• The formalism is essential for accurate QGP tomography.
• The energy loss expression is successfully integrated into the DREENA framework.
• The framework allows for constraining bulk QGP parameters by combining low-p and high-p theory with experimental data.
• The study provides new insights into the properties of QGP.
• The ability to account for arbitrary temperature evolution enhances the accuracy and applicability of the framework.

Key Insights
