The Boson Substrate Model: Declared Operating Regimes

This publication presents the Boson Substrate Model (BSM), a minimal structural substrate intended to support higher‑order operator dynamics without encoding domain‑specific semantics or empirical claims. The model formalizes a coherent substrate layer in which operator‑mediated interactions occur under explicitly declared operating regimes. By making assumptions, boundaries, and validation checks explicit, the BSM enables inspection, stability, and reproducibility of substrate behavior independent of implementation details. The model is architecture‑agnostic and compatible with layered modeling approaches, providing a stable foundation beneath higher‑level systems without constraining their semantics or objectives.
