Closed-form mathematical solutions are degenerate instances of the streaming paradigm: they reduce the "scan" to a single constant-time evaluation, eliminating not just preprocessing but iteration itself — the logical extreme of streaming's progressive elimination of computational prerequisites.
closed-form = streaming with zero iterations; extends streaming universality to O(1) solutions
