election_title: "Summability demo — Combined (A+B), counted by Ranked Robin"
scenario_description: |-
  The two districts merged, counted by Ranked Robin. These are the SAME ranked
  ballots IRV could not combine (under IRV, B wins both districts yet is
  eliminated when merged — see irv_combined). Ranked Robin's pairwise matrix is
  summable: District A's matrix + District B's matrix EQUALS this combined matrix
  cell-by-cell, and from it B beats A (11–9) and C (11–9) → B is the Condorcet
  winner. The candidate who won both districts wins the merge, reached by adding
  precinct tables, never pooling ballots.
