Symptom

After registering one more agent, the program never ends.

Evidence what you'll see

Cause

With one shared topic, each message from one agent triggers the other, which publishes again, and so on.

Fix steps

0 of 3 done

Step 1Map who publishes and who subscribes to each topic.
Step 2Give each agent its own topic, or add a stop condition (such as run_until) in the handler.
