4dgs-Native

Per user direction frontier 4DGS-native — pivot к CAP4D (CVPR 2025 Oral, Toronto/Vector). Spec говорил «bypasses BFM» — true, но requires FLAME 2023 (Max Planck gated, same class). pytorch3d + chumpy + xformers + gsplat compiled на Blackwell sm_120 (productive). MMDM weights 3.6 ГБ downloaded. Smoke test fails на FLAME load step. Owner action: registration на flame.is.tue.mpg.de. Multi-day work after unblock.

После user catch (HVA = 2D drift, нужен 4DGS-native) — пивот к TalkingGaussian (ECCV 2024). Repo cloned, isolated venv-talking-gaussian, 3 CUDA modules скомпилированы на Blackwell sm_120 (diff-gaussian-rasterization, simple-knn, gridencoder через 3 patches). Blocker: Basel Face Model 2009 (BFM) gated на faces.dmi.unibas.ch — requires manual registration, не automatable. Plus dep stack нужен: OpenFace AU C++, EasyPortrait + mmcv-full==1.7.1 (Py3.12 incompatible), DeepSpeech TF1, training video 1-5 min (наша 16 sec). Honest report — cleanup path forward или откат к v7.
