+使用密钥 id_rsa 将代码上传到git

+_**Assistant**_
+
+<think><details><summary>Thought Process</summary>**Confirming SSH Configuration**
+
+I'm starting with verifying the SSH key's existence and configuration. Need to ensure `id_rsa` is present and properly set up before attempting any remote operations. This is the foundational step, and I will detail out the checks needed here.
+
+
+**Mapping the Workflow**
+
+\n\n
+
+Okay, I've formalized the plan to guide the user through the Git push. First, SSH key verification, then remote and branch checks. After that, I'll tackle staging and committing the files before pushing. I'm focusing on providing explicit instructions, especially regarding branch management. Listing files will help contextualize the project.

+
+好的，我将帮助您使用 `id_rsa` 密钥将代码上传到 Git 仓库。
+
+根据您提供的信息，上一次推送失败是因为本地没有 `main` 分支，而您试图推送 `main` 分支。当前您在 `master` 分支上。另外，您的项目中还有很多文件没有被 Git 跟踪。
+
+我将按照以下步骤操作：
+
+1.  **添加文件到暂存区**: 将所有项目文件添加到 Git 暂存区。
+2.  **提交文件**: 创建一个初始提交。
+3.  **推送到远程仓库**: 将本地的 `master` 分支推送到远程仓库 `origin`。
+
+我将先列出当前目录中的文件，以确保所有需要的文件都将被添加。

+# 图纸工作台 - 切分识别与编辑系统 (产品原型)
+
+这是一个用于产品功能展示的交互式前端原型，旨在模拟一个专业的图纸切分、识别与编辑平台的核心功能。
+
+该原型完全使用HTML、CSS和JavaScript（通过React库）构建，不包含任何后端服务或数据库，所有数据都存储在浏览器内存中，刷新页面会重置所有状态。
+
+## 核心功能
+
+- **层级结构管理**：在左侧树状视图中展示和操作件号的层级关系。
+- **图纸与表格预览**：在中间区域展示图纸背景、可拖拽的数据表格，并支持通过输入件号动态创建层级。
+- **数据编辑**：在右侧区域编辑选中件号的详细信息，父项的重量等数据会根据子项自动汇总计算。
+- **数据校验与导出**：实现了“保存”时的数据校验逻辑，以及模拟生成和下载 `.dxf` 文件的“导出”功能。
+
+## 如何预览
+
+因为这是一个纯静态项目，您不需要安装任何依赖（如Node.js, npm等）。您只需要一个现代浏览器（如Chrome, Firefox, Edge, Safari）即可。
+
+### 方法一：直接在浏览器中打开 (最简单)
+
+1.  在文件管理器中找到项目所在的文件夹。
+2.  直接双击 `index.html` 文件，或者将该文件拖拽到浏览器窗口中。
+
+### 方法二：通过本地Web服务器运行 (推荐)
+
+直接从文件系统打开HTML文件有时会因为浏览器的安全策略（CORS等）导致某些功能（如加载外部资源）出现问题。虽然本项目目前没有这类问题，但通过本地服务器预览是更专业、更可靠的方式。
+
+如果您安装了 Python (macOS 和大多数 Linux 发行版都已预装)，可以轻松启动一个本地服务器：
+
+1.  **打开终端 (Terminal)**。
+
+2.  **进入项目目录**：
+    ```bash
+    cd /path/to/your/project/cad编辑页面
+    ```
+    (请将 `/path/to/your/project/` 替换为实际的项目路径)
+
+3.  **启动服务器**：
+    - 如果您使用 Python 3:
+      ```bash
+      python3 -m http.server 8000
+      ```
+    - 如果您使用 Python 2:
+      ```bash
+      python -m SimpleHTTPServer 8000
+      ```
+
+4.  **在浏览器中访问**：
+    打开您的浏览器，并访问地址：[http://localhost:8000](http://localhost:8000)
+
+现在您应该能看到并与这个产品原型进行交互了。
