Part IIUnitary Central Even Product
Abstract
Actual part iiunitary central even product supplies the parameterized matrix, finite-field or ordered-product identities consumed by the whole-SU K5 width and intrinsic prescribed-product proof paths. All original hypotheses and actual carriers are retained; this source provides no oracle for bare automorphism recognition.
Theorem 1.1 (actual uniform central even U product).

Commentary.
Actual uniform prescribed diagonal/field VALUE coverage of the ENTIRE even-dimensional central positive unitary U1. Length/cutoff precede all fields/ranks/tuples; ONE ambient unitary h precedes all actual targets b, and every witness is positive UNITARY.
The results concern special-unitary matrix groups over finite fields. Their geometric setting is Nikolov and Segal, On finitely generated profinite groups, II: Products in quasisimple groups, Annals of Mathematics 165 (2007), 239-273, DOI 10.4007/annals.2007.165.239. Prescribed-product statements retain their field-size, rank and automorphism hypotheses.
