+# TJWater Server - Copilot Instructions
+
+This is a FastAPI-based water network management system (供水管网智能管理系统) that provides hydraulic simulation, SCADA data integration, network element management, and risk analysis capabilities.
+
+## Running the Server
+
+```bash
+# Install dependencies
+pip install -r requirements.txt
+
+# Start the server (default: http://0.0.0.0:8000 with 2 workers)
+python scripts/run_server.py
+
+# Note: On Windows, the script automatically sets WindowsSelectorEventLoopPolicy
+```
+
+## Running Tests
+
+```bash
+# Run all tests
+pytest
+
+# Run a specific test file with verbose output
+pytest tests/unit/test_pipeline_health_analyzer.py -v
+
+# Run from conftest helper
+python tests/conftest.py
+```
+
+## Architecture Overview
+
+### Core Components
+
+1. **Native Modules** (`app/native/`): Platform-specific compiled extensions (`.so` for Linux, `.pyd` for Windows) providing performance-critical functionality including:
+   - SCADA device integration
+   - Water distribution analysis (WDA)
+   - Pipe risk probability calculations
+   - Wrapped through `app.services.tjnetwork` interface
+
+2. **Services Layer** (`app/services/`):
+   - `tjnetwork.py`: Main network API wrapper around native modules
+   - `simulation.py`: Hydraulic simulation orchestration (EPANET integration)
+   - `project_info.py`: Project configuration management
+   - `epanet/`: EPANET hydraulic engine integration
+
+3. **API Layer** (`app/api/v1/`):
+   - **Network Elements**: Separate endpoint modules for junctions, reservoirs, tanks, pipes, pumps, valves
+   - **Components**: Curves, patterns, controls, options, quality, visuals
+   - **Network Features**: Tags, demands, geometry, regions/DMAs
+   - **Core Services**: Auth, project, simulation, SCADA, data query, snapshots
+
+4. **Database Infrastructure** (`app/infra/db/`):
+   - **PostgreSQL**: Primary relational database (users, audit logs, project metadata)
+   - **TimescaleDB**: Time-series extension for historical data
+   - **InfluxDB**: Optional time-series database for high-frequency SCADA data
+   - Connection pools initialized in `main.py` lifespan context
+   - Database instance stored in `app.state.db` for dependency injection
+
+5. **Domain Layer** (`app/domain/`):
+   - `models/`: Enums and domain objects (e.g., `UserRole`)
+   - `schemas/`: Pydantic models for request/response validation
+
+6. **Algorithms** (`app/algorithms/`):
+   - `api_ex/`: Analysis algorithms (k-means sensor placement, sensitivity analysis, pipeline health)
+   - `data_cleaning.py`: Data preprocessing utilities
+   - `simulations.py`: Simulation helpers
+
+### Security & Authentication
+
+- **Authentication**: JWT-based with access tokens (30 min) and refresh tokens (7 days)
+- **Authorization**: Role-based access control (RBAC) with 4 roles:
+  - `VIEWER`: Read-only access
+  - `USER`: Read-write access
+  - `OPERATOR`: Modify data
