Membership provenance: historical RS is calculated from prices as they existed on each date, but the cross-sectional membership uses the current OmmAlpha NIFTY 500 survivor universe. The exporter labels these rows BACKFILLED_CURRENT_NIFTY500 rather than pretending historical constituent membership is exact.
