The θ-vacuum structure in QCD produces observable CP violation when the theory is consistently quantized with boundary degrees of freedom accounted for in the infinite-volume limit.
CP conservation in QCD follows from taking the infinite volume limit prior to summing over topological sectors, shown consistent with steepest-descent contours and chiral EFT.
