Completion conjecture for 3-free sets

A finite set of nonnegative integers is 3-free if it contains no three-term arithmetic progression. A completion of a 3-free set AA is a larger 3-free set AA' containing AA such that the Stanley sequence S(A)S(A') is regular.

Completion conjecture. Every 3-free set has a completion.

The paper presents this as a small result toward Rolnick's Conjecture 5.1; no resolution is supplied in the given text.
