I have finally found one case where a PDOC is always produced in the output MOBI ebook from Calibre. If the original is a MOBI, and it has cdetype set to PDOC then the output from Calibre will still have the PDOC. In this case, a MOBI to MOBI conversion will remove the PDOC from Calibre's internal version and any subsequent MOBI Sent to device or to disk will then have EBOK (assuming the "Personal doc tag" isn't present).
