+## 2026-06-22 图片画布角色动作主媒体改为透明序列帧
+
+- 背景：角色动作生成后端已经在视频生成后抽取透明 PNG 帧并完成绿幕去背；画板继续把 `previewVideoPath` 当主媒体会让用户看到未扣绿幕视频，下载也拿不到可直接用于游戏素材的帧序列。
+- 决策：`/api/editor/character-animations/generations` 的上游预览视频继续保留为来源信息，但画板落层主类型固定为 `mediaType="image-sequence"`、`assetKind="character-animation"`；图层 `src` / `thumbnailSrc` 使用首帧，完整 `frames` 保存到 `imageSequenceFrames`，画布展示使用序列帧播放器循环播放。单图层下载生成序列帧 ZIP，画布素材 ZIP 中角色动作写入 `sequences/<编号-标题>/frames/`，不再把预览视频作为角色动作下载产物。
+- 影响范围：图片画布角色动作生成、画布图层快照、序列帧播放器、素材导出、角色动作设计文档和排障记忆。
+- 验证方式：运行角色动作图层工厂、画布展示、画布持久化、生成提交和素材导出相关前端测试，执行 `npm run typecheck`、`npm run check:encoding` 和 `git diff --check`。

 ## 2026-06-21 图片画布生成完成态由后端写入画布布局
 
 - 背景：图片画布角色形象等长耗时生成在服务端完成后，如果浏览器已刷新或原 HTTP 回调丢失，前端无法再把生成结果图层和 `generation-dialog` 完成态写回 `editor_canvas.layers_json`，用户会继续看到“生成中”卡片。

-## 图片画布角色动作结果不能把首帧当主媒体
+## 图片画布角色动作结果主类型是序列帧
 
-- 现象：画板里 `生成角色动作` 返回后显示成一张不可播放图片，点击下载或素材 ZIP 导出时拿到的也是 PNG，而不是动作视频。
-- 原因：后端已经生成 `previewVideoPath`，并继续执行抽帧、绿幕去背和帧素材 OSS 落盘；前端落层时却把 `frames[0].imageSrc` 当作图层主 `src`，且没有设置 `mediaType: "video"`，导致预览和导出都按图片处理。
-- 处理：角色动作结果图层主 `src` 必须使用 `previewVideoPath`，`mediaType` 固定为 `video`，`assetKind` 固定为 `character-animation`；首帧透明 PNG 只写入 `thumbnailSrc`，用于 `<video poster>` 和后续动作素材二次生成源。不得移除后端原有视频生成、抽帧、绿幕去背和帧落盘流程。
-- 验证：`ImageCanvasGenerationLayerModel` 应断言动作结果 `src` 为预览视频且 `thumbnailSrc` 为首帧；画布集成测试应出现 `<video controls poster=...>`；导出模型应按 `mediaType="video"` 输出 mp4/webm/mov 等真实视频扩展名。
+- 现象：产品要求画板 `生成角色动作` 返回后按透明序列帧播放和下载，但旧实现或旧测试可能继续把结果当作预览视频处理。
+- 原因：后端仍需要先生成 `previewVideoPath` 再抽帧、绿幕去背和落 OSS；如果前端把预览视频当主媒体，就会绕过已经扣绿幕的 PNG 帧，也无法按序列帧打包下载。
+- 处理：角色动作结果图层主 `src` 使用 `frames[0].imageSrc`，`mediaType` 固定为 `image-sequence`，`assetKind` 固定为 `character-animation`，完整帧列表写入 `imageSequenceFrames`，`previewVideoPath` 只作为来源信息保留。单图层下载必须生成序列帧 ZIP；画布素材 ZIP 中角色动作写入 `sequences/<编号-标题>/frames/`。不得移除后端原有视频生成、抽帧、绿幕去背和帧落盘流程。
+- 验证：`ImageCanvasGenerationLayerModel` 应断言动作结果 `src` 为首帧且 `mediaType="image-sequence"`；画布集成测试应出现 `画布序列帧：角色动作` 图片播放器，不应出现角色动作 `<video>`；导出测试应断言角色动作下载和画布素材导出都包含序列帧 ZIP / frames 目录。
