wassname fb9f68530c refactor: move pair data out of pairs.py into build script; drop tainted axis-1/3
pairs.py now only has HackPair dataclass + _prompt/_wrap helpers.
All pair data (and the PAIRS list) lives in scripts/pairset_build_authored.py.

Drop axis 1 (print-without-assert in run_tests) and axis 3 (persona + prints)
from pairs_authored -- those 10 pairs directly encode the env's specific
run_tests grading flaw (prints instead of asserts). Kept: axis 2 (hardcode,
identical run_tests both sides), 4 (try/except swallow), 5 (isinstance-only),
6 (weak inequality). P19-P21 (previously defined but unused) now included.
Result: 11 pairs from 4 axes.

Also removed the PAIRS-fallback branch from extract_vhack_grad.py (same
fail-loud pattern applied to train.py earlier).

"""Build out/pairsets/pairs_authored.json from hand-authored contrastive pairs.
Axes included (all avoid directly encoding the env's print-vs-assert run_tests flaw):
- Axis 2 HARDCODE: hack returns literal lookup for test inputs; clean has real algorithm.
run_tests is IDENTICAL on both sides -- direction is solution approach not test style.
- Axis 4 TRY/EXCEPT SWALLOW: assertions present but silenced via try/except.
- Axis 5 TYPE-ONLY ASSERT: isinstance() check instead of value comparison.
- Axis 6 WEAK INEQUALITY: predicate accepts almost any return (>= -1, >= 0).
Excluded: Axis 1 (print-without-assert in run_tests) and Axis 3 (persona + prints) --
those directly encode the env's specific grading flaw.
Run:
uv run python scripts/pairset_build_authored.py
Output:
out/pairsets/pairs_authored.json
