In this work, we investigate the Hubble tension directly within the parameter space, decomposing it into two fundamental components: a displacement between the best-fit points and the directional curvature, which quantifies the statistical penalty imposed by the data. Within the Gaussian approximation [26, 27], the quadratic tension along a chosen direction factorizes into the squared parameter shift and the combined curvature supplied by the contributing probes [5, 28].
