When a generated structure goes stale, what regenerating changes, and THE MAPPING THAT QUIETLY LOSES A FIELD WHEN YOU DO. Module 4 established that the adapter GENERATES a structure at design time and that the generated copy is a snapshot. The source can change underneath it — a Fusion update adds fields, renames one, changes a type — and your integration goes on using the old shape until something breaks. REGENERATING REFRESHES THAT SNAPSHOT, AND THAT IS THE MOMENT OF RISK RATHER THAN THE FIX. The new structure replaces the old one, and the mapper reconciles what it can. Fields that still match keep their mappings. Fields that were renamed do not match anything, so THEIR MAPPINGS ARE DROPPED — silently, because from the mapper's point of view the target field simply no longer exists.
