G01-GN: No
Rationale
Explicit deployment refinement: use conventional globally routed IPv4/BGP, as already selected for IP and MQ. Edge defaults relocate global prefix reachability upstream rather than eliminate it. R5N discovery and CADET routing do not replace the selected UDP transport underlay. Partitioned peer discovery is compatible with this No: the global prefix tables reside in the declared IP infrastructure, not necessarily in each GNUnet peer. This is a whole-stack verdict for that deployment, not a theorem about every possible IP topology.
