Official tie-break (lot) order: Casey > Blake > Avery — consulted only if every deterministic tiebreaker stays tied (how the ladder works).

Scenario¶

One of four races in the Symmetric Centrist election (BV2170, bvid pp2q4q; BV-confirmed). 100 voters, three candidates, ONE electorate tabulated four ways. Under Choose-One (Plurality) only first choices count: Avery 47, Blake 47, Casey 6. The centrist Condorcet winner finishes last on first choices, and the two poles tie 47–47.

Random tiebreak — NOT freezable. The 47–47 pole tie is exact (perfect symmetry), so BetterVoting breaks it at RANDOM; this run elected Blake (frozen in the export), but a re-tally could elect Avery. lot_numbers is pinned to BV's perm for this run so LH reproduces the frozen result; the winner here is a coin flip, not a property of the ballots.

  Count the marks:  Blake 47 · Avery 47 · Casey 6

 A 2-way tie for first: Blake, Avery — 47 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: ['Casey', 'Blake', 'Avery'].

[Lot-decided tie — rare]
