Unified Pathophysiological Interpretation of Hypothyroidism Based on the 9-Keel TOFD Theoretical System: TIFD > C

This work is Paper 8 of the 9-Keel Unified Theory Series, applying the definitive TOFD > C paradigm (DOI: 10.5281/zenodo.19676866) to Hypothyroidism. It frames hypothyroidism as a systemic repair failure syndrome driven by Tissue Intrinsic Functional Deficiency (TIFD) exceeding homeostatic repair capacity (C, defined as the Ang Constant), rejecting the traditional narrative of autoimmune thyroid destruction. The work adheres to the core axiom: "Cells have no subjective will, no self-attack behavior, no pathological rebellion."
