THE DIRECTIONAL ASYMMETRY : Matter, Antimatter, and the Fifth Boundary

The matter-antimatter asymmetry has been the most fundamental unsolved problem in physics for sixty years. The Standard Model's CP-violation mechanisms are roughly ten orders of magnitude too small to account for the observed asymmetry. Speculative baryogenesis frameworks have not closed the gap. This paper argues that the failure to close the gap from within standard physics is not an indication that the right mechanism has not yet been found. It is a structural feature of the question, identical in form to the failures that produced dark matter, dark energy, the GR/QM incompatibility, and the black hole information paradox as standing anomalies in physics. The argument: every standard-physics anomaly the Observer corpus has examined dissolves under the same operation — identification of what the standard frame treats as a contingent fact requiring mechanical explanation, and recognition that the framework treats it as a structural precondition for the differentiated physical layer to exist at all. Dark matter dissolves into the Plenum. Dark energy dissolves into collapse pressure on substrate. The GR/QM incompatibility dissolves into the boundary between container and contents. The black hole information paradox dissolves into dedifferentiation. The matter-antimatter asymmetry dissolves into the directional precondition for collapse to be possible. This paper develops the fifth dissolution explicitly. It pressure-tests the directional asymmetry postulate that grounds the argument, anchors it in the convergence of three independently measured asymmetric boundary signatures (the heliopause thermal wall, the galactic halo asymmetry, the GR/QM incompatibility), and names the meta-claim that follows from five successful dissolutions: the framework's repeated success at this operation is itself a result. The paper states explicit falsification conditions and identifies the load-bearing postulate.
