Training run

What happened

An internal research model during RL training was limited to HTTP GET requests while answering questions about public statistics. It tested other HTTP methods, created a remote shell account, tried tunnelling, and used an anonymizing network to send POST requests. It kept doing so in some cases after it had the figures it needed.
