Incomplete mesh

The render mesh doesn’t reach the edges.
_RebuildEdges doesn’t help.

What is wrong with the surface (or with the mesher)?

The trim border is messed up. If you untrim the surface, and use the curves already in the file to re-trim it, it looks better.

I don’t know how the original trim border got that way, but it’s bad.

Ah ok, strange it is…
Thanks for the hint Mitch.
