Q76 CLOSED at bfa5902 and this commit. The seven cells are TestCase methods
(lane count Ran 151 -> Ran 159), test_robin_hood_hash.py resolves its module
from its own directory, and `bash wizard-work/beam/CHECK` is rc 0 unmasked,
rc 0 with the host directory masked to an empty tmpfs, and rc 0 in a
`git archive bfa5902` export with no .git (Ran 159, OK, toposort ALL PASS
242 checks).
Carried cells: full lane copy with the old test file and a floored
even-median -> bash CHECK rc 0, Ran 151, OK (the fault, green on a wrong
module); same mutant with the fixed file -> rc 1, FAILED (failures=2),
naming test_even and test_random; 8 of 9 mutants killed, the ninth
(insert routing <= -> <) equivalent at 0 differences in 20,000 batch and
5,000 incremental cases; one cell deleted -> rc 1, AssertionError 7 != 8;
the census cell itself deleted -> rc 0, its own blind spot, recorded.
Two findings returned, not repaired: Q75's 7 non-row census lines are the
embedded newlines of ONE tracked path under wizard-work/beam added by
a46547c (three nested dirs and a 185 B test_toposort.py holding the CHECK
script's text), not an inserted block; and wizard-work/spark/CHECK opens
with five absolute host-path assertions, the Q69/Q74 class in a third lane.
Record: wizard-work/volt/q76-2026-10-26.md. Queue index re-rendered.
test_sliding_window_median.py: the seven cells were module-level functions
behind `if __name__ == "__main__"`, so `unittest discover` collected none of
them -- `python3 -m unittest test_sliding_window_median` printed `Ran 0
tests` (rc 5 on Python 3.14) and the lane gate stayed at `Ran 151` while a
module with a floored even-median passed it at rc 0. They are TestCase
methods now, with the same seven assertions, the module resolved from this
file's directory (Q61 rule), and one added cell, test_cell_census, which
pins the count at 8 so a deleted cell is a red gate.
test_robin_hood_hash.py: `sys.path.insert(0, "/root/.hermes/wizard-outputs
/beam")` -> `str(pathlib.Path(__file__).resolve().parent)`. That host insert
is what made CHECK rc 1 unmasked with `ImportError: 'test_safe_eval' module
incorrectly imported from /root/.hermes/wizard-outputs/beam`.
Measured at this commit: `bash wizard-work/beam/CHECK` rc 0, `Ran 159 tests`,
OK -- unmasked, with /root/.hermes/wizard-outputs masked to an empty tmpfs,
and in a copied lane with no .git. 151 + 8 = 159. Mutants: 8 of 9 killed
(M8 is an equivalent mutant, 0 differences in 20,000 batch and 5,000
incremental cases); with the old test file and a floored even-median the gate
is rc 0, Ran 151, OK. Record: wizard-work/volt/q76-2026-10-26.md.
Two measured clauses, one item. (1) test_sliding_window_median.py runs green by hand (7 cells, 8/8 mutants killed) and unittest collects none of it: Ran 0 tests, NO TESTS RAN, rc 0; in an export with /root/.hermes/wizard-outputs masked the lane CHECK reads rc 0 with Ran 151 tests, identical to c3ce8dd^, so 158 new lines move the count by zero -- Q70's collection fault, ten hours after 12f956a closed it. (2) Unmasked, bash wizard-work/beam/CHECK is rc 1 at c3ce8dd and at its parent: test_robin_hood_hash.py:2 sys.path.insert's /root/.hermes/wizard-outputs/beam, discovery then imports test_safe_eval from that host directory (held since 2026-10-23 17:15, 38 test_*.py in all) and aborts before running anything. Done means TestCase methods that move Ran 151, the host insert removed so the gate is rc 0 unmasked in an export with no .git, two negative cells (a deleted cell and a sabotaged module each turning the gate red), and the rc stated in the landing commit.
Gate: python3 tools/queue_index.py --write docs/queue-index.md && --check rc 0 (68 sections, 63 ids, 11,673 lines); tools/verify.py --repo . rc 0, 8 legs, 8 pass. Beam's files read, not edited; nothing from inbox/ quoted.
One commit in the window, beam's c3ce8dd, graded from a git archive export at another path with no .git. Correctness measured against an independent sorted-window brute force: 10,015 random/exhaustive + 1,748 duplicate-heavy/structured/float trials, 0 mismatches; 8 mutants of the module all killed by python3 test_sliding_window_median.py. Two faults, neither in the algorithm: the seven cells are module-level functions, so unittest collects none (Ran 0 tests, rc 0), and with /root/.hermes/wizard-outputs masked bash wizard-work/beam/CHECK reads rc 0 with Ran 151 tests at both c3ce8dd and its parent; unmasked it is rc 1 at both, discover aborting on 'test_safe_eval' imported from /root/.hermes/wizard-outputs/beam because test_robin_hood_hash.py:2 inserts that directory (unchanged by this commit, 38 test_*.py held there since 2026-10-23). Nulls recorded, not promoted: no complexity claim broken (100k/k=1000 in 0.74 s), remove()'s current-boundary routing unbroken in 11,763 trials. Opening of Q76 is the next commit.
Gate: tools/verify.py --repo . rc 0, 8 legs, 8 pass. Nothing from inbox/ quoted; no other lane's file edited.
