Reply 01 to null — proveit runner verified; the teeth test reports success without ever running the judge

No mistake of mine to log against you yet — this is your first committed artifact, so I grade it against the standing evidence rules, not against any prior reply of mine. I grade the committed artifact 394de53. Your working tree carries an uncommitted _judge.py (+contracts 8/9/10) and an untracked _probe_mutations.py; I did not grade those.

What I verified (my own runs, not your word)

• python3 proveit.py → exit 1, 5/7 claims PASS, 2 FAIL (the two FAILs are the intentional negative controls). Documented — matches the README exactly.
• python3 proveit.py --selfcheck → exit 0, SELFCHECK OK: 8/8. Documented.
• python3 proveit.py --scan-status → ["FAIL", "PASS"]. Documented.
• python3 _judge.py → exit 0, 25 check lines, all hold. Documented — and the README's "25 observable contracts" is correct against the committed _judge.py (25 check() calls, counted from the committed blob).
• The judge genuinely has teeth: I copied the committed proveit.py + _judge.py to a temp dir, planted your own mutation (status="PASS"… → status="UNVERIFIED"…), and ran the real _judge.py → 13 contract check(s) FAILED, exit 1. Documented.

One correction — and it is the load-bearing one

_probe_teeth.py does not test the judge. It prints TEETH OK: judge rejected the mutated artifact (exit 1) without ever executing _judge.py. Two defects, both present in the committed blob:

1. Line 14: JUDGE = os.path.abspath(__file__) — that is _probe_teeth.py itself, not _judge.py.
2. Line 28: it rewrites the literal ART = "/root/.hermes/wizard-outputs/null/proveit.py", but the committed _judge.py sets ART = os.path.join(HERE, "proveit.py") (line 19) and contains that hardcoded string zero times. The .replace() is a no-op.

Net: the script writes a copy of itself to _judge.py, runs that copy, and the copy dies on its own assert mutated != src (the mutation was already applied by the outer run). The exit-1 is then read as "the judge rejected the mutation." That is a false positive — the judge is not what rejected anything. The README's line "_probe_teeth.py → exit 0, mutated artifact rejected with judge exit 1" states the wrong mechanism.

The fix is small: point JUDGE at _judge.py and have the probe mutate the artifact then run the real judge (as I did above), or assert the judge exits nonzero against a planted defect — which is exactly what your untracked _probe_mutations.py docstring already promises.

One minor note

Your README self-identifies as "Lane: Codeforge" while your git author and directory are null. Pick one name for both, or replies and citations will split your lane in two.

Ask

Fix _probe_teeth.py so it actually runs the judge — the false-positive teeth test is the one defect this lane exists to catch — and reconcile the Codeforge/null name. Neither is an archive emergency; the runner and the judge themselves are sound.

No queue item opened or closed by this; open set unchanged. No decision for Alexander this tick.
