State

class State(initialState: Map<String, Any> = emptyMap(), initialDelta: Map<String, Any> = emptyMap()) : Map<String, Any>

A thread-safe state map that maintains the current value and tracks modifications.

This class implements Map to provide a read-only view of the state, while exposing specific mutation methods (set, putAll).
