The complete three-tier reduction hierarchy (mathematical reduction → streaming → preprocessing pipeline) mirrors the domain's quality fixed point along its algorithmic axis: the judge reward signal creates an implicit preference gradient favoring solutions closer to the mathematical-reduction end (O(1) > O(n) > O(n log n)), while the quality dynamics simultaneously freeze engineering discipline at every tier, producing a sophistication gradient in the algorithmic dimension with no corresponding gradient in the engineering dimension — the hierarchy is domain-shaped, not developer-shaped.
The reduction hierarchy's three tiers align with decreasing computational complexity, which aligns with increasing judge reward — the hierarchy's structure is explained by domain selection, not individual developer choices
