Lesson 4.1: The "Save Game" (Checkpointers)

Now that our graph has logic (Module 3) and short-term memory (Module 2), we face a new problem: Long-term Memory.

If you restart your script, the Python dictionary (State) is destroyed. The bot forgets who you are. To build a real application (like ChatGPT), you need to save the state to a database and reload it later.

What you will learn:

1. Checkpointers: The “Save Game” system.
2. Threads: How to separate User A from User B.
