+# ManagedBehaviour System - Architecture Overview
+
+**Version:** 2.0 <br>
+**Updated:** 11.11.2025
+
+
+---
+
+## What is the ManagedBehaviour System?
+
+Lifecycle orchestration framework that provides guaranteed execution order and deterministic lifecycle management for Unity components.
+
+### Problems Solved
+
+We've had quite a few things shoe-stringed together in various ways and dependant on references to each other.
+Due to undefined initialization order - null references during access to yet uninitialized resources was becoming a problem.
+
+### What You Get
+
+- **Guaranteed Initialization Order** - Managers ready before components that depend on them
+- **Deterministic Lifecycle Hooks** - Predictable callbacks at key moments
+- **Automatic Registration** - No boilerplate for wiring up systems
+- **Scene Lifecycle Events** - Built-in hooks for scene load/unload
+- **Save/Load Coordination** - Centralized collection of save data
+- **Bootstrap Integration** - Components know when bootstrap completes  
+
+---
+
+## Architecture Principles
+
+### 1. Centralized Orchestration
+
+Single `LifecycleManager` singleton coordinates all lifecycle events. Components auto-register and receive callbacks at appropriate times.
+
+### 2. Sealed Framework Methods
+
+`Awake()` and `OnDestroy()` are sealed. Use `OnManagedAwake()` and `OnManagedDestroy()` instead. Prevents forgetting to call `base.Awake()`.
+
+### 3. Two-Phase Initialization
+
+- **Early (`OnManagedAwake()`)**: During Unity's Awake, before bootstrap. Use for singleton setup.
+- **Late (`OnManagedStart()`)**: After bootstrap completes. All managers guaranteed ready.
+
+### 4. Registration Order Execution
+
+Execution follows Unity's natural Awake order. No priority numbers to manage.
+
+### 5. Automatic Cleanup
+
+Framework handles unregistration automatically. Override `OnManagedDestroy()` only if you need custom cleanup.
+
+---
+

+### Boot Sequence

+
+## Class Diagram
+
+![Class Diagram](../media/class_diagram.png)
+
+---
+## Key Guarantees
+
+### Guaranteed
+
+1. **Bootstrap Completion** - `OnManagedStart()` always fires after bootstrap completes
+2. **Manager Availability** - All manager singletons exist when `OnManagedStart()` is called
+3. **Scene Lifecycle** - `OnSceneReady()` fires after scene load, `OnSceneUnloading()` before unload
+4. **Automatic Registration** - Can't forget to register (Awake is sealed)
+5. **Automatic Cleanup** - Can't forget to unregister (OnDestroy is sealed)
+6. **Save/Load Coordination** - All save participants called in one pass
+
+### Not Guaranteed
+
+1. **Initialization Order Between Components** - `OnManagedAwake()` follows Unity's unpredictable Awake order
+2. **Thread Safety** - All methods must run on main thread
+3. **Performance** - Broadcasting to 1000+ components may have overhead
+4. **SaveId Uniqueness** - Developer responsible for unique SaveIds

+# ManagedBehaviour System - Technical Reference
+
+**Version:** 2.0 <br>
+**Updated:** 11.11.2025
+
+---
+
+## Overview
+
+The ManagedBehaviour system provides a deterministic, ordered lifecycle management framework for Unity MonoBehaviours. This document provides complete technical documentation of all classes, methods, and APIs.
+
+---
+
+## Core Classes
+
+### ManagedBehaviour (Abstract Base Class)
+
+**Namespace:** `Core.Lifecycle`  
+**Inherits:** `MonoBehaviour`  
+**Location:** `Assets/Scripts/Core/Lifecycle/ManagedBehaviour.cs` → [View Source](../../Assets/Scripts/Core/Lifecycle/ManagedBehaviour.cs)
+
+Abstract base class that all managed components must inherit from. Provides automatic registration with LifecycleManager and ordered lifecycle callbacks.
+
+#### Lifecycle Hook Methods
+
+Override these `internal virtual` methods to customize component behavior at different lifecycle stages. Called automatically by `LifecycleManager`.
