A.19:5.2.1.3 Product – Combination CS₁ ⊗ CS₂ = CS⊗.

The product of two spaces CS₁ and CS₂ is a new space CS⊗ whose basis is the disjoint union of both bases, so even same-named slots retain their source identity. Its state is a pair (x₁, x₂). For example, a product can combine internal capability Coordinates with external-condition Coordinates for a readiness use. The product does not aggregate them: any cross-slot scale aggregation uses a declared Gamma fold under A.19.ULSAM and any needed A.19.UNM normalization. Use B.1 when a separate holonic-composition claim is made.
