 ## 当前限制
 
 - Phase 1 是 Python-only。节点内部三个大文本框和更像 SD Prompt Reader 的图片预览 UI 留到 Phase 2 JS 前端增强。
 - 部分未知 custom conditioning 节点会返回 `PARTIAL` / unresolved，而不是猜测 prompt。
 - 某些 custom node 的运行结果如果没有写入 metadata 缓存，可能无法还原。
+- 如果放大图引用了原图，例如 `003.png`，但原图不存在于可解析路径中，会返回 `PARTIAL` / unresolved；插件无法凭空恢复运行时输出。
+- 插件不会全局扫描 workflow 中所有 `ShowText` / `widgets_values` / `text` 字段，只解析最终 selected sampler/generator 的 `positive` / `negative` 链路。
 - 被压缩或重新保存后丢失 metadata 的图片无法读取原始生成参数。

 ## Current Limitations
 
 - Phase 1 is Python-only. In-node large text boxes and a richer SD Prompt Reader style preview UI are planned for the Phase 2 JavaScript enhancement.
 - Some unknown custom conditioning nodes may return `PARTIAL` / unresolved instead of guessing.
 - If a custom node did not save its generated result into metadata cache, the parser may not be able to recover it.
+- If an upscaled image references its source image, such as `003.png`, and that source image is not present in a resolvable path, the parser returns `PARTIAL` / unresolved; it cannot recover runtime outputs from nowhere.
+- The plugin does not globally scan all `ShowText` / `widgets_values` / `text` fields in the workflow. It only resolves the final selected sampler/generator `positive` / `negative` chain.
 - Images with stripped metadata cannot provide original generation settings.
