1//! The single error type of the benchmark core.
2//!
3//! Every fallible entry point returns [`Result`]. The variants map one-to-one to
4//! the ways running a case can fail before a [`CaseResult`] is even reached: a
5//! malformed case, a strategy that does not deserialize, unusable data, the
6//! backtest engine refusing to run, or a bad command envelope. A case whose
7//! recomputed report simply *disagrees* with its expectation is **not** an error
8//! — that is a successful [`CaseResult`] with `passed == false`.
9//!
10//! [`CaseResult`]: crate::CaseResult
