    The requested operation-context surfaces are now available on main. #755 supplies the SerDes part: the context-aware serialization/deserialization overloads receive SerDesContext with the stable durable execution ARN and payload entity ID, while default methods preserve existing serializers.

    The public waitForCondition check function and waitForCallback submitter already receive StepContext; those existing APIs were verified alongside the new SerDes overloads on current main (2b2f930a). PR #755 provides operation-payload serialization context; ordinary Lambda input/output serialization retains its existing path. Closing this request for context in operation user functions as completed.
