I know, thanks.
Embedding involves changing the content of the EPUB file, which has nothing to do with the file name, contrary to what the OP seems to think. Even if the file name (not the embedded title) is changed to '123.epub', it would still have the same hash.
Therefore, 'Calibre truncates long names on Win10 with long paths enabled' is not related to the hash problem.
