Telemetry Troubleshooting

Symptom	Likely Cause	Fix
Data shows in live view but not in logs	DataLog not started	Call DataLogManager.start()
Missing values	Unsupported type or not exposed	Ensure fields/getters are visible to annotations
Choppy live charts	Oversampling	Reduce publish rates or downsample in viewer
Big log files	No rotation	Move to USB and clean between events
