 # 待测试
 
+- 画布生成配置节点的“生成配置/组装提示词”改为在节点下方打开独立输入浮层；浮层支持输入 `@` 从已连接图片、文本、视频、音频中选择引用，引用会以图片缩略图或文本标记展示，图片引用可放大预览；生成时再按当前引用解析为实际素材编号，不再提供或读取输入排序。
+- 图片节点悬浮工具栏新增“局部编辑”入口，打开后可在图片上用画笔/擦除工具绘制遮罩区域、填写局部修改要求，并通过图片编辑接口携带同尺寸 PNG mask 生成新图片节点；结果节点会放在原图右侧并自动连线，原图保持不变。
+- 图片节点悬浮工具栏新增“反推提示词”入口；点击后会在原图右侧创建包含反推预设提示词的文本节点，并继续创建一个已切到“文本”模式的生成配置节点，图片节点和文本节点都会自动连到该配置节点，配置节点会预填包含原图和文本节点引用的组装提示词并自动打开，用户可自行点击配置节点开始生成。
+- 图片节点悬浮工具栏新增“复制提示词”、“放大”和“超分”入口，并在末尾增加 `...` 更多按钮；点击“复制提示词”会复制生成该图片的提示词，图片没有提示词时会提示暂无可复制内容；点击 `...` 后打开 Ant Design 风格的“自定义工具栏”弹窗，可在图片节点占位上预览悬浮工具栏，信息、删除、存素材、下载、编辑和图片工具都在同一个快捷工具列表中勾选配置，并可切换是否显示按钮文字，保存后写入本地配置；`...` 配置入口固定显示，预览工具栏下方提供常驻横向滚动控制条。“放大”可在弹窗中选择 1K/2K/4K 目标像素和高清插值、双线性、最近邻算法，按原图比例生成新图片节点，已达到的目标像素会禁用并提示无需放大，最高不超过 4K；“超分”当前只打开暂未实现弹窗。
+- Canvas 资源节点会按当前生成上下文显示 `图片1`、`视频1`、`音频1`、`文本1` 角标；文本节点内容框和节点底部 prompt 面板输入 `@` 时应弹出已连接资源选择器，点击缩略图或文字可插入纯文本编号，并以蓝色 token 视觉高亮。
+- 文本节点连接到生成配置节点时，`@` 候选和实际生成输入应读取该生成配置节点的上游参考资源；生成配置输入统计区域应可拖动整个配置节点，预览按钮和设置控件仍保持可点击。
 - 配置弹窗改为“配置与用户偏好”并放大为可滚动弹窗；本地直连支持配置生图、视频、文本、音频四类可选模型列表和默认模型，新建画布生图和配置节点会读取“画布默认生图张数”，需要验证远程渠道和本地直连模型列表都能正确显示。
 - 画布音频节点底部生成面板改为音频提示词、音频模型下拉和 OpenAI Speech 参数设置，支持 `voice`、`response_format`、`speed`、`instructions` 并通过 `/audio/speech` 生成音频节点；需要验证本地直连和云端渠道的生成、重试、下载和刷新恢复。
 - 画布左上角菜单和右上角状态栏新增“文档”入口，会使用 `NEXT_PUBLIC_DOC_URL` 配置的地址并在新标签打开文档站；需要验证登录和未登录状态下顶部入口都可见。
