I will summarize what is understood and proved beyond doubt in experiments regarding problems of the normal and superconducting state of cuprates by the proposal of loop-currents and associated quantum-critical fluctuations of the marginal Fermi-liquid form. I will follow up on this with a proposal of how to understand Fermi-arcs and magneto-oscillations in cuprates through topological decorations of loop-current order which has not yet been proven in experiments.
