# @open-matrix/hivecast-sdk Public HiveCast actor SDK facade for package authors. Prefer narrow package imports when a package only needs one layer: ```ts import { MatrixActor } from '@open-matrix/core'; ``` Use this umbrella package when a package intentionally needs the combined actor, browser host, contracts, federation, and Omega kernel facade. Import browser app build utilities directly from `@open-matrix/browser-kit` so headless actor packages can import `@open-matrix/hivecast-sdk` without loading browser-only custom element code.
