    B.FPATR bit 9 MUST enable one final mathematical Local CScale source only for FP32 TMATMUL.ACC and TMATMULMX.ACC. CScale MUST be U8 CUBE_M32 [M,1], MUST not alias any output, and MUST scale C[m,n] by 2^-CScale[m,0] before RowMax, GroupMax, activation, quantization, and destination conversion. Bit 10 MUST remain reserved zero; disabled CScale MUST preserve prior results.
