Supplementary Data 1 — complete executable archive

This ZIP contains the complete data tree in lossless TAR.XZ form to reduce
the transfer size. No numerical precision or scientific output is removed.

1. Extract this ZIP into an empty folder.
2. Run: python extract_data.py
   This uses only the Python 3 standard library, makes separate writable
   copies of duplicate files and refuses to overwrite an existing data tree.
   Alternatively, extract Giza_Supplementary_Data_1.tar.xz with a TAR.XZ-capable utility,
   then run the included separate_duplicate_files.py before rewriting files.
3. Follow README.md inside Giza_Supplementary_Data_1 for numerical checks
   and full reproduction. SHA256SUMS.txt covers the extracted files.
