Per-component record at pinned commits. Code: 4DGaussians (Apache text), Real-time 4DGS and DreamGaussian4D (MIT text), Consistent4D (Apache), Dynamic 3D Gaussians (MIT except Inria-licensed files) and SV4D inference code (MIT). Four repositories carry a conflict between the root licence and Inria non-commercial source headers or files (4DGaussians, Real-time 4DGS, DreamGaussian4D) or a stated split (Dynamic 3D Gaussians). Weights: SV4D 2.0 under the Stability AI Community License with a card that contradicts itself at exactly US $1,000,000 revenue; SV4D v1 card unreadable without login; Consistent4D and Dynamic 3D Gaussians advertise third-party or archive checkpoints without terms. Datasets: Neu3D is CC BY-NC 4.0; D-NeRF/HyperNeRF/Nerfies dataset terms are not stated in the READMEs read; DyCheck's iPhone dataset is Apache 2.0 per its README. No legal clearance is concluded.

Curator qualifications: All three same-repository conflicts verify: a root Apache-2.0 or MIT licence sits next to Inria non-commercial headers in source files. The SV4D 2.0 card's self-contradiction at exactly US $1,000,000 ('or more' needs an enterprise licence; 'or less' is free) verifies, and the licence text uses 'more than'. 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] No legal resolution of root-licence vs Inria-header conflicts.

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