 ## Phase 2: Basic Node Rendering
 Focus: Render tickets as nodes
 
 - [x] Task 2.1: Create node editor context
-    - WHERE: `src/gui_2.py` MMA dashboard
-    - WHAT: Begin/end node editor
-    - HOW:
-      ```python
-      ed.begin("Ticket DAG")
-      for ticket in self.track.tickets:
-       ed.begin_node(ticket.id)
-       imgui.text(ticket.id)

-    - HOW:
-      ```python
-      # Auto-layout: grid positions
-      col = i % 4
-      row = i // 4
-      ed.set_node_position(ticket.id, col * 200, row * 150)
-      ```

 ## Phase 3: Dependency Links
 Focus: Draw lines between nodes
 
 - [x] Task 3.1: Create links for dependencies

-    - HOW:
-      ```python
