Computational Companion with Exploratory Cross-Domain Galaxy Appendix: External Transferability Test of a Boundary-Sensitive Computational Framework

This record contains the integrated release package for the manuscript Computational Companion with Exploratory Cross-Domain Galaxy Appendix: External Transferability Test of a Boundary-Sensitive Computational Framework. It includes the main PDF, LaTeX source, figures, and bundled supporting materials.The release combines the main computational companion manuscript with an exploratory galaxy-based applied appendix. The appendix is presented as an external transferability test of the boundary-sensitive computational framework across domains, and not as a direct final proof of the broader theory. Its role is methodological: to examine whether the same descriptive logic can extract structured quantitative differences from real astronomical image data.This archive is intended as a citable scholarly release and versioned research package.Copyright notice: This work is licensed under CC BY-NC-ND 4.0.
