That was not the offer.  The offer was to show you how to implement a
discrete eev command using another framework, possibly simplifying its
implementation.  Hopefully, from seeing the code used to do this, you could
dig in yourself and follow the flow to whatever level you like.  Hyperbole,
for example, has been implemented across years of part-time work.  Of
course, it has complexities in its implementation and if the non-abstract
parts of that interest you, then use edebug or trace commands to explore
the code flow but I wouldn't expect anyone to write that out for you.

#3 is closer to the offer.  If you want to see a Hyperbole function or
button type equivalent, I can show you that, i.e. you load Hyperbole and
then you use Hyperbole or eev syntax to jump to a point in a video that is
done through a Hyperbole implementation.  But I can't explain the Hyperbole
dispatching mechanisms except at a high level.  hkey-alist in Hyperbole is
not hard to understand.  The prioritized list of implicit buttons types in
Hyperbole is not that hard to understand.  That kind of level I can discuss.
