@JSWolf, @DNSB: I promised to come back on splitting. epubsana will not split files, not even as an option. That is by design: epubsana only repairs defects that epubveri reports, and only when there is exactly one correct fix that keeps the content intact. A chapter over 260 KB is valid EPUB, because the limit belongs to some reading systems and not to the format. Where to cut is a decision about the book, as DNSB says, and a split has to rewrite every link, TOC entry and manifest item around the cut. That is a conversion, not a repair. calibre already does it on output, and Sigil's Split at Cursor and Split at Markers are the right tools when you want to choose the cut yourself.
DNSB, thank you for the library timings: 17,703 books in about three minutes on 14 cores.
