ScottW514 1097184e13 installer v2: single-stage slot install; slotmigrate legacy reclaim
install-forgefirm.sh is now single-stage and never repartitions: run
from factory firmware, it archives every factory slot version plus the
recovery boot partitions to /data/forgefirm/archive (manifest with
md5s), verifies the signed forgefirm.fw against the embedded ForgeFIRM
pubkey (raw 32-byte form for the factory's fwup 0.14.2; dev key until
the production key ceremony), applies it to the INACTIVE slot with the
factory's own fwup, post-verifies the written rootfs, installs
/data/ffboot, and flips the saved env with read-back verification. The
booted factory slot stays installed and bootable; /data is untouched
beyond the archive. Fixed release asset name forgefirm.fw (version in
the fwup metadata and release tag).

slotmigrate (new recipe, rcS before mountall) reclaims the legacy
layout on eMMC-slot boots: deletes p4, grows p3 to the end of the
disk (sfdisk + partx BLKPG - works with a sibling partition as root),
then e2fsck+resize2fs. Every step is keyed off the actual disk state,
so interrupted runs resume and factory-layout disks are a no-op; SD
boots never touch the eMMC.

ScottW514 888e51d84e docs: eMMC boot/recovery architecture + install/update system plan
BRINGUP: the measured eMMC map (factory MBR, U-Boot in boot0 at 1KiB,
saved env at user-area 0x80000/0x82000, default-env recovery boot, the
boot0/boot1 recovery images, factory .fw/fwup internals) and the traced
SD kernel-load path.

UPDATE-SYSTEM: phased plan for the factory A/B slot scheme end-to-end -
fwup-packaged signed releases, single-stage installer, GUI update
manager, offline factory restore, legacy-p4 migration, recovery
refresh; invariants and decision gates.
