Methodological, Mathematical, and Epistemological Audit Supplement for the TBE/Biplectic Framework

This document serves as the Methodological, Mathematical, and Epistemological Audit Supplement to the TBE/Biplectic framework (linked via isSupplementTo to DOI 10.5281/zenodo.22926707). It details the internal audit results (recording 54/54 PASS) and establishes a strict epistemological boundary: [\text{Computed} \neq \text{Proven in Nature} \neq \text{Proposed}]. The supplement documents the scope of ECTE and COSMOS-Web/AMICO analyses, numerical comparisons (a_{\mathrm{turn}} \approx 1.708 vs. a_{\max} \approx 1.69), and defines the model as a testable framework rather than a pre-proven physical reality.
