+| `{{setvar::key::value}}` | 设置变量 | `{{setvar::age::25}}` |
+| `{{delvar::key}}` | 删除变量 | `{{delvar::temp}}` |
+| `{{random::a,b,c}}` | 随机选择（逗号） | `{{random::苹果,香蕉,橙子}}` |
+| `{{pick::a\|b\|c}}` | 随机选择（竖线） | `{{pick::剑\|斧\|弓}}` |
+| `{{roll XdY}}` | 掷骰子 | `{{roll 3d6}}` |
+| `{{// 注释}}` | 注释（不输出） | `{{// 这是注释}}` |
+
+#### 使用示例
+
+```python
+from backend.services.js_sandbox import JSSandboxExecutor
+
+sandbox = JSSandboxExecutor()
+
+template = """
+{{setvar::character::勇者}}
+{{setvar::weapon::{{random::剑,斧,弓}}}}
+{{character}}手持{{weapon}}，掷出了：{{roll 1d20}}
+{{// 这是注释，不会显示}}
+""".strip()
+
+result = sandbox.render_template(template)
+print(result)
+# 输出: 勇者手持剑，掷出了：15
+```
+
+#### 脚本管理
+
+支持三种作用域的脚本：
+
+- **GLOBAL** - 全局脚本，对所有聊天可用
+- **CHARACTER** - 角色脚本，绑定到当前角色卡

+- `2` - AI Output（AI 输出）
+- `3` - Quick Reply（快捷回复）
+- `4` - World Info（世界书信息）
+- `5` - Reasoning/Thinking（推理/思考内容）
+
+#### 规则示例
+
+```json
+{
+  "id": "hide-thinking-001",
+  "scriptName": "隐藏思考标签",
+  "findRegex": "<thinking>[\\s\\S]*?<\\/thinking>",
+  "replaceString": "",
+  "placement": [2],
+  "substituteRegex": 0,
+  "markdownOnly": false,
+  "promptOnly": false,
+  "disabled": false
+}
+```
+
+### 3. 预设系统

+- 右键菜单（编辑/复制/重roll/删除）
+- 历史总结
+- 智能滚动
+
+---
+
+## 开发指南
+
+### API 路由
+
+所有 API 路由定义在 `backend/api/routes/` 目录下：
+
+- `chatWsRoute.py` - WebSocket 聊天（流式输出）
+- `chatsRoute.py` - 聊天管理
+- `charactersRoute.py` - 角色卡管理
+- `presetsRoute.py` - 预设管理
+- `worldbooksRoute.py` - 世界书管理
+- `regexRoute.py` - 正则规则管理
+- `apiConfigRoute.py` - API 配置管理
+
+### 状态管理
+
+前端使用 Zustand 进行状态管理，store 定义在 `frontend/src/Store/`：
+
+```
+Store/
+├── Mid/              # 中间区域状态
+│   ├── ChatBoxSlice.jsx      # 聊天框状态
+│   └── ChatBoxUISlice.jsx    # 聊天框 UI 状态
+├── SideBarLeft/      # 左侧边栏状态
+├── SideBarRight/     # 右侧边栏状态
+└── TopBar/           # 顶部栏状态
+```
+
+### 样式系统
+
+使用 CSS 变量实现多主题：
+
+```css
+:root {
+  --color-bg-primary: #ffffff;
+  --color-text-primary: #1a1a1a;
+  --color-accent: #667eea;
+  /* ... */
+}
+
+[data-color-theme='dark'] {
+  --color-bg-primary: #1a1a1a;
+  --color-text-primary: #ffffff;
+  /* ... */
+}
+```
+
+---
+
+## 配置说明
+
+### 环境变量
+
+创建 `.env` 文件（从 `.env.example` 复制）：
+
+```env
+# 后端配置
+HOST=0.0.0.0
+PORT=23338
+DEBUG=True
+
+# 前端代理
+VITE_API_URL=http://localhost:23338
+
+# API 加密密钥（自动生成，不要手动修改）
+FERNET_KEY=your_generated_key_here
+```
+
+### API 配置
+
+API Key 通过前端界面配置，自动加密存储到 `data/apiconfig/` 目录。
+
+⚠️ **注意**：`data/apiconfig/*.json` 已添加到 `.gitignore`，不会被提交到版本控制。
