Normalize Labels Gradually
One company says Total Revenue, another says Gross Revenue, a third says Top Line. One reports monthly, another quarterly, another H1/H2, another only annually. Collection never touches any of it. Normalization is a later, corpus-level act — a cluster of labels that mean the same thing, one chosen default, and an alias map — built by a person from real analysis across real portfolios, never by an agent guessing from what the words sound like.
