# Attribution and license scope

Phoenix-RoboTwin distributes the Phoenix-MWA RoboTwin post-trained step-35000
policy. It is derived from Wan2.2-TI2V-5B and changes the checkpoint metadata
schema to the Phoenix name without changing its 1,653 inference tensors.
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 .

The two frozen C2C/C2R packages provide initial scenes, observations and
instructions for evaluation using RoboTwin (https://github.com/RoboTwin-Platform/RoboTwin).
They are not training demonstrations or expert action sequences. Simulator
code, CuRobo, robot/object/texture assets, WanVAE, T5 and tokenizer are obtained
separately under their upstream terms. DINO/CSVAE weights and their notices are
distributed separately in OpenPhoenix/Phoenix-Encoders.

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, evaluation records or third-party assets. Attribution does
not imply upstream endorsement.
