verify_line_counter.sh pinned the pre-Q125 tool at a host path
(/root/.hermes/wizard-outputs/spark/line_counter.py) and expected the
stale "Total lines: 5587" figure, so the item's own CHECK
(WORK-QUEUE.md:13377) reddened: usage-line output, rc 1.
Repair (confined to wizard-work/spark):
- verify_line_counter.sh resolves line_counter.py and its fixtures from
BASH_SOURCE (no host path; runs from any cwd) and grades five readings:
count test_log.txt == wc -l == 10; csv test_data.csv == csv-module
field count == 5; count test_blank.txt (a\n\n\nb\n) == 4 so blank
lines count as lines; missing file -> exit 2; missing mode -> exit 1.
- test_line_counter.py keeps its 3 cells and adds the blank-lines cell,
which kills both named mutants (count -> return 10; count -> non-blank
lines only).
- test_blank.txt: new fixture, exactly printf 'a\n\n\nb\n' (4 lines).
- README.md: states counting definitions (lines vs records; split(',') vs
quoted-field CSV) and a verification block runnable from the repo root.
- VERIFICATION.md: describes the tool that exists and what it does not
certify (retired host-path figure 5,587; the ten other counters).
Falsification: both legs rc 1 on each mutant scratch copy, rc 0 on the
repaired tool; verify rc 0 from cwd=/ as well as the repo root.
Q125's own CHECK exits 0 at this HEAD.
