+# Prompt2MotionSystem-LFS
+
+Public large-file distribution repository for [Prompt2MotionSystem](https://github.com/AlayaLab/Prompt2MotionSystem).
+
+The repository name keeps the `-LFS` suffix, but Hugging Face currently stores and transfers large files through Xet. Consumers should use `hf download`; Git LFS is not required.
+
+> Status: repository initialized. No runtime model or Unity asset bundle has been published yet.
+
+## Planned layout
+
+```text
+licenses/
+unity/
+  test-characters/<asset>/<version>/
+  test-motions/<asset>/<version>/
+models/
+  hy-motion/<version>/
+```
+
+Each published artifact must have a fixed version, checksum, provenance, and license record. Unity bundles must include their committed `.meta` files so GUIDs remain stable across machines.
+
+The GitHub repository is the installation source of truth. Its README and lock manifest will pin a full immutable Hugging Face commit SHA; agents must not install from the floating `main` branch.
+
+## Asset boundary
+
+Only files that AlayaLab is allowed to redistribute publicly belong here. SWAT, MotionSet, other purchased assets, credentials, sessions, and game-specific adapters are excluded. Those remain in separately licensed consumer projects such as `mcp-anim-playground`.
