The Haniwa Principle: Aperture as Cosmic Update Path in Closed Density Systems (v3 — Complete Edition)

Complete 12-chapter edition. The Haniwa Principle proposes that the eye holes of ancient Japanese haniwa figures are not decorative but physically necessary minimum-friction apertures through which internal N-density equilibrates with the external cosmic field. This principle — governed by V=N/D — is shown to be universal across all scales of reality. New in v3: Chapter 9 (Kofun as macro-scale V=N/D structure and keyhole geometry as physical necessity), Chapter 10 (Nobunaga skull cups as gold-lacquered D→0 aperture optimization), Chapter 11 (Human body as mobile haniwa — bone as structural vessel, flesh as N-field), Chapter 12 (Unified summary). The optimization problem faced by haniwa eye holes, DNA helices, cardiac myofibers, and black hole event horizons is not analogous across systems — it is identical. Governing equation: V = N/D.
