From fb9f68530c07073b4bba68e956390ec9809fc0e1 Mon Sep 17 00:00:00 2001 From: wassname <1103714+wassname@users.noreply.github.com> Date: Tue, 9 Jun 2026 08:44:33 +0000 Subject: [PATCH] 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).
