election_title: "Chicken / Burr dilemma — Approval, honest: A and B tie 60-60 (the trap)"

scenario_description: |-
  The same electorate as chicken_star, under APPROVAL voting with honest ballots: the 60
  A/B voters approve both allies (utility above the midpoint), the 40 C voters approve C.
  Result: A 60, B 60 — an exact tie (broken here only by candidate priority order), with
  C safely defeated at 40. This is the chicken / Burr dilemma: the honest cooperative play
  leaves A and B in a dead heat, so each side is tempted to bullet-vote (approve only its
  favorite) to win outright — a slippery slope that, if both sides defect far enough, lets
  the majority-opposed C slip through. The A/B tie is the whole point (as with Jefferson &
  Burr in 1800), so this case is LH/pref_voting-verified rather than frozen from a random
  BetterVoting tie-break. STAR removes the slope entirely — see chicken_star.yaml.
