Transfer Seeds

传输种子是一套可移植的文件元数据系统，围绕三种侧车（sidecar）格式构建，用于跨网盘、跨用户、跨设备分享文件信息、离线秒传、备份释放空间。

• .oss（openlist-sharing-seed v1）：信息最完整的 JSON 格式，所有字段均可缺省。
• .torrent：标准 BitTorrent v1 文件，附带有 OpenList 扩展信息。
• .cas：与参考项目 OpenList-CAS 兼容的内容寻址载荷，用于天翼云秒传。

三者可以相互转换（在信息足够时），并支持生成、预览、秒传、离线下载、中转保存、编辑与重算。

Transfer Seeds are a portable file-metadata system built on three sidecar formats for sharing file information, offline rapid-upload, backup, and space release across drives, users, and devices.

• .oss (openlist-sharing-seed v1): the most complete JSON format; every field is optional.
• .torrent: a standard BitTorrent v1 file with OpenList extensions.
• .cas: a content-addressable payload compatible with the reference project OpenList-CAS, used for 189pc rapid upload.

The three formats convert between each other (when enough information is present) and support generation, preview, rapid upload, offline download, relayed save, editing, and recalculation.
