+
+                                当前迁移范围：仅迁移数据去重（dedupe）、格式转换（convert）、数据拆分（split）三块处理逻辑到 Java；
+                                Python 桌面端壳、pywebview 调用方式、前端页面交互保持不变。
+
+                                建议联调顺序：
+                                1. 先启动 Java 后端；
+                                2. 在 Python 桌面端中选择文件并执行 dedupe/convert/split；
+                                3. Python 壳会先调用 /api/files/upload 上传临时文件；
+                                4. 再调用对应的 /api/dedupe/run、/api/convert/run、/api/split/run；
+                                5. Java 生成结果文件后，Python 壳再通过下载接口取回并保存到用户本地目录。
+
+                                本地启动说明：
+                                - 默认配置读取 application.yml；
+                                - 建议复制 application-local.example.yml 为本地配置，并在 IDE 中通过环境变量覆盖数据库与 OSS 参数；
