Enum MessageMetadataField 

pub enum MessageMetadataField {
    Timestamp,
}

A metadata field that can be annotated onto a message.

New fields (e.g. the LLM model that produced an agent message, once stored messages record it) are added as variants here; each variant renders its own bracketed segment and may return None when the message lacks the data.

Variants

Timestamp

Message timestamp (Message::created_at), rendered as [time <RFC3339 UTC>]. For user messages this is when the message was received; for agent messages, when the reply was generated.
