Struct StageRouterConfig 

pub struct StageRouterConfig {
    pub mode: PickerMode,
    pub confidence_threshold: f64,
    pub recent_window: Option<usize>,
    pub handoff_notes: Option<HandoffNoteConfig>,
    pub tier_prompts: TargetPrompts,
    pub llm_fallback: Option<LlmFallback>,
}

How a stage router scores turns, and what it hands the model it picks.

Fields

mode: PickerMode

Tier a turn falls open to when the scorer is not confident.

confidence_threshold: f64

How much corroboration a decisive pick needs, in [0.0, 1.0].

recent_window: Option<usize>

Trailing tool results the signals are computed over. None uses DEFAULT_RECENT_WINDOW.

handoff_notes: Option<HandoffNoteConfig>

Note handed to the model on a signal-driven escalation, and on a hand-back to the efficient tier when a de-escalation note is configured.

tier_prompts: TargetPrompts

System prompts keyed by target, handed over on every turn that target serves. Empty by default.

llm_fallback: Option<LlmFallback>

Capability judge consulted on turns the signals leave undecided — the judge’s own target, plus the same configuration the standalone capability route takes.

Implementations

impl StageRouterConfig

pub fn new(mode: PickerMode, confidence_threshold: f64) -> Self

The signal-only configuration: no notes, no per-tier prompts, no judge. Set the optional fields to add them.
