-For repository storage, use Git LFS or a Gitea release/package store:
+Weights must remain local to the deployment machine. Do not push `.pt`, `.pth`,
+`.onnx`, `.engine`, or `weights/files/` into Gitea. The repository stores only
+code, `weights/manifest.json`, and helper scripts. Before pushing, run:
 
 ```bash
-git lfs install
-git lfs track "*.pt" "*.pth" "*.onnx" "*.engine"
+scripts/check_no_weight_git.sh
 ```
 
-If Git LFS is not available on the host or server, keep the copied weights on
-the deployment volume and commit only `weights/manifest.json`.
+If a deployment machine needs weights, run the sync command locally on that
+machine after cloning the code.
