At least it was not a Wing Spar Crack/Connection Failure.

Quote. "According to the outlet’s sources, the cracks emerged during routine pre-delivery inspections at Boeing’s Everett, Washington facility, where technicians identified anomalies not on the wings or control surfaces but within the airframe’s primary and secondary structural components."

This is odd for a new aircraft.
My first wild guess is that some joint shims were not installed and fasteners pulled together the gap causing cracking.

Pre-delivery cracks? That sounds really bad. They're cracking before any loading or exposure occurs.
