Container Registry Images not consuming storage

I’ve pushed two private images to GitHub’s container registry, where my Free Org is supposed to have a 0.5 GB limit. The total space, according to docker image ls is 1.7 GB and 1.3 GB. My billing still shows virtually no storage used.

What’s going on? In general, if the image uses layers that GitHub may already have cached, do those count against my storage, or not?

Thanks!

In case anyone else finds this and needs to know the answer - as of 9/1/2021, the Container Registry consumes no storage. This won’t be permanent, though.

All Storage currently consumed in Billing accounts for packages and artifacts created by GitHub Actions.
