+
+## Core Architecture
+
+### 1. Event System
+```
+SpawnerEventType (Enum)
+├── Lifecycle Events (3)
+├── Stacking Events (3)
+├── GUI Events (3)
+├── Player Actions (3)
+├── Command Events (3)
+├── Admin Events (2)
+└── Other Events (7)
+```
+
+### 2. Logging Flow
+```
+Action Occurs → Event Triggered → SpawnerAuditListener OR Direct Logger Call
+                                            ↓
+                                   SpawnerLogEntry Created
+                                            ↓
+                                   Added to Queue (Async)
+                                            ↓
+                                   Batch Processing (2s interval)
+                                            ↓
+                                   Written to File
+                                            ↓
+                                   Rotation Check → Cleanup
+```
+
+### 3. Configuration Structure
+```yaml
+logging:
+  enabled: false|true