+  - `ADMIN`: Full permissions
+- **Audit Logging**: `AuditMiddleware` automatically logs POST/PUT/DELETE requests
+- **Encryption**: Fernet symmetric encryption for sensitive data (`app.core.encryption`)
+
+Default admin accounts:
+- `admin` / `admin123`
+- `tjwater` / `tjwater@123`
+
+### Key Files
+
+- `app/main.py`: FastAPI app initialization, lifespan (DB pools), CORS, middleware, router mounting
+- `app/api/v1/router.py`: Central router aggregating all endpoint modules
+- `app/core/config.py`: Settings management using `pydantic-settings`
+- `app/auth/dependencies.py`: Auth dependencies (`get_current_active_user`, `get_db`)
+- `app/auth/permissions.py`: Permission decorators (`require_role`, `get_current_admin`)
+- `.env`: Environment configuration (database credentials, JWT secret, encryption key)
+
+## Important Conventions
+
+### Database Connections
+
+- Database instances are initialized in `main.py` lifespan and stored in `app.state.db`
+- Access via dependency injection:
+  ```python
+  from app.auth.dependencies import get_db
+  
+  async def endpoint(db = Depends(get_db)):
+      # Use db connection
+  ```
+
+### Authentication in Endpoints
+
+Use dependency injection for auth requirements:
+
+```python
+from app.auth.dependencies import get_current_active_user
+from app.auth.permissions import require_role, get_current_admin
+from app.domain.models.role import UserRole
+
+# Require any authenticated user
+@router.get("/data")
+async def get_data(current_user = Depends(get_current_active_user)):
+    return data
+
+# Require specific role (USER or higher)
+@router.post("/data")
+async def create_data(current_user = Depends(require_role(UserRole.USER))):
+    return result
+
+# Admin-only access
+@router.delete("/data/{id}")
+async def delete_data(id: int, current_user = Depends(get_current_admin)):
+    return result
+```
+
+### API Routing Structure
+
+- All v1 APIs are mounted under `/api/v1` prefix via `api_router`
+- Legacy routes without version prefix are also mounted for backward compatibility
+- Group related endpoints in separate router modules under `app/api/v1/endpoints/`
+- Use descriptive tags in `router.py` for OpenAPI documentation grouping
+
+### Native Module Integration
+
+- Native modules are pre-compiled for specific platforms
+- Always import through `app.native.api` or `app.services.tjnetwork`
+- The `tjnetwork` service wraps native APIs with constants like:
+  - Element types: `JUNCTION`, `RESERVOIR`, `TANK`, `PIPE`, `PUMP`, `VALVE`
+  - Operations: `API_ADD`, `API_UPDATE`, `API_DELETE`
+  - `ChangeSet` for batch operations
+
+### Project Initialization
+
+- On startup, `main.py` automatically loads project from `project_info.name` if set
+- Projects are opened via `open_project(name)` from `tjnetwork` service
+
+### Audit Logging
+
+Manual audit logging for critical operations:
+
+```python
+from app.core.audit import log_audit_event, AuditAction
