The same reader, keeping the merge's delivery provenance: value is the
merged payload parseJson returns, and delivery names, for every merged
element of a chunked array, the document that first delivered it (the merge's

by (#960). A streamed answer's chunk boundaries are that provenance alone;
the documents themselves are not carried.
