Genuine multipartite entanglement reached its theoretical limit of 1/2 in a two-walker quantum walk, irrespective of initial conditions or coin operator used. This unexpected insensitivity suggests a new level of control over entanglement generation, previously unseen in similar systems. Open boundaries appear key to this reliable production of quantum correlations for potential use in computation and simulation.
