Subsets marked "hosted with permission from the authors" carry no upstream license tag; their owners agreed to Meddies hosting via direct contact (2026-07-02). Every other subset is redistributed under the public license shown. The fw2_* configs come from orionweller/contrastive-pretraining, a personal artifact by Orion Weller (LightOn-adjacent, NOT a LightOn release), under ODC-By. Downstream training releases must preserve each subset's attribution and license obligations.

Provenance

metadata/source_manifest.parquet records, per subset: hf_id, requested source_revision, resolved source_commit_sha, license_id, license_status, row_count, and caveats. Rows are not marked training-ready by construction; license and quality review gate promotion.

Build

Generated on Modal (CPU-only). Sources were streamed and transformed through the tested datasets.external importers; large uploads are batched per config.
