  • Af··· accurate, falsifiable, clear, novel, important — a capital is established, lowercase weak, unrated; no strip at all where nothing has been rated yet
  • [?] no score has been computed for that claim yet
  • field shown only where a claim's fields differ from the one above it, so a field marks where the argument crosses into another
