laser.emission-witness required the hardware button latch clear in every sample the engine reported armed, and, after a first fix, in every sample up to the last nonzero emission count. Both windows were drawn from lagging signals: the engine's armed flag follows the controller's next report, and the emission counter latches once per second and reads nonzero about two seconds past the relock. Both reached into the tail where the job-end relock sets the button latch by design, and the rule refused three clean runs on image 20260902144848 (all four sides burned; the trail shows the latch clear from the press to the relock, emission through the fourth side, HV_ENABLE's dip in the dwell and its return). The rule now uses the window the hardware defines: from the first emission, in every sample whose readback word shows the laser latch unlocked, the button-latch bit of that same word must be clear. That spans the kernel-run gap of the dwell and ends at the relock, and no lagging flag can misplace it. dwell_gap() is a pure function; tests/test_laser_dwell.py holds the relocked tail, a set inside the gap, and a trail without emission. The recorded trail of the third run replays to a pass (47 unlocked samples, none set). The live runs keep a per-sample trail in the evidence (TRAIL_FIELDS: the readback word, the switches, the lock flag, the controller's state and messages), so a run's timeline can be read back without a rerun. A fourth run then errored on a name the refactor had removed and one later check still used; py_compile does not catch it and a live drill never executes on the host, so the CI job now fails on any undefined name in the harness (pyflakes). Catalog consequence: the laser implementation hashes move.
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>: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.
