The module had no cell in any gate, and read two ways: its docstring promised
ValueError for 'no duplicate present' while its self-test said it does not
promise detection at all. Measured at 95e4962: every array of length n+1 over
1..n for n=1..4 (1,114 inputs) returns a value occurring at least twice, 0
ValueErrors, and the no-duplicate guard's raise never fires (its condition is
evaluated on all 1,114 and is never true). The nearest no-duplicate shape,
[1,2,3,4], is refused by the RANGE gate: 'value 4 out of range [1, 3]'.
- find_duplicate.py: docstring edge case states the pigeonhole argument and
that the branch is unreachable; the 'exactly one value appearing twice' claim
(contradicted by the file's own [2,2,2] case) corrected; the guard moved into
_no_duplicate_guard() with the reason it is kept -- with phase 2's loop
deleted it fires on 272 of the same 1,114 arrays, first [1,2,1]; self-test
paragraph replaced and it now asserts the range-gate message.
- test_find_duplicate.py: 12 cells / 1,133 subtests, including the exhaustive
domain (pinned at 1,114 and 'the return occurs twice') and a dead-branch cell
that traces the module and asserts the AST-located no-duplicate raise is the
only unexecuted statement.
- Falsified: 9 named mutants, 9 killed, control green; beam CHECK 446 passed /
2,007 subtests -> 458 / 3,140.
WHY: test_acquire_blocks_and_returns took t0 after the drain, so the cell timed
only the part of the 0.05 s refill that happened after the scheduler returned to
it. Observed red in a loaded full-suite run at 7c36185:
'assert 0.03909331373870373 >= 0.04' -- 10.9 ms of untimed prefix. Deterministic
repro: pre-fix cell + 11 ms injected gap -> 0.03897/0.03912, rc 1.
FIX: t0 now precedes try_acquire(1.0), which is where the bucket sets _last, so
dt is >= 0.05 by construction (acquire cannot return before the refill origin is
1/rate old) and the 0.04 floor has ~10 ms of margin instead of 1 ms.
MEASURED: repo cell 9 passed; pre control rc 1 dt 0.03897-0.03912; post control
rc 0; same-gap in-process dt pre 0.039119 / post 0.050253; non-blocking-acquire
mutant rc 1 (2 failed: blocks + timeout cells); controls/post 15/15 green under
4-CPU saturation; bash wizard-work/beam/CHECK rc 0 twice, 423 passed / 2007
subtests.
CHECK: python3 /root/.hermes/wizard-outputs/volt/2026-10-28-q122/verify.py
wizard-work/beam/test_jsonl_validate.py (new, 25 tests) pins the module's own
docstring contract as process exit codes: 0 valid, 1 bad rows, 2 usage/IO/schema/
decode. wizard-work/beam/jsonl_validate.py repaired in three places:
- undecodable input (and schema) now returns 2 with an `input error:` line and
no summary line, instead of a UnicodeDecodeError traceback and rc 1;
- utf-8-sig on both files, so a leading BOM is stripped not graded as bad data;
- a required field present as null yields one error, not "missing required
field" plus "null not allowed".
Measured: the new test file against the shipped module (md5 f53b6288...) fails
6 of 25 (3 decode, 2 BOM, 1 null); against the repair, 25/25 pass. bash CHECK:
rc 0 with Ran 243 -> Ran 268; with the shipped module swapped back in, rc 1
FAILED (failures=6) -- the gate was rc 0 and blind before. No edit to CHECK:
the file is a unittest.TestCase, so the existing -p 'test_*.py' leg collects it.
The 242-checks line is toposort's import-time counter and does not move (Q105).
verify.py --repo . reads 8 legs, 6 pass, 2 fault (checkin, path-claims) here and
identically at the parent cd5f5c9. path_claim_check's tolerated NOT_ADDED row
for the new file reads CLEARED on this tree. Q105's 27 uncollected files / 131
tests remain open and untouched.
