(Why 126 Kelvins? Because that's the temperature that I get when I plug the Snow Line radius into the formula in step 25. I'm seriously considering using 125 Kelvins instead, since it's a nicer number and I doubt that one Kelvin out of 126 will trash the system.)

Step 21, placing a predesigned world: R = (126/B)^2 * Rs
Step 25, blackbody temperature: B = 126 / square root of (R / Rs)
(In both cases, Rs = snow line radius.)

World Type Assignment Table: I pencilled in a column giving appropriate orbital radii as percentages of the snow line radius.

I've replaced the luminosity-based Inner Limit with 0.2% of the Snow Line radius. It requires computing the Snow Line before computing the Inner Limit; but that's not a major problem IMHO.
I find this is going to be extremely helpful with the white dwarf system I'm currently working on. I mean I know they have a stated luminosity of .001, but there have got to be exceptions, and I like to do the math to see what happens.
