One of the greatest open crises in modern cosmology is the baryon asymmetry—the fact that matter survived from the primordial plasma, while primordial antimatter completely vanished. The Standard Model attempts to explain this state through CP symmetry violation, the magnitude of which is, however, insufficient by several orders of magnitude. This paper presents an engineering solution within the framework of continuum mechanics of the Hydro-Elastic Model (HEM). We prove that antimatter is not fundamentally stable but is subject to mechanical phase erosion. We derive a universal lifetime equation for topological knots under the influence of the assimilative macro-pressure of Phase A, which impacts the 3D membrane with a hydrodynamic vorticity known as the Weinberg angle (W). By introducing a topological yield point, we analytically calculate the mechanical Freeze-out for proton stability at 3. 7 μs, which, without the use of thermodynamics, exactly corresponds to the Hadron epoch. We prove that after the boiling of the early membrane subsided, primordial antimatter was trapped in a lethal time window, and its quantity exponentially eroded to an absolute mathematical zero. Finally, we quantify the phase erosion for today's residual macro-pressure of the universe (Dark Energy), thereby predicting the hydro-elastic half-life for the secondary positron (19, 500 years) and the antiproton.
