+## 图片画布快速编辑模型必须在后端选择正确的 provider 协议
+
+- 现象：快速编辑继承或选择 `nanobanana2` 后，上游返回 `not supported model for image generation`；图集开放快速编辑后尤其容易触发。
+- 原因：前端把 `gemini-3.1-flash-image-preview` 正常提交到 `/api/editor/images/edits`，但后端无条件使用只支持 `gpt-image-2` 的 VectorEngine `/v1/images/edits` multipart 协议。
+- 处理：快速编辑请求同时提交 `model / aspectRatio / imageSize`。api-server 归一模型后分流：`nanobanana2` 使用 `/v1beta/models/{model}:generateContent`，把原图和参考图放入 `inline_data`，并传递 `generationConfig.imageConfig`；`gpt-image-2` 继续使用 `/v1/images/edits` multipart 和 16 像素 provider 边界对齐。nanobanana2 保留 provider 输出几何尺寸，不套用 GPT edits 的像素恢复。
+- 验证：`npm run test -- src/services/image-editor/editorProjectClient.test.ts src/components/image-editor/useImageCanvasGenerationSubmissionWorkflow.test.tsx` 覆盖前端参数提交；`cargo test -p api-server editor_image_edit --manifest-path server-rs/Cargo.toml` 覆盖模型分流、尺寸档位计费与 GPT 对齐恢复。

 ## 图片画布纯尺寸变换必须先在内存决策再单次上传
 
 - 现象：`nanobanana2` 已返回并成功解码图片，任务随后报“尺寸无效”；普通生图若把尺寸恢复作为硬失败，provider 已成功回图后仍可能没有素材进入素材库和画布。
