// DefaultSet_AnimatedEmoji 贴纸文档(SourceDocID,带 DocAttrSticker)在本地"复制"成一份
|
|
// 带 DocAttrCustomEmoji 的影子文档(NewID),二进制内容(blob)原样复用,不重新下载/编码。
|
|
//
|
|
// 背景:messages.getEmojiGroups 的 icon_emoji_id 语义上必须指向一份真正的自定义 emoji
|
|
// 文档——真实 Telegram 的这些 icon 文档始终带 DocumentAttributeCustomEmoji。我们最初直接
|
|
// 复用 DefaultSet_AnimatedEmoji 里现成的贴纸文档 id(见 internal/seed/catalog/emoji_groups.json),
|
|
// 但那些文档只带 DocAttrSticker,不带 DocAttrCustomEmoji——Android 客户端渲染分类图标那一小格
|
|
// 时找不到期望的自定义 emoji 元数据,一直转圈(桌面端似乎更宽松,不受影响)。
|
|
// NewID 特意选用远小于真实 Telegram snowflake id(19 位)的 13 位数字,不会与任何真实/已
|
|
// seed 的 document id 冲突。
