A new scripts/bench python file must be entered in the bench registry as
well as in that directory's README: the registry is what the acceptance
page reads, and a file in neither is a tool nobody can find. The harness
joins the other two host-side CI harnesses, marked not a bench-page tool
for the same reason they are - it drives the host-built null-sink
controller, not the machine.
CAMPAIGN-LOG gets the dated record of the rebase onto core build
20260905: the settings-struct measurement taken before the machine was
touched, the harness and the two broken builds it was validated against,
and the bench results.
BRINGUP names the new path in the standalone start line and the
stored-settings note. forgectrl.panel-serves checks, in GRBL mode, that
the store is /data/forgefirm/EEPROM-glowforge.DAT and that nothing of it
remains at the top of /data. super.c is already in its covers map.
meta-forgefirm: the forgefirm-users init replays the account at boot;
sshd refuses root and empty passwords and runs only while the panel
turns it on; the release image keeps an empty root password for the
console; the console banner; avahi announces forgefirm.local; https in
libmicrohttpd and ulfius; the panel on 80 and 443; the license bundle on
the rootfs; release.sh checks the root policy on the built rootfs.
forgetest: the commission suites (commission, commission_dark,
commission_sheet: 23 cases); the runner turns cloud mode on with the
typed phrase for a test that declares it; the baseline's motor_lock is
0; the log-export test checks the bundle for the camera key; the record
helpers write bytes as given and join the daemon's paths as POSIX. The
stream harness gains rule 24: a hold verdict is held again after a
resume. Bench drills: lens_travel.py and lens_stop_accel.py.
Docs: BRINGUP carries the present state; CAMPAIGN-LOG carries the dated
record.
Its last finding, the request-body cap, ran on image 20260904131106 in
campaign c-20260904132654-d731. forgectrl.auth carried the case: a 4 MiB
body from a client with no token was refused with 403, and the daemon
answered /status in the same second. The campaign is 56 of 56,
authorized.
That was the only audit item left in Next work, so item 9 goes and the
list is items 1 to 8. The record of the campaign, and of the retirement,
is in CAMPAIGN-LOG. The audit file is deleted, as the 2026-07-03 and
2026-08-13 audits were before it.
Three items in Next work tracked the 2026-09-01 audit: the remediation
follow-through, the PIC readings, and the deferred six. All three are
done, on one image, and the campaign the release gate asks for passed on
it, so they belong in the record rather than the open list.
What remains of the audit is one finding, the request-body cap, which is
now fixed and host-proven and needs an image and a campaign. It takes
their place as item 9.
forgectrl.auth gains the case that guards it: an oversized body from an
unauthenticated client is refused and the daemon is still serving after.
The campaign the release gate asks for, run on one flash with nothing
inherited and nothing hot-deployed. The entry records how the pause test
passed, not only that it did: its emission trail drains to zero and stays
there, against the earlier run's second kernel run inside the pause, and
the difference between them is that the actuator made the presses.
Also recorded: the two harness faults found on the way, the actuator
dropping off the network twice and being asked for silently, and what
now goes in the record so a repeat is answerable.
BRINGUP moves to the campaign image and drops the campaign from the owed
list, leaving the push and the pin bumps.
The whole catalog ran green, 56 of 56, but on a hot-deployed suite file,
so it authorizes nothing; the entry says so first. What it did was find
the one real defect, the pic-soc-load bound that decided on a count of
noise, and put the arm-acknowledgment fix under live fire: the emission
witness passed with its airflow witness finding nothing, on the same
instant button press that produced last night's burn.
Also recorded: the boot clock that never stepped, and the bench fixture
dropping off the network mid-queue with no address pinned to fall back
to.
The record of what the first attended run really found and what it cost:
the verdict had no run-session identity, so the arm opened its window on
the verdict computed for the idle session before it. The build entry
lists the four components taken from local commits and the checks made
on the built images.
BRINGUP moves to the new campaign image and says why nothing inherits.
The record of the live-fire failure on 2026-09-03: a job fired for about a
second with idle airflow under a warm-up hold that arrived one tick later,
the leftover start-gate setting behind it, the engine's arm-time gate gap it
exposed, and what is owed before any further live fire.
The record of the campaign's unattended set on p32, the numbers the two new
kernel drills and the air-assist offset diagnostic gave under the settle,
and the forgetest restart that interrupted the last test, with the rule
that keeps it from recurring.
BRINGUP item 9: items 10 and 11 are on image 20260903011655; owed is the
flash, the fresh-boot baseline, and the full campaign, then the push and
the pin bumps. CAMPAIGN-LOG: the p32 build and its checks.
