Parallel

Purpose

Run unique valid child branches concurrently and wait for all branches or the first completed branch.

Key inputs / outputs

• Inputs: events (NodeReference[]) and mode (WaitAll or WaitAny).
• Outputs: none.

Success / Failure semantics

• An empty list succeeds immediately; otherwise the node yields while the selected completion condition is pending.
• Completed branches resolve to success unless one or more branch stacks report exceptions.

Important limitations

• Missing references and duplicate references are skipped.
• Each scheduled branch uses an independent runtime call stack; stopping Parallel ends those stacks.
