Submit one strictly validated action for the run identified by runId. Use a payload variant allowed by the latest observation. Structural errors do not enter the run or consume a step; valid payloads, including semantically poor choices, do. Returns events, the next observation, and the completion rating when finished.
Choose a variant allowed by the latest observation. Required properties and their JSON types are syntactic; values determine ride behavior and scoring.
