Where the heck are these metal shavings from?

Stator is fine, has a few gouges on the plate but the coils are perfect.
Cases have an interesting rub mark, and the flywheel is perfectly fine!!! I got lucky!

I have a minty bendix in a box of spare parts I have thankfully. The plan is to replace the case and flywheel cover bushing too.

Not wise to mismatch cases

Case bushing....

Bushing Puller

If you are going to REPLACE your bendix bushings here is a quick way to get them out.
1/2" Coarse thread tap, a nut and some washers:

Hold the tap stationary and tighten the nut, drawing the tap and bushing out:

Obviously it ruins the bushing, but you probably won't be pulling it if you aren't going to replace it. . .

In most cases, I think the weight plate breaks first allowing 2 weights to shift together and stretch and break the spring. When spring breaks, the bendix weights will often move outward and lock the bendix into open position. Your ski is running and bendix is still engaged with flywheel. Then it is spinning the front backwards at engine rpm until boom.

Good call to replace or at least check the bendix bushings! So many guys replace bendix into blown out case bushing and then get teeth damage to bendix and/or starter from the slop.

That sounds exactly like what happened! I got so lucky it didn't cause further damage. It must have been engaged for quite a while.
