Tear in turbo intake housing is FOD damage. A piece of metal, gravel or welding spot that got loose. I guess you'll never know. Is compressor damaged? If not, then housing was probably mated with new compressor.

Shaft itself was probably overheated at some point due to oil starving. Bearing itself is made of much softer material so shaft can survive this better than bearing cartridge.

Anyway, this is much less of a problem than broken compression rings.
Thank you for your time,
