Questione giuridica chiave
Whether the cantonal court established the facts manifestly inaccurately and should have ordered a multidisciplinary expert opinion.
Decisione estratta
The factual findings were not manifestly inaccurate. The medical file supported an 80% capacity in adapted work, and a multidisciplinary expert opinion would not have added objective elements.
Motivazione estratta
The medical reports were coherent and more persuasive than the disappointing observation stages. The later report by Dr. B. described deterioration but not objective work incapacity. The asserted difficulties were better explained by pain-management limits and personality traits than by an invalidating psychiatric disorder.
