It's amazing how a good night's sleep will put things into perspective..
I went ahead and and fixed the popped splinter and inspected the area. There was a tiny pinhole knot that I didn't see before and that's why it popped right there. I braced the bow and mixed up a little epoxy and filled the crack, then let it down and clamped it. I think it's good but I'm going to re sinew the entire area I trapped just for good measure.
If it ain't broke, it ain't over!!
