March 2025: Robust Spectrum Data Ingestion - Implemented a critical robustness fix for spectrum data handling in xpsi-group/xpsi. When COUNTS data is missing, the system now falls back to using RATE data and sets exposure to 1.0, increasing reliability across varied spectrum data formats. This improvement reduces data processing errors and strengthens downstream analytics.
