i have a curve that is deforming and the topology is changing. So i cant use rest attribute

if i use a noise function it is point dependent and so gradually the curveu noise changes on my curve.

How can i add a noise to the curveu attribute independent of the points?

I want it to be static, somehow based on the curveu attribute so that it sticks on my curve no matter the deformation.

I can do this manually with a ramp parameter of course but i want it to be procedural with a seed value.

Essentially i want to do exactly what the ramp parameter does - remapping the curveu attribute - but using a noise

Any tips?

You need to find the way to not change topology. Without it will be hard to make procedural setup

i solved the problem using the attribute noise SOP to break up the original curveu attribute.
