The Lambda-CDM model postulates a lossless cosmic expansion, leaving the empirical Hubble tension (~5. 9 km/s/Mpc) as an unresolved astrophysical paradox. This paper presents a deterministic solution based on Dissipative Information Topology (DIT framework). The vacuum space is modeled not as an ideal fluid, but as a discrete, tetrahedral SU (2) matrix subjected to continuous topological shear pressure caused by the dimensional projection of a hidden SU (3) layer. To quantify this metric friction loss, the Law of Topological Dissipation (GammaDIT) is formalized. The expansion dissipation is derived via two strictly isolated mathematical pathways: thermodynamically, utilizing the absolute shear velocity of the dimensional wall (vwall = 207. 542 km/s) as a dynamic variable relative to the current cosmic calibration cycle; and purely geometrically, applying the length contraction of the 3D to 2D projection variance (1 - 1/√3) as a static constant across the 14 structural elements of the elementary spatial node. Both methods converge precisely on a dissipative distortion factor of 5. 925 km/s/Mpc. The calculations mathematically demonstrate that the Hubble tension is not an instrumental measurement error, but the current epochal state of an evolving topological law, defining the absolute energetic cost of spacetime expansion today.
