Two endpoints, one registry
Repository metadata is served over the AWS API on the gateway endpoint. Image data moves over the OCI Distribution /v2/ endpoint on that same host, authenticated by the bearer token GetAuthorizationToken mints for docker login.
The split explains the largest group of unimplemented operations below. The layer-transfer operations — BatchCheckLayerAvailability, InitiateLayerUpload, UploadLayerPart, CompleteLayerUpload and GetDownloadUrlForLayer — are registered stubs because the /v2/ endpoint carries that traffic instead. A client using docker or any OCI-compatible tool never calls them.
Vulnerability scanning is not offered, so the image-scanning operations refuse deliberately rather than pretending to have found nothing. Registry replication is likewise absent: a deployment is a single registry, with no cross-region peer to replicate to.
