I’m both asking how they should be named, and how to advertise them for programmatic consumption.
For example, and automatic testing program such as that included in quicklisp, should not try to stand-alone
load systems which are not designed to work stand-alone.   We have to work around this by artificially
making all systems “work” in standalone enough to fool quicklisp.

quickref is another tool which tries to publish documentation extracted from packages, but quickref would
like to skip packages which are not part of the public API, such as test case packages which may require
other non-public testing frameworks.

It would be nice if asdf had some declarative way of specifying which systems are intended as entry points.
That would also avoid different people relying on non-standard naming conventions to encode declarative 
information.

When creating an lisp application I usually have one (or several) what I call top-level asdf systems

What is the convention with asdf to distinguish entry-point systems from internal/private
systems?

I generally try to use either Faré's "slashy" systems (like "shop2/common") in my work. When I can, it's even better to use a :module which isn't visible at all.

I think what you are really asking is "how should I name a system that the user should never load directly?" I don't have a great answer to this question.
