//! Unit tests for the governor's internals (#1211).
//!
//! Lifted out of `governor.rs`: the house rule is that no `#[cfg(test)] mod
//! tests` block lives in a source file — every suite is a file under
//! `src/tests/` registered in `mod.rs`. The end-to-end gate tests live in
//! `governor_gates_test`; this file covers the pure pieces those drive.
