Non-streaming strategies require lookup abstractions (Counter, set, binary search) as load-bearing infrastructure between pipeline phases, while streaming requires none — this asymmetric abstraction overhead causally explains the strategy hierarchy: streaming dominates because it avoids the data-structure selection and initialization cost that alternatives impose on each solution author.
Streaming's privilege is the inverse of alternatives' abstraction burden; combining the load-bearing role of lookup abstractions with streaming's privilege reveals the causal mechanism
