I generate two "adjacent" half-circles from two adjacent circles and a straight line using the Ctrl-Alt-/ procedure and deleting a top and a botton half.
I would like to make the remaining "wave" pattern a single object. I found two problems:
1 - The adjacency of the original circles doesn't seem to guarantee the perfect ovelap of the "adjacent" end points
2 - I did not find a way to really connect the end-points.
A side issue : as there is no node that could be snapped in the half circles, I was wandering if it was possible to convert them to a broken line without retracing it manually
3 small images : 1- the adjacent circles and the line, 2- the resulting half circles forming the wave pattern, 3- the gap between the supposedly adjacent points.
It seems to me that the stroke is drawn within the defining square. If there is adjacency it is at the outside corners of the line. If I wanted stroke continuity, I should make the circles closer by the stroke thickness. If the stroke was drawn "centered" on the defining square, perfect continuity could be achieved without any adjustment and independently of stroke thickness
Supposing that I make the suggested adjustment on the square positions and attain perfect visual continuity (I have done it and it works), remains the problem of defining the wave as a single object (grouping them is not the solution)
I have noticed another similar problem in the “cutting” operation. The line is defined passing by to the circle centers. I noticed that the height of the left half circle is more that half the hight of yhe circle, and less for the right part. It seems that there again stroke width plays a role
A stupid looking question : is it possible to have a fantom object? With a stroke width of 0?
Thank you for your impressive demo. It looks so simple after discovering how to use some options. One question remains if the ends are perfectly joined, each half circle remains an independent object; changes canot be made to them as a group (if several objects are selected, the Fill and stroke option is not available, same with a group of objects).The joining does not "close" space; two half-circles as those created in the earlier steps could be properly joined to look like a circle but cannot be filled.
Sorry if I ask so many questions but I am trying to find the potentials of Inkscape; as I have an old experience mainly in geographie, I have developped a taste for precision in position, dimension and "continuity" of objects. I have some difficulties finding those features in Inkscape but it will not prevent me to find it useful in the work I am doing these last years.
In my example above it´s a continuous path - but I´m not sure what you expect from a fill as it can just go from first to last point in a straight manner. If you want kind of a shape perhaps - then you have to add more nodes to do so like so for instance:

Can you make a screenshot of what you have so far - maybe with some annotation? I don't get the picture right now other than this:

You´re making this simple thing way too complex. It´s all about snapping:

No doubt that they can be filled, one at the time. See my beautiful eggs
i can also reconstruct a circle
but it cannot fool anyone, See the incomplete diameter
How fascinating all that!

So many possibilities:
