+**默认账号：** `admin` / `admin123`（首次登录后建议修改密码）
+
+### Docker 部署 (生产环境)
+
+**环境要求：** Docker + Docker Compose
+
+```bash
+# 1. 克隆代码
+git clone https://gitea.94kan.cn/houhuan/orc-order-v2.git
+cd orc-order-v2
+
+# 2. 配置环境变量（百度 OCR API 密钥、Gitea Token 等）
+cp .env.example .env   # 若无 .env.example，手动创建 .env
+# 编辑 .env 填入:
+#   BAIDU_OCR_API_KEY=xxx
+#   BAIDU_OCR_SECRET_KEY=xxx
+#   GITEA_TOKEN=xxx
+
+# 3. 构建并启动
+docker-compose up -d --build
+
+# 4. 访问
+#    前端: http://服务器IP:18888
+#    后端 API: http://服务器IP:18889
+#    默认账号: admin / admin123（首次登录后建议修改密码）
+
+# 常用命令
+docker-compose logs -f          # 查看日志
+docker-compose restart          # 重启服务
+docker-compose down             # 停止服务
+docker-compose up -d --build    # 重新构建并启动
+```
+
+**端口说明：**
+- `18888` — 前端 (Nginx)，对外访问入口
+- `18889` — 后端 API (FastAPI)，前端自动代理，无需直接访问
+
+**数据持久化：** `data/` 目录挂载到宿主机，SQLite 数据库、上传文件、处理结果不会因容器重建而丢失。

-**Architecture:** 单一 SQLite 数据库 (`data/web_data.db`) 存储三类数据，FastAPI 中间件自动采集 HTTP 日志，TaskManager 改造为写入 DB，前端新增两个独立页面。
-
-**Tech Stack:** FastAPI middleware, SQLite (via existing DBPool), Vue 3 + Element Plus, Pinia
-
----
-
-## 1. 数据库设计
-
-数据库文件: `data/web_data.db`，通过现有 `DBPool` 管理。
-
-### 1.1 `http_logs` 表
-
-```sql
-CREATE TABLE IF NOT EXISTS http_logs (
-    id INTEGER PRIMARY KEY AUTOINCREMENT,
-    timestamp TEXT NOT NULL,       -- ISO 8601
-    method TEXT NOT NULL,          -- GET/POST/PUT/DELETE
-    path TEXT NOT NULL,            -- /api/memory
-    status_code INTEGER,           -- 200, 404, 500
-    duration_ms REAL,              -- 请求耗时(ms)
-    user TEXT,                     -- 当前用户名
-    ip TEXT,                       -- 客户端 IP
-    detail TEXT                    -- 错误详情/备注
-);
-CREATE INDEX IF NOT EXISTS idx_http_logs_timestamp ON http_logs(timestamp);
-CREATE INDEX IF NOT EXISTS idx_http_logs_status ON http_logs(status_code);
-```
-
-### 1.2 `task_history` 表
-
-```sql
-CREATE TABLE IF NOT EXISTS task_history (
-    id TEXT PRIMARY KEY,           -- 8-char UUID
-    name TEXT NOT NULL,            -- pipeline/ocr-batch/excel/merge/sync-push/sync-pull
-    status TEXT NOT NULL,          -- pending/running/completed/failed
-    progress INTEGER DEFAULT 0,
-    message TEXT,
-    result_files TEXT,             -- JSON array of filenames
-    error TEXT,
-    log_lines TEXT,                -- JSON array of log strings
-    created_at TEXT NOT NULL,      -- ISO 8601
-    updated_at TEXT NOT NULL,      -- ISO 8601
-    completed_at TEXT              -- ISO 8601, null if not done
-);
-CREATE INDEX IF NOT EXISTS idx_task_history_status ON task_history(status);
-CREATE INDEX IF NOT EXISTS idx_task_history_created ON task_history(created_at);
-```
-
-### 1.3 `file_metadata` 表
-
-```sql
-CREATE TABLE IF NOT EXISTS file_metadata (
