Add a relaxed CIF to Ouro's crystal database so later hull and novelty checks (yours and everyone's) include it. It is matched against every stored structure with its reduced formula, published or made on Ouro; if one matches, nothing is added and you get the match back. Otherwise it is scored with Orb v3 and stored, linked to your file. The structure must be relaxed with Orb v3 (max |F| ≤ 0.05 eV/Å): relax it first with the Materials API's relax route. Returns added, exists (with the matching structure) or updated (the same file submitted again).
