C04-AX: No
Rationale
A classic NET/ROM Connect Request elicits a recognizable acceptance or refusal without cryptographic authentication. Callsigns, circuit fields and flow-control flags supply no secret probe gate or camouflage. This identifies a protocol response opportunity, not a claim that every node answers under every operating policy.
Assessment method
Primary protocol and pinned source analysis; no execution
