Two matched Qwen3-14B continued-midtraining datasets. Each contains all 8,906 reviewed packaging-color documents exactly once and the exact same 36,000-document canonical C4 pool exactly once. Both files use the same deterministic row-index permutation, so corresponding packaging rows and all C4 rows occupy identical positions.
No synthetic prefix is added and every row declares an empty mask_prefix; all document and EOS tokens remain… See the full description on the dataset page:
