+Node depth:
+
+The "04 00 00 00 04 00 00" is the number of nodes above the node, in
+this case 4, three Headings and the Output node. The first 04 is
+reliable, the second one is sometimes 01.

+The node numbering is insane: in decimal each node's number decreases
+(these numbers are negative) by 2000 then by 34 alternately, except
+that if a node is collapsed it *increases* by 2000 then decreases by
+2000. Below (test15.spo), LogI and LogN are collapsed:
