Refined the Hostname generator output. This is a consistency breaking change.

v1647
February 12, 2026

A new environment setting, TONIC_LLM_ENABLE_ENHANCED_RECOMMENDATIONS_SAMPLE_DATA, determines whether LLM-based sensitivity scans include sample data. Using sample data improves the quality of the detections. When set to false, only schema information is sent. The default value is true.