+
+---
+
+## 常见问题
+
+### 1. 前端无法连接后端
+
+**问题**: 前端请求返回 404 或网络连接错误
+
+**解决**:
+```bash
+# 检查后端是否运行
+curl http://localhost:23338/api/health
+
+# 检查前端代理配置
+cat frontend/vite.config.js
+```
+
+### 2. API Key 不生效
+
+**问题**: 配置了 API Key 但仍然无法调用 LLM
+
+**解决**:
+1. 检查 API 配置文件是否存在：`data/apiconfig/`
+2. 检查加密密钥是否正确：`.env` 中的 `FERNET_KEY`
+3. 重启后端服务
+
+### 3. Docker 部署后无法访问
+
+**问题**: `docker-compose up` 后无法访问服务
+
+**解决**:
+```bash
+# 查看容器状态
+docker-compose ps
+
+# 查看日志
+docker-compose logs -f backend
+docker-compose logs -f frontend
+
+# 重新构建
+docker-compose up -d --build
+```
+
+### 4. 正则规则不生效
+
+**问题**: 配置了正则规则但没有效果
+
+**解决**:
+1. 检查规则是否启用（disabled: false）
+2. 检查 placement 是否正确
+3. 检查正则表达式语法
+4. 重启后端服务

+└── README.md            # 本文件
+```
+
+## 模型分类
+
+### 1. SillyTavern 兼容模型 (`sillytavern.py`)
+
+**用途**: 仅用于与 SillyTavern 格式的数据进行导入/导出兼容
+
+**特点**:
+- 严格遵循 SillyTavern 官方规范
+- 不参与内部业务逻辑
+- 所有字段名、结构与 SillyTavern 保持一致
+- 前缀 `ST` 表示 SillyTavern
+
+**主要模型**:
+- `STWorldInfo` - SillyTavern 世界书
+- `STCharacterCard` - SillyTavern 角色卡
+- `STChatHeader` / `STChatMessage` - SillyTavern 聊天记录
+- `STGenerationPreset` - SillyTavern 采样预设
+- `STPromptPreset` - SillyTavern 提示词预设
+
+**使用场景**:
+```python
+# 从 SillyTavern 导入时
+st_data = json.load(file)
+st_character = STCharacterCard(**st_data)
+
+# 转换为内部模型
+internal_character = converter.st_to_internal(st_character)
+
+# 导出到 SillyTavern 时
+st_data = converter.internal_to_st(internal_character)
+json.dump(st_data.dict(), file)
+```
+
+### 2. 内部业务模型 (`internal.py`)
+
+**用途**: 项目内部真正使用的数据结构,所有业务逻辑都基于这些模型
+
+**特点**:
+- 继承并扩展了 SillyTavern 的功能
+- 添加了项目特色功能 (如 LOGIC 激活、RAG 配置、outputSchema 等)
+- 所有 API 响应、数据存储、工作流交换都使用这些模型
+- 无前缀,直接使用语义化名称
+
+**主要模型**:
+
+#### 世界书相关
+- `ActivationType` - 激活方式枚举 (PERMANENT/KEYWORD/RAG/LOGIC)
+- `LogicExpression` - 逻辑表达式
+- `RAGConfig` - RAG 检索配置
+- `WorldInfoEntry` - 世界书条目
+- `WorldInfo` - 世界书
+
+#### 角色卡相关
+- `OutputSchemaField` - 结构化输出 schema
+- `CharacterCard` - 角色卡
+
+#### 聊天记录相关
+- `ChatHeader` - 聊天头
+- `ChatMessage` - 聊天消息
+- `ChatLog` - 完整聊天记录
+
+#### 预设相关
+- `GenerationPreset` - 采样参数预设
+- `PromptRole` - Prompt 角色枚举
+- `PromptEntry` - Prompt 条目
+- `PromptPresetView` - Prompt 预设视图
+
+#### RAG 配置
+- `RAGSearchConfig` - RAG 搜索配置
+- `CharacterRAGConfig` - 角色卡 RAG 配置
+- `ChatRAGConfig` - 聊天 RAG 配置
+
+**使用场景**:
+```python
+# 业务逻辑中直接使用
+from models import CharacterCard, WorldInfo
+
+character = CharacterCard(
+    id="uuid-123",
+    name="Alice",
+    description="...",
+    ...
