F10-GN: No
Rationale
Normal payload dispatch removes one queue entry and passes its envelope to one selected connection. It does not fan out proactive copies of that item across the ready connections. Reliable-channel retries and repeated control messages are recovery mechanisms, not the proactive diverse-path duplication tested here.
Assessment method
Pinned release-source analysis and primary protocol review; no runtime execution
