If we're forwarding I/O entries from one environment to another and we hit entries with null environment that suggests it's client entries. Like scripts or RSC stream entries loaded into the current server environment. From the perspective of the consuming client, those are not "client" entries but rather I/O that happened on the server.

If we're forwarding I/O entries from one environment to another and we hit entries with null environment that suggests it's client entries. Like scripts or RSC stream entries loaded into the current server environment. From the perspective of the consuming client, those are not "client" entries but rather I/O that happened on the server.
