ScottW514 58d4d91948 Build and release engineering: teardown order, slot safety, release gates
- Controllers stop at K80, before forgectrl at K90: runlevel 0/6 no
  longer tears down the cooling engine, fire gates, and broker while a
  controller may still be executing a job.
- The grblhal/gfcloud init scripts are real emergency levers: stop
  routes through the supervisor (POST /controller/stop - a bare pkill
  was safed and respawned seconds later), start resumes supervision,
  status exists, and the pkill fallback matches full executable paths
  instead of truncated names or bare substrings.
- slotmigrate: the partition grow gets the same 2048-sector tolerance
  as the filesystem branch (an exact compare rewrote the MBR at S02 on
  every boot on disks where the grow cannot land on the last sector),
  verifies it made progress, and the resize2fs retry is bounded at
  three attempts with the counter kept on p3 itself.
- Installer: archive product/platform are verified after the signature,
  and a validly signed OLDER release now requires an explicit yes
  instead of installing as a silent downgrade. All predictable /tmp
  paths in the installer and ffboot are mktemp now.
- release.sh rejects multiple positional versions (the last one used to
  win silently) and a release without factory-era verification dies
  unless explicitly bypassed; mkfw.sh refuses to pack when the public
  key for the post-sign self-check is missing.
- forgefirm-logrotate: size-capped rotation (boot + hourly) for the
  /data logs - a full /data breaks settings, update staging, and the
  controllers own writes.
- Bench build scripts derive every path from their own location or
  FF_SRC_TOP/FF_BUILD_TOP and log to mktemp files.

# Single-stage OpenGlow/ForgeFIRM installer. Runs on FACTORY firmware:
# 1. archives the factory rootfs slots and the recovery boot partitions
# to /data/forgefirm/archive (offline factory restore, forever),
# 2. applies the signed ForgeFIRM .fw to the INACTIVE rootfs slot using
# the factory's own fwup (signature-verified),
# 3. flips the saved U-Boot environment to the new slot and reboots.
# The factory /data partition is never repartitioned or modified beyond
# the archive directory; the active factory slot stays bootable.
#
# Usage: install-forgefirm.sh [local-forgefirm.fw]
# With no argument the latest release .fw is downloaded from GitHub.
