+Stream columns named `FLAG_TO_MUTATE` means they are extracted from the `FLAG_AS_EXTRA` RAPIDS column. You can refer to [OS complex mapping](../../datastreams/add-new-data-streams/#os-complex-mapping) section for detailed information.

 !!! hint
     The mappings in this stream (RAPIDS/Stream) are the same names because AWARE data was the first stream RAPIDS supported, meaning that it considers AWARE column names the default.