+
+<details>
+<summary>Click to see more details</summary>
+
+##### `OnManagedAwake()`
+```csharp
+internal virtual void OnManagedAwake()
+```
+**Called:** During registration (within Unity's Awake phase)  
+**Execution Order:** Natural Unity script execution order (not guaranteed between components)  
+**Use For:**
+- Setting singleton instances (`_instance = this`)
+- Early GetComponent calls
+- One-time initialization that doesn't depend on other systems
+
+**Timing Guarantees:**
+- ✅ GameObject and component exist
+- ✅ Scene is loaded
+- ❌ Other components may not be initialized yet
+- ❌ Bootstrap may not be complete
+
+##### `OnManagedStart()`
+```csharp
+internal virtual void OnManagedStart()
+```
+**Called:** After bootstrap completes (for boot components) or immediately after registration (for late-registered components)  
+**Execution Order:** Registration order  
+**Use For:**
+- Initialization that depends on other managers
+- Accessing singleton instances safely
+- Setting up cross-system dependencies
+
+**Timing Guarantees:**
+- ✅ All managers are initialized
+- ✅ Bootstrap resources are available
+- ✅ Safe to access `GameManager.Instance`, `AudioManager.Instance`, etc.
+
+##### `OnSceneUnloading()`
+```csharp
+internal virtual void OnSceneUnloading()
+```
+**Called:** Before scene unload  
+**Execution Order:** Registration order  
+**Use For:**
+- Scene-specific cleanup
+- Saving temporary scene state
+
+**Timing Guarantees:**
+- ✅ Scene is still loaded
+- ✅ Other components in scene still exist
+
+##### `OnSceneReady()`
+```csharp
+internal virtual void OnSceneReady()
+```
+**Called:** After scene load completes  
+**Execution Order:** Registration order  
+**Use For:**
+- Scene-specific initialization
+- Finding scene objects
+- Setting up scene-specific state
+
+**Timing Guarantees:**
+- ✅ All scene GameObjects are loaded
+- ✅ Batched components have received `OnManagedStart()`
+
+##### `OnSceneSaveRequested()`
+```csharp
+internal virtual string OnSceneSaveRequested()
+```
+**Called:** Before scene unload during scene transitions  
+**Returns:** Serialized scene-specific data (JSON string), or `null` if nothing to save  
+**Use For:**
+- Level progress
+- Object positions
+- Puzzle states
+- Temporary scene data
+
+**⚠️ Important:** Must return synchronously.
+
+##### `OnSceneRestoreRequested(string serializedData)`
+```csharp
+internal virtual void OnSceneRestoreRequested(string serializedData)
+```
+**Called:** After scene load, during `OnSceneReady` phase  
+**Parameters:**
+- `serializedData` - Previously saved data from `OnSceneSaveRequested()`
+
+**Use For:**
+- Restoring level progress
+- Setting object positions
+- Restoring puzzle states
+
+**⚠️ Important:** Must execute synchronously. Do not use coroutines or async/await.
