This talk follows one narrative from collapse to repair in directed, multilayer networks. In interdependent systems we show how direction reshapes tipping behaviour, producing rich phase structure and abrupt failures under targeted perturbations; the same lens yields minimally invasive interventions for fastest dismantling and, by inversion, principles for hardening. A dynamical model then captures spontaneous recovery, hysteresis and finite-size state switching, delineating when recovery is feasible and at what cost. We translate the framework to data-rich domains: in human molecular networks, coupling gene regulation, protein interactions and metabolism explains disproportionate gene influence and how multilayer wiring governs robustness and lethality. We close with a brief extension to mutualistic ecosystems, where interaction structure can trigger extinction cascades and, counter-intuitively, easing competitive pressure can aid biodiversity. Together these results offer a unified map of critical transitions and actionable levers for control and recovery, and invite collaboration on open mathematical and data-driven questions.
