F07-CJ: Yes
Rationale
CryptoAuth establishes communication bound to the remote node key; the derived IPv6 node address supplies its key-based reference. This credits the selected native cjdns endpoint, not unauthenticated address text, civil identity or application privileges. No new replay or forward-secrecy guarantee is inferred.
Assessment method
Individual review of inherited classification; no protocol execution
Source context
Primary specification / explicit endpoint and observer scope