+
+await log_audit_event(
+    action=AuditAction.UPDATE,
+    user_id=current_user.id,
+    username=current_user.username,
+    resource_type="resource_name",
+    resource_id=str(resource_id),
+    ip_address=request.client.host,
+    request_data=data
+)
+```
+
+### Environment Configuration
+
+- Copy `.env.example` to `.env` before first run
+- Required environment variables:
+  - `SECRET_KEY`: JWT signing (generate with `openssl rand -hex 32`)
+  - `ENCRYPTION_KEY`: Data encryption (generate with Fernet)
+  - Database credentials for PostgreSQL, TimescaleDB, and optionally InfluxDB
+
+### Database Migrations
+
+SQL migration scripts are in `migrations/`:
+- `001_create_users_table.sql`: User authentication tables
+- `002_create_audit_logs_table.sql`: Audit logging tables
+
+Apply with:
+```bash
+psql -U postgres -d tjwater -f migrations/001_create_users_table.sql
+```

+---
+
+## 🔧 集成步骤
+
+### 步骤 1: 环境配置
+
+1. 复制环境变量模板：
+```bash
+cp .env.example .env
+```
+
+2. 生成密钥并填写 `.env`：
+```bash
+# JWT 密钥
+openssl rand -hex 32
+
+# 加密密钥
+python -c "from cryptography.fernet import Fernet; print(Fernet.generate_key().decode())"
+```
+
+3. 编辑 `.env` 填写所有必需的配置项。
+
+### 步骤 2: 数据库迁移
+
+执行数据库迁移脚本：
+
+```bash
+# 方法 1: 使用 psql 命令
+psql -U postgres -d tjwater -f migrations/001_create_users_table.sql
+psql -U postgres -d tjwater -f migrations/002_create_audit_logs_table.sql
+
+# 方法 2: 在 psql 交互界面
+psql -U postgres -d tjwater
+\i migrations/001_create_users_table.sql
+\i migrations/002_create_audit_logs_table.sql
+```
+
+验证表已创建：
+
+```sql
+-- 检查用户表
+SELECT * FROM users;
+
+-- 检查审计日志表
+SELECT * FROM audit_logs;
+```
+
+### 步骤 3: 更新 main.py
+
+在 `app/main.py` 中集成新功能：
+
+```python
+from fastapi import FastAPI
+from app.core.config import settings
+from app.infra.audit.middleware import AuditMiddleware
+
+app = FastAPI(title=settings.PROJECT_NAME)
+
+# 1. 添加审计中间件（可选）
+app.add_middleware(AuditMiddleware)
+
+# 2. 注册路由
+from app.api.v1.endpoints import auth, user_management, audit
+
+app.include_router(
+    auth.router,
+    prefix=f"{settings.API_V1_STR}/auth",
+    tags=["认证"]
+)
+
+app.include_router(
+    user_management.router,
+    prefix=f"{settings.API_V1_STR}/users",
+    tags=["用户管理"]
+)
+
+app.include_router(
+    audit.router,
+    prefix=f"{settings.API_V1_STR}/audit",
+    tags=["审计日志"]
+)
+
+# 3. 确保数据库在启动时初始化
+@app.on_event("startup")
+async def startup_event():
+    # 初始化数据库连接池
+    from app.infra.db.postgresql.database import Database
+    global db
+    db = Database()
+    db.init_pool()
+    await db.open()
+
+@app.on_event("shutdown")
+async def shutdown_event():
+    # 关闭数据库连接
+    await db.close()
+```
+
+### 步骤 4: 保护现有接口
+
+#### 方法 1: 为路由添加全局依赖
+
+```python
+from app.auth.dependencies import get_current_active_user
+
+# 为整个路由器添加认证
+router = APIRouter(dependencies=[Depends(get_current_active_user)])
+```
+
+#### 方法 2: 为单个端点添加依赖
+
+```python