+
+##### `OnSceneRestoreCompleted()`
+```csharp
+internal virtual void OnSceneRestoreCompleted()
+```
+**Called:** After all `OnSceneRestoreRequested()` calls complete  
+**Timing:** Always called after scene load, whether save data exists or not  
+**Use For:**
+- Post-restore initialization
+- First-time initialization (when no save data exists)
+- Triggering events after state is restored
+
+**Common Pattern:**
+```csharp
+internal override void OnSceneRestoreCompleted()
+{
+    if (!_hasPlayed) // Check if this is first time
+    {
+        PlayIntroAudio();
+        _hasPlayed = true;
+    }
+}
+```
+
+##### `OnGlobalSaveRequested()`
+```csharp
+internal virtual string OnGlobalSaveRequested()
+```
+**Called:** Once before save file is written to disk  
+**Returns:** Serialized global persistent data (JSON string), or `null`  
+**Use For:**
+- Player inventory
+- Unlocked features
+- Card collections
+- Persistent progression
+
+**Timing:** Called once per game save (not per scene transition)
+
+##### `OnGlobalRestoreRequested(string serializedData)`
+```csharp
+internal virtual void OnGlobalRestoreRequested(string serializedData)
+```
+**Called:** Once on game boot after save file is read  
+**Parameters:**
+- `serializedData` - Previously saved data from `OnGlobalSaveRequested()`
+
+**Use For:**
+- Restoring player inventory
+- Restoring unlocked features
+- Restoring persistent progression
+
+**Timing:** Called once on boot, not during scene transitions
+
+##### `OnGlobalLoadCompleted()`
+```csharp
+internal virtual void OnGlobalLoadCompleted()
+```
+**Called:** Once on game boot after all global restore operations complete  
+**Use For:**
+- Triggering UI updates after load
+- Broadcasting load events
+- Post-load initialization
+
+##### `OnGlobalSaveStarted()`
+```csharp
+internal virtual void OnGlobalSaveStarted()
+```
+**Called:** Once before save file is written  
+**Use For:**
+- Final validation before save
+- Cleanup operations before save
+
+##### `OnManagedDestroy()`
+```csharp
+internal virtual void OnManagedDestroy()
+```
+**Called:** During `OnDestroy`, before unregistration  
+**Execution Order:** Registration order  
+**Use For:**
+- Unsubscribing from events
+- Releasing resources
+- Custom cleanup logic
+
+**Note:** Most cleanup is automatic (auto-registrations are handled by framework).

+Virtual properties that control automatic behaviors like pause registration and save system participation.
+
+<details>
+<summary>Click to see more details</summary>
+
+##### `AutoRegisterPausable`
+```csharp
+public virtual bool AutoRegisterPausable => false;
+```
+**Type:** `bool`  
+**Default:** `false`  
+**Description:** If true and component implements `IPausable`, automatically registers with `GameManager.Instance` during initialization. Automatic unregistration occurs on destruction.
+
+##### `AutoRegisterForSave`
+```csharp
+public virtual bool AutoRegisterForSave => false;
+```
+**Type:** `bool`  
+**Default:** `false`  
+**Description:** If true, component participates in the save/load system. Should override `OnSceneSaveRequested()` and `OnSceneRestoreRequested()` or global equivalents.
+
+##### `SaveId`
+```csharp
+public virtual string SaveId { get; }
+```
+**Type:** `string`  
+**Default:** `"{SceneName}/{GameObjectName}/{ComponentType}"`  
+**Description:** Unique identifier for this component in the save system. Cached on first access for performance. Override for singletons (e.g., `"PlayerController"`) or custom IDs.
+
+**⚠️ Warning:** GameObject name changes at runtime will NOT update the cached SaveId.

+
+## Summary
+
+**ManagedBehaviour in 3 Sentences:**
+
+Inherit from `ManagedBehaviour` to get automatic lifecycle management with guaranteed initialization order. Use `OnManagedStart()` to safely access manager singletons, and use built-in save/load hooks for persistence. The framework handles registration and cleanup automatically - you just override the hooks you need.
+
+**When to Use:**
+- ✅ Singleton managers
+- ✅ Components that access managers
+- ✅ Components that need save/load
+- ✅ Components that need scene lifecycle events
+
+**When to Skip:**
+- ❌ Simple self-contained components
+- ❌ Third-party code (can't change base class)
+- ❌ Performance-critical code with no dependencies
+
+**But can I still use regular MonoBehaviour?!** <br>
+_Yes!_ Only use ManagedBehaviour when you need its features (manager access, save/load, etc.)
+
+
+---
+
+## Lifecycle Methods Summary
+
+1. **OnManagedAwake()** - Called during Unity's Awake phase; use for **internal setup** and GetComponent calls.
+2. **OnManagedStart()** - Called after bootstrap completes; **safe to access** manager singletons.
+3. **OnSceneReady()** - Called after scene finishes loading; use for scene-specific initialization.
+4. **OnSceneUnloading()** - Called before scene unloads; use for scene cleanup.
