The coverage lint counts a step of a HOST_TESTED row's workflow only
in a job whose `needs:` are met on every run, and _needs read two
valid forms of the key as an empty list, which _needs_run takes as
needs met. A block list whose items sit at the key's own indentation
(`needs:` over `- build`) ended at its first item, which the loop took
for the next key. A flow list continued on the lines under the key
(`needs: [` over `build` over `]`) ended at the key's line, with no
item, and one split after a comma (`needs: [lint,` over `build]`)
kept the first line's names and dropped the rest. So a job that
needed a conditional job, written either way, counted as running on
every run, and a host test behind a conditional build kept its row
green and its paths covered. No workflow a row names writes its
`needs:` in these forms.
_needs now takes a `- ` item at the key's own indentation as part of
the block list, and ends the list at a key at the key's indentation
or less; items at two indentations are a form it does not read. A
flow list whose `]` is not on the key's line is joined with the lines
under it up to the `]`: a key, or a line at the key's indentation
that is not the `]`, before it ends the join as a form not read.
Every form not read gives None, a name no job has, so the need is
never met: fail closed. An empty `needs:` (`[]`, or nothing under the
key) gives None too: GitHub refuses an empty needs, and a job that
names one does not run. The docstring names every form that fails
closed, so its claim is true of each.
Proof: forgetest-ci "Unit tests" (`python -B -m unittest discover -s
tests -v` in forgetest): test_manifest.py runs 41 tests, OK, on
Ubuntu 24.04 with python 3.12, in a private PID namespace.
test_a_job_runs_only_when_every_job_it_needs_runs gains the block
list at the key's indentation and the flow list across three lines
among the forms that run the test with the needed job unconditional
and do not with it under `if: false` or `if: github.event_name ==
'push'`; a flow list split after its comma in the chain of three,
which runs the test, and does not with the second-line job under
`if: false`; and, each failing closed with the needed job
unconditional, `needs: []`, a bare `needs:`, a flow list a key
interrupts before its `]`, and items at two indentations. Through
host_row_problems, a workflow on `[push]` whose test job needs, in a
block list at the key's indentation, a build job under `if: false`
is listed as "does not run it". Control: the parent, 8fc411f, with
the new test file fails the case (failures=1) at the block list at
the key's indentation, and run one by one against the parent's
manifest.py, each of the seven new forms reads as run and the row
passes. The coverage lint on the tree manifest from the recipe pins,
with meta-openglow at 1e163bd on scarthgap, reports 0 uncovered
paths, 0 empty entries, 0 host-tested row problems, 43 tests.
pyflakes reports nothing.
Acceptance: none. forgetest is dev-only and in no fingerprint; 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.
