Thanks : )
Yes I think under the mudguard is my preferred method.
The frame builder won't drill the forks for internal routing so we're using little loop-shaped braze-ons to pass it up the inside of the fork blade.It's the exact details of how it changes direction at the top of the fork blade and goes under the mudguard that's difficult to find proper info on.
So far I'm thinking the journey looks like this, with unresolved bits in bold:
- Out of the back of the light
- Through a little rubber grommet (maybe an angled one like this to get the transition smoother)
- Under the mudguard somehow (how do you secure it safely under there?)
- How does it get from under the guard to the first loop at the top of the fork blade?
- Then down the fork to the connector on the hub.
Here's a picture of it mocked-up on my (very dirty) other bike:

Trad constructeur solution is to run it along the edge of the metal mudguard - you can crimp it in the rolled edge - but a) the PDWs don't have a rolled edge and b) the Supernova's cable is fairly chunky (is it coax?).
Securing the cable under the guard can be tricky; I think some people use silicone sealant? Or Gorilla Tape? I guess you want something that's potentially removable. Whether it's better along the mudguard centreline or along the edge may be determined by the clearances.
With the cutouts in the guard under the crown I'd have thought you could run it straight up the fork blade and then just fix it to the underside of the guard, effectively making a 90° turn.

Can you put another grommet on the side of the mudguard, and an adjacent eyelet as high up the fork leg as possible? The hard part is going to be keeping it off the tyre.
Duct tape should protect the cable a little bit from tyre rub. Not likely to be a problem on your front mudguards but can be on rears.

Thought about this for my bike, VO guards though. Are you confident the guard is stiff enough so the light won't bounce or wobble a bit? Small bounce = big beam movement. I was thinking of a strut like a rack support that went from the fork mid eyelet and looped over the guard. It'd need an L bracket to fit the guard and light but that's what custom builders are good, at right?

Up the inside of the fork blade and out at the top, then through the mudguard? Or if there's enough clearance, up the inside of the fork and then just along the edge of the mudguard (do the PDWs have rolled edges?).
