The external presentation of the changes required to facilitate the use of UTXO snapshots is the understanding that there are - now certain regions of the chain that can be temporarily assumed to be valid (using - the nStatus flag mentioned above).

Logic outside ChainstateManager should try not to know about snapshots, instead preferring to work in terms of more general states like assumed-valid. |
