\begin{document}$ \sqrt{s}=5.02 $\end{document} TeV Pb+Pb collisions. Employing the improved SHELL model, which incorporates collisional and radiative energy loss, as well as medium response, we quantify distinct quenching signatures for quark and gluon jets. Key findings include: (1) Pure quark jets exhibit strong EEC enhancement at large angular scales, while gluon jets show a bimodal enhancement pattern at small and large scales; (2) Dual-shift decomposition in the EEC ratio reveals shifts toward large angles is primarily driven by energy loss, while small-\begin{document}${R_{{\rm{L}}}}$\end{document} shifts extend beyond selection bias and indicate intrinsic enhancement of the gluon-initiated jets; (3) Quark jets experience global suppression of averaged energy weight \begin{document}$ \langle{\rm{weight}}\rangle({R_{{\rm{L}}}}) $\end{document}, whereas gluon jets exhibit concentration toward small \begin{document}${R_{{\rm{L}}}}$\end{document}; (4) Mechanism decomposition identifies elastic energy loss concentrating \begin{document}$ \langle{\rm{weight}}\rangle({R_{{\rm{L}}}}) $\end{document} toward small \begin{document}${R_{{\rm{L}}}}$\end{document}, radiative loss dominating quark jet modification, and medium response amplifying large \begin{document}${R_{{\rm{L}}}}$\end{document} enhancement via soft hadrons. The observed flavor dependence in EEC modifications is dominantly driven by intrinsic jet structure differences rather than medium-induced mechanisms. We propose photon-tagged jets as quark proxies and inclusive charged-hadron jets as gluon proxies, demonstrating that they reproduce the respective flavor-specific quenching patterns. Our work establishes the EEC as a precision probe of color-charge-dependent jet-medium interactions, providing new constraints for the detailed \begin{document}$ \hat{q} $\end{document} extraction and QGP tomography, while highlighting the critical role of pre-quenching flavor asymmetries."> Study of the EEC discrimination power on quark and gluon jet quenching effects in heavy-ion collisions at<inline-formula><tex-math id="M1">\begin{document}${\sqrt{s}=}$\end{document}</tex-math></inline-formula> 5.02 TeV -
