Struct LlmFallback 

pub struct LlmFallback {
    pub judge_target: LlmTarget,
    pub config: TaskClassifierConfig,
}

The capability judge a stage router falls through to.

Fields

judge_target: LlmTarget

Target the judge model is called through. It is not a routing destination, so it does not belong in the router’s target set.

config: TaskClassifierConfig

Judge configuration. recent_turn_window is worth setting to this router’s recent_window so the judge reads the same span the signal scorer scored. Note: session_affinity and message_hash_fallback have no effect here — the judge runs as a cascade classifier, not a standalone algorithm.
