Current decisions:\n\n在远端采集阶段，决定采用 **SFTP 15022** 端口作为默认传输协议，放弃旧版 FTP 15021。FTP 的被动模式会导致 WinError 10061 失效，虽然可以列出目录，但下载失败。\n\n目录识别方面，原先仅使用「[date]」模式来定位当天目录。由于服务器文件夹采用 **YYYY‑MM‑DD**（如 2026‑09‑18）的命名，导致误报为不存在。新的实现将同时尝试三种格式：\n- `{date}`\n- `[{date}]`\n- `({date})`\n一旦任一匹配即终止报错，提升了容错性。\n\n凭证使用已移入密码库（lookup_key = *commguard‑sftpgo‑jmomcuser1*），不在代码中硬编码。
