`wan/modules/action_module.py` and `wan/modules/causal_model.py` additionally
carry the action-conditioning and block-causal attention changes introduced by
Matrix-Game 2.0 (https://github.com/SkyworkAI/Matrix-Game).

model/, pipeline/, trainer/  --  Self-Forcing and Causal Forcing
--------------------------------------------------------------------------------

The training and inference scaffolding under `model/`, `pipeline/` and `trainer/`
is derived from Self-Forcing (https://github.com/guandeh17/Self-Forcing) and
Causal Forcing (https://github.com/thu-ml/Causal-Forcing), both Apache-2.0, which
in turn build on CausVid (https://github.com/tianweiy/CausVid). The ForgeWM
additions are the four-stage schedule, the action-conditioned data path, the
first-chunk denoising schedule (FFE), and the CrossFPS action-interface widening.

Weights and data -- NOT covered by this repository's licence
--------------------------------------------------------------------------------

* Matrix-Game 2.0 base weights, fetched by `scripts/download_models.sh` from
  https://huggingface.co/Skywork/Matrix-Game-2.0, are distributed by Skywork AI
  under their own terms. ForgeWM's Apache-2.0 licence does not extend to them.

* GF-Minecraft gameplay videos and action labels come from GameFactory
  (https://github.com/KlingAIResearch/GameFactory) under that project's terms.
  `scripts/prepare_data.py` re-encodes them; it does not relicense them.

* The CrossFPS gameplay data comes from SCOPE (https://z2tong.github.io/SCOPE)
  and is not part of this repository. `configs/crossfps_*.yaml` describe the
  recipe; supplying the data is the user's responsibility.
