## Verification Evidence

### Registry API Manifest Headers
This section displays registry manifest verification logs, ensuring the matching `Docker-Content-Digest` is resolved.

```sh
# Fetch Core (Mattermost) manifests from registry
$ curl -fsSI -H 'Accept: application/vnd.docker.distribution.manifest.v2+json' https://toki-labs.com:5050/v2/nexo/mattermost/manifests/latest
HTTP/1.1 200 OK
Server: nginx/1.29.3
Content-Type: application/vnd.docker.distribution.manifest.v2+json

# Fetch Push-Proxy manifests from registry

### Remote Host Image Inspect (Architecture Proof)
This section lists concrete inspection output executed directly on the remote Mac build host (`toki@toki-labs.com`).

```sh
$ ssh toki@toki-labs.com '/usr/local/bin/docker image inspect toki-labs.com:5050/nexo/mattermost:latest --format "{{.Os}}/{{.Architecture}} {{range .RepoDigests}}{{.}} {{end}}" && /usr/local/bin/docker image inspect toki-labs.com:5050/nexo/mattermost:v11.4.2-arm64 --format "{{.Os}}/{{.Architecture}} {{range .RepoDigests}}{{.}} {{end}}" && /usr/local/bin/docker image inspect toki-labs.com:5050/nexo/push-proxy:latest --format "{{.Os}}/{{.Architecture}} {{range .RepoDigests}}{{.}} {{end}}" && /usr/local/bin/docker image inspect toki-labs.com:5050/nexo/push-proxy:v11.4.2-arm64 --format "{{.Os}}/{{.Architecture}} {{range .RepoDigests}}{{.}} {{end}}"'
