        Recorded source labels for instruction-following and coding records.
        Exact source releases and terms remain to be verified.

    Nemotron-Cascade-2-SFT-Data / math           (NVIDIA)
        CC-BY-4.0 was recorded. Source of the 160 records labeled
        nemotron-cascade2-math. The math slice was taken whole rather than
        sampled per record, so mapping to individual upstream records is not
        established. See data/README.md for the source-label inventory.

The sub_source field retains recorded attribution, not proof of complete
record-level provenance. See data/FIDELITY_AUDIT.md for the current status.
