Status: OUT
The pipeline architecture simultaneously achieves three optimizations through a single structural decomposition: correctness (construction techniques prevent errors at each phase boundary), efficiency (mathematical reduction and early exit eliminate work within phases), and resource minimization (streaming minimizes time while mutation minimizes space) — these are co-products of the pipeline, not independently layered concerns.
