  We report results of a comprehensive global $\chi^2$ analysis of nuclear
collision data from RHIC (0.2 ATeV), LHC1 (2.76 ATeV), and recent LHC2 (5.02
ATeV) energies using the updated CUJET framework. The framework consistently
combines viscous hydrodynamic fields predicted by VISHNU2+1 (validated with
soft $p_T<2$~GeV bulk observables) and the DGLV theory of jet elastic and
inelastic energy loss generalized to QGP fluids with an sQGMP color structure,
including effective semi-QGP color electric quark and gluon as well as emergent
color magnetic monopole degrees of freedom constrained by lattice QCD data. We
vary the two control parameters of the model (the maximum value of the running
QCD coupling, $\alpha_c$, and the ratio $c_m$ of color magnetic to electric
screening scales) and calculate the global $\chi^2(\alpha_c,c_m)$ compared with
available jet fragment observables ($R_{AA}, v_2$). A global $\chi^2<2$ minimum
is found with $\alpha_c \approx 0.9\pm 0.1$ and $c_m\approx 0.25\pm 0.03$.
Using CIBJET, the event-by-event (ebe) generalization of the CUJET framework,
we show that ebe fluctuations in the initial conditions do not significantly
alter our conclusions (except for $v_3$). An important theoretical advantage of
the CUJET and CIBJET frameworks is not only its global $\chi^2$ consistency
with jet fragment observables at RHIC and LHC and with non-perturbative lattice
QCD data, but also its internal consistency of the constrained jet transport
coefficient, $\hat{q}(E,T)/T^3$, with the near-perfect fluid viscosity to
entropy ratio ($\eta/s \sim T^3/\hat{q}\sim 0.1-0.2$) property of QCD fluids
near $T_c$ needed to account for the low $p_T<2$ GeV flow observables.
Predictions for future tests at LHC with 5.44 ATeV Xe + Xe and 5.02 ATeV Pb +
Pb are also presented.
