ScottW514 8d16b93e86 forgetest: the shared judges and a test's own imports reach the hash the gate reads
The sibling walk read the top-level statements of a module alone. Five
tests import their judging helpers inside their own functions, so that
no other test of the module moves with them: cloud.mode-switch
(homeoff.py: judge_whole_motions, camera_home_return),
cooling.flow-under-load and cooling.fail-tier-stop (laser.py's sample
and run_and_sample, motion.py's log readers), forgectrl.auth (setup.py's
request and decode) and motion.release (setup_dark.py's run_check).
None of those helpers was in the hash of its test, and homeoff.py was
in no hash at all: an edit to judge_whole_motions moved 0 of 43 tests,
and an edit to laser.sample moved the three laser.* tests and neither
cooling test, so an inherited PASS survived a change to its own judge.
The guard that every package module a suite module imports is a listed
judge read the top level alone too, and no unit test held the
production path: Test.source_sha, which the fingerprint, the campaign
and the gate read, could drop the shared judges with CI green.

implementation_sha now adds to the hash of a test the suite modules its
own @test function imports, at any depth, and what they import in turn;
no other test of the module takes them. The shared text of a module
gives the modules it imports at any depth too: a helper that imports
inside its body brings that module into every test of the module, as
the helper itself does. _test_defs finds the @test functions of a
module for module_parts and for both walks. The guard walks the whole
tree of each suite module, so a package import inside a function or a
block is held to the list as well. test_a_shared_judge_edit_moves_every_test
holds the production path on a suite test: its source_sha equals
implementation_sha with SHARED_JUDGES and differs from it with none.

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, with
test_a_sibling_imported_inside_a_function_moves_the_tests_that_run_it
(a judge imported in the body of one test moves that test and not the
other; imported in the body of a helper, it moves both), the
source_sha assertions, and the guard on the whole tree; test_artifact.py,
test_campaign.py, test_redact.py and test_responsiveness.py pass.
Negative controls on scratch copies: implementation_sha's default
taking no judges fails the source_sha assertion, and so does
Test.source_sha passing judges=(); the new case fails against
catalog.py as it was, and against a shared-text walk of top-level
statements alone; a `from .. import server` inside a function of
suite/forgectrl.py, or in a try block at its top level, fails the
guard, and the function-local one passes the guard that reads the top
level alone. On the real catalog: an edit to judge_whole_motions moves
cloud.mode-switch alone (0 tests before); an edit to laser.sample moves
the three laser.* tests and both cooling tests (the three alone
before); an edit to run_check moves the six setup.* tests and
motion.release (the six alone before); an edit to setup.request moves
forgectrl.auth and motion.release (motion.release through setup_dark.py,
which imports setup.py) beside the 8 it moved before; an edit to
hw.sysfs_int
moves 43 of 43, as before. 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: cloud.mode-switch, cooling.flow-under-load,
cooling.fail-tier-stop, forgectrl.auth and motion.release: the
implementation hash of each moves once, its own imports joining it; the
other 38 do not move (source_sha compared before and after). Against
the campaign this series already needs, that adds no run: 850498f moved
all 43 once. 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.
