# OCI Referrer-Based Artifact Association
## Module
Cli
## Status
VERIFIED
## Description
OCI referrer-based attachment of SBOMs, attestations, and verdicts to image digests using the OCI referrers API, with discovery, publishing, and fallback mechanisms.
## Implementation Details
- **OCI Registry Client**: `src/Cli/StellaOps.Cli/Services/OciRegistryClient.cs` / `IOciRegistryClient.cs` -- OCI registry operations including referrers API
- **OCI Attestation Registry**: `src/Cli/StellaOps.Cli/Services/OciAttestationRegistryClient.cs` -- attestation-specific OCI operations
- **Commands**:
- `stella oci-list <digest>` -- list OCI referrers for an image digest
- `stella oci-verify <digest>` -- verify OCI-attached attestations
- **Architecture**: Uses OCI referrers API (fallback to tag-based discovery for older registries)
## E2E Test Plan
- [ ] Run `stella oci-list sha256:abc123` and verify referrers listed (SBOMs, attestations, verdicts)
- [ ] Run `stella oci-verify sha256:abc123` and verify attached attestation verification
- [ ] Verify fallback to tag-based discovery when referrers API unavailable
- [ ] Verify SBOM attachment discovery and content retrieval
- [ ] Verify `--format json` output
## Verification

- **Tier 0 (Source)**: pass -- all referenced source files exist on disk
- **Tier 1 (Build)**: pass -- module builds cleanly, 339 tests pass in StellaOps.Cli.Plugins.Tests
- **Tier 2d (Integration)**: pass -- targeted integration tests confirm behavioral correctness
- **Test Project**: `src/Cli/__Tests/StellaOps.Cli.Plugins.Tests/StellaOps.Cli.Plugins.Tests.csproj`
- **Evidence**: `docs/qa/feature-checks/runs/cli/oci-referrer-based-artifact-association/run-001/tier2-integration-check.json`
