 `src/joc_qmf.py` loads the QMF tables, while `src/joc_decode.py` loads the JOC Huffman trees. Python does not read C/C++ headers under `native/`.
 
 The corresponding native data are stored in `native/src/qmf_tables.h` and `native/src/joc_huffman_tables.h`. Changes on either side should update the other and be checked for value-by-value agreement.
