Where's the source code for sourcedir from script_uris?

[neo]

I notice if I call script_uris.retrieve it would return something like:

s3://jumpstart-cache-prod-us-east-1/source-directory-tarballs/stabilityai/inference/txt2img/v1.2.2/sourcedir.tar.gz

I wonder whether this "source-directory" is open source somewhere 🤔
