election_title: "Nine candidates, 25 voters — ranking all nine, counted by Ranked Robin"

scenario_description: |-
  THE CONTROL. Every voter ranks all nine candidates, nothing truncated and nothing
  rounded, and Ranked Robin returns Finn — the candidate who beats each of the other
  eight head-to-head.

  This is the full-resolution ranked ballot that Condorcet-efficiency simulations
  normally hand to ranked methods. It is also an idealization: no large-field
  jurisdiction issues it. bv2280_37yf8x_rr_top5.yaml cuts it down to five
  ranks, which is what a real ranked ballot looks like, and the winner changes.

  Compare with bv2280_37yf8x_star.yaml: the 0–5 score ballot agrees with this
  one. Compare with bv2280_37yf8x_irv_full.yaml: the SAME ballots, counted by
  instant runoff, do not — which is the cleanest evidence in this folder that the paper
  and the count are separate things.

  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.
