+# 文件翻譯 Web 系統開發進度
+
+## 專案概述
+將現有的桌面版文件翻譯工具 (document_translator_gui_with_backend.py) 轉換為 Web 化系統，提供 AD 帳號登入、工作隔離、任務排隊、郵件通知等企業級功能。
+
+## 已完成項目 ✅
+
+### 1. 需求分析與設計階段
+- ✅ **PRD.md 產品需求文件** 
+  - 位置：`C:\Users\EGG\WORK\data\user_scrip\TOOL\Document_translator_V2\PRD.md`
+  - 完整定義功能需求、非功能需求、技術規格
+  - 確認使用 Dify API（從 api.txt 讀取配置）
+  - 檔案大小限制 25MB，單檔依序處理
+  - 管理員權限：ymirliu@panjit.com.tw
+  - 資料庫表前綴：dt_
+
+- ✅ **TDD.md 技術設計文件** (由 system-architect agent 完成)
+  - 位置：`C:\Users\EGG\WORK\data\user_scrip\TOOL\Document_translator_V2\TDD.md`
+  - 完整的系統架構設計（Flask + Vue 3）
+  - 資料庫 schema 設計（MySQL，6個核心資料表）
+  - RESTful API 規格定義
+  - 前後端互動流程設計
+
+### 2. 後端開發階段
+- ✅ **完整後端 API 系統** (由 backend-implementation-from-tdd agent 完成)
+  - 位置：`C:\Users\EGG\WORK\data\user_scrip\TOOL\Document_translator_V2\app.py`
+  - Flask 3.0 應用程式架構
+  - LDAP3 整合 panjit.com.tw AD 認證
+  - MySQL 資料庫模型（使用 dt_ 前綴）
+  - Celery + Redis 任務佇列處理
+  - Dify API 整合與成本追蹤（從 metadata 取得實際費用）
+  - SMTP 郵件通知服務
+  - 管理員統計報表功能
+  - 完整錯誤處理與重試機制
+  - 檔案自動清理機制（7天）
+  - 完整測試程式碼
+  - 啟動腳本：`start_dev.bat`
+
+### 3. 前端開發階段
+- ✅ **完整前端 Web 介面** (由 frontend-developer agent 完成)
+  - 位置：`C:\Users\EGG\WORK\data\user_scrip\TOOL\Document_translator_V2\frontend\`
+  - Vue 3 + Vite + Element Plus 架構
+  - AD 帳號登入介面
+  - 拖拽檔案上傳功能
+  - 任務列表與即時狀態更新
+  - 管理員報表與系統監控
+  - WebSocket 即時通訊
+  - 響應式設計
+  - 生產環境打包配置
+  - 啟動腳本：`start_frontend.bat`
+
+## 待完成項目 📋
+
+### 4. QA 測試階段
+- ⏳ **整合測試** (下一步執行)
+  - 前後端整合測試
+  - LDAP 認證流程測試
+  - 檔案上傳下載測試
+  - 翻譯功能完整流程測試
+  - 郵件通知測試
+  - 管理員功能測試
+  - 錯誤處理與重試機制測試
+  - 效能與壓力測試
+
+- ⏳ **最終測試報告產出**
+  - 功能測試結果
+  - 效能測試數據
+  - 安全性檢查報告
+  - 部署準備檢查清單
+
+## 系統技術架構
+
+### 前端技術棧
+- **框架**: Vue 3 + Composition API
+- **構建工具**: Vite 4.x
+- **UI 元件庫**: Element Plus 2.3+
+- **狀態管理**: Pinia 2.x
+- **路由**: Vue Router 4.x
+- **樣式**: SCSS + 響應式設計
+
+### 後端技術棧
+- **Web 框架**: Flask 3.0+
+- **資料庫**: MySQL 8.0 (現有環境)
+- **ORM**: SQLAlchemy
+- **任務佇列**: Celery + Redis
+- **認證**: LDAP3
+- **翻譯 API**: Dify API
+- **郵件**: SMTP (mail.panjit.com.tw)
+
+### 資料庫設計
+使用 `dt_` 前綴的6個核心資料表：
+1. `dt_users` - 使用者資訊
+2. `dt_translation_jobs` - 翻譯任務
+3. `dt_job_files` - 檔案記錄
+4. `dt_translation_cache` - 翻譯快取
+5. `dt_api_usage_stats` - API使用統計
+6. `dt_system_logs` - 系統日誌
+
+## 重要配置檔案
+
+### 環境配置
+- **後端環境變數**: `.env` (包含資料庫、LDAP、SMTP配置)
+- **Dify API配置**: `api.txt` (base_url 和 api key)
+- **前端環境變數**: `frontend/.env`
+
+### 關鍵特性
+1. **工作隔離**: 每位使用者只能查看自己的任務
+2. **管理員功能**: ymirliu@panjit.com.tw 專屬管理後台
+3. **成本追蹤**: 自動從 Dify API response metadata 記錄實際費用
+4. **智慧重試**: 3次重試機制，逐步延長間隔
+5. **自動清理**: 7天後自動刪除檔案
+6. **即時通知**: SMTP郵件 + WebSocket即時更新
+
+## 明天待辦事項
+
+1. **啟動 QA Agent 進行整合測試**
+   - 執行完整的前後端整合測試
+   - 驗證所有功能模組是否正常運作
+   - 測試錯誤處理與重試機制
+   - 確認管理員功能運作正常
+
+2. **完成最終測試報告**
+   - 整理所有測試結果
+   - 確認系統準備就緒狀態
+   - 提供部署與使用指南
+
+## 專案狀態
