+## Add inter-hub chart handoff

+status: done

+
+Added `charts/inter-hub` and `helm/inter-hub-values.yaml` so IHUB-WP-0018 has
+a concrete Railiance app handoff chart matching the existing railiance-apps
+layout. The source Inter-Hub repo remains the owner of the runtime app code,
+workflow, and SOPS secret handoff.
