EVA-HNS: A Structural Full-Stack Operating System for AI Alignment — Architecture and 50-Turn Evidence

EVA-HNS is a structural full-stack operating system for human-aligned AI.This working paper presents a compact research-oriented overview of the EVA-HNS architecture, integrating three layers: Human Natural Structure (HNS) as the structural coordinate kernel, SOHU (Structural OS for Human Understanding) as the operating layer for persistent human understanding, and EVA (External Verification Architecture) as the independent verification layer. The paper introduces the concept of structural hallu
