Setting the release number was a platform change. FORGEFIRM_RELEASE sat in forgefirm-image.bb, the recipe hashes as content of meta-forgefirm, and a change to the content of a layer invalidates every acceptance result. So a version bump threw away the campaign that was meant to authorize that very release, and the number therefore had to be decided before the image the campaign ran on. Nothing said so: the release-flow page went straight from the kas configuration to the artifact and the pipeline, while the gate quietly required the recipe value, the rootfs stamp, the archive's meta-version and the tag to agree. v0.0.1 was cut on a tree whose number happened to be right; the next one would have cost a second campaign to discover the rule. The number moves to forgefirm-release.inc, which carries it and nothing else, and the manifest leaves that file out of the layer content hash exactly as it leaves out the component pin files (FORGEFIRM_MANIFEST_VERSION_SUFFIX, and the same list in scripts/manifest-from-tree.py, which computes the identity on a workstation and must agree byte for byte). release.sh reads the number from the new file. The version is metadata, not platform content, and this only makes the manifest say what it already meant: the version string was already outside the identity hash, and it was the file carrying it that defeated that. Nothing is weakened. release.sh still requires the number to equal the rootfs stamp, the .fw meta-version and the release tag, and image.health still compares the stamp on the running machine with the manifest's. Proven: the tree manifest is byte-identical across a bump from 0.0.1 to 0.0.2 (identity a64e51b8e5ecca0af683d4f0 either way, the meta-forgefirm layer hash unchanged), where before the two differed. bitbake resolves FORGEFIRM_RELEASE=0.0.1 and FORGEFIRM_VERSION_STRING=v0.0.1 for the release image through the new require, and the dev image still overrides the string with its build timestamp.
OpenGlow / ForgeFIRM firmware for Glowforge
BETA
ForgeFIRM is in beta. Every release below 0.1.0 is a beta release. Expect problems, 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.
