Abstract: A black hole horizon carries exactly one nat of information per Planck cell, without naming what the black hole is made of. Two inputs suffice: entropy is irreducible uncertainty (the configurations no observation can resolve at the Planck floor, an objective bound, not ignorance), and the horizon is a complete scrambler, so by the Ehrenfest time its Wigner function has folded below the floor and no cell can be certified empty. A single cell then holds unresolved filament crossings; a cell crossed n times admits orderings that scrambling erases, so cardinality n carries weight and its count is , one nat. The independent cells give , hence S = N . Multiplied by the kinematic factor (the causally accessible fraction of the null phase space, established separately), this returns . The derivation invokes no field equations, no microscopic theory, and no posited Hilbert space.
