DEMO_01 no longer carries a NOTNULL rule for ID: it is the table's buskey, and Data Controller applies NOT NULL to a primary key by itself, so the demo now shows the behaviour rather than a rule that duplicates it. The clip's range-rule scene showed a special missing being rejected by MINVAL. It now shows the missing accepted in both AMOUNT (MINVAL 1) and SCORE (MAXVAL 100), and a real number out of range - 0, then 200 - rejected. Two captions were also wrong and are corrected: the period in a special missing is optional (the demo's own row 2 holds .a), and ID is NOT NULL because it is the primary key.
