There is an internals guide in the apt source code, but it isn't going to be
what you want. The best documentation is example code, and there is plenty
of that around. The pipeline data is really pretty much self-explanatory;
add a hook pointing to /bin/cat and watch it for a while.
But, I don't see why you should need to hook into apt at all in order to do
what you want. If the files you change are conffiles, your changes should
be preserved, and if they aren't conffiles, you can divert them.
