Figure 26.4 The chapter's development discipline made spatial: one pool of labeled
tickets divided into three disjoint homes. A handful live inside the guide as
demonstrations; the development set is the sparring bench you re-run and study
freely; and the sealed test set (in accent) is the envelope opened rarely, the
only number you report. A ticket that tries to live in two sets at once is a
leaked exam answer—struck out here, because disjointness is the whole point.