-    id INTEGER PRIMARY KEY AUTOINCREMENT,
-    filename TEXT NOT NULL,
-    directory TEXT NOT NULL,       -- input/output/result
-    size INTEGER,
-    action TEXT NOT NULL,          -- upload/delete/clear
-    user TEXT,
-    timestamp TEXT NOT NULL,       -- ISO 8601
-    task_id TEXT                   -- 关联的任务 ID (可选)
-);
-CREATE INDEX IF NOT EXISTS idx_file_metadata_timestamp ON file_metadata(timestamp);
-```
-
-### 1.4 自动清理
-
-30 天过期清理，在服务器启动时执行，之后每天通过 `asyncio` 定时任务执行一次：
-
-```python
-async def cleanup_old_records():
-    cutoff = (datetime.now() - timedelta(days=30)).isoformat()
-    await db_pool.execute_write("DELETE FROM http_logs WHERE timestamp < ?", cutoff)
-    await db_pool.execute_write("DELETE FROM task_history WHERE created_at < ?", cutoff)
-    await db_pool.execute_write("DELETE FROM file_metadata WHERE timestamp < ?", cutoff)
-```
-

-
-## 2. 后端架构
-
-### 2.1 新增文件
-
-| 文件 | 职责 |
-|------|------|
-| `web/backend/services/db_schema.py` | 建表 SQL + `init_db()` + `cleanup_old_records()` |
-| `web/backend/middleware/logging.py` | HTTP 请求日志中间件 |
-| `web/backend/routers/logs.py` | 日志查询 API |
-| `web/backend/routers/tasks.py` | 任务历史 API |
-
-### 2.2 修改文件
-
-| 文件 | 改动 |
-|------|------|
-| `web/backend/main.py` | lifespan 中调用 `init_db()`，挂载 logging 中间件，注册 logs/tasks 路由 |
-| `web/backend/services/task_manager.py` | `update_progress()` 和 `_finish()` 写入 task_history 表 |
-| `web/backend/routers/files.py` | upload/delete/clear 操作写入 file_metadata 表 |
-
-### 2.3 API 端点
-
-**日志 (`/api/logs`)**
-- `GET /api/logs` — 分页查询
-  - 参数: `page`, `page_size`, `method`, `status_code`, `path`(搜索), `start_date`, `end_date`
-  - 返回: `{ items: [...], total: number }`
-- `GET /api/logs/stats` — 统计概览
-  - 返回: `{ today_count, error_count, avg_duration_ms, error_rate }`
-
-**任务历史 (`/api/tasks`)**
-- `GET /api/tasks` — 分页查询
-  - 参数: `page`, `page_size`, `status`, `name`(类型筛选), `search`
-  - 返回: `{ items: [...], total: number }`
-- `GET /api/tasks/{task_id}` — 任务详情（含完整 log_lines）
-- `POST /api/tasks/{task_id}/retry` — 重试失败任务
-  - 根据 `name` 字段重新调用对应处理端点
-
-**文件历史 (`/api/files`)**
-- `GET /api/files/history` — 文件操作记录
-  - 参数: `page`, `page_size`, `directory`, `action`
-  - 返回: `{ items: [...], total: number }`
-- `GET /api/files/stats` — 存储统计
-  - 返回: `{ directories: [{ name, file_count, total_size }] }`
-
-### 2.4 中间件设计
-
-```python
-async def logging_middleware(request: Request, call_next):
-    # 跳过静态资源和 WebSocket
-    if request.url.path.startswith("/assets") or request.url.path.startswith("/ws"):
-        return await call_next(request)
-
-    start = time.time()
-    response = await call_next(request)
-    duration_ms = (time.time() - start) * 1000
-
-    # 异步写入日志（不阻塞响应）
