🔴 HIGH — partial success reported as a hard error, leaves an orphan. Reproduced twice: create_primitive with position:[9,9,9] returns error "Accessed JArray... Int32 array index expected" (ParseVector3 @ MCPServerMethods.Reflection.cs:432) — but the object gets created anyway (orphan -3032). An AI agent sees "error" → retries → duplicate GameObjects pile up. Root cause: it mutates then validates args, with no rollback.
