  decode   : decode_psbt,
  finalize : finalize_psbt,
  parse    : parse_psbt,
  upgrade  : upgrade_psbt,
  version  : get_version,
  extract  : {
    global : {
      txdata : Extract.extract_txdata
    },
    input : {
      prevout : Extract.extract_input_prevout,
      sighash : Extract.extract_input_sighash,
      sigflag : Extract.extract_input_sigflag,
      witness : {
        segwit  : Extract.extract_input_segwit_data,
        taproot : Extract.extract_input_taproot_data
      }
    }
  },
  record : {
    global : {
      collect : Record.collect_global_record,
      find    : Record.find_global_record,
      get     : Record.get_global_record,
      has     : Record.has_global_record,
      remove  : Record.remove_global_record,
      update  : Record.update_global_record
    },
    input : {
      collect : Record.collect_input_record,
      find    : Record.find_input_record,
      get     : Record.get_input_record,
