Data and code for response-symbol computational verification in a fractional nonlocal Gross-Pitaevskii equation

This record provides the supplementary data and code associated with the manuscript “A response-symbol verification framework for unstable-band topology in a fractional nonlocal Gross-Pitaevskii equation”. The package contains scalar response-symbol verification tables, root-bracketing and derivative-stationary certificates, Taylor edge residual checks, numerical validation tables, figure-supporting data, and scripts for reproducing the reported verification checks. The package is intended to support peer-review reproducibility of the analytical and numerical claims reported in the manuscript.
