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 observed phenomena 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. We further introduce:- a unified structural relation linking all modules,- explicit testable predictions,- and a global falsifiability condition. The theory is rejected if no stable mapping exists between structural difference and observables, if the generative chain fails, or if independent ontological entities are required. This work includes:- a minimal formal definition of IGS,- a unified structural equation,- two complementary diagrams (framework and structural flow),- and a complete reproducible figure generation script. One-line definition:The universe is not made of things. It is made of differences that become structure.
