We present Integrated Structural Generation Theory (IGS), a minimal and falsifiable framework in which physical, informational, observational, semantic, and temporal phenomena are unified through structural differentiation. In this framework, the universe is not described as a collection of independent objects, but as a generative chain of structured differences: Difference → Fixation → Information → Meaning → Convergence → Time Rather than introducing new physical entities, IGS reinterprets existing observations as projections of underlying structural dynamics. In the low-differentiation limit, the framework reproduces effective ΛCDM cosmology, standard quantum behavior, and ordinary time, establishing a correspondence principle with established theories. The theory is explicitly falsifiable. It is rejected if no stable mapping exists between structural difference and observables, if geometry–growth separation is absent, or if convergence occurs without structural update. IGS provides a unified structural language connecting cosmology, information theory, observation, and meaning within a single minimal framework. This work includes:- the formal definition of the IGS framework,- a complete minimal generative structure,- an explicit falsifiability criterion,- and a unified structural diagram. One-line definition:The universe is not made of things. It is made of differences that become structure.
