 ## Unreleased
 
++ [修复] 本地图片清理时保留生图与视频工作台历史引用的文件，避免生成记录仍在但图片丢失。
 + [修复] 画布将空格键专用于临时切换工具，避免按钮保留焦点后按空格被再次触发。
 + [优化] 画布默认改为拖动轻量虚线框选，虚线显示不受画布缩放影响，左下工具可切换选择与移动模式，并支持按住 Control 或空格临时反转当前模式。
 + [优化] 画布多图生成结果合并为单个图片节点，生成期间可展开查看每张图片的实时状态，优先展示最先成功的结果，并以紧凑堆叠展示已有图片。

 - Agent header tabs in English and Chinese at different panel widths; labels should collapse to icons and counts before either edge is clipped.
 - Agent message layout, Markdown, code blocks, attachments, token statistics, progress timelines, command groups, and scroll-follow behavior.
 - Prompt Center layout, source synchronization, search, asset insertion, prompt detail dialogs, and compact split-layout prompt pickers in the image and video workbenches.
+- Workbench history image cleanup: after generating content in the image or video workbench, deleting an asset, canvas image node, canvas content, or canvas project must not remove thumbnails, results, or references from generation history; deleting a generation record should still remove its dedicated local files.
 - Settings import/export, Volcengine Ark protocol handling, and WebDAV-related configuration.
 
 The Chinese version contains the complete item-by-item acceptance checklist.

 - Agent 工作目录指令：`canvas-agent/agent-instructions.md` 应作为独立维护源；重启 Canvas Agent 后，当前工作目录应自动生成 `AGENTS.md`；新建对话发送消息时，Codex 日志中的用户消息只包含本轮请求和必要的附件上下文，不再重复整段 Infinite Canvas 前置提示词，画布及工作台工具仍可正常调用。
 - 画布文本设置：文本节点和生成配置节点切换到文本模式后应显示推理强度设置，可选择自动、低、中、高、极高；选择自动时默认 OpenAI Responses 请求不应携带 `reasoning`，选择其他档位时应携带所选强度，刷新画布后节点设置应保留；文本模型自定义调用脚本应能读取 `reasoningEffort`，OpenAI 模板应按自动或指定档位正确组装请求。
 - 生图工作台参考图：将一张或多张图片拖入参考图区域后应直接上传并显示缩略图；拖入非图片文件应忽略，拖动过程中区域应显示高亮提示，放下文件不应导致浏览器打开或替换当前页面。
+- 工作台历史图片清理：生图或视频工作台生成内容后，在「我的素材」删除图片、删除画布图片节点、清空画布或删除画布，再次打开对应生成记录时，历史缩略图、结果图片和参考图仍应正常显示；删除生成记录时，其专属本地文件仍应正常清理。
 - 视频创作台参考资产：将图片、MP4/MOV 视频或 MP3/WAV 音频拖入任一参考资产区域后，应按文件类型自动上传到对应列表；当前拖入区域应显示高亮提示，原有数量、大小、时长和格式限制应继续生效。
 - 画布组装提示词：输入或连接超长提示词后，浮层正文高度不应继续撑大，内容应可在正文区域内滚动查看和编辑，标题及关闭按钮保持可见。
 - 画布节点提示词：图片等节点下方的提示词超过输入区域高度后，鼠标悬停在输入区域内滚动应查看提示词内容，不应缩放画布。
