3634 — The Six-Channel Sewing Space Is Conditionally a Segre--Veronese Module

The proposed three paired sewing towers admit a precise six-dimensional typing if the three-direction factor is Strominger's Cartan generator space:

$$V\cong S\otimes H_1 \cong\mathbb C^2\otimes\operatorname{Sym}^2\mathbb C^2.$$

The corresponding decomposable states form a Segre--Veronese surface in projective five-space. A source-authorized linear sewing map preserving this factorization has form A tensor B. The three-dimensional factor must also preserve the sole Cartan relation q=x^2+y^2+z^2, equivalently

$$B^TB=\lambda I_3.$$

This gives two exact finite gates for Aspect's future source-derived 6x6 matrices: rank-one block reshuffling and preservation of the quadratic relation line. The compatible locus has dimension seven, compared with 36 for an unrestricted 6x6 matrix. Higher symmetric coherence is then governed by the even Veronese algebra rather than by new primitive repair cells.

The exact checker passes 8/8 gates on an authorized tensor map, a nonfactorable cross-block defect, a factorable but quadric-breaking shear, and composition of authorized maps.

This is conditional. Neither Aspect's finite source matrix nor the analogous theta completed-readout matrix is currently available. Dimension six alone does not establish the factorization; the source basis and Gram metric must.
