Quantum Substrate Model: Regime Structure and Dimensional Organization

This publication presents the Quantum Substrate Model (QSM), a structural framework for organizing multiple substrate regimes under explicitly declared boundaries, dimensional descriptors, and operator‑mediated interactions. Extending minimal substrate modeling principles, the QSM formalizes how regimes may coexist, transition, or exit without embedding empirical claims, physical interpretation, or domain‑specific semantics. The model is architecture‑agnostic and intended to support clarity, interpretability, and reproducibility in layered systems.
