I always build Archetypes with the spokes crossing the centre, as you put it (I think!).
On a rear wheel viewed from the DS, first spoke to the right of the valve hole always goes to NDS hub flange, while its corresponding larger hole inside the rim is offset slightly to the DS.
The spoke holes all pass through the centreline pointy bit of the rim profile, but are drilled at an angle alternating with each hole (I think; also can't check right now), and the larger holes inside the rim are offset as a result.
To build 'one spoke over' would put a lot of stress on the nipples and rim's nipples bed, potentially leading to spoke or nipple failure, or some kind of rim fatigue failure as a result of the nipple bed being twisted this way and that.

I’m replacing a worn 32 hole archetype laced with dt comp spokes to dt240 hub, 3 cross, built by a chap that I rate. My intention is to reuse the spokes.
I’ve done this a fair number of times and I tape pairs of spokes together, loosen them off gently going round the wheel. Then transferred the lot to the new rim
However, the spoke holes in the archetypes have quite a large offset stagger, and the spokes are laced so they cross the centre (so that a spoke goes from the left side of the hub to the right side offset hole in the rim). I assumed that a spoke always goes to a hole closest to minimise the angle of entry to the rim.
So, either the “handedness” has changed on the new rim compared to the old (which went in a recycling bin a week ago so I can’t check), or the chap laced it so the spokes cross over to the opposite side (and I can’t check that till Tuesday).
I don’t want to move the spokes from the pattern they’ve been in (as everything has worn into place). I can just “advance” the spokes on the rim to get the correct line up - but I’ll have to deal with spikes crossing over the valve hole.
Any views? Is it normal for the same rim to come in different handedness? Or is crossing spokes to the far offset hole accepted practise?
