Geometry Nodes: Bend each instance to curve
As quellenform pointed, you cannot bend instances. Instance is an object inside object, so in order to get points information you have to realize instances, so that they will be converted into meshes ...

Ripping vertices with more than two connected edges
I know, no one asked, but what if some vertices were already split and you wanted to keep it this way? You can do so by capturing the indices before splitting (so after splitting the new vertices ...

Fill corners with faces on an adaptable mesh tool with geometry nodes
As already written in the other answer:
There is hardly any useful way to get a satisfactory result only from vertical edges, so it is easier to process the horizontal edges.
That's why I'm using a ...
