Round Robin

Round Robin returns the first option on its first run, the second on its next run, and wraps back to the beginning after the last option.

Input

Input	Type	Required	Description
Options	Repeatable any	Yes	At least one value in rotation order.

Output	Type	Description
Selected	Any	The option at the current rotation index.

The current index is stored for this node instance within the project. With [A, B, C], successive runs return A, B, C, A.

Changing the number or order of options does not reset the stored index. The next run applies that index to the new list.

Simultaneous runs can read the same index before either saves the next one. Serialize runs when each option must be chosen exactly once per cycle.
