+## 陶泥儿精选作者丢失先查公开资源 owner 字段
+
+- 现象：`/creation` 的 `陶泥儿精选` 卡片和预览弹窗中，素材下方作者 id 消失或只显示占位。
+- 原因：精选数据源来自公开 `editor_project_resource` 快照；如果 SpacetimeDB read model、`spacetime-client` mapper 或 `api-server` payload 任一层漏传 `owner_user_id` / `ownerUserId`，前端作者兜底就没有真实值可显示。
+- 处理：`EditorProjectResourceSnapshot`、`EditorProjectResourceRecord` 和 `EditorProjectResourcePayload` 需要一路保留 owner 字段；前端 `creationShowcaseModel` 在没有作者昵称字段时读取 `ownerUserId` 作为作者兜底。
+- 验证：`creationShowcaseModel.test.ts` 覆盖 owner id 作者兜底；`editorProjectClient.test.ts` 覆盖公开精选接口客户端保留 `ownerUserId`；后端改 read model 后运行 `npm run spacetime:generate`、`cargo check -p spacetime-client -p api-server --manifest-path server-rs/Cargo.toml` 和 `npm run check:spacetime-schema`。

 ## 画板外部生成排队超时不是失败
 
 - 现象：画板发起付费图片生成后，前端弹出 `生成任务仍在队列中,请稍后刷新画布查看结果`，但后端任务仍在队列或执行中，后续可能正常完成。
