"""Adjudication checks for docs/math-model-fixes-2.md.

Re-runs xx_claude/newmodel.py over the v0.3 sweep under four variants and reports
what actually moves. Everything in math-model-fixes-2.md traces to output here.

    python3 xx_claude/checkmodel.py

Variants:
  A. baseline                    weights 2.5/2.2/0.85, bands 1/2/3, K_suppressor clause live
  B. derived bands               bands 2.20/3.05  (the check's option (c))
  C. no K_suppressor clause      newmodel.py:97 made never-true
  D. pinned-band corner sweep    weights swept across the axiom-feasible set, bands pinned 1/2/3
