Enum MessageRole 

pub enum MessageRole {
    User,
    Assistant,
    System,
}

Wire message roles.

Grok’s enum is User | Assistant only; we add System for the mid-conversation-system beta path (DeveloperRendering::MidConversationSystemBeta, plan §4.1) — never emitted under the portable default.

Variants

User

A human / tool-result turn.

Assistant

A model turn.

System

A mid-conversation system message (beta-gated; see enum docs).
