- build one backend-neutral host per platform and package native runtimes separately
- compose immutable product-v2 bundles from verified host and runtime artifacts
- enforce host import policy and runtime provenance across release and SDK lanes
- align debug, release, Windows, Kotlin, and Swift validation with the composed product model
- update release documentation, CI topology, and agent guidance for the unified path
- require no-device client readiness and bounded clean shutdown for packaged runtimes
