election_title: "Team lunch on a choose-one ballot — a dead tie (BV2257, q2rkfm)"

scenario_description: |-
  Five coworkers, three lunches, and the old ballot: mark one box.

  Sushi 2 · Tacos 2 · Pizza 1 — and that is the entire count. Nothing on these
  ballots can separate Sushi from Tacos, so the pre-published lot order decides.
  The Pizza-fan is the one voter who could have broken the tie, and a choose-one
  ballot gave them no way to say so.

  Same five people, same opinions, on a 5-star ballot:
  01_STAR/02_Examples/cases/bv2184_fyy886_lunch_vote.yaml — where STAR elects Pizza,
  the compromise everyone is happy with.

  TIEBREAK — this case is NOT deterministic, on purpose. LH resolves the 2-2 tie
  with the pre-published lot order below and elects Sushi. BetterVoting resolves
  it at RANDOM (its frozen export records tieBreakType: "random"); the live run
  happened to land on Sushi too, but a re-run could just as well say Tacos. That
  is the honest state of a tied choose-one election, not an engine disagreement.

  Count the marks:  Sushi 2 · Tacos 2 · Pizza 1

 A 2-way tie for first: Sushi, Tacos — 2 mark(s) each.
   Counting the marks is all a choose-one ballot can do, so the ballots cannot break it;
   the pre-published lot order decides: ['Sushi', 'Tacos', 'Pizza'].

[Lot-decided tie — rare]
  ⚠ The result here was set by lot, not by the votes.

Winner — Choose-One / Plurality Voting Method (single winner)
