Block forwarding of an onion message when the resolved next hop is the same peer that delivered it. Such a forward would immediately bounce the message back over the very connection it arrived on, which is never useful and can be abused to amplify traffic against a peer. The check runs after the routing action is resolved, so both direct next-node-ID and SCID-resolved paths are covered. A new `ErrSamePeerCycle` is returned (and logged at warn level) when a cycle is detected. |
