(1) I presume I do NOT need to include any of the directives 

   % !TeX TS-program = pdflatexmk
   % !BIB TS-program = biber
   % !BIB program = biber

so long as I am using the pdflatexmk engine for typesetting.

(2) I think I’ve found the source of the problem — and the difference between the small test file and the actual project: In the actual project files, I have some as-yet dummy, defective, citations of the form 

      \textcite{WHAT}

that do generate warnings in the log. That’s what seems to cause all the bibliographies’ entries to be numbered 0. As soon as I remove those dummy citations, the numbering is normal.

I do find it odd that bibtex would mess up the actual bibliography numbering for that reason, rather than just not being able to properly typeset the \textcite’s in the body.

And when I switch back from option backend=biber to backend=bibtex for biblatex, and with those defective \textcite’s still present, I do NOT get the all-0s numbering error.

So biber is much fussier than bibtex!

(3) While digging around trying to pinpoint the source of the trouble, I noticed that the TeXShop pdflatexmk.engine I was using was an older version from 2017, and it includes the line

   "${LTMKBIN}"/latexmk -pdf -r "${LTMKEDIT}/latexmkrcedit" -e "\$TSUserCompileOptions=q/${2}/" -r "${TSBIN}/pdflatexmkrc" ${localrc} "$1”

whereas the current version of that engine has instead the line:

   "${LTMKBIN}"/latexmk -pdf -r "${LTMKEDIT}/latexmkrcedit" -e "\$TSUserCompileOptions='${2}'" -r "${TSBIN}/pdflatexmkrc" ${localrc} "$1"
  
What is the meaning of that change?
