So, is the Bathroom Project Finished Yet?

No.  No it is not.

On the good news front, it didn't require cutting away drywall to put in more backer board. The board that was there was large enough to provide support for the new sink.

However,

painting, which began over three weeks ago, is not yet finished.

New sink, new outline.  And yes, there is wall paper under all the layers of paint.

Sigh....
