election_title: "BV parity — Approval: most approvals wins (single winner)"
scenario_description: |-
  Ported from BetterVoting's tabulator unit tests (Approval.test.ts :: "Single Winner Test").
  Dave has the most approvals and wins. In the original two rows carried out-of-bounds
  marks (a 2 and a -1) that BetterVoting counts as 0/not-approved; here they are written
  as plain 0 so the file validates under this engine while preserving every approval total.
