    I created a flow which uses 3 `GenerateFlowFile` processors (named 
_Component A_, _Component A_, and _Component A (B)_) to evaluate the new 
filtering behavior. Each generates a flowfile with the content and _source_ 
attribute indicating the source (for the 2nd processor, the message & attribute 
refer to _Component A (2)_). I exercised the 
`SiteToSiteProvenanceReportingTask` with no accept/deny list, then only an 
accept value, then both. The functionality worked as expected; explicit deny 
overrode allow (see screenshot).
