+### Why the `app/` folder structure?
+
+Blueprint's `requests.app` field merges the contents of your `app/` folder directly into Pterodactyl's `app/` directory. This means:
+
+1. **PSR-4 Autoloading:** Your classes are automatically found by Laravel's autoloader
+2. **Correct Namespaces:** Use `Pterodactyl\Http\Controllers` (not custom Blueprint namespaces)
+3. **Case Sensitivity:** Linux requires exact folder casing — `Controllers/` not `controllers/`
+
+This architecture was validated through painful debugging and Gemini AI consultation.