+from app.auth.permissions import require_role, get_current_admin
+from app.domain.models.role import UserRole
+
+@router.get("/data")
+async def get_data(
+    current_user = Depends(require_role(UserRole.USER))
+):
+    """需要 USER 及以上角色"""
+    return {"data": "protected"}
+
+@router.delete("/data/{id}")
+async def delete_data(
+    id: int,
+    current_user = Depends(get_current_admin)
+):
+    """仅管理员可访问"""
+    return {"message": "deleted"}
+```
+
+### 步骤 5: 添加审计日志
+
+#### 自动审计（推荐）
+
+使用中间件自动记录（已在 main.py 中添加）：
+
+```python
+app.add_middleware(AuditMiddleware)
+```
+
+#### 手动审计
+
+在关键业务逻辑中手动记录：
+
+```python
+from app.core.audit import log_audit_event, AuditAction
+
+@router.post("/important-action")
+async def important_action(
+    data: dict,
+    request: Request,
+    current_user = Depends(get_current_active_user)
+):
+    # 执行业务逻辑
+    result = do_something(data)
+    
+    # 记录审计日志
+    await log_audit_event(
+        action=AuditAction.UPDATE,
+        user_id=current_user.id,
+        username=current_user.username,
+        resource_type="important_resource",
+        resource_id=str(result.id),
+        ip_address=request.client.host,
+        request_data=data
+    )
+    
+    return result
+```
+
+### 步骤 6: 更新 auth/dependencies.py
+
+确保 `get_db()` 函数正确获取数据库实例：
+
+```python
+async def get_db() -> Database:
+    """获取数据库实例"""
+    # 方法 1: 从 main.py 导入
+    from app.main import db
+    return db
+    
+    # 方法 2: 从 FastAPI app.state 获取
+    # from fastapi import Request
+    # def get_db_from_request(request: Request):
+    #     return request.app.state.db
+```
+
+---
+
+## 🧪 测试
+
+### 1. 测试加密功能
+
+```bash
+python tests/test_encryption.py
+```
+
+### 2. 测试 API
+
+启动服务器：
+
+```bash
+uvicorn app.main:app --reload
+```
+
+访问交互式文档：
+- Swagger UI: http://localhost:8000/docs
+- ReDoc: http://localhost:8000/redoc
+
+### 3. 测试登录
+
+```bash
+curl -X POST "http://localhost:8000/api/v1/auth/login" \
+  -H "Content-Type: application/x-www-form-urlencoded" \
+  -d "username=admin&password=admin123"
+```
+
+### 4. 测试受保护接口
+
+```bash
+TOKEN="your-access-token"
+curl -X GET "http://localhost:8000/api/v1/auth/me" \
+  -H "Authorization: Bearer $TOKEN"
+```
+
+---
+
+## 🔄 迁移现有接口
+
+### 原有硬编码认证
+
+**旧代码** (`app/api/v1/endpoints/auth.py`):
+```python
+AUTH_TOKEN = "567e33c876a2"
+
+async def verify_token(authorization: str = Header()):
+    token = authorization.split(" ")[1]
+    if token != AUTH_TOKEN:
+        raise HTTPException(status_code=403)
+```
+
+**新代码** (已更新):
+```python
+from app.auth.dependencies import get_current_active_user
+
+@router.get("/protected")
+async def protected_route(
+    current_user = Depends(get_current_active_user)
+):
+    return {"user": current_user.username}
+```
+
+### 更新其他端点
+
+搜索项目中使用旧认证的地方：
+
+```bash
+grep -r "AUTH_TOKEN" app/
+grep -r "verify_token" app/
+```
+
+替换为新的依赖注入系统。
+
+---
+
+## 📋 检查清单
+
+部署前检查：
+
+- [ ] 环境变量已配置（`.env`）
+- [ ] 数据库迁移已执行
+- [ ] 默认管理员账号可登录
