On the bench the head accelerometer's sysfs read lands two or three samples in a one-second jog leg, and two samples on the constant-velocity stretch read near idle with the head in full flight: the accelerometer sees the ramps, not the travel. The first unattended queue on dev image 20260822204234 failed motion.jog-roundtrip on that (2 of 8 legs judged) with the head plainly moving where a ramp was caught (p2p 3019, 1330, 1698, 1663). The verdict is now over the sequence: p2p across all the legs at or above the liveness threshold, and motion on at least two distinct legs (one jolt is not a gantry moving on every jog); the sampler must have landed samples at all. Rerun: p2p 2897 over 17 samples, motion on 3 legs, PASS; the whole unattended queue passed (15, then 9 re-required by the module hash) on that image. camera.snapshot's PASS line names the half-res frame it compared (the full-res size had been printed in its place). AccelSampler gets host tests over a fake iio tree.
forgetest - the ForgeFIRM release acceptance tool
The daemon behind http://<machine>:8090/ on the dev image: runs the
acceptance catalog against the machine, keeps the append-only result log,
decides which results still apply to the image that is running, exports
the release artifact scripts/release.sh gates on, and serves the bench
diagnostics page. The contract - catalog, campaigns, fingerprints,
inheritance, the gate, the coverage rule - is
docs/ACCEPTANCE.md.
Run the host tests
cd forgetest
python3 -m unittest discover -s tests -v
Run the daemon on a workstation (against a mock or a manifest file)
FORGETEST_DATA=/tmp/ft FORGETEST_MANIFEST=../tree-manifest.json \
FORGECTRL_URL=http://<machine>:8080 python3 -m forgetest --port 8090
scripts/manifest-from-tree.py produces tree-manifest.json from the recipe
pins; the coverage lint is python3 -m forgetest.coverage --manifest ....

Adding a test
Register it in the subsystem module under forgetest/suite/ with
@test(...): id subsystem.name, kind, hardware, mode (the controller
mode the test needs; the runner switches to it first), covers,
requires, always, steps. The body gets a Context (log, check, fail,
prompt, confirm, instruct, sleep, evidence, forgectrl, sysfs,
grbl, takeover). Return normally for PASS, raise runner.Failed for
FAIL. Then run the unit tests and the coverage lint.
