Does a 37 CFR 1.130(b) declaration need to demonstrate that the disclosure was enabling?

No, a 37 CFR 1.130(b) declaration does not need to demonstrate that the disclosure was enabling under 35 U.S.C. 112(a). The MPEP explicitly states:

There is no requirement that the affidavit or declaration demonstrate that the disclosure by the inventor, a joint inventor, or another who obtained the subject matter disclosed directly or indirectly from an inventor or a joint inventor was an enabling disclosure of the subject matter within the meaning of 35 U.S.C. 112(a).

This means that the declaration only needs to show that the subject matter was publicly disclosed, not that it was disclosed in a way that would enable a person skilled in the art to make and use the invention.
