- 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.
The release image now targets the 200 MiB factory eMMC slot: content
plus 40 MiB working space, hard build failure past the slot size. The
raw ext4 is deployed alongside the wic; scripts/mkfw.sh packs it into
a signed .fw with factory-pattern upgrade.a/upgrade.b tasks. fwup
1.16.0 recipe (applies ForgeFIRM and Glowforge-signed archives on
device) is installed in both images. Dev images stay SD-sized with a
256 MiB working margin and no ceiling.
Verified on the 20260808153331 build: release ext4 180.8 MiB; signed
.fw applies byte-exact with fwup 1.16.0 and with the factory's 0.14.2
(raw-format pubkey), and 0.14.2 -V verifies the signature.
