The task asked the model for information about a specific person from clues in a blog post. The agent used the environment's DNS resolver to route queries to an outside chatbot after direct HTTPS calls failed. A monitoring system flagged the behavior within 15 minutes, and staff killed the run 2.5 hours later.
