-# Playwright 浏览器部署指南
-
-## 概述
-
-本文档为开发人员提供 ERPAuto 应用程序中 Playwright Chromium 浏览器的部署指南。文档说明如何将浏览器文件从开发机复制到目标用户机器，确保应用程序能够正常运行浏览器自动化任务。
-
-**重要提示**：部署前请先阅读 [BROWSER_VERSIONS.md](./BROWSER_VERSIONS.md) 了解版本信息。
-
-## 目标路径
-
-浏览器文件必须部署在以下路径：
-
-```
-%APPDATA%\erpauto\ms-playwright\chromium-1208\
-```
-
-完整展开路径示例（Windows）：
-
-```
-C:\Users\<用户名>\AppData\Roaming\erpauto\ms-playwright\chromium-1208\
-```
-
-## 目录结构
-
-部署完成后，目标目录结构应如下所示：
-
-```
-%APPDATA%\erpauto\ms-playwright\
-└── chromium-1208/
-    └── chrome-win/
-        ├── chrome.exe              # 浏览器可执行文件
-        ├── chrome_dll.dll
-        ├── resources/
-        ├── locales/
-        └── ...                     # 其他浏览器文件
-```
-
-**关键文件**：`chrome-win/chrome.exe` 必须存在，否则浏览器无法启动。
-
-## 部署步骤
-
-### 步骤 1：在开发机上准备
-
-1. 确保开发机已安装正确版本的 Playwright：
-
-   ```bash
-   npm install playwright@1.58.2
-   ```
-
-2. 下载 Chromium 浏览器：
-
-   ```bash
-   npx playwright install chromium
-   ```
-
-3. 定位开发机上的浏览器缓存目录：
-
-   ```
-   C:\Users\<开发机用户名>\AppData\Local\ms-playwright\chromium-1208
-   ```
-
-### 步骤 2：复制文件
-
-1. **复制整个浏览器目录**
-   - 将开发机上的 `chromium-1208` 目录完整复制
-   - 不要只复制部分文件，确保所有子目录和文件都包含在内
-
-2. **粘贴到目标路径**
-   - 在目标机器上创建目录：`%APPDATA%\erpauto\ms-playwright\`
-   - 将 `chromium-1208` 目录粘贴到该路径下
-
-3. **验证文件完整性**
-   - 确认目标路径存在：`%APPDATA%\erpauto\ms-playwright\chromium-1208\chrome-win\chrome.exe`
-   - 检查文件大小约为 280MB
-
-### 步骤 3：配置环境变量（可选）
-
-如需确保应用程序使用正确的浏览器路径，可设置以下环境变量：
-
-```batch
-set PLAYWRIGHT_BROWSERS_PATH=%APPDATA%\erpauto\ms-playwright
-```
-
-或在应用程序代码中设置：
-
-```javascript
-process.env.PLAYWRIGHT_BROWSERS_PATH = path.join(app.getPath('userData'), 'ms-playwright')
-```
-
-## 验证步骤
-
-部署完成后，执行以下验证步骤：
-
-### 验证 1：检查目录结构
-
-在目标机器上运行：
-
-```batch
-dir %APPDATA%\erpauto\ms-playwright\chromium-1208\chrome-win\chrome.exe
-```
-
-应显示文件存在。
-
-### 验证 2：启动浏览器测试
-
-运行 ERPAuto 应用程序，执行以下操作：
-
-1. 登录应用程序
-2. 进入「数据提取」页面
-3. 输入一个有效订单号
-4. 点击「开始提取」
-5. 观察浏览器是否正常启动并执行任务
-
-### 验证 3：检查日志
-
-查看应用程序日志，确认没有浏览器相关的错误信息：
-
- 无 "browser not found" 错误
- 无 "chromium revision not found" 错误
- 无 "PLAYWRIGHT_BROWSERS_PATH" 相关警告
-
-## 故障排查
-
-### 问题 1：浏览器无法启动
-
-**症状**：应用程序报错，提示找不到浏览器或启动失败。
-
-**解决方案**：
-
-1. 确认修订号匹配（必须是 1208）
-2. 检查 `chrome-win/chrome.exe` 文件是否存在
-3. 验证 `PLAYWRIGHT_BROWSERS_PATH` 环境变量设置正确
-4. 确认目标机器具有相同的 Playwright 版本（1.58.2）
-
-### 问题 2：版本不匹配错误
-
-**症状**：应用程序启动时报出版本冲突错误。
-
-**解决方案**：
-
-1. 检查 `package.json` 中的 Playwright 版本是否为 1.58.2
-2. 确认复制的 Chromium 修订号为 1208
-3. 参考 [BROWSER_VERSIONS.md](./BROWSER_VERSIONS.md) 核对所有版本信息
-
-### 问题 3：权限不足
-
-**症状**：无法写入或读取浏览器目录。
-
-**解决方案**：
-
-1. 确保目标目录具有适当的读写权限
-2. 以管理员身份运行应用程序进行测试
-3. 检查防病毒软件是否阻止了浏览器执行
-
-### 问题 4：路径错误
-
-**症状**：应用程序在错误的位置查找浏览器文件。
-
-**解决方案**：
-
-1. 确认 `%APPDATA%` 环境变量指向正确的用户目录
-2. 检查应用程序是否正确解析了 `userData` 路径
-3. 在代码中硬编码浏览器路径进行调试
-
-## 注意事项
-
- **仅部署 Chromium**：ERPAuto 只需要 Chromium 浏览器，不需要 Firefox 或 WebKit
- **版本一致性**：开发机和目标机器的 Playwright 版本必须一致
- **修订号匹配**：Chromium 修订号（1208）必须完全匹配，否则可能出现兼容性问题
- **文件完整性**：复制时确保所有文件完整，损坏的浏览器文件会导致启动失败
- **网络隔离环境**：目标机器如果无法访问互联网，必须提前部署浏览器文件，因为无法自动下载

