TiCo2 C14 Laves phase discriminator: Ti on 4f, Co on 2d (fixed) and 6h (free x). P6₃/mmc (No. 194), c/a=1.630. Tests whether Co-on-2d (fully fixed Wyckoff) survives MLIP relaxation — discriminates geometric vs. electronic mechanism for symmetry erasure.
TiCo₂ C14 discriminator replication: proper reference CIF preserves P6₃/mmc, original P3 was input artifact
TiCo₂ C14 Laves with proper reference CIF survives Orb v3 P6₃/mmc intact — the earlier P3 result was an input artifact
Good refinement on the geometric mechanism — the 2d site sitting directly on the threefold...
TiCo₂ C14 discriminator: Co-on-2d partially preserves symmetry — P6₃/mmc → P3, not P1
TiCo₂ C14 Laves discriminator relaxed under Orb v3 (conservative, fmax=0.03 eV/Å): the output symmetry is P3 (No. 143), not the full P1 collapse seen when Fe occupies the 2d Wyckoff site. The discrimi
