 * Assignment cache keys are only on the subject and flag level, while a combination of keys and
 * fields are used for uniqueness checking. This way, if an assigned variation or bandit action
 * changes for a flag, it evicts the old one. Then, if an older assignment is later reassigned, it
 * will be treated as new.
