+## 🏗️ Phase 1: 基础设施搭建（已完成）
+
+### 架构概览
+
+Phase 1 完成了项目的基础设施搭建，包括：
+- ✅ 数据持久化层（MySQL + JPA + Flyway）
+- ✅ 会话管理（Redis）
+- ✅ 向量索引（Milvus 集成）
+- ✅ 文档管理服务（上传/查询/删除）
+- ✅ 统一异常处理
+- ✅ RESTful API 接口
+
+### 本地开发环境
+
+#### 前置要求
+
+- Java 17+
+- Maven 3.8+
+- Docker & Docker Compose（用于本地数据库）
+
+#### 快速开始
+
+**1. 启动依赖服务**
+
+```bash
+# 启动 MySQL + Redis + Milvus（本地开发）
+docker-compose up -d
+
+# 查看服务状态
+docker-compose ps
+```
+
+**2. 配置应用**
+
+复制 `src/main/resources/application.yml` 并根据需要修改：
+
+```yaml
+spring:
+  datasource:
+    url: jdbc:mysql://localhost:3306/super_biz_agent
+    username: superbiz
+    password: superbiz123
+  
+  data:
+    redis:
+      host: localhost
+      port: 6379
+      password: redis123
+
+milvus:
+  host: localhost
+  port: 19530
+```
+
+**3. 运行应用**
+
+```bash
+# 编译
+mvn clean compile
+
+# 运行测试
+mvn test
+
+# 启动应用
+mvn spring-boot:run
+```
+
+应用将在 `http://localhost:9900` 启动。
+
+#### 数据库迁移
+
+Flyway 会自动执行数据库迁移：
+
+```
+src/main/resources/db/migration/
+├── V001__create_diagnosis_record.sql
+├── V002__create_case_library.sql
+└── V003__create_api_document.sql
+```
+
+#### API 文档
+
+**文档管理接口**：
+
+```bash
+# 上传文档（仅支持 .md 和 .txt）
+POST /api/documents/upload
+Content-Type: multipart/form-data
+
+# 查询文档
+GET /api/documents/{docId}
+GET /api/documents/status/{status}?page=0&size=20
+GET /api/documents/faultSource/{faultSource}
+
+# 删除文档
+DELETE /api/documents/{docId}
+```
+
+**健康检查**：
+
+```bash
+# Milvus 连接测试
+mvn test -Dtest=SimpleMilvusTest
+
+# MySQL 连接测试
+mvn test -Dtest=MySQLConnectionTest
+
+# Redis 连接测试
+mvn test -Dtest=RedisConnectionTest
+```
+

+
+### 待办事项
+
+- [ ] 向量化索引实现（VectorIndexService.indexDocumentChunks）
+- [ ] 混合检索工具（精确匹配 + 语义检索 + RRF 融合）
+- [ ] 文档管理集成测试
+
+### 技术决策
+
+- **包名重构**：`org.example` → `com.superbiz.agent`
+- **文本格式**：仅支持 Markdown (.md) 和纯文本 (.txt)，其他格式需外部转换服务
+- **分块策略**：使用 DocumentChunkService 的智能分块（按标题、段落边界）
+- **向量数据库**：生产环境推荐 Zilliz Cloud，本地开发可用 Docker Milvus
