We formulate the universality of regular precursor rupture fronts in functional network parameter space, in light of recent analysis of acoustics emissions-coupled friction experimental results. Furthermore, using a phenomenological approach based on friction networks, we propose that the energy of the ruptures can be extended in terms of networks motifs and the transition from regular rupture to slow deformation can have a third production from the critical rupture class, comparable with the direct observations of this phenomena in the transparent samples . Based on this model, the transition from slow ruptures (i.e., creep pulse) to the critical speeds of ruptures is possible. In addition, the evolution of arrested rupture fronts is inspected through a statistical-network modelling which sheds light on the communities evolution. We propose a phase diagram for the friction networks which depends on the scaling coefficients of scalar parameters and can show a transition towards the capturing of the links by a single node, i.e., gel-like friction networks.
