Synthesis: Wargame Engine + Fabula Pattern

Layer What to Use Source
Rendering Wargame Engine’s node-tree viewport, scene system, GUI Wargame Engine (alive, 2024)
Integration pattern Client-server event protocol, visualization-agnostic world model Fabula (dead, 2012, conceptual only)
Save/load Both — Wargame handles visual state serialization, LangGraph checkpointer handles game state Combined
Input handling Wargame’s input system → serialized as events → dispatched to LangGraph Wargame for capture, Fabula pattern for dispatch
