Status: OUT
The preprocess-then-stream pipeline decomposition serves a dual structural role: it is simultaneously the classification criterion that partitions the solution taxonomy into three exhaustive strategies AND the optimization mechanism that achieves correctness, time efficiency, and space efficiency — the same structural cut that classifies solutions also optimizes them.
Both depth-5 conclusions depend on the pipeline decomposition for different properties (taxonomy closure vs triple optimization); combining reveals a single structural principle performing dual duty