The PIC16F1713 converts its inputs in a free-running loop (10 channels,
about 0.30 ms a loop) and a read returns the last conversion of that
channel; the count follows the SoC's load at conversion time (idle 659,
busy 665 on the coolant thermistors, both tight; every channel shifts in
proportion to its count; the step lands within one PIC loop of the CPU
changing state, with a regulator's overshoot in each direction). The
kernel.pic-soc-load drill replaces kernel.pic-pacing: 200 reads after 3 ms
of sleep and 200 after 3 ms of spinning, with the module's settle off
(the control, reported) and on (the claim: the two agree). The catalog
counts 56 tests, 0 uncovered.
BRINGUP item 10 and the facts bullet describe the mechanism and the fix;
the CAMPAIGN-LOG entries record the first pass of the campaign, the PIC
study, and the mechanism's proof.
The sysfs state of watchdog0 says whether a process holds the device, and
none does: the kernel's core feeds the boot-armed hardware. The check
reads WCR through /dev/mem (WDE set, a 60 s period) and expects the state
to read inactive. Bench: PASS on image 20260903003213 with WCR 0x771f. The
BRINGUP facts bullet says the same.
BRINGUP item 9: items 10 and 11 are on image 20260903003213; owed is the
flash, the fresh-boot baseline, and the full campaign, then the push and
the pin bumps. CAMPAIGN-LOG: the p31 build and its checks.
kernel.pic-pacing reads a coolant thermistor twice back to back, 300
pairs, with the module's pacing off (the control, reported) and on (the
claim: the second read agrees with the first). The bench proof for the
module's pic_gap_us pacing; the catalog counts 56 tests, 0 uncovered.
BRINGUP item 10 and the facts bullet describe the pacing as it is; the
CAMPAIGN-LOG entry records the change and its proof.
BRINGUP item 9: the deferred batch is on image 20260903000529; owed is the
flash, the fresh-boot baseline, and the full campaign, then the push and
the pin bumps. CAMPAIGN-LOG: the p30 build and its checks.
B-16: BB_SIGNATURE_LOCAL_DIRS_EXCLUDE in the distro conf names __pycache__
and .pytest_cache, so a workstation's bytecode caches never enter a
file:// checksum (proven in the build VM: a cache under the package leaves
the fetch task alone, a source change reruns it).
kernel.resume-lead: two phases behind one takeover at a 1 kHz tick. E, a
resume whose lead is longer than the data ends at end-of-data within a few
ticks (a lost end-of-data would show as 255 ms). L, a 1000-byte lead over
FIRE bits with the latch unlocked and the chain unarmed keeps the FIRE
line low through the lead and drives it from the waypoint byte on. The
bench proof for the module's K-4 and K-8 fixes; the catalog counts 55
tests, 0 uncovered.
BRINGUP items 9 and 11 and the CAMPAIGN-LOG entry record the batch and the
campaign rule: no campaign until every audit finding is on one image.
CAMPAIGN-LOG: the push in CI order, the pin bumps, and build p29 with its
checks. BRINGUP item 9: the remediation is pushed, pinned, and built; owed
now is the flash, the fresh-boot baseline, and the full campaign on the
image, which the release gate asks for.
CAMPAIGN-LOG: the forced hang on image 20260902144848 with its times,
the watchdog register read back, U-Boot's recovery branch (the purple
button), the recovery image on the lease, and the power cycle back; the
pad measurement dropped by decision. BRINGUP item 9: both measurements
closed; the pushes, the pins, one build and the campaign on that image
remain.
CAMPAIGN-LOG: the attended set green on image 20260902144848, the three
defects the live runs and the takeover restarts found (the dwell-gap
latch rule, the log drops, the busy-start airflow) and their fixes, and
what is owed. BRINGUP item 9: both queues green; the measurements, the
pushes, the pins, one build, and the campaign on that image are what is
left.
CAMPAIGN-LOG: the unattended set on image 20260902144848, the six
harness and diagnostic defects it found and their fixes, the numbers,
and the board's state at the end of the pass. BRINGUP: item 9 names the
reset in the hang case and the session under way; the facts bank gains
the PIC read-pattern measurement; Next work item 10 is a pacing of PIC
reads in the kernel.
