A source whose shape is only known at runtime (a host that accepts either).
The wiring is REQUIRED here for the same reason it is on the { storage }
branch: the compiler cannot tell which branch this call will take, so it
cannot know whether init would have built a fence. 'none' still applies
only to a { storage } source — a { DB } one is fenced regardless, so
choosing the opt-out cannot leave a database-backed runtime unfenced.
