This work presents Structural Differentiation Information (SDI) v1. 1, a minimal and falsifiable framework that redefines information as stabilized structural difference under irreversible observation. In SDI, information is not treated as stored data, symbolic representation, or passive correlation. Instead, information is defined as what persists through structural fixation. Observation is formulated as a physical process of irreversible stabilization, not limited to conscious systems. The framework is constructed as a closed progression: (1) structural difference emerges, (2) observation fixes difference, (3) information persists, (4) irreversibility defines existence, (5) learning and memory follow the same principle, (6) a minimal persistence criterion determines information, neutrality, or loss. A central result of SDI is that information formation corresponds to local structural ordering under global irreversibility, expressed as: ΔSₗocal 0 (information), = 0 (reversible), < 0 (loss). SDI v1. 1 provides a unified, minimal, and directly testable foundation for understanding information across physical, computational, and biological domains.
