//! Engine-level specifications.
//!
//! Engines are composed programs (DFA, eval, scatter, dataflow).
//! Their specs define invariants that must hold beyond individual
//! op correctness.

///
/// Engines are not individual ops; they are full programs with cross-op
/// guarantees such as determinism, termination, and output ordering.
/// The conform engine runs these invariants after every op-level gate
/// has passed, because local correctness does not imply global correctness.
