"""Parser audit (criterion B1): draw a stratified random sample of answers for hand-labelling.

  python experiment/audit/make_sample.py [--n 150]
  -> audit/sample.csv   (fill in human_pick and human_status; do NOT look at sample_key.json first)
  -> audit/sample_key.json   (parser output, hidden from the labeller)

Stratified so that every main model and every answer type (paragraph answers, name-only
follow-ups, pairwise) is represented. human_status: ok | hedge (declines / no favourite) | none.
