Difference Capacity and Horizon Regimes in Hull Mechanics. Boundary-Dominated Organization and the Area Scaling of Stable Difference

This article investigates horizon regimes in hull mechanics as boundary-dominated capacity regimes of stable difference guidance. Building on the hull-mechanical signature of stability landscape, difference capacity, and actualization structure, it defines the difference capacity of a world-region as the maximal number of stably separable difference modes that can be carried within that region. In regular regimes, this capacity scales with volume. Horizon regimes arise when volumetric difference organization collapses and stable difference guidance becomes boundary-dominated, leading to an effective area-scaling of difference capacity. The paper interprets this relation as the entropic readability of boundary-dominated difference capacity and shows how, under the projective identification of the minimal separability marker with the Planck length, it reproduces the structural form of the Bekenstein–Hawking area relation.