+5. **OnSceneSaveRequested()** - Returns serialized scene-specific data before scene transitions.
+6. **OnSceneRestoreRequested(data)** - Receives saved scene data after scene loads.
+7. **OnSceneRestoreCompleted()** - Called after all scene restore operations complete.
+8. **OnGlobalSaveRequested()** - Returns serialized persistent data when game saves.
+9. **OnGlobalRestoreRequested(data)** - Receives persistent data on game boot.
+10. **OnGlobalLoadCompleted()** - Called after all global restore operations complete on boot.
+11. **OnGlobalSaveStarted()** - Called before save file is written; use for pre-save validation.
+12. **OnManagedDestroy()** - Called during OnDestroy; use for cleanup and event unsubscription.

+
+## Quick Reference - Common Use Cases
+
+### Access Manager Singleton Safely
+```csharp
+internal override void OnManagedStart()
+{
+    GameManager.Instance.DoSomething(); // Safe - managers guaranteed ready
+}
+```
+
+### Create Singleton Manager
+```csharp
+private static MyManager _instance;
+public static MyManager Instance => _instance;
+
+internal override void OnManagedAwake()
+{
+    _instance = this;
+}
+```
+
+### Save Scene Progress
+```csharp
+public override bool AutoRegisterForSave => true;
+
+internal override string OnSceneSaveRequested()
+{
+    return JsonUtility.ToJson(myData);
+}
+
+internal override void OnSceneRestoreRequested(string data)
+{
+    myData = JsonUtility.FromJson<MyData>(data);
+}
+```
+
+### Auto-Register as Pausable
+```csharp
+public class MyComponent : ManagedBehaviour, IPausable
+{
+    public override bool AutoRegisterPausable => true;
+    
+    public void Pause() { /* pause logic */ }
+    public void Resume() { /* resume logic */ }
+}
+```
+
+### Scene-Specific Initialization
+```csharp
+internal override void OnSceneReady()
+{
+    FindObjectsInScene();
+    InitializeLevel();
+}
+```
+
+### Cleanup on Destroy
+```csharp
+internal override void OnManagedDestroy()
+{
+    EventBus.OnSomething -= HandleEvent;
+}
+```
+
+---
+
+## Getting Started Examples
+
+### 1. Basic Component
+
+```csharp
+using Core.Lifecycle;
+
+public class MyComponent : ManagedBehaviour
+{
+    internal override void OnManagedAwake()
+    {
+        // Early initialization (singleton setup, GetComponent)
+        Debug.Log("MyComponent awakened");
+    }
+
+    internal override void OnManagedStart()
+    {
+        // Late initialization (safe to access managers)
+        Debug.Log("MyComponent started - managers are ready");
+    }
+}
+```
+
+### 2. Singleton Manager
+
+```csharp
+using Core.Lifecycle;
+
+public class MyManager : ManagedBehaviour
+{
+    private static MyManager _instance;
+    public static MyManager Instance => _instance;
+
+    internal override void OnManagedAwake()
+    {
+        _instance = this; // Set singleton early
+    }
+
+    internal override void OnManagedStart()
+    {
+        // All other managers are ready here
+        AudioManager.Instance.PlaySound("ManagerReady");
+    }
+}
+```
+
+### 3. Component with Save/Load
+
+```csharp
+using Core.Lifecycle;
+
+public class PuzzleComponent : ManagedBehaviour
+{
+    public override bool AutoRegisterForSave => true;
+    public override string SaveId => "MyPuzzle"; // Custom ID
+    
+    private bool _isSolved;
+
+    internal override string OnSceneSaveRequested()
+    {
+        return JsonUtility.ToJson(new { isSolved = _isSolved });
+    }
+
+    internal override void OnSceneRestoreRequested(string data)
+    {
+        var saveData = JsonUtility.FromJson<SaveData>(data);
+        _isSolved = saveData.isSolved;
+    }
+
+    [System.Serializable]
+    private class SaveData
+    {
+        public bool isSolved;
+    }
+}
+```
+
+### 4. Component with Cleanup
+
+```csharp
+using Core.Lifecycle;
+
+public class EventSubscriber : ManagedBehaviour
+{
+    internal override void OnManagedStart()
+    {
+        GameManager.Instance.OnGamePaused += HandlePause;
+    }
+
+    internal override void OnManagedDestroy()
+    {
+        // Automatic cleanup
+        if (GameManager.Instance != null)
+            GameManager.Instance.OnGamePaused -= HandlePause;
+    }
+
+    private void HandlePause() { }
+}
+```
+
+---
+
+## Detailed Use Cases
+
+### Use Case 1: Accessing Singleton Managers Safely
+
+**Problem:** Accessing `GameManager.Instance` in `Awake()` might fail if GameManager hasn't initialized yet.
