the from kfx log says theyre pdf. using mutool (tested with both artbox and cropbox) on the pdf doesnt leave that pixel edge. looking at the pdf, there seems to be a tiny sub pixel (<1/10th maybe) line

The KFX Input plugin uses calibre's built-in "page_images" PDF to JPEG conversion routine which in turn uses pdftoppm included with calibre.
I have looked at several books available to me in KFX format that use PDF as the internal image format. So far I have not seen the problem you describe in the JPEG files produced when converting those to EPUB using From KFX.
In order to research this further I would need access to a book that exhibits the problem. Posting copyrighted material is not allowed here on MobileRead but if you PM me a link to somewhere I can download one the those KFX files I will look into it.
