The Inverse of Reality: A Structural Proof from the Limits of Appearance

What is the inverse of reality? Not its absence — absence is the failure of the condition. Not nothingness — nothingness is the collapse of the relation. The inverse of reality is the same relational structure with its values flipped: where reality holds that distinguishability exceeds indistinguishability (H > K), its inverse holds that indistinguishability exceeds distinguishability (K > H). This paper establishes both sides of the structure and identifies the one place in known physics where the inverse physically exists: the interior of a black hole. The event horizon is the seam between reality and its inverse — defined entirely from the side of H > K, because anti-reality cannot generate its own edge. From this, a prediction follows: information cannot be destroyed. Two defeat conditions are stated.
