SA_4 Constraint Bundles as Load Bearing Tensors

This paper establishes constraint bundles as load-bearing tensors within an admissible descriptive system. Constraint bundles are shown to carry structural load by fixing relations that preserve standing, rather than functioning as modular components, adjustable parameters, or executable rules. By exhaustion, any attempt to decompose, tune, or repurpose constraint bundles as interchangeable elements is shown to violate admissibility and fail closed. The treatment is foundational and declarative, placing on record how structural load is borne in a closed system without introducing construction steps, transformation procedures, or operational guidance.
