//! sb-sim — point-in-time market simulator + reference agents (Phase 1).
//!
//! The engine feeds an [`Agent`] a [`sharpebench_protocol::MarketObservation`] that only
//! ever contains data at or before the decision date (look-ahead is structurally
//! impossible — [`Dataset`] never hands out a future bar), applies the resulting
//! orders with transaction costs and seeded execution slippage, and emits an
//! [`sharpebench_core::Run`] (per-period returns + decision trace) ready for scoring.
