election_title: "Summability demo — STAR combined A+B (Oak; precinct subtotals add up)"

scenario_description: |-
  Districts A + B merged (all six ballots): Oak wins the combined STAR count.
  Check it against the two district files — every score total and every
  pairwise-matrix cell here is exactly the SUM of the districts' published
  subtotals. No central ballot pile, no recount: precincts report, totals add.
  That is summability; the irv_* trio shows RCV-IRV failing exactly this
  test.
