Struct MessageAlternative 

pub struct MessageAlternative {
    pub content: String,
    pub images: Vec<ImageRef>,
    pub content_blocks: Vec<ContentBlock>,
    pub timestamp: String,
    pub provider_key: Option<String>,
    pub model: Option<String>,
}

Stored alternate body for a regenerated assistant message.

Message keeps the currently selected alternative in its top-level content/content_blocks fields so existing clients and prompt assembly keep reading the active response. alternatives stores every selectable candidate, including the active one.

Fields

content: String

images: Vec<ImageRef>

content_blocks: Vec<ContentBlock>

timestamp: String

provider_key: Option<String>

Provider key that minted this alternative’s content. A regenerated assistant body can be produced under a different provider than the original message or a sibling alternative, so each alternative carries its own provenance rather than inheriting the single Message::provider_key. The replay portability filter uses this to drop opaque thinking data the active provider cannot interpret. None for alternatives persisted before per-alternative provenance tracking, in which case callers fall back to Message::provider_key.

model: Option<String>

Model id that minted this alternative’s content. Like MessageAlternative::provider_key, each alternative carries its own provenance because regenerated bodies can come from different models. None for alternatives persisted before model provenance tracking, in which case callers fall back to Message::model.
