Torqued Substrate Theory - Electromagnetism (Expanded Module)

This expanded module presents the Electromagnetism regime within Torqued Substrate Theory (TST), treating classical EM as a projection-consistent regime rather than an ontological field theory. It includes explicit admissibility conditions, non-claims, and a regime boundary diagnostics appendix (EM-B) that provides operational criteria for detecting approximation breakdown and projection exit. The module is intended as a discipline-specific reference for readers already familiar with TST’s core ontology and formalism. Version 1.1: Adds Appendix EM-B (Regime Boundary Diagnostics) and clarifies admissability conditions.
