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.
- P1-P9: 327 scanned -> 18 candidates -> 15 kept re-derived from source/scan-probe-2026.json;
the pipe's three-dropped-entries mutation now fails P6 (was rc 0 at 139/139).
- B7-B10: claim_role graded against roles-expected.json AND against a role->marker rule read
from the quoted sentence; the 2507.02001v1 relabel now fails B8 and B10 (was rc 0 at 169/169).
- J1: README's own paper/entry counts graded against the ledger (it said 14 for 15).
- run_verdict.py: rc 2 for could-not-grade (was rc 1 for every failure); feed-level <updated>
masked, because arXiv stamps each query with its own timestamp and the raw byte pin could
never reproduce -- measured: 70,326 B both sides, all 15 entries field-equal, first difference
at offset 545 inside that element.
- mutation_battery.py: scratch from --scratch/TMPDIR and removed on exit (was a hard-coded
/root/.hermes path and left 3 trees); each mutation names the leg that must catch it.
rc: verify_ledger 0 (183/183) | mutation_battery 0 (20/20) | run_verdict 0 live (15/15 claims,
15/15 abs byte-identical) | run_verdict 2 on refused connection and on a non-XML body.
Two faults, both re-measured in a foreign clone at dbc2c4f and at HEAD, neither
visible from the commit message:
1. test_trie.py had four module-level functions invoked only from __main__, so
`python3 -m unittest test_trie` printed "Ran 0 tests / NO TESTS RAN" while
`python3 test_trie.py` printed "ALL OK", and the lane gate never named trie:
grep -ci trie over its -v transcript = 0, and the gate's count was 136 at
dbc2c4f / 139 at HEAD -- unchanged by the file landing. The four cells are now
nine unittest.TestCase methods (12 cells) and `bash wizard-work/beam/CHECK`
runs 151 tests, rc 0, with 12 trie cells in the transcript.
2. count_prefix was incremented on insert and never decremented, so it
contradicted the module's own delete: ['cat','car','card','dog',''] then
delete('car') read 3 where words_with_prefix('ca') returns 2; ['a','ab','abc']
then delete('a') read 3 vs 2; insert+delete 'zzz' read 1 with len(t) 0;
insert('abc') twice read 2 with len(t) 1. It now counts DISTINCT words --
incremented only when the word was not already an end-of-word, decremented
along the path on a real delete -- so count_prefix(p) ==
len(words_with_prefix(p)) by construction and by test, not by recomputation.
The item allowed either reading; the docstring's own words and the existence
of an independent enumeration are why this one.
Cells and controls (scratch/q70/, harness q70_mutants.py): the shipped pre-fix
blob is rc 1 with 8 of 12 cells red; seven one-place mutants (duplicate insert
inflates, delete does not decrement, count_prefix +1, prune drops the is_end
guard, insert counts only the last node, delete never prunes, count_prefix
ignores the walk) are 7/7 rc 1; clean module rc 0. Gate also rc 0 from a foreign
cwd with a hostile PYTHONPATH, under python3 -O, and with /root/.hermes masked
by tmpfs (0 entries); rc 1 with the in-tree module deleted.
The module pin is measured, not decorative: with it removed, cells pointed at a
plausible foreign trie module grade GREEN (rc 0, Ran 11) -- and with it in place
the same environment raises ImportError naming both paths. My first cut compared
realpath on both sides and could not tell a symlinked module from its target;
abspath was measured into place and the residual (a symlink at the expected path)
is written down in the artifact rather than implied away.
Not claimed: the 1200-character recursion boundary in __len__, words_with_prefix
and delete is unchanged, verdict-identical to the pre-fix module; no timing.
Files: 2 changed (229 79), plus wizard-work/volt/q70-2026-10-26.md. No host
paths added (git grep -c -e /root/troupe-standup -e /root/.hermes = 0 on all
three). Nothing from inbox/ quoted. Beam's files edited under Q70's own "anyone
may take it".
CHECK rc 0 at this commit: `bash wizard-work/beam/CHECK` -> Ran 151 tests, OK.