+)
+
+# API 响应
+@app.get("/characters/{id}")
+async def get_character(id: str):
+    character = service.get_character(id)
+    return character  # 返回 internal 模型
+```
+
+## 数据转换流程
+
+```
+SillyTavern 文件
+    ↓ (导入)
+STCharacterCard (sillytavern.py)
+    ↓ (转换器)
+CharacterCard (internal.py)
+    ↓ (业务处理)
+CharacterCard (internal.py)
+    ↓ (转换器)
+STCharacterCard (sillytavern.py)
+    ↓ (导出)
+SillyTavern 文件
+```
+
+## 开发规范
+
+### ✅ 正确做法
+
+1. **业务逻辑使用 internal 模型**
+   ```python
+   from models import CharacterCard
+   
+   def create_character(data: dict) -> CharacterCard:
+       return CharacterCard(**data)
+   ```
+
+2. **导入时使用转换器**
+   ```python
+   from models import STCharacterCard, CharacterCard
+   from models.converters import CharacterConverter
+   
+   def import_character(file_path: str) -> CharacterCard:
+       st_data = load_json(file_path)
+       st_char = STCharacterCard(**st_data)
+       return CharacterConverter.st_to_internal(st_char)
+   ```
+
+3. **API 响应使用 internal 模型**
+   ```python
+   @app.get("/characters")
+   async def list_characters() -> List[CharacterCard]:
+       return service.list_characters()
+   ```
+
+### ❌ 错误做法
+
+1. **不要在业务逻辑中直接使用 ST 模型**
+   ```python
+   # 错误!
+   from models import STCharacterCard
+   
+   def process_character(char: STCharacterCard):
+       ...
+   ```
+
+2. **不要混合使用两种模型**
+   ```python
+   # 错误!
+   character = CharacterCard(...)
+   character.name = st_character.data.name  # 不要混用
+   ```
+
+3. **不要在 API 中暴露 ST 模型**
+   ```python
+   # 错误!
+   @app.get("/characters")
+   async def list_characters() -> List[STCharacterCard]:
+       ...
+   ```
+
+## 添加新模型
+
+当需要添加新的数据类型时:
+
+1. **判断用途**:
+   - 如果是为了 SillyTavern 兼容 → 添加到 `sillytavern.py`
+   - 如果是项目内部使用 → 添加到 `internal.py`
+
+2. **遵循命名规范**:
+   - SillyTavern 模型: 前缀 `ST`
+   - 内部模型: 无前缀,使用清晰的语义化名称
+
+3. **添加详细注释**:
+   ```python
+   class MyModel(BaseModel):
+       """
+       模型用途说明
+       
+       详细描述该模型的作用、使用场景等
+       """
+       field1: str = Field(..., description="字段说明")
+   ```
+
+4. **在 `__init__.py` 中导出**:
+   ```python
+   from .internal import MyModel
+   
+   __all__ = [
+       ...,
+       'MyModel',
+   ]
+   ```
+
+## 转换器 (待实现)
+
+`models/converters.py` 将提供双向转换功能:
+
+```python
+class CharacterConverter:
+    @staticmethod
+    def st_to_internal(st_char: STCharacterCard) -> CharacterCard:
+        """SillyTavern → Internal"""
+        ...
+    
+    @staticmethod
+    def internal_to_st(int_char: CharacterCard) -> STCharacterCard:
+        """Internal → SillyTavern"""
+        ...