+- [ ] JWT Token 可正常生成和验证
+- [ ] 权限控制正常工作
+- [ ] 审计日志正常记录
+- [ ] 加密功能测试通过
+- [ ] API 文档可访问
+
+---
+
+## ⚠️ 注意事项
+
+### 1. 向后兼容性
+
+保留了简化版登录接口 `/auth/login/simple` 以兼容旧客户端：
+
+```python
+@router.post("/login/simple")
+async def login_simple(username: str, password: str):
+    # 验证并返回 Token
+    ...
+```
+
+### 2. 数据库连接
+
+确保在 `app/auth/dependencies.py` 中 `get_db()` 函数能正确获取数据库实例。
+
+### 3. 密钥安全
+
+- ❌ 不要提交 `.env` 文件到版本控制
+- ✅ 在生产环境使用环境变量或密钥管理服务
+- ✅ 定期轮换 JWT 密钥
+
+### 4. 性能考虑
+
+- 审计中间件会增加每个请求的处理时间（约 5-10ms）
+- 对高频接口可考虑异步记录审计日志
+- 定期清理或归档旧的审计日志
+
+---
+
+## 🐛 故障排查
+
+### 问题 1: 导入错误
+
+```
+ImportError: cannot import name 'db' from 'app.main'
+```
+
+**解决**: 确保在 `app/main.py` 中定义了全局 `db` 对象。
+
+### 问题 2: 认证失败
+
+```
+401 Unauthorized: Could not validate credentials
+```
+
+**检查**:
+1. Token 是否正确设置在 `Authorization: Bearer {token}` header
+2. Token 是否过期
+3. SECRET_KEY 是否配置正确
+
+### 问题 3: 数据库连接失败
+
+```
+psycopg.OperationalError: connection failed
+```
+
+**检查**:
+1. PostgreSQL 是否运行
+2. `.env` 中数据库配置是否正确
+3. 数据库是否存在

+
+## ⚠️ 注意事项
+
+### 1. 审计中间件
+审计中间件默认是**禁用**的。如需启用，在 `app/main.py` 中取消注释：
+
+```python
+app.add_middleware(AuditMiddleware)
+```
+
+**注意**：启用后会自动记录所有 POST/PUT/DELETE 请求，可能增加数据库负载。
+
+### 2. 向后兼容
+保留了原有的简化登录接口 `/auth/login/simple`，可以直接使用查询参数：
+
+```bash
+POST /api/v1/auth/login/simple?username=admin&password=admin123
+```
+
+### 3. 数据库连接
+确保数据库实例在应用启动时正确初始化并存储到 `app.state.db`。
+
+### 4. 权限控制示例
+为现有接口添加权限控制：
+
+```python
+from app.auth.permissions import require_role, get_current_admin
+from app.domain.models.role import UserRole
+
+# 需要管理员权限
+@router.delete("/resource/{id}")
+async def delete_resource(
+    id: int,
+    current_user = Depends(get_current_admin)
+):
+    ...
+
+# 需要操作员以上权限
+@router.post("/resource")
+async def create_resource(
+    data: dict,
+    current_user = Depends(require_role(UserRole.OPERATOR))
+):
+    ...
+```
+
+---
+
+## 🚀 完整启动流程
+
+```bash
+# 1. 进入项目目录
+cd /home/zhifu/TJWaterServer/TJWaterServerBinary
+
+# 2. 配置环境变量（如果还没有）

+## 📋 集成检查清单
+
+### 必需步骤
+
+- [ ] 复制 `.env.example` 为 `.env` 并配置
+- [ ] 生成 JWT 密钥（SECRET_KEY）
+- [ ] 生成加密密钥（ENCRYPTION_KEY）
+- [ ] 配置数据库连接信息
+- [ ] 执行用户表迁移脚本
+- [ ] 执行审计日志表迁移脚本
+- [ ] 验证默认管理员可登录
+
+### 可选步骤
+
+- [ ] 在 main.py 中添加审计中间件
+- [ ] 为现有接口添加权限控制
+- [ ] 注册新的路由（auth, user_management, audit）
+- [ ] 替换硬编码的认证逻辑
+- [ ] 配置 Token 过期时间
+
+---

+
+### 1. 配置环境变量
+
+复制 `.env.example` 为 `.env` 并配置：
+
+```bash
+cp .env.example .env
+```
+
+生成必要的密钥：
+
+```bash
+# 生成 JWT 密钥
+openssl rand -hex 32
+
+# 生成加密密钥
+python -c "from cryptography.fernet import Fernet; print(Fernet.generate_key().decode())"
+```
+
+编辑 `.env` 文件：
+
+```env
+SECRET_KEY=your-generated-jwt-secret-key
+ENCRYPTION_KEY=your-generated-encryption-key
+DB_NAME=tjwater
+DB_HOST=localhost
+DB_PORT=5432
+DB_USER=postgres
+DB_PASSWORD=your-db-password
+```
+
+### 2. 执行数据库迁移
+
+```bash
+# 连接到 PostgreSQL
+psql -U postgres -d tjwater
+
+# 执行迁移脚本
