F39-CJ: Yes
Rationale
The selected UDP application addresses a cjdns key-derived IPv6 endpoint and service port, independently of its underlay locator. Ordinary host routing delivers a locally assigned virtual address locally; a remote virtual address goes through the cjdns TUN and key-based routing. The same logical endpoint form and UDP interface cover both cases.
Assessment method
Primary documentation, pinned source and explicit architectural composition; no runtime test
Source context
Peer-ID stream API and identity-derived virtual-address delivery
Outstanding qualification
Constructive architectural assessment for the declared native cjdns-node addresses, not devices behind imported IP tunnels. Bind the service to the virtual address or wildcard and allow it in local policy. The identity belongs to the node; the port distinguishes its service. Local delivery need not traverse CryptoAuth, and no local security equivalence, zero-copy, process migration or runtime certification is inferred.
