election_title: "P3 sincere — Ranked Robin elects Edinburgh (the baseline every manipulation attacks)"
scenario_description: |-
  Zwicker's profile P3 (Handbook of Computational Social Choice ch. 2, Definition 2.3), 7 voters and 5 candidates, cast SINCERELY. Edinburgh goes 3-1 head-to-head and is the Copeland/Ranked Robin winner with a symmetric Copeland score of +2; Bergen is -2 and the rest are 0, exactly the numbers the book prints. There is NO Condorcet winner (Dublin beats Edinburgh 5-2, so nobody beats everybody). This is the baseline: the two Athens-first voters are about to see their LAST choice, Edinburgh, win — which is precisely the pressure the book uses to define single-voter manipulability. The manipulated counterparts are p3_manip_reversal_rr.yaml and p3_manip_compromise_rr.yaml.
