#![deny(missing_docs)]
//! Provider-layer resilience middleware for the Brainwires Agent Framework.
//!
//! Wraps any `brainwires_core::Provider` with composable decorators:
//!
//! - [`RetryProvider`] — exponential backoff with jitter on transient failures.
//! - [`BudgetProvider`] — atomic token/USD/round caps with pre-flight rejection.
//! - [`CircuitBreakerProvider`] — half-open state machine, optional fallback.
//!
//! Decorators wrap `Arc<dyn Provider>` and return `Arc<dyn Provider>`, so they
//! compose freely. Typical stacking (outermost first):
//!
//! ```text
//! CircuitBreaker → Retry → Budget → base Provider
//! ```
