What terms govern the non-text guardrail parts shipped in the Cosmos-Transfer1-7B snapshot: SigLIP so400m, the Resnet50_Final.pth face-blur model, NVIDIA's safety_filter.pt and blocklists, and nltk_data (wordnet, punkt_tab)?

SigLIP carries an Apache-2.0 declaration in its card header (no licence file in the repo). The face-blur file Resnet50_Final.pth shares its name with a weights file that the upstream Pytorch_Retinaface project distributes (that repository is MIT-licensed; NVIDIA code cites it, but the origin of the bundled bytes is not verified); neither that licence nor its README states terms for the weights or the WIDERFACE training data, and the bundle file was not compared to upstream. NLTK data is governed per package: wordnet carries a Princeton permission notice, while punkt_tab is listed by the NLTK maintainers as an unclarified licence. NVIDIA's own safety_filter.pt and blocklist files fall under the NVIDIA Open Model License metadata of Cosmos-Guardrail1 (card unreadable). NVIDIA's ATTRIBUTIONS.md lists neither the SigLIP weights, the face-blur weights nor the NLTK data. Curator qualifications: SigLIP (apache-2.0 header metadata), the RetinaFace repository MIT licence, the NLTK per-package regime (wordnet permission notice; punkt_tab no licence attribute, unclarified) and the safety_filter weights_only load all verify. The finding that weight provenance for Resnet50_Final.pth is unverified (name match only) is correctly bounded. Summary says ATTRIBUTIONS.md lists neither the SigLIP weights, the face-blur weights nor the NLTK data. More precisely, ATTRIBUTIONS.md does list 'Pytorch_Retinaface - MIT License' (the code project the face-blur model comes from) and 'Nltk - Apache License 2.0' (the library). It lists no weights or data package and has no SigLIP entry. The point stands for weights and data, but the code projects are attributed. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.

Evidence claims

[sourced_fact] SigLIP carries an Apache-2.0 declaration in its card header (no licence file in the repo). The face-blur file Resnet50_Final.pth shares its name with a weights file that the upstream Pytorch_Retinaface project distributes (that repository is MIT-licensed; NVIDIA code cites it, but the origin of the bundled bytes is not verified); neither that licence nor its README states terms for the weights or the WIDERFACE training data, and the bundle file was not compared to upstream. NLTK data is governed per package: wordnet carries a Princeton permission notice, while punkt_tab is listed by the NLTK maintainers as an unclarified licence. NVIDIA's own safety_filter.pt and blocklist files fall under the NVIDIA Open Model License metadata of Cosmos-Guardrail1 (card unreadable). NVIDIA's ATTRIBUTIONS.md lists neither the SigLIP weights, the face-blur weights nor the NLTK data. · locator: producer work copy work/hf-api-google_siglip-so400m-patch14-384.json; producer work copy work/retinaface-LICENSE.MIT; producer work copy work/gh-cosmos_transfer1_auxiliary_guardrail_face_blur_filter_face_blur_filter.py; producer work copy work/gh-cosmos_transfer1_auxiliary_guardrail_video_content_safety_filter_video_content_safety_filter.py; producer work copy work/nltkdata-LICENSE-OVERVIEW.md; producer work copy work/nltkdata-DATASET-LICENSES.md; producer work copy work/nltkdata-wordnet.xml; pr source
