 - 能力分流：SVG/文本/代码走结构化 LLM 内容派生与格式复核；视频使用源视频稳定引用；音效/BGM 因现役接口无源音频字段，固定定义为基于源语义的派生重制，不能宣称波形级编辑；项目版本追加子版本。
 - 信任边界：前端能力提示不是授权事实，Tauri 在提交前按 manifest、已完成任务或上传登记重新核验来源并复核项目 revision / 源内容摘要。远端生成继续使用稳定幂等身份、`202` 轮询与稳定 object/resource/asset 身份，签名 URL 不落 manifest。
 - 队列与结果边界：登录态媒体派生统一使用 `game-creator-resource-editor` 专用消费身份；图片 refine、视频、音效和 BGM 复用同一逻辑请求的稳定 `Idempotency-Key`，路由不得丢弃。完成结果只返回裁剪后的稳定 object/resource/asset 引用与必要媒体元数据，不暴露 provider、worker、队列内部字段或临时签名 URL。
+- 验证边界：资源投影回归必须把已完成任务在 `artifacts` 中明确登记的音频归入音乐音效资源，同时继续排除未登记音频和未知二进制；画布工具栏数量断言必须与全部现役工具清单同步；文本预览回归必须覆盖 HTML 与现役代码扩展名；委派回执测试应在显式进入等待态前完成同 action 幂等断言，避免后台 parent-wake 与断言竞争。
