ScottW514 674cd1903c forgetest: take the kernel-counter reference only when the machine is at rest
Bench (image 20260817124714): motion.lid-cancel-home FAILED on a machine that
did the right thing twice. Both phases logged the cancel, the reset banner and
"returned to the job start" with grbl drift 0.000, and the counters ended at
the true rest position - but the hold phase's REFERENCE was 2.87 mm off, so the
comparison measured a transient.

The reference was sampled straight after the jogs that close the running phase,
and those wait on grblHAL's Idle. grblHAL is Idle when its planner is empty; the
kernel is still playing the stream depth and the decel tail behind that. A
counter read in that window records a position the head is only passing through
- and the resulting drift reads exactly like the failure this check exists to
catch, a move counted by grbl but never played by the machine.

So the check stays as strict as it is (it is the one that caught the stranded
ring on 2026-08-17): what changes is where the reference comes from. kernel_start()
waits for the MACHINE to be idle - the helper the motion tests already end on -
before reading the counters, and every reference capture in the lid, interlock
and live cancel tests goes through it.

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, 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.
