Decide which source owns each field — and see every change

For every connection that brings data into Catalog, you now decide who owns each group of fields, with exceptions down to a single field or language: the source keeps it updated, Nucleo keeps it, or the source sets the first value and Nucleo takes over from there. Nothing is preset — the rules are yours.

Connecting a source never overwrites your work: differences are listed for you to resolve, and so are later updates that clash with a field Nucleo owns. An empty value from a source never wipes yours, and fields the catalog doesn't know yet stay visible until someone decides what to do with them. Every product also keeps a full change history — who changed what, when and from which source — with restore.
