Phil, There should be a FORK event generated by a processor that generates multiple flow files from an incoming one. If a flow file is an exact copy of an incoming one, I believe it will have a CLONE event associated with it. Also, I think the session may handle this for you in the general case, although there are other processors like UnpackContent and QueryRecord that explicitly call ProvenanceReporter.fork().
