Defining the diffID Generation Order in the Model Spec

[gaius-qi]

Model Spec uses files as layers and image layers have a sequential relationship, it should define a fixed order for generating diffIDs of files within a directory.

If use application/vnd.oci.image.config.v1+json as config media type now, Model Spec should consider how to define the generation logic of diffIDs to prevent containerd from generating different snapshots.

If use application/vnd.cnai.model.config.v1+json as config media type, the definition of diffIDs can be ignored, refer to #19 (comment).

Generating diffIDs in alphabetical order by file name is a simple solution.

I think the main issue is using the application/vnd.oci.image.config.v1+json as mediaType which makes it an invalid OCI Artifact.

I'm not sure I'm following here -- could you perhaps share an example of the problem?

DiffIDs in my understanding refer to something very specific (which only really applies to container images, not artifacts). Are we talking about the order of layers in the manifest?
