xcm-builder's DenyReserveTransferToRelayChain barrier is misleadingly named — it denies only the three outbound reserve instructions to the parent (InitiateReserveWithdraw / DepositReserveAsset / TransferReserveAsset with dest=parent); for inbound ReserveAssetDeposited from the relay it merely emits a debug log and continues. Inbound reserve-transfer defense must therefore come from IsReserve, not this barrier.
