description	Diagnoses Dimension UI crashes, hangs, and unexpected runtime behavior. Use this skill when the application crashes on startup, charts don't render, data doesn't load, or analysis features fail.

Runtime Diagnosis

Evidence Collection

1. Check Java version: java -version (must be 25+)
2. Verify Maven build: mvn clean compile
3. Check LaF parameter: -DLaF=dark|light|default
4. Review logs for EventBus errors
5. Verify Dimension-DI, Dimension-DB, and Dimension-TT installed

Decision Matrix

Symptom	First Check
Crash on startup	Java version + dependencies installed
Chart rendering issues	JFreeChart-FSE module + LaF theme
Data not loading	JDBC/HTTP connection configuration
Analysis not working	Matrix Profile/ARIMA algorithms loaded
