F26-AX: No

Rationale

The selected classic AX.25/NET/ROM composition uses callsigns, announcements and circuit state without an authenticated forwarding-authority gate. A syntactically valid callsign or circuit is not proof of authorization to consume subsequent links.

Assessment method

Primary architectural and forwarding-policy analysis; no bandwidth benchmark required

Source context

Selected composition and retained source assessment; new F26 criterion

Outstanding qualification

Administrative port provisioning, radio licensing and endpoint application login do not provide the missing incoming-frame authority check. No extra link-security mechanism is selected.