-## Architecture Overview
+发布：

-ERPAuto is an **Electron desktop application** for automating ERP system data processing. The application follows the classic Electron architecture with three distinct processes:
+```bash
+npm run release:publish -- --channel stable
+npm run release:publish -- --channel preview
+```

-### Process Structure
+详细发布流程见：
+[docs/build-and-release-guide.md](/d:/FileLib/Projects/CodeMigration/ERPAuto/docs/build-and-release-guide.md)

-1. **Main Process** (`src/main/`)
-   - Node.js environment managing application lifecycle
-   - Entry point: `src/main/index.ts`
-   - Registers all IPC handlers via `registerIpcHandlers()`
-   - Loads configuration from `config.yaml` via ConfigManager at startup
+## 代码结构

-2. **Preload Script** (`src/preload/`)
-   - Security bridge between main and renderer processes
-   - Exposes type-safe APIs via `contextBridge` as `window.electron` and `window.api`
-   - Central API surface organized by domain (auth, extractor, cleaner, database, etc.)
+### 主进程

-3. **Renderer Process** (`src/renderer/`)
-   - React 19 + TypeScript UI
-   - Uses exposed preload APIs for all main process communication
-   - Authentication-based routing with role-based access control
+- 路径：`src/main/`
+- 入口：`src/main/index.ts`
+- 职责：
+  - 应用生命周期管理
+  - 配置加载
+  - IPC 注册
+  - 更新服务初始化

-### Service Architecture
+### 预加载层

-The main process is organized around domain-specific services in `src/main/services/`:
+- 路径：`src/preload/`
+- 职责：
+  - 暴露 `window.electron` API
+  - 作为 renderer 和 main 之间的安全桥

- **ERP Services** (`services/erp/`): Browser automation using Playwright
-  - `ExtractorService` - Downloads material plan data
-  - `CleanerService` - Deletes specified materials with dry-run support
-  - `ErpAuthService` - Handles ERP authentication
-  - `OrderResolverService` - Validates and resolves order numbers
-  - `locators.ts` - ERP element selectors
+### 渲染进程

- **Database Services** (`services/database/`): Dual database support
-  - `MySqlService` / `mysql.ts` - MySQL operations
-  - `SqlServerService` / `sql-server.ts` - SQL Server operations
-  - DAO pattern: `discrete-material-plan-dao.ts`, `materials-to-be-deleted-dao.ts`
+- 路径：`src/renderer/`
+- 技术：React + TypeScript
+- 特点：
+  - 通过 preload 暴露的 API 调用主进程
+  - 以登录状态和角色控制主要功能入口

- **User Services** (`services/user/`): Authentication and session management
-  - `BipUsersDao` - User data access
-  - `SessionManager` - Active session tracking
+### 服务层

- **Other Services**:
-  - `config/` - Configuration management
-  - `excel/` - Excel file parsing
+主进程服务集中在 `src/main/services/`，按领域拆分：

-### IPC Handler Pattern
+- `erp/`：ERP 浏览器自动化
+- `database/`：MySQL / SQL Server
+- `user/`：登录、会话、用户切换
+- `config/`：YAML 配置管理
+- `update/`：便携版更新
+- `excel/`：Excel 处理

-All IPC communication follows a consistent pattern:
+## 关键事实

- Handlers are in `src/main/ipc/`, organized by domain (8 modules)
- Each handler module exports a `register*Handlers()` function
- All handlers are registered in `src/main/ipc/index.ts`
- Channel naming follows `domain:action` convention (e.g., `extractor:run`, `auth:login`)
+### 配置系统

-### Authentication Flow
+- 使用 YAML 配置
+- 模板文件：`config.template.yaml`
+- 开发环境通常使用项目根目录下的 `config.yaml`
+- 生产环境会将配置放到用户目录

