Column name "corpus_docs" strongly signals a count (real_additive): "docs" is a countable entity. All values are constant at 8.0, strictly positive with no zeros, centered far from 1.0 at an absolute magnitude. This is an extensive quantity (document count) that would sum meaningfully when volumes merge. No multiplicative evidence present. </reasoning> <table_type_conflict>false</table_type_conflict> </result> ```
