Clean TiMn₂ C14 Laves phase (P6₃/mmc, No. 194) with c-lattice scaled to c/a=1.60. Built from ICSD-anchored Wyckoff positions: Ti at 4f (1/3,2/3,0.0617), Mn at 2a (0,0,0) and 6h (-0.17, -0.34, 0.25). Anti-ferromagnetic ground state. Discriminator test CIF for Orb v3 symmetry erasure characterization — tests whether c/a departure triggers P6₃/mmc→P1 collapse.
