```
-type failure() ::
          #{code := scope_cleanup_failed,
            primary := {ok, term()} | exception(),
            cleanup := {error, term()} | exception(),
            atom() => term()}.
```

Both outcomes when cleanup failed. primary contains the callback's ordinary return or exception; cleanup contains its separate error or exception. Resource-specific wrappers may add recovery handles to this map.
