election_title: "Bloc STAR — a seat-1 lot decides who wins seat 2 (lot A: Nadia first)"

scenario_description: |-
  Three candidates for a two-seat arts council, five ballots. Nadia and Omar
  tie at 15 points; Priya trails at 12, so Nadia and Omar are the seat-1
  finalists. Their runoff is a dead heat (2 - 2, with 1 Equal Support), and
  every deterministic rung ties behind it: score 15 - 15, five-star 3 - 3.
  The five-star rung is LIVE here (both hold three 5s) and still cannot
  separate them, so seat 1 falls to the published lot.

  This file pins the lot to [Nadia, Omar, Priya], so Nadia takes seat 1. Omar
  then meets Priya for seat 2 and LOSES that runoff 2 - 1 (two ballots score
  them both 5). Winners: Nadia, Priya.

  The companion file bloc_lot_path_dependence_b_c3_b5.yaml is the identical
  election with the lot reversed: Omar takes seat 1, Nadia then meets Priya
  and BEATS her 3 - 2. Winners: Omar, Nadia.

  The point is that the two runs differ in WHO WINS, not merely in the order
  the seats were filled. Priya is on the council in one and absent from the
  other, and no ballot changed. Bloc STAR is sequential - each seat is decided
  in the field the previous seat left behind - so a tie broken at seat 1
  propagates into every later seat. In a top-N method (Bloc Approval, SNTV,
  Bloc Ranked Robin) a tie can only ever swap the last seat.

  Why the two head-to-heads differ: Omar and Priya are scored 5/5 by the two
  ballots that would otherwise separate them, so Omar wins only 1 of the 3
  decided ballots; Nadia and Priya are never tied on any ballot, and Nadia
  takes 3 of 5. Same pair of near-identical candidates, opposite results
  against the same third one.

  LH-only (no BetterVoting election): the winner turns on the lot, and only
  LH's published lot_numbers let a reader derive the result from the file.
