+## Normalized affiliations
+
+The `normalized` split uses `comet-datacite-ascii-v1`: Unicode text is
+transliterated to ASCII, lowercased, stripped of punctuation while preserving
+internal whitespace, and trimmed. Empty results are excluded. Its columns are
+`normalized_affiliation` (string), `total_occurrence_count` (uint64),
+`raw_affiliation_count` (uint64), and `doi_count` (uint64), plus explicit ROR
+coverage and deterministic ROR support lists. DOI counts are calculated from
+the DOI-affiliation attribution sidecar after normalization, so one DOI shared
+by multiple exact variants is counted once for the normalized key. Compact
+per-prefix attribution rows are published under
+`artifacts/normalized-prefix-attribution-*.parquet`.
