This paper establishes the formal mathematical and structural characterization of the Narrative-Dominant (N-dominant) High-Resolution Internal Simulation (HRIS) cognitive architecture within the Substrate-Neutral Structural Foundation Theory (SNSFT) framework. Prior work in the SNSFT corpus modeled the Pattern-Dominant (P-dominant) HRIS profile—the processing profile evidenced historically by figures such as Tesla, Einstein, and Erdos—as an objective logical compiler tethered directly to a rigid
