Struct Escalation 

pub struct Escalation {
    pub max_rungs_per_request: u32,
    pub session_promotion: Option<SessionPromotion>,
    pub speculation: u32,
    pub serve_threshold: Option<f64>,
    pub adaptive: Option<AdaptiveConfig>,

}

Escalation limits and session-level promotion.

Fields

max_rungs_per_request: u32

Hard ceiling on rungs climbed within one request.

session_promotion: Option<SessionPromotion>

Optionally start higher for the rest of a session that keeps failing.

speculation: u32

Prefetch depth: fire this many rungs ahead concurrently to trade wasted spend for latency. 0 (default) is serial — one call at a time. The served result is identical either way.

serve_threshold: Option<f64>

Calibrated conformal serve threshold: a rung is served iff its aggregate gate score is >= this value (SPEC §10.1). None (default) keeps the original rule — serve iff the aggregate gate verdict is Pass — byte-identical to today.

adaptive: Option<AdaptiveConfig>

Online/adaptive conformal (Gibbs-Candès ACI): when set, the serve threshold is tracked live from deferred feedback instead of held fixed, so served-failure stays at target under distribution shift. None (default) uses the fixed serve_threshold above — byte-identical.

enforce_structured: bool

Opt-in: route tool-calling / multimodal requests through enforce instead of falling back to observe (ADR 0005). false (default) is byte-identical to today — such requests pass through un-gated. Turn on only after verifying enforce faithfully round-trips your tool workload; content fidelity is preserved either way, but escalating a live tool turn is operator-gated.
