A smooth zeroth-order potential does not obstruct the local bootstrap. Only the principal and first-order perturbations need to be small.

    Source documentation

    The potential times u has the needed order from the outer cutoff; it is not required to be smooth before the bootstrap.

    Local H1 and a smooth potential-source remainder give every Sobolev order on each smaller compactly supported localization.
