Struct AppState 

pub struct AppState {
    pub config: Arc<ProxyConfig>,
    pub http: Client,
    pub providers: ProviderRegistry,
    pub gate_health: Arc<GateHealthRegistry>,
    pub traces: TraceSender,
    pub adaptive: Option<Arc<Mutex<AdaptiveConformal>>>,
    pub tenant_rate_limiter: Option<Arc<DefaultKeyedRateLimiter<String>>>,
}

Shared state handed to every request handler. Cheap to clone: an Arced config, a pooled HTTP client, and a bounded channel sender.

Fields

config: Arc<ProxyConfig>

Static proxy configuration.

http: Client

Shared, connection-pooled HTTP client used to call upstream (observe passthrough).

providers: ProviderRegistry

Multi-provider registry used by the enforce-mode escalation engine.

gate_health: Arc<GateHealthRegistry>

Per-gate error budgets (auto-disable), shared across requests.

traces: TraceSender

Fire-and-forget sender to the background trace writer.

adaptive: Option<Arc<Mutex<AdaptiveConformal>>>

Optional online/adaptive conformal serve threshold (Gibbs-Candès ACI). None = fixed serve_threshold from config (default). When present, /v1/feedback nudges it live and the enforce path reads its current value per request — the reactive, self-tuning loop.

tenant_rate_limiter: Option<Arc<DefaultKeyedRateLimiter<String>>>

Per-tenant request rate limiter (ADR 0004 §D6). None (the default) disables rate limiting entirely — set via build_tenant_rate_limiter from ProxyConfig::tenant_rate_per_sec.