The eight test files Q98 leaves open (plus test_bfs.py, added at 7439cf0 with the
same lock) now resolve their module from pathlib.Path(__file__).resolve().parent
instead of /root/.hermes/wizard-outputs/<lane>.
tools/import_resolve_check.py --repo . at 7439cf0: 95 files, 9 faults, rc 1
after: 95 files, 0 faults, rc 0
Behaviour-preserving: every host copy the tests were reading is byte-identical
(md5sum) to the repo copy. Three absolute literals in spark/test_validator.py
that the static leg does not grade (load_json(...) argument strings at pre-fix
lines 12/16/25) are re-pointed too.
ledger/test_scratch_manifest.py was red before any edit (str ROOT vs
gen_manifest ROOT.iterdir), would have written the tracked
ledger/wizardwork-file-manifest.tsv once that was fixed (MANIFEST derived from
OUT at import time), and asserted nothing. It now re-points ROOT/OUT/MANIFEST,
guards MANIFEST inside a tempfile.mkdtemp(), and asserts the exact manifest row.
Non-vacuity: scratch/q98b/poison_probe.py copies each lane, runs the test from a
foreign cwd (rc 0), poisons the module inside the copy, and re-runs -- 8/8 go
rc 1, so none of them still reads the host.
Lane gates unchanged: beam CHECK rc 0, spark CHECK rc 0 (VERIFIED), ledger CHECK
rc 1 on both sides (commit-census drift, red at the parent commit too).
Q99's subject was a single tracked name holding seven newline bytes,
`wizard-work/beam/CHECK\ncontent">\n#!/bin/bash\n...`, added by accident at
`a46547c` (a shell-quoting accident, printf/heredoc output used as a pathspec),
218 bytes, blob `763936956721f3ba047d25b884f17862469482c3`.
Before this commit at `47532eb`: `git ls-files -z` yields 3,816 names and seven
of those bytes are `\n`, so a newline-splitting consumer reads 3,823 rows for
3,816 entries. The one path does not merely inflate the total, it impersonates
files: `git ls-tree -r -z --name-only HEAD | tr '\0' '\n'` prints it as eight
consecutive rows (lines 670-677 at `47532eb`), the first four of which are
`wizard-work/beam/CHECK`, `content">`, `#!/bin/bash` and
`# CHECK: verify all beam reliability primitives` -- four names a per-file census
or a per-file gate would try to open.
Content is not lost and nothing is being decided about it: the blob is
byte-for-byte `wizard-work/beam/CHECK` minus its final newline, verified against
`a46547c:wizard-work/beam/CHECK` and against HEAD's copy (`bad == good[:-1]`,
185 B vs 186 B, no differing offset), and the real CHECK is untouched. The blob
remains reachable from `a46547c`, so `git cat-file blob 7639369` still resolves
after this commit.
Guards run before the unlink: the worktree bytes were asserted equal to the blob
the index pinned, and that blob was asserted reachable from a ref.
After this commit: tracked 3,816 -> 3,815, names containing `\n` 1 -> 0,
newline-split rows 3,823 -> 3,815 (== entry count). An index-derived census keyed
on backslash-escaped names (`q99_census.py`, scratch) reads before=3816
after=3815, removed=1, added=0, changed=0 -- the removal is the whole delta, and
Q99's done-means ("a census run before and after differs only by that entry") is
met under a key that can express the entry at all.
Gate A/B on a scratch clone, committed there so HEAD moved: `tools/verify.py`
reads 5 pass / 3 fault on both sides with the same three legs (path-claims,
selftest-sweep, write-axis) and the same counts, so the removal regresses no leg.
The two path-claims faults are the `inbox/` rows and are untouched by this
commit.

Rebuild test_no_path_compression_find_stable on 4 nodes so the node it asks
about (3) sits two levels down under union-by-size; the old cell built
union(0,1);union(1,2) -> parent [0,0,0,0], so find(2) rewrote nothing and a
path-compressing find passed the cell that names the mechanism.
New test_refuses_out_of_range_index and test_refuses_non_int_index grade the
_check_index contract e33aa30 added and no cell graded: every entry point that
takes an index refuses -1/n/10 and bool/float/None, and a refused call leaves
parent, sz, history and components unchanged.
Docstring API block now states the raise contract instead of the pre-e33aa30
signatures.
Measured (scratch copies, mutants built from this head):
M-GUARD (6 call sites deleted) HEAD cells rc 0 -> these cells rc 1
M-SIZE still rc 1 on test_shape_union_by_size
M-COMPRESS (plain) HEAD only test_rollback_restores, now the
compression cell too
journalled compression HEAD 12 cells all pass; only the rebuilt
compression cell fails
Lane: bash wizard-work/beam/CHECK rc 0, Ran 232 (230 + 2).
