Networking Security Review
The review covers Curve25519 identity, HKDF context separation, ChaChaPoly nonces, identity/pairing/transcript binding, sequence and replay rejection, authenticated heartbeat, reconnection, revocation, Keychain storage, log redaction, and command authorization. Existing deterministic tests cover authenticated envelopes, replay and identity failure, and revocation. Independent cryptographic review remains required; a future standard-TLS design may reduce custom-protocol risk.
