Imperial Masterpiece
What do you mean?
As I recall this tree is planted with the saw cut flat on the bottom of the white pot anf the nebari is wide, taking up nearly the whole pot.
So its planted deep and I really wanna see what going on in there.....and give it more room to run.....but don't want to set it back.
in which case, letting it 'run' again is just going to create more inverse taper in the trunk? there is a swelling occurring at surface level due to the cluster of branches. damage is done, if was mine i would use the current flair at soil level as the new base.
its a hornbeam you could lift it out anytime to see whats going on. its not gonna die if you break a few root hairs!
Maros's ash is good inspiration for this
