so bibtex is being invoked properly.

latex defines \bibstyle.

\bibstyle is the command put into the .aux file, by
\bibliographystyle, to tell bibtex what style to use.  it's set up as
a no-op (equivalent to \newcommand\bibstyle[1]{}) so that when _latex_
reads the .aux file it doesn't bother with it.  similarly \citation
(put there by \cite).

i don't know.  programming it to process the document with latex makes
sense, though your key programming seems to imply not even that should
happen.  i can't help here :-(