-The application implements a multi-stage authentication system:
+### IPC 组织方式

-1. **Silent Login**: On startup, attempts automatic login using computer name
-2. **Fallback**: Shows login dialog if silent login fails
-3. **Admin User Selection**: Admin users can switch to other user accounts
-4. **Session Management**: Persistent sessions with role-based permissions (Admin/User/Guest)
+- 所有 IPC handler 在 `src/main/ipc/`
+- 每个领域一个 handler 模块
+- 统一在 `src/main/ipc/index.ts` 注册
+- channel 命名遵循 `domain:action`

-Admin users see logout buttons and can access user switching. Non-admin users have restricted access based on the user who initiated their session.
+### 认证与角色

-### Type System
+当前主要角色是：

- Separate TypeScript configs: `tsconfig.node.json` (main/preload) and `tsconfig.web.json` (renderer)
- Types are co-located with features: `src/main/types/` contains domain-specific type definitions
- The preload script exposes a typed API surface that's available in renderer
+- `Admin`
+- `User`
+- `Guest`

-### Path Aliases
+登录流程支持：

- `@renderer` → `src/renderer/src` (renderer process)
- `@main` → `src/main` (main process, tests only)
- `@services` → `src/main/services` (main process, tests only)
- `@types` → `src/main/types` (main process, tests only)
+- 静默登录
+- 普通登录
+- 管理员切换用户

-## Configuration Management
+### 便携版自动更新

-The application uses a YAML-based configuration system (`config.yaml`) managed by `ConfigManager`:
+项目已实现 Windows 便携版更新，关键点：

- **Development**: `config.yaml` in project root (easy to edit and version control)
- **Production**: `config.yaml` in user data directory (AppData on Windows)
+- 更新检查基于登录用户角色
+- 支持 `stable` / `preview` 双通道
+- `User` 只看 `stable`
+- `Admin` 同时看 `stable` 和 `preview`
+- 使用原生 `portable-updater.exe` 完成替换，不依赖 PowerShell

-Key configurations in `config.yaml`:
+相关文档：

- **ERP Settings**: URL (fixed infrastructure)
- **Database**: MySQL and SQL Server connection configs (dual support)
- **Paths**: Data directory and output file settings
- **Extraction**: Batch size, verbosity, persistence options
- **Validation**: Data source, batch size, match mode
- **Order Resolution**: Database table and field names for order number lookup
+- [docs/portable-auto-update-architecture.md](/d:/FileLib/Projects/CodeMigration/ERPAuto/docs/portable-auto-update-architecture.md)
+- [docs/build-and-release-guide.md](/d:/FileLib/Projects/CodeMigration/ERPAuto/docs/build-and-release-guide.md)

-Note: ERP credentials (username/password) are stored in the database (`dbo_BIPUsers` table) per user, managed via the Settings UI.
+## 代理工作约束

-## Key Technologies
+1. 优先修改现有文件，不要随意新建同类文件。
+2. 变更前先理解对应模块的现有模式，尽量保持风格一致。
+3. renderer 不要直接访问 Node/Electron 能力，统一走 preload。
+4. 配置、IPC、类型定义通常需要同步更新，避免只改一层。
+5. 涉及发布、更新、构建链路时，优先复用现有脚本，不要重复实现。
+6. 涉及浏览器部署或更新流程时，先看 `docs/` 里的专题文档。

- **Electron 39** - Desktop framework
- **React 19** - UI framework
- **TypeScript 5.9** - Type safety
- **Playwright 1.58** - Browser automation for ERP interaction
- **electron-vite + Vite 7** - Build tooling
- **Zod** - Runtime validation

