The simply connected domino-tiling extension conjecture

A simply connected region is a domino-tileable region in the setting of the paper whose interior has no holes. Let the domino-tiling counting theorem of the paper be denoted by Theorem

$$. **Simply connected domino-tiling conjecture.** Theorem$$

holds for simply connected regions. The claim extends the paper's result from regions that may have holes to simply connected regions; the supplied text gives no resolution, so it remains open.
