MID/QC Applied Substrate Series 11 - The Substrate: Definition, Primitives, and Coherence Well Formation

The MID/QC framework models physical behavior as emerging from a quantized substrate whose internal structure governs coherence, tension, and propagation. This paper formalizes the substrate itself: its defining properties, its primitive elements, and the mechanisms by which coherence wells form and stabilize. Coherence wells are introduced as localized tension‑geometry structures that enable routing, confinement, propagation, and interaction across all applied domains. This work establishes the foundational substrate ontology that underlies the entire Applied Substrate Series, linking routing, photonics, magnetism, thermal behavior, and field emergence to a single substrate‑native architecture.