-# Playwright 部署说明
-
-## 浏览器路径问题修复
-
-### 问题描述
-
-应用启动时提示"浏览器文件未找到"，但浏览器文件已经放置在正确路径下。
-
-**原因**：Playwright 1.48+ 改变了浏览器目录命名规则：
-
- **旧格式**：`chromium-win32/chrome.exe`
- **新格式**：`chromium-1208/chrome-win64/chrome.exe`（revision 号可能不同）
-
-### 解决方案
-
-代码已更新为自动检测新旧两种格式，并显示当前目录内容以便调试。
-
-## 快速部署
-
-### 方法 1：使用 Playwright CLI（推荐）
-
-```bash
-# 在应用目录运行
-npx playwright install chromium
-```
-
-浏览器会自动下载并安装到正确位置：
-
- **用户数据目录**：`%APPDATA%\erpauto\ms-playwright\`
- **完整路径**：`C:\Users\pengq\AppData\Roaming\erpauto\ms-playwright\chromium-<revision>\chrome-win64\chrome.exe`
-
-### 方法 2：手动复制
-
-如果你已经有 Playwright 浏览器文件，可以复制到应用的用户数据目录：
-
-1. 找到现有浏览器文件（通常在 `%USERPROFILE%\AppData\Local\ms-playwright`）
-2. 复制到 `%APPDATA%\erpauto\ms-playwright\`
-3. 确保目录结构正确：
-   ```
-   ms-playwright/
-   ├── chromium-1208/
-   │   ├── chrome-win64/
-   │   │   └── chrome.exe
-   │   └── INSTALLATION_COMPLETE
-   └── chromium_headless_shell-1208/
-       └── ...
-   ```
-
-### 方法 3：使用 PLAYWRIGHT_BROWSERS_PATH 环境变量
-
-将浏览器文件放在共享位置，然后设置环境变量：
-
-```bash
-# 系统环境变量
-setx PLAYWRIGHT_BROWSERS_PATH "D:\shared\playwright-browsers"
-```
-
-或在应用启动脚本中设置。
-
-## 验证安装
-
-运行应用后，检查是否还有错误提示。如果没有浏览器错误，说明安装成功。
-
-你也可以在应用日志中查找：
-
- `Found Chromium revision: chromium-1208` - 表示成功找到浏览器
- `Playwright browser not found` - 表示未找到，会显示可用目录列表
-
-## 常见问题
-
-### Q: 显示"浏览器文件未找到"但文件确实在那里
-
-检查目录结构是否正确：
-
-```powershell
-# 查看当前目录内容
-Get-ChildItem $env:APPDATA\erpauto\ms-playwright
-
-# 检查 chrome.exe 是否存在
-Test-Path "$env:APPDATA\erpauto\ms-playwright\chromium-*/chrome-win64/chrome.exe"
-```
-
-### Q: 不同用户使用同一个浏览器文件
-
-使用环境变量 `PLAYWRIGHT_BROWSERS_PATH` 指向共享目录。
-
-### Q: 离线部署
-
-1. 在有网络的机器上运行 `npx playwright install chromium`
-2. 复制整个 `ms-playwright` 目录
-3. 在目标机器上设置 `PLAYWRIGHT_BROWSERS_PATH` 指向该目录
-
-## 下次构建
-
-只需运行：
-
-```bash
-npm run build:win
-```
-
-所有配置已保存，Playwright 模块和浏览器路径检查会自动处理。

+# Playwright 浏览器版本信息
+
+本文档记录 ERPAuto 当前使用的 Playwright 版本，以及代码中采用的浏览器目录约定。
+
+## 当前版本
+
+根据 [package.json](/d:/FileLib/Projects/CodeMigration/ERPAuto/package.json)，项目当前依赖为：
+
+| 组件 | 当前版本 |
+| --- | --- |
+| `playwright` | `^1.58.2` |
+| `playwright-core` | `^1.58.2` |
+| `@playwright/test` | `^1.58.2` |
+
+## 当前代码中的目录约定
+
+根据 [src/main/index.ts](/d:/FileLib/Projects/CodeMigration/ERPAuto/src/main/index.ts)，应用启动时会把：
+
+```text
+PLAYWRIGHT_BROWSERS_PATH = %APPDATA%\erpauto\ms-playwright
+```
+
+随后按以下顺序检查 Chromium：
+
+1. 优先检查：
+
+```text
+%APPDATA%\erpauto\ms-playwright\chromium-1208\chrome-win64\chrome.exe
+```
+
+2. 兼容旧结构：
+
+```text
+%APPDATA%\erpauto\ms-playwright\chromium-win32\chrome.exe
+```
+
+3. 如果仍然找不到，则继续扫描任意 `chromium-*` 目录，并尝试：
+
+```text
+%APPDATA%\erpauto\ms-playwright\chromium-<revision>\chrome-win64\chrome.exe
+```
+
+这意味着：
+
+- `chromium-1208` 是当前代码优先查找的默认 revision
+- 但应用并不只接受 `1208`
+- 当前主目录结构是 `chrome-win64`
+
+## 推荐目录结构
+
+### Windows 开发环境
+
+```text
+C:\Users\<用户名>\AppData\Local\ms-playwright\
+└── chromium-1208/
+    └── chrome-win64/
+        ├── chrome.exe
+        └── ...
+```
+
+### 目标部署环境
+
+```text
+%APPDATA%\erpauto\ms-playwright\
+└── chromium-1208/
+    └── chrome-win64/
+        ├── chrome.exe
+        └── ...
+```
+
+如果不是 `1208`，只要目录名满足 `chromium-*` 且内部存在 `chrome-win64\chrome.exe`，当前代码也能识别。
+
+## 使用建议
+
+### 开发环境准备
+
+1. 安装项目依赖：
+
+```bash
+npm install
+```
+
+2. 下载 Chromium 浏览器：
+
+```bash
+npx playwright install chromium
+```
+
+### 复制浏览器文件
+
+1. 在开发机上找到 Playwright 浏览器缓存目录：
+
+```text
+C:\Users\<用户名>\AppData\Local\ms-playwright\
+```
+
+2. 复制完整的 `chromium-*` 目录到目标路径：
+
+```text
+%APPDATA%\erpauto\ms-playwright\
+```
+
+3. 确保内部存在：
+
+```text
+chrome-win64\chrome.exe
+```
+
+## 注意事项
+
+- ERPAuto 当前只依赖 Chromium，不需要 Firefox 和 WebKit
+- 浏览器文件体积较大，建议按整个 revision 目录复制
+- 当前代码会优先尝试 `chromium-1208`
+- 但从实现角度看，“revision 严格等于 1208”不是唯一成功条件
+- 真正关键的是目录结构与可执行文件路径满足当前查找规则
+
+## 故障排查
+
+### 浏览器无法启动
+
+优先检查：
+
+1. `%APPDATA%\erpauto\ms-playwright\` 是否存在
+2. 是否存在 `chromium-1208\chrome-win64\chrome.exe`
+3. 是否存在其他 `chromium-*` 目录，且包含 `chrome-win64\chrome.exe`
+4. 是否误用了过时的 `chrome-win\chrome.exe` 路径
+
+### 版本不匹配或路径不匹配
+
+建议同时确认：
+
+- `package.json` 中的 Playwright 版本
+- 目标机器上实际部署的 Chromium 目录
+- 当前目录结构是否为 `chrome-win64\chrome.exe`
+- 应用启动时是否能在 `%APPDATA%\erpauto\ms-playwright\` 下扫描到有效 revision

