Remarks
A projection may only consume events, never another read model, so a value that has to be joined in from a second read model can only be filled in by the query that serves the model. Without a way to say so, such a member is indistinguishable from one whose mapping was simply forgotten - which is exactly what the analyzers report it as. This states the intent, so the member is left alone: AutoMap will not bind it even when a subscribed event happens to carry the same name, and it is not reported as unmapped.
