Case contract

Input {last_fall_days (or null), secondary_dx, aid, iv, gait, mental}. Toy points: a fall within the last 90 days (inclusive) 25; secondary diagnosis 15; aid none/bedrest/nurse 0, crutches/cane/walker 15, furniture 30; IV access 20; gait normal/bedrest/immobile 0, weak 10, impaired 20; mental status "forgets" or "overestimates" (overestimates own ability) 15, "oriented" 0. Risk: 0-24 LOW, 25-44 MODERATE, >= 45 HIGH. Return {score, risk}.

Why this case matters

Nursing risk scores map categorical observations to weighted points; recency windows, category tables and band edges fail independently.
