Just saw the splash down. I think this was 100% successful test.

A composite overwrapped pressure vessel (COPV) seems to have exploded on the upper stage during reentry. It did significant damage to the rear flap and it made some dents in the engines too.

The rear flap was damaged before that explosion, not sure by what.

It's interesting to see which parts are critical at each stage of flight. Clearly those parts weren't needed by that point!

Yes, it was not the explosion what done it.

It looked like it happened during separation somehow.

Another copv failure? That’s what ripped open the starship during the ground test. Wtf I suspect that sub won’t be making copvs for spacex any longer.
