Previously, discussions were still ongoing about different storage layouts that could support various access models. This changeset removes a layer of indirection that was in place due to earlier designs. Effectively, this both associates a layer with a named repository and ensures that content cannot be accessed across repositories. It also moves to rely on tarsum as a true content-addressable identifier, removing a layer of indirection during blob resolution.
