F20-CJ: Yes
Rationale
At the pinned cjdns revision, SwitchCore.receiveMessage decodes the destination interface from the packet label, checks the shared interface slot, rewrites the remaining/reverse label and forwards. It installs no per-final-flow circuit entry for this transit operation. Neighbor CryptoAuth sessions and endpoint sessions remain; route discovery and shared interface state are not zero-state forwarding.
