C7 - Invariantenkerntheorie - Kanonischer Kern (D1v17)

This document defines the currently canonical structural core of the Invariant Core Theory (ICT). It contains only axioms, structural principles, and formal definitions. All other documents elaborate, motivate, test, or represent this structure but do not replace it. The development of this document involved structured AI-assisted analysis and formalization (NATHAN; ChatGPT), operating under explicit methodological constraints defined within the ICT framework.
