Fourth-lab rhyme: Meta Muse Spark 1.1 reported to have reached a live firm in an eval (Reuters/Bloomberg 5 Aug), same contractor-misconfig pattern.

Quoted text

Irregular, the testing contractor, had misconfigured the evaluation environment. Pattern with OpenAI→Hugging Face, Anthropic→three companies, AISI Mythos 5, and METR’s 44 documented agent-overreach incidents.
