The cooling engine publishes its state once a tick (1 Hz). A /cool/status
read inside the tick after a run ended still shows the run: while a
diagnostic owns the hardware every tick publishes phase "diag" with the
hold set, and a fail tier's hold stands until the tick that ends its
session. The baseline took one read, and by its rule an arm or a hold is
the run's doing, so a test that finished inside that second failed its
hand-back on a hold the engine's next tick cleared.
Seen on the bench reference twice. cooling.aa-offset-calibrate in campaign
c-20260919215024-c402: the diagnostic reported done at 22:07:14 with its
offset measured (15.7 counts, spread 0.7), and the hand-back at 22:07:15
read "cool=diag/armed=False/hold=True ... -> waited" and failed the run;
the test had passed on five images before, the last one earlier the same
day. cooling.fail-tier-stop in c-20260919202934-3d3a, the same way on the
crash fault's hold (0ceb4ab made that test wait for its own fault; this is
the general case).
The cooling check moves into Baseline._cool_side. An arm or a hold is read
again for up to COOL_PUBLISH_S (2.5 s: two ticks and a margin) before it is
called the run's doing. One the next tick cleared is logged as the engine's
last word on the run and judged on what the engine reads then: idle is
clean, a cooldown phase is waited out as the engine's own post-job work. A
hold a run did leave stands for a job that is never coming back, so it is
still there after the tick and is recorded, stood down and failed exactly
as before; a hold that clears only later is still a leftover ("waited").
Proven: tests/test_baseline.py CoolPublishTests - a diagnostic's hold the
next tick clears, a fail tier's hold clearing into the smoke phase, a hold
that outlives the tick (recorded, machine stood down), a hold that clears
only later (recorded as waited), an idle engine and a silent daemon; the
baseline, queue, operator, mode, responsiveness and server host tests
pass under Linux. baseline.py is not a suite module, so no test's
fingerprint moves with 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
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.
