  We explicitly construct N=4 worldline supersymmetric minimal off-shell
actions for five options of 1/2 partial spontaneous breaking of $N=8, d=1$
Poincar\'e supersymmetry. We demonstrate that the action for the N=4 Goldstone
supermultiplet with four fermions and four auxiliary components is a universal
one. The remaining actions for the Goldstone supermultiplets with physical
bosons are obtained from the universal one by off-shell duality
transformations.
