This part establishes a foundational distinction between information and entropy, arguing that information is a primary physical quantity not reducible to thermodynamic disorder. While entropy measures statistical uncertainty over microstates, information refers to constraint-preserving records, correlations, and closure-stable structures that survive across physical processes. The papers develop information as: Constraint-bound rather than state-count-based Record-preserving rather than energy-dissipative Law-respecting rather than merely probabilistic Information is treated as a physical invariant under lawful evolution, distinct from entropy production, thermalization, or coarse-graining. This framework clarifies long-standing confusions in black hole physics, quantum measurement, conservation laws, and records without microstates. Part 37 serves as a bridge between earlier work on spacetime, horizons, and closure, and later developments on records, law, and misuse, positioning information as a foundational concept of physical reality rather than a derivative statistical artifact.
