...Yes, We All make Mistakes! Part of Being Human. Here's what I Know:

After receiving a Set of Clevite 7 Rod Bearings, in the scope of 'Assume Nothing', I Inspected Each and Every Piece. I ordered the set in .010" Over, as the Crank had been Re-Ground/Polished .010 Under.
All Half Bearings were stamped .010, Excepting for ONE Single Half...was Stamped .020, ofcourse I sent the entire set back and then received back a complete and correct set. Is this what happened in Your case, as You pointed out, we'll Never know.

Next, Before Disassembly of the Rotating Assembly, it is Prudent to FIRST, before All, Stamp the Number of the Cylinder on all Rod Caps, Both Halves, Cap and Rod, 1 Thru 8, As they are Viewed When Rotating the Crank to Access. So with the Stamped Numbers, one would have to slip-up on the Details or be Distracted, in Order to Install the Cap Backwards. Without the Numbers on the Rods/Caps it would be Impossible to know Which Cylinder the Rod Goes To!? Unless one was very well organized and did the Rods One at a Time.

I concur with the Boss, Crank Journals are welded and reground Every Day! Just be sure to take it to an 'Experienced' Crank Shop of Experts.

P.S. In My Opinion, 4-Bolt Mains with ARP STUDS is the Only way to Go. Maximum Rigidity! That's the Way I built My Shortblock. Even used ARP STUDS on the Heads, Especially.
