election_title: "Hamlin & Hua §4.1 — the assumed preferences, counted pairwise: A is the Condorcet winner"

scenario_description: |-
  The SAME electorate as hh41_01_approval_as_printed.yaml, but reading the
  paper's ASSUMED PREFERENCES as ranked ballots instead of the approval marks
  they were compressed into:
    60 voters: A > B > C
    30 voters: B > C > A
    10 voters: C > B > A

  The paper opens §4.1 by observing that "there is not always a Condorcet
  winner." True in general — but this profile has one, and it is A: A beats B
  60-40 and beats C 60-40. So A is not merely the first choice of a majority
  (the majority criterion), A is also the candidate a majority prefers in every
  head-to-head. Ranked Robin, Choose-One and RCV-IRV all elect A here; the
  approval count elects B.

  This file exists to establish that fact from the engine rather than by hand,
  because it is the one thing the paper's own framing does not say about its
  own example.
