election_title: "BV2269 — Three candidates, three seats: a race nobody can lose"

scenario_description: |-
  A behaviour probe, not a lesson with a winner. Three candidates stand for
  three seats, so every candidate is seated no matter how anyone votes — the
  membership of the board is settled before a single ballot is cast. The
  question is what a tabulator does with a contest that cannot decide anything.

  THIS FILE DOES NOT TABULATE, AND THAT IS THE POINT. The LH engine refuses an
  election of this shape outright:

      Error: cannot fill 3 seats from 3 candidate(s).
        num_winners must be smaller than the number of candidates.

  It exits 1 and counts nothing. There is no _tabulated mirror and no
  expected_winners, because the engine never produces winners. The sibling
  file race_nobody_can_lose_two_seat_control.yaml holds the SAME seven ballots
  with one seat removed, and counts normally — that is the control.

  BetterVoting answers the other way: it accepts the race (BV2269, t488h9) and
  seats all three, in score order Abby, Bruno, Celia. Seats 1 and 2 run real
  STAR rounds — scoring round 28 / 23 / 16, then runoffs won 5-2 and 5-2, no
  voter at Equal Support, tieBreakType "none" throughout — so the SEAT ORDER
  carries real information even though the membership does not. The third
  round has one candidate and nothing to run against, and BV neither prints a
  phantom runoff nor leaves a silent gap: the results page reads "Celia is the
  only candidate, and wins by default", and the round's JSON carries an empty
  runner_up and an empty logs array.

  Neither engine is wrong. LH treats "seats >= candidates" as a spoiled
  premise and refuses to pretend; BV accepts it and degrades gracefully into
  saying so. The shape is not exotic — an organisation creates it by accident
  every time nominations exactly fill the board.

  Write-ins were disabled on the BV election on purpose: a single write-in
  would supply the fourth candidate the premise excludes.
