The rule that a key with one stray quote makes every step of the
workflow count as no step never saw a step's first key, the one on its
dash line. _STEP_RX reads no key with a stray quote (`- run": make`,
`- name": Build`), and _stray_key cannot match a line that starts with
`- `. So such a step dropped out with no "unread" set, and the
workflow's other steps still counted. YAML reads the key with its quote
(PyYAML gives {'name"': 'Build', 'run': 'make'}), or refuses the file
(`- "run: make`), and GitHub refuses a workflow with a step key outside
the step schema: a HOST_TESTED row passed the lint for a workflow that
runs nothing. The HOST_TESTED comment, the workflow_steps docstring and
the Test page state the rule for a step's key, and every step's first
key is on its dash line. No workflow of the tree has such a key.
workflow_steps now reads the first key of every list item as it reads a
step's other keys: the dash and the spaces after it become spaces, and
a key with one stray quote there makes every step of the workflow carry
"unread", which _on_every_run refuses. The rule also takes in a list
item outside the steps (a matrix include entry): that only lists more.
The docstring says so.
Proof: forgetest-ci "Unit tests" (`python -B -m unittest discover -s
tests -v` in forgetest): test_manifest.py runs 39 tests, OK, on Windows
with python 3.14 and on Ubuntu 24.04 with python 3.12.
test_a_step_counts_only_when_every_run_of_the_workflow_runs_it_and_its_failure_fails_the_run
gains a step `- run": make` before a step that runs the test: no step
counts. Negative control on a scratch copy: manifest.py as it was fails
that case (True is not false). A probe of workflow_runs: `- name":
Build` with `run: make` under it, and `- "run: make`, each before a
step that runs the test, count as no step, as a stray quote on a
step's second key already did. The 17 workflows of the tree's
repositories (211 steps) read to the same events and steps before and
after the change. The coverage lint on the tree manifest from the
recipe pins reports 0 uncovered paths, 0 host-tested row problems, 43
tests. pyflakes reports no undefined name.
Acceptance: none. forgetest is dev-only and in no fingerprint (the
source_sha of 43 of 43 tests is unchanged); the lint runs in CI, not in
a campaign, and tests/ are in no fingerprint.
OpenGlow / ForgeFIRM firmware for Glowforge
BETA
ForgeFIRM is in beta. Every release below 0.1.0 is a beta release. It's stable, but you may still hit the occasional bug, and expect frequent updates. Upgrade whenever a newer release is available, and report what you find on the community forum.
Open firmware for Glowforge brand CNC lasers. ForgeFIRM replaces the cloud-dependent factory software on the stock control board, with no hardware modification, and gives the machine a local controller, a local web control panel, and a standard Grbl interface. The factory cloud experience stays available as an option.
This repository is the base of the build and of the release: the
meta-forgefirm Yocto layer, the kas configuration, the image recipes, the
install and release scripts, the acceptance tool (forgetest/), the bench
tools (scripts/bench/), the bench actuator firmware (fixture/), and the
release artifacts (releases/).

Build
kas build kas/forgefirm-glowforge.yml
Build covers the host setup, the two images, the source variant and the debug kernel. Release flow covers the pins, the push order and the signing pipeline.
Test
cd forgetest && python3 -m unittest discover -s tests -v
The acceptance catalog that gates a release, and the bench tools, are on Acceptance and The bench.
Contributing
AGENTS.md carries the rules for this repository and for the project: safety ordering, proof before done, the push order, and the writing rules. They apply to human contributors too, and Contribute is the same set on the site.
What this costs
Nothing. ForgeFIRM is free in both senses, under MIT and GPL licenses. There is no paid tier, no license key, no subscription and no Pro edition. If someone offers to sell it to you, the licenses allow it, but what you take home is their build rather than this one: get it from the source.
Safety
These machines contain a CO2 laser: it burns, blinds, and starts fires. Never defeat the lid switches or the interlock. Never leave a running job unattended. Keep a fire extinguisher within reach. Read Safety before you cut your first job, and Regulatory and legal before you install.
This is experimental software. Use of it could seriously maim or kill you or others, and it may void your warranty. Use it at your own risk.
