election_title: Co-op board — Yes/No approval ballot (same nine voters)
voting_method: Approval_Multi_Winner
num_winners: 3

scenario_description: |
  The APPROVAL half of the matched pair. Same nine co-op members, same
  opinions as coop_board_scores_allocated.yaml -- projected onto a Yes/No
  ballot by a stated rule: APPROVE IFF SCORE >= 3.

  The threshold is a choice, and it is the whole experiment. State it, and
  read the result as evidence about this projection rather than about
  approval voting in general.

  Approval counts: Chris 9, Dana 5, Ella 5, Ben 4, Amy 2.

  The LH engine counts this file as BLOC approval (top-N by approvals). The
  PROPORTIONAL approval rules -- seq-Phragmen, PAV, seqPAV -- are not in the
  LH engine; run them with the abcvoting wrapper:

    .venv/bin/python 06_Other/abcvoting_tabulation_engine/abc_tabulation.py \
      method_comparisons/proportional_ballots/cases/coop_board_approval.yaml

  All four approval rules agree here: Chris, Dana, Ella. The score ballot's
  two proportional tabulations both say Ben, Chris, Dana.
