Changes in v2 include filtering, grouping and split isolation; assistant-reviewed intent descriptions and alias mapping; candidate sampling and paired target removal; restored available policy/context; and schema/metadata reformatting. Source utterances are retained. The MTOP/TOPv2 derived semantic data, including the adapted catalog, is distributed under CC BY-SA 4.0. Attribution does not imply upstream endorsement of this adaptation.

The frozen `default` and retained legacy replay include Google Research SGD (CC BY-SA 4.0), Amazon MASSIVE (CC BY 4.0), Glaive v2 and NousResearch Hermes (Apache 2.0 as recorded in the original card), attributed Nemotron records, NL2Bash (consult its source terms), Git natural-language commands (consult its source terms), and maintainer DevOps templates (Apache 2.0). Their original links and notices remain in the [archived legacy data card](docs/legacy-data-card.md). The v2 release does not claim to resolve unspecified legacy-source terms. The four original data files are unchanged from `a84ea0337a424e287dc6f36f6b9fa320fb920fb0`.

## v3 additions and modifications

The repaired semantic descriptions, conflict catalog and MTOP/TOPv2 examples retain CC BY-SA 4.0. Recovered Hermes requests, call sets and schemas retain the original NousResearch source terms; native Nemotron tool schemas retain the NVIDIA component terms listed above. Repairs include filtering, descriptor clarification, candidate regeneration, source recovery, additional group reservations and explicit supervision masks. These changes do not certify upstream outputs or imply author endorsement.

HINT3 v2 (Curekart and SOFMattress), by Haptik and Gaurav Arora, Chirag Jain, Manas Chaturvedi and Krupal Modi, is provided as a separate native auxiliary database. The database is under ODbL 1.0 and individual contents under DbCL 1.0. The adapted HINT3 view retains those terms. See the [verbatim original notice](licenses/HINT3-ODbL-DbCL.txt), [attribution and source links](licenses/HINT3-attribution.md), and [pinned file hashes](curation/v3/hint3_source_manifest.json). HINT3 labels are not silently relicensed as MIT or merged into the choice catalog.
