Four items need curator attention: (1) TripoSG advertises MIT but its NOTICE lists code derived from Tencent HunyuanDiT (Tencent Hunyuan Community License notice) and the BRIA RMBG-1.4 background-remover whose card says non-commercial; the README downloads RMBG weights. (2) TRELLIS-500K metadata says MIT while the DATASET.md describes assets curated from Objaverse(XL), ABO, 3D-FUTURE, HSSD and Toys4k and states the dataset is CSV metadata; asset-level licences were not read. (3) Hunyuan3D repos ship .ckpt (pickle-capable) next to safetensors; 2.1 ships .ckpt and .bin; TripoSR ships model.ckpt; the licence texts do not address file formats. (4) The Tencent Hunyuan 2.0 HF card links its licence at LICENSE.txt while the HF file list shows LICENSE.

(4) The Tencent Hunyuan 2.0 HF card links its licence at LICENSE.txt while the HF file list shows LICENSE.

Curator qualifications: All four items reproduce from source text read in this pass (source_statement level; nothing executed or downloaded beyond text/API JSON). (1) TripoSG: LICENSE at fc5c4099 is MIT and the HF card front matter says license: mit, while NOTICE names FOUR upstream components: RMBG (Copyright BRIA AI, License: bria-rmbg-1.4), Diffusers (Apache 2.0), HunyuanDiT (Tencent Hunyuan Community License notice) and FlashVDM (Tencent Hunyuan FlashVDM Community License notice). NOTICE says the project includes code from RMBG, not only that the quick start downloads RMBG weights. The RMBG-1.4 card is itself inconsistent in wording: licence link to the BRIA agreement, a gated-access description of 'source-available ... non-commercial', and body text 'released under a Creative Commons license for non-commercial use'. (2) TRELLIS-500K: confirmed. The HF metadata says mit over 6 CSV configs; DATASET.md (8694 bytes) contains no licence or terms wording at all and directs users to download the underlying assets with dataset_toolkits/download.py from the five sources. (3) Weight formats: confirmed and sharpened. Hunyuan3D-2 offers safetensors twins for the DiT/VAE modules, but hunyuan3d-paint-v2-0/text_encoder and hunyuan3d-paint-v2-0-turbo/{text_encoder,vae} exist only as .bin. Hunyuan3D-2.1's shape DiT and VAE exist only as model.fp16.ckpt, and its paint text_encoder/unet/vae only as .bin (only image_encoder is safetensors), so the 'prefer safetensors where both exist' proposal does not cover 2.1's core modules. TripoSR ships only model.ckpt. TripoSG (3), TRELLIS-image-large (8) and SF3D (1) are safetensors-only. (4) Confirmed for 2.0: the card license_link targets blob/main/LICENSE.txt, and the file list at 9cd649ba holds LICENSE only. Hunyuan3D-2.1 instead links GitHub Tencent-Hunyuan/Hunyuan3D-2.1 blob/main/LICENSE, an unpinned cross-host link. Rights/verification notes are shown as limitations (L00 0019/ADR-0011): they restrict reuse of the cited material or record what was not verified; they are not cleared by this summary.

Limitations: [rights_conflict_record] Component rights remain unknown: no licence text for the Tencent Hunyuan Community agreements, the FlashVDM agreement or the BRIA agreement was read in this pass. A conflict between notices is not a determination of permitted use. [component_reuse_restriction] TRELLIS-500K asset-level licences (Objaverse-XL per-object, ABO, 3D-FUTURE, HSSD, Toys4k) were not read. The MIT label applies to the CSV metadata as HF metadata only.

Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
