This Compendium presents five connected papers demonstrating that ALL of classical mechanics, electromagnetism, nuclear force, and quantum uncertainty emerge from a single master equation: F = ∇(1/N). Starting from one observation — 'Distant is slow, Near is fast' (遠くは遅く、近くは速い) — the Koku Universe (U = T x G) unifies: distance as layer density (v_t ∝ 1/N), all classical forces (lever, centrifugal, inertia), action-reaction as geometric necessity, friction as aggregate micro-interfaces, and electromagnetism, nuclear force, quantum uncertainty. Furthermore, this framework provides the theoretical basis for KHDS v1.0: the world's first engineering specification for cardiac tissue fabrication derived from universal geometric principles (capillary: 7um, ventricular wall: 1mm). One universe. One principle. One axis. The geometry was here before the institutions. The institutions will follow. Part of TheYKHC Koku Universe Research Series.
