My take? Retire that stem but don't sweat it. It was highly unlikely to get worse as long as it was sitting in the steerer undisturbed. Putting it back in and re-using it is iffy so I wouldn't. And I would chalk it up as a "good" failure. Any failure you detect at your workbench, vs on the road, is, in my book, a good failure.

Edit: I've never thought to study the slots on the TTT stems I've owned. Likely many had that same square detail. Never broke one and I used some of them many miles. My Peter Mooney went 25,000 plus miles on a new TTT bar and stem. I retired them because they had seen a couple of hard crashes. (I was worried more about the handlebars.) That said, I will have to look at all my stems and their slots. (My Nittos use wedges which has always struck me as a better system in addition to being easier to make. Among other things, diameter and fit tolerances matter far less with a wedge.)