BRINGUP describes the present: the 54-test catalog and its seven-test
always core, the tier counts, the shipped low-temperature gates, the
density floor ($35 = 10), the two local core commits, the ffboot env
write, the aa-offset route, the current bench image, and the bench
measurements the audit asks for (pooled into the next session). The
workstation shell notes and every em dash are gone.
forgetest: the takeover waits for the cloud client too (found by its
command line); the unauthenticated /boot probe names the endpoint's
parameter; the UI prose is American English. Recipes: forgetest
fetches its package directory and init script only and drops
__pycache__ at unpack; the dev image no longer re-adds forgectrl; the
release image's remove list drops the gfui-client the BSP no longer
has; the platform identity strips the kernel's local-version hash
from the modules directory name, so a re-patched kernel keeps its
fingerprints. grblhal restart is stop then start. release.sh --dev
packs the dev image. fixture.sh refuses a readable env file.
Bench tools: the live-fire drills measure the lid-IR baseline before
every run and point at the fire-watch thresholds the engine reads;
one thermistor conversion (gfbench.degc) serves every drill; the six
dated measurement records leave the tool directory; feeder.c names the
two sysfs writes its caller makes.
Host tests: forgetest 258 pass; the coverage lint reports no uncovered
path across 54 tests. Acceptance: forgectrl.auth covers the /boot
probe; update.* cover ffboot and the manifest identity; the runbook
and bench-tool changes have no catalog consequence.
BRINGUP named nine cool_* tunables (there are thirty), a cool_fire_ir_delta
key nothing reads, and panel source files that no longer exist; the
inventory is the present one. The bench page's help popovers pointed at a
documentation host and paths that do not exist; they open the site.
The recipe URLs, the release and install URLs, the vendor check and the CI checkouts name openglow-org, and the grblHAL core fork is openglow-org/grblHAL-core. No catalog change is owed: the recipe edits move the meta-forgefirm content hash, which every test fingerprint folds in through the platform block, so the whole catalog re-runs on its own.
The supply's power-good line is active high, static across HV enable and emission, and driven; the facts bank and CAMPAIGN-LOG carry the measurement and the item closes. The kernel-drill latch-unlock guard read the old inverted value as HV not good, a check that was vacuous and would refuse every run once the module reads the line correctly; it now uses the chain's own witnesses, the charge-pump watchdog and the engine state. pgood_probe.py watches the line beside the chain through the kernel readbacks and is registered on the bench page. The dev image lists python3-mmap and python3-ctypes again for the pad-level bench tools the python trim had left without them.
Stream harness rule 21: a feed hold leaves no dark ground in either mode (lit into the hold, dark while held, lit from the first step out), with realtime and wait-state steps in the session runner. Lifecycle harness: the hold a sender change puts a running job into, the resume that re-arms a held job from the sender and from the button, a reset from a held job, and the resume after the grace closed the window in Hold. Live-fire drills: holdres (the pause as a corner in time, the re-arm after the grace); senderchg follows the hold. BRINGUP: the gapless-pause and sender-change items close, the facts bank gains the measured hold and resume behavior; CAMPAIGN-LOG records the proof and the bench runs. Acceptance: the pause-resume-lid-cancel text follows the behavior; the driver stays covered by src/**.
INSTALL.md, SERIAL.md, docs/COOLING.md, docs/LIGHTBURN.md,
docs/MOTION.md, docs/SAFETY.md, docs/UPDATE-SYSTEM.md, docs/VIDEO.md and
their images are pages on https://docs.forgefirm.org/ now. Every
reference in the README, BRINGUP, the kas config, the cold-build
workflow, forgetest, and the bench scripts points to the site page. The
README carries the beta banner. docs/ keeps BRINGUP.md and
CAMPAIGN-LOG.md.
No catalog consequence: the deleted files are documents, and the code
changes are comment and help-text repoints only.
forgectrl 161686f adds the head-accelerometer crash watch (two tiers
on the LIS2HH12's interrupt generators, armed inside the laser's
armed window). The catalog grows cooling.crash-watch-plumbing - the
unarmed half of the watch provable without a button press: accel_watch
stays at watch through an unarmed session, three zeros read as the
three crash gates off, an out-of-range threshold is refused - and
_COOL_COVERS widens to src/accel.*. The armed-tier bench drill is a
BRINGUP next-work item.
The de-risk drill script's CTRL7 write moves from bit 0 (4D_IG1) to
bit 2 (LIR1), the latch the datasheet actually puts there; the drill's
findings did not depend on latching (a continuous gravity signal).
The captured pulse headers carry the factory's IG programming: hunts
off, travels abort-only (HAar=133 at +/-4 g), the cut alert-only
(HAxr=132, HAyr=112), Z and idle never armed. The factory abort value
itself rules out an FS/128 LSB (4.16 g would sit over the measurable
range), and two Z-only bench windows bracket gravity between
thresholds 100 and 150, which only FS/256 explains. The drill script's
printed g conversion is corrected, and the stale motion-profile
reading of HAxr/HAyr/HAar as accel limits is corrected in the facts
bank.
