G04-BL: Yes
Rationale
Each Babel speaker computes routes from neighbor advertisements; multiple routers may originate a prefix or default. Additional routers can distribute forwarding/control work without a single mandatory coordinator. Periodic-update and per-router state costs remain, and no ten-billion-node capacity is inferred.
Assessment method
Primary specifications and pinned-code analysis; no execution
Source context
Babel routing protocol, RFC 8966
Outstanding qualification
Add routers and multiple prefix origins; inventory distributed work, update traffic and transient loops. No quantitative scale qualification.