+
+**Solution:**
+```csharp
+public class Player : ManagedBehaviour
+{
+    // ❌ DON'T: Risky in OnManagedAwake (managers may not be ready)
+    internal override void OnManagedAwake()
+    {
+        // var settings = GameManager.Instance.GetSettings(); // RISKY!
+    }
+
+    // ✅ DO: Safe in OnManagedStart (managers guaranteed ready)
+    internal override void OnManagedStart()
+    {
+        var settings = GameManager.Instance.GetSettings(); // SAFE!
+        ApplySettings(settings);
+    }
+}
+```
+
+---
+
+### Use Case 2: Scene-Specific Initialization
+
+**Problem:** Need to initialize something after a scene finishes loading.
+
+**Solution:**
+```csharp
+public class LevelManager : ManagedBehaviour
+{
+    internal override void OnSceneReady()
+    {
+        // Scene is fully loaded, all objects exist
+        FindObjectiveMarkers();
+        SpawnEnemies();
+        PlayLevelMusic();
+    }
+}
+```
+
+---
+
+### Use Case 3: Saving Player Progress
+
+**Problem:** Need to save level progress when transitioning between scenes.
+
+**Solution:**
+```csharp
+public class LevelProgress : ManagedBehaviour
+{
+    public override bool AutoRegisterForSave => true;
+    public override string SaveId => "LevelProgress";
+    
+    private int _checkpointIndex;
+    private float _timeElapsed;
+
+    internal override string OnSceneSaveRequested()
+    {
+        return JsonUtility.ToJson(new 
+        { 
+            checkpoint = _checkpointIndex,
+            time = _timeElapsed 
+        });
+    }
+
+    internal override void OnSceneRestoreRequested(string data)
+    {
+        var save = JsonUtility.FromJson<SaveData>(data);
+        _checkpointIndex = save.checkpoint;
+        _timeElapsed = save.time;
+    }
+
+    internal override void OnSceneRestoreCompleted()
+    {
+        // Restore complete, trigger UI update
+        UpdateProgressUI();
+    }
+}
+```
+
+---
+
+### Use Case 4: Global Persistent Data (Inventory)
+
+**Problem:** Need to save player inventory across all scenes.
+
+**Solution:**
+```csharp
+public class InventoryManager : ManagedBehaviour
+{
+    public override bool AutoRegisterForSave => true;
+    public override string SaveId => "Inventory";
+    
+    private List<string> _items = new List<string>();
+
+    internal override string OnGlobalSaveRequested()
+    {
+        // Save to global save file (not scene-specific)
+        return JsonUtility.ToJson(new { items = _items });
+    }
+
+    internal override void OnGlobalRestoreRequested(string data)
+    {
+        // Restore from global save file on boot
+        var save = JsonUtility.FromJson<SaveData>(data);
+        _items = new List<string>(save.items);
+    }
+
+    internal override void OnGlobalLoadCompleted()
+    {
+        // All global data loaded, safe to initialize UI
+        RefreshInventoryUI();
+    }
+}
+```
+
+---
+
+### Use Case 5: Auto-Registering as Pausable
+
+**Problem:** Component implements `IPausable` and needs to register with `GameManager`.
