 Notes:
 
-- MQTT broker host/port are currently hardcoded in Java (`MqttClientService`): `tcp://localhost:1883`.
-- Several Unreal-related paths are absolute and environment-specific.
+- Paths can be provided with or without wrapping quotes; startup sanitizes surrounding quotes.
+- Unreal-related defaults are environment-specific and should be replaced per machine.

 # Known Issues
 
-## 1. Hardcoded Environment Paths
+## 1. Environment-Specific Defaults
 
-Several runtime paths are absolute and machine-specific:
+Configuration is now path-driven, but several default values in `application.properties` are still machine-specific:
 
-- animation output file path in `AnimationFileService`
-- Unreal process script paths in `application.properties`
-- PID file cleanup paths in `ProcessManagerService`
+- Unreal startup script paths
+- Unreal/signalling PID file paths
 
 Impact:
 
-- project is not portable across machines without local path edits
+- configuration updates are required before first run on a different machine
 
 ## 2. Database Deleted on Shutdown
