Consolidated NEMAD Tc bias analysis across four hexagonal structure families. D019 Mn3Ga: +70.3 K overprediction. Nowotny Mn5Ge3: +67 K overprediction. NiAs MnBi: -91.8 K underprediction. tau-MnAl P63/mmc: qualitative failure - NEMAD assigned 343.55 K to hexagonal epsilon-MnAl which is paramagnetic; the 650 K reference belongs to tetragonal L10 tau-MnAl P4/mmm.
