Streaming achieves universal coverage of the solution space through two orthogonal extension mechanisms: operation specialization adapts streaming to different data domains within a single pass (XOR for bits, Counter for frequencies, min-tracking for extrema), while domain adaptation via preprocessing transforms problems from domains where streaming alone is insufficient into streaming-amenable form — specialization extends streaming's reach within its native domain, adaptation extends it beyond.
Depth-6 unification: two independently derived aspects of streaming's coverage (internal specialization vs external adaptation) are orthogonal axes that jointly explain universality
