S01-GN: Yes
Rationale
Locally created peer keys and supplied contacts permit the selected independent private-IP deployment without a mandatory issuer, public hostlist or DNS authority. Local administration remains necessary. This does not establish global Internet reachability.
Assessment method
Primary specifications and pinned-code analysis; no execution
Source context
GNUnet v0.20.x peer identities
Outstanding qualification
Start isolated peers with local contacts, no hostlist/DNS/NAT helper; verify no authority lookup. Pin a runtime compatible with the historical handbook.