-    asyncio.create_task(write_log(
-        method=request.method,
-        path=request.url.path,
-        status_code=response.status_code,
-        duration_ms=duration_ms,
-        user=get_current_user_from_request(request),
-        ip=request.client.host,
-    ))
-    return response
-```
-
-### 2.5 TaskManager 改造
-
-现有 `TaskManager.update_progress()` 和 `_finish()` 方法中增加 DB 写入：
-
-```python
-async def update_progress(self, task_id: str, progress: int, message: str):
-    task = self._tasks[task_id]
-    task.progress = progress
-    task.message = message
-    task.log_lines.append(message)
-    # 新增：写入 DB
-    await self._db.execute_write(
-        "UPDATE task_history SET progress=?, message=?, log_lines=?, updated_at=? WHERE id=?",
-        progress, message, json.dumps(task.log_lines), datetime.now().isoformat(), task_id
-    )
-    await self._broadcast(task)
-```
-
----
-
-## 3. 前端设计
-
-### 3.1 新增页面
-
-**侧边栏导航新增 2 项：**
-
-| 页面 | 路由 | 图标 | 标签 |
-|------|------|------|------|
-| 任务历史 | `/tasks` | `Timer` | - |
-| 日志中心 | `/logs` | `Notebook` | - |
-
-### 3.2 任务历史页面 (`Tasks.vue`)
-
-**布局：**
-- 顶部统计卡片行（4 卡片）：总任务数 / 成功 / 失败 / 运行中
-- 筛选栏：状态下拉（全部/成功/失败/运行中）+ 类型下拉（全部/pipeline/ocr/excel/merge）+ 搜索框
-- 表格列：任务ID、类型、状态（彩色标签）、进度条、耗时、创建时间、操作
-- 操作：查看详情（弹窗显示完整日志流）、重试（仅失败任务）
-
-**详情弹窗：**
-- 任务基本信息（类型/状态/耗时/结果文件）
-- 终端风格日志流（复用 Dashboard 的 log-box 样式）
-- 结果文件列表（可下载）
-
-### 3.3 日志中心页面 (`Logs.vue`)
-
-**布局：**
-- 顶部统计卡片行（4 卡片）：今日请求 / 错误数 / 平均耗时 / 错误率
-- 筛选栏：时间范围选择器（今天/7天/30天）+ 方法筛选（GET/POST/PUT/DELETE）+ 状态码筛选（2xx/4xx/5xx）+ 路径搜索
-- 表格列：时间、方法（彩色标签）、路径、状态码（颜色区分）、耗时、用户
-- 点击行展开详情面板（IP 地址、错误信息）
-
-### 3.4 Dashboard 增强
-
-- stats-row 第三列从硬编码 "记忆库 5591" 改为动态存储统计（磁盘用量）
-- 文件列表区新增「操作历史」按钮，弹窗显示该目录的 file_metadata 记录
-
-### 3.5 新增文件
-
-| 文件 | 职责 |
-|------|------|
-| `web/frontend/src/views/Tasks.vue` | 任务历史页面 |
-| `web/frontend/src/views/Logs.vue` | 日志中心页面 |
-| `web/frontend/src/stores/tasks.ts` | 任务历史状态管理（可选，可用 api 直接调用） |
-
-### 3.6 修改文件
-
-| 文件 | 改动 |
-|------|------|
-| `web/frontend/src/views/Layout.vue` | navItems 新增 2 项 |
-| `web/frontend/src/router/index.ts` | 新增 2 个路由 |
-| `web/frontend/src/views/Dashboard.vue` | stats-row 动态化 + 文件历史弹窗 |
-
----
-
-## 4. 安全与性能
-
-- 日志查询 API 仅限认证用户
-- HTTP 日志不记录请求体（避免泄露敏感数据）
-- 中间件使用 `asyncio.create_task()` 异步写入，不阻塞响应
-- 日志表索引：`timestamp`、`status_code`、`path`
-- 任务表索引：`status`、`created_at`
-- 自动清理 30 天前的记录，防止数据库无限增长
-- 分页查询默认 page_size=50，最大 200
-
----
-
-## 5. 实施顺序
-
-1. **Phase 1: 数据库 + 后端**
-   - db_schema.py（建表 + 清理）
-   - logging 中间件
-   - task_manager 改造
-   - files.py 改造
-   - logs.py + tasks.py 路由
-
-2. **Phase 2: 前端页面**
-   - Tasks.vue
-   - Logs.vue
-   - Layout.vue 路由注册
-   - Dashboard.vue 增强
-
-3. **Phase 3: 集成测试**
-   - npm run build
-   - 端到端验证：操作 → 日志记录 → 任务历史 → 文件历史
