> **(medium)** This early-return treats any unmanageable instance of a known
> entity type as detached without verifying it was ever persisted, so a truly
> transient unenhanced object referenced without cascade now passes the check
> and fails later (or silently persists a broken FK). Line 824 also adds
> `_broker.isDetached(obj, true)`, a DB round-trip inside the flush path for
> every manageable object without a state manager. Can both paths at least
> verify a non-null/assigned identity before assuming detached?
