The solution space possesses a provably unique canonical form: elimination and streaming independently arrive at the same extremal minimality (elimination via constructive proof through mathematical reduction, streaming via convergence-attractor coincidence with algebraic normal form), and their demonstrated duality means any alternative characterization must reduce to this one — two independent proof paths converging on the same object establishes uniqueness, not merely equivalence.
Two independent descriptions each proving minimality of the same object is the standard mathematical pattern for establishing uniqueness — if a second canonical form existed, it would have to be both elimination-minimal and streaming-minimal, collapsing to the same form