+```
+
+## 总结
+
+- **sillytavern.py** = 外部兼容层 (Import/Export Only)
+- **internal.py** = 内部业务层 (Core Business Logic)
+- **永远在业务逻辑中使用 internal 模型**
+- **通过转换器进行格式转换**

+# Z-Index 层级规范文档
+
+## 📋 概述
+
+本文档定义了项目中所有 z-index 的使用规范，确保层级关系清晰、一致、可维护。
+
+## 🎯 设计原则
+
+1. **分层管理**：将 z-index 划分为 5 个主要层级，每层预留充足空间
+2. **语义化命名**：使用有意义的变量名，而非魔法数字
+3. **统一来源**：所有 z-index 值统一定义在 `z-index.css` 中
+4. **易于扩展**：每层之间至少预留 100 的空间，方便插入新层级
+
+## 📊 层级划分
+
+### 1️⃣ 基础层 (0-99)
+用于页面背景、基础布局等底层元素
+
+| 变量名 | 值 | 用途 |
+|--------|-----|------|
+| `--z-background` | 0 | 最底层 - 背景装饰 |
+| `--z-base-content` | 1 | 基础内容层 - 普通文本、图片 |
+| `--z-divider` | 10 | 分割线、边框装饰 |
+
+**使用场景：**
+- 页面背景渐变
+- 基础卡片容器
+- 列表项默认状态
+
+---
+
+### 2️⃣ 组件层 (100-999)
+用于常规 UI 组件，如下拉菜单、悬浮提示等
+
+| 变量名 | 值 | 用途 |
+|--------|-----|------|
+| `--z-top-bar` | 100 | TopBar 导航栏 |
+| `--z-sidebar` | 100 | 侧边栏容器 |
+| `--z-dropdown-menu` | 1000 | 下拉菜单（预设操作、世界书选择） |
+| `--z-sort-panel` | 1100 | 排序设置面板 |
+| `--z-tooltip` | 1200 | 悬浮提示 Tooltip |
+| `--z-chat-actions` | 1000 | 聊天消息操作按钮 |
+| `--z-character-preview` | 1000 | 角色卡预览弹窗 |
+
+**使用场景：**
+- 点击按钮弹出的下拉菜单
+- 鼠标悬停显示的提示信息
+- 聊天消息的快捷操作按钮
+
+---
+
+### 3️⃣ 弹窗层 (10000-19999)
+用于模态对话框、编辑面板等需要覆盖整个页面的元素
+
+| 变量名 | 值 | 用途 |
+|--------|-------|------|
+| `--z-modal-overlay` | 10000 | 对话框遮罩层背景 |

+- 警告信息
+
+---
+
+### 5️⃣ 系统层 (30000+)
+用于系统级元素，如加载动画、错误边界等
+
+| 变量名 | 值 | 用途 |
+|--------|-------|------|
+| `--z-loading-spinner` | 30000 | 全局加载动画 |
+| `--z-error-boundary` | 30100 | 错误边界覆盖层 |

+
+## 💡 使用指南
+
+### CSS 中使用
+
+```css
+/* ✅ 推荐：使用 CSS 变量 */
+.dropdown-menu {
+  z-index: var(--z-dropdown-menu);
+}
+
+.modal-overlay {
+  z-index: var(--z-modal-overlay);
+}
+
+.edit-panel {
+  z-index: var(--z-edit-panel-content);
+}
+```
+
+### TypeScript/JavaScript 中使用
+
+```typescript
+// ✅ 推荐：导入常量
+import { Z_INDEX } from '../styles/z-index';
+
+const style = {
+  zIndex: Z_INDEX.DROPDOWN_MENU,
+};
+```
+
+### ❌ 避免的做法
+
+```css
+/* ❌ 不要使用魔法数字 */
+.dropdown-menu {
+  z-index: 1000;  /* 难以理解，不易维护 */
+}
+
+/* ❌ 不要使用过大的数值 */
+.modal {
+  z-index: 99999;  /* 不合理，可能导致层级混乱 */
+}
+```
+
+---
+
+## 🔧 添加新层级
+
+如果需要添加新的 z-index 层级，请遵循以下步骤：
+
+1. **确定所属层级**：根据元素类型选择合适的层级范围
+2. **选择合适数值**：在该层级范围内选择一个未使用的值（预留 100 间隔）
+3. **更新定义文件**：
+   - 在 `z-index.css` 中添加 CSS 变量
+   - 在 `z-index.ts` 中添加 TypeScript 常量
+4. **更新文档**：在本文档中添加说明
+
+**示例：添加一个新的工具提示层级**
+
+```css
+/* z-index.css */
+:root {
+  --z-help-tooltip: 1300;  /* 在 tooltip (1200) 之上 */
+}
+```
+
+```typescript
+// z-index.ts
+export const Z_INDEX = {
+  // ...
+  HELP_TOOLTIP: 1300,
+} as const;
+```
+
+---
+
+## 📝 常见问题
+
+### Q: 为什么弹窗层从 10000 开始？
+A: 为了与组件层（100-999）保持足够的距离，避免未来在组件层添加更多层级时产生冲突。
+
+### Q: 如果两个元素都需要弹窗层怎么办？
+A: 使用不同的子层级，例如：
+- 第一个弹窗：`--z-modal-content` (10100)
+- 第二个弹窗：`--z-modal-content + 10` (10110)
+
+### Q: 可以在 inline style 中使用吗？
+A: 可以，但推荐使用 CSS 类。如果必须使用 inline style：
+
+```jsx
+<div style={{ zIndex: 'var(--z-dropdown-menu)' }}>
+```
