//! The typed failures a gateway dispatch can end in, downcast by the HTTP
//! layer to choose a status and envelope.
//!
//! [`DispatchError`] separates a failure that happened before the audit row
//! was opened from one already recorded against it, so the route handler
//! knows whether it still owes an audit write.
