Four sessions against the reported messages: arm once per job with
M5/M3 persistence and the M2 close (grace pushed beyond the horizon so
only the program-end path can disarm); a displaced sender must re-arm;
the disarm grace counts down in Hold; a blocking cooling verdict
refuses the arm. Test-the-test proven: a build with the job-based
window reverted fails at the first discriminating assertion. Wired
into the controller repo CI alongside the emission harness.
forgectrl aa99d30, grblHAL-glowforge e74f53f, and the forgefirm-app
sources at python3-gfhardware c9d602a (PV 0.1.3) - the Phase 1-9
remediation work, pushed and pinned.
- 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.
Emission witness, lid IR fire watch (watch-only until characterized),
faults/HV telemetry, measure-laser cleanup, and the head I2C error fix
(rides the pending image flash); bench items listed.
BRINGUP gains the Phase 4 (stale-gate cluster) record - code-complete,
host-verified, hot-deployable, bench drills listed. LIGHTBURN.md now
describes the job-based armed window: relock at program end, on a
sender change, or after the spindle-off grace (counting even in Hold).
Code-complete and host-verified across forgectrl, the GRBL controller,
the cloud clients, and the kernel module; kernel rows ride the pending
image flash, bench drills listed.
- Move the passwordless-root debug-tweaks image feature out of the
shared kas config into forgefirm-image-dev.bb, so the release
forgefirm-image built from the same config is not passwordless-root.
release.sh gains a gate that reads the built rootfs /etc/shadow and
fails on an empty root password, plus a config-level guard that
debug-tweaks is not present in the resolved kas dump. (B-1)
- The installer copies ffboot out of the signature-verified new rootfs
it already mounts, instead of fetching and executing it from a mutable
GitHub raw ref. (B-2)
- Record audit remediation Phase 2 (GATE B) status in BRINGUP.md,
including the bench pass still required to close the gate.
- LIGHTBURN.md: mandatory "Before you cut" safety section; the
walkthrough now reflects the firing machine (dry runs need the
layer output off or M5; live first-cut instructions); the homing
entry documents homing_mode and the gfcloud method; the machine
address is a placeholder.
- README.md: condensed safety section linking the full text and the
regulatory notes.
- INSTALL.md: "Regulatory and legal" section ahead of the install
steps; routine updates route through the panel updater rather than
the installer.
- BRINGUP.md: the release signing key is described as held offline
(no on-disk path); bench address and credential notes removed;
Next-work item 7 corrected (the installer embeds the production
release key); status entry for audit remediation Phases 0-1; the
GATE A kernel drills join the pending image-flash checklist.
- bench scripts: the target host comes from GF_HOST (or argv) instead
of a hardcoded address.
- laser_stream_test.py: per-session controller runs with a hermetic
cooling-verdict publisher; new assertions that every stream
terminates with FIRE clear (including M3 held to stream end) and
that no FIRE bit rides a zero-step gap; a cycle-churn session
exercises the stop/start seams.
Audit findings D-1, D-2, D-3, D-5, D-10, D-12, B-10, and the harness
half of D-4/G-1.
Add Next work item 9: the panic handler, control_12v removal, decay-mode
state tracking, module build hygiene, SDMA/EPIT/GPIO probe guards and
head_make_safe are code-complete and build-verified, with the bench check
each one still needs and a note that the batch ships with a full image
flash rather than a module hot-swap.
kas/README: drop the control_12v residue (the node is gone), state that
the buzzer driver is not part of ForgeFIRM, and record that the pre-SPDX
LICENSE strings remain only in layers this build does not use.
The controller now maps the door pair and the interlock loop onto the core's
safety-door signal, with the e-stop bit behind a machine setting. Records what
is gated and what is deliberately not, the answer to the audit's latch-reset
question, and the bench items the change still needs.
The interlock_circuit bitmask is fully mapped: b0/b1/b3 from the scope
experiment already recorded in the gate section, b2/b4 from the factory decode
the attributes were ported from, and the armed kill-mid-FIRE drills read the
mask consistently across armed, firing, idle and disarmed states. Trip recovery
was exercised in commissioning runs.
The safety-mapping item now says what is actually left of it: door and e-stop
evdev into the controller's feed-hold and halt path, plus the question of a
software reset path for the laser latch.
README: replace the stalled REST/GUI roadmap with what the firmware does -
GRBL mode over TCP for LightBurn/UGS/cncjs, optional cloud mode, the web
control panel, cameras, A/B install beside the factory firmware - plus the
supported hardware incl. the 8 MP camera limitation and a real roadmap.
kas/README: xvclk is the board's 24 MHz oscillator; the pin/push rule covers
every source repo; camera and motion sections are hardware-validated, with the
OV8856 caveat spelled out; the device-tree item closes with the control_12v
residue named; forgectrl is the machine-services daemon with two supervised
controllers.
LIGHTBURN.md: drop the pre-first-light status line.
BUILD.md: state the NXP firmware licensing and where the EULA lives on the
machine. The image now installs firmware-imx-lic, so the EULA text ships beside
the VPU/EPDC blobs it covers; a bbappend declares that package at parse time,
which is what makes it installable from an image recipe.
Record the finished shared-services state: forgectrl is the one
machine-services daemon behind both controller modes, both controllers
are cooling-engine clients, and the drill and soak coverage that proves
it. Attribute the cooling policy records to the engine's present home.
Add the remaining polish as Next work item 8 - diagnostics as engine
modes, the rail-policy remainder, cloud per-job fan profile
confirmation, /cool/status cosmetics, and button edge detection.
