I did some more testing and that one notebook sample you provided (95E4A4423B184AE1B3DCF747F659B0CD!!PDOC!!notebook) breaks all of those rules. Do you have any idea what might be different about that notebook as compared with all of the other notebooks you have shared so far?
I do have an idea.

The document in this case started life as a PDF containing 8 Sudoku puzzles. I generally 'permanently delete' these as soon as I have solved the puzzles. This removes it from cloud, as well as the KFX, .sdr folder, and (in this case) the associated .notebook folder.

The fact that this folder had been orphaned suggests that it was deleted on my other Scribe. This was probably while I was doing experiments to see how sync of pen annotations worked in various scenarios.

So this document may have been one that I annotated with both Scribes. It may be some situation due to sync sequencing. I remember one case (but maybe not this one) where I had two solutions overlaid, for example.

Or it might be a simpler matter of having done a Delete Page operation along the way, and having things in undo buffer when document was closed?

At any rate, these are some scenarios that might factor in here (I'll try the Delete Page one to see what results)

Note that Permanently Delete does not remove personal documents from all devices, just from the one that initiated it, and from cloud storage. So you need to also Delete from the other device(s). It still seems like this should not orphan anything however.

(A few weeks ago I wrote a Python script to clean up orphaned .sdr folders, empty folders, and content specific temp files. At the time I had not observed any of these in .notebook folder so it does not look for any. Clearly I need to update it now...)
