One day I'll learn to stop fixating on negative constraints. Missed a "6 with a dot forces a 1" for the longest time because I was trying to figure out if the six meant anything for the non-dot sides.

Just for sure: There is a negative constraint on green dots?

Reply: yes there is. :-)
I will update the text, because there can be the same interpretation issue as there was with SVS #408.
