Expand description

Checks a runtime: driver artifact’s imports against the stream interface this host serves.

Refuses a component importing any murmur:text/* instance, or any murmur:stream/* instance other than exactly WIT_STREAM_EVENTS_IFACE: the host serves neither, so the driver would fail to instantiate on its first turn. contracts is what murmur_artifact::extract_wit_contracts read out of the driver’s wasm; None, and a component importing neither package, pass.
