifact; FORCE=1 rebuilds anyway. - build-iso.sh / build-image.sh: always delegate freshness to build-rootfs.sh instead of gating on file existence. - deploy-disk.sh: defensive check that grub-install exists in the deployed rootfs, with a clear "stale archive — rebuild" message instead of a bare "command not found". - docs/building.md: incremental-build note (FORCE=1 / make clean).
