 ## 代码结构
 
 ### 前端 (ui/)
-- `index.html` - 主界面，包含双操作按钮布局
-- `js/main.js` - 前端逻辑，约 740 行，包含：
-  - 拖放检测与区域判断
+- `index.html` - 主界面，包含双操作按钮布局、设置弹窗、更新弹窗
+- `js/main.js` - 前端逻辑（约 900 行），包含：
+  - 拖放检测与区域判断（通过按钮位置缓存 `cachedButtonRects`）
   - 动态批处理（基于 CPU 核心数）
   - 配置的保存/加载
-  - 日志系统（带数量限制和自动清理）
-- `css/style.css` - 主样式
-- `css/tailwind-custom.css` - Tailwind 自定义
+  - 日志系统（带数量限制和自动清理，最大 1000 条）
+  - 更新检查与下载
+- `css/style.css` - 主样式，包含 shadcn/ui CSS 变量、自定义按钮、弹窗动画
+- `css/main.css` - Tailwind 入口文件（需编译）
 
 ### 后端 (src-tauri/src/)
-- `main.rs` - 唯一的 Rust 源文件，包含所有 Tauri commands：
-  - `process_upx` - 执行压缩/解压
-  - `scan_folder` - 递归扫描 exe/dll 文件
-  - `get_upx_version` - 获取 UPX 版本
-  - `refresh_icon_cache` - 刷新 Windows 图标缓存
-  - `check_update` - 检查 GitHub 最新版本
-  - `save_config` / `load_config` - 配置持久化
+- `main.rs` - 唯一的 Rust 源文件（约 500 行），采用模块化结构：
+  - **数据结构定义**：`UpxOptions`、`ScanFolderOptions`、`AppConfig`、`UpdateInfo`
+  - **路径解析**：`get_upx_path()` 多级查找（安装版 → 开发版 → 便携版嵌入资源）
+  - **命令构建辅助**：`build_compress_args()`、`build_decompress_args()`
+  - **输出处理**：`filter_output_lines()`、`parse_upx_error()` 智能过滤和错误解析
+  - **Tauri Commands**：
+    - `process_upx` - 执行压缩/解压（支持 tokio 阻塞任务）
+    - `scan_folder` - 递归扫描 exe/dll 文件
+    - `get_upx_version` - 获取 UPX 版本
+    - `refresh_icon_cache` - 刷新 Windows 图标缓存
+    - `check_update` / `download_and_install` - 检查和下载 GitHub 更新
+    - `save_config` / `load_config` - 配置持久化
+
+### 构建配置
+- `src-tauri/tauri.conf.json` - Tauri 配置，定义窗口属性、权限、打包设置
+- `src-tauri/Cargo.toml` - Rust 依赖，release profile 优化（strip、lto、opt-level=z）
+- `.github/workflows/release.yml` - GitHub Actions 自动发布，生成 MSI、NSIS、Portable 三种安装包
 
 ## 重要细节
 
-### UPX 路径解析
-开发环境：`../upx/upx.exe`
-打包后：`_up_/upx/upx.exe`（相对于程序目录）
+### UPX 路径解析（三级查找）
+1. **安装版**：`程序目录/_up_/upx/upx.exe`
+2. **开发版**：`../upx/upx.exe`（相对于项目根目录）
+3. **便携版**：从嵌入的 `EMBEDDED_UPX` 释放到 `%TEMP%/upx-gui-portable/upx.exe`
 
 ### 编码处理
 UPX 在 Windows 上输出 GBK 编码，使用 `encoding_rs::GBK` 转换为 UTF-8

 最小 2，最大 16，默认为 CPU 核心数的 2 倍
 
+### 日志系统
+- 最大日志条数：1000 条
+- 超出时一次删除 200 条（批量删除优化性能）
+- 支持不同日志类型：`info`、`error`、`warning`、`success`、`hint`
+- 使用 `requestAnimationFrame` 优化滚动性能
+
 ### Tauri 2.0 特性
 - 使用 `window.__TAURI__` 全局对象（需启用 `withGlobalTauri: true`）
 - 命令调用：`invoke('command_name', { options })`
 - 拖放事件：`listen('tauri://drag-drop', handler)`
+- 权限通过 `capabilities` 定义（`main-capability`）
+
+### 错误处理模式
+后端使用模式匹配解析 UPX 输出，提供中文错误提示和解决方案：
+- `AlreadyPackedException` - 文件已加壳
+- `NotPackedException` - 文件未加壳
+- `CantPackException` - 无法压缩
+- `OverlayException` - 附加数据冲突

 ### 后端 (Rust)
 - 使用 `cargo fmt` 格式化
 - 使用 `cargo clippy` 检查代码质量
+- Release profile 已优化：`strip = true`、`lto = true`、`opt-level = "z"`
+
+### 界面风格
+- 基于 shadcn/ui New York 风格，使用 neutral 基色
+- 自定义字体：`YASLant`（回退到系统字体）
+- 禁用右键菜单、F5 刷新、Ctrl+W 等浏览器默认行为
+
+## 版本发布
+
+1. 修改 `src-tauri/Cargo.toml` 和 `package.json` 中的版本号
+2. 推送 tag：`git tag v1.x.x && git push origin v1.x.x`
+3. GitHub Actions 自动构建并发布 Release
+4. 生成三种安装包：
+   - `UPX-Tools-{version}-x64.msi` - MSI 安装包
+   - `UPX-Tools-{version}-x64-setup.exe` - NSIS 安装包
+   - `UPX-Tools-{version}-x64-portable.exe` - 便携版（单文件，内嵌 UPX）
