The corrosion prediction CSV identifies the questions and labels but does not identify the underlying database. Add a Source column to all 60 rows with the citation for NACE International’s Corrosion Survey Database (COR•SUR) (2002) and its public Knovel link.
Validation: all 60 rows remain in their original order, and all values in the six existing columns are unchanged. Only source metadata is added; the model inputs and reference labels are unchanged.
