election_title: "Nine candidates, 25 voters — ranking all nine, counted by RCV-IRV"

scenario_description: |-
  THE EXPRESSIVE BALLOT DOES NOT RESCUE THE COUNT. These are the same complete,
  full-resolution rankings as bv2280_37yf8x_rr_full.yaml — every voter's
  opinion of all nine candidates, nothing rounded and nothing truncated. Instant runoff
  still elects Ben, not the Condorcet winner Finn.

  That is the point this file exists to make, and it is the cleanest comparison in the
  folder because only ONE thing differs from the Ranked Robin control: the count. Same
  voters, same paper, same ink — Ranked Robin returns Finn and RCV-IRV returns Ben. So
  the paper cannot be what decided it.

  The mechanism is center squeeze, sharpened by the crowd: Finn stands in the middle of
  nine candidates on one spectrum,
  so the first-choice votes that elimination reads are split among the neighbours, and
  Finn is eliminated before the head-to-heads Finn wins are ever consulted.

  It also explains a measured oddity on the topic page: IRV's Condorcet efficiency barely
  moves when you hand it a coarse ballot instead of a fine one, because it only ever
  reads each ballot's top surviving choice. Resolution it never looks at costs it
  nothing — and buys it nothing either.

  Construction: build_cases.py in this folder. 25 voters and 9 candidates at frozen
  positions on one spectrum — Ada −0.73 · Ben −0.37 · Cleo −0.18 · Dev −0.17 ·
  Emma −0.11 · Finn +0.24 · Gus +0.41 · Hugo +0.80 · Iris +0.84; utility = minus the
  distance; scores = each voter's own min-max scaling onto 0–5; rankings = those same
  utilities in order. Nothing is tuned to the result, and **no count in this folder is
  settled by a tie-break** — that was a search constraint, so every winner here survives
  any lot rule.