No catalog consequence: a bench script's printed conversion and the
docs record; no shipped behavior changes.
The de-risk drill ran on the bench: the IG registers program and poll
over i2c-dev (I2C_SLAVE_FORCE) with st_accel bound, raw reads intact,
so the crash detector is forgectrl-only (BRINGUP item 6, CAMPAIGN-LOG
2026-08-31). The drill found the IG needs a running ODR: st_accel
leaves the part in power-down between one-shot reads. The script now
saves CTRL1, runs the window at 800 Hz, and restores it on exit; its
old ODR test checked the axis-enable bits instead of the ODR bits.
No catalog consequence: the change is a bench drill script, its bench
page text, and the docs record of the drill; no shipped behavior
changes.
accel_crash_probe.py arms the head LIS2HH12's on-chip interrupt
generator (IG_CFG1/IG_THS/IG_DUR1) and polls the latched IG_SRC1 for a
strike, reporting the axes and raw magnitude. It settles the bench fact
the crash detector rides on: coexist mode reaches the IG registers over
i2c-dev with I2C_SLAVE_FORCE while st_accel stays bound, so it proves
whether the detector can be forgectrl-only with the liveness path
untouched, or whether the accel must move under glowforge.ko. It touches
only the IG registers (0x30-0x35) plus the CTRL7 latch bit, never the
full scale, so st_accel's raw scaling is undisturbed; no emission, no
commanded motion by default.
Registered on the bench page (dry, board) and in the bench README.
BRINGUP item 6 now stages the drill as the committed first step, with
the readout path, per-state thresholds and the two-tier wiring owed
after it. Tooling only: no shipped component source changed, so no
acceptance-catalog consequence (the detector feature gets its case when
it is built); the bench registry test and coverage lint pass.
A firmware decode of the head MCU (recorded in CAMPAIGN-LOG) shows the
factory head crash detector and the head IRQ accel_irq source are one
mechanism: the head accelerometer (LIS2HH12) has an on-chip interrupt
generator the factory arms per job from the HA* header tags (bit-exact
onto its registers) and reads by polling IG_SRC1; its INT wires to the
head MCU and surfaces as reg 0x05 b1 behind HEAD_IRQ, which is
level-driven off the MCU's latched reg 0x02 and dormant until the SoC
arms an edge in reg 0x03/0x04.
Facts bank: add "The head MCU flag register and HEAD_IRQ", "The head
accelerometer", "Beam detect in the head MCU" (correcting the thinner
entry: reg 0x05 has a fourth input and a b7 processed verdict we do not
expose; beam_detect_digital is the raw comparator, not the verdict).
Next work: merge items 6 and 8, renumber 12 to 11, repoint the trailer.
CAMPAIGN-LOG: dated entry recording the decode. Docs only.
Facts bank: add the head-IRQ/beam-detect entry and the coolant-ADC
offset entry; point the SDIO CRC note at the closed watch record.
Next work: trim items 6-10 to the open work with facts-bank citations,
remove the stale bench-page sentence from item 3, and retitle item 10
to the second-machine re-measure (the sensor-line scope work is
dropped by decision). Docs only, no catalog consequence.
Load/unload under DEBUG_MUTEXES (three clean cycles) and the forced
-EPROBE_DEFER unwind both passed on the debug-kernel image, no lock
splat, machine recovered (CAMPAIGN-LOG has the run). BRINGUP: the item
closes, items 4 and up move down one.
kas/forgefirm-glowforge-debug.yml builds one dev image on the debug
kernel (FORGEFIRM_KERNEL_DEBUG=1, tagged dev-debug) beside the closing
release and dev images; the debug options never touch either.
scripts/bench/debug_kernel_drills.py runs the two drills (three
load/unload cycles under DEBUG_MUTEXES, a forced -EPROBE_DEFER unwind),
each read against dmesg for lock splats, refusing on a non-debug kernel
or a non-idle machine; it is registered as a board bench tool. BRINGUP
item 3 names the mechanism and stays remaining work (run it on the
closing burn); the site's Build page documents the variant.
A head reset (its own 0xc9<-0x5a register) made the present head NAK
through its reboot; the witness reads errored (K-11 propagation) with no
spoofed positive, and the head recovered on a driver rebind
(CAMPAIGN-LOG has the drill). BRINGUP: the last physical-evidence
negative closes, items 4 and up move down one.
A busy capture node made the real head-image path fail with the measure
laser armed; the laser ended at 0 and the camera engine recovered
(CAMPAIGN-LOG has the drill). The STATE_FAULT-recovery note leaves the
item by operator decision. What remains is the K-11 case, one bench
slot.
