#includes(*keys) ⇒ Object

The keys passed to .includes(...) travel from this class-method call into the Request built by the subsequent finder call. Storing them in a class instance variable meant concurrent threads calling .includes on the same model shared (and corrupted) one slot, so they're held in thread-local storage keyed by the class instead.
