Still not reading this thread carefully, but I
still have the impression that, for what you want
to do, you can use _advice_.
https://www.gnu.org/software/emacs/manual/html_node/elisp/Advising-Functions.html
When a function gets called you can do anything,
including introspect the current context,
reporting on it, and reinvoking the called arg
(with the same or different args). Pretty much
anything.
The only limitation of this approach is that,
like `debug-on-entry', it only takes control
when the function is actually invoked. Other
than that consideration, you can do pretty
much anything, with the full call context at
hand.
