F06-LT: Yes
Rationale
Final-pair BCB-AES-GCM provides payload confidentiality across forwarding nodes that lack the final keys. LTP itself is not credited with encryption.
Assessment method
Primary-specification analysis of the explicit composition; no runtime execution
Source context
RFC 9173, BPSec default contexts
Outstanding qualification
Pin and validate the complete BPv7/SABR/LTP/Encapsulation/AOS executable composition, including security and local management. Documentary capability is not conformance or measured service.
