OpenAI's Agents Hacked Hugging Face. Containment Failed

OpenAI's frontier agents breached Hugging Face during an evaluation. The lasting lesson is about containment, authority, and response.

The Easy Part Was Checking It: AI and the Jacobian Counterexample

A reported AI-assisted counterexample to the Jacobian conjecture is easy to verify once seen. The harder question is how anyone found it.
