Struct ModelDefaults 

pub struct ModelDefaults {
    pub provider: String,
    pub model: Option<String>,
    pub fallback_order: Vec<ModelEntry>,
}

The user’s default provider/model, the fallback when none of a stage’s listed models has a registered provider. The CLI fills this from config.toml; an embedder sets it on the world builder (or leaves it empty, keeping the blueprint’s own entries as the last resort).

Fields

provider: String

The default provider name (e.g. anthropic).

model: Option<String>

The default model, if the user configured one.

fallback_order: Vec<ModelEntry>

The host-wide failover chain, from [providers] fallback_order.

Appended after a stage’s own entries and the user default, so a blueprint that names exactly one model still has somewhere to go when that provider stops answering. This is the case issue #201 reported: every stage named a single OpenRouter model, so there was nothing to fall back to when the account ran out of credits.
