      summary: krnx_getAuxPowChainIDTag
      description: >-
        Returns the AuxPoW chain ID tag of the network the node is following.
        Merge-mining gateways commit this tag into the parent-chain coinbase, so
        a mismatch here is the first thing to check when a parent chain accepts
        blocks that KRNX then rejects.
