-# OCI Digest-First Release Identity
-
-## Module
-ExportCenter
-
-## Status
-IMPLEMENTED
-
-## Description
-OCI distribution with digest-based artifact publishing and type-safe models is implemented.
-
-## Implementation Details
-- **OCI distribution client**: `src/ExportCenter/StellaOps.ExportCenter/StellaOps.ExportCenter.WebService/Distribution/Oci/OciDistributionClient.cs`, `IOciDistributionClient.cs` -- digest-based artifact publishing
-- **OCI distribution models**: `src/ExportCenter/StellaOps.ExportCenter/StellaOps.ExportCenter.WebService/Distribution/Oci/OciDistributionModels.cs` -- type-safe OCI digest and manifest models
-- **OCI distribution options**: `src/ExportCenter/StellaOps.ExportCenter/StellaOps.ExportCenter.WebService/Distribution/Oci/OciDistributionOptions.cs` -- configurable OCI registry options
-- **Registry config**: `src/ExportCenter/StellaOps.ExportCenter/StellaOps.ExportCenter.WebService/Distribution/Oci/OciRegistryConfig.cs` -- registry endpoint configuration
-- **Distribution target**: `src/ExportCenter/StellaOps.ExportCenter/StellaOps.ExportCenter.Core/Domain/ExportDistributionTarget.cs` -- export distribution target model
-- **DI extensions**: `src/ExportCenter/StellaOps.ExportCenter/StellaOps.ExportCenter.WebService/Distribution/Oci/OciDistributionServiceExtensions.cs`
-- **Tests**: `src/ExportCenter/StellaOps.ExportCenter/StellaOps.ExportCenter.Tests/Distribution/Oci/OciDistributionClientTests.cs`, `OciDistributionServiceExtensionsTests.cs`

-## E2E Test Plan
-- [ ] Verify digest-based artifact publishing uses sha256 digests
-- [ ] Test OCI distribution client pushes manifests correctly
-- [ ] Verify registry configuration supports multiple registries
-- [ ] Test type-safe models serialize/deserialize correctly
-- [ ] Verify distribution target resolution for different export types
