How much bearing damage is too much

So the engine was just rebuilt like 7 years ago. 10k miles and regularly driven just not very far. Doesn’t mean the parts they used to rebuild were not older or stored improperly.

Engine is going to the shop. A list of stuff I was already doing is above. This just set my timeline back. Engine shop will do these bearings and check everything else out while in their hands. Thanks for the info though, I can see how that is more of a delam issue versus gouging.
If the motor is fresh could be the cam bearings were not replaced or if new the clearance was tight and they got hot.
