Kernrechtsfrage
Whether the federal appeal met the minimum reasoning requirements under Art. 42 BGG
Extrahierter Entscheid
It did not, because it failed to address the decisive cantonal reasoning and merely repeated prior arguments.
Extrahierte Begründung
The appellant did not concretely explain how the cantonal court's assessment of the valid income and disability degree violated federal law or was manifestly incorrect; appellatory criticism is insufficient.
