Stage Decomposition of the Self-Consistent Inflation Mechanism and Its Full-Range Reproduction for N=3..40: A Reproduction Specification

A reproduction specification (an overview plus three chapter papers) that fixes, in a fully reproducible form, the mechanism of inflation-like development in N-body relation-wave closed systems: a seed at dormant fraction ~1e-30 amplified exponentially by the dynamics alone until saturation. The dynamics is decomposed into three stages (explicit-matrix spectral map with fixed time step; amplitude normalization of the generator; removal of the cos symmetric part yielding a real orthogonal rotation), whose necessity is established by single-factor deletion controls at N=40, and then swept over N=3..40 x 6 denominators x 500 steps from deterministically generated static parents. All equations are mapped to program lines, all programs and data carry SHA256 ledgers, and a chain of bit-identity gates connects the sweep to the July 2026 canonical runs (DOI 10.5281/zenodo.21486234). Contains no physical interpretation beyond observed facts. Japanese originals and English versions of all four papers, the complete program/data package (~476MB), and the companion single-factor experiment artifacts (~238MB) are included.
