ps: I just uploaded a fixed cfitest.epub with that missing content.opf id added back.
So hopefully, if the ACE Checker output puts out normal epubcfis and an error string, you should be able to collect the epubcfi, and error strings and run this through the cfi_convert for that epub and build up the needed validation results.
You may have to correct a few things to make it match exactly in Sigil as you have done in other validation plugins, but there should be enough info provided to fix up what you need (I hope).
Just let me know if I can help or answer any questions.
