where do they collections declare that they are queryable?

That's because it isn't explicitly set (like it is for service
collections like Ampache), but rather determined on the fly in
CollectionManager::slotNewCollection( Amarok::Collection* newCollection )

Personally, I don't understand the MetaObject blackmagic it is doing..
but the key line is:
enumValue == -1 ? status = CollectionEnabled : status =
(CollectionStatus) enumValue;

For the SqlCollection enumValue always == -1, so it's status is set to
CollectionEnabled.

I don't there there exists a collection that ever makes it to the
latter half of that trinary operation, and I wouldn't know how to make
one. Ask Maxx!
