Stores tracks/track_0/data/raw_data with shuffle + gzip (level 4) instead of Blosc in the four data/Fundamental/ files that the Hub's ClamAV scan marks unsafe (Win.Exploit.CVE_2016_4332_1-6028013-0):

• 126987_3_Focused_Uncoded_TX.hdf5
• 559277_2_Focused_Uncoded_TX.hdf5
• 729304_2_Focused_Uncoded_TX.hdf5
• 829312_1_Focused_Uncoded_TX.hdf5

The matching bytes sit inside Blosc-compressed raw_data chunks, not in the HDF5 object headers the CVE is about, so this is a false positive (reported to ClamAV). Re-encoding with Blosc at another level or shuffle mode only clears some files (#82). gzip changes the chunk bytes completely and is the same fix as #83 for UBC session_01_f0374.hdf5.

Files changed: 4. Only the compression filter of raw_data changed. Its values, dtype, shape, chunk shape and fill value, every other dataset (still Blosc) and every attribute are untouched. The Sept 26 subject-ID fix (#74) is kept, since the files were rewritten from current main.

Checks, each file against current main (source SHA-256 matched the Hub):

• All 24 datasets compared byte-for-byte after decompression, including all 32 raw_data frames; all 53 attributes compared by name, order, dtype and value; dtype, shape, maxshape, chunks and fill value compared for every dataset. 0 differences.
• zea 0.1.7: File.validate() succeeds, and scan, metadata, load_parameters() and a full raw_data read run with no warnings (same as the originals).
• ClamAV 1.4.3, daily 28140 (--allmatch --max-filesize=1900M --max-scansize=2000M --max-scantime=0 --alert-exceeds-max=yes): all four originals are flagged, all four replacements are clean.

Diff (h5_diff against main: file hashes differ, no structure, dtype, shape, attribute or metadata change):

vanderbilt/data/Fundamental/126987_3_Focused_Uncoded_TX.hdf5: differs (main)

Hugging Face's own scan of the new files should be checked before merging.
