Struct ModelRouteDecisionPayload 

pub struct ModelRouteDecisionPayload {
    pub agent_role: String,
    pub model_id: String,
    pub tier: String,
    pub reason: String,
    pub signals_digest: String,
    pub price_snapshot: PriceSnapshot,
    pub est_cost_usd: f64,
    pub schema_version: u32,
}

ProtocolEvent::ModelRouteDecision payload (ADR §D5 observability). Kept as its own struct (not inlined into the enum variant) so host_router’s RouteDecision and this wire type can evolve independently — the seam maps one to the other explicitly.

Fields

agent_role: String

model_id: String

tier: String

"cheap" | "capable" — string, not host_providers::ModelTier, to keep this crate dependency-free.

reason: String

signals_digest: String

Opaque digest of the TaskSignal that produced this decision — enough for a hover tooltip / debug trail, not the raw signal (avoids leaking prompt text into the protocol log).

price_snapshot: PriceSnapshot

est_cost_usd: f64

schema_version: u32
