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.
