I need a way to do what layer weight does as if the view were orthographic

But I have no idea where where to find Layer Weight in the source code or how to reimplement it such that it takes its window vector from a single point.

I think you can use the “normal” and “incoming” outputs of the geometry node for this:

Apparently, this is the formula for the “facing” output:

What is it that Layer Weight node's Facing output is supposed to be?

that was just part of the formula… For the layer value output, here’s the complete formula: if blend in [0.0, 0.5[: result = 1 - pow(dot(N,I), 2*blend) if blend == 0.5: result = 1 - dot(N,I) if blend in ]0.5, 1.0[: result = 1 - pow(dot(N,I), 0.5/(1-blend)) note there are clampings everywhere and the blend value never gets to reach 1.0, as it’s clamped to 0.9999 (1.0 - 10^-5)
