//! Compile-time assertions that the umbrella re-exports what each feature
//! advertises.
//!
//! A feature graph rots silently: a capability flag keeps resolving long after
//! the re-export behind it was renamed or dropped, because nothing referenced
//! it. These assertions are what make the flag surface falsifiable.

/// The engine is flattened into the umbrella, so `shepherd::Harness` resolves
/// without the consumer ever naming `shepherd-core`. That indirection is the
/// point of the crate.
