The coverage lint counts a HOST_TESTED row's workflow on a push or a
pull_request with no filter under it, and it read a `types:` under
the pull_request as nothing. A pull_request under `types:` runs on
the activity types it names and no other, so a workflow on
`pull_request: types: [closed]` never runs on a pull request's open
or its new commits, and a row on it counted as running on every
change, with the host test behind it keeping its paths covered. No
workflow a row names writes a `types:`.
workflow_filters reads a `types:` key at the pull_request's own level
as a filter, by name, as it reads a `paths:`: the lint reads no type,
so any `types:` is one, fail closed. A `types:` is read under the
pull_request alone: a push has none, and the lint counts no other
event. host_row_problems lists a workflow whose pull_request carries
one and whose push carries a filter, or is absent, as "every push or
pull_request in its own on: carries a filter (pull_request: types)";
a push with no filter beside it keeps the workflow counting. The
HOST_TESTED comment and the docstrings name the types filter.
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_push_or_pull_request_under_a_filter_runs_on_not_every_change
gains: workflow_filters reads a `types:` under the pull_request with
a plain push beside it as the pull_request's filter alone; a
`types:` block list with a `paths-ignore:` after it as both; and a
`types:` under a push as none. Through host_row_problems, a plain
push with a pull_request under `types: [closed]` passes, and the
pull_request under `types: [closed]` alone is listed with
"pull_request: types". Control: the parent, 9e7b065, with the new
test file fails the case (failures=1) at the first `types:`, and
against the parent's manifest.py, workflow_filters reads both
`types:` fixtures as no filter and host_row_problems passes both
rows. 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.
