   Everything else falls under section 1 alone, as Apache 2.0 or CC BY 4.0. In particular, none of the
   following is a Derivative Database of OpenStreetMap, and none of it is
   offered under ODbL or CC BY-SA:

     - the source code, which reads the data above and does not contain it
     - the rest of kierston/sim_data/: population, identity, kinship, ties,
       dockets, vehicles, holdings, accounts, devices, banking, towers and the
       other generated records
     - KDAY day exports (.bin), KSTATE checkpoints and KDIF scenario diffs
     - benchmark tasks, runs, scores and the paper
