The freeze is the rule that keeps a package off the core while a job can fire, and it had a host test against a stand-in forgectrl and one drill by hand. This is its test on the machine, against the real engine. The reference package runs, its heartbeat advancing twice a second. cloud.dark-print's own job and body (a 30 s square at S0, the fixture's press, the latch locked at the button, unlocked for the run, locked after) open a real armed window over it. A sampler reads five times a second: the engine's armed flag (GET /cool/status), the group's frozen state as the kernel reports it (cgroup.events), the heartbeat, the service's pid, and the latch. The test asks for a window of 10 s or more; frozen in every sample from 2 s in to the close, with the heartbeat still; the first frozen sample no later than the first unlocked-latch sample, so the freeze is in place before the run; thawed, with the heartbeat moving again, 3 s after the close; and one process throughout. exthost.service's put-back and its as-found checks became _put_back() and _as_found(), shared by both tests. exthost's top-level imports pulled the setup suite (and now the cloud suite) in ahead of it and reordered the catalog, so exthost is imported last: image, kernel, forgectrl, setup, logs, motion, cooling, laser, camera, update, cloud, exthost; 106 tests. Proven. The unit suite: 451 tests, 0 undefined names. On the bench reference, image 20260920211625 with the cross-built forgectrl and host from /tmp, the coolant taken from 27.2 to 25.4 C with an M8 session first (the cloud client starts no print above 27): exthost.armed-freeze PASS, the window open 37.5 s, the group frozen 0.42 s after it opened and 4.97 s before the latch unlocked for the run, frozen in all 172 samples from 2 s in to the close with the heartbeat still, thawed 0.62 s after the close. With the host suspended (SIGSTOP) across the window, so that nobody freezes anything, it FAILS: not frozen in 177 of 177 samples. exthost.service PASS again after the refactor (a killed host's service gone in 0.05 s, the host back and the service running after 5.6 s). The bench was left as found. Acceptance. exthost.armed-freeze is new: kind operator (the fixture presses), takeover; it covers forgeext's src/super.*, src/run.*, src/machine.*, src/cgroup.*, and forgectrl's src/cool.*, and requires exthost.service and cloud.dark-print.
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
the Acceptance page of the documentation site.
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> 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.
