Status: IN
The preprocess-then-stream pipeline has exactly two concrete forms — hash-then-stream (Counter/set for membership and frequency queries) and sort-then-stream (sorted order for positional queries) — matching the two preprocessing paradigms one-to-one with a single shared consumption phase.
The canonical pipeline and the preprocessing partition are the same dichotomy viewed from different angles — one structural, one problem-theoretic
Depends on (SL): preprocess-then-stream-is-canonical-pipeline, two-preprocessing-paradigms-partition-problems
