You got the straight line right but you are missing the point. There is no "pattern" to a radially laced wheel other than right then left. The spokes are radial. They can go in one direction...straight from the hub to the rim. As simple as possible.

A simple concept that is wordy to explain. In essence, there will be no angle at the hub or the rim.
If they to not traverse on a directly radial path, it is because they were not laced to do so.
Yep. The spokes travel from the hub to the rim in a straight, perpendicular line. If spoke
#1 goes from the hub to the rim radially, then spoke
#2 , spoke
#3 , spoke
#4 , etc. will all go in the same straight line. I don't see any crossed spokes in the pictures so there isn't any other way to lace the wheel.

Tensionong the spokes would straighten things up in a hurry if the spokes were in fact laced radially.
It should but for some reason it didn't. I see the reason and I'll present it in a second.

However, even in a cross pattern laced wheel, the spoke from a trailing staggered flange hole would traverse to a trailing hole in the rim.
The pattern used on the OP's wheel laces the spokes from the trailing staggered hub flange holes to holes in the rim that lead the spokes that they trailed at the hub. Viewing photo
#1 shows the spokes pulling in opposite directions. This is the reason why.
Simple as that.
It is simple but not for the reasons that you are saying.

It may have been designed precisely that way.
Nope. Not designed that way. It a simple building error. Look at the first attached picture. Start counting from the valve stem clockwise. At spokes 12 and 13, you'll see that the two right hand spokes are attached to the same side instead of the correct left/right pattern. Spokes 14 and 15 are also both on the same side.
SumoMuffin: Detension the wheel. Swap what is now spoke 14 with spoke 13, so that you have one spoke running from the right and one running from the left. This should straighten out the hub.
