A screw up in using a slitting saw

Yup, climb milling was one of the things that did you in. The other is a lack of proper cutting oil. Stainless likes to stick to cutters and requires a good grade of sulfur based cutting oil, Kroil is not cutting oil. I would also recommend using aluminum for the sacrificial pin and don't forget to take the backlash out of the feed screw before taking a cut.

You had the right idea using a sacrificial pin and the set-up for the first cut, it's just that with some machining operations, all it takes is one factor to make the whole thing go awry.
