+summary: >-
+  Central OCC evidence for omnibase_infra PR #1889. The PR preserves the operator-supplied OMNI_HOME across
+  ~/.omnibase/.env sourcing, stages workspace sibling repos from that root for BUILD_SOURCE=workspace,
+  and passes BUILD_SOURCE, EXPECTED_BUILD_SOURCE, and OMNI_HOME as explicit Docker build args.
