election_title: "Block Voting (3 seats): the majority ceiling — a unanimous candidate holds only 33%"
scenario_description: |-
  Why "the winner got less than half the votes" cannot be read as vote splitting
  in a MULTI-SEAT choose-one race — the arithmetic forbids it.

  30 voters, 3 seats, 5 candidates. Each voter marks 3 names (Block Voting), so
  90 votes are cast in total. Alice is on EVERY single ballot — literal
  unanimity, the most consensus a candidate can possibly have.

  And Alice's share of votes cast is 30 / 90 = 33.3%.

  With k marks per voter the total is k x voters, so no candidate can exceed
  1/k of votes cast no matter how popular: 33% at 3 seats, 25% at 4, 9% at 11.
  A screening rule that flags every race whose leader is under 50% therefore
  flags 100% of multi-seat block-vote races — including unanimous ones. That is
  a denominator artifact, not evidence of a split.

  This does NOT clear Block Voting. Its real defect is the opposite one: a
  bare majority sweeps every seat (see mmp_block_voting.yaml, 60/40 -> 3-0).
  The point is narrower and cuts both ways — the sub-majority test is blind
  here, missing the actual pathology while flagging consensus as a failure.

--- Block Voting (plurality-at-large) — 3 winners ---
 Tabulating 30 ballots (3 votes/voter).

Votes (most votes fill the seats):

   Bruno    22  <- Elected
   Cleo     20  <- Elected
   Dev      10
   Esme      8

Winners — Block Voting (plurality-at-large), 3 seats:
   1. Alice   (30 votes)
   2. Bruno   (22 votes)
   3. Cleo   (20 votes)
