     A record stores canonical ids. Thus the lookup matches them the same as the resolver
     does: a prefix on either side.
 
+    A hop that the topology could not resolve keeps its short hash (``3d``), and several
+    nodes can start with it. The lookup then makes a guess: the first entry that matches.
+    The score leaves such a hop out, so the drawing can show a point that the score did not
