+# 智保通后端
+
+本目录是智保通的统一后端，使用 Python 3.12 和 FastAPI 开发，负责 API、
+业务规则、身份认证及数据库访问。
+
+## 技术栈
+
+- Python 3.12
+- FastAPI、Pydantic
+- SQLAlchemy、Alembic
+- LangChain 1.x、DeepSeek、LangSmith
+- MySQL 8、Redis
+- uv（依赖与虚拟环境管理）
+- pytest、Ruff、mypy（测试与代码检查）
+
+项目使用 `pyproject.toml` 和 `uv.lock` 管理依赖，不使用
+`requirements.txt`、Poetry 或 Conda。
+
+## 目录结构
+
+```text
+backend/
+├── src/
+│   └── zbt/               # 可安装的智保通 Python 包
+│       ├── api/           # HTTP 路由、请求参数和响应格式
+│       ├── commands/      # 初始化数据等命令行工具
+│       ├── core/          # 配置、安全、密码和公共错误
+│       ├── domains/       # 业务模型、仓储接口和业务服务
+│       ├── harness/       # Agent 内核、策略和资源
+│       ├── infrastructure/# MySQL、Redis、Milvus 等基础设施实现
+│       └── main.py        # FastAPI 应用入口
+├── migrations/            # 三个数据库的 Alembic 迁移
+├── tests/                 # 自动化测试
+├── alembic.ini
+├── pyproject.toml
+└── uv.lock
+```
+
+项目采用 `src` 布局，`uv sync` 会以可编辑模式安装 `zbt` 包；执行
+`uv build` 可以生成 wheel 和源码包。
+
+代码主要调用方向：
+
+```text
+HTTP 请求 → api 路由 → domain service → repository → MySQL
+```
+
+AI Agent 的主要调用方向：
+
+```text
+Agent API → Agent service → LangChain create_agent
+          → DeepSeek（OpenAI 兼容接口）→ 产品目录 Tool
+          → Agent MySQL 持久化 + LangSmith Trace
+```
+
+## 环境配置
+
+后端读取当前 `backend` 目录中的 `.env`。
+
+首次使用时，在 `backend` 目录创建并配置 `.env`：
+
+```powershell
+notepad .env
+```
+
+常用配置包括：
+
+- `MYSQL_HOST`、`MYSQL_PORT`：MySQL 地址和端口
+- `MYSQL_USER`、`MYSQL_PASSWORD`：后端数据库账号
+- `REDIS_URL`：Redis 连接地址
+- `JWT_ACCESS_SECRET`、`JWT_REFRESH_SECRET`：登录令牌密钥
+- `DEV_FIXED_OTP`：开发环境固定验证码
+- `DEEPSEEK_API_KEY`、`DEEPSEEK_BASE_URL`、`DEEPSEEK_MODEL`：模型配置
+- `LANGSMITH_API_KEY`、`LANGSMITH_ENDPOINT`、`LANGSMITH_PROJECT`、
+  `LANGSMITH_TRACING`：Agent 链路追踪配置
+- `MOCK_PAYMENT_CALLBACK_SECRET`：本地模拟支付回调的 HMAC 签名密钥
+
+不要把包含真实密码和密钥的 `.env` 提交到 Git。
+
+## 安装后端依赖
+
+```powershell
+Set-Location backend
+uv sync --locked
+```
+
+`uv sync --locked` 会按照 `uv.lock` 创建或更新 `.venv`，确保每台电脑安装
+相同版本的依赖。
+
+## 初始化数据库
+
+请先启动 MySQL 8 和 Redis，然后在项目根目录执行：
+
+```powershell
+.\scripts\check-env.ps1
+.\scripts\init-databases.ps1
+.\scripts\migrate.ps1
+.\scripts\inherit-stage-one.ps1
+.\scripts\seed.ps1
+.\scripts\build-analytics.ps1
+.\scripts\verify-seed.ps1
+```
+
+这些脚本依次完成环境检查、创建数据库、建表、继承第一阶段持久化数据、
+写入第二阶段初始数据、构建分析数据和验证初始化结果。
+
+## 单独启动后端
+
+```powershell
+Set-Location backend
+uv run uvicorn zbt.main:app --reload --host 127.0.0.1 --port 8000
+```
+
+启动后访问：
+
+- API 文档：<http://127.0.0.1:8000/docs>
+- OpenAPI JSON：<http://127.0.0.1:8000/openapi.json>
+- 健康检查：<http://127.0.0.1:8000/api/v1/system/health/live>
+
+按 `Ctrl + C` 停止后端。
+
+## 测试和代码检查
+
+在 `backend` 目录执行：
+
+```powershell
+uv run pytest
+uv run ruff check .
+uv run mypy src/zbt
+```
+
+也可以在项目根目录执行 `.\scripts\test.ps1`，同时检查前端和后端。
+
+## 数据库迁移
+
+项目使用三个相互独立的数据库：
+
+- `insurance_s2_core`
+- `insurance_s2_agent`
+- `insurance_s2_analytics`
+
+需要手动执行迁移时，在 `backend` 目录运行：
+
+```powershell
+uv run alembic -c alembic.ini --name alembic_core upgrade head
+uv run alembic -c alembic.ini --name alembic_agent upgrade head
+uv run alembic -c alembic.ini --name alembic_analytics upgrade head
+```
+
+已经发布的迁移文件不要直接修改；表结构发生变化时应新增 revision。
