# expect: has 2 value(s), expected 3
# NEGATIVE — wrong number of columns (3 candidates, a 2-value row).
# Original intent (BV20_neg1): number_of_races: 2 but only race_1 defined.
#   The current engine is single-race (flat schema), so multi-race can't be
#   expressed — repurposed to a column-count negative on a 3-candidate Approval race.
# Current engine error: "has 2 value(s), expected 3".
