In our workflow, we sometimes have someone do duplicate work for someone else, and we call the duplicate work the "shadow" job. This led to a need for a term for the original work in the database, so we started calling the original job the "original shadow", but this is rather awkward, and doesn't really make sense, since something that creates a shadow isn't a shadow, it's the real thing. Is there a word for something that casts a shadow, that pairs nicely with a shadow? For example, if someone sees a "parent" job in the system, they can guess that there will probably be a "child" job as well (unfortunately, we are already using the parent/child analogy for something else). "Caster" works, but it may put you in mind of spells or fishing instead of shadows.
