election_title: "Summability demo — RCV-IRV district B (B wins)"

scenario_description: |-
  District B of the RCV-IRV summability trio: B wins here too — both districts
  independently elect B. Yet the combined electorate does NOT elect B (see
  irv_combined.yaml: B is eliminated first there). District winners, and even
  full district round-by-round tallies, cannot be summed into the combined
  result — the non-summability this trio demonstrates.

Winner(s) — RCV / Instant-Runoff Voting (single winner)
  B

--- Smith Set (the generalized Condorcet winner) ---
The smallest group whose every member beats every candidate outside it —
the honest answer to "who is even in contention?".
   Smith set (1 of 3): B
   Outside (2):        C, A
   One member ⇒ B is the Condorcet winner, beating every rival head-to-head.
   RCV-IRV winner B is INSIDE the Smith set. ✓
      Not guaranteed — RCV-IRV is not Smith-efficient — but it holds here.
