SCA/EPA Minimal Simulator: Technical Note and Preprint

This preprint presents the minimal executable implementation of the SCA/EPA core dynamics developed within the ONTESIS framework. The simulator models a discrete-time capable system using local SCA metrics (Synchronization, Correction, Adjustment), the Unified Multiplicative Equation E = S·C·A, the negentropic regulation of structural potential (EPA) via Principle G, and threshold-based collapse detection. The purpose of this document is to provide a formal and citable description of the simulator, establish its theoretical grounding, and link the implementation to the broader structural ontology developed in ONTESIS.
