+
+- 背景：无源视频、音效、背景音乐和 UI 设计已经有 Agent/编辑器权威生成链路，资源自由画板顶部继续并列手动新建按钮会形成第二套普通用户入口，并挤占画布级操作空间。
+- 决策：资源自由画板顶部移除“生成视频”“生成音效”“生成背景音乐”和“新增 UI 设计”；保留播放、未完成编辑恢复、排序、复位，以及已有资源详情中的编辑、图片“生成动画”和精修图片“修改”。底层生成、恢复和事务能力不因入口移除而退役。
+- 验证：运行项目开发工作台与资源实时集成定向测试、AGC typecheck、编码检查和 `git diff --check`，并在桌面视口确认顶部无上述四个入口且画布级动作仍可见。

 - 图片资源新增“生成动画”派生入口：复用 `/api/external/v1/editor/character-animations/generations`（账号模式自动映射 `/api/editor/character-animations/generations`），以源图片的稳定 objectKey、真实宽高和固定 `seedance2.0-fast / 720p / same / 32帧 / 4秒` 参数提交；完成后下载 `previewVideoPath` 预览视频并以 `character-animation` 资源类型登记为本地 MP4/WebM 媒体，避免只保存首帧。

 - durable 账本新增 `remoteLegacyPublicPath` 字段（旧账本默认缺省），用于角色动画预览视频的换签下载与恢复；资源提交、轮询、下载、manifest 提交和恢复队列继续复用既有资源编辑事务链。
 - 资源编辑请求指纹纳入 `generationMode`，同一 `operationId` 换生成模式重试时不再按旧账本模式恢复；旧账本继续通过 legacy 指纹兼容。
