We address instabilities of AdS flux vacua arising from string theory with string-scale supersymmetry breaking. The semiclassical regime, sourced by branes, eventually decays in a chain of tunneling processes, and we study the resulting final state using holography. We connect this setting with a number of swampland conditions, most prominently the emergent string proposal: D1-brane final states lie at infinite distance in the space of vacua, according to the quantum information metric. The resulting state has a number of features in common with an expected dual heterotic string: N=(0,1) worldsheet superymmetry is restored in a free sector due to Spin(8) triality free sector, while in the limit the anomalous dimensions of scalar vertex operators and single-trace higher-spin currents vanish in a peculiar exponential fashion as predicted by the distance conjecture and its CFT variant.
