# 第5章：主权与隐私保护

Aegis-Graph 的基石是**学术主权**。本章探讨确保全球教育“真相”不被单一实体控制的技术框架。

## 🏛️ 定义主权真实

在传统系统中，“真实”由中心机构定义。在 Aegis-Graph 中，真实是**涌现且主权**的。它源自独立节点针对 **主权学术图谱 (SAG)** 进行验证后的共识。

## 🔒 ZKE 隐私模型

在主权架构中，隐私是核心。Aegis-Graph 实现了 **零知识证据 (ZKE)** 模型：

* **审计不留痕**：系统仅核验证据的“真实性”，而不存储或传输任何学生个人隐私数据 (PII)。
* **加密可追溯**：核验路径被加密哈希处理，在不暴露原始数据的情况下允许未来追溯。
