To enable cross-actor communication in XState v5, register actors with unique systemIds for global addressing. This allows any actor to retrieve and communicate with another using system.get(), bypassing strict parent-child hierarchies.

Global actor addressing in XState assigns unique systemIds to actors for system-wide access. You need it when components like a notification actor must send messages to UI actors that are not direct children in the hierarchy.

You send a message to a specific actor by retrieving it with system.get() using its registered systemId. Once retrieved, you can directly send events, such as a notify event with a message payload, to that actor.

Yes, XState v5 supports communication beyond parent-child hierarchies by utilizing actor systems. Actors can be registered with unique systemIds and accessed globally to facilitate complex cross-actor communication patterns.

Using systemIds for XState actor communication requires actors to be registered before they can be retrieved with system.get(). This approach manages global addressing but depends on the system hierarchy being properly established.
