Appendix MTH — Mathematics in Dualbind

Appendix MTH (Mathematics) is the entry document and handling guide for the Math Boundary series.It does not propose a new mathematical theory, nor does it attempt to adopt, integrate, or justify Dualbind through existing frameworks. Instead, it records—as a boundary log—where formal mathematical descriptions remain valid, and where structural limits become exposed under Dualbind’s observational conditions. This appendix defines the series’ stance and usage: what “boundary” means in this context, what is being recorded (differences in scope, not refutations), and how the subsequent appendices should be read as symptom logs rather than domain-wide judgments. Appendix MTH functions as the “door” of the series: it clarifies the scope, prevents over-analogy, and preserves the separation between creation logs (authorship/work date) and publication logs (Zenodo release).
