//! Split out of the parent test file, which sits on the source-length
//! ratchet's legacy list. These four cases are one contract: whether the
//! ambient mutation session reaches the ACP wire as `audit`, and what the
//! typed `mutationStatus` reads when it does not. The child reaches the
//! parent's fixtures through its own `use super::*`.
