BU78 Projection-Stratum to Higher-Gradient Interface Theorems Material Order, Consciousness Order, and Dual-Order Interface Structure

This paper develops BU78|Projection-Stratum to Higher-Gradient Interface Theorems as a structural interface file within the B_U sequence. Its central claim is that the projection stratum cannot directly pass into higher-order gradients by simple extension, accumulation, formal equivalence, or subjective elevation. The transition from projection-level readout to higher-order retained standing is governed by a dual-order interface structure: the material order and the consciousness order. These two orders are mutually dependent and mutually constraining. A purely material account remains trapped in observable substructures, measurement windows, local perturbations, and finite formal envelopes. A purely…
