//! State contextual verification and storage code for Zebra. 🦓
//!
//! # Correctness
//!
//! Await UTXO and block commit requests should be wrapped in a timeout, because:
//! - await UTXO requests wait for a block containing that UTXO, and
//! - contextual verification and state updates wait for all previous blocks.
//!
//! Otherwise, verification of out-of-order and invalid blocks can hang indefinitely.
