I think I dodged a bullet on this one. After leaving the damaged area clamped overnight, it didn't look nearly so angry.
I taped-off the area with packing tape so that just the crack was exposed, which prevents the water-like CA glue from running on to the surrounding wood. I wicked-in the glue until it started to pool slightly on the surface, then got the taped caul and clamps back in place.
This morning I removed the clamps. By the veneer's change in color, I could tell that the glue had wicked back 5/8" to 3/4" and nothing felt spongy or loose.
A quick sanding removed the little bit of glue on the surface.
Wiping the area with mineral spirits gives a good visual indication of how it will look when I apply finish. The repair mostly fades away. I'll do one small touch-up, and I'll call that repaired. Whew!
