Column name "Hardware Cost" strongly signals real_additive (cost is an extensive quantity). The data shows large absolute magnitudes (min ~3.5M, max ~7.1B), strictly positive values with no zeros, and center far from 1.0—all consistent with an extensive cost measure. No multiplicative naming tokens present. Sum is the natural aggregation for combining hardware costs across entities. </reasoning> <table_type_conflict>false</table_type_conflict> </result> ```
