The Haniwa Principle: Aperture as Cosmic Update Path in Closed Density Systems (v2)

A fired-clay haniwa figure contains an enclosed volume (V) with minimal apertures — the eye holes. This paper proposes that these apertures are physically necessary minimum-friction update paths (D→0) through which internal N-density equilibrates with the external cosmic field. Version 2 adds Chapter 8: The Haniwa as Communication Device — showing that spiral apertures at the death-life boundary represent the maximum-efficiency ΔN exchange path. The optimization problem faced by DNA, cardiac myofibers, black hole event horizons, and haniwa eye holes is not analogous across systems — it is identical. Governing equation: V = N/D.