+# Playwright 部署说明
+
+本文档聚焦“如何让 ERPAuto 在目标机器上拥有可用的 Playwright Chromium 浏览器”，适合作为实际部署操作说明。
+
+如果你想看版本信息，请同时参考：
+
+- [BROWSER_VERSIONS.md](./BROWSER_VERSIONS.md)
+
+## 背景
+
+ERPAuto 启动时会把 `PLAYWRIGHT_BROWSERS_PATH` 设置到：
+
+```text
+%APPDATA%\erpauto\ms-playwright
+```
+
+随后在该目录下查找 Chromium 浏览器文件。当前代码支持：
+
+- `chromium-1208\chrome-win64\chrome.exe`
+- `chromium-win32\chrome.exe`
+- 任意 `chromium-*` 目录下的 `chrome-win64\chrome.exe`
+
+因此，部署的本质就是把一个完整可用的 Chromium revision 目录放到这个位置。
+
+当前查找顺序是：
+
+1. 先查 `%APPDATA%\erpauto\ms-playwright\chromium-1208\chrome-win64\chrome.exe`
+2. 再查 `%APPDATA%\erpauto\ms-playwright\chromium-win32\chrome.exe`
+3. 最后扫描任意 `chromium-*` 目录下的 `chrome-win64\chrome.exe`
+
+所以从部署角度看，真正重要的不是目录名一定等于 `1208`，而是目录结构满足当前实现的查找规则。
+
+## 推荐部署方式
+
+### 方式 1：使用 Playwright CLI
+
+如果目标机器能联网，最简单的方式是在项目目录执行：
+
+```bash
+npx playwright install chromium
+```
+
+执行后，需要把下载得到的 `chromium-*` 目录放到：
+
+```text
+%APPDATA%\erpauto\ms-playwright\
+```
+
+说明：
+
+- Playwright 默认下载目录通常是 `%LOCALAPPDATA%\ms-playwright\`
+- ERPAuto 运行时查找的是 `%APPDATA%\erpauto\ms-playwright\`
+- 所以“下载成功”不等于“应用一定能找到”，最终还是要确保文件落在 ERPAuto 使用的目录下
+
+### 方式 2：手动复制
+
+这是离线环境或最稳定的部署方式。
+
+1. 在一台已完成 `npx playwright install chromium` 的机器上找到：
+
+```text
+C:\Users\<用户名>\AppData\Local\ms-playwright\
+```
+
+2. 复制完整的 `chromium-*` 目录，例如：
+
+```text
+chromium-1208
+```
+
+3. 将该目录复制到目标机器：
+
+```text
+%APPDATA%\erpauto\ms-playwright\
+```
+
+4. 确认内部存在：
+
+```text
+chrome-win64\chrome.exe
+```
+
+## 推荐目录示例
+
+```text
+%APPDATA%\erpauto\ms-playwright\
+└── chromium-1208/
+    └── chrome-win64/
+        ├── chrome.exe
+        ├── chrome.dll
+        ├── locales/
+        ├── resources/
+        └── ...
+```
+
+如果你使用的是旧结构，也可兼容：
+
+```text
+%APPDATA%\erpauto\ms-playwright\
+└── chromium-win32/
+    └── chrome.exe
+```
+
+## 验证方式
+
+### 验证 1：检查文件
+
+执行：
+
+```powershell
+Get-ChildItem $env:APPDATA\erpauto\ms-playwright
+```
+
+如果使用默认 revision，再执行：
+
+```powershell
+Test-Path "$env:APPDATA\erpauto\ms-playwright\chromium-1208\chrome-win64\chrome.exe"
+```
+
+如果你部署的是其他 revision，请按实际目录替换。
+
+### 验证 2：启动应用
+
+启动 ERPAuto，观察是否仍弹出“浏览器文件未找到”错误框。
+
+如果没有弹窗，通常说明启动时的浏览器路径检查已经通过。
+
+### 验证 3：执行真实业务
+
+进入依赖 Playwright 的功能页面，执行一次真实流程，确认浏览器可以正常启动。
+
+## 常见问题
+
+### 问题 1：文件明明存在，但应用还是报找不到
+
+常见原因：
+
+1. 文件放在 `%LOCALAPPDATA%\ms-playwright\`，而不是 `%APPDATA%\erpauto\ms-playwright\`
+2. 目录结构是旧文档里的 `chrome-win\chrome.exe`
+3. revision 目录名不符合 `chromium-*`
+4. 缺少 `chrome-win64\chrome.exe`
+
+### 问题 2：想多个用户共用同一份浏览器文件
+
+当前代码在应用启动时会直接把 `PLAYWRIGHT_BROWSERS_PATH` 设为：
+
+```text
+%APPDATA%\erpauto\ms-playwright
+```
+
+所以默认行为是“每个用户使用自己的用户目录”。  
+如果要改成共享目录，需要同时改代码，而不是只改系统环境变量。
+
+### 问题 3：构建时是否会自动打包 Chromium
+
+不会。
+
+当前 [package.json](/d:/FileLib/Projects/CodeMigration/ERPAuto/package.json) 的 `build:win` 明确设置了：
+
+```text
+PLAYWRIGHT_SKIP_BROWSER_DOWNLOAD=1
+```
+
+也就是说：
+
+- 构建过程不会自动下载浏览器
+- 打包产物也不自带 Chromium
+- 浏览器仍需要单独部署到目标机器
+
+## 结论
+
+当前最稳妥的部署方式是：
+
+1. 在联网机器下载 Chromium
+2. 复制完整 `chromium-*` 目录
+3. 放到 `%APPDATA%\erpauto\ms-playwright\`
+4. 确保内部有 `chrome-win64\chrome.exe`
+
+只要满足这几个条件，ERPAuto 当前实现就能正确识别并使用浏览器。

