IEEE Citations in Markdown With Pandoc and CSL
Tested 2026-10-27 with Pandoc 3.13 on macOS x86_64.
Extract all files into one folder, open a terminal in that folder, then run:

pandoc paper.md --citeproc --standalone --output paper.html
pandoc paper.md --citeproc --output paper.docx
pandoc reordered.md --citeproc --standalone --output reordered.html
pandoc reordered.md --citeproc --output reordered.docx

paper.md: MapReduce [1], Parliament [2], MapReduce [1].
reordered.md: Parliament [1], MapReduce [2], MapReduce [2].
Both output formats have two references. All four builds returned 0 with no warnings.
Missing-key check [@missing2026]: warning, exit 0, unresolved citation.
Without --citeproc: keys remain visible, no formatted bibliography.
DOCX files are generated outputs; edit Markdown/BibTeX and regenerate.
