C6 – D4: Formale Struktur der Invariantenkerntheorie (Referenzfassung v24)

This component contains the formal core document of the Invariant Core Theory (ICT), Version D4 v24 (Reference Edition, 12 February 2026). D4 defines the structural foundations of the theory, including: consistency as admissibility condition, closure structure and minimal completions, invariant core definition, principles P, M, and K, structural ordering (Eigenzeit), closure capacity and regime conditions (TR*, S2, WIN), and the audit summary of the formal kernel. This document constitutes the stable reference version of the formal structure of ICT. Subsequent regime documents and representational constructions explicitly refer to this edition. The document was developed in collaboration with an AI-based formal reasoning system (ChatGPT, OpenAI), which contributed to structural consistency checks, terminology refinement, and audit transparency. All conceptual responsibility remains with the human author.
