 - `editor_project_icon.rs` 独立承接图标规范、图标 spritesheet、自动切片和手工拆分。普通图片模块只暴露可复用的 prompt builder 执行入口与强类型 provider 请求分流；nanobanana、无参考图 generation、有参考图 edit 的选择集中在同一个 helper，图标图集复用该 helper，不复制 provider 分支。
 - 图标规范生成的可选参考图与图标图集的必选主规范统一使用 `referenceId`，只接受当前 owner 的项目资源 ID 或账号素材 ID，不接受 objectKey、URL 或临时 key。SpacetimeDB `resolve_editor_reference_and_return` 因而只接收 `reference_id` 并按两张表主键查询，删除 `image_src` 二级索引。图标图集的普通附加参考图 `referenceImageSrcs` 仍允许 owned objectKey、项目资源 ID 或素材 ID，并继续走既有 owner 校验与真实图片下载链。
 - External v1 图标图集请求与 OpenAPI 同步改为必填 `referenceId`。前端和 Editor Agent 优先传正式 resource ID，其次传 asset ID；本地临时 ID、objectKey 和图片地址不得回退成主规范引用，未登记时明确失败并要求先上传或登记。
-- `resolve_editor_reference_and_return` 的歧义只在当前 owner 范围内判断：两张表先按 `owner_user_id` 过滤，同名但属于其它账号的行不阻断合法引用。记录存在 `asset_object_id` 时按该 ID 定位并同时核对 bucket、object key 与 owner，只有缺少 ID 的兼容旧行才按位置查询。图标规范入队 / inline 预检只验证这组行与对象元数据，最终共享图片执行器再下载一次参考图正文，避免同一引用在入队、worker 预检和生成阶段重复下载。