+
+**Solution:**
+```csharp
+public class AnimatedCharacter : ManagedBehaviour, IPausable
+{
+    public override bool AutoRegisterPausable => true;
+    
+    // IPausable implementation
+    public void Pause()
+    {
+        // Pause animations
+    }
+
+    public void Resume()
+    {
+        // Resume animations
+    }
+}
+// No manual registration needed - automatic!
+```
+
+---
+
+### Use Case 6: Scene Cleanup
+
+**Problem:** Need to clean up scene-specific state before transitioning.
+
+**Solution:**
+```csharp
+public class ParticleSpawner : ManagedBehaviour
+{
+    private List<GameObject> _activeParticles = new List<GameObject>();
+
+    internal override void OnSceneUnloading()
+    {
+        // Clean up before scene unloads
+        foreach (var particle in _activeParticles)
+        {
+            if (particle != null)
+                Destroy(particle);
+        }
+        _activeParticles.Clear();
+    }
+}
+```
+
+---
+
+### Use Case 7: First-Time vs Restored State
+
+**Problem:** Need to play intro animation only on first visit, not when restoring from save.
+
+**Solution:**
+```csharp
+public class LevelIntro : ManagedBehaviour
+{
+    public override bool AutoRegisterForSave => true;
+    
+    private bool _hasPlayedIntro;
+
+    internal override string OnSceneSaveRequested()
+    {
+        return JsonUtility.ToJson(new { hasPlayed = _hasPlayedIntro });
+    }
+
+    internal override void OnSceneRestoreRequested(string data)
+    {
+        var save = JsonUtility.FromJson<SaveData>(data);
+        _hasPlayedIntro = save.hasPlayed;
+    }
+
+    internal override void OnSceneRestoreCompleted()
+    {
+        // This fires whether we restored or not
+        if (!_hasPlayedIntro)
+        {
+            PlayIntroAnimation();
+            _hasPlayedIntro = true;
+        }
+    }
+}
+```
+
+---
+
+
+## Common Patterns
+
+### Pattern: Manager Singleton
+```csharp
+public class MyManager : ManagedBehaviour
+{
+    private static MyManager _instance;
+    public static MyManager Instance => _instance;
+
+    internal override void OnManagedAwake()
+    {
+        _instance = this;
+    }
+}
+```
+
+### Pattern: Event Subscription
+```csharp
+internal override void OnManagedStart()
+{
+    EventBus.OnSomething += HandleEvent;
+}
+
+internal override void OnManagedDestroy()
+{
+    EventBus.OnSomething -= HandleEvent;
+}
+```
+
+### Pattern: Save/Restore
+```csharp
+public override bool AutoRegisterForSave => true;
+
+internal override string OnSceneSaveRequested()
+{
+    return JsonUtility.ToJson(myData);
+}
+
+internal override void OnSceneRestoreRequested(string data)
+{
+    myData = JsonUtility.FromJson<MyData>(data);
+}
+```
+
+### Pattern: Custom SaveId
+```csharp
+// For singletons or special cases
+public override string SaveId => "PlayerInventory";
+
+// For scene-specific instances
+public override string SaveId => $"{gameObject.scene.name}/MySpecialObject";
+```
+
+## Troubleshooting
+
+### "NullReferenceException when accessing Manager.Instance"
+**Problem:** Accessing singleton in `OnManagedAwake()`  
+**Solution:** Move to `OnManagedStart()` where managers are guaranteed ready
+
+### "My SaveId is colliding with another component"
+**Problem:** Two components have same GameObject name and type  
+**Solution:** Override `SaveId` property with unique value
+
+### "My component isn't receiving lifecycle callbacks"
+**Problem:** Not inheriting from `ManagedBehaviour`  
+**Solution:** Ensure class inherits `ManagedBehaviour` (not plain `MonoBehaviour`)
+
+### "Save data isn't persisting"
+**Problem:** `AutoRegisterForSave` is false  
+**Solution:** Set `public override bool AutoRegisterForSave => true;`
+
+### "OnSceneRestoreCompleted isn't firing"
+**Problem:** Missing implementation  
+**Solution:** Override the method even if just logging for now