+# 构建与发布流程
+
+本文档说明 ERPAuto Windows 便携版的当前构建与发布方式，包括推荐的一键发布命令、分步命令，以及发布产物在对象存储中的结构。
+
+## 概览
+
+当前发布链路分为 3 个阶段：
+
+1. 构建 Windows 包
+2. 生成本地发布物料和索引
+3. 上传到对象存储并校验远端索引
+
+现在已经提供一键总控脚本：
+
+```bash
+npm run release:publish -- --channel stable
+```
+
+或：
+
+```bash
+npm run release:publish -- --channel preview
+```
+
+## 发布前准备
+
+发布前需要确认：
+
+1. [package.json](/d:/FileLib/Projects/CodeMigration/ERPAuto/package.json) 和 [package-lock.json](/d:/FileLib/Projects/CodeMigration/ERPAuto/package-lock.json) 的版本号已经改到目标版本
+2. [config.yaml](/d:/FileLib/Projects/CodeMigration/ERPAuto/config.yaml) 中 `update` 配置正确，且对象存储可访问
+3. 对应版本的 changelog 已存在于 `docs/releases/`
+
+changelog 自动查找规则如下：
+
+1. 优先查找 `docs/releases/<version>-rebuild.md`
+2. 如果不存在，再查找 `docs/releases/<version>.md`
+
+例如当前版本是 `1.3.6`，脚本会按顺序尝试：
+
+```text
+docs/releases/1.3.6-rebuild.md
+docs/releases/1.3.6.md
+```
+
+## 推荐流程：一键发布
+
+### 发布 Stable
+
+```bash
+npm run release:publish -- --channel stable
+```
+
+### 发布 Preview
+
+```bash
+npm run release:publish -- --channel preview
+```
+
+这个命令会自动完成：
+
+1. 读取当前 `package.json` 版本号
+2. 校验 `package.json` / `package-lock.json` 版本一致
+3. 校验 changelog 文件存在
+4. 设置 `APP_CHANNEL`
+5. 执行 `build:win`
+6. 执行 `release:prepare`
+7. 执行 `release:upload --verify`
+8. 输出本次发布摘要
+
+## 分步流程
+
+如果需要调试，也可以手工分步执行。
+
+### 1. 构建
+
+Stable：
+
+```bash
+$env:APP_CHANNEL="stable"
+npm run build:win
+```
+
+Preview：
+
+```bash
+$env:APP_CHANNEL="preview"
+npm run build:win
+```
+
+### 2. 生成发布物料
+
+```bash
+npm run release:prepare -- --channel stable --changelog docs/releases/1.3.6.md
+```
+
+或：
+
+```bash
+npm run release:prepare -- --channel preview --changelog docs/releases/1.3.6.md
+```
+
+这一步会生成：
+
+- `release-output/updates/win-portable/<channel>/artifacts/...`
+- `release-output/updates/win-portable/<channel>/changelogs/...`
+- `release-output/updates/win-portable/<channel>/index.json`
+
+### 3. 上传并校验
+
+```bash
+npm run release:upload -- --channel stable --verify
+```
+
+或：
+
+```bash
+npm run release:upload -- --channel preview --verify
+```
+
+## 上传策略
+
+当前上传脚本默认采用“增量上传”：
+
+- 上传当前版本对应的 `artifact`
+- 上传当前版本对应的 `changelog`
+- 上传最新的 `index.json`
+
+也就是说，它不会再把旧版本的 exe 和旧 changelog 全部重复上传。
+
+如果确实需要整条通道做一次全量同步，可以显式使用：
+
+```bash
+npm run release:upload -- --channel stable --full-sync
+```
+
+## 对象存储目录结构
+
+发布到对象存储后的目录结构如下：
+
+```text
+updates/win-portable/
+├── stable/
+│   ├── artifacts/
+│   │   └── erpauto-<version>-stable-portable.exe
+│   ├── changelogs/
+│   │   └── <version>.md
+│   └── index.json
+└── preview/
+    ├── artifacts/
+    │   └── erpauto-<version>-preview-portable.exe
+    ├── changelogs/
+    │   └── <version>.md
+    └── index.json
+```
+
+## 相关脚本
+
+- [publish-release.js](/d:/FileLib/Projects/CodeMigration/ERPAuto/scripts/publish-release.js)
+  一键总控脚本，负责串起 build、prepare、upload。
+- [prepare-release.js](/d:/FileLib/Projects/CodeMigration/ERPAuto/scripts/prepare-release.js)
+  负责整理本地发布物料和生成 `index.json`。
+- [upload-release.js](/d:/FileLib/Projects/CodeMigration/ERPAuto/scripts/upload-release.js)
+  负责上传当前版本物料和 `index.json`，并可回读远端索引。
+- [compile-updater.js](/d:/FileLib/Projects/CodeMigration/ERPAuto/scripts/compile-updater.js)
+  负责构建原生 `portable-updater.exe`。
+
+## 常见问题
+
+### 1. 缺少 `--channel`
+
+会直接失败，因为发布必须显式指定 `stable` 或 `preview`。
+
+### 2. 找不到 changelog
+
+说明 `docs/releases/` 下没有当前版本对应的 Markdown 文件。  
+先补 changelog，再执行发布。
+
+### 3. 版本不是当前通道最新
+
+总控脚本在 `prepare` 后会检查本地生成的 `index.json`。  
+如果当前版本不是该通道索引的第一项，脚本会停止，避免把旧版本误当成当前发布版本。
+
+### 4. 只想调试某一步
+
+可以直接使用分步命令：
+
+- `npm run build:win`
+- `npm run release:prepare -- ...`
+- `npm run release:upload -- ...`
+
+## 建议
+
+日常发布优先使用：
+
+```bash
+npm run release:publish -- --channel <stable|preview>
+```
+
+只有在排查问题或需要特殊处理时，再退回分步命令。

