 - 2026-06-12 生成工具修正：移除拼图素材的生成图 mock 元数据，使其作为普通素材显示；底部生成工具改为先打开生成图片对话框，再进入生成中状态并把生成结果加入画布，生成结果保留元数据与修改入口。
 - 2026-06-13 真实生图修正：`/api/editor/images/generations` 和 `/api/editor/images/edits` 统一走 api-server VectorEngine `gpt-image-2` BFF；前端不再创建 mock 成功图，生成 / 修改失败会留在对话框内显示错误；生成图右上角 `{}` 元数据按钮可直接点击打开元数据窗口。
 - 2026-06-13 素材库修正：素材栏按文件夹分组，文件夹支持折叠和新建；上传入口可定向到当前文件夹，上传素材进入素材库并支持删除，内置素材只保留添加和重命名。
+- 2026-06-13 生图鉴权修正：编辑器工程和真实生图请求不再使用禁止 refresh 的局部鉴权策略，可通过 refresh cookie 静默补 access token；真实生图遇到 401 / 403 时弹窗显示“请先登录后再生成图片”，不再暴露后端 requestId 主文案。

 - 图片文件本体继续走 OSS，浏览器读取私有 generated 对象仍经 `/api/assets/read-url` 换签。
 - 资源表只保存资源元数据；图层位置、尺寸、缩放、层级和选中所需 ID 保存在 `editor_project` 的布局 JSON。
 - 前端不直接订阅 SpacetimeDB，统一通过 api-server 的 `/api/editor/projects*` BFF 读写。

+- 未登录用户可以使用本地演示态，但不触发工程自动保存；真实图片生成 / 修改需要登录。编辑器 API 请求允许使用 refresh cookie 静默补 access token，但 401 / 403 只在编辑器局部提示登录，不清空整站登录态，也不把后端 requestId 直接作为生图弹窗主文案。
