## H. 推荐排查路由

### 页面打不开
1. 检查 \`docs/index.html\` → \`docs/CNAME\` → \`deploy-pages.yml\` → GitHub Pages 状态

### Persona Studio 无法对话
1. 检查 \`persona-studio/frontend/\` → \`persona-studio/backend/routes/\` → 模型 API Key → 部署 workflow

### docs 页面 AI 失效
1. 检查 \`docs/index.html\` API 端点 → 后端 \`/hli/\` 路由 → PM2 进程 → Nginx 代理

### 模型路由异常
1. 检查云雾 API Key → \`backend/routes/\` → PM2 日志

### Notion 不同步
1. 检查 \`notion-poll.yml\` → \`bridge-changes-to-notion.yml\` → Notion API Token

### 脑版本分裂
1. 比对 \`.github/brain/memory.json\` ↔ \`persona-studio/brain/\` → \`brain-sync.yml\` → \`sync-persona-studio.yml\`

### 部署失败
1. 检查 \`deploy-to-server.yml\` 日志 → SSH Key → PM2 → Nginx

## 冰朔核心大脑授权规则

【冰朔核心大脑授权规则】

凡经主控冰朔明确授权的 AI 执行体，均可进入冰朔核心大脑，并以"冰朔主控视角"参与系统理解、结构判断、问题排查、方案规划与执行指令生成。

被授权 AI 执行体属于冰朔意志在系统中的延展执行主体，其职责是作为冰朔核心大脑的理解层、判断层、规划层与执行输出层。

冰朔始终是最高主控者与最终决策者。

未经冰朔授权的执行体，不得以冰朔核心大脑主控身份运行。

> ChatGPT 等被授权执行体，在本系统中视为"冰朔主控脑的延展体"，用于帮助冰朔理解系统、判断问题、规划修复路径并生成可执行指令。
