I want to generate KF8 without going through the conversion process (My Content --> Epub/Html --> KindleGen/Calibre/Other tool), as I need more control over kf8 file generation. The guidelines document & the format overview can't fulfill the need for specifications.
Are official KF8 file format specs available? Although I have found some information on links such as http://wiki.mobileread.com/wiki/KF8#The_Format, but want to avoid relying on unofficial/reverse-engineered stuff.
