Module snapshot 

World snapshots — serializable representations of the entire game state.

A WorldSnapshot captures all entity components and named resources at a single point in time. Snapshots are used by the save/load system, the checkpoint system, and the network replication layer.

Diff / incremental saves

WorldSnapshot::diff produces a SnapshotDiff describing what changed between two snapshots. This is used for incremental save files and for network state synchronisation.
