While most imports use the columnMapping from the assigned ImportMappingProfile, occasionally a single batch requires a one-off adjustment — for example, if a lab changed its column order in one deliverable. The columnMapping on the ImportBatch records any such per-batch override applied at parse time, separate from the shared profile. This preserves the profile's original configuration for future imports while accurately documenting what mapping was actually used to produce the AnalyticalResults in this particular batch.

Import Batch Column Mapping
The `columnMapping` on an ImportBatch is a JSON field that can hold a per-batch column mapping override, supplementing or replacing the profile's mapping for this specific file.
