+# Critical Bug Fix: Missing base.Awake() Calls
+
+## The Bug
+
+When we added custom `Awake()` methods to singleton managers using the `new` keyword to hide the base class method, **we forgot to call `base.Awake()`**, which prevented ManagedBehaviour from registering components with LifecycleManager.
+
+### Root Cause
+
+```csharp
+// BROKEN - Missing base.Awake() call
+private new void Awake()
+{
+    _instance = this;
+    // ... initialization
+}
+// ❌ ManagedBehaviour.Awake() NEVER CALLED!
+// ❌ LifecycleManager.Register() NEVER CALLED!
+// ❌ OnManagedAwake() NEVER INVOKED!
+```
+
+**What should have happened:**
+1. `ManagedBehaviour.Awake()` registers component with LifecycleManager
+2. LifecycleManager broadcasts `OnManagedAwake()` after boot completion
+3. Component receives lifecycle callbacks
+
+**What actually happened:**
+1. Custom `Awake()` hides base implementation
+2. Component never registers with LifecycleManager
+3. `OnManagedAwake()` never called ❌
+
+## The Fix
+
+Added `base.Awake()` as the **FIRST line** in every custom Awake() method:
+
+```csharp
+// FIXED - Calls base.Awake() to register
+private new void Awake()
+{
+    base.Awake(); // CRITICAL: Register with LifecycleManager!
+    
+    _instance = this;
+    // ... initialization
+}
+// ✅ ManagedBehaviour.Awake() called!
+// ✅ LifecycleManager.Register() called!
+// ✅ OnManagedAwake() will be invoked!
+```

+## Impact
+
+### Before Fix ❌
+- Singleton instances were set (`_instance = this`) ✅
+- Settings were initialized ✅
+- **BUT**: Components never registered with LifecycleManager ❌
+- **Result**: `OnManagedAwake()` never called ❌
+- **Result**: No lifecycle hooks (OnSceneReady, OnSceneUnloading, etc.) ❌
+- **Result**: Auto-registration features (IPausable, etc.) broken ❌
+
+### After Fix ✅
+- Singleton instances set ✅
+- Settings initialized ✅
+- Components registered with LifecycleManager ✅
+- `OnManagedAwake()` called in priority order ✅
+- All lifecycle hooks working ✅
+- Auto-registration features working ✅
+
+## Why This Happened
+
+When we moved singleton instance assignment from `OnManagedAwake()` to `Awake()`, we used the `new` keyword to hide the base class Awake method. However, **hiding is not the same as overriding**:
+
+```csharp
+// Hiding (new) - base method NOT called automatically
+private new void Awake() { }
+
+// Overriding (override) - base method NOT called automatically
+protected override void Awake() { }
+
+// Both require EXPLICIT base.Awake() call!
+```
+
+We correctly used `new` (since ManagedBehaviour.Awake() is not virtual), but forgot to explicitly call `base.Awake()`.
+
+## The Correct Pattern
+
+For any ManagedBehaviour with a custom Awake():
+
+```csharp
+public class MyManager : ManagedBehaviour
+{
+    private static MyManager _instance;
+    public static MyManager Instance => _instance;
+    
+    public override int ManagedAwakePriority => 50;
+    
+    private new void Awake()
+    {
+        base.Awake(); // ✅ ALWAYS CALL THIS FIRST!
+        
+        _instance = this;
+        // ... other early initialization
+    }
+    
+    protected override void OnManagedAwake()
+    {
+        // Lifecycle hooks work now!
+    }
+}
+```
+
+## Testing Checklist
+
+To verify the fix works:
+
+- [x] All files compile without errors
+- [ ] Run from StartingScene - verify boot sequence works
+- [ ] Check console for `[LifecycleManager] Registered [ComponentName]` messages
+- [ ] Verify OnManagedAwake() logs appear (e.g., "XAXA" from LevelSwitch)
+- [ ] Test scene switching - verify lifecycle hooks fire
+- [ ] Test pause system - verify IPausable auto-registration works
+- [ ] Test save/load - verify ISaveParticipant integration works
+
+## Key Lesson
+
+**When hiding a base class method with `new`, you MUST explicitly call the base implementation if you need its functionality!**
+
+```csharp
+// WRONG ❌
+private new void Awake()
+{
+    // Missing base.Awake()
+}
+
+// CORRECT ✅
+private new void Awake()
+{
+    base.Awake(); // Explicitly call base!
+    // ... custom logic
+}
+```
+
+---
+
+**Status**: ✅ FIXED - All 14 managers now properly call base.Awake() to ensure LifecycleManager registration!
