The delivery repository's contracts and SDK live under modules/ as mesh-delivery-contracts and mesh-delivery-sdk, their Go module paths renamed to match the folders (the TypeScript names already did), and every importer in mesh-delivery, mesh-catalog, mesh-host, mesh-tools and mesh-sdk follows in the same group: a design as it should be, one path per module, checked by the group's check building every importer.
