+# 🎭 MADF: Multi-Agent Discussion Framework
+
+> **让思想在代码中碰撞，让灵魂在字节间共鸣。**
+
+---
+
+### 🌟 想象一下...
+
+想象一下，你置身于一个跨越时空的圆桌会议室。
+
+左手边，**苏格拉底**正抚须沉思，准备用反诘法拆解看似坚固的真理；右手边，**埃隆·马斯克**正激动地挥舞着双手，描绘着火星殖民的宏伟蓝图；而坐在对面的，或许是**孔子**，正温和地阐述着“仁”的治世之道。
+
+他们不再是冰冷的历史符号，也不是只会机械问答的搜索引擎。在这个框架中，他们拥有了**记忆**，拥有了**性格**，甚至拥有了**偏见**。他们会争论，会妥协，会因为观点的共鸣而激动，也会因为理念的冲突而愤怒。
+
+这不是科幻小说，这是 **MADF (Multi-Agent Discussion Framework)** 为你呈现的数字现实。
+
+我们构建的不仅仅是一个聊天室，而是一个**思想的培养皿**。在这里，你可以：
+*   观察不同流派的哲学如何交锋；
+*   模拟复杂的社会决策过程；
+*   甚至仅仅是享受一场高质量的、充满意外的智力狂欢。
+
+---
+
+### 🎯 项目核心
+
+MADF 是一个基于 [HelloAgents](https://github.com/jjyaoao/helloagents) 的**沉浸式多智能体圆桌讨论应用**。它使用 HelloAgents 创建并驱动主持人、嘉宾和角色生成智能体，在应用层保留圆桌调度、双层记忆与实时 WebSocket 交互。
+
+*   **🧠 深度角色生成 (RealGod Agent)**: 基于 ReAct 框架，智能体能够主动搜索互联网，学习真实人物的生平、理论与性格，拒绝脸谱化的 NPC。
+*   **💾 双层记忆系统**: 
+    *   **私有记忆**: 智能体拥有内心独白，能记住自己的思考过程，避免“复读机”式的发言。
+    *   **共享记忆**: 所有参与者共享讨论上下文，确保对话的连贯性与针对性。
+*   **🎤 动态主持机制**: 引入主持人（Moderator）角色，负责控场、总结与推进议题，防止讨论发散或陷入死循环。
+*   **📊 多维评估体系**: 独创的 5 维评估指标（观点多样性、深度演进、交互批判性等），量化讨论质量。
+
+---
+
+### 🏗️ 系统架构介绍
+
+MADF 采用 **现代化的前后端分离架构**，后端基于 Python 异步生态构建高性能调度中心，前端采用 Vue 3 打造沉浸式交互体验，通过 WebSocket 实现毫秒级的双向流式通信。

+
+#### 2. 逐层解析
+
+**🖥️ 前端层 (Frontend)**
+- **技术栈**: Vue 3 (Composition API), Vite, TypeScript, Pinia, Ant Design Vue。
+- **核心职责**:
+    - **流式渲染**: 通过 `useForumWebSocket` 钩子实时接收后端 Token 流，实现“打字机”效果。
+    - **状态管理**: 利用 Pinia 管理全局的用户会话、论坛列表及当前对话上下文。
+    - **路由与权限**: Vue Router 配合导航守卫，实现基于 JWT 的登录拦截与页面跳转。
+
+**⚙️ 后端层 (Backend)**
+- **技术栈**: Python 3.10+, HelloAgents 1.0.0, FastAPI, Uvicorn, Pydantic。
+- **核心模块**:
+    - **API 网关**: 处理 HTTP 请求（如创建论坛、查询历史），集成 CORS 与 JWT 鉴权中间件。
+    - **论坛调度器 (ForumScheduler)**: 系统的“心脏”，基于 `asyncio` 维护全局事件循环，管理多个智能体的并发思考、发言队列及时间片轮转。
+    - **智能体运行时**: 主持人与嘉宾直接继承 HelloAgents `SimpleAgent`，由 `HelloAgentsLLM`、`run()`、`stream_run()`、`add_message()` 和框架历史管理完成推理、流式输出与上下文恢复。
+    - **角色生成智能体**: `RealGodAgent` 使用 HelloAgents `ReActAgent`、`ToolRegistry` 与标准 `Tool` 接口调用 StepSearch MCP，生成前执行点名人物一致性校验。
+- **通信协议**:
+    - **HTTP (REST)**: 用于元数据管理（User, Forum, Persona）。
+    - **WebSocket**: 用于实时传输对话内容、系统日志及控制信号。
+
+**💾 数据层 (Data Layer)**
+- **数据库**:
+    - **SQLite (默认)**: 采用 `libsql-client`，零配置启动，适合开发与中小规模部署。
+    - **PostgreSQL (实验性)**: 代码包含适配层，但当前 schema 初始化与 CI 门禁以 SQLite 为准；生产使用前需自行完成迁移验证。
+- **缓存/消息队列**:
+    - **Redis (可选)**: 用于存储系统日志缓冲 (System Logs Buffer) 和高频状态同步。
+
+**🏗️ 基础设施 (Infrastructure)**
+- **容器化**: 提供标准 `Dockerfile`，支持多阶段构建 (Multi-stage Build)，最小化镜像体积。
