Query for specefic edges that are looped around faces?

Hello, still having difficulty with featurescript! I am trying to query these edges from a loop of faces:
I have already got the faces, but when I use qEdgeAdjacent(), it selects the end edges as well. I don't need these as I am hoping to use the edges as arguments for a fillet operation. How could I query this?
I have tried using a for loop to check if the edges are a specific length, but I have no way of storing them in a variable.
All help greatly appreciated.
Thanks

One way to do this query is to say "I want all edges such that all of their adjacent faces are in the given faceSet". The way to phrase it for FS is more complicated, unfortunately "Take all edge-adjacent edges for the given faceSet and subtract from them all edges that are edge-adjacent to faces edge-adjacent to the given faceSet but not in faceSet"
As code, it'll look something like (untested):const adjacentFaces = qSubtraction(qEdgeAdjacent(faceSet, EntityType.FACE), faceSet);<br>const adjacentEdges = qEdgeAdjacent(faceSet, EntityType.EDGE);<br>const containedEdges = qSubtraction(adjacentEdges, qEdgeAdjacent(adjacentFaces, EntityType.EDGE));