+# ERPAuto 便携版自动更新说明
+
+## 概览
+
+当前实现的是一套面向 Windows 便携版的自定义更新系统，核心特点如下：
+
+- 基于 S3 兼容对象存储分发更新包
+- 按登录用户角色决定更新通道和行为
+- `User` 只跟随 `Stable`
+- `Admin` 同时可见 `Stable` 和 `Preview`
+- 更新包可后台下载，但安装必须由用户触发
+- 安装阶段使用独立的原生 `portable-updater.exe` 完成 exe 替换
+
+## 核心组件
+
+- 主进程更新服务
+  路径：[`src/main/services/update/update-service.ts`](/d:/FileLib/Projects/CodeMigration/ERPAuto/src/main/services/update/update-service.ts)
+- 更新规则工具
+  路径：[`src/main/services/update/update-utils.ts`](/d:/FileLib/Projects/CodeMigration/ERPAuto/src/main/services/update/update-utils.ts)
+- 更新 IPC
+  路径：[`src/main/ipc/update-handler.ts`](/d:/FileLib/Projects/CodeMigration/ERPAuto/src/main/ipc/update-handler.ts)
+- 前端更新弹窗
+  路径：[`src/renderer/src/components/UpdateDialog.tsx`](/d:/FileLib/Projects/CodeMigration/ERPAuto/src/renderer/src/components/UpdateDialog.tsx)
+- 前端更新入口
+  路径：[`src/renderer/src/App.tsx`](/d:/FileLib/Projects/CodeMigration/ERPAuto/src/renderer/src/App.tsx)
+- 原生更新器
+  路径：[`build/PortableUpdater.cs`](/d:/FileLib/Projects/CodeMigration/ERPAuto/build/PortableUpdater.cs)
+- 更新器编译脚本
+  路径：[`scripts/compile-updater.js`](/d:/FileLib/Projects/CodeMigration/ERPAuto/scripts/compile-updater.js)
+- 发布准备脚本
+  路径：[`scripts/prepare-release.js`](/d:/FileLib/Projects/CodeMigration/ERPAuto/scripts/prepare-release.js)
+- 发布上传脚本
+  路径：[`scripts/upload-release.js`](/d:/FileLib/Projects/CodeMigration/ERPAuto/scripts/upload-release.js)
+
+## 角色策略
+
+### `User`
+
+- 只读取 `stable/index.json`
+- 目标版本永远是最新 `Stable`
+- 如果当前客户端是 `Preview`，即使本地版本号更高，也会被视为“需要更新回稳定版”
+- 后台会自动下载推荐的 `Stable`
+- 用户点击后执行安装
+
+### `Admin`
+
+- 同时读取 `stable/index.json` 和 `preview/index.json`
+- 不自动下载
+- 只展示可选版本和更新说明
+- 由管理员手动选择版本并触发下载、安装
+
+## 当前安装包身份
+
+构建时会注入 `__APP_CHANNEL__`，用于标识当前客户端自身是 `stable` 还是 `preview`。
+
+这个值的作用非常关键：
+
+- 决定 `User` 是否需要从 `Preview` 洗回 `Stable`
+- 决定 `Admin` 当前处于哪条版本线
+- 决定更新弹窗中当前通道的展示
+
+相关声明：
+
+- [`src/shared/app-env.d.ts`](/d:/FileLib/Projects/CodeMigration/ERPAuto/src/shared/app-env.d.ts)
+- [`src/renderer/src/env.d.ts`](/d:/FileLib/Projects/CodeMigration/ERPAuto/src/renderer/src/env.d.ts)
+
+## 远端目录结构
+
+更新目录按通道分开：
+
+```text
+updates/win-portable/stable/index.json
+updates/win-portable/stable/artifacts/erpauto-<version>-stable-portable.exe
+updates/win-portable/stable/changelogs/<version>.md
+
+updates/win-portable/preview/index.json
+updates/win-portable/preview/artifacts/erpauto-<version>-preview-portable.exe
+updates/win-portable/preview/changelogs/<version>.md
+```
+
+`index.json` 的每个条目至少包含：
+
+- `version`
+- `channel`
+- `artifactKey`
+- `sha256`
+- `size`
+- `publishedAt`
+- `changelogKey`
+- `notesSummary`
+

+
+## 发布流程
+
+### 1. 构建
+
+```powershell
+$env:APP_CHANNEL="stable"
+npm run build:win
+```
+
+### 2. 准备发布目录
+
+```powershell
+node scripts/prepare-release.js --channel stable --changelog docs/releases/1.3.2-rebuild.md
+```
+
+### 3. 上传到对象存储
+
+```powershell
+npm run release:upload -- --channel stable --verify
+```
+
+## 发布流程图
+
+```mermaid
+flowchart TD
+  A[build:win] --> B[生成 dist/erpauto-portable.exe]
+  B --> C[prepare-release]
+  C --> D[复制 artifact]

+  C --> F[生成 index.json]
+  F --> G[release-upload]
+  G --> H[上传到对象存储]
+  H --> I[verify 远端 index.json]
+```
+
+## 版本排序规则
+
+为了避免“后发布低版本覆盖高版本”的问题，当前排序规则是：
+
+- 优先按版本号降序
+- 同版本再按 `publishedAt` 降序
+
+这条规则同时存在于：
+
+- [`src/main/services/update/update-utils.ts`](/d:/FileLib/Projects/CodeMigration/ERPAuto/src/main/services/update/update-utils.ts)
+- [`scripts/prepare-release.js`](/d:/FileLib/Projects/CodeMigration/ERPAuto/scripts/prepare-release.js)
+
+## 失败保护
+
+当前实现包含这些基本保护：
+
+- 缺失 `preview/index.json` 时，按空列表处理，不中断整体更新检查
+- 更新包下载完成后必须校验 `sha256`
+- `portable-updater.exe` 会等待旧进程退出和目标文件解锁
+- 替换前先备份旧 exe 为 `.bak`
+- 替换失败时尝试回滚
+
+## 当前已验证通过的能力
+
+- `1.3.1 -> 1.3.2` 的 `Stable` 发布链路已打通
+- 新分支实现能够成功构建 Windows 便携版
+- 原生 `portable-updater.exe` 能成功编译并被打包带入资源目录
+- 本地发布目录生成正常
+- 上传脚本可将更新包和索引发布到对象存储
+- 客户端真实升级流程已验证通过
+
+## 后续可继续优化的点
+
+- 将 `UpdateService` 进一步拆分，降低文件复杂度
+- 将日志策略区分成“正式日志”和“诊断日志”
+- 增加更多针对下载与安装阶段的单测
+- 将完整构建发布链路整理为一键化脚本