+- **编排**: `docker-compose.yml` 一键拉起前后端及依赖服务。
+- **质量门禁**: 提供 Pytest、Vitest、类型检查、前端生产构建与 Docker 构建命令，便于提交前在本地或外部 CI 中复现验证。
+
+#### 3. 关键非功能特性
+- **实时性**: WebSocket 按 token 流式推送论坛消息；实际延迟和并发能力取决于模型服务、网络与部署资源。
+- **可用性**: SQLite 写入包含锁冲突重试，模型调用由 HelloAgents 统一设置超时；生产部署仍应配置外部监控和限流。
+- **扩展性**: 新角色可直接继承 HelloAgents `SimpleAgent`，复用 MADF 的论坛编排协议或注册新的 HelloAgents Tool。
+- **安全**: 生产环境强制开启 JWT 认证；敏感密钥 (API Key) 仅在服务端存储，不暴露给前端。
+
+
+### 🚀 快速启动
+
+MADF 提供了灵活的启动方式，既支持 **Docker 一键部署**（推荐），也支持 **本地源码开发**。
+
+#### 前置要求
+- **操作系统**: Windows 10+ / macOS / Linux
+- **依赖环境**:
+  - Python 3.10+
+  - Node.js 20+ (仅源码开发需要)
+  - Docker & Docker Compose (仅容器化部署需要)
+- **API 密钥**: 必须持有 StepFun API Key，并开通 Step Plan 模型与 StepSearch MCP 能力。
+
+---
+
+#### 1. 配置环境变量 (所有方式通用)
+
+在项目根目录下复制配置文件并填入密钥：
+
+```bash
+# 复制示例配置
+cp .env.example .env
+```
+
+编辑 `.env` 文件，填入你的 API Key：
+
+```ini
+# HelloAgents / StepFun configuration
+API_KEY="your_api_key_here"
+MODEL_NAME="step-3.7-flash"
+BASE_URL=https://api.stepfun.com/step_plan/v1/
+```
+
+> **注意**: 
+> 1. `BASE_URL` 必须以 `https://` 开头并以 `/` 结尾。
+> 2. 角色生成通过 HelloAgents Tool 调用 StepSearch MCP，模型与搜索复用同一个 StepFun Key。
+
+---
+
+#### 2. 方式一：Docker Compose 一键启动 (推荐)
+
+Compose 会从当前工作树构建镜像，确保运行内容与待审阅代码一致。
+
+**一键部署命令**
+
+您可以直接下载我们准备好的 `docker-compose.yml` 文件并启动：
+
+```bash
+# 在项目根目录配置 .env 后构建并启动
+docker compose up --build -d
+```
+
+**配置说明**
+
+请在 `.env` 中配置至少以下变量：
+
+```yaml
+API_KEY=your_real_api_key_here
+MODEL_NAME=step-3.7-flash
+BASE_URL=https://api.stepfun.com/step_plan/v1/
+SECRET_KEY=replace-with-a-long-random-secret
+```
+
+- **访问地址**: `http://localhost:8000`
+- **查看日志**: `docker-compose logs -f`
+- **停止服务**: `docker-compose down`
+
+#### 3. 方式二：本地源码启动 (开发模式)
+
+适合需要修改代码的开发者。
+
+**步骤 A: 启动后端 (Python/FastAPI)**
+
+```bash
+# 1. 创建并激活虚拟环境
+python -m venv .venv
+# Windows:
+.venv\Scripts\activate
+# Mac/Linux:
+source .venv/bin/activate
+
+# 2. 安装依赖
+pip install -r requirements.txt
+
+# 3. 初始化数据库 (首次运行需要)
+# 系统会自动在 data/madf.db 创建表结构
+
+# 4. 启动服务 (开启热重载)
+uvicorn app.main:app --reload --host 0.0.0.0 --port 8000
+```
+
+后端启动后，创建论坛并启动讨论。主持人开场、至少一位嘉宾思考并发言、主持人总结，即构成一次端到端 HelloAgents 多智能体流程。
+
+可先运行框架迁移相关测试：
+
+```bash
+pytest app/tests/test_helloagents_integration.py app/tests/test_agent_logic.py -q
+```
+
+也可以不启动数据库和前端，直接运行最小端到端讨论：
+
+```bash
+python demo_helloagents.py
+```
+
+该示例依次执行主持人开场、嘉宾思考与发言、阶段总结和闭幕，所有模型调用均由 HelloAgents 1.0.0 驱动。
+
+共创项目的标准脚本入口同样可用：
+
+```bash
+python main.py
+```
+
