How the list is made
  • Every figure names whoever published it. “No published figure” is an answer, not a gap.
  • Each name has a standing file, updated as the story moves, with a dated changelog.
  • The list is updated every week. When a name moves, it shows how many places it rose or fell.
  • No minors. No one is listed for a relationship they have not made public.
