These are complete duplicates rather than near-duplicates — every column value matches perfectly within each pair.\n\nThe duplicates represent only 8 rows out of 7,851 total (0.1%), so the dataset is largely clean, but these 4 matches should be deduplicated to avoid double-counting in any match-level analysis." } ```
