- Failure details start with the error a failed child process ended with, so a shortened feedback keeps the cause
- Failure details: the promoted error line comes from the redacted log tails and loses terminal colours
- test: failure cause redaction and terminal controls

Subject: [PATCH 04/58] Test the Windows setup memory guard below, at and above
 each threshold

- Windows setup no longer stops at its first memory sample when little RAM was free at planning
- Keep the full 256 MiB stop point when the Windows setup memory budget is raised
- Test the running Windows setup monitor with a budget planned as zero

Subject: [PATCH 09/58] Name the stage a failed video worker stopped in, not
 the last planning snapshot

When the report carried no phase, the failure text took the label of the
last resource-planning snapshot as the stage, and the feedback form read
"after-encoding" as the encoding stage. The stage now comes from the
failed attempt itself, "generation" when it is not known, and planning
labels are shown only in the snapshot heading and never matched as a stage.

 3. **用 AI 全自动。** 打开“AI 全自动”，把想法交给 Agent，它会按镜头拆分、逐镜生成并拼接。耗时随镜头数和每镜时长而定，每镜按普通生成计时。

-      "Phone access: the phone page connects when phone access is switched on in the launcher, and also works on older phone browsers.",
-      "Queue: a single failed read of the queue no longer shows the connection lost card. The card appears after three failures in a row and goes away when the connection returns, and a running loop is kept through a short outage.",

+      "Model downloads: slow sources are retried with a longer time limit, and the last failure reason of each source and route is listed; when a source has problems, the launcher shows a dedicated card with a button to switch sources; the image model has its own download list with links and checksums, exported to a separate folder.",
+      "Failure messages: a failed video generation names the stage where it stopped (loading, sampling or decoding); failure feedback starts with the last error; automatic subtitles, subtitle downloads, media import and subtitle import in the editor state the reason when they fail, and GBK-encoded SRT subtitles can be imported; image generation, adding workflows and share export state when the disk is full; an unreadable queued reference image prompts for a different image; a failed part of a long video shows a short status, with details in the error card and the name of any missing file.",
+      "Generation: fixed an error when submitting a generation; when first/last frames and references cannot be combined, the failure card says which media to turn off; Generate with AI explains when the media list is full at 32 items; the estimate before generation marks first-time preparation, and a slow estimate gives a reason and a remedy; a queued request shows its wait in minutes or the number of requests ahead; a queued export shows Queued on its button; LoRA files in more naming styles are recognized, and an acceleration LoRA made for the original model gets its own explanation.",

+      "Memory and speed: when a Windows computer is refused only because of the default memory reserve, part of the reserve is used, keeping at least 1 GiB, so generation can start with about 5 GiB free; on computers with ample memory, consecutive requests skip reloading the models and run faster.",
