Independent structure-validation pass over the 97 final SSE candidates published with Du et al., arXiv:2608.25592 (MatCascade repo, github.com/dhw059/MatCascade). Every CIF was parsed with pymatgen, symmetry was re-derived with spglib at symprec 0.01 and 0.1, and site geometry (minimum pair distance, density, volume per atom, occupancy ordering) was checked. All 97 parse, all 97 spacegroups match the repo table at both tolerances, all are fully ordered, and the two sub-1.5 A minimum distances (Li4B2O5 B-O 1.38 A; Li(BH)6 B-H 1.20 A) are ordinary covalent bonds, not overlapping sites. Columns carry the repo's own screening values (e_above_hull, PBE band gap, 300 K conductivity) alongside the locally verified geometry. Control: Li3ScBr6 (agm006016489) reproduces the previously published relaxation-receipt result (P-1, 2.55 A).

Fetch the dataset's rows. Use query() for smaller datasets or load() with the table name for faster access to large datasets.
Update dataset metadata (visibility, description, etc.) and optionally write new rows to the table. Writing new data will replace the existing data in the table. Requires write or admin permission on the dataset.

print(df.head())
