+
+// === Thread Safety Considerations ===
+
+// The --exec approach requires NO thread safety changes because:
+// 1. All scripts run in the same Python interpreter
+// 2. Scripts execute sequentially during initialization
+// 3. After initialization, only callbacks run (timer/input based)
+// 4. C++ maintains control of the render loop
+
+// This is the "honor system" - scripts must:
+// - Set up their callbacks/timers
+// - Return control to C++
+// - Not block or run infinite loops
+// - Use timers for periodic tasks
+
+// === Future Extensions ===
+
+// 1. Script communication via shared Python modules
+// game.py:
+//   import mcrfpy
+//   mcrfpy.game_state = {"level": 1, "score": 0}
+//
+// automation.py:
+//   import mcrfpy
+//   if mcrfpy.game_state["level"] == 1:
+//       # Test level 1 specific features
+
+// 2. Priority-based script execution
+// ./mcrogueface game.py --exec-priority high:critical.py --exec-priority low:logging.py
+
+// 3. Conditional execution
+// ./mcrogueface game.py --exec-if-scene menu:menu_test.py --exec-if-scene game:game_test.py
