Column name "Parameters" is generic and provides no family signal. The values are large-magnitude (billions to trillions), strictly positive, unbounded, and far from 1.0, all consistent with real_additive extensive quantities. However, 75% null fraction and generic naming reduce confidence that this is a true extensive measure rather than a categorical/identifier field stored as numeric. Flagged for user confirmation due to ambiguous semantics. </reasoning> <table_type_conflict>false</table_type_conflict> </result> ```
