WannierTools2.7.0 Chern_3D_calc six-plane tutorial. Own2orbital d=(hand*sinx,siny,m+cosx+cosy+.2cosz),a3A,spinless;4nativeconditions. NoDFT/MD/GPU.
Every native phase checked independently by NumPy lower-eigenstate overlap loops; opposite oriented xy Berry flux checked with81/161 integral grids. Native x-loop/y-sweep Wilson winding is opposite the positive x-y oriented Berry-flux integral.
Native WT.out integer summaries incorrectly printzero for these nontrivial examples; preserved and NOT qualified. Use continuous phase winding rounded to nearest integer after adequate sampling and gap checks, independently compare Berry flux. Source uses INT rather than nearest integer, but specific internal runtime rounding values not asserted. Sharedcode unmodified.
Not a time-reversal Z2 example. Four planes without xy topology havezero winding;xy kz0/.5 have -hand for m-1, zero for m-3. Two loop densities and opposite hand checked.
