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.
