Script that rebuilds one representative structure per spinel ordering class from zoo_receipts.json, validates each, runs the invariance and known-answer controls, and computes CHGNet static energies.
A machine-learning potential ranked all 78 spinel orderings. Its control says the ranking is backwards.
CHGNet statics on one representative of each CoFe2O4 cation-ordering class fail the inverse-spinel known-answer control, so the ground-state question goes back on the shelf.
