It can be paused at any 'Checkpoint' (`Wait` node).\n2.  **The Async Portal (Bottom):** A state-management engine that remembers running processes and can 'teleport' new data to them."

Start Main Workflow` node.\n    - Observe the execution. It will run until `4. PAUSE at Checkpoint 1` and the status will change to **\"Waiting\"**. This is your paused process.\n\n3.  **Trigger the Teleport (Tab B):**\n    - Now, go to **Tab B** and click **\"Execute Workflow\"** on the *same* `1. Start Main Workflow` node.\n\n4.  **Observe the Magic:**\n    - The execution in **Tab B** will be very short. The Portal will detect an existing session and \"teleport\" its data.\n    - Instantly, the execution in **Tab A** will resume! It will pass Checkpoint 1, run through the `5a` and `5b` nodes, and then pause again at `6. PAUSE at Checkpoint 2`.\n\n5.  **Resume the Final Checkpoint (Tab B again):**\n    - In **Tab B**, click **\"Execute Workflow\"** one more time.\n\n6.  **Observe the Completion:**\n    - The execution in **Tab A** will now resume from Checkpoint 2 and run to completion.\n\n\nThis test proves how external events (from Tab B) can control and pass data to a long-running, paused process (in Tab A)."
