Copy Processor

Overview

The Copy Processor (copy) duplicates one or more files from specified source paths to target paths without modification.
Useful for routing intermediate files, renaming outputs, or propagating cached artifacts.

Note that arbitrary inputs require matching outputs. The example uses "subject" and "metadata" but any names will do.
