A nonclassicality witness in qubits now reaches 1/4, exceeding the limitations of previous structural criteria for assessing quantum behaviour. This quantification, achieved with specific POVMs and maximal dephasing, reveals nonclassicality even when standard projective measurements fail to detect it. Connecting Kolmogorov consistency with measurement unsharpness offers a new avenue for validating quantum devices.
