Part III - Interacting Coherence Wells: Substrate Dynamics of Gravity, Entanglement, and Orbital Stability

This paper extends the MID/QC framework into the dynamic regime, showing how coherence wells interact to produce gravity, orbital stability, entanglement, and quantum behavior. Building on the geometric foundation of Part II, it reframes these phenomena as emergent expressions of substrate-level coherence gradients. The paper introduces saddle geometries, coherence channels, tunneling behavior, and multi-well landscapes — all derived from simple, intuitive substrate rules. Designed for clarity and adoption, this installment completes the conceptual arc and prepares the reader for cosmological and technological implications in Part IV.
