ZBT Cosmology: Discrete Bit Spacetime Lattice Data Substrate — The Origin of Time and the First Principle of Informatio

systematically constructs a complete mathematical and data architecture for the discrete bit spacetime lattice model. Seven self-consistent fundamental axioms are proposed to establish the discrete-bit nature of cosmic spacetime. A three-dimensional uniform lattice cell coordinate system is constructed, and three core governing equations are derived: the global information functional, the energy quantization relation, and the transport dynamics equation. We demonstrate that fundamental lattice perturbations induce the CP symmetry breaking mechanism of weak interactions, and further prove the macroscopic-limit consistency between this model, general relativity, quantum mechanics, and gravitational theory. Six categories of standardized simulation-data stratified storage frameworks are defined, and two major engineering application paths -- quantum-chip simulation and solid-state-battery transport simulation -- are extended. This chapter provides a unified equation foundation and underlying data substrate for large-scale lattice numerical computation and experimental data fitting in subsequent chapters.