+\i migrations/001_create_users_table.sql
+\i migrations/002_create_audit_logs_table.sql
+```
+
+或使用命令行：
+
+```bash
+psql -U postgres -d tjwater -f migrations/001_create_users_table.sql
+psql -U postgres -d tjwater -f migrations/002_create_audit_logs_table.sql
+```
+
+### 3. 验证安装
+
+默认创建了两个管理员账号：
+
+- **用户名**: `admin` / **密码**: `admin123`
+- **用户名**: `tjwater` / **密码**: `tjwater@123`
+
+---
+
+## 🔐 数据加密
+
+### 使用加密器
+
+```python
+from app.core.encryption import get_encryptor
+
+encryptor = get_encryptor()
+
+# 加密敏感数据
+encrypted_data = encryptor.encrypt("sensitive information")
+
+# 解密
+decrypted_data = encryptor.decrypt(encrypted_data)
+```
+
+### 生成新密钥
+
+```python
+from app.core.encryption import Encryptor
+
+new_key = Encryptor.generate_key()
+print(f"New encryption key: {new_key}")
+```
+
+---
+
+## 👤 身份认证
+
+### 用户角色
+
+系统定义了 4 个角色（权限由低到高）：
+
+| 角色 | 权限说明 |
+|------|---------|
+| `VIEWER` | 仅查询权限 |
+| `USER` | 读写权限 |
+| `OPERATOR` | 操作员，可修改数据 |
+| `ADMIN` | 管理员，完全权限 |
+

+
+## 🔑 权限管理
+
+### 在 API 中使用权限控制
+
+#### 方式 1: 使用预定义依赖
+
+```python
+from fastapi import APIRouter, Depends
+from app.auth.permissions import get_current_admin, get_current_operator
+from app.domain.schemas.user import UserInDB
+
+router = APIRouter()
+
+@router.post("/admin-only")
+async def admin_endpoint(
+    current_user: UserInDB = Depends(get_current_admin)
+):
+    """仅管理员可访问"""
+    return {"message": "Admin access granted"}
+
+@router.post("/operator-only")
+async def operator_endpoint(
+    current_user: UserInDB = Depends(get_current_operator)
+):
+    """操作员及以上可访问"""
+    return {"message": "Operator access granted"}
+```
+
+#### 方式 2: 使用 require_role
+
+```python
+from app.auth.permissions import require_role
+from app.domain.models.role import UserRole
+
+@router.get("/viewer-access")
+async def viewer_endpoint(
+    current_user: UserInDB = Depends(require_role(UserRole.VIEWER))
+):
+    """所有认证用户可访问"""
+    return {"data": "visible to all"}
+```
+
+#### 方式 3: 手动检查权限
+
+```python
+from app.auth.dependencies import get_current_active_user
+from app.auth.permissions import check_resource_owner
+
+@router.put("/users/{user_id}")
+async def update_user(
+    user_id: int,
+    current_user: UserInDB = Depends(get_current_active_user)
+):
+    """检查是否是资源拥有者或管理员"""
+    if not check_resource_owner(user_id, current_user):
+        raise HTTPException(status_code=403, detail="Permission denied")
+    
+    # 执行更新操作
+    ...
+```
+
+---
+
+## 📝 审计日志
+
+### 自动审计
+
+使用中间件自动记录关键操作，在 `main.py` 中添加：
+
+```python
+from app.infra.audit.middleware import AuditMiddleware
+
+app.add_middleware(AuditMiddleware)
+```
+
+自动记录：
+- 所有 POST/PUT/DELETE 请求
+- 登录/登出事件
+- 关键资源访问
+
+### 手动记录审计日志
+
+```python
+from app.core.audit import log_audit_event, AuditAction
+
+await log_audit_event(
+    action=AuditAction.UPDATE,
+    user_id=current_user.id,
+    username=current_user.username,
+    resource_type="project",
+    resource_id="123",
