### Actionable Agenda Items:
- Who's taking notes?
- Nisha: are registries required to verify digests on push?
- Tianon: image-spec says SHOULD, no conformance test though
- https://github.com/opencontainers/image-spec/blob/v1.0.1/descriptor.md#verification
- Nisha: zot seems to not verify
- Jason: zot is listed as conformant
- https://github.com/opencontainers/oci-conformance/tree/main/distribution-spec/v1.0/zot
- [Jason] OCI recommending a header for manifest/blob pulls to denote the image ref that request is being made for
- help registry operators attribute pulls to images --> better rate limits
- build this into clients
- go-containerregistry prototype [here](https://github.com/google/go-containerregistry/pull/1369)
- Flavian: potentially also a useful signal for GC -- e.g., don't GC something that was implicated in a pull in the last N days
- Quay does something similar, where blobs are associated with a repo instead of a manifest until a subsequent manifest push references the blob; blobs only referenced by repos and not by manifests are GCed after ~1h.

### Presentation/Discussion Agenda Items:
- OCI Image support for Nix Store Paths:
- https://github.com/opencontainers/image-spec/issues/922

### Notes:

- Looking to store Nix data in OCI blobs
- Can't use layers because of overlay limits on number of layers
- Would use their own distribution-spec implementation
- Need some kind runtime to assemble filesystem without overlay for Nix components
- Nix currently has a cache, sometimes forced to rebuild on a cache miss, would like a registry to keep the store
- When glibc updates, all child objects in the store need to be recreated
