The cosmological LSS map is a single demo artefact distributed in the FOSCAT_DEMO repository, not a peer-reviewed scientific dataset, and it is not the data the original paper is about (Planck 353 GHz dust polarisation). A future study could test the framework on multiple peer-reviewed astrophysical datasets at the paper's native resolution to strengthen the generalisation evidence.