+    ip_address=request.client.host,
+    request_data={"field": "value"},
+    response_status=200
+)
+```
+
+### 查询审计日志
+
+#### 获取所有审计日志（仅管理员）
+
+```http
+GET /api/v1/audit/logs?skip=0&limit=100
+Authorization: Bearer {admin_token}
+```
+
+#### 按条件过滤
+
+```http
+GET /api/v1/audit/logs?user_id=1&action=LOGIN&start_time=2024-01-01T00:00:00
+Authorization: Bearer {admin_token}
+```
+
+#### 获取我的操作记录
+
+```http
+GET /api/v1/audit/logs/my
+Authorization: Bearer {access_token}
+```
+
+#### 获取日志总数
+
+```http
+GET /api/v1/audit/logs/count?action=LOGIN
+Authorization: Bearer {admin_token}

+
+### Python 客户端示例
+
+```python
+import requests
+
+BASE_URL = "http://localhost:8000/api/v1"
+
+# 1. 登录
+response = requests.post(
+    f"{BASE_URL}/auth/login",
+    data={"username": "admin", "password": "admin123"}
+)
+token = response.json()["access_token"]
+
+# 2. 设置 Authorization Header
+headers = {"Authorization": f"Bearer {token}"}
+
+# 3. 获取当前用户信息
+response = requests.get(f"{BASE_URL}/auth/me", headers=headers)
+print(response.json())
+
+# 4. 创建新用户（需要管理员权限）
+response = requests.post(
+    f"{BASE_URL}/auth/register",
+    headers=headers,
+    json={
+        "username": "newuser",
+        "email": "new@example.com",
+        "password": "password123",
+        "role": "USER"
+    }
+)
+print(response.json())
+
+# 5. 查询审计日志（需要管理员权限）
+response = requests.get(
+    f"{BASE_URL}/audit/logs?action=LOGIN",
+    headers=headers
+)
+print(response.json())
+```
+
+### cURL 示例
+
+```bash
+# 登录
+curl -X POST "http://localhost:8000/api/v1/auth/login" \
+  -H "Content-Type: application/x-www-form-urlencoded" \
+  -d "username=admin&password=admin123"
+
+# 使用 Token 访问受保护接口
+TOKEN="your-access-token"
+curl -X GET "http://localhost:8000/api/v1/auth/me" \
+  -H "Authorization: Bearer $TOKEN"
+
+# 注册新用户
+curl -X POST "http://localhost:8000/api/v1/auth/register" \
+  -H "Content-Type: application/json" \
+  -H "Authorization: Bearer $TOKEN" \
+  -d '{
+    "username": "testuser",

+
+## 🛡️ 安全最佳实践
+
+1. **密钥管理**
+   - 绝不在代码中硬编码密钥
+   - 定期轮换 JWT 密钥
+   - 使用强随机密钥
+
+2. **密码策略**
+   - 最小长度 6 个字符（建议 12+）
+   - 强制密码复杂度（可在注册时添加验证）
+   - 定期提醒用户更换密码
+
+3. **Token 管理**
+   - Access Token 短期有效（默认 30 分钟）
+   - Refresh Token 长期有效（默认 7 天）
+   - 实施 Token 黑名单（可选）
+
+4. **审计日志**
+   - 审计日志不可删除
+   - 定期归档旧日志
+   - 监控异常登录行为
+
+5. **权限控制**
+   - 遵循最小权限原则
+   - 定期审查用户权限
+   - 记录所有权限变更

+## ❓ 常见问题
+
+### Q: 忘记密码怎么办？
+
+A: 目前需要管理员通过数据库重置。未来可添加邮件重置功能。
+
+```sql
+-- 重置密码为 "newpassword123"
+UPDATE users 
+SET hashed_password = '$2b$12$...' -- 使用 bcrypt 生成哈希
+WHERE username = 'targetuser';
+```
+
+### Q: 如何添加新角色？
+
+A: 编辑 `app/domain/models/role.py` 中的 `UserRole` 枚举，并更新数据库约束。
+
+### Q: 审计日志占用太多空间？
+
+A: 建议定期归档旧日志到冷存储：
+
+```sql
+-- 归档 90 天前的日志
+CREATE TABLE audit_logs_archive AS
+SELECT * FROM audit_logs WHERE timestamp < NOW() - INTERVAL '90 days';
+
+DELETE FROM audit_logs WHERE timestamp < NOW() - INTERVAL '90 days';
+```
