sector of the QCD phase diagram, beyond the boundaries [@Rischke:2003mt] of Fig.2b.

The critical $D+Au$ control experiments in 2003 could have found that the $Au+Au$ QGP observables were strongly distorted by the possible initial CGC state that created it. This would have certainly foiled Eq.(1). The search for the bulk QGP phase of matter would then have had to await higher energies and densities at LHC or for a better understanding of how to deconvolute that initial state physics. The large positive signatures in similar $p+Pb$ control experiments at SPS showed in fact initial effects strongly distort key observables. At SPS the physics of high $p_T$ Cronin enhancement and $p+A\rightarrow J/\psi$ suppression remain the important open problems. In contrast, at RHIC energies, the absence of jet quenching at midrapidity and the “return of the jeti” correlations in ${\bf dA=D+Au}$ provided the check-mate completion of Eq.(1).

As emphasized by McLerran[@McLerran:2004fg] in these proceedings, the $D+Au$ control at RHIC at high rapidities does in fact produce a positive signature for new initial state physics. In those kinematic ranges $x_{BJ}<0.001$, ${\rm  {\bf dA}}$ fails as a null control for QGP, but may signal the onset of nonlinear CGC initial conditions. In this lecture,
