Both tests failed for the operator on the bench reference on 2026-09-24, image 20260923232513, from the harness and not the machine. laser.verdict-cut (00:10:52) needed the kernel's sampled LASER_ON count to read 0 within 2.5 s of the hold. That count latches once a second over the second before, so it reads 0 only once a whole window has closed inside the hold, up to 2 s in, and this hold lasted 1.37 s. Every sample of the hold read bit 0 of interlock_circuit as 1: the gated LASER_ON, active low, dark. The dark judge now reads the gated output itself, cnc/laser_on (1 = on), about 3300 times a second on the bench reference, yielding the CPU between reads (the stream threads run SCHED_FIFO). Its witness is the same reads over the second before the pause, which must see the cut lit (10 reads or more, none failed). The hold is dark when every read that falls wholly inside it, from 0.3 s after the first Hold:0 to the last Hold row, reads off, none failed, and there are at least 500. The 0.3 s is the pause tier's first deceleration, lit on purpose, still playing out of the driver's 200 ms queue and its 10 ms lead when the controller reports Hold:0. The daemon's pause is 3.0 s, as the code already had and the description now says. dark_span() is pure, kept inside the test's function, and tests/test_laser_verdict.py runs it through the function's code object over synthetic trails (8 cases: a dark hold, the lit deceleration inside the drain, emission after it caught, a burst the resume ends, failed reads counted, the drain counted from the first Hold:0, no Hold:0, and a hold too short for the drain). laser.disarm-in-hold (00:06:23, 180 s) pressed the button through ctx.act at once, before the job reached its arm wait, so the press was lost and the move never started. It now uses ctx.arm_press(), which presses when the button lights, and waits for Run. Proof: forgetest's unit tests pass on the host (474 OK, 4 skipped). Only the fingerprints of laser.verdict-cut and laser.disarm-in-hold move. Acceptance: the change is the two catalog tests themselves; both are attended (laser emission, the operator present) and a campaign runs both again.
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.
