Metal Shavings Behind LN IMS Bearing - Need Advice!

Or a hack installed the bearing and left debris from a previously failing bearing in the tube/ engine.

Short of tearing the engine down, is there a way to confirm this is the problem?

I don't understand why anyone would trust a $20 bearing for this application!!!
If its a cheap iron bearing, these can definitely show signs of magnetic wear like this... but what kind of shop would do that??? Some shops really need to keep their fingers out of engines - Scary!

No.. Even torn down you must measure for drive runout to find this issue.