+仓库还提供 `main.ipynb`，用于按毕业设计模板逐步展示 HelloAgents 原生 Agent、流式讨论和最终转录结果。
+
+**步骤 B: 启动前端 (Vue 3/Vite)**
+
+```bash
+cd frontend
+
+# 1. 安装依赖
+npm ci
+
+# 2. 启动开发服务器
+npm run dev
+```
+
+- **前端访问**: `http://localhost:5173`
+- **后端 API**: `http://localhost:8000`
+
+> **注意**: 在开发模式下，前端 Vite 服务器会通过代理 (Proxy) 将 API 请求转发到后端 8000 端口，请确保后端已启动。
+
+---
+
+#### 4. 常见问题 (FAQ)
+
+- **Q: 启动后角色生成缓慢？**
+  - A: `ReActAgent` 会通过 StepSearch MCP 检索并核实人物资料，首次生成通常需要多轮模型与搜索请求。
+- **Q: WebSocket 连接失败？**
+  - A: 请确保没有防火墙或代理软件拦截 `ws://localhost:8000` 的连接。
+

+# 1. 选用 FastAPI 作为后端框架
+
+日期: 2026-03-09
+
+## 状态
+
+已采纳
+
+## 背景
+
+我们需要构建一个高性能、易于维护且能良好支持 AI/LLM 生态的后端服务。备选方案包括 Django (Python), Flask (Python), Express/NestJS (Node.js), Gin (Go)。
+
+## 决策
+
+选择 **FastAPI** (Python)。
+
+## 理由
+
+1.  **原生异步支持 (AsyncIO)**: 多智能体系统涉及大量 I/O 密集型任务（如调用 LLM API、WebSocket 推送），FastAPI 的异步特性通过 `async/await` 能显著提高并发处理能力。
+2.  **AI 生态亲和力**: Python 是 AI/ML 领域的首选语言。使用 Python 作为后端可以直接集成 HelloAgents、StepFun 与 MCP 工具，无需跨语言调用。
+3.  **开发效率与类型安全**: 基于 Pydantic 的类型提示提供了自动的数据验证和文档生成 (Swagger UI)，大幅降低了前后端联调成本。
+4.  **性能**: 在 Python web 框架中，FastAPI 的性能仅次于 Starlette，足以满足本系统的实时性需求。
+
+## 后果
+
+- 需要团队熟悉 Python 的异步编程模式。
+- 相比 Go/Java，Python 的 CPU 密集型计算能力较弱，但本系统主要是 I/O 密集型，影响有限。

+# 2. 选用 Vue 3 + Vite 作为前端技术栈
+
+日期: 2026-03-09
+
+## 状态
+
+已采纳
+
+## 背景
+
+前端需要一个响应迅速、开发体验良好且易于构建复杂交互界面（如流式对话、动态仪表盘）的框架。备选方案包括 React, Vue 2, Angular。
+
+## 决策
+
+选择 **Vue 3** 配合 **Vite** 构建工具。
+
+## 理由
+
+1.  **响应式系统 (Reactivity)**: Vue 3 的 Proxy 机制和 Composition API 非常适合处理 WebSocket 推送的高频数据更新（如打字机效果），且代码组织更具逻辑性。
+2.  **构建性能**: Vite 基于 ES Modules，提供了极速的热更新 (HMR) 和冷启动体验，显著提升开发效率。
+3.  **生态整合**: 配合 Pinia (状态管理) 和 Vue Router，以及 Ant Design Vue 组件库，能够快速搭建美观且功能完备的管理后台与聊天界面。
+4.  **学习曲线**: 相比 React 的 Hooks 心智负担，Vue 3 更符合直觉，利于团队快速上手。
+
+## 后果
+
+- 需要确保第三方库对 Vue 3 的兼容性（目前已非常成熟）。
+- 需遵循 Composition API 的最佳实践，避免逻辑混乱。

+# 3. 选用 SQLite 作为默认数据库
+
+日期: 2026-03-09
+
+## 状态
+
+已采纳
+
+## 背景
+
+MADF 系统需要存储用户信息、论坛配置、对话历史等结构化数据。考虑到项目初期部署的便捷性以及未来可能的扩展需求。备选方案包括 PostgreSQL, MySQL, SQLite。
+
+## 决策
+
+选择 **SQLite** 作为默认开发与单机部署数据库，同时保留 **PostgreSQL** 兼容性。
+
+## 理由
+
+1.  **零配置 (Zero-Configuration)**: SQLite 是基于文件的数据库，无需安装额外的服务器进程，极大地简化了本地开发和 Docker 部署流程（只需挂载一个文件）。
+2.  **足以应付中小规模**: 对于圆桌论坛这种读写并发量中等的应用，现代 SQLite (配合 WAL 模式) 的性能完全足够。
+3.  **LibSQL 兼容**: 项目使用 `libsql-client`，支持无缝迁移到 Turso 等边缘数据库，兼顾了本地开发的便捷与云端扩展的潜力。
+4.  **数据一致性**: 支持 ACID 事务，确保多智能体并发写入时的数据完整性。
+
+## 后果
+
+- 无法利用 PostgreSQL 的一些高级特性（如复杂的 JSONB 查询优化、向量插件 pgvector），需在应用层处理或后续迁移。
+- 垂直扩展受限，但通过应用层设计（如 Redis 缓冲）可缓解。
