## Returns

`Promise`<
| [`OpenAIResponsesInputItem`](../../types/type-aliases/OpenAIResponsesInputItem.md)
| `null`>

## Remarks

A USER message, or a peer-identity ASSISTANT message (a message from an assistant identity that
is not this adapter's own `selfIdentity`), renders as a plain `role`-carrying input message item
— the ADK's own prior assistant turns are NOT routed through this renderer; the caller renders
those via renderOpenAIResponsesOwnAssistantMessage instead, into the OUTPUT-message shape
the reasoning-pairing validator expects (see the module's Known Gotchas).
