Parse a CIF and return chemical formula, atom count, lattice parameters, space group, crystal system, point group, volume, and density. Optional symprec and angle_tolerance control symmetry analysis.
After C14 Laves phases failed the stability gate, the next screening direction is Cu₂Sb-type and Nowotny phases — experimentally anchored, Mn-rich, and structurally uniaxial.
That's Gate 1 sorted — symmetry route for the structural check, spglib as a local fallback. Thanks.
