Built a rear wheel with an H PLUS SON rim and Gran Compe fixed gear hub

Another wheel day (and so on).

I built up a rear wheel with an H Plus Son triangular section polished WO rim and
a Gran Compe double-threaded fixed gear hub.

Gran Compe II hub, 32H, fully Compe laced JIS pattern.
I'll do the lacing later.
The hub isn't new—there were marks from previous JIS lacing—
so I threaded the spokes following that pattern.
I'm a bit uncertain about placing inpoke neck-wrench marks over existing ones on the outside of the hub flanges,
but if I offset the spoke holes by one,
the hub would end up with inpoke marks in every hole, which also feels wrong.
The hub body had no reference marks like
a logo or print that would be visible when looking through the valve hole
at the correct assembly position.
If it did have such marks, and the previous wheel had aligned the valve hole
with the hub body's phase reference, then on the next wheel build
I couldn't offset the hub flange neck marks.

Silver spokes with black aluminum nipples is the customer's request, but

it matches the black lettering on the rim sticker.
This sticker is the only reference for the rim's left and right orientation, but

↑No mounting mark
Although the hub has no left-right reference,
I built the wheel treating the side that previously had a cog mounted
as the right side.
