Class ModelSnapshotMutation

java.lang.Object

io.fluxzero.common.api.modeling.ModelSnapshotMutation

public class ModelSnapshotMutation
extends Object

Optional serialized snapshot consequence of one model target transition.

The SDK sends this only when the locally predicted target sequence is due for a snapshot. The runtime verifies that prediction against the assigned target sequence and adds the authoritative sequence and state index.
