Correlated mass disorder in uniform and quasiperiodic phonon chains at matched spectral rank

This record contains the numerical data, analysis scripts, validation outputs, software-environment information, and figure-generation code supporting the manuscript “Correlated mass disorder in uniform and quasiperiodic phonon chains at matched spectral rank”. The archive supports the clean-spectrum, physical-displacement inverse-participation-ratio, transfer-matrix, correlation-response, finite-length, and spectral-rank analyses reported in the article. It includes archived numerical arrays, figure-to-data mappings, reproducibility scripts, dependency specifications, author-side validation materials, and targeted convergence checks. The archive distinguishes original production calculations from later validation and verification runs and documents estimator differences and methodological limitations. Spectral-rank matching does not equalize local gap distance, density of states, group velocity, absolute perturbation variance, or the frequency prefactor of the transfer perturbation; accordingly, the archive supports the conditional conclusions stated in the manuscript rather than a unique microscopic mechanism.
