Column name "Reported Cost" is a strong additive signal (cost is an absolute extensive quantity). The values are large magnitude (millions to hundreds of millions), strictly positive with no zeros, and unbounded upper range—all consistent with real_additive. No evidence of ratio behavior (not centered near 1.0, no multiplicative naming tokens). This is a straightforward extensive cost measure that accumulates via sum. </reasoning> <table_type_conflict>false</table_type_conflict> </result> ```
