A conversation item in the Realtime API.

Discriminated by the type field:

• message — a text/audio/image message (system/user/assistant)
• function_call — a function call issued by the model
• function_call_output — the result supplied by the client
• mcp_call — an MCP tool call issued by the model
• mcp_list_tools — MCP list-tools result
• mcp_approval_request — server asks client to approve an MCP call
• mcp_approval_response — client approves/denies an MCP call

Content-part / role constraints

The OpenAI spec restricts which content-part types are valid per role:

• system → input_text only
• user → input_text, input_audio, input_image
• assistant → output_text, output_audio

Serde does not enforce this. Call [RealtimeConversationItem::validate()] after deserialization to check these invariants.
