Added composite_figi identifiers to 13,004 rows (1,539 unique ISINs) previously missing this field, increasing coverage from 7,235 to 8,774 unique ISINs with composite_figi (from 80.7% to 97.9%). Methodology: - Extracted all unique ISINs lacking a composite_figi from equities.csv - Queried the OpenFIGI API (https://api.openfigi.com) using ISIN as the search key to obtain the corresponding composite FIGI identifiers - Mapped results back to all rows sharing the same ISIN Impact: - Only the composite_figi column was modified - No existing composite_figi values were overwritten or removed - No other columns were altered - Row count and order are unchanged (159,914 rows)
