# Attribution and checkpoint scope

Phoenix-Pretrain distributes the Phoenix-MWA Robot37 Joint96 world-action
pretraining checkpoint at optimizer step 256013. It contains the video and
action experts and proprioception encoder, using 48 WanVAE channels and
48 CS-VAE channels. It is a weights-only initialization checkpoint, not a
full optimizer-state resume or a benchmark post-trained policy.

The video expert is derived from Wan2.2-TI2V-5B. The Wan Team's upstream model
is distributed under Apache License 2.0; a copy is included in
`LICENSES/Apache-2.0.txt`.
Upstream: https://huggingface.co/Wan-AI/Wan2.2-TI2V-5B .

Phoenix Encoder and CS-VAE weights and their notices are distributed separately
in OpenPhoenix/Phoenix-Encoders and AnyverseDynamics/Phoenix-Encoders.
WanVAE, text/tokenizer components and training datasets are obtained separately
under their respective terms.

The public checkpoint uses Phoenix/CS-VAE identifiers and omits private local
paths. Those metadata changes preserve the model tensor names and values.
Retained upstream terms do not assign an additional license to Phoenix-owned
weight contributions. The Phoenix-MWA code license is not a blanket license
for model weights, datasets or third-party assets. Attribution does not imply
upstream endorsement.
