I've seen half a dozen wrong-forked assemblies in the last decade. Recently, I had a neighbor bring me a child's bike that had been assembled backward by her husband. Her neighbor brought me a dept. store MTB with a reversed fork. It's not that unusual, I guess.

Bonus points to Pacific for requiring the assembly stickers to prevent workers from doing this. Note the "Front" sticker on the fork crown in the photo, taken from an Amazon-level MTB recently donated for me to reconfigure for a local underprivileged boy to ride.