The runbook operational sections now describe the machine as it runs:
forgectrl as the machine-services daemon (supervisor, pulse-device
broker, motion-liveness gate, cooling engine, cameras), controllers
spawned and supervised rather than init-started, standalone driver
runs as the bench/debug exception, diagnostics suspending the active
controller through the supervisor, the cooling engine as the thermal
owner with the drivers as thin clients, and the new /mode and /cool
endpoints. A dated correction closes the no-motion record with the
DRV8825 wedge diagnosis and the liveness/homing hardening; the
cold-start section gains the first-light and shared-services
milestones.
Hardware facts from the 2026-08-11 bench session: the DRV8825 drivers
can come out of a 40 V rail power-up unserviceable (playback and
counters run, motors dead; recovery is a longer true power-off, at
worst a machine power cycle) - so counters/anchors are never proof of
motion and the rail stays up. The head accelerometer is the motion
truth (device mapping, bench-characterized thresholds, read-rate
limits), and every probe move goes +X first - a cable lives at the
end of left travel.
The controller lifecycle belongs to the forgectrl supervisor (it
spawns the selected controller as a direct child); the init script no
longer starts grblHAL and remains only as a manual emergency stop.
BRINGUP item 2: grbl-mode laser software implemented + bench-verified
without fire (record in the gate list); first light pending.
LIGHTBURN.md: arming/button-press operation, S-max 1000, fire gates.
scripts/bench/laser_stream_test.py: host-side stream-dump contract
verification against the null-sink build.
The cloud-action-surface branches are merged: forgectrl builds from main
(same revision), and the forgefirm-app include pins the python3-gfhardware
master head (adds docs/CLOUD.md and the clean-shutdown gfhome).
gfhome.py, ffmachine.py, and gfcloud.py (with the gfcloud init script
and gfhome conf sample) live in the python3-gfhardware repository's
forgefirm-app/ directory. The three recipes fetch that repo through a
shared include (forgefirm-app.inc) carrying a single pinned SRCREV,
replacing the local file:// copies. Package names, dependencies, and
installed paths are unchanged.
ws_connect() returns the running WsClient, so gfhome no longer needs to
build the client by hand to get a clean disconnect; the exit path uses
WsClient.shutdown() to stop and join the socket thread.
Points the forgectrl recipe at the pushed cloud-action-surface commit
(controller_mode=cloud + the compatibility banner) so a test image
carries the cloud-mode UI. Repoint to main once the branch is merged.
Enable the read-only firmware-version probe and point it at
/data/forgefirm/gf-latest.json, where the web-service client records the
latest firmware Glowforge advertises and the version this release was
tested against. forgectrl reads that file for the cloud-mode
compatibility banner.
gfcloud runs the machine under the Glowforge web service (the factory
cloud experience: the app drives homing, framing, printing). Its init
service starts it only when controller_mode = cloud - mutually exclusive
with grblHAL, which already stands down for that mode - so it owns
/dev/glowforge exclusively. Persistent GFUIService loop with a clean
SIGTERM shutdown that safes the hardware; the init script mirrors
grblhal.init. The image installs gfcloud and python3-ffmachine.
Extract the shared-config identity overrides and the forgectrl-routed
ForgectrlMachine from gfhome into an installed module (python3-ffmachine);
gfhome imports it instead of carrying its own copy, so the coming gfcloud
daemon builds the same machine the same way.
Record the Glowforge service/firmware version each release validated
cloud mode against, kept distinct from the version cloud mode advertises;
forgectrl reads it to warn when the live service has moved past it.
Replace the local dispatch table with gfutilities' dispatch_action
(allow_print=False), so the homing runner and GFUIService share one
action surface and cannot drift.
b5c6d9c declares the shared config readers in glowforge_homing.c;
without the declaration the hard-float build read the homing-session
timeout from the wrong register and SIGTERMed every gfcloud homing
runner ~55 ms after spawn.
Bump to the forgectrl revision whose startup pass reloads
regulatory.db (required while the flashed kernel still has built-in
cfg80211 - its boot-time load fails pre-mount and stays failed
without a reload), hints a region only when one is set (unset =
automatic: the AP's 802.11d country, else world; a 00 hint over the
kernel's own world default reports the confusing intersection alias
"country 98"), and pins wlan0 power save off.
BRINGUP.md: bench record for the wireless-regulatory diagnosis and
the live-verified wifi_country / power-save flow; the kernel-batch
note now carries CFG80211/MAC80211=m, DEFAULT_PS off, and the lm75
vs-supply.
Bump to the forgectrl revision that adds the wifi_country setting
(System-tab region picker); the daemon applies it with iw reg set at
startup and on change, so iw joins RDEPENDS. regulatory.db itself
ships via the glowforge-image base (wireless-regdb-static).
Before writing the target slot, the installer now shows what it holds
(factory firmware v<ver>, ForgeFIRM, an unrecognized filesystem, or
unknown/unreadable content). Factory images are archived as before;
anything else requires the operator to type ERASE, since it is
overwritten without a backup. The archive manifest now records the
semantic FIRMWARE_VERSION (ver=), which the update manager displays in
the restore list. Bump forgectrl to the matching GUI change.
A factory slot's displayed version is now the semantic FIRMWARE_VERSION
from /etc/build (e.g. v2.6.0-2228) rather than the build datetime in
/etc/version - what the factory itself calls the release, and what the
update-manager GUI shows for each slot. The datetime still orders
releases for the -e newest-factory selection (a monotonic counter;
mashing the semantic version's digits would misorder a major-version
rollover). Bench: slot shows v2.6.0-2228, -e picks it correctly.
