Apply the metric with these evaluation rules:
- Return false when the prediction is None, including error or refusal outcomes. section 2.4.2
GAIA answer validation
A prediction such as " Paris " matches the reference "paris" after stripping whitespace and lowercasing; a missing prediction remains incorrect. section 2.4.2
