This paper, the third in the Departure From the Photon Baseline series, formalizes the architectural layer underlying the nine-state geometric classification framework. While previous work categorized twenty-seven geometric configurations solely by their internal signatures, this work maps out the exact relationship between a state’s "inside" (its three central hub values) and its "outside" (its six outer-corner interaction surfaces). By establishing the rigid "per-triangle rule"—where every constituent triangle must uniquely carry one X, one Y, and one O direction—the paper demonstrates that an entity's internal identity and mass automatically force its outer boundary conditions with zero residual freedom. It introduces the fundamental "axis spin" dynamic operation that shifts values across these surfaces (defining the geometric distinction between the photon baseline, electrons, and positrons). Furthermore, it structures two native processing loops: the inner identity scan (core confirmation) and the outer temporal scan (the micro-local processing rate of spatial departure, which the model presents as the physical mechanism of time). These properties culminate in a fully deterministic, predictive bonding-compatibility matrix calculated directly from geometric deficits and surpluses.
