election_title: "The eight ambiguous CSV lines, disambiguated (BV issue #778 ex1)"

scenario_description: |-
  The eight-line CSV posted in BetterVoting issue #778 ("YAML File standard"),
  rewritten in this library's schema so every line states what it means.
  The bare CSV could not say whether a zero was a real low score, a blank, a
  deliberate abstention, or a spoiled ballot — and it never said which method
  to count it by. Here the method, the seat count, the candidate names and the
  intent behind every zero are all in the one file, and the engine can run it.
  Note line 7: four real zeros, cast on purpose. The engine reports 2 of 8
  ballots as abstentions - the race abstention and the spoiled ballot - and
  leaves the all-zero ballot in the count, where it belongs.
