-**Why Build Fifth:**
-- Nearly all 3D games need physics utilities
-- Independent of complex game systems
-- Provides foundation for character controllers and interaction systems
-- Can be validated independently
-
-**Core Features:**
-```csharp
-// Raycast utilities
-public static class PhysicsUtils
-{
-    public static bool Raycast(Vector3 origin, Vector3 direction, float maxDistance,
-                              uint collisionMask = uint.MaxValue);
-    public static RaycastHit RaycastWithInfo(Vector3 origin, Vector3 direction, float maxDistance);
-    public static RaycastHit[] RaycastAll(Vector3 origin, Vector3 direction, float maxDistance);
-
-    // Shape casting
-    public static bool SphereCast(Vector3 origin, float radius, Vector3 direction, float maxDistance);
-    public static bool BoxCast(Vector3 origin, Vector3 size, Vector3 direction, float maxDistance);
-
-    // Overlap detection
-    public static Node3D[] OverlapSphere(Vector3 center, float radius, uint collisionMask);
-    public static Node3D[] OverlapBox(Vector3 center, Vector3 size, uint collisionMask);
-}
-
-// Physics materials management
-public class PhysicsMaterialManager : Node
-{
-    public void RegisterMaterial(string name, PhysicsMaterial material);
-    public PhysicsMaterial GetMaterial(string name);
-    public void ApplyMaterial(RigidBody3D body, string materialName);
-}
-
-// Trigger volume system
-public partial class TriggerVolume : Area3D
-{
-    [Signal] public delegate void BodyEnteredEventHandler(Node3D body);
-    [Signal] public delegate void BodyExitedEventHandler(Node3D body);
-
-    public bool IsBodyInside(Node3D body);
-    public Node3D[] GetBodiesInside();
-}
-```
-
-**Validation Game Ideas:**
-- Character that detects ground beneath them
-- Interaction system using raycasts
-- Trigger volumes that activate when player enters
-
 ### Phase 3: Character and Interaction Systems (Medium Priority)
 
 These systems focus on character control and world interaction, building upon the previously established libraries.
