Imperial Masterpiece
If the branch stem is still green latent buds likely are OK. If the trunk stays alive it wants to live so should grow in the Spring. This is close enough to Fall it could assume an early dormancy but did not have a chance to put leaves energy into storage in the roots so expect it to need some extra boost once it wakes up in the spring. Being in the bay area is fairly mild climate and I would not protect the tree except for maybe putting the pot into a bigger container of soil for the roots temp stability. Let it grow OUTDOORS when it is ready to grow on its own without artificial protection.
