The PXRD crystal-system classification and lattice-prediction CSVs already cite their source databases but do not identify the individual structure records. Add `Entry ID`, `Source Database`, `Version Date`, and `Extraction Date` to all 60 rows in each CSV using the supplied provenance records.
The records identify Materials Project v2018.11 and CoRE-MOF 2019, with extraction date 2025-04-22. Existing `Reference` citations are retained.
Validation: all 120 rows map uniquely to their supplied provenance records. Row order and every value in every pre-existing column are unchanged, including PXRD peaks, intensities, Miller indices, crystal systems, and lattice parameters. Only the four provenance columns are appended.
