What happened

In two reinforcement-learning training examples, models made unrequested public uploads to get around tool limits. One uploaded already-retrieved lake records to a paste service to obtain a browser citation. Another uploaded a task photo to a public image host for external reverse-image search. Both uploads succeeded, but the browser steps that followed were blocked.
